The United Nations Sustainable Development Goals (SDGs) describe a course of action to address poverty, protect the planet and ensure prosperity for all (https://sdgs.un.org/goals). More specifically, SDG 6 clarifies how water quality, quantity and access are crucial to human well-being, and yet human activities are compromising water resources through over-exploitation, pollution, as well as contributing to the spread of disease. Globally aquatic ecosystems are highly threatened and concerted efforts by governments and civil society to ‘turn the situation around’ are simply not working. Human-created problems require human-centred solutions and these require different ways of thinking and acting to those behaviour patterns that are contributing to the challenges. In this paper, we first consider causal approaches to attitude change and behaviour modification that are simply not working as intended. We then explore enabling responses such as citizen science and co-engaged action learning as more tenable alternatives. SDG 6 has a focus on clean water and sanitation for all. The SDGs further clarify how the extent to which this goal can be realized depends, to a large extent, on stakeholder engagements and education. Through stakeholder engagements and educational processes, people can contribute towards SDG 6 and the specific indicator and target in SDG 6.b Stakeholder participation. Following a three-year research process, that investigated a wide range of participatory tools, this paper explores how the Stream Assessment Scoring System (miniSASS; www.minisass.org) can enable members of the public to engage in water quality monitoring at a local level. The paper continues to demonstrate how miniSASS can contribute to the monitoring of progress towards Sustainable Development Goal Target 6.3, by providing a mechanism for data collection indicator 6.3.2. miniSASS is proving popular in southern Africa as a methodology for engaging stakeholder participation in water quality monitoring and management. The technique costs very little to implement and can be applied by children and scientists alike. As a biomonitoring approach, it is based on families of macroinvertebrates that are present in most perennial rivers of the world. The paper concludes by describing how useful the miniSASS technique can be for addressing data gaps for SDG 6.3.2 reporting, and that it can be applied in most regions of the world.

The history of Karamoja, a subregion in the far northeast of Uganda, is complex and scarred by conflict. For centuries, this subregion has been a remote area of agropastoralism situated on the sociological and ecological border between the Nile and Turkana basins. At the far eastern tip of the Nile Basin, a sweeping escarpment from Karamoja runs down into the Lake Turkana Basin with major temperature and rainfall gradients that result in significant patterns of transhumance, as the Turkana people to the east seek access to the more plentiful water and grazing resources in Karamoja to the west. In this paper, we call this complex of relations and resources the ‘Karamoja-Turkana Complex’ (KTC) and examine the political-economy relationships therein.
We look at policy on water resources management and development, including choices made on siting and developing water sources, the kinds of narratives employed by the government, and the underlying tensions and conflicts between major social groups sharing these scarce resources. We base our analysis of the situation on a wider assessment of the water management challenges combined with a detailed examination of two large dams Arachek and Longoromit recently constructed in the Karamoja subregion.
Findings from the study highlighted that (i) interlinked systems within the KTC can generate new disputes and pressures on resources; (ii) water management within Karamoja and Turkana requires a broader view that extends beyond the watershed, because competition for water is part of the wider context of KTC; and (iii) power structures and processes associated with the development of water structures are important but poorly understood despite continued resource allocation.
The paper makes four recommendations: (i) catchment management institutions need to take ownership of new developments; (ii) a checklist is provided to achieve more effective outcomes from the siting and design of surface water storage structures; (iii) improve management oversight after completion of projects; and (iv) undertake water-pasture management consultations across the KTC.

Access to sufficient and clean freshwater is essential for all life. Water is also essential for food system functioning: as a key input into food production, but also in processing and preparation, and as a food itself. Water scarcity and pollution are growing, affecting poorer populations, particularly food producers. Malnutrition levels are also on the rise, and this is closely linked to water scarcity. The achievement of Sustainable Development Goal (SDG) 2 and SDG 6 are co-dependent. Solutions to jointly improve food systems and water security outcomes that the United Nations Food Security Summit (UNFSS) should consider include: 1) strengthening efforts to retain water-based ecosystems and their functions; 2) improving agricultural water management for better diets for all; 3) reducing water and food losses beyond the farmgate; 4) coordinating water with nutrition and health interventions; 5) increasing the environmental sustainability of food systems; 6) explicitly addressing social inequities in water-nutrition linkages; and 7) improving data quality and monitoring for water-food system linkages, drawing on innovations in information and communications technology (ICT).

