IWMI in Nepal

Large-scale male outmigration has placed new pressures on both men and women, especially regarding labour division in farm households and involvement in Water Users Associations (WUAs). This paper illustrates how the interplay between existing gender norms, male migration, remittances, and alternative sources of male labour influence women’s agency and WUA decision-making processes in Nepal. Despite official quotas aimed at promoting women’s participation in WUAs, some women prefer to monetise membership contributions rather than actively engage with the organisation. Others pursue strategic interests through changing WUA rules and, in the process, bringing about an adjustment of cultural norms. Women’s agency is derived not only from their knowledge of irrigation systems features and their ability to manage them; it is also related to their ability to learn new organisational skills and to apply them in the WUA context to negotiate and mobilise rules and resources. Women (re)shape their WUA involvement in conjunction with their farming strategies, their view of the WUA’s functionality, and whether they perceive the involvement as either an opportunity for productive engagement or as merely an increase in their already heavy workload.

Climate variability and insufficient irrigation are primary constraints to stable and higher agricultural productivity and food security in Nepal. Agriculture is the largest global freshwater user, and integration of surface- and ground-water use is frequently presented as an strategy for increasing efficiency as well as climate change adaptation. However, conjunctive management (CM) planning often ignores demand-side requirements and a broader set of sustainable development considerations, including ecosystem health and economics of different development strategies. While there is generic understanding of conjunctive use, detailed technical knowhow to realize the CM is lacking in Nepal. This article presents a holistic framework through literature reviews, stakeholders consultations and expert interviews for assessing CM and implementation prospects from a systems-level perspective. We demonstrate the framework through a case study in Western Nepal, where climatic variability and a lack of irrigation are key impediments to increased agricultural productivity and sustainable development. Results show that knowledge of water resources availability is good and that of water demand low in the Western Terai. Additional and coordinated investments are required to improve knowledge gaps as well as access to irrigation. There is therefore a need to assess water resources availability, water access, use and productivity, to fill the knowledge gaps in order to pave pathways for CM. This paper also discusses some strategies to translate prospects of conjunctive management into implementation.

Migration impacts left-behind populations, disrupting established norms of social interaction, participation, and inclusion. In western Nepal, labour migration is common among young men, with implications for household and community participation among those left behind, who are predominately women. In this study, we use mixed methods to examine how labour migration impacts the social inclusion of migrant households, especially, of left-behind women in community groups and activities. For our analysis, we use quantitative survey data from over 3600 households in the Karnali and Mahakali River Basins of western Nepal and qualitative data from 16 focus group discussions and 37 in-depth interviews held in the same region. Our analysis reveals substantial heterogeneity in the experiences of women and households left behind by migrants. Women’s opportunities to participate in economic systems such as natural resource user committees and non-governmental organisation trainings are moderated by intersecting identities including gender, caste/ethnicity, kinship, age, and economic status. Young women from nuclear, low caste, and poor households with limited social ties suffer from disadvantaged positions and face restricted access to spaces of participation. Accordingly, left-behind women’s opportunities to benefit from community resources remain dependent on their caste and kinship networks. These findings contribute to ongoing debates on the impacts of migration, and can help inform improved targeting of interventions to advance gender equity in rural Nepal.

Motivation: COVID-19 has revived focus on improving equitable access to water, sanitation and hygiene (WASH) and health services in developing countries. Most public programming tends to rely on economic indicators to identify and target vulnerable groups. Can expanded targeting criteria that include social status help to improve not only targeting, but also equity in access to WASH and health services? Purpose: This paper assesses the role of social identity in mediating access to WASH and health services, controlling for economic disadvantages such as household wealth, income sources and assets. Methods and approach: We use regression analysis applied to the 2016 Nepal Demographic and Health Survey (DHS) to estimate the relationships between social identity and access to WASH and health services, controlling for wealth (using wealth index quantiles), and remittances (using indicator variables for domestic and international remittances). Findings: We find that differences in access are mediated in large part by caste, and religious and ethnic identity, especially in rural areas; suggesting that the supply of such services is lower for historically disadvantaged communities. In addition, communities with lowest access are not necessarily the most economically disadvantaged, indicating that relying solely on traditional economic indicators to target programs and interventions may not be sufficient to improve equity in access to public health services. Policy implications: The results make a case for broadening indicators beyond the economic criteria for improving targeting of public funds for more inclusive development.

This paper analyses the relationship between cyclical labour migration and agrarian transition in the uplands of Nepal, Ethiopia and Kenya. It shows that while migration decision-making is linked to expanding capitalist markets, it is mediated by local cultural, political and ecological changes. In turn, cyclical migration goes on to shape the trajectory of change within agriculture. The dual dependence on both migrant income and agriculture within these upland communities often translates into an intensifying work burden on the land, and rising profits for capitalism. However, on some occasions this income can support increased productivity and accumulation within agriculture – although this depends on both the agro-ecological context and the local agrarian structure.

The Nepalese Sunsari Morang Irrigation district is the lifeblood of millions of people in the Koshi River basin. Despite its fundamental importance to food security, little is known about the impacts of climate change on future irrigation demand and grain yields in this region. Here, we examined the impacts of climate change on the irrigation demand and grain yield of wheat crop. Climate change was simulated using Representative Concentration Pathways (RCPs) of 4.5 and 8.5 for three time horizons (2016–2045, 2036–2065, and 2071–2100) in the Agricultural Production Systems Simulator (APSIM). For the field data’s measured period (2018–2020), we showed that farmers applied only 25% of the irrigation water required to achieve the maximum potential grain yield. Actual yields were less than 50% of the potential yields. Projected irrigation water demand is likely to increase for RCP4.5 (3%) but likely to decrease under RCP8.5 (8%) due to the truncated crop duration and lower maturity biomass by the end of the 21st century. However, simulated yields declined by 20%, suggesting that even irrigation will not be enough to mitigate the severe and detrimental effects of climate change on crop production. While our results herald positive implications for irrigation demand in the region, the implications for regional food security may be dire.

Located on the south-facing slope of the Himalayas, Nepal receives intense, long-lasting precipitation during the Asian summer monsoon, making Nepal one of the most susceptible countries to flood and landslide hazards in the region. However, sparse gauging and irregular measurement constrain the vulnerability assessments of floods and landslides, which rely highly on the accuracy of precipitation. Therefore, this study evaluates the performance of Satellite-based Precipitation Products (SPPs) in the Himalayas region by comparing different datasets and identifying the best alternative of gauge-based precipitation for hydro-meteorological applications. We compared eight SPPs using statistical metrics and then used the Multi-Criteria Decision-Making (MCDM) technique to rank them. Secondly, we assessed the hydrological utility of SPPs by simulating them through the GR4J hydrological model. We found a high POD (0.60–0.80) for all SPPs except CHIRPS and PERSIANN; however, a high CC (0.20–0.40) only for CHIRPS, IMERG_Final, and CMORPH. Based on MCDM, CMORPH and IMERG_Final rank first and second. While SPPs could not simulate daily discharge (NSE lt; 0.28), they performed better for monthly streamflow (NSE gt; 0.54). Overall, this study recommends CMORPH and IMERG_Final and improves the understanding of data quality to better manage hydrological disasters in the data-sparse Himalayas. This study framework can also be used in other Himalayan regions to systematically rank and identify the most suitable datasets for hydro-meteorological applications.

Ensuring the long-term functionality of community-managed rural water supply systems has been a persistent development challenge. It is well established that the technicalities of keeping the systems going are impacted by complex political, social, financial, and institutional challenges. While the shift to federal, three-tiered governance allocates concurrent responsibility for drinking water management to the local government with federal and provincial governments, water and sanitation user groups continue to shoulder the management of local supply systems voluntarily. All three levels have jurisdiction over water-related services resulting in confusion of roles. This study focuses on the local level, where community management of water and sanitation decentralisation is the key approach in this complex tangle of diverse institutions with different actors managing and governing water. User Groups and their Committees in the Guras Rural Municipality of Dailekh district, Karnali province, in West Nepal, provided the case study, which was analysed using Ostromapos;s well-recognised Eight Principles for Sustainable Governance of Common-Pool Resources. The community-based model, established formally through the Water Resource Act 1992 (2049 BS), is critically analysed in light of the changing socioeconomic context through the intervening years. The results highlight the need for stronger collaboration between the rural municipality and users to achieve good water supplies and the risks of losing access and voice in water management for women and marginalised people when inactive user groups are replaced by private or group interests taking control of the water access.

Solar-powered irrigation pumps are a vital tool for both climate change adaptation and mitigation. Since most developing countries cannot fully utilize large-scale global funds for climate finance due to limited institutional capacities, small-scale solar irrigation pumps (SIPs) can provide a climate-resilient technological solution. We study the case of a subsidized SIP program in Nepal to understand who likely benefits from a small-scale climate finance program in a developing country setting. We analyze government data on profiles of farmers applying for SIPs and in-depth interviews with different actors along the SIP service chain. We find that vulnerable farmers (women, ethnic minorities, and poor farmers) were less likely than wealthier and non-minority farmers to have access to climate finance subsidies. Even though the government agency gave preference to women and ethnic minority farmers during beneficiary selection, an unrepresentative pool of applicants resulting from social and institutional barriers that prevented them from applying to the program led to an inequitable distribution of subsidized SIPs. The lack of a clear policy framework for allocating climate finance subsidies was a significant constraint. Lack of periodic updating of SIP prices and poor provision of after-sale services were also responsible for the inequitable distribution of subsidized SIPs. We recommend the involvement of local governments in soliciting applications from a wider pool of farmers, periodic revision of SIP prices to reflect market price, replacement of the current fixed subsidy scheme with a variable subsidy scheme, and mandatory provisions of after-sales services.

An understanding of water sufficiency provides a basis for informed-planning, development and management of water resources. This study assessed spatio-temporal distribution in water sufficiency in the Extended East Rapti watershed in Nepal. The “Palika” (local government unit) is considered as a spatial-scale and seasons and future periods as temporal-scale. The water sufficiency was evaluated based on water sufficiency ratio (WSR) and water stress index (WSI). A hydrological model was developed to simulate water availability. An ensemble of multiple Regional Climate Models was used for assessing climate change impacts. Results showed water sufficiency by mid-century is projected to decrease; WSR by 40% and WSI by 61%. Despite projected decrease in water sufficiency, annually available water resources are projected as sufficient for the demands until the mid-century, however, seasonal variability and scarcity in future is projected in most Palikas. Such results are useful for water security planning in the Palikas.

Cascading hazards are becoming more prevalent in the central Himalayas. Primary hazards (e.g., earthquakes, avalanches, and landslides) often trigger secondary hazards (e.g., landslide dam, debris flow, and flooding), compounding the risks to human settlements, infrastructures, and ecosystems. Risk management strategies are commonly tailored to a single hazard, leaving human and natural systems vulnerable to cascading hazards. In this commentary, we characterize diverse natural hazards in the central Himalayas, including their cascading mechanisms and potential impacts. A scientifically sound understanding of the cascading hazards, underlying mechanisms, and appropriate tools to account for the compounding risks are crucial to informing the design of risk management strategies. We also discuss the need for an integrated modeling framework, reliable prediction and early warning system, and sustainable disaster mitigation and adaptation strategies.

Women and water share a great deal of nexus in several ways. However, women have still minimal control over the management of water resources, making them more vulnerable to climate change. This paper assesses how climate change impacts differently across different women groups using an intersectionality lens, thereby exploring the situation of gender mainstreaming in water sector in three communities, namely, Karaiya, Basauli, and Dadagaun in Khairahani Municipality located in the East Rapti watershed, Nepal. In this perception-based study, we conducted three key informant interviews and household interviews with 45 women of different castes, ages, communities, education levels, and occupations. The results showed that different groups of women perceive climate change and its impact differently. For instance, women engaged in agriculture are more aware of the impact of climate change and are affected more by it because of changing trends in rainfall and temperature resulting in water shortage and flooding. On the other hand, they experience more physical and mental stress because of a higher responsibility of both agriculture and household . Despite 80% of female involvement in water user committees, there is a gap in participation by all groups of women. Irrespective of literacy and work engagement, women of Karaiya and Basauli, were less aware and active than Dadagau in various water development and management activities because of time constraints, family background, lesser interest, and awareness. Therefore, more efforts are required to achieve significant progress in gender mainstreaming considering intersectionality in the water sector and climate change.

A static and apolitical framing of women’s empowerment has dominated the development sector. In contrast, we assess the pertinence of considering a new variable, the will to change, to reintroduce dynamic and political processes into the way empowerment is framed and measured. This article uses a household survey based on the Women’s Empowerment in Agriculture Index (WEAI) and qualitative data collected in Nepal to analyze how critical consciousness influences women’s will to change the status quo and the role of visible agency, social structures, and individual determinants in those processes. A circular process emerges: women with higher visible agency and higher critical consciousness are more willing to gain agency in some, but not all, of the WEAI empowerment domains. This analysis advances current conceptualizations of empowerment processes: the will to change offers valuable insights into the dynamic, relational and political nature of women’s empowerment. These findings support the design of development programs aiming at increasing visible agency and raising gender critical consciousness and argue for improving the internal validity of women’s empowerment measurement tools.

Quantifying water-related ecosystem services (WES) helps to secure limited and valuable water resources sustainably. Mainstreaming these ecosystem services into policy and decision-making requires accurate information at the local level. This paper aims to quantify provisioning and regulating freshwater ecosystem services potential in the Kangchenjunga Landscape using a hydro-ecological model. This study is the first to use the J2000 hydrological model to estimate annual and seasonal WES. The model output was validated against snow-cover and river discharge, after conducting a sensitivity analysis of the input parameter. High precipitation and low evapotranspiration resulted in rich water availability in the landscape. It was found that the precipitation amount in the landscape is highly seasonal, resulting in high variation in water availability. Snowfall, accounting for 4% of the total precipitation still plays an important role in regulating water resources. Nearly 100% of the discharge during the dry period originates from groundwater and melt runoff. This study highlights the importance of the presence of snow and glacier to sustain the ecosystem in the landscape. This model-derived information could further be used for decision-making and evaluating the impact of climatic and land use changes.

Many communities in South Asia are highly exposed and vulnerable to weather and climate hazards, and climate services play an important role in managing present and future climate risks. Here we take stock of ongoing climate service activities under the Asia Regional Resilience to a Changing Climate (ARRCC) Met Office Partnership programme. ARRCC aims to strengthen climate resilience in South Asia through co-producing weather and climate services, building institutional capacities, and enhancing coordination across the region and in focal countries: Afghanistan, Bangladesh, Nepal and Pakistan. We identify what is working well and challenges that remain in the provision and uptake of climate services, focusing on examples of applying seasonal forecasts, sea-level rise projections, and extreme rainfall information for hydropower decisions. We demonstrate the value of building equitable and sustainable partnerships, enhancing knowledge sharing, strengthening evaluation, and approaches that combine model information within a decision-centred framework. Based on experiences in ARRCC, we find that climate information alone is often insufficient to meet decision-maker needs, and discuss the role for new climate impact services that integrate climate information with knowledge and tools on climate impacts and vulnerabilities.

The Constitution of Nepal 2015 enshrines everyone’s right of access to clean water for drinking and the right to food. The common operationalization of the right to water for drinking is providing access to infrastructure that brings water for drinking and other basic domestic uses near and at homesteads. Challenges to achieving this goal in rural areas include: low functionality of water systems; expansion of informal self supply for multiple uses; widespread de facto productive uses of water systems designed for domestic uses; growing competition for finite water resources; and male elite capture in polycentric decision-making. This paper traces how the Nepali government and nongovernmental organizations in the water, sanitation and hygiene (WASH), irrigation and other sectors have joined forces since the early 2000s to address these challenges by innovating community-led multiple use water services (MUS). The present literature review of these processes complemented by field research supported by the Water for Women Fund focuses on women in vulnerable households. Overcoming sectoral silos, these organizations support what is often seen as the sole responsibility of the WASH sector: targeting infrastructure development to bring sufficient water near and at homesteads of those left behind. Women’s priorities for using this water are respected and supported, which often includes productive uses, also at basic volumes. In line with decentralized federalism, inclusive community-led MUS planning processes build on vulnerable households’ self supply, commonly for multiple uses, and follow their priorities for local incremental infrastructure improvements. Further, community-led MUS builds on community-based arrangements for ‘sharing in’ and ‘sharing out’ the finite water resources in and under communities’ social territories. This realizes the constitutional right to food in line with the Nepal Water Resources Act, 1992, which prioritizes core minimum volumes of water for everyone’s domestic uses and many households’ irrigation. Evidence shows how the alleviation of domestic chores, women’s stronger control over food production for nutrition and income, and more sustainable infrastructure mutually reinforce each other in virtuous circles out of gendered poverty. However, the main challenge remains the inclusion of women and vulnerable households in participatory processes.

Successful community institutions in the global South, which are contributing to livelihoods’ improvement while conserving water and other natural resources, can sustainably build the resilience that policy makers at different tiers are seeking. This article assesses different models of community institutions in Nepal in governing water resources from various lenses, based on Ostrom’s and others’ design principles, including bricolage. Illustrated by three empirical cases, it analyses key features of community institutions in integrated water governance, their contributions to health, nutrition, food security, and environmental conservation, and ways for empowering these institutions as viable and sustainable solutions to address various livelihood challenges. However, inequalities along gender, caste, and ethnicity lines persist. We argue that the recently established local governments under the federal system in Nepal provide new opportunities for gender and social inclusion.

This report explores the agrarian history of Nepal over the last 500 years, and the historical, social, and political trajectories that still shape modern agrifood systems in Nepal. The report is organised according to the main epochs in Nepal’s political-economic history. The study explores the complex layers of factors which vary across space according to contemporary and historic state formations, the local agroecology and indigenous and imported cultural-economic institutions and technologies that shape regional diversity in modes of production and food production systems across Nepal. The study is based on readily available documents including secondary literature and archival data as data sources.

As a part of the Transforming Agrifood Systems in South Asia (TAFSSA) initiative’s holistic food systems approach, IWMI led a study tracing the historical evolution of food systems in Nepal. The expert consultation aimed to solicit views on framing and situating the historical study within the current food systems-related discussions. The study is conducted by Dr. Fraser Sugden from the University of Birmingham, Dr. Suresh Dhakal and Dr. Janak Rai from Tribhuvan University, Kathmandu. Stakeholders offered substantial feedback on increasing the geographical and community scope of the study, important timelines to include, and relevant issues of the local agrifood system relevant for the region.

Existing climate projections and impact assessments in Nepal only consider a limited number of generic climate indices such as means. Few studies have explored climate extremes and their sectoral implications. This study evaluates future scenarios of extreme climate indices from the list of the Expert Team on Sector-specific Climate Indices (ET-SCI) and their sectoral implications in the Karnali Basin in western Nepal. First, future projections of 26 climate indices relevant to six climate-sensitive sectors in Karnali are made for the near (2021–2045), mid (2046–2070), and far (2071–2095) future for low-and high-emission scenarios (RCP4.5 and RCP8.5, respectively) using bias-corrected ensembles of 19 regional climate models from the COordinated Regional Downscaling EXperiment for South Asia (CORDEX-SA). Second, a qualitative analysis based on expert interviews and a literature review on the impact of the projected climate extremes on the climate-sensitive sectors is undertaken. Both the temperature and precipitation patterns are projected to deviate significantly from the historical reference already from the near future with increased occurrences of extreme events. Winter in the highlands is expected to become warmer and dryer. The hot and wet tropical summer in the lowlands will become hotter with longer warm spells and fewer cold days. Low-intensity precipitation events will decline, but the magnitude and frequency of extreme precipitation events will increase. The compounding effects of the increase in extreme temperature and precipitation events will have largely negative implications for the six climate-sensitive sectors considered here.

Enhancing accountability has become an important objective of the governance reforms over the past two decades. Yet, only a few studies have explored the use of social accountability tools in the water sector in particular. This report aims to fill this gap, based on a case study of a donor-funded water, sanitation and hygiene (WASH) program in Nepal. We document and analyze the effects of two types of social accountability tools implemented by the program: public hearings and social audits. We examined how these tools have contributed to increased transparency, participation, voice and accountability, and in turn discuss their potential to reduce corruption. We relied on qualitative methods to collect data in two case study water supply schemes in two districts of Nepal. The study found that the social accountability tools provided a platform for water users to participate and deliberate on issues related to the execution of WASH schemes. However, the scope of accountability narrowly focused on the integrity of the water user committees but did not provide the political resources and means for communities to hold funding and implementing agencies accountable. Furthermore, attention to budget management has not provided space to address environmental and social justice issues related to payment of wages, access to water and decision-making processes in the design of the water scheme and water allocation. Findings from the study also indicate that the concept of deliberation and downward accountability, as envisioned in international development discourses, does not necessarily match with local power relationships and local cultural norms.

Motivation: Power relations, and the politics shaping and reshaping them, are key to determining influence and outcomes in water governance. But current discourse on water governance tends to present decision-making as neutral and technical unaffected by political influences. Purpose: Taking Nepal as a case, this article examines the close interlinkages between bureaucratic and political competition that indirectly influence decisions and outcomes on water governance, while placing this within the context of state transformation. Approach and Methods: An in-depth case study examines the interactions of politicians and bureaucrats shaping decisions on water governance. It draws on semi-structured interviews and power-mapping to reveal insights from key stakeholders with decision-making power in national management of water resources. Findings: Political competition drives the country’s development agenda and planning, resulting in fragmented development planning. It works in tandem with the prevailing bureaucratic competition in water resources management. It highlights the need to link the discourse and analysis water governance with processes of state transformation. The current fragmented development planning processes could serve as entry points for civil society groups and the wider society to convey their voice and exert their influence. Policy implications: Following federalism, the political transfer of power and decision-making, to achieve political representation and social justice, rests with locally elected governing bodies. This coincides with the government’s push to manage water resources through river basin planning. There is a need for greater participation from the local governing bodies and understanding of politics and power shape water governance.

Springs in the mountains and hills are getting affected by both climatic and non-climatic changes. Hydrologic models are used to simulate the response of spring systems to the changes; however, only a limited number of studies using the hydrologic modeling approach have been accomplished on studying springs and spring-dominated watersheds in Nepal. This research aimed at understanding changing hydrological processes through hydrologic modeling in a spring catchment. A micro-catchment named apos;Sikharpurapos; of West Seti watershed of Nepal was selected to get insights into the process influencing the spring system. The RRAWFLOW models with gamma distribution and time variant IRFs were calibrated and validated for the catchment to get the best fit model. The discharge was simulated according to the future projected climate scenarios. Then, a water balance was assessed for the micro-catchment. The results showed that understanding of likely response of hydrologic variables to potential future climate scenarios is critical for water resource management. It was estimated that the spring discharge would be decreased by more than 40 percentage after 50 years mainly due to the increase in evapo-transpiration (91.47% of the precipitation). Evapo-transpiration was found as a major hydrologic process impacting upon water balance in the spring catchment; therefore, its management for better spring resource conservation is recommended by considering high evapo-transpiration months, water deficient period and crop factor. The change in the storage was observed to be 51.78%; so, detail isotopic analysis and long-term monitoring of water balance is required for further characterization of water balance components.

This analysis investigates the potential mechanism and the practical significance of the impacts of agricultural value chain development in a geographically challenging rural area of a developing country. We use data from a carefully designed primary survey administered in the hill and mountainous region in Western Nepal. Using the inverse probability weighted regression adjustment method, we show that linking small-scale producers with regional and local traders can help increase agricultural income. We unpack the potential mechanism of the impact pathway and show that the increase in agricultural income is a consequence of higher agricultural revenues, owing to a higher volume of sales at lower prices. We argue that value chain intervention in rural areas, where land is not fully exploited, can lead to acreage expansion or crop switching, which eventually results in higher supply at lower output prices. The positive impact on household income is practically significant in that it translated into improved food security, dietary diversity and household resilience. These findings are robust to various specifications. Targeted value chain interventions that strengthen and stabilize small-scale producers’ access to markets can contribute to rural poverty reduction via an increase in agricultural income.

With the increasing population and accelerated urbanization, demands for water are rising for different sectors around the world, including in South Asia. Integrated water resource management (IWRM) offers a promising potential to address multifaceted water demands. This study therefore aimed to address this issue by (i) reviewing key issues related to water, land, and food in South Asian countries, (ii) exploring the prevalent irrigation management strategies in those countries, and (iii) examining the IWRM situation based on a Nepalese case study, and it proposes some options to support effective implementation of IWRM. South Asia, the home to 24% of the worldapos;s population with only 15% and 7% of the worldapos;s arable and permanent crop land and water resources, respectively, is the worst-affected region in the world from undernourishment. Surface irrigation is the dominant irrigation application method in the region, which incurs high water losses due to the lack of flexible water control structures in canal networks. The Nepalese case study revealed a lack of clear institutional arrangements to implement IWRM and disparate and conflicting views about IWRM. Creation and strengthening of basin-level water user organizations, technological improvements, and awareness-raising activities are some potential ways forward to implement IWRM.

Water resources can play significant roles in development pathways for water-endowed, low-income countries like Nepal. This article describes three visions for water resource development in the Karnali and Mahakali Basins of Western Nepal: state-led development, demand-driven development and preservation of ecosystem integrity. The analysis calls attention to water use trade-offs, including those resulting from national priorities such as infrastructure-based hydropower and irrigation, from local drinking water demand, and from environmental conservation concerns. While these visions of water resources development do diverge, common trends appear, including acknowledgment of water management’s role in expanding energy access and increasing agricultural productivity.

The COVID-19 pandemic has significantly changed the context of global migration. From a migration perspective, the pandemic is a source of insecurities that challenge migrants, their livelihoods and migration governance. Meanwhile, curtailment in movement has led to economic decline affecting labour markets. For migrant origin and hosting countries, this poses multidimensional development challenges. Analysis from March to August 2020 of China, Ethiopia, Kyrgyzstan, Moldova, Morocco, Nepal and Thailand highlights the varying ways in which they are all severely affected by the disruptions in migration, suggesting a potentially emerging complex situation in migration patterns and pathways. The disruptions in migration and remittances have had a profound impact on migrants and migrant-sending households. The uncertainty of migration returning to pre-pandemic levels and the potential of lasting consequences on migrants and migration patterns and pathways, suggests a future of greater risk and exploitation, and a wider gap between formal and informal migration. This paper calls for greater mobility cooperation between countries and suggests strengthening mobility migration frameworks and policies for safer migration and for the rights of migrants.

Climate change/variability and subsequent exacerbation of extremes are affecting human and ecological health across the globe. This study aims at unpacking hydro-climatic extremes in a snow-fed Marshyangdi watershed, which has a potential for water infrastructure development, located in Central Nepal. Bias-corrected projected future climate for near (2014–2033) and mid-future (2034–2053) under moderate and pessimistic scenarios were developed based on multiple regional climate models. Historical (1983–2013) and future trends of selected climatic extreme indices were calculated using RClimDex and hydrological extremes using Indicators of Hydrologic Alteration tool. Results show that historical trends in precipitation extremes such as number of heavy and very heavy precipitation days and maximum 1-day precipitation are decreasing while the temperature-related extremes have both increasing and decreasing trends (e.g., warm spell duration index, warm days and summer days are increasing whereas cold spell duration index, cool days and warm nights are decreasing). These results indicate drier and hotter conditions over the historical period. The projected future temperature indices (hot nights, warm days) reveal increasing trend for both the scenarios in contrast with decreasing trends in some of the extreme precipitation indices such as consecutive dry and wet days and maximum 5-day precipitation. Furthermore, the watershed has low mean hydrological alterations (27.9%) in the natural flow regime. These results indicate continuation of wetter and hotter future in the Marshyangdi watershed with likely impacts on future water availability and associated conflicts for water allocation, and therefore affect the river health conditions.

This report examines social equality aspects related to resource recovery through solid waste composting and wastewater irrigation. The report shows that women are represented in greatest numbers at the base of the recycling chain, most often as informal waste pickers and as sorters of recyclables with limited access to resources and upward mobility. Despite a wide gender gap in the solid waste and sanitation sectors, women play a key role in both municipal waste reduction and food safety where irrigation water is unsafe. Analyzing the gender dimension is important for understanding household responses to recycling programs, differences between the formal and informal sectors as well as along the waste-to-resource value chain from collection to treatment and reuse. The report stresses the important role of women in household waste management, including waste segregation, and the power of women-dominated waste picker associations, where the informal sector plays an essential role alongside the formal sector.

This article investigates water security in Nepal from the perspective of the water-energy-agriculture (food) nexus, focusing on pathways to water security that originate in actions and policies related to other sectors. It identifies promoting development of Nepal’s hydropower potential to provide energy for pumping as way to improve water security in agriculture. Renewable groundwater reserves of 1.4 billion cubic meters (BCM), from an estimated available balance of 6.9 BCM, could be pumped to irrigate 613,000 ha of rainfed agricultural land in the Terai plains, with a potential direct economic gain of USD 1.1 billion annually and associated benefits including promotion of energy-based industry, food security and local employment. Governance also plays an important role in addressing water security. We conclude that a nexus-based approach is required for effective water management and governance.

Himalayan regions have increasing sediment yield due to undulating topography, slope and improper watershed management. However, due to limited observation data, and site accessibility issues, less studies have quantified sedimentation loads in the Himalayas, especially Nepal. This has hindered the investments on run-of-river hydropower projects as high and unpredicted sedimentation has increased losses in hydropower production. Therefore, there is a need to understand key physical processes driving sedimentation in these regions, with the available data. This study used the Soil and Water Assessment Tool (SWAT) to estimate the sedimentation yields in the Kaligandaki basin of Nepal, which is an important tributary that drains into the Ganges. Multi-source data from field observations, remote sensing platforms, surveys and government records were used to set up and run the SWAT model for the Kaligandaki basin from 2000 to 2009. Results for the 10-year model run indicate that 73% of the total sediment load is estimated to come from the upstream regions (also known as High Himalayan region), while only 27% is contributed from the Middle and High Mountain regions (where land management-based interventions were deemed most feasible for future scenarios). The average sediment concentration was 1986 mg/kg (ppm), with values of 8432 and 12 mg/kg (ppm) for maximum and minimum, respectively. Such high sedimentation rates can impact river ecosystems (due to siltation), ecosystem services and hydropower generation. In addition, model results indicate the need for better high frequency observation data. Results from this study can aid in better watershed management, which is aimed at reducing sedimentation load and protecting Himalayan rivers.

The last decade has witnessed rapid progress in energy cooperation between the countries of the BBIN (Bangladesh, Bhutan, India and Nepal) sub-region. Cooperation has been bilateral, with each of the countries entering into separate energy development and trade agreement with India, broadly similar to the water sector where national governments engage bilaterally on transboundary cooperation and dispute resolution. A more recent wave of electrical grid interconnections and hydro-energy cooperation has emerged with governments increasingly shifting from bilateral to multilateral energy-sharing agreements. This trend holds considerable potential for regional transboundary water governance. Based on documentary and media analysis along with interviews of key BBIN policy-makers, we identify and examine in this paper four factors for future progress: 1) technical cooperation can be extended to information-sharing for policies and institutions to regulate and manage water resources; 2) India must seize the opportunities and benefits of enhanced regional leadership in the region; 3) simultaneous informal discussion and diplomatic negotiation of water, energy and their nexus can provide BBIN countries the opportunity to highlight potential gains of cooperation and interstate interdependencies; and 4) regional cooperation can give a strong impetus to nations for advancing structural reforms, building institutions and capacity, developing a shared knowledge base, bridging infrastructural gaps, attracting private sector participation, and addressing poverty alleviation goals including job creation.

Study region: Karnali-Mohana river basin, Western Nepal. Study focus: This study aims to project future climate and assess impacts of climate change (CC) on water availability in the Karnali-Mohana (KarMo) basin. Bias-corrected future climate was projected based on ensembles of multiple models selected from a set of 19 regional climate models (RCMs). The impacts on water availability were then assessed by forcing a well calibrated and validated hydrological model with projected future precipitation (P) and temperature (T) for various climatic scenarios. New hydrological insights for this region: Results showed that future T is projected to increase spatio-temporally with higher rate for the mountain stations in the winter season; whereas future P has no distinct spatio-temporal trend but increase in dry season precipitation for future periods. The projected changes in P, T and evapotranspiration are expected to alter average annual flow at the outlets of the KarMo and its sub-basins, albeit with varying rate. The simulated results showed higher impacts in water availability at higher altitudes, thus indicating higher vulnerability of northern mountainous region to CC than the southern flatlands. Being the first ever study of such nature in the study area, these results will be useful for planning and development of climate-resilient water development projects in the region.

Water security is a key in achieving sustainable development goals (SDGs); however, it is gradually becoming a scarce resource due to pressure from both climatic and non-climatic factors. Understanding sources and extend of vulnerability of the water resources is the very frst step to design appropriate strategies aimed at securing water for various uses. This study therefore assessed vulnerability of water resources and its spatial distribution across the Palikas (new local governments) with Gulmi district in Province-5 as the case study. Vulnerability was assessed using an indicator-based framework comprising of two components and six sub-indices. Results showed that Musikot is the highly vulnerable Palika among the 12 Palikas, and Resunga is the least vulnerable. The results are useful for prioritizing the Palikas for allocating resources aimed at targeting new programs for reducing poverty and conserving natural resources.

Study region: Karnali-Mohana (KarMo) river basin, Western Nepal. Study focus: This study has developed a hydrological model using multi-site calibration approach for a large basin, the Karnali-Mohana (KarMo) in Western Nepal, which has a lot of potential for water resources development and contribute to the national prosperity. It further applies the model to characterize hydrology and water resources availability across spatio-temporal scales to enhance understanding on water availability and potential uses. The newly developed hydrological model in Soil and Water Assessment Tool (SWAT) is capable of reproducing the hydrological pattern, the average flows, and the flow duration curve at the outlet of the basin and five major sub-basins. New hydrological insights for this region: The model simulated results showed that about 34 % of average annual precipitation in the KarMo basin is lost as evapotranspiration, but with a large spatio-temporal heterogeneity. The Hills and Tarai are relatively wetter than the Mountains. The average annual flow volume at the basin outlet is estimated as 46,250 million-cubic-meters (MCM). The hydrological characterization made in this study are further used for climate change impact assessment (Part-B in the same journal), environmental flows assessment and evaluating trade-offs among various water development pathways, which are published elsewhere. This model, therefore, has potential to contribute for strategic planning and sustainable management of water resources to fuel the country’s prosperity.

Urbanisation will be one of the 21st centuryapos;s most transformative trends. By 2050, it will increase from 55% to 68%, more than doubling the urban population in South Asia and Sub-Saharan Africa. Urbanisation has multifarious (positive as well as negative) impacts on the wellbeing of humans and the environment. The 17 UN Sustainable Development Goals (SDGs) form the blueprint to achieve a sustainable future for all. Clean Water and Sanitation is a specific goal (SDG 6) within the suite of 17 interconnected goals. Here we provide an overview of some of the challenges that urbanisation poses in relation to SDG 6, especially in developing economies. Worldwide, several cities are on the verge of water crisis. Water distribution to informal settlements or slums in megacities (e.g. N50% population in the megacities of India) is essentially non-existent and limits access to adequate safe water supply. Besides due to poor sewer connectivity in the emerging economies, there is a heavy reliance on septic tanks, and other on-site sanitation (OSS) system and by 2030, 4.9 billion people are expected to rely on OSS. About 62–93% of the urban population in Vietnam, Sri Lanka, the Philippines and Indonesia rely on septic tanks, where septage treatment is rare. Globally, over 80% of wastewater is released to the environment without adequate treatment. About 11% of all irrigated croplands is irrigated with such untreated or poorly treated wastewater. In addition to acute and chronic health effects, this also results in significant pollution of often-limited surface and groundwater resources in Sub-Saharan Africa and Asia. Direct and indirect water reuse plays a key role in global water and food security. Here we offer several suggestions to mitigate water and food insecurity in emerging economies.

Streamflow alteration and subsequent change in long-term average, seasonality, and extremes (e.g., floods and droughts) may affect water security, which is a major concern in many watersheds across the globe. Both climatic and anthropogenic activities may contribute to such changes. Therefore, this study assesses: (i) Streamflow and precipitation trends to identify streamflow alterations in the Extended East Rapti (EER) watershed in central-southern Nepal; (ii) relationship of the alterations to climatic and anthropogenic sources; and (iii) implications of streamflow changes to the socio-environmental system. The trends in streamflow were analyzed for pre-and post-1990 periods considering the abrupt shift in temperature trend in 1990. Results showed a general decreasing trends in discharge post-1990 in the EER watershed. Human activities have significantly contributed in altering streamflow in the EER. Human-induced streamflow alterations have affected the water availability, food security, river health, aquatic biodiversity, and groundwater abstraction in the EER watershed.

Solar-powered irrigation pumps (SPIPs) have been promoted in the Eastern Gangetic Plains (EGP) in recent decades, but rates of adoption are low. This case study assesses the evidence from several solar pump business models being adopted in parts of the EGP, particularly eastern Nepal and northern India, and explores how different models perform in various contexts. It documents lessons for increasing farmers’ resilience to droughts through better groundwater use by promotion of SPIPs. Groundwater access for agriculture in the past was dependent on diesel and electric pumps, respectively constrained by costs and reliability of energy. Both government and nongovernment agencies have promoted SPIPs in the Ganges basin for irrigation and drinking purposes. SPIPs receive different levels of subsidies across countries and states in the region to facilitate adoption and ensure continuous and timely irrigation, which particularly benefits small and marginal farmers. Because the EGP faces variability in water availability, the SPIPs could help in building drought resilience. However, because low operating costs for SPIPs does little to incentivize farmers to use water efficiently, one critical question is how to balance equitable access to SPIPs while ensuring groundwater overdraft is not perpetuated. Farmers’ awareness of efficient water management options is crucial to avoid overextraction of groundwater.