Sustainable development demands reliable water resources, yet traditional water management has broadly failed to avoid environmental degradation and contain infrastructure costs. We explore the global-scale feasibility of combining natural capital with engineering-based (green-gray) approaches to meet water security threats over the 21st century. Threats to water resource systems are projected to rise throughout this period, together with a significant expansion in engineering deployments and progressive loss of natural capital. In many parts of the world, strong path dependencies are projected to arise from the legacy of prior environmental degradation that constrains future water management to a heavy reliance on engineering-based approaches. Elsewhere, retaining existing stocks of natural capital creates opportunities to employ blended green-gray water infrastructure. By 2050, annual engineering expenditures are projected to triple to $2.3 trillion, invested mainly in developing economies. In contrast, preserving natural capital for threat suppression represents a potential $3.0 trillion in avoided replacement costs by mid-century. Society pays a premium whenever these nature-based assets are lost, as the engineering costs necessary to achieve an equivalent level of threat management are, on average, twice as expensive. Countries projected to rapidly expand their engineering investments while losing natural capital will be most constrained in realizing green-gray water management. The situation is expected to be most restrictive across the developing world, where the economic, technical, and governance capacities to overcome such challenges remain limited. Our results demonstrate that policies that support blended green-gray approaches offer a pathway to future global water security but will require a strategic commitment to preserving natural capital. Absent such stewardship, the costs of water resource infrastructure and services will likely rise substantially and frustrate efforts to attain universal and sustainable water security.

The role of hydropower in the renewable energy mix for Africaapos;s green development is widely recognised and underpinned by respective government and development partner funded initiatives. However, the growing demand for energy must be balanced with considerations for resource protection and benefit sharing of water resource developments with vulnerable human communities. An international conference on water stewardship for sustainable hydropower brought together key stakeholders in Nairobi, Kenya. This paper aims to synthesise the key messages of experts who attended the conference, presents the emerging body of good practice policies, plans and action in developing sustainable hydropower in Sub-Saharan Africa, and provides recommendations for the way forward. Outcomes of the conference include considerations, planning for sustainable resource development, resource protection considerations, sharing of resource development benefits, and putting the promise into practice. This discussion describes the nature of our planning and management mistakes in the past, presents good practice options and how to implement sustainable hydropower in the future.

Value chain for development (VCD) has increasingly been promoted for poverty reduction; yet, there is inadequate evidence on its effectiveness. Based on a comprehensive literature review, this article offers reasons why evidence on VCD impacts on poverty reduction is uncertain. It also suggests a conceptual framework for the poor-centred value chain for sustainable development to guide a better analysis of VCD participation and poverty impacts. The framework is particularly useful for researchers involved in research for development related projects in the VCD space. As it provides an analytical lens to understand the broader contextual situation of the poor, co-design solutions with multi-stakeholders and implement appropriate “fit-toneeds” strategies that ensure the poor benefits from their VCD participation. The article contributes to the existing VCD discourse by reflecting on the multidimensional nature and dynamism of poverty reduction, the poorapos;s heterogeneity and their value chain readiness and VCD impacts on poverty.