Groundwater resources of Kathmandu Valley in Nepal are under immense pressure from multiple stresses, including climate change. Due to over-extraction, groundwater resources are depleting, leading to social, environmental and economic problems. Climate change might add additional pressure by altering groundwater recharge rates and availability of groundwater. Mapping groundwater resilience to climate change can aid in understanding the dynamics of groundwater systems, facilitating the development of strategies for sustainable groundwater management. Therefore, this study aims to analyse the impact of climate change on groundwater resources and mapping the groundwater resiliency of Kathmandu Valley under different climate change scenarios. The future climate projected using the climate data of RCMapos;s namely ACCESS-CSIRO-CCAM, CNRM-CM5- CSIRO-CCAM and MPI-ESM-LR-CSIRO-CCAM for three future periods: near future (2010–2039), mid future (2040–2069) and far future (2070–2099) under RCP 4.5 and RCP 8.5 scenarios were bias corrected and fed into the Soil and Water Assessment Tool (SWAT), a hydrological model, to estimate future groundwater recharge. The results showed a decrease in groundwater recharge in future ranging from 3.3 to 50.7 mm/yr under RCP 4.5 and 19–102.1 mm/yr under RCP 8.5 scenario. The GMS-MODFLOW model was employed to estimate the future groundwater level of Kathmandu Valley. The model revealed that the groundwater level is expected to decrease in future. Based on the results, a groundwater resiliency map of Kathmandu Valley was developed. The results suggest that groundwater in the northern and southern area of the valley are highly resilient to climate change compared to the central area. The results will be very useful in the formulation and implementation of adaptation strategies to offset the negative impacts of climate change on the groundwater resources of Kathmandu Valley.

Purpose: The need to increase women’s access to extension has been extensively discussed. This paper assesses women’s access to extension services through the Plantwise extension approach as a baseline for future comparison of women’s access through other extension approaches. It also assesses whether crops that men and women farmers seek plant health advice on are similar or not, and attempts to disperse assumptions that continue to be made about what crops women and men grow. Approach: We analysed data from the Plantwise Online Management System for 13 countries using descriptive and inferential statistics. Findings: We show that the Plantwise extension approach enables higher levels of women’s access than generally reported for agricultural extension, that the crops that women and men seek extension advice on is not gender dependent, and there are few clear distinctions between their crops of interest. Practical implications: There is limited literature studying gender inclusiveness in different extension approaches. The findings add to the documentation of assessing women’s access to demand-driven extension. Theoretical implications: Plantwise is a new extension approach which needs to be assessed from spatial and temporal perspectives to understand whether demand-driven extension enables increased women’s access over time. Originality/value: Extension service provision is often based on assumptions about what crops are being grown. Small studies have challenged these assumptions, but this large dataset enables us to test these assumptions more thoroughly across 13 countries adding to the weight of evidence against the existence of women’s and men’s crops.

Water diversion projects across the world, for drinking water, energy production and irrigation, have threatened riverine ecosystems and organisms inhabiting those systems. However, the impacts of such projects on aquatic biodiversity in monsoon-dominated river ecosystems are little known, particularly in Nepal. This study examines the effects of flow reduction due to water diversion projects on the macroinvertebrate communities in the rivers of the Karnali and Mahakali basins in the Western Himalayas in Nepal. Macroinvertebrates were sampled during post-monsoon (November), baseflow (February) and pre-monsoon (May) seasons during 2016 and 2017. Nonmetric Multidimensional Scaling (NMDS) was performed to visualize clustering of sites according to percentage of water abstractions (extraction of water for various uses) and Redundancy Analysis (RDA) was used to explore environmental variables that explained variation in macroinvertebrate community composition. A significant pattern of macroinvertebrates across the water abstraction categories was only revealed for the baseflow season. NMDS clustered sites into three clumps: “none to slight water abstraction (lt; 30% – Class 1)”, “moderate water abstraction (gt; 30% to lt; 80% – Class 2)” and “heavy water abstraction (gt; 80% – Class 3)”. The study also showed that water abstraction varied seasonally in the region (Wilk’s Lambda = 0.697, F(2, 28) = 4.215, P = 0.025, n2 = 0.23). The RDA plot indicated that taxa such as Acentrella sp., Paragenetina sp., Hydropsyche sp., Glossosomatinae, Elmidae, Orthocladiinae and Dimesiinae were rheophilic i.e. positively correlated with water velocity. Taxa like Torleya sp., Caenis sp., Cinygmina sp., Choroterpes sp., Limonidae and Ceratopogoniidae were found in sites with high proportion of pool sections and relative high temperature induced by flow reduction among the sites. Indicator taxonomic groups for Class 1, 2 and 3 water abstraction levels, measured through high relative abundance values, were Trichoptera, Coleoptera, Odonata and Lepidoptera, respectively. Macroinvertebrate abundance was found to be the more sensitive metric than taxonomic richness in the abstracted sites. It is important to understand the relationship between flow alterations induced by water abstractions and changes in macroinvertebrates composition in order to determine sustainable and sound management strategies for river ecosystems.

This working paper was produced under the European Union Horizon 2020 funded AGRUMIG project and traces the impact of Covid-19 on migration trends in seven project countries – China, Ethiopia, Kyrgyzstan, Moldova, Morocco, Nepal and Thailand. The context of global migration has changed dramatically due to the coronavirus pandemic. Both within and between countries there has been a substantial curtailment of movement. As a result of multiple lockdowns, economic activity has severely declined and labor markets have ground to a halt, with mass unemployment in industrialized economies looming on the horizon. For both migrant hosting and origin countries – some are substantially both – this poses a set of complex development challenges. Partners of the AGRUMIG project undertook a rapid review of impacts across project countries, exploring the impacts on rural households but also identifying the persistent desire to migrate in spite of restrictions.

This report explores how women perceive participation and empowerment vis-a-vis access to water and other agricultural resources in the Tarai/Madhesh of Nepal. The report argues that gendered vulnerability is indeed intricately connected with other axes of difference, such as caste and economic status, despite women’s critical role in agricultural production and their active engagement in access to water and irrigation in agriculture. Overall, women’s well-being seems to have decreased as a consequence of male out-migration. However, there are women who have also become empowered in new ways, taking up enterprise opportunities. The authors point out that at the level of policy and external development interventions, a dominating narrative on women’s limited participation in agriculture being a result of ‘social norms’ exists. Public irrigation agencies have used this myth to absolve themselves of the responsibility for ensuring gender equality in program implementation. The report concludes that strengthening equitable irrigation user groups alongside capacity building for farmers and program implementers are critical measures for improving women’s access to irrigation and overall well-being. Women should be ensured meaningful participation, including leadership roles. Finally, this report recommends linking irrigation user groups to other income-generation schemes, and facilitating access to better credit, finance and agricultural inputs.

The Ganga is an international transboundary river that flows across three major riparian countries: India, Nepal, and Bangladesh, where India shares a significant proportion of the total basin area. The river system is highly dynamic and regularly floods in all three countries due to abundant rainfall in a short period of only four months each year that causes tremendous loss of both property and human life. In this study, we have done a synoptic review to synthesize the hydrology, hydrogeology, and modeling studies that have analyzed hydrological changes and their impacts in the Ganga basin. This review also identifies some of the knowledge gaps and discusses possible options for enhancing the understanding of sustainable water development and management. This review indicated that transparent data sharing, use of satellite-based observations along with in-situ data, integrated hydro-economic modeling linked to reliable coupled surface–groundwater models, a central shared decision support center for early warning systems to deal with hydrological extremes, joint river commissions and monitoring teams, and multilateral water sharing treaties (agreements) are required to promote sustainable and equitable distribution of water resources and to avoid water sharing conflicts in the Ganga basin.

With the objective to provide a basis for regional climate models (RCMs) selection and ensemble generation for climate impact assessments, we perform the first ever analysis of climate projections for Western Nepal from 19 RCMs in the Coordinated Regional Downscaling Experiment for South Asia (CORDEX-SA). Using the climate futures (CF) framework, projected changes in annual total precipitation and average minimum/maximum temperature from the RCMs are classified into 18 CF matrices for two representative concentration pathways (RCPs: 4.5/8.5), three future time frames (2021–2045/2046–2070/2071–2095), three geographic regions (mountains/hills/plains) and three representative CF (low-risk/consensus/ high-risk). Ten plausible CF scenario ensembles were identified to assess future water availability in Karnali basin, the headwaters of the Ganges. Comparison of projections for the three regions with literature shows that spatial disaggregation possible using RCMs is important, as local values are often higher with higher variability than values for South Asia. Characterization of future climate using raw and bias-corrected data shows that RCM projections vary most between mountain and Tarai plains with increasing divergence for higher future and RCPs. Warmer temperatures, prolonged monsoon and sporadic rain events even in drier months are likely across all regions. Highest fluctuations in precipitation are projected for the hills and plains while highest changes in temperature are projected for the mountains. Trends in change in annual average discharge for the scenarios vary across the basin with both precipitation and temperature change influencing the hydrological cycle. CF matrices provide an accessible and simplified basis to systematically generate application-specific plausible climate scenario ensembles from all available RCMs for a rigorous impact assessment.

Basin-wide planning requires tools and strategies that allow comparison of alternative pathways and priorities at relevant spatial and temporal scales. In this paper, we apply a hydroeconomic model–the Western Nepal Energy Water Model–that better accounts for feedbacks between water and energy markets, to optimize water allocations across energy, agriculture, municipal, and environmental sectors. The model maximizes total economic benefits, accounting for trade-offs both within and across sectors. In Western Nepal, we find that surface water availability is generally sufficient to meet existing and growing demands in energy and agricultural sectors; however, expansion of water storage and irrigation infrastructure may limit environmental flows below levels needed to maintain the full integrity of important aquatic ecosystems. We also find substantial trade-offs between irrigation in Nepal and satisfaction of the institutional requirements implied by international water-use agreements with the downstream riparian India. Similar trade-offs do not exist with hydropower, however. Model results and allocations are sensitive to future domestic and international energy demands and valuations.

The term “environmental flows” refers to a combination of features, including quantity, quality, and timing of water flows required to sustainably maintain a river’s health, balancing both ecological and societal needs. Incorporating basic human livelihood and sociocultural aspects in environmental flow assessments alongside ecological concerns provides a more holistic perspective on water flow management. Here, we provide an assessment that complements an ecosystem functioning lens by focusing solely on quantifying the flows associated with livelihood activities and spiritual water requirements of local riparian communities in the Karnali basin in Western Nepal. This assessment is based on the first social survey related to environmental flows conducted in the Karnali basin. We collected data using mixed methods, including social surveys, key informant interviews, and focus group discussions, across six locations in the Karnali basin that provide us with a rich and dynamic perspective on the relationship between rivers and their surrounding communities, and the challenges faced by those communities. Among the subsistence and spiritual requirements of local communities are uses for activities that include drinking, small-scale irrigation, domestic needs, fishing, and ceremonial usage. All communities we visited most strongly associated the following activities with water flow variation: small-scale irrigation, fishing, ceremonial usage, domestic needs, and tourism. The water flows required for these key activities were quantified, and results from the six sites are presented in the form of a qualitative scale of minimum water levels (ranging across poor, acceptable, and ideal) required to meet vital local needs. The minimum acceptable water flow requirement to satisfy social criteria is just gt; 20% of the mean annual runoff at the visited locations. These requirements are particularly vital to consider, given ongoing efforts to tap the vast hydropower potential in Nepal through construction of major storage projects. Such projects would change the flow regime of affected rivers and potentially raise concerns that existing demands might be compromised.

Global discourses have advocated womenapos;s empowerment as a means to enhance food security. Our objective was to critically review the causal linkages between womenapos;s empowerment and food availability and access. We relied on mixed methods and a cross-country analysis, using household survey data from Bangladesh, Nepal and Tajikistan and qualitative data from Nepal. The quantitative analysis highlights the diversity of patterns linking empowerment and food security indicators and the roles socio-economic determinants play in shaping these patterns across countries. The qualitative analysis further stresses the need for a truly intersectional approach in food security programmes that supports challenging the structural barriers that keep marginalised men and women food insecure. Lastly, our findings call for informing standardised measures of empowerment with an assessment of local meanings and values.

Multiple-use water services (MUS) have been promoted and piloted globally for two decades as a socio-technical innovation. Yet the MUS approach has hardly extended beyond donor-funded projects to public policies. We use a collective action framework to analyze the non-institutionalization of MUS in Nepal. We find that MUS has much cognitive legitimacy, but discourse fragmentation has reduced its socio-political legitimacy. Yet the latter is essential to overcome the institutional challenges of a fragmented public water sector and to mainstream MUS into policy debate.

This paper investigates the spatial dimension of power relations and the shaping of local alliances through a hydropower development project in Nepal. It provides a grass-roots illustration on the role of space in shaping and reshaping power relations, and how it manifests in the formation of local strategic alliances. Taking the Upper Karnali hydropower project as a case study, the paper highlights: 1) the role of private sector actor as an ad-hoc decision maker in hydropower development in the country; 2) how hydropower development is perceived by those who will be most affected; and 3) how the two shape the localized dynamics in hydropower decision making, while also sheds light on some of the key gaps in hydropower decision-making landscape and processes. Viewing space as a process and a product of socio-political interface, it shows how local communities living along the Karnali River view the planned hydropower project differently, how these views are rooted in their relationship with the hydropower company, and how such relationship is predetermined by local communities’ bargaining power in relation to the proximity of their respective villages to the planned hydropower dam site, and vice versa. Unpacking the power relations shaping and reshaping spatial politics in hydropower decision making, it presents the concept of spatial alliances as a theoretical underpinning to unpack the question on why and how power relations emerge, are sustained and reproduced.

Though springs are the primary source of water for communities in the mid-hills of Nepal, an in-depth scientific understanding of spring systems is missing, preventing the design of effective climate-resilient interventions for long-term sustainability of springs. This study marks the first attempt to combine environmental isotopes analysis with hydrometric and hydrogeological measurements to identify dominant recharge zones for springs in two mountainous catchments—Banlek and Shikarpur—in Far-Western Nepal. In total, 422 water samples collected from rainfall, springs and streams between March 2016 and March 2017 were analyzed for their isotopic composition (d18O and dD). Isotopic composition of rainwater shows seasonality, suggesting that different sources of water vapor cause rains in monsoon and in dry season. Rainfall responses of individual springs were used to identify connections to unconfined and deeper groundwater strata. The isotopic composition of springs in the two catchments ranges from -9.55 to -8.06‰ for d18O and -67.58 to -53.51‰ for dD. The isotopic signature of the spring sources falls close to the local meteoric water line for the corresponding season, indicating strong rainfall contribution to springs. Altitudinal isotopic gradients suggest mean recharge elevation of 2,600–2,700 m asl for springs in Shikarpur, which lies beyond the surface-water catchment, and a recharge elevation of 1,000–1,100 m asl for Banlek, which partially extends beyond the surface-water catchment. The demarcated recharge zones will be used by government agencies to implement recharge interventions to increase the resiliency and reliability of springs in Far-Western Nepal.

Despite frequent calls for transformative approaches for engaging in agrarian change and water governance, we observe little change in everyday development and research praxis. Empirical studies on transformative engagements with gender relations among smallscale or tenant farmers and water user groups are particularly rare. We explore transformative engagements through an approach based on critical pedagogy (Freire, 1996) and transformative practice (Leder, 2018). We examine opportunities to promote empathy and critical consciousness on gender norms, roles and relations in agriculture and resource management. We developed and piloted an innovative “Participatory Gender Training for Community Groups” as part of two internationally funded water security projects. The training consists of three activities and three discussions to reflect on gender roles in families, communities and agriculture, to discuss the gendered division of labour and changing gender relations over time and space, and to create empathy and resolve conflicts through a bargaining role play with switched genders. The approach was implemented in twelve villages across four districts in Nepal and India (Bihar, West Bengal). Our results show how the training methods can provide an open space to discuss local gender roles within households, agriculture and natural resource management. Discussing own gender norms promotes critical consciousness that gender norms are socially constructed and change with age, class, caste and material and structural constraints such as limited access to water and land. The activities stimulated enthusiasm and inspiration to reflect on possible change towards more equal labor division and empathy towards those with weaker bargaining power. Facilitators have the most important role in transformative engagements and need to be trained to reinterpret training principles in local contexts, and to apply facilitation skills to focus on transforming rather than reproducing gender norms. We argue that the gender training methods can initiate transformative practice with the gender-water-agriculture nexus by raising critical consciousness of farmers, community mobilisers, and project staff on possibilities of social change “in situ”.

The Koshi Basin, spread across China, Nepal and India, is perceived as having high potential for hydropower and irrigation development, both seen as ways to promote economic development in the region. This paper quantifies and assesses the past and projected future spatial and temporal water balances in the Koshi Basin. Results show that precipitation and net water yield are lowest in the transmountain region and the Tibetan plateau. The values are highest in the mountain region, followed by the hills and Indo-Gangetic Plains. Approximately 65% of average annual precipitation is converted to flows, indicating high water availability. Actual evapotranspiration is highest in the Indo-Gangetic Plains region due to the presence of irrigated agriculture and a few forested mountain watersheds. As most of the water from the mountain and hill regions eventually flows down to the plains, the mountain and hill regions in Nepal are important for maintaining agriculture in the plains in both Nepal and India. Results from the flow analyses indicate the high temporal variability of flows in the basin. The frequent occurrences of both high- and low-flow events demonstrate the existing vulnerability of the region to both floods and droughts, leading to a very risk-prone livelihood system. Climate change projections show an increasing trend in precipitation and net water yield for most of the basin, except the transmountain region. Therefore, it is important to consider the climate change impacts on water resources in future planning.

To meet the demand deficit in Kathmandu Valley, the Government of Nepal has planned to supply an additional 510 million liters per day (mld) of water by implementing the Melamchi Water Supply Project (MWSP) in the near future. In this study, we aim to assess the spatial distribution of groundwater availability and pumping under five scenarios for before and after the implementation of the MWSP using a numerical groundwater flow model. The data on water demand, supply infrastructure, changes in hydraulic head, groundwater pumping rates, and aquifer characteristics were analyzed. Results showed that groundwater pumping from individual wells ranges from 0.0018 to 2.8 mld and the average hydraulic head declined from 2.57 m below ground level (bgl) (0.23 m/year) to 21.58 m bgl (1.96 m/year). Model simulations showed that changes in average hydraulic head ranged from þ2.83 m to þ5.48 m at various stages of the MWSP implementation, and 2.97 m for increased pumping rates with no implementation of the MWSP. Regulation in pumping such as monetary instruments (groundwater pricing) on the use of groundwater along with appropriate metering and monitoring of pumping amounts depending on the availability of new and existing public water supply could be interventions in the near future.