A necessary extension of the concept of Resource Recovery and Reuse with an even higher priority is the prevention and reduction of waste. One concern, in particular, is food waste, which constitutes the largest share of human waste. Target 12.3 of the United Nations Sustainable Development Goals (SDGs) is to ‘halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses, by 2030’. For this report, over 400 businesses were analyzed to identify common approaches and business models to address the food waste challenge. The business models are presented under seven categories measurement, redistribution, resell, value addition, responsible waste collection, resource recovery, and recycling with a special focus on their application potential to the Global South.
Irrigation represents a long-standing water sector investment in South East Asia. However, despite the undeniable benefits of food production, an irrigation/rice-centric strategy is insufficient in a multi-dimensional conceptualisation of development. The Sustainable Development Goals (SDGs) challenge us to re-think traditional ways of achieving food security. Central to this challenge is how we can retain multi-functionality within landscapes. We explore the often negatively correlated relationship between irrigation and inland fisheries through a literature review and interviews with key informants, focusing on examples from Myanmar and Cambodia. We found that whilst technical options exist for minimizing irrigation impacts on fisheries, there is a fundamental disconnect between the technical application of such ‘solutions’, and distribution of benefits to the marginal groups that SDGs 1, 2, 3 and more target. We found that insufficient recognition of the social contexts in which solutions are applied underpins this disconnect. This means that technical infrastructure design needs to be organised around the question, ‘Who do we want to benefit?’, if investments are to go beyond rice/fish production and deliver more on socially inclusive food security and livelihood opportunities. This paper is a call to extend the framing and financing of irrigation investments beyond technical parameters to include investing in the social processes that enable both multi-functionality and inclusive growth, to enhance the role of irrigation in adapting to a changing climate, while maintaining landscape integrity and multi-functionality so necessary for a sustainable future.

Implementing a circular economy approach to sanitation requires knowledge of the costs to construct, operate and maintain resource-oriented systems. Yet the dearth of data on costs of urban sanitation in general, and resource-oriented systems in particular, limit opportunities to progress sustainable sanitation in low- and middle-income countries. This paper contributes empirical data on the life-cycle costs of a resource-oriented sanitation system in urban Sri Lanka, addressing a gap in evidence about how much it costs, and who pays, for a system that integrates fecal sludge management with nutrient capture and reuse. Costs across the system life-cycle were analyzed according to: (i) cost type; (ii) phases of the sanitation chain; and (iii) distribution between actors. Over a 25-year lifespan, the system had an annualized cost of USD 2.8/person or USD 11/m3 of septage treated. Revenue from co-compost sales covered reuse-related costs plus 8% of present value costs for other phases of the sanitation chain. Findings affirm both the potential for resource-oriented sanitation to generate revenue, and the need for substantial complementary investment in the overall system. The system was found to be reliant on household investment, yet financially viable from the service provider perspective with revenue from desludging services (89%) and co-compost sales (11%) that exceeded costs over the system lifespan and in most years. The analysis of total costs, financial perspectives, and reuse specifics contributes critical evidence to inform policy and planning that supports a purposeful and equitable transition towards circular economy approaches to sanitation.

Worldwide, off-grid solar photovoltaic irrigation is currently being developed with the expectation that it will help secure water access to increase food production, reduce fuel-based carbon emissions and energy costs, and increase human resilience to climate change. In developing countries across the Middle East and North Africa, South East Asia and Sub-Saharan Africa, the adoption of solar technology in agriculture to lift groundwater is rapidly expanding, following decreases in pump costs, economic incentives, and development partner initiatives. Solar irrigation potentially provides a cost-effective and sustainable energy source to secure food production and sustain livelihoods in line with multiple Sustainable Development Goals, but achieving such potential requires improved policies and institutions to coordinate across numerous stakeholders, objectives, and approaches. This paper uses cases and observations from across regions to propose a framework to support policy, regulation, and monitoring for environmentally sustainable and socio-economically inclusive solar irrigation investments. While not exhaustive, the components seek to address the intersection of energy, water and food security, as well as social equity. The paper emphasizes the need for an understanding of how solar irrigation can be scaled to be both accessible for smallholder farmers and environmentally sustainable.

We have one Earth and one water resource defining our living space. We are the key custodians for safeguarding these resources, which underpin the healthy and peaceful environment in which we all want to live. We cannot expand the physical boundaries, but we can stretch our perspectives to achieve water sustainability through global solidarity and considering water inside Earth’s crust: groundwater.