Kathmandu Upatyaka Khanepani Limited (KUKL) currently uses 35 surface and 57 groundwater sources to supply water for Nepal’s capital, Kathmandu. It is necessary to understand if the Melamchi Water Supply Project (MWSP) can assist lean period water supply by indirectly increasing groundwater storage, through diverting excess water supply to groundwater recharge zones. The current study analyzed long-term groundwater depletion to assess available groundwater storage, followed by assessment of groundwater balance for the Kathmandu Valley. Results show that total groundwater extraction for Kathmandu was 69.44 million cubic meters (MCM) and drawdown of the groundwater surface was 15–20 m since the construction of wells in 1984/85, indicating substantial overexploitation. Results indicate that the ongoing unmet demand of 170 MCM/year can be easily satisfied if groundwater storage is recharged effectively, as underground water storage potential is 246 MCM/year due to a groundwater depletion rate of 2–10 m. From results, it is evident that that the timely implementation of the MWSP can help ease ongoing water stress and aid in reversing the damage caused to groundwater storage. In the long run, MWSP can supply water and recharge groundwater during monsoon periods, thus improving the quality of life and socio-economic status in Kathmandu.

Himalayan river basin is marked by a complex topography with limited observational data. In the context of increasing extreme events, this study aims to characterize drought events in the Karnali River Basin (KRB). Firstly, historical data for 34-years (1981–2014) from ten different stations were analyzed to compute following drought indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI), Reconnaissance Drought Index (RDI), Self-Calibrated Palmer Drought Severity Index (sc-PDSI), Standardized Streamflow Index (SFI), and Palmer Hydrological Drought Severity Index (PHDI). Among them, SPI is able to capture the drought duration and intensity fairly well with the others. Secondly, SPI was used to analyse the drought of the entire basin. The SPI analysis showed occurrence of major drought events in the recent years: 1984–85, 1987–88, 1992–93, 1994–95, 2004–09, and 2012. The winter drought of 1999, 2006, 2008–09 were widespread and the monsoon drought is increasing its frequency. No particular pattern of drought was observed from the historical data; however, yield sensitivity index revealed that precipitation pattern and anomaly is influencing crop yield in the area. Being the first study revealing prevalence of the drought in KRB, it can provide a basis for prioritizing interventions focused on drought management in the region.

The Himalayas are highly susceptible to the impacts of climate change, as it consequently increases the vulnerability of downstream communities, livelihoods and ecosystems. Western Nepal currently holds significant potential as multiple opportunities for water development within the country are underway. However, it is also identified as one of the most vulnerable regions to climate change, with both an increase in the occurrence of natural disasters and exacerbated severity and impacts levels. Regional climate model (RCM) projections indicate warmer weather with higher variability in rainfall for this region. This paper combines bio-physical and social approaches to further study and understand the current climate shocks and responses present in Western Nepal. Data was collected from 3660 households across 122 primary sampling units across the Karnali, Mahakali and Mohana River basins along with focus group discussions, which provided a rich understanding of the currently perceived climatic shocks and related events. Further analysis of climatology was carried out through nine indices of precipitation and temperature that were found to be relevant to the discussed climate shocks. Results show that 79% of households reported experiencing at least one type of climate shock in the five-year period and the most common occurrence was droughts, which is also supported by the climate data. Disaggregated results show that perception varies with the region and among the basins. Analysis of climatic trends further show that irregular weather is most common in the hill region, although average reported frequency of irregular weather is higher in the mountain. Further analysis into the severity and response to climatic shocks suggest an imminent need for better adaptation strategies. This study’s results show that a vast majority of respondents lack proper access to knowledge and that successful adaptation strategies must be adapted to specific regions to meet communities’ local needs.

Despite decades of gender mainstreaming in the water sector, a wide gap between policy commitments and outcomes remains. This study aims at offering a fresh perspective on such policy gaps, by analysing how gendered discourses, institutions and professional culture contribute to policy gaps. We rely on a conceptual framework originally developed for analysing strategic change, which is used to analyse gender in the public water sector in Nepal. Our analysis relies on a review of national water policies and a series of semi-structured interviews with male and female water professionals from several public agencies. Our findings evidence how dominant discourses, formal rules and professional culture intersect to support and reproduce hegemonic masculine attitudes and practices of water professionals. Such attitudes and practices in turn favour a technocratic implementation of policy measures. We argue that gender equality policy initiatives in the water sector have overly focused on local level formal institutions and have not adequately considered the effects of masculine discourses, norms and culture to be effective in making progress towards gender equity. We conclude with policy recommendations.

Chamelia (catchment area = 1603 km2 ), a tributary of Mahakali, is a snow-fed watershed in Western Nepal. The watershed has 14 hydropower projects at various stages of development. This study simulated the current and future hydrological system of Chamelia using the Soil and Water Assessment Tool (SWAT). The model was calibrated for 2001–2007; validated for 2008–2013; and then applied to assess streamflow response to projected future climate scenarios. Multi-site calibration ensures that the model is capable of reproducing hydrological heterogeneity within the watershed. Current water balance above the Q120 hydrological station in the forms of precipitation, actual evapotranspiration (AET), and net water yield are 2469 mm, 381 mm and 1946 mm, respectively. Outputs of five Regional Climate Models (RCMs) under two representative concentration pathways (RCPs) for three future periods were considered for assessing climate change impacts. An ensemble of bias-corrected RCM projections showed that maximum temperature under RCP4.5 (RCP8.5) scenario for near-, mid-, and far-futures is projected to increase from the baseline by 0.9 C (1.1 C), 1.4 C (2.1 C), and 1.6 C (3.4 C), respectively. Minimum temperature for the same scenarios and future periods are projected to increase by 0.9 C (1.2 C), 1.6 C (2.5 C), and 2.0 C (3.9 C), respectively. Average annual precipitation under RCP4.5 (RCP8.5) scenario for near-, mid-, and far-futures are projected to increase by 10% (11%), 10% (15%), and 13% (15%), respectively. Based on the five RCMs considered, there is a high consensus for increase in temperature but higher uncertainty with respect to precipitations. Under these projected changes, average annual streamflow was simulated to increase gradually from the near to far future under both RCPs; for instance, by 8.2% in near-, 12.2% in mid-, and 15.0% in far-future under RCP4.5 scenarios. The results are useful for planning water infrastructure projects, in Chamelia and throughout the Mahakali basin, to ensure long-term sustainability under climate change.

Collective farming has been suggested as a potentially useful approach for reducing inequality and transforming peasant agriculture. In collectives, farmers pool land, labor, irrigation infrastructure, agricultural inputs and harvest to overcome resource constraints and to increase their bargaining power. Employing a feminist political ecology lens, we reflect on the extent to which collective farming enables marginalized groups to engage in smallholder agriculture. We examine the establishment of 18 farmer collectives by an action research project in the Eastern Gangetic Plains, a region characterised by fragmented and small landholdings and a high rate of marginalised and landless farmers. We analyze ambivalances of collective farming practices with regard to (1) social relations across scales, (2) intersectionality and (3) emotional attachment. Our results in Saptari/ Eastern Terai in Nepal, Madhubani/Bihar, and Cooch Behar/West Bengal in India demonstrate how intra-household, group and community relations and emotional attachments to the family and neighbors mediate the redistribution of labor, land, produce and capital. We find that unequal gender relations, intersected by class, age, ethnicity and caste, are reproduced in collective action, land tenure and water management, and argue that a critical feminist perspective can support a more reflective and relational understanding of collective farming processes. Our analysis demonstrates that feminist political ecology can complement commons studies by providing meaningful insights on ambivalences around approaches such as collective farming.

The twentieth century has seen a dramatic increase in human uses of and human impacts on water resources, increasing competition over water as well as depleting or deteriorating its availability. Given its importance to human life and livelihoods, water is becoming one of the major foci of environmental research. The coincidence of water scarcity with poverty in many parts of the world makes it a focal point of international development efforts. With engineering thinking dominating over past decades, water management research has embraced more integrative approaches triggered by an increasing awareness of failures that focused on narrow single issues or technical solutions to address the complex challenges of sustainable water management. This chapter explores whether, when, and how more inclusive framings might enable more socially relevant and impactful research, and lead to more effective action. Discussion begins by establishing what a frame is and then de ning what is meant by an “inclusive frame” for interdisciplinary research on environmental problems. Seven frames in water research are examined; emphasis is given to how framings are driven by differences in normative and theoretical positions, which yields very different views on progress and how best to achieve it. Next, the use of more inclusive frames in academic or research contexts is explored using two examples which incorporate multiple normative and theoretical positions. Barriers encountered by academics and researchers, as they attempt to use inclusive frames, are then examined. To explore how inclusive frames can be used to address real-world problems, three cases highlight the possibilities and challenges in applying inclusive frames to research with the goal of informing action and practice.

In the Ganges basin, 8268.6 km2 of irrigation command area is waterlogged following monsoon rains. In this study, vertical drain (VD) (L × D, 7 × 1 m) filled with drainage gravel (6.5 m) and coarse sand (0.5 m) is installed in farmer’s agricultural field to minimize the duration of seasonal waterlogging and tested in Mukundpur village, Vaishalli District, Bihar, India. At the experimental site, inundation of rainfall and runoff from surrounding areas along with the seepage from an earthen canal start in September and remain till February, every year which prevents timely planting of wheat in November-end/December. Drainage due to percolation and recharge to groundwater is constrained by 6.4-m thick clay layer, below 0.5-m root-zone, and the groundwater level, which rises to the surface level. VDs were installed to provide a path and allow inundated water to recharge the aquifer, as groundwater level recedes. Groundwater level drop, floodwater infiltration rate, groundwater discharge, and VD capability were estimated through field data. Results show that VDs connected the floodwater to groundwater and transferred the floodwater to the aquifer when groundwater level started to recede. The site was fully drained by the end of December, permitting farmers to plant wheat in January providing cool nights at germination, thus increasing yields.

Since the late 1990s, river basin planning has become a central idea in water resources management and a mainstream approach supported by international donors through their water programs globally. This article presents river basin planning as a function of power and contested arena of power struggles, where state actors create, sustain, and reproduce their bureaucratic power through the overall shaping of (imagined) bureaucratic territory. It argues that river basin planning is not an antidote to current ‘dysfunction’ in water resources management, rooted in overlapping jurisdictions, fragmented decision making, and bureaucratic competitions between various government agencies. On the contrary, it illustrates how river basin planning becomes a new ‘territorial frontier’, created and depicted by different government agencies as their envisioned operational boundary and as a means to sustain and increase their bureaucratic power and sectoral decision-making authority, amidst ongoing processes of federalism in Nepal.

Despite extensive literature on the complex nature of empowerment, current efforts to measure women’s empowerment in the agricultural development sector are largely limited to assessing visible forms of agency. We take a critical look at current efforts to measure women’s empowerment at the individual/household level through standardized tools. We examine the results of a household survey conducted in Nepal using the Women’s Empowerment in Agriculture Index (WEAI), which was developed as a monitoring and evaluation tool for the Feed the Future Initiative. Our interpretation of the results is informed by qualitative fieldwork conducted in the same region. In our quantitative analysis, we regress correlates of empowerment identified in the literature, such as age, education, household wealth, income, and household composition, on individual empowerment as measured by the WEAI. While several factors associated with women’s empowerment are significantly associated, household composition and intra-household relationships, which we expected to be essential factors in the local context, appear to be unrelated to the WEAI empowerment score. A measure of critical consciousness tested alongside the WEAI instrument appears instead to be closely associated with these factors. Our qualitative findings reveal that there is a discrepancy between local meanings of empowerment and definitions of empowerment defined in terms of agency. Based on these results, we suggest that improvements in measurement may be possible if approaches that measure power predominantly in terms of agency or decision-making were to include critical consciousness in their framework.

The response of any hydrological system to climate change may differ depending on characteristics of the system. Such studies are lacking for basins in Western Nepal. This paper, therefore, argues for a need to re-phrase the context of Western Nepal in more positive light and then analyses how a projected change in climate may impact on water availability of the region with a case of Chamelia watershed. A hydrological model in SWAT (Soil and Water Assessment Tool) environment is developed for the purpose. Future climate is projected using a set of fi ve Regional Circulation Models (RCMs). Then response of streamfl ow with projected change in climate is assessed. Results show the developed model performance is adequate to represent hydrological characteristics of the watershed. Future is projected to be warmer (high model consensus) and slightly wetter (more uncertainty), with winter and premonsoon season receiving more rainfall. Under the projected future changes, simulated stream fl ow is projected to change across future periods and seasons. The results are expected to be useful for future water resource and water infrastructure planning in the area.

Kathmandu Upatyaka Khanepani Limited (KUKL) has planned to harness water from outside the valley from Melamchi as an inter-basin project to supply water inside the ring road (core valley area) of the Kathmandu Valley (KV). The project, called the “Melamchi Water Supply Project (MWSP)”, is expected to have its first phase completed by the end of September 2018 and its second phase completed by the end of 2023 to supply 170 MLD (million liters a day) through the first phase and an additional 340 MLD through the second phase. The area has recently faced a severe water deficit and KUKL’s existing infrastructure has had a limited capability, supplying only 19% of the water that is demanded in its service areas during the dry season and 31% during the wet season. In this context, this study aims to assess the temporal trends and spatial distribution of household water security index (WSI), defined as a ratio of supply to demand for domestic water use for basic human water requirements (50 L per capita per day (lpcd)) and economic growth (135 lpcd) as demand in pre and post-MWSP scenarios. For this purpose, data on water demand and supply with infrastructure were used to map the spatial distribution of WSI and per capita water supply using ArcMap. Results show a severe water insecurity condition in the year 2017 in all KUKL service areas (SAs), which is likely to improve after completion of the MWSP. It is likely that recent distribution network and strategies may lead to inequality in water distribution within the SAs. This can possibly be addressed by expanding existing distribution networks and redistributing potable water, which can serve an additional 1.21 million people in the area. Service providers may have to develop strategies to strengthen a set of measures including improving water supply infrastructures, optimizing water loss, harnessing additional water from hills, and managing water within and outside the KUKL SAs in the long run to cover the entire KV.

Groundwater has been noted as a major resource for irrigation water in Nepal Terai. The development of different methods of groundwater withdrawal has been promoted in Rupandehi District. Open dug wells were a major source for domestic water use in the 1980s due to cost and ease of construction. But in later years, the promotion of tube wells, access to diesel pump sets, low yield and the deterioration of water quality from the open dug wells have caused a decline in usage and their abandonment in favor of shallow tube wells. This study was conducted in Mahuwari Village, Rupandehi District to assess the feasibility for the rehabilitation of abandoned open dug wells by reassessing access to irrigation water during the dry season, in areas with limited conductivity of aquifer hydrogeology. The yields of the wells were observed to be too low for large-scale irrigation, especially with the rice paddy cropping system. An assessment of well storage and recharge patterns offer an opportunity for off-season supplementary irrigation of home gardens for establishing vegetables and seedlings, with good water management practices. The potential yield of the open dug wells at the peak of the dry season was 4 m3 day-1 (0.44 mm-ha), suficient to irrigate 0.12 ha of a tomato ield, satisfying 25% of a currently fallowed field for home gardening.

This paper investigates the public participation (PP) process in environmental impact assessments (EIA) of three large-scale hydropower plants (HPs) in Nepal, and looks at how the process can be improved to include the interests of citizens impacted. It is the theoretical standpoint of this paper that improvements to the PP process can be implemented only within a given context, wherein the proponent (owner of the HP) allows sharing of decision making with citizens. By comparing the PP process as it is written in the Nepali EIA law, execution of it by proponents and citizen experience with its execution, discrepancies are identified and analyzed to ascertain the difficulties that are experienced and what this implies in terms of decision making. Recommendations for improving the PP process as experienced by citizens are proposed by seeking solutions to overcome the discrepancies identified and also through new methods and timing of PP.

Water security has become the new buzzword for water and development programmes in the rural South. The concept has potential to focus policymakers and practitioners on the inequalities and injustices that lie behind lack of access to affordable, safe, and clean water. The concept of women’s empowerment also provides an opportunity to do this. However, the vast majority of water security interventions using the term are apolitically and technically framed and fail to understand complex intersectional inequalities. We suspect that many of these interventions have been implemented following a business-as-usual approach with the risk of reproducing and even exacerbating existing gendered inequalities in access to and control over water. This article explores these concerns in the context of four villages in Western Nepal, where two internationally funded programmes aimed to empower women by improving access to water for both domestic and productive uses. They hoped to transform women into rural entrepreneurs and grassroots leaders. However, differences between women – such as age, marital status, caste, remittance flow, and land ownership – led to some women benefiting more than others. Water programmes must recognise and address difference between women if the poorest and most disadvantaged women are to benefit. Gender mainstreaming in the water sector needs to update its understanding of women’s empowerment in line with current feminist understandings of it as a processual, relational, and multi-dimensional concept. This means focusing on inter-household relations within communities, as well as intra-household relations. In addition, we recommend that water security programmes rely on more nuanced and context-specific understandings of women’s empowerment that go beyond enhanced access to resources and opportunities to develop agency to include social networks, critical consciousness, and values.

This Research Report presents the first comprehensive overview of the multiple climate hazard risks, and the proposed key issues and challenges facing the South Asian region. This report suggests methods for mapping such risks and estimating their impacts on people and agriculture in South Asia. Regional, country-wise and sub-national assessment of five climate-related risks – floods, droughts, extreme rainfall, extreme temperature and sea-level rise – is carried out. The approach involves overlaying climate hazard, sensitivity and adaptive capacity maps, and follows the vulnerability assessment framework of the Intergovernmental Panel on Climate Change (IPCC). A combined index based on hazard, exposure and adaptive capacity is introduced to identify areas susceptible to extreme risk. There is a lack of a systematic and comprehensive risk assessment capturing multiple climate hazards for the entire South Asian region and the need for a common framework for risk assessment. While this approach is well grounded in theories and integration of various spatial data including remote sensing data to derive hazard information, there is a clear need for linking additional elements from the ground at a finer scale among various sectors in developing comprehensive risk assessment information for a disaster risk management plan and promoting risk financing strategies.

Runoff generated in the monsoon months in the upstream parts of the Ganges River basin (GRB) contributes substantially to downstream floods, while water shortages in the dry months affect agricultural production in the basin. This paper examines the potential for subsurface storage (SSS) in the Ganges basin to mitigate floods in the downstream areas and increase the availability of water during drier months. The Soil and Water Assessment Tool (SWAT) is used to estimate “sub-basin” water availability. The water availability estimated is then compared with the sub-basinwise unmet water demand for agriculture. Hydrological analysis reveals that some of the unmet water demand in the subbasin can be met provided it is possible to capture the runoff in sub-surface storage during the monsoon season (June to September). Some of the groundwater recharge is returned to the stream as baseflow and has the potential to increase dry season river flows. To examine the impacts of groundwater recharge on flood inundation and flows in the dry season (October to May), two groundwater recharge scenarios are tested in the Ramganga sub-basin. Increasing groundwater recharge by 35 and 65 % of the current level would increase the baseflow during the dry season by 1.46 billion m3 (34.5 % of the baseline) and 3.01 billion m3 (71.3 % of the baseline), respectively. Analysis of pumping scenarios indicates that 80 000 to 112 000 ha of additional wheat area can be irrigated in the Ramganga sub-basin by additional SSS without reducing the current baseflow volumes. Augmenting SSS reduces the peak flow and flood inundated areas in Ramganga (by up to 13.0 % for the 65 % scenario compared to the baseline), indicating the effectiveness of SSS in reducing areas inundated under floods in the sub-basin. However, this may not be sufficient to effectively control the flood in the downstream areas of the GRB, such as in the state of Bihar (prone to floods), which receives a total flow of 277 billion m3 from upstream sub-basins.