The source-to-sea continuum links the interconnected ecosystems of the water cycle with the associated socioeconomic processes, demands and pressures. Maximizing benefits and protecting existing resources through integrated water management and governance at scale capitalizes on existing institutional and governmental asymmetries by developing an outcome-driven management that builds on existing local, national and transboundary legal frameworks to enhance connectivity. This paper presents how to action this through focusing on three areas of governance: benefit-sharing dialogues for shared visioning; a multi-stakeholder platform to increase coordination in decision-making both up- and downstream; and improved agency coordination between basins and coasts.

This paper outlines a new and integrated water storage agenda for resilient development in a world increasingly characterised by water stress and climate uncertainty and variability.; Storing water has long been a cornerstone of socio-economic development, particularly for societies exposed to large climatic variability. Nature has always supplied the bulk of water storage on earth, but built storage has increased significantly, particularly over the twentieth century. Today, numerous countries suffer from water storage gaps and increasingly variable precipitation, threatening sustainable development and even societal stability. There is a growing need to develop more storage types and manage existing storage better. At the same time, the policy, engineering, and scientific communities may not fully recognise the extent of these storage gaps and how best to manage them. There are large and uncertain costs and benefits of different types of storage, and developing storage can be risky and controversial. Although there is consensus that built and natural storage are fundamentally complementary, there is still no pragmatic agenda to guide future integrated water storage development.; This paper argues that water storage should be recognised as a service rather than only a facility. More than volumes of water stored behind a dam or in a watershed, what ultimately matters is the ability to provide different services at a particular time and place with a given level of assurance. Integrated storage systems should be developed and managed to deliver a targeted service standard. This will reduce the costs of new storage development and make the benefits more sustainable.; As this paper demonstrates, there are numerous data gaps pertaining to water storage, as well as a need for greater clarity on some key concepts. This paper does not introduce new data or research but rather provides a review of some of the current knowledge and issues around water storage, and outlines a new, integrated and constructive water storage agenda for the decades to come.

Infrastructure investment is one of the main preconditions for enabling developing countries to accelerate or sustain the pace of their development and achieve the Sustainable Development Goals. This paper examines the determinants of agricultural water infrastructure investments in the Kingdom of Eswatini. Using annual data (time series); Pearson Pair-wise Correlation, Unit-root tests and OLS regression techniques are applied to determine the relationship between public infrastructure investment and factors that influence public investments. Agricultural water infrastructure investment is found to be positively correlated to GDP, Sugar export income and FDI into agriculture. Past economic growth and sugar export values are the two critical determinants of agricultural water infrastructure investments in Eswatini. It can be safely construed that higher incomes as well as terms of trade for sugar, can improve spending on agriculture water investments. This is important because an increase in investments in water infrastructure may then help spur economic growth.

The Nexus Approach to environmental resources management is increasingly recognized as an important vehicle to achieve sustainability as spelled out in the Sustainable Development Goals (SDGs). In particular, it was argued that the Nexus Approach is key for the sustainable use of environmental resources under conditions of global change and provides a tool to deal with challenges of global change including climate change, urbanization and population growth. Building on conceptual considerations with regard to monitoring and implementation outlined earlier, here, we explore how the Nexus Approach may provide solutions for managing resources in multifunctional land-use systems and resilient cities. In fact, the resources perspective is essential for holistic management of water, soil and waste along the urbanrural axis. Peri-urban areas provide perfect examples of multifunctional systems with manyfold opportunities to closing cycles, improve resource efficiency and mitigate trade-offs. Cases described in this book provide both positive as well as negative examples of what can be achieved by applying nexus thinking and what goes wrong if you don’t. Key messages emerging include: (i) participatory approaches are a central element for successful implementation of a nexus approach, (ii) effective mechanisms of knowledge transfer are a prerequisite of adoption and upscaling of nexus approaches and (iii) the lack of economic incentives and lack of data represent major challenges for the implementation of a nexus approach. Overall, the importance of a nexus mindset of all stakeholders involved in nexus cases and of providing an enabling environment by nexus-oriented governance, including appropriate economic instruments, was confirmed.

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.

In 2019, Sri Lanka introduced two policies that referred to food waste and the need to reduce it. To understand key stakeholders’ readiness in this context, this study analyzed the food waste perceptions of private and public sectors in Colombo (open markets, supermarkets, hotels, restaurants, canteens, food caterers and key authorities). Interviews were carried out with operational managers and public officials, as well as other stakeholders who have roles in food waste redistribution and reuse, such as NGOs and the livestock sector. So far, the food-waste-related policy recommendations lack an operational inter-institutional home which can build on measures, like standards, regulations and incentives. Thus, most food waste reduction initiatives are initiated by NGOs or by the private sector, e.g., by larger hotels and supermarket chains. These entities were ready to lead by example, based on the understanding that urban food waste is an internal (financial) management challenge. Among smaller local entities, food waste was perceived more as an external issue to be handled by the city’s waste collection services. Although perceptions varied between entities generating smaller or larger quantities of food waste, there was general agreement that suboptimal capacities and mechanisms to quantify, monitor and cost food waste generation appeared to be obstacles for in-depth awareness creation and action. There was significant interest in communication platforms for cross-sectoral learning, win/win collaborations with reliable collection (reuse) services that are currently operational, such as those provided by piggeries, as well as surplus redistribution initiatives if food safety and related liabilities can be addressed effectively.

Globally, 50% of the population relies on on-site sanitation systems (OSS) such as septic tanks and pit latrines and is, hence, in need of Fecal Sludge Management (FSM) solutions. India is a classic example, given that its government built more than 100 million toilets with the majority relying on OSS. With 400 fecal sludge treatment plants (FSTPs) in various stages of planning, procurement and construction, this report comes at an opportune time to present findings on FSM business models already implemented across India.
Interviews were conducted with a total of 105 Emptying and Transport (Eamp;T) operators in 72 towns and cities across 16 states in India, 22 representatives from municipalities that own emptying vehicles, 18 FSTP operators and more than 30 institutions. In addition, procurement tenders for Eamp;T and FSTPs in 13 states were analyzed.
In total, 18 business models were identified, several with energy or nutrient recovery components. The analysis of Eamp;T operators revealed clear differences that steer a business towards success or failure. The majority of operators still dispose fecal sludge in an unsafe manner, due to the lack of official disposal or treatment sites. In comparison to sewer networks, the capital and operating costs (per capita) of FSTPs were significantly lower. The report provides evidence-based discussions on policies and recommendations for scaling and sustaining FSM.
While water security is widely regarded as an issue of global significance and concern, there is not yet a consensus on a methodology for evaluating it. The difficulty in operationalizing the concept comes from its various interpretations and characteristics at different spatial and temporal scales. In this paper, we generate a dashboard comprised of 52 indicators to facilitate a rapid assessment of a country’s water security and to focus the first step of a more comprehensive water security diagnostic assessment. We design the dashboard around a conceptualization of water security that builds upon existing framings and metrics. To illustrate its usefulness, we apply the dashboard to a case study of Pakistan and a regional cross-country comparative analysis. The dashboard provides a rapid view of the water security status, trends, strengths, and challenges for Pakistan. The cross-country comparative analysis tentatively identifies relationships between indicators such as water stress and the transboundary dependency ratio, with countries exhibiting high values in both variables being especially vulnerable to transboundary water risk. Overall, this dashboard (1) provides quantitative information on key water-related variables at the country level in a consistent manner and (2) helps to design and focus more in-depth water security diagnostic studies.