Using biophysical and social analysis methods, this paper evaluated agricultural practices under changing climate in the Koshi Basin and assessed adaptation options. Agricultural trend analysis showed that in the recent three to four decades, the total cultivated area had declined in all parts of the basin except in the Nepal Mountain Region. Household survey results also confirmed such decline and further revealed shifts towards non-agricultural activities. Climate trend analysis showed changes in the frequency of wet and dry days in study districts, implying an increasing chance of flood and drought events. Household surveys further revealed that, in general, people perceived a decline in agricultural water availability and an increase in drought and flood events. The direct impacts of these changes were reduced crop yield, increased fallow lands, displacement of people from settlement areas, sedimentation of cultivable land and damage to properties. Household surveys showed that despite the perceived impacts on agriculture and livelihoods, only limited adaptation options are currently practised. Adaptation efforts are constrained by several factors, including: finance; technical knowledge; lack of awareness about adaptation options; lack of collective action; unclear property rights; and ineffective role of state agencies.

Study region: Kathmandu Valley, Capital city of Nepal. Study focus: This study applied three hydrological models (i.e., SWAT, HBV, and BTOPMC) to analyze the water balance components and their temporal and seasonal variations in the Kathmandu Valley, Nepal. The water balance components were investigated using the same precipitation, climatic data, and potential evapotranspiration (PET) as input variables for each model. The yearly and seasonal variations in each component and the interactions among them were analyzed. There was a close agreement between the monthly observed and calibrated runoff at the watershed scale, and all the three models captured well the flow patterns for most of the seasons. New hydrological insights for the region: The average annual runoff in the study watershed calculated by the SWAT, HBV, and BTOPMC models was 887, 834, and 865 mm, corresponding to 59%, 55%, and 57% of the annual precipitation, respectively. The average annual evapotranspiration (ET) was 625, 623, and 718 mm, and the estimated yearly average total water storage (TWS) was 5, -35, and 29 mm, respectively. The long-term average TWS component was similar in all three models. ET had the lowest inter-annual variation and runoff had the greatest inter-annual variation in all models. Predictive analysis using the three models suggested a reasonable range for estimates of runoff, ET, and TWS. Although there was variation in the estimates among the different models, our results indicate a possible range of variation for those values, which is a useful finding for the short- and long-term planning of water resource development projects in the study area. The effects of historical water use, water stress, and climatic projections using multi-model water balance approaches offer a useful direction for future studies to enhance our understanding of anthropogenic effects in the Kathmandu Valley.

The Eastern Gangetic Plains of South Asia represents a peripheral region far from the centers of global capitalist production, and this is all the more apparent in Mithilanchal, a cultural domain spanning the Nepal/Bihar border. The agrarian structure can be considered ‘semi-feudal’ in character, dominated by landlordism and usury, and backed up by political and ideological processes. Paradoxically, Mithilanchal is also deeply integrated into the global capitalist market and represents a surplus labor pool for the urban centers of Western India as well as the Persian Gulf in a classic articulation between pre-capitalist and capitalist modes of production. A review of the changes in the agrarian structure over recent decades in the context of globalisation, out-migration and climate stress, shows that while landlordism remains entrenched, the relationship between the marginal and tenant farmer majority and the landed classes has changed, with the breakdown of ideological ties and reduced dependence on single landlords. The paper thus ends on a positive note, as the contemporary juncture represents an opportune moment for new avenues of political mobilization among the peasantry.

Water resources planning and management requires technical knowledge as well as social and environmental considerations and enabling environment for sustainable and equitable development. In this context, this paper highlights the Digo Jal Bikas project which is using a multi-disciplinary framework to generate science-based understanding required for sustainable irrigation development. The project is creating a knowledgebase including an inventory of irrigation and hydropower projects; water availability under current and future climatic conditions; environmental flows requirements for various types of river systems; tradeoff analysis of various water resources development scenarios; and water governance analysis. We present here how the project is generating such a multi-disciplinary knowledgebase that is key for promoting sustainable irrigation development in the Karnali-Mohana basin in the western Nepal.

This study is the first to assess land subsidence in the Kathmandu Valley, Nepal. Land subsidence simulations were based on a fully calibrated groundwater (GW) flow model developed using a coupled surface–subsurface modelling system. Subsidence is predicted to occur as a result of deep aquifer compaction due to excessive GW abstraction. The north and north-east areas at the periphery of the GW basin are hotspots for this subsidence. The estimated subsidence is most sensitive to changes in land cover within the recharge areas. The model shows the Melamchi water supply project assists in the control of subsidence to some extent. In the absence of land subsidence measurements, this paper highlights the location and the potential levels of the subsidence hazard which will be useful for hazard prevention management. Additionally, this work provides a basis to design field investigations, monitoring networks for land subsidence and upgrading the present GW monitoring network. Although the study has presented a preliminary analysis, a more comprehensive model inclusive of clay subsidence is required to address the subsidence vulnerability of the central densely populated core of the valley, which reflects the need for a comprehensive database of the hydrogeology in the valley.

Integrated Water Resources Management (IWRM) still stands today as one of the most influential governance models in the water sector. Whereas previous analyses of IWRM have focused on the effectiveness of the institutional models it embodies and on policy implementation gaps, we examine the meanings that IWRM discourses have given to water management issues and how these meanings have in turn supported certain policy choices, institutions and practices. We use discourse analysis to study IWRM discourses in Nepal, where IWRM was introduced as the guiding policy principle for water management more than a decade ago, but not yet operationalised. We argue that IWRM discourses have operated a discursive closure in policy debates, thereby limiting the range of policy and institutional choices perceived as politically possible. In particular, we found that the promotion of IWRM as an institutional holy grail has obscured critical issues of social (in) justice related to water resources development by promoting an apolitical and techno-managerial vision of water development, largely centralised and relying on expert knowledge. We defend the need to move away from institutional panaceas and towards deliberative processes that allow alternative voices, discourses and knowledge.

Women’s empowerment has been a key tenet of international water security programmes. Discourses on water envision that enhanced access to water resources can transform disempowered women into successful rural entrepreneurs. However, because such programmes often rely on simplistic representations of water, gender relations, and empowerment, they risk perpetuating and exacerbating gender inequalities.; Our study unpacks the storylines that drive water security interventions in the rural Global South, based on the case study of a donor-funded project in Nepal. The latter explicitly aimed at empowering women by improving their access to water for domestic and productive uses and by transforming women into rural entrepreneurs and grassroots leaders. We largely used qualitative methodologies, based on focus group discussions and semi-structured interviews with households and key informants. Fieldwork was conducted in two villages targeted by the programme located in two districts of Far-Western Nepal.; Our findings show that the gender myths and models that drive water security programmes, e.g. women as individual decision-makers and entrepreneurs, fail to adequately consider intra-household relationships and negotiations and the values that give meaning to women’s agency. Such programmes tend to perpetuate predominant gendered norms, practices and unequal power relationships within households and communities. We recommend that water security programmes rely on more nuanced and context-specific understandings of women’s empowerment that go beyond enhanced access to resources and agency to include knowledge, critical consciousness and values. It is also important that such initiatives involve men and women – rather than exclusively targeting women – and initiate critical reflections on gender roles and masculinities.

Although the Ganges River Basin (GRB) has abundant water resources, the seasonal monsoon causes a mismatch in water supply and demand, which creates severe water-related challenges for the people living in the basin, the rapidly growing economy and the environment. Addressing these increasing challenges will depend on how people manage the basin’s groundwater resources, on which the reliance will increase further due to limited prospects for additional surface storage development. This report assesses the potential of the Ganges Water Machine (GWM), a concept proposed 40 years ago, to meet the increasing water demand through groundwater, and mitigate the impacts of floods and droughts. The GWM provides additional subsurface storage (SSS) through the accelerated use of groundwater prior to the onset of the monsoon season, and subsequent recharging of this SSS through monsoon surface runoff. It was identified that there is potential to enhance SSS through managed aquifer recharge during the monsoon season, and to use solar energy for groundwater pumping, which is financially more viable than using diesel as practiced in many areas at present. The report further explores the limitations associated with water quality issues for pumping and recharge in the GRB, and discusses other related challenges, including availability of land for recharge structures and people’s willingness to increase the cropping intensity beyond the present level.

Groundwater quality is gaining more importance in groundwater management due to rapid growth in population, agriculture and industrial sectors worldwide. The goal of the present study is to evaluate the groundwater chemistry and to identify the geochemical processes governing the water chemistry in the shallow uncon ned and deeper con ned aquifers in the Eastern Ganges Basin using geochemical methods. Groundwater samples were analysed for major ions and metals (Fe, Mn, Zn, Cu, Pb and As). Shallow wells are found to have high pH, EC, TDS, Ca, Mg, Cl and SO4, and low HCO3/Cl ratio compared to the deep wells. However, the average concentration of Na, HCO3, NO 3, PO 4, F and Mn is not signi cantly varied with depth which indicates that the variation in the water chemistry between uncon ned and con ned aquifers is not only due to the natural processes but also indicates that surface contamination sources could have affected the water chemistry in the uncon ned aquifer. In the uncon ned aquifer, processes like wastewater in ltration, denitri cation, reverse ion exchange and mineral weathering govern the water chemistry. The water chemistry in the con ned aquifer is regulated by weathering of silicate and carbonate minerals and regional ow.

Planning adaptation strategies in response to climate change (CC) can be a daunting task, especially in regions such as the Koshi Basin in the Himalayas; where CC impacts are still uncertain. This paper recommends targeting adaptation strategies by focusing on changes in variability between the past and future climates at smaller scales. The Soil and Water Assessment Tool (SWAT) and the Indicators of Hydrologic Alteration (IHA) are used for analysis. Results show: (i) higher maximum precipitation during monsoon and post-monsoon, and lower maximum precipitation during winter; (ii) increase in precipitation and flows in the trans mountain region during all seasons, except for flows during monsoon; (iii) increase in post-monsoon precipitation and routed flow volumes; (iv) decrease in precipitation during winter and routed flow volumes in all the regions, except the trans mountain region; and (v) increase in frequency of high peak flows and decrease in baseflows.

Reviving the Ganges Water Machine (GWM), coined 40 years ago, is the most opportune solution for mitigating the impacts of recurrent droughts and floods in the Ganges River Basin in South Asia. GWM create subsurface storage (SSS) by pumping more groundwater from the aquifers before the monsoon for irrigation and other uses and recharge it during the monsoon. The present study uses fully processed and physically based numerical models, MODFLOW and SWAT, in a semi-coupled modelling framework to examine the technical feasibility of recharging the SSS. The aquifer was simulated as a two-layer system using hydrogeological and groundwater data, model was calibrated from 1999 to 2005 and validated from 2006 to 2010. It assesses the impacts of gradual increase of SSS in 10 years from the base year 2010 under two scenarios (increased rainfall or controlled pumping and recharge) to meet a potential unmet demand of 1.68 billion cubic meters (Bm3) in the Ramganga sub-basin with an area of 18,668 km2. The results show that 3–4 m of subsurface storage can be created by groundwater pumping of 0.25 Bm3/year by 2020. Under the controlled pumping and recharge scenario, groundwater recharge and river seepage could increase by 14% (4.21–4.80 Bm3) and 31% (1.10–1.44 Bm3), respectively. However, baseflow will decrease by 30% (0.18–0.12 Bm3) over the same time period. The results also show that recharge increased 44% (4.21–6.05 Bm3) under an increased rainfall scenario. Simultaneously, river seepage and baseflows would increase 36% (1.10–1.14 Bm3) and 11% (0.18–0.20 Bm3), respectively. A well-designed managed aquifer recharge program is required to eliminate the negative impact of river flows in the low flow season.

A large number of small- to medium-sized community ponds exist in most parts of the Terai region in Nepal. Such ponds could be a viable alternative for other forms of surface irrigation. But, with the lack of efficient management, many of these ponds remain underutilized. An effort was made to facilitate the rehabilitation of such a pond in a selected village of Rupandehi District in Western Terai region of Nepal. This paper aims to evaluate the changed water availability situation in post-monsoon seasons after the pond rehabilitation. The paper also evaluates the feasibility of such interventions especially focusing on the potential to provide additional water and improve agricultural productivity. Results showed small increases in quantifiable indicators such as water availability, cropping intensity, productivity and income. The new institutional setup improved water allocation, improved operation and maintenance, and increased social awareness among the people about the importance of underutilized water resources. The intervention has the potential to be replicated in similar contexts.

The Ganges River basin faces severe water challenges related to a mismatch between supply and demand. Although the basin has abundant surface water and groundwater resources, the seasonal monsoon causes a mismatch between supply and demand as well as flooding. Water availability and flood potential is high during the 3–4 months (June–September) of the monsoon season. Yet, the highest demands occur during the 8–9 months (October–May) of the non-monsoon period. Addressing this mismatch, which is likely to increase with increasing demand, requires substantial additional storage for both flood reduction and improvements in water supply. Due to hydrogeological, environmental, and social constraints, expansion of surface storage in the Ganges River basin is problematic. A range of interventions that focus more on the use of subsurface storage (SSS), and on the acceleration of surface–subsurface water exchange, has long been known as the Ganges Water Machine (GWM). The approach of the GWM for providing such SSS is through additional pumping and depleting of the groundwater resources prior to the onset of the monsoon season and recharging the SSS through monsoon surface runoff. An important condition for creating such SSS is the degree of unmet water demand. The paper shows that the potential unmet water demand ranging from 59 to 124 Bm3 year-1 exists under two different irrigation water use scenarios: (i) to increase irrigation in the Rabi (November–March) and hot weather (April–May) seasons in India, and the Aman (July–November) and Boro (December–May) seasons in Bangladesh, to the entire irrigable area, and (ii) to provide irrigation to Rabi and the hot weather season in India and the Aman and Boro seasons in Bangladesh to the entire cropped area. However, the potential for realizing the unmet irrigation demand is high only in 7 sub-basins in the northern and eastern parts, is moderate to low in 11 sub-basins in the middle, and has little or no potential in 4 sub-basins in the western part of the Ganges basin. Overall, a revived GWM plan has the potential to meet 45–84 Bm3year-1 of unmet water demand.

Deficit irrigation could be considered as one potential option to improve water productivity and obtain some level of assured income under water scarcity and drought conditions in Central Asia. This article investigates water productivity and economic returns to two varieties of potato crop under four different soilmoisture regimes in Uzbekistan. Results suggest that deficit irrigation may not be considered as an option to improve water productivity of potato crop, particularly when the deficit is high. However, deficit irrigation options could be still considered as a viable option to maintain food security and some assured farm income even under extreme drought conditions.

Findings: Result revealed that the market actors of supply chain are taking significant benefit of value addition due to more investment in value creation. Vertical coordination is completely absent and the existence of horizontal coordination is in fragile form. The functional strategies in the upstream as well as the market side are not properly matching with the preference of the downstream actors of supply chain. It is suggested that the supply chain activities should work with different functional strategies such as proper drying and storage of seed and production of preferred varieties to satisfy the need of end consumers.

Concerns over climate change and climatic variability are growing in South Asia because of the potential detrimental impacts of these phenomena on livelihoods. Such growing concerns demonstrate a need to assess how farmers simultaneously cope with extreme events and adapt to climatic variability. Based on household surveys of 2660 farm families conducted in Nepal’s Terai, coastal Bangladesh, and the Indian state of Bihar, this paper seeks to (1) explore farmers’ coping strategies under adverse weather events; (2) identify key adaptation measures used by farmers; and (3) explore the policy interventions required to adjust agriculture to climatic variability. The study reveals that migration is the most important coping strategy of the households in Bihar and coastal Bangladesh, while reliance on credit markets is the most important in Terai. Farmers in the areas with higher rainfall variability pursue a higher number of coping strategies compared to farmers in areas with lower rainfall variability. Food available months are also higher in areas with higher rainfall variability. Across all sites, the most frequently mentioned adaptive practices are changing cropping patterns and adoption of resilient crop varieties. A large number of farmers place emphasis on breeding crop varieties that tolerate adverse weather. Governments should implement a number of planned activities to cope with adverse events, with the aim that these activities would be synergistic with adaptation to climate change.

On-site sanitation systems, such as septic tanks and pit latrines, are the predominant feature across rural and urban areas in most developing countries. However, their management is one of the most neglected sanitation challenges. While under the Millennium Development Goals (MDGs), the set-up of toilet systems received the most attention, business models for the sanitation service chain, including pit desludging, sludge transport, treatment and disposal or resource recovery, are only emerging. Based on the analysis of over 40 fecal sludge management (FSM) cases from Asia, Africa and Latin America, this report shows opportunities as well as bottlenecks that FSM is facing from an institutional and entrepreneurial perspective.

Many rural communities in Nepal experience considerable water stress during the dry season. Water storage systems (WSSs) have been proposed to supplement rain-fed irrigation and augment domestic water services in these communities. We evaluate household preferences for WSSs using a choice experiment and latent class modeling techniques. Results indicate the presence of three classes. The majority of households (E92%) belong to two equally-sized classes, a relatively privileged group (i.e. wealthier, better educated, etc.) with strong preferences for supplemental irrigation and a less privileged group that is mainly interested in improved domestic water services. The remaining class’ preferences are dominated by the cost attribute and are consistent with households facing severe cash constraints. Estimated welfare effects reveal that WSSs disproportionately benefit the privileged, although this disparity is mitigated with the provision of domestic water. These findings highlight the potential welfare gains from WSS investments, but stress the need for multi-purpose water resource development and the potential for elite capture.

Rural people in Nepal and other developing nations are part of complex, social-ecological systems. Efforts to provide assistance to these people must integrate knowledge from a variety of perspectives. This report documents the use of a role-playing game, supported by an agent-based model, to demonstrate the interaction between migration, social capital and the effectiveness of water storage. The importance of these interactions was highlighted by fieldwork conducted at several sites in the Koshi River Basin. The model underlying the game was a stylized representation based on the Indrawati Subbasin northeast of Kathmandu, Nepal. The report highlights that (a) role-playing tournaments can be an effective way to engage technical and policy experts with the complex interactions between the social and physical dimensions of watershed management; and (b) migration and the economic changes which drive these interactions are forces that need to be accepted, and investments in water storage need to be selected depending on how they fit into these trends.