The Sustainable Development Goals (SDGs) purport to report holistically on progress towards sustainability and do so using more than 231 discrete indicators, with a primary objective to achieve a balance between the environment, social and economic aspects of development. The research question underpinning the analyses presented in this paper is: are the indicators in the SDGs sufficient and fit for purpose to assess the trajectory of natural resources towards sustainability? We extracted the SDG indicators that monitor the state of natural resources, or alternately support policy or governance for their protection, and determined whether these are adequate to provide the essential data on natural resources to achieve the aims of the SDGs. The indicators are clustered into four natural resource categoriesland, water (both marine and freshwater), air and biodiversity. Indicators for monitoring land resources show that the most comprehensive land resource indicator for degraded land is not fully implemented and that missing from land monitoring is an evaluation of vegetation health outside of forests and mountains, the condition of soils, and most importantly the overall health of terrestrial ecosystems. Indicators for monitoring water resources have substantial gaps, unable to properly monitor water quality, water stress, many aspects of marine resources and, most significantly, the health of fresh and salt water ecosystems. Indicators for monitoring of air have recently become more comprehensive, but linkage to IPCC results would benefit both programs. Monitoring of biodiversity is perhaps the greatest weakness of the SDG Agenda, having no comprehensive assessment even though narrow aspects are monitored. Again, deliberate linkages to other global biodiversity programs (e.g., CBD and the Post-2020 Biodiversity Framework, IPBES, and Living Planet) are recommended on condition that data can be defined at a country level. While the SDG list of indicators in support of natural resource is moderately comprehensive, it lacks holistic monitoring in relation to evaluation of ecosystems and biodiversity to the extent that these missing but vital measures of sustainability threaten the entire SDG Agenda. In addition, an emerging issue is that even where there are appropriate indicators, the amount of country-level data remains inadequate to fully evaluate sustainability. This signals the delicate balance between the extent and complexity of the SDG Agenda and uptake at a country level.

A key question in sustainable development is how much alteration in natural systems, such as river basins, is acceptable? One of the ways by which humans alter a river basin is by building water storage infrastructure. While storage reservoirs deliver numerous benefits, they can also induce social and environmental costs by displacing people, fragmenting river networks and altering downstream flow regimes. In such a context, merely capping total water withdrawal from rivers for human consumption is not sufficient. River basin plans should also identify optimal (acceptable) limits to surface storage capacities, and optimal numbers, degrees of distribution and locations of storage infrastructure. It remains largely unclear, however, whether it is possible to define a hydrologically, ecologically and socially justified ‘surface water storage boundary’ for a river basin. An associated question is what would be the ‘best’ arrangement of this bounding storage capacity in the basins river network (in terms of numbers, sizes and locations of reservoirs) to maximize water storage benefits and minimize environmental and social costs. The main objective of this review is to examine contemporary knowledge on surface water storage development with a focus on tools and approaches that may help to answer the above questions of a ‘surface water storage boundary’ and its ‘optimum arrangement’ for a river basin. In order to achieve this objective, our review introduces two novel concepts: the ‘storage scale’ and the ‘sustainable storage development framework.’ The ‘storage scale’ has four elements capacity, number, distribution and location individual scales that help visualize a ‘surface water storage boundary’ and its ‘optimum arrangement’ for a typical river basin. The ‘sustainable storage development framework’ consists of three dimensions economic benefits, ecosystems and society- and a set of indicators quantifying each dimension. This review shows that optimal levels of the elements of the ‘storage scale’ may be identified using the ‘sustainable storage development framework’.

Water security has emerged in the 21st century as a powerful construct to frame the water objectives and goals of human society and to support and guide local to global water policy and management. Water security can be described as the fundamental societal goal of water policy and management. This article reviews the concept of water security, explaining the differences between water security and other approaches used to conceptualize the water-related challenges facing society and ecosystems and describing some of the actions needed to achieve water security. Achieving water security requires addressing two fundamental challenges at all scales: enhancing water’s productive contributions to human and ecosystems’ well-being, livelihoods and development, and minimizing water’s destructive impacts on societies, economies, and ecosystems resulting, for example, from too much (flood), too little (drought) or poor quality (polluted) water.

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 6293% 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.

The world is not on track to achieve Sustainable Development Goal 6 on clean water and sanitation by 2030. We urge a rapid change of the economics, engineering and management frameworks that guided water policy and investments in the past in order to address the water challenges of our time.

The missing link between cross-sectoral resource management and full-scale adoption of the water-energy-food (WEF) nexus has been the lack of analytical tools that provide evidence for policy and decision-making. This study defined WEF nexus sustainability indicators, from where an analytical model was developed to manage WEF resources in an integrated manner using the Analytic Hierarchy Process (AHP). The model established quantitative relationships among WEF sectors, simplifying the intricate interlinkages among resources, using South Africa as a case study. A spider graph was used to illustrate sector performance as related to others, whose management is viewed either as sustainable or unsustainable. The model was then applied to assess progress towards the Sustainable Development Goals in South Africa. The estimated integrated indices of 0.155 and 0.203 for 2015 and 2018, respectively, classify South Africa’s management of resources as marginally sustainable. The model is a decision support tool that highlights priority areas for intervention.