Surface runoff generated in the monsoon months in the upstream parts of the Ganges River Basin contributes substantially to downstream floods, while water shortages in the dry months affect agricultural production in the basin. This paper examines the parts (sub-basins) of the Ganges that have the potential for augmenting subsurface storage (SSS), increase the availability of water for agriculture and other uses, and mitigate the floods in the downstream areas. The Soil and Water Assessment Tool (SWAT) is used to estimate sub-basin-wise water availability. The water availability estimated is then compared with the sub-basin-wise un-met water demand for agriculture. Hy-drological analyses revealed that five sub-basins produced more than 10 billion cubic meters (B m3) of annual surface runoff consistently during the simulation period. In these sub-basins, less than 50 % of the annual surface runoff is sufficient to irrigate all irrigable land in both the Rabi (November to March) and summer (April to May) seasons. Further, for most of the sub-basins, there is sufficient water to meet the un-met water demand, provided that it is possible to capture the surface runoff during the wet season. It is estimated that the average flow to Bihar State from the upstream of the Ganges, a downstream basin location, is 277 121 B m3, which is more than double the rainfall in the state alone. Strong relationships between outflows from the upstream sub-basins and the inflows to Bihar State suggested that flood inundation in the state could be reduced by capturing a portion of the upstream flows during the peak runoff periods.

The Ganges River Basin may have a major pending water crisis. Although the basin has abundant surface water and groundwater resources, the seasonal monsoon causes a mismatch between supply and demand as well as flooding. Water availability and flood potential is high during the 3–4 months of the monsoon season. Yet, the highest demands occur during the 8–9 months of the non-monsoon period. Addressing this mismatch requires substantial additional storage for both flood reduction and improvements in water supply. Due to hydrogeological, environmental, and social constraints, expansion of surface storage in the Ganges River Basin is problematic. A range of in- terventions that focus more on the use of subsurface storage (SSS), and on the acceleration of surface–subsurface water exchange, have long been known as the “Ganges Water Machine”. One approach for providing such SSS is through additional pumping prior to the onset of the monsoon season. An important necessary condition for creating such SSS is the degree of unmet water demand. This paper highlights that an unmet water demand ranging from 59 to 119 Bm3 exists under two different irrigation water use scenarios: (i) to increase Rabi and hot weather season irrigation to the entire irrigable area, and (ii) to provide Rabi and hot weather season irrigation to the entire cropped area. This paper shows that SSS can enhance water supply, and provide benefits for irrigation and other water use sectors. In addition, it can buffer the inherent variability in water supply and mitigate extreme flooding, especially in the downstream parts of the basin. It can also increase river flow during low-flow months via baseflow or enable the re-allocation of irrigation canal water. Importantly, SSS can mitigate the negative effects of both flooding and water scarcity in the same year, which often affects the most vulnerable segments of society – women and children, the poor and other disadvantaged social groups.

The concept of ‘Underground Taming of Floods for Irrigation’ (UTFI) is introduced as an approach for co-managing floods and droughts at the river basin scale. UTFI involves strategic recharge of aquifers upstream during periods of high flow, thereby preventing local and downstream flooding, and simultaneously providing additional groundwater for irrigation during the dry season for livelihood improvement. Three key stages in moving UTFI from the concept stage to mainstream implementation are discussed. An analysis of prospects in the Ganges River Basin are revealed from the earliest stage of mapping of suitability at the watershed level through to the latest stages of identifying and setting up the first pilot trial in the Upper Ganges, where a comprehensive evaluation is under way. If UTFI can be verified then there is enormous potential to apply it to address climate change adaptation/mitigation and disaster risk reduction challenges globally.

Integrated water resources management (IWRM) has been prescribed in the global water policy literature for decades. This article looks at how the concept has been applied in Nepal. It highlights the normative approach in IWRM policy formulation, the existing institutional barriers to apply it and how these resulted in the framing of IWRM ‘implementation’ as merely a compilation of donor-funded projects. Current discourse on IWRM highlights the need to shift the emphasis from national policy formulation to local adaptive, pragmatic approaches to IWRM. This article brings to light the need to identify potential entry points to scale up locally rooted water management approaches towards the development of nested institutional set-ups in water resources management.

Changes in the earthapos;s climate may have major impacts on plant regeneration. It is hence necessary to understand the link between germination and environmental cues. This study investigates the influence of climate change on germination response of eight crop species for the identification of species vulnerability to projected climate change. Data from the germination experiments were used to calibrate the germination module of the mechanistic model TACA-GEM in order to evaluate species germination vulnerability to a range of climate change scenarios expected to take place by the 2050s. The study was conducted for three sites of the Koshi river basin, Nepal. The findings indicate that rainfall is one of the primary factors influencing species germination. The projected moderate rainfall with warm climate benefitted germination in Saptari while the higher rainfall and colder climate projected for Bhojpur was adverse to the germination of most of the species. The germination response displayed by wheat and chickpea suggests that these species are the most resilient to projected climatic conditions. The study successfully demonstrated the influence of projected climatic conditions on species germination timing and success, reflecting species vulnerability to a range of climate conditions.

The Soil and Water Assessment Tool (SWAT) was used to simulate water balances in different cropping patterns under current and future climates in West Seti river Sub-basin, which is located in the far western region of Nepal. The results show that total precipitation over rice, maize, millet, wheat and barley fields were 1002, 818, 788, 186 and 169 mm respectively, whereas total simulated actual evapo transpiration (ET) are 534, 452, 322, 138 and 177 mm respectively under current climate. Actual ET will change by-1.9% in rice, -1.1% in maize, -2.0% in millet, +6.7% in wheat and +5.4% in barley under future climate projections. Results show that yield of maize and millet will decrease by 5.9% and 8.0% whereas yield of rice, wheat and barley will increase by 1.2%, 6.6% and 7.0% respectively. Therefore, the impact of climate change shows that summer crop yields will decrease except of rice and winter crop yields will increase. In general, a result of watersheds interventions shows that the crop yields will increase after the watershed interventions.

Background Chloroquine combined with primaquine has been the ecommended antimalarial treatment of Plasmodium vivax malaria infections for six decades but the efficacy of this treatment regimen is threatened by chloroquine resistance (CQR). Single nucleotide polymorphisms (SNPs) in the multidrug resistance gene, Pvmdr1 are putative determinants of CQR but the extent of their emergence at population level remains to be explored. Objective In this study we describe the prevalence of SNPs in the Pvmdr1 among samples collected in seven P. vivax endemic countries and we looked for molecular evidence of drug selection by characterising polymorphism at microsatellite (MS) loci flanking the Pvmdr1 gene. Methods We examined the prevalence of SNPs in the Pvmdr1 gene among 267 samples collected from Pakistan, Afghanistan, Sri Lanka, Nepal, Sudan, Sao Tome and Ecuador. We measured and diversity in four microsatellite (MS) markers flanking the Pvmdr1 gene to look evidence of selection on mutant alleles. Results SNP polymorphism in the Pvmdr1 gene was largely confined to codons T958M, Y976F and F1076L. Only 2.4% of samples were wildtype at all three codons (TYF, n = 5), 13.3% (n =28) of the samples were single mutant MYF, 63.0% of samples (n = 133) were double mutant MYL, and 21.3%(n = 45) were triple mutant MFL. Clear geographic differences in the prevalence of these Pvmdr mutation combinations were observed. Significant linkage disequilibrium (LD) between Pvmdr1 and MS alleles was found in populations sampled in Ecuador, Nepal and Sri Lanka, while significant LD between Pvmdr1 and the combined 4 MS locus haplotype was only seen in Ecuador and Sri Lanka. When combining the 5 loci, high level diversity, measured as expected heterozygosity (He), was seen in the complete sample set (He = 0.99), while He estimates for individual loci ranged from 0.00–0.93. Although Pvmdr1 haplotypes were not consistently associated with specific flanking MS alleles, there was significant differentiation between geographic sites which could indicate directional selection through local drug pressure. Conclusions Our observations suggest that Pvmdr1 mutations emerged independently on multiple occasions even within the same population. In Sri Lanka population analysis at multiple sites showed evidence of local selection and geographical dispersal of Pvmdr1 mutations between sites.

Water resources of the Koshi Basin (87,311km2) are largely untapped, and while proposals for their development exist, their impacts on current and future water demands are not quantified. The current study is the first to evaluate the impacts of 11 proposed development projects on hydropower generation and water storage. Results revealed that 29733GWh hydropower can be generated and 8382Million m3 (MCM) of water can be stored annually. This can satisfy unmet demands in current (660MCM) basin situation and future scenarios - i.e. population, agricultural and industrial growth – that are projected to have 920, 970 and 1003MCM unmet-demands, respectively by 2050.

Water has been identified as a key resource for Nepalapos;s economic growth. Although the country has 225 billion cubic meters of water available annually, less than 7% has been utilized. Climate change is a frequent topic in national development discussions in part because of its possible impact on future water availability. This study assessed the likely impact of climate change on water resources development in the Koshi River basin, Nepal, using the Soil and Water Assessment Tool to generate projections for the 2030s and 2050s. Results suggested that the impacts are likely to be scale dependent. Little impact is projected at annual, full-basin scales; but at sub-basin scale, under both the IPCCapos;s A2 and B1 scenarios, precipitation is projected to increase in the upper transmountain subwatersheds in the 2030s and in most of the basin in the 2050s and to decrease in the lower sub-basins in the 2030s. Water yield is projected to increase in most of the basin except for the A2 scenario for the 2030s. Flow volumes are projected to increase during the monsoon and postmonsoon but decrease during the winter and premonsoon seasons. The impacts of climate change are likely to be higher during certain seasons and in some sub-basins. Thus, if infrastructure is in place that makes it possible to store and transfer water as needed, the water deficit due to any changes in rainfall or flow patterns could be managed and would not be a constraint on water resources development. The risks associated with extreme events such as floods and droughts should, however, also be considered during planning.

Hydrological modeling is an indispensable component of water resources research and management in large river basins. There is a tendency for each new group working in a basin to develop their own model, resulting in a plethora of such tools for each major basin. The question then becomes: how much modeling is enough? This study reviews hydrological modeling in four large basins (Nile, Mekong, Ganges and Indus). Based on this review, four areas for action to improve effectiveness and reduce duplication in hydrological modeling of large basins are suggested. Model setups and input data, as well as model results, should be published, to allow more coordinated approaches and capitalize on past modeling efforts. More focus is needed on reporting uncertainty, to allow more realistic assessment of the degree of confidence in using results for policy and management. Initiatives are needed to improve the quantity and quality of data for model input, calibration and validation, both traditional hydrological monitoring (improved networks, expansion of automated systems) and new methods for data collection (remote sensing, crowd-sourcing and community based observations). Finally, within each major basin, an appropriate agency should be identified and resourced to take responsibility for data sharing and coordination, to reduce redundancy of effort and promote collaboration.

Over recent decades, there has been a shift in the focus of government irrigation schemes towards groundwater development throughout the Gangetic Plains, especially in the Nepal Tarai-Madhesh. This report explores the impact of landlord-tenant relations on access to groundwater irrigation. Tenant farmers have a reduced incentive to invest in pumping equipment and the boring of tube wells due to the high cost involved, insecure tenure and high rent payments, while landlords themselves have been shown to offer little support. The report suggests that it is crucial that policymakers are aware of the challenges posed by landlordism today in the Tarai and elsewhere in the Gangetic Plains, and remain engaged in debates over land reform. There are also a number of initiatives which could facilitate more equitable access to groundwater, which include allowing tenants without legal papers to apply for groundwater irrigation, systems for collective ownership of equipment, and greater targeting of programs and policies towards the tenant farmer class.

Background: Even though Plasmodium vivax has the widest worldwide distribution of the human malaria species and imposes a serious impact on global public health, the investigation of genetic diversity in this species has been limited in comparison to Plasmodium falciparum. Markers of genetic diversity are vital to the evaluation of drug and vaccine efficacy, tracking of P. vivax outbreaks, and assessing geographical differentiation between parasite populations. Methods: The genetic diversity of eight P. vivax populations (n = 543) was investigated by using two microsatellites (MS), m1501 and m3502, chosen because of their seven and eight base-pair (bp) repeat lengths, respectively. These were compared with published data of the same loci from six other P. vivax populations. Results: In total, 1,440 P. vivax samples from 14 countries on three continents were compared. There was highest heterozygosity within Asian populations, where expected heterozygosity (He) was 0.92-0.98, and alleles with a high repeat number were more common. Pairwise FST revealed significant differentiation between most P. vivax populations, with the highest divergence found between Asian and South American populations, yet the majority of the diversity (~89%) was found to exist within rather than between populations. Conclusions: The MS markers used were informative in both global and local P. vivax population comparisons and their seven and eight bp repeat length facilitated population comparison using data from independent studies. A complex spatial pattern of MS polymorphisms among global P. vivax populations was observed which has potential utility in future epidemiological studies of the P. vivax parasite.

Debates over the effectiveness of foreign aid have been recently revived both in the development sector and in the academia. International funding agencies have notably adopted new principles to improve aid delivery. Using the particular case study of a set of irrigation interventions in Western Nepal, we argue that these steps will not radically improve the pro-poor outcomes of aid interventions as long as the latter are framed in an apolitical, technical and managerial vision and discourse of development. We propose to adopt social and environmental justice as an analytical framework and vocabulary for action.

As climate change becomes accepted as a reality in the scientific community, it is critical to continue to understand its impact on the ground, particularly for communities dependent on agriculture and natural resources. This report reviews the extensive literature on the vulnerability to climate change in South Asia, with a focus on gender. It highlights how vulnerability is intricately connected to existing social structures. With respects to gender inequalities, the report reviews how men and women are affected in different ways by climate shocks, while differing access to resources and cultural ideologies mean that their capacity to ‘adapt’ is also not equal. The report also notes the importance of other axes of inequality (caste, class and ethnicity) in shaping gendered vulnerability. It concludes by offering insights into potential ways forward to promote more equitable adaptation to change through improved policies and practices.

This article examines community-driven multiple use water services (MUS) as pioneered by the Rural Village Water Resources Management Project (RVWRMP) in the Far and Mid-Western development regions of Nepal. These regions are characterised by poverty, remoteness, rugged terrain, food insecurity, water scarcity, and post-conflict legacy. Water provision for domestic and productive uses provides opportunities to address poverty and livelihoods in environments with highly decentralised governance. This study explores the first-hand lessons learned in the RVWRMP in Nepal since 2006. This project is embedded within the local government. Key project entry points are decentralisation, participation and empowerment. This article reflects how the community-managed systems are used for multiple uses whether they were designed for it or not. It focuses on household- and community-level changes and related institution building and participatory planning through Water Use Master Plans and a Step-by-Step approach. Recommendations are made for scaling up multiple use services.

Climate change could have a critical impact on agriculture in Nepal due to dry-season water shortages, and changes in the variability of water availability and associated uncertainty. This makes water storage systems (most notably ponds and tanks) increasingly important. This report explores the potential role of small-scale water storage infrastructure in two subbasins within the larger Koshi River Basin in central and eastern Nepal, yet shows that upscaling such infrastructure requires an appreciation of the other drivers of change in agriculture aside from climate (e.g., rising cost of living and poor terms of trade for agriculture). It also identifies the social relations and dynamics (distribution of land, water and labor) which could mediate the success of future interventions. It is clear from the research that, while small-scale water storage has the potential to significantly strengthen livelihoods in the Nepali hills, it is necessary to tailor projects to the existing political-economic context.

In recent years, the Government of Nepal has increased the amount of revenue it collects from hydropower operations and then distributes among districts and regions of the country. Larger, wealthier districts, which receive larger amounts of general revenues from the central government, also receive larger allocations of hydropower revenues. The per capita shares of hydropower revenue are notably larger in the Central andWestern Regions, which are home to most of Nepal’s hydropower facilities. Thus, the revenue sharing program does not favor poorer districts and regions with little hydropower development. Further, the hydropower revenue allocations to all development regions are small portions of the general revenues they receive. Consequently, the program is unlikely to have a substantial impact on economic development in poorer districts and regions.

This paper reviews the complex impact of climate change on gender relations and associated vulnerability on the Eastern Gangetic Plains of Nepal and India. Field research has identified that gendered vulnerability to climate change is intricately connected to local and macro level political economic processes. Rather than being a single driver of change, climate is one among several stresses on agriculture, alongside a broader set of non-climatic processes. While these pressures are linked to large scale political–economic processes, the response on the ground is mediated by the local level relations of class and caste, creating stratified patterns of vulnerability. The primary form of gendered vulnerability in the context of agrarian stress emerges from male out-migration, which has affected the distribution of labour and resources. While migration occurs amongst all socio-economic groups, women from marginal farmer and tenant households are most vulnerable. While the causes of migration are only indirectly associated with climate change, migration itself is rendering women who are left behind from marginal households, more vulnerable to ecological shocks such as droughts due to the sporadic flow of income and their reduced capacity for investment in off-farm activities. It is clear that policies and initiatives to address climate change in stratified social formations such as the Eastern Gangetic Plains, will be ineffective without addressing the deeper structural intersections between class, caste and gender.

Impact of climate change on the hydrology of the Ganges River Basin (GRB) is simulated by using a hydrological model – Soil and Water Assessment Tool (SWAT). Climate data from the GCM, Hadley Centre Coupled Model, version 3 (HadCM3) was downscaled with PRECIS for the GRB under A1B Special Report on Emission Scenarios (SRES) scenarios. The annual average precipitation will increase by 2.2% and 14.1% by 2030 and 2050, respectively, compared to the baseline period (1981–2010). Spatial distribution of the future precipitation shows that in the substantial areas of the middle part of the GRB, the annual precipitation in 2030 and 2050 will be reduced compared to the baseline period. Simulations indicate that in 2050 the total groundwater recharge would increase by 12%, while the increase of evapotranspiration will be about 10% compared to the baseline period. The water yield is also expected to increase in the future (up to 40% by 2050 compared to baseline), especially during the wetter months. The model setup is available for free from IWMI’s modelling inventory.

Exposure to arsenic and the use of arsenic-contaminated groundwater in agriculture causes serious health issues. Complete or partial contamination of groundwater is reported worldwide, especially in the Eastern Gangetic Basin (EGB). This study aims to create an overall assessment of arsenic contamination in the EGB based on existing literature, demarcate the extent of the affected area, highlight the impacts on the food chain and human health, and hopes the research will help in the better planning and management of groundwater. Although several studies have evaluated arsenic contamination of groundwater in the EGB, (a) there is no proper long-term monitoring being done in affected areas; (b) there is a debate to identify the exact source and transport processes of arsenic occurrence in this region; (c) there is no comprehensive method to estimate the level of arsenic contamination in soil, water and the food chain; and (d) Arsenic contamination in Bihar and Nepal is not evaluated systematically, especially arsenic accumulation in the food chain and human health issues. Data scarcity and accessibility are the major challenges in this region. Thus, this review recommends systematic monitoring and analysis of arsenic contamination in groundwater, soils and food across the EGB.

The Indus and Ganges river basins (collectively called the Indus-Ganges Basin) in South Asia covers 2.20 million km2 and is inhabited by a population of more than a billion people, many living in poverty with livelihoods based on waterdependent agriculture. The northwestern Indus basin is highly developed and over-abstracted with only about 10 % net river discharge; whereas in the eastern Ganges basin 37 % of the total precipitation discharges into the Bay of Bengal. The upper reaches of the basin are in the high Himalayas and seriously influenced by the melting of snow and glaciers and impending climate change. The average land and water productivity for the predominant rice-wheat cropping system is low with only about 5 per cent of the basin in the northwest (a regional “bright-spot”) having high productivity that is central to South Asia’s food security. This region is, however, now at risk of groundwater over-exploitation, aggravated mainly by energy and food policies. Access to water resources is relatively low in large areas and critical irrigation water requirements remain unmet due to inadequate access to the resource, high energy prices for water pumping, transboundary nature of the basin, and lack of an organized basin development plan. There is a strong linkage between poverty and low water productivity. Reduction of pervasive rural poverty in the basin can be accelerated by providing access to water to help achieve improvement in productivity, diversification and other pro-poor livelihoods. Based on the hydrological, agricultural and socio-economic variations in the two basins, as summarized in this chapter, the development frameworks and policies need to be regionally differentiated. Pathways to alleviate poverty might include improving agricultural productivity through optimal use of the available water resources, out-scaling bright-spot management practices to other parts of the basin, improved access to groundwater through affordable energy and cooperative tubewells for the smallholders, and policy and investment tools leading to land consolidation, rural infrastructure improvement, and market development.

Switching from a wood-fuelled cooking fire to a biogas flame saves trees and time, reduces greenhouse gas emissions and prevents health problems. Community-based cooperatives in the Terai plains of Nepal are using carbon credits to fund micro-loans for families to install the technology.

Floods are one of the most common hazards in the world, affecting people’s lives and livelihoods. Flood hazard mapping and flood shelters suitability analysis are vital elements in appropriate land use planning for flood-prone areas. This paper describes application of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are therefore important tools for planners and decision makers. The purpose of this article is to describe a simple and efficient methodology to accurately delineate flood inundated areas, flood-hazard areas, and suitable areas for flood shelter to minimize flood impacts. Possible extent of flooding and suitable location flood shelter sites were modeled and mapped for Sindh Province in Pakistan, using the software ArcGIS model builder. The output was validated using inundation maps based on flood events that took place in 2010 in Pakistan. These were mapped using object-based image analysis (OBIA) implemented in eCognition software. The catastrophic flood of 2010 inundated a total area of 7579 km2, while the modeled result indicated the hazard area to be 6216 km2 out of 46138 km2. Discrepancies in modeled and mapped results are insignificant and acceptable considering the manual flood management interventions which are beyond the capability of models to represent. Thus, this method is robust enough to develop flood hazard zoning maps and map shelter sites for flood management.

The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains and fertile lands highlight the requirement of proper planning for groundwater management and governance to reduce poverty and assure food security. The aim of this report is to assist planners/policymakers in the planning and management of groundwater resources in the EGB. This report mainly discusses about hydrogeology, groundwater potential and challenges, and groundwater quality issues in the EGB. Moreover, it is an attempt to form a base for future work related to groundwater development, management and modeling in this basin.

This article highlights the continued significance of pre-capitalist formations in shaping the trajectory of economic transition in peripheral regions, even in an era of neo-liberal globalisation. There is a tendency for Marxist scholars to assume the inevitable “dominance” of capitalism over older modes of production. Using a case study from Nepalapos;s far eastern Tarai, this paper seeks to understand the reproduction of feudal social relations in a region which is both accessible and integrated into regional and global markets. The paper traces the early subordination of indigenous groups to feudalism from the eighteenth century onwards, and the political and ideological processes through which these social relations were reinforced. Through examining the historical role of feudal-colonial alliances, however, the paper notes that pre-capitalist reproduction in Nepal is a dynamic process, actively negotiated and reinforced by the external imperatives of capitalist expansion itself as well as through the entrenched political power of landed classes. Today feudal and capitalist formations co-exist and articulate, with surplus divided between landlords and non-farm employers. Understanding the complex dynamics of feudal or “semi-feudal” reproduction in an era of globalisation is crucial if one is to identify avenues for collective mobilisation against inequitable pre-capitalist and capitalist class relations.

Project Preparatory Technical Assistance 7883-NEP

Despite decades of investment and institutional refinement, externally funded irrigation programs still exhibit low success rates and more particularly in countries facing institutional and political challenges. This paper aims at bringing fresh insights on the reasons for such shortcomings with the particular case study of a donor-sponsored program recently implemented in the Mid and Far Western Regions of Nepal.; Findings indicate that the political situation and institutional system in Nepal have substantially affected the outcomes of the agricultural water management (AWM) interventions conducted by the program. Yet, beyond the influence of these contextual factors, two other (less acknowledged) mechanisms have contributed to create a gap between project objectives and outcomes: a) concepts commonly found in project documents and development discourses such as participation or empowerment are kept vague and ambiguous and lack an explicit recognition of power distribution; and b) the organizational system of many funding agencies tends to create incentives for project staff to show outcomes rather than to make impacts.; These findings suggest that refining current models of AWM interventions is not sufficient to improve their achievements. A more radical shift is needed. A few avenues for change include to: 1) pay a greater attention to the meaning and operationalisation of common development concepts (e.g., rights based approach, empowerment or participation); 2) consider the way interventions affect power distribution among stakeholders, including communities; and 3) modify the organizational system of the funding agency to increase its downward accountability to targeted beneficiaries. To sum-up, we need to rethink development as a means of empowering governments and citizens rather than as a way to provide assistance.

The Melamchi Water Supply Project (MWSP) is designed to minimize the shortage of drinking water in the Kathmandu valley. Although the project was supposed to be completed by 2008, due to various problems, it is still diffi cult to forecast the exact date of completion. This paper quantifi es the downstream effects of diverting water from the Melamchi (Stage-I),Yangri (Stage-II) and Larke (Stage-III) rivers under current as well as future climate scenarios. The Soil Water Assessment Tool (SWAT) was used in the analysis. Result shows that in the Stage-I water transfer plan, average infl ow reduction in the immediate downstream sub-basin in the dry and wet seasons are 36% and 7% respectively, where as in Stage-II the infl ow reductions are 38% for the dry season and 8% for the wet season. In Stage-III, infl ow reductions are 38% in the dry season and 7% in the wet season.; The impact of the water transfer schemes on various changes in water management within the Melamchi River irrigation command area was also tested. BUDGET (soil, water and salt balance) model was used to quantify crop water requirement of Melamchi River command area when the irrigated area is increased and the cropping pattern is changed. Simulation results of crop water requirement in intensive water use conditions show that present Melamchi River command area can be increased by 2.2 times under current climate projection, whereas the area can be increased 1.4 times in 2030s and by 2.0 times in 2050s.

Assessment of surface and groundwater resources and water availability for different sectors is a great challenge in Nepal mainly due to data limitations. In this study, the Soil Water Assessment Tool (SWAT) was used to simulate the hydrology and to calculate sub-basin wise water balances in the Koshi Basin, Nepal. The impacts of Climate Change (CC) projections from four GCMs (CNRM-CM3, CSIRO-Mk3.0,ECHam5 and MIROC 3.2) on the hydrology of the basin were also calculated. This paper summarizes some of the key results. The full report of the study is in preparation.; The basin can be divided into the trans-mountain, central mountain, eastern mountain, eastern hill and central hill regions. Results show that current precipitation is highest in the central mountain and eastern mountain regions during both the dry and wet seasons. Water balance results showed that Actual ET as well as Runoff is also highest in the central and eastern mountain regions followed by the mid-hills. Results from climate change projections showed that average temperature will increase in the 2030’s by 0.7-0.9 Celsius. Results for 2030s projections also show that during the dry season, precipitation increases in the trans-mountain but decreases in the other regions for both A2 and B1 scenarios. During the wet season, the MarkSim projections show a decrease in precipitation in all the regions.; Net water yields also increased for the trans-mountain zone during the dry season but show varying results during the monsoon. Assessment of projected future fl ow time series showed that there will be an increase in the number of extreme events; i.e., both low fl ows and large fl oods. There is however; a high degree of uncertainty in the projected climate data as the relative standard deviation was quite high.

Eco-toilets (human urine and faecal matter collected separately) are one of the best ways to solve sanitation problem, and this practice also improves the environment and increases the food production. This study focuses on experimental demonstration of use of urine, wood ash and poultry droppings (PD) as a fertilizer in central Nepal and in Accra, Ghana. In Nepal; Fertilizer value of urine+ash was compared with animal manure and no-fertilization in the cultivation of radish, potato, broadleaf mustard, cauliflower and cabbage. The urine + ash or manure fertilized plots received 54 kgN/ha for radish, 51 kgN/ha for potato, 81 kgN/ha for broadleaf mustard and 77 kgN/ha for cabbage and cauliflower. Similarly in Ghana; urine was compared no fertilization and urine + PD (poultry dropping) was compared with NPK (mineral fertilizer)+PD as a dose of 121 kgN/ha. In Nepal; the urine+ash fertilizer produced significantly (Plt;0.05) higher broadleaf mustard biomass than obtained from animal manure and without fertilization. It was demonstrated that urine+ash can produce higher yields than manure fertilizer; the differences being gt;24 t/ha radish tuber, gt;95 kg/ha potato tuber, gt;19 t/ha cauliflower total biomass and gt;15 t/ha cabbage total biomass. In Ghana; urine produced 1.2 ton/ha more cabbage head biomass compared to no fertilization and urine+PD produced 0.82 t/ha more cabbage head biomass compared to NPK+PD. Furthermore, in Nepal; N-fertilizer value of 4 litres urine is equal to the 1 kg of dry manure and in Ghana N-fertilizer value of 2 litres of urine is equal to 1 kg of poultry droppings. In conclusion, human urine can be used as fertilizer alone or combined with wood ash and poultry droppings and this can produce similar or even more vegetable biomass than can be achieved with no fertilization, manure fertilization or NPK+PD.

Climate change is one of the drivers of change in the Ganges River Basin, together with population growth, economic development and water management practices. These changing circumstances have a significant impact on key social and economic sectors of the basin, largely through changes in water quantity, quality and timing of availability. This paper evaluates the impact of water on changing circumstances in three sectors of the Ganges Basin – agriculture, ecosystems and energy. Given the inherent interconnectedness of these core sectors and the cross-cutting impact of changing circumstances on water resources, we argue that adaptation should not be viewed as a separate initiative, but rather as a goal and perspective incorporated into every level of planning and decision making. Adaptation to changing circumstances will need to be closely linked to water resource management and will require significant collaboration across the sectors.

The topography of Ganges basin (GB) is much contrasted with upstream steep mountainous region of the Himalayas and downstream large fertile plains in eastern India and Bangladesh. The Himalays are partly covered by snow and glaciers that seasonally release water to the river network of GB and provide cushion against the annual fluctuations. The contribution from the glaciers to the streamflows is supposed to be significant although spatilly distributed quantification is unavailable. Moreover, there is uncertainity on the impact of climate change on glaciers and the resultant streamflows. We set up an application of the Water Evaluation and Planning (WEAP)model which contained an experimental glaciers module that accounts for snow and glaciers processes in the GB. The model also examined the possible impacts of an increase in temperature of +1, +2 or +3 degree Celsius over 20 years of the simulation period (1982-2002). The average annual stream flows in the GB that comes from melting of snow and ice in glaciated areas is significant (60-75%) in the Upper Ganga and in the Nepalese sub-basins. The share, however, reduces significantly further downstream, falling to about 19% at Farakka as flows from glaciated areas are diluted by streamflows generated by rainfall/ runoff processes. Climate change-induced rise in temperature logically increases the quantity of snow and ice that melts in glaciated areas , causing an augmentation of streamflows. However, this impact decreases from upstream ( +8% to +26% at Tehri Dam in Uttaranchal in India) to downstream (+1% to +4% at Farakka in West Bengal). Such increases in streamflows may create flood events more frequently or of higher magnitude in the Upper Ganga or in the mountainous sub-basins. In terms of water use, most of the extra water from glaciated areas do not flow when water is most required i.e. during the lean flow winter and early summer season. Potential strategy to exploit this additional water may include construction of new dams/ reservoir storages that could be used locally or within the transboundary agreements or to capture this extra water just at the end of the dry season (April-June) when flows from glaciated areas become noticeable. Enhancing the development of groundwater in the basin (from the present low level of ~ 30 per cent) through managed aquifer recharge and other suitable options shall be an equally viable option. The riparian states within India and India-Nepal- Bangladesh may harness this opportunity to alleviate physical water scarcity and transboundary water conflicts.

The environmental services related with agricultural water are increasingly acknowledged as a critical factor for farming development in South Asia. However, little attention is given to the demand side linked with the preservation of these services. To this aim, we conduct a stated preference approach for the elicitation of farmers’ preferences towards the economic value rendered to environmental services related with agricultural water. The research is based on an extensive survey in selected clusters of India, Pakistan and Nepal. The case studies are situated along Indo-Gangetic basin due to more evidential linkages between environmental services and irrigation. The findings depict a highly agreeable stance of Indian and Nepalese farmers for the contribution to environmental services while the majority of Pakistani are opposed to such a contribution. However, they almost all agree on the type of the assessment approach while the agreeable Pakistanis offer the highest contributions. The association of the economic assessment with key wealth indicators and socio-demographic elements depicts the high significance of household size.

Groundwater is of paramount importance as resource input to smallholder irrigated agriculture in many parts of Asia today, both for securing subsistence farming as well as part of economic livelihood strategies. It is estimated that 1 billion farmers across India, China, Pakistan, Bangladesh and Nepal are reliant on groundwater for their farming. However, despite and in some places because of effective and widespread technologies for accessing and utilizing groundwater, the farmers often encounter constraints in their further development and benefit optimizing of this resource. As part of devising policies and programs that contribute towards sustainable farming systems, integrated land use planning, effective use of water resources, increased food production, and adaptation to global changes in climate, demography, and economic conditions, it is key to understand the realities of farmer interaction with and impediments for utilizing groundwater in these parts of the world. Data and results are presented from action research carried out in the alluvial sedimentary basins of the Indo-Gangetic and Yellow River systems (Fig. 1) as part of a major training and research capacity building effort for groundwater professionals from these five Asian countries. A subsidiary objective to the capacity building aim was to gain insight into and collect key figures and comparative descriptions of the physical, the agricultural, and the household economic conditions for the poor farmers to engage in groundwater irrigation. Major constraints for groundwater use relate to exhaustion of the resource (Yellow River Basin, the North China Plains and western India) and to lack of reliable or affordable energy sources for the pumping of groundwater (eastern India and Bangladesh). Agricultural production levels are relatively low in a global context, particularly in the poorest areas, reflecting other constraints, such as lack of other production inputs and supporting market and service infrastructure. Nowhere is groundwater managed actively and directly, though few examples of local and social schemes for management were encountered. Adaptation or coping strategies of the farmers varied from drilling deeper wells and implementing more efficient pumps in over-exploited areas to substituting expensive diesel fuels with the subsidized cooking oil kerosene in areas with plenty of groundwater but poor energy sources (Table 1). In most places, farmers respond by diversifying crops and livelihood income sources. Migration is also practiced but not always to the effect of relieving further stress on groundwater. General recommendations are provided for addressing the groundwater-related constraints in the diverse landscape of groundwater based economies.

Predicting river flows in basins where limited data is available is a challenge facing many hydrologists especially in developing countries. In this study, the Pitman monthly model was applied to generate flows for the Lhasa Basin in China (Tibet). As flow data was unavailable for the Lhasa basin, the model was first calibrated for the upper Koshi Basin in Nepal and China. The Pitman model successfully predicted flows for the upper Koshi basin (R2=0.88). Therefore, the estimated model parameters from the Koshi basin as well as climate data from the Lhasa basin were used to generate flows for the Lhasa basin outlet. The main modeling assumption is that the basin characteristics of the upper Koshi are similar to that of the Lhasa basin. Under present circumstances, where measured data is unavailable, the model estimated monthly flows for the Lhasa basin can be used in further studies in basin water accounting and management.

International Water Management Institute, the then International Irrigation Management Institute (IWMI) began its activities in Nepal since 1986 with a Memorandum of Understanding with His Majesty’s Government of Nepal, now the Government of Nepal. The primary objectives were to strengthen the research capability of Water and Energy Commission Secretariat, promote collaborative research in Farmer Managed Irrigation Systems (FMIS), Irrigation Management Transfer (IMT) and Agency Managed Irrigation Systems (AMIS). Pioneering researches in FMIS and AMIS were carried out in Nepal by IWMI and it laid impact on participatory irrigation management through understanding the role of water users association for effective management of irrigation system. The researches in Nepal was also important for its contribution to the water sector management in the developing country through the promotion of science based studies and action research. The main areas of contribution of IWMI research were in policy formulation, methodology development and Institutional Strengthening and Capacity Building for irrigation research. Therefore, this paper will try to look into the FMIS, AMIS and other researches that IWMI has undertaken, their importance for water management in Nepal and the lessons learnt is expected to be of interest to policy makers, planners, researchers and the scientific community.

Traditionally, the users’ organisations at local level are playing an important role for the management of natural resources by organizing the users. The Government of Nepal through its Water Resources Strategy 2002 and National Water Plan 2005 has emphasized a holistic approach in place of sectoral one for natural resources management at sub/basin level based on the principle of Integrated Water Resources Management (IWRM). It envisages the creation of committee at the sub/basin level, which is lacking at present. But both vertical and horizontal linkage between institutions and among the various water users is sectoral. Therefore, an action research was carried out in Nepal and India to examine the possibility of up-scaling the role of existing natural resource users’ group and other stakeholders - local elected institutions and I/NGOs in order to facilitate the evolvement of institution at sub/basin level. The information was collected through checklist in focused group discussions, consultation workshop at the local and district level with Water users group, Forest Users Group and other stakeholders. The dynamics of resource management along with stakeholders’ role and processes/methods followed in ‘Platform’ formation, which is expected to evolve as sub/basin level institutions for IWRM in Nepal and its future is dealt in this paper.

The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.

This paper assesses the agricultural water consumption and productivity of the predominant crop paddy rice and wheat for the Indo-Gangetic river basin (IGB) in South Asia. A new approach was adopted in the study to integrate census, remote sensing and weather data to assess crop water productivity (WP) across large scale. The average paddy field ET for rice for major growing period of June 10 to October 15 is 416 mm, which is 70% of rice potential evapotranspiration (ETp, equals to ET0*Kc). Average rice water productivity is 0.74 kg/m3. The average evapotranspiration (ETa) and WP of wheat is 299 mm and 0.94 kg/m3 respectively. Significant variations were observed for the ETa, yield and WP of rice and wheat. The scope for improvement of water productivity could be assessed by comparing “hot” and “bright” spots in consultation with factors such as rainfall and topography. It is found while improving yield in long term will finally lead to improved WP, reducing non-beneficial ET from low yield areas is a effective approach to improve WP in short term. Integrated land, crop and water management is the key to sustainable development of the region.

The significance of environmental services related with irrigation is increasingly acknowledged as a critical factor for agricultural productivity in South Asia. However, little is known about farmers’ willingness to contribute for the preservation of these services. To this aim, we conduct a stated preference approach for the elicitation of farmers preferences towards the economic value attributed to environmental services related with agricultural water use. The research is based on results from an extensive survey in selected clusters of India, Pakistan and Nepal. The case studies are situated along Indo-Gangetic basins due to the presence of more evident environmental problem linked with irrigation. The findings present a highly agreeable stance of Indian and Nepalese farmers towards the contribution to the environmental services while the majority of Pakistani is opposed to such a contribution. However, they all agree on the type of the assessment approach. The association of the economic assessment with key wealth indicators and socio-demographic elements depicts the high significance of household size.

The impact of climate change (CC) on water resources is likely to affect agricultural systems and food security. This is especially true for Nepal, a least developed country, where a high percentage of the population is dependent on agriculture for its livelihoods. It is thus crucial for Nepal’s leaders and resource managers to draft and begin implementing national adaptation plans. This working paper aims to create a more comprehensive understanding of how the impacts of CC will be realized at different scales in Nepal, from household livelihoods to national food security, and the many institutions governing the ultimate adaptation process.

Crop consumptive water use and productivity are key elements to understand basin watermanagement performance. This article presents a simplified approach tomap rice (Oryza sativa L.) water consumption, yield, and water productivity (WP) in the Indo-Gangetic Basin (IGB) by combining remotely sensed imagery, national census and meteorological data. The statistical rice cropped area and production data were synthesized to calculate district-level land productivity, which is then further extrapolated to pixel-level values using MODIS NDVI product based on a crop dominance map. The water consumption by actual evapotranspiration is estimated with Simplified Surface Energy Balance (SSEB) model taking meteorological data and MODIS land surface temperature products as inputs. WP maps are then generated by dividing the rice productivity map with the seasonal actual evapotranspiration (ET) map. The average rice yields for Pakistan, India, Nepal and Bangladesh in the basin are 2.60, 2.53, 3.54 and 2.75 tons/ha, respectively. The average rice ET is 416 mm, accounting for only 68.2% of potential ET. The average WP of rice is 0.74 kg/m3. The WP generally varies with the trends of yield variation. A comparative analysis of ET, yield, rainfall and WP maps indicates greater scope for improvement of the downstream areas of the Ganges basin. The method proposed is simple, with satisfactory accuracy, and can be easily applied elsewhere.

The basins of the Indus and Ganges rivers cover 2.20 million km2 and are inhabited by more than a billion people. The region is under extreme pressures of population and poverty, unregulated utilization of the resources and low levels of productivity. The needs are: (1) development policies that are regionally differentiated to ensure resource sustainability and high productivity; (2) immediate development and implementation of policies for sound groundwater management and energy use; (3) improvement of the fragile food security and to broaden its base; and (4) policy changes to address land fragmentation and improved infrastructure. Meeting these needs will help to improve productivity, reduce rural poverty and improve overall human development.

The International Water Management Institute (IWMI) has been working in Nepal since 1986 with the objective of undertaking research in water management and to strengthen the research capabilities of concerned government agencies. The research helped to develop appropriate mechanisms for providing support to Farmer-Managed Irrigation Systems (FMIS) and the initiation of participatory irrigation management (PIM). The river basin studies helped policy formulation for integrated planning and management of water resources besides the methodological contribution through the development of appropriate tools for water management studies. It also contributed to enhancing the capabilities of agency officials and local researchers through their involvement in research activities.

In low- and middle-income countries, people need water for drinking, personal hygiene and other domestic use. But they also use it for livestock, horticulture, irrigation, fisheries, brickmaking, and other small-scale enterprises. Multiple-use water services (MUS) are best suited to meeting people’s needs. However, most water services are designed only for domestic water or only for agriculture, and fail to reflect its real-life use. The action research project ‘Models for implementing multiple-use water supply systems for enhanced land and water productivity, rural livelihoods and gender equity’ developed case studies in eight countries (Bolivia, Colombia, Ethiopia, India, Nepal, South Africa, Thailand and Zimbabwe) involving 150 institutions. The project analysed two models: homestead-scale and community-scale MUS and developed a ‘multiple-use water ladderapos; to show how better livelihoods flow from increased access to water. This book shows how livelihoods act as the main driver for water services and how access to water is determined by sustainable water resources, appropriate technologies and equitable ways of managing communal systems. Climbing the water ladder requires a small fraction of total water resources, yet has the potential to help people climb out of poverty. Local government can be the pivot to make this happen. But, it needs support to implement its mandate to meet multiple-use demand and to become more accountable to people in communities.

‘‘Getting prices right” is the silver bullet widely advocated to developing countries in fighting waste, misallocation and scarcity of water. In the vast, poverty-stricken Indo-Gangetic basin, however, high surrogate water price is driving out small-holder irrigation. With rising diesel prices, most small-holders who use borewells for irrigation find effective water use cost soaring, obliging them to economize on water use even by quitting irrigated farming. Electrified borewell owners, far fewer, face low marginal cost but have to contend with stringent electricity rationing. Public irrigation systems grossly under-price irrigation, but these are getting marginalized despite massive government and donor investments.

Groundwater has played an increasing role in irrigated farming, livelihood support, poverty alleviation, and national food security in India, China, Pakistan, Bangladesh, and Nepal since the advent of the green revolution in the 1960s. This paper presents a synthesis of the results of a cross-regional research effort, based on surveys in more than 60 villages, to map the contemporary realities and constraints of groundwater use and adaptation in irrigated agriculture within smallholder farmer communities across the alluvial plains of the major Indus, Ganges and Yellow river basins in Asia. The results show a general over-exploitation of groundwater resources in Pakistan, western India, and China and relative under-utilization in eastern India and Bangladesh. But more interestingly, and despite its great significance, practically nowhere is groundwater managed in an integrated manner. As a result, its use is sub-optimal where smallholders today employ a range of adaptation and coping strategies to uphold groundwater benefits. The research findings point to various axes along which to identify solutions and focus equitable and sustainable policies and management interventions.

Since the early 2000s, a new participatory approach to water services delivery is emerging: multiple-use water services (MUS). By overcoming sectoral boundaries within the water sector, new opportunities are opened up that better align with people’s practice of using water from multiple sources for multiple uses. Two opportunities are discussed in this paper on the basis of past research by the CGIAR Challenge Program on Water and Food, among others. One new opportunity is homestead-scale MUS. Providing double or triple the quantities of the design norms in the domestic subsector in poor rural and periurban areas allows water users to take up significant productive activities besides meeting domestic needs. Cost–benefit ratios are favourable. Homestead-scale MUS is the most effective way of using water to contribute to all Millennium Development Goals. A related second new opportunity is community-scale MUS. This participatory approach to water services considers communities’ holistic water-and landscapes and supports incremental improvements in infrastructure according to people’s own priorities and needs, which are often in favour of homestead-scale MUS. New synergies in infrastructure intakes, storage and conveyance are tapped.

Irrigation using groundwater has expanded rapidly in South Asia since the inception of the Green Revolution in the 1970s. Groundwater currently represents the largest source of irrigation in the Indus-Ganges Basin (IGB), which feeds over one billion people and provides direct livelihoods for hundreds of millions of farmers. Although abundant in absolute terms, groundwater is overexploited in the western IGB plains and is underutilized in the east. The spatial and temporal patterns of groundwater development are the result of multiple demand factors: (a) farmer investment, (b) subsidies and markets, and (c) population density; as well as supply factors: (d) sources of groundwater recharge, and (e) energy supply and pricing. This paper examines trends in electricity supply and groundwater development in the Indian portion of the IGB over the 1980 – 1999 period, with contextual reference to groundwater irrigation in Pakistan, Nepal, and Bangladesh. Principal findings include early-1980s’ growth in numbers of electric pumps across the Indian IGB followed by 1990s’ stagnation in the eastern part of the basin; this trend is linked to electricity supply and pricing policies, which have varied markedly from state to state. The eastern IGB presents an energy-groundwater paradox: a region rich in energy sources but with inadequate electricity supply that has led to increased reliance on diesel power, which in turn is limiting development of groundwater – one of this region’s most abundant and agriculturally productive resources.

This paper gives an overview of water resources, its availability and use, problems and constraints, the present and future challenges and the ensuing opportunities in water resource sector of one of the most populated river basins of the world; the Indus-Gangetic basin. Large-scale development of water resources in the Indus basin has led to the resource base being depleted, both in terms of quantity as well as quality. Well-developed surface irrigation systems in the Indus basin tap most of the surface water available in the basin, leaving only 10% of the net runoff to the sea, whereas from Ganges basin, the net runoff flowing to the sea is about 40%. Groundwater, which is expected to serve as buffer source to compensate for the reduced surface water availability, is also getting depleted. Energy and agricultural sector policies followed also favour large scale exploitation of groundwater resources in the basin, which has led to water table decline and a reduction in environmental flows. In the Gangetic part of the basin, it is the economic water scarcity which is more prominent. Equally important is the deterioration of water quality of Ganges river, especially when it flows along the plains accumulating municipal, industrial and domestic waste from the rapidly growing cities situated along its banks. Compounded with these issues is the role played by climate change. Since both Indus and Ganges rivers are heavily dependent on snow and glacier melts, the streamflow in these rivers is highly sensitive to climate change. Recent years have witnessed some responses to the water scarcity problem in IG basin the form of popularization of resource conservation practices, growing high yielding short duration varieties of paddy, micro and precision irrigation, regulations to control groundwater use and management. The article presses the need for water resources in the basin to be managed in a conjunctive manner, considering rain water, surface water, soil water and groundwater in continuum. Considering the inter-linkage between groundwater extraction, energy and food policies, groundwater management strategies should have a focus on energy pricing, food pricing and procurement policies also. Nevertheless, devising long-term strategies on water resource management in the basin need not overlook the likely impacts that the changing climate is going to have on water resources.

Technical interventions have not always led to expected outcomes when attempting to achieve a balanced growth between natural resource development and food production, particularly in the context of Third World countries. In Royal Chitwan National Park (RCNP) buffer zone, Nepal, farmers’ perceptions were used to evaluate how irrigation resource development and the method of water sharing have increased household food security and reduced pressure on natural resources of the park. The findings indicate that with some variations between communities, increased water availability and reliability through irrigation development have improved crop diversity, cropping intensity, food sufficiency, and economic return to farmers. Community attributes such as leadership and dynamics were, among others, the decisive factors that determined the degree of success of the government development intervention programme in the buffer zone. Small landholders and low-income groups in dry areas perceived that they received greater benefits from micro-groundwater pumping schemes. However, many rural poor inhabitants in the area still lack access to these resource opportunities. We observed that Park and People, a government programme, successfully improved public relations and helped create awareness in this buffer zone. However, grievances persist among other water user groups in the upstream part of the Rapt River where a water sharing mechanism needs to be defined between water user associations for crop production and maintenance of biodiversity of the national park.

Understanding of crop water productivity (WP) over large scale, e.g., river basin, has significant impli-cations for sustainable basin development planning. This paper presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat WP in In-do-Gangetic River Basin, South Asia. A crop dominance map is synthesized from ground truth data and three existing LULC maps. National statistics on crop area and production information are collected and the yield is interpolated to pixel level using moderate resolution imaging spectroradiometer (MODIS) normalized difference vegetation index (NDVI). Crop evapotranspiration is mapped using simplified surface energy balance (SSEB) model with MODIS land surface temperature products and meteorological data collected from 56 weather stations. The average ET by rice and wheat is 368 mm and 210 mm respectively, accounting for only 69% and 65% of potential ET, and 67% and 338% of rain-fall of the crop growth period measured from Tropical Rainfall Measurement Mission (TRMM). Average WP for rice and wheat is 0.84 and 1.36 kg/m3 respectively. WP variability generally follows the same trend as shown by crop yield disregarding climate and topography changes. Sum of rice-wheat water productivity, however, exhibits different variability leading to better understanding of irrigation water management as wheat heavily relies on irrigation. Causes for variations and scope for improvement are also analyzed.

To mitigate a drinking water crisis in Kathmandu valley, the Government of Nepal initiated the Melamchi Water Supply Project in 1997, which will divert water from the Melamchi River to Kathmandu city’s water supply network. In the first phase, the Project will divert 170,000 cubic meters of water per day (at the rate of 1.97M3/sec), which will be tripled using the same infrastructure as city water demand increases in the future. The large scale transfer of water would have far reaching implications in both water supplying and receiving basins. This paper analyzes some of the major changes related to local water management and socioeconomics brought about by the Project and in particular the changes in the local water management institutions in the Melamchi basin. Our study shows that traditional informal water management institutions were effective in regulating present water use practices in the water supplying basin, but the situation will vastly change because of the scale of water transfer, and power inequity between the organized public sector on one side and dispersed and unorganized marginal water users on the other. The small scale of water usage and multiple informal arrangements at the local level have made it difficult for the local users and institutions to collectively bargain and negotiate with the central water transfer authority for a fair share of project benefits and compensation for the losses imposed on them. The process and scale of project compensation for economic losses and equity over resource use are at the heart of the concerns and debates about the Melamchi water transfer decision. The Project has planned for a one- time compensation package of about US$18 million for development infrastructure related investments and is planning to share about one percent of revenue generated from water use in the city with the supplying basin. The main issues here are what forms of water sharing governance, compensation packages, and water rights structures would emerge in relation to the project implementation and whether they are socially acceptable ensuring equitable distribution of the project benefits to all basin communities. In addition, these issues of the Melamchi project discussed in this paper are equally pertinent to other places where rural to urban water transfer projects are under discussion.

The project CP 23, “Resource Management for Sustainable Livelihood” was a three year project, starting from April 2005 and ending in September 2008 with a no cost extension of six months from April 2008. It aimed at contributing to enhanced livelihood opportunities and reduced vulnerability for poor rural people in upper catchments, through understanding of legal, policy and institutional provisions for resource management in Nepal and India, resource assessment and livelihood analysis in the studied area, exploring expanded mandates for the existing resource users’ groups and possibility for scaling up their activities. To fulfill the objectives, researchers advanced a range of activities such as household survey, PRA exercises, formal and informal meetings, GIS, establishment of rain gauge stations, data interpretation and analysis, etc.

Groundwater irrigation has emerged as a major socio-technical reality and has added substantive economic gains in the Indo-Gangetic Basin countries. In the Indo-Gangetic Basin the hydrology and socio-ecology and the associated agriculture and human livelihoods undergo significant shifts as one traverses from the semiarid and water-scarce Indus Basin in the northwest to the sub-humid and water-sufficient eastern Gangetic Basin. However, basin-wide analysis shows that stage of development and utilization of the groundwater resource has limited relationship to the abundance of resource availability. Studies made at five sites in the basin under the CPWF Groundwater Governance in Asia (GGA) Project revealed that groundwater use produced higher benefits as compared to canal irrigation and conjunctive water use. Small and marginal farmers with scattered land holdings do not, however, have sufficient resources to install their own pump sets, and must depend upon their neighbors for purchase of groundwater. Furthermore, a mismatch between the basin hydrological conditions and the energy policies are leading to over-exploitation of the resource in the Indus Basin and constraining the optimal use of the resource in the eastern Gangetic Basin. We present policy options for improving the productivity, livelihoods, and resource sustainability for the small and marginal farmers of the basin.

The following paper is concerned with water sharing of the Ganges River between India and Bangladesh, with possible augmentation through water transfers from Nepal. We analyzed the case when water from Nepal can be transferred to Bangladesh through the upstream country, India, as the local geography only permits such water transfer. A game theoretic model is formulated to determine the optimal share of water diverted to Bangladesh by India, and the optimal amount of water transfer from Nepal. India may gain positive externalities from such water transfer. The positive externalities generated fromwater transfer fromNepalmay influence thewater share of both India and Bangladesh. In the absence of altruism, India would allow less water flow to Bangladesh than in the case when there is no provision to buy water from Nepal. We also explored whether positive externalities could induce India to buy water jointly with Bangladesh, and such a case will only occur if the countries possess altruistic concerns and share water according to an agreement.

Although the protection of the aquatic environment is high on the world water resources agenda, most developing countries still lack the technical and institutional capacity to establish environmental water allocation practices and policies. The existing methods of assessment of environmental water allocations are either complex and resource-intensive or not tailor-made for the specific conditions of a particular country or region. To promote emerging concepts of environmental flow assessment and management, it is important to change the dominant perception that environmental demand is the least important and create awareness among responsible authorities about existing methodologies and processes that should be followed. This report presents some of these approaches and illustrates their applicability in the specific context of the East Rapti River basin, which features one of the main tourist attractions of Nepal, the Chitwan National Park.

In the highly populated South Asian region, where pump irrigation has gained predominance over gravity-flow irrigation in recent decades, the fortunes of groundwater and energy economies are closely tied. Little can be done in the groundwater economy that will not affect the energy economy, and the struggle to make the energy economy viable is frustrated by the often violent opposition from the farming community to the rationalization of energy prices. As a result, the regionapos;s groundwater economy has boomed at the expense of the development of the energy economy. This report suggests that this does not have to be so; and the first step to evolving approaches to sustaining a prosperous groundwater economy with a viable power sector is for the decision makers in the two sectors to talk to each other, and jointly explore better options for energy-groundwater co-management which, the authors suggest, have so far been overlooked.

The case studies reported here highlight important concepts and information on the linkages between water and poverty that may not be available elsewhere. The overall objective of the studies is to draw generic lessons and identify interventions that can help policy makers, planners and other stakeholders to develop actions that are effective in water resources management for the poor. All case studies focus on poor in South Asia, but all with differing geographic contexts or thematic focci. The first two papers are based on field surveys supplemented by literature reviews. The first focusses on the impact of water on poverty in a mountainous region in Nepal, while the second focusses on the impact of drought on water availability, and hence poverty, in a district in Pakistanapos;s Baluchistan province. The final two papers both took Sri Lanka as their area of study. The first Sri Lanka paper explores the linkages between water, health and poverty and presents a conceptual framework which was used to analyze the results of previous studies. Sri Lankaapos;s dry zone is the geographic focus of the second paper, which focusses primarily on the linkages between irrigation and poverty.

Research highlight based on a paper titled Groundwater socio-ecology of South Asia: An overview of issues and evidence

This report is based on a research project financed by the Asian Development Bank (ADB) to conduct a regional study for the development of effective water management institutions (ADBRETA no 5812). Research activities were conducted in five river basins in Indonesia, the Philippines, Nepal, China and Sri Lanka for a period of three years commencing from 1999. The river basin studied in Sri Lanka was the Deduru Oya river basin in the North Western Province of the country. This report contains the findings of the Deduru Oya basin study. The overall objective of the case study conducted in Sri Lanka was to help the government of Sri Lanka to improve the institutions managing scarce water resources within the frame work of integrated water resources management. This case study included a comprehensive assessment of the existing physical, socio-economic and institutional environment in the river basin and also the long term changes that are likely to take place.

Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies gender issues beyond a strict mandate of irrigation water provision. The Indicator was applied and tested in nine case studies in Africa and Asia. The research report presents the underlying concepts, methodological guidelines and selected applications of the GPII.

Examines the gendered organization of irrigated farming and identifies processes of inclusion and exclusion of women irrigators and women leaders in water users committees. The research evaluates the success of efforts by the newly formed Water Users Association to include women. Recommendations based on the findings are made to address the problems faced by the women irrigators and leaders in the West Gandak scheme.