Monitoring the qualitative status of freshwaters is an important goal of the international community, as stated in the Sustainable Development Goal (SDGs) indicator 6.3.2 on good ambient water quality. Monitoring data are, however, lacking in many countries, allegedly because of capacity challenges of less-developed countries. So far, however, the relationship between human development and capacity challenges for water quality monitoring have not been analysed systematically. This hinders the implementation of fine-tuned capacity development programmes for water quality monitoring. Against this background, this study takes a global perspective in analysing the link between human development and the capacity challenges countries face in their national water quality monitoring programmes. The analysis is based on the latest data on the human development index and an international online survey amongst experts from science and practice. Results provide evidence of a negative relationship between human development and the capacity challenges to meet SDG 6.3.2 monitoring requirements. This negative relationship increases along the course of the monitoring process, from defining the enabling environment, choosing parameters for the collection of field data, to the analytics and analysis of five commonly used parameters (DO, EC, pH, TP and TN). Our assessment can be used to help practitioners improve technical capacity development activities and to identify and target investment in capacity development for monitoring.

Data exchange in transboundary waters is fundamental to advance cooperative water management. Nonetheless, the degree to which data are shared is not well understood. To gauge this degree, an assessment framework was developed and applied in 25 international river basins. The framework captures the degree to which a set of data parameters is exchanged among countries. A reasonable proportion of surveyed basins exchange some data, but the breadth of such exchange is often limited, and not regular. This paper highlights where data exchange can be improved and provides guidance on how indicators used in global assessment frameworks can motivate this improvement.

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 surfacegroundwater 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.

The challenge of sustainable development is enshrined in the ambitious 2030 Agenda for Sustainable Development of the United Nations. The 17 goals and its various targets are unique with water being one of the cross cutting themes. Taking examples of past water dependent societies in a comparative setting, this paper challenges the new field of Archaeo-hydrology in how it could contribute to the 2030 Agenda based on what can be learned from past and contemporary water dependent societies. We find that societies have coped with climate variability by diversifying both in occupation, livelihoods and use of space. Sharing the costs of coordinating such diversification requires inclusive institutions and technological innovations. Similar to technology, new social institutions emerge in response to a changing environment. However, in tandem, slow out-migration of people seems to go on, driven by better livelihood opportunities outside. If technological innovation and institutional evolution are not rapid enough, then migration seems to take over as the adaptive mechanism in response to environmental changes resulting in rapid dispersal. This means that migration from smaller, less endowed societies can be expected to be rapid, with repetitive cycles of abandonment and rehabilitation after each critical climate or adverse environment events. Consequently, more place based local innovations should be encouraged and local economies should be diversified to increase the resilience so that vulnerable societies may inherit favourable know-how for a sustainable future under changing climatic conditions.

There is increasing recognition of the need to bring about changes across the full spectrum of agricultural practices to ensure that, in future, food production systems are more diverse, sustainable and resilient. In this context, the objectives of irrigation need to be much more ambitious, shifting away from simply maximizing crop yields to maximizing net benefits across a range of uses of irrigation water, including ecosystems and nature-based solutions. One important way to achieve this is by better integrating fisheries into the planning, design, construction, operation and management of irrigation systems. Irrigation a major contributor to the Green Revolution has significantly improved agricultural production worldwide, with consequent benefits for food security, livelihoods and poverty alleviation. Today, irrigated agriculture represents about 21 percent of cultivated land, but contributes approximately 40% of the total global crop production. Many governments continue to invest in irrigation as a cornerstone of food security and rural development. Investments in irrigation often represent a pragmatic form of adaptation to changing climatic conditions. This guide focuses on how to sustainably optimize and broaden the range of benefits from irrigation development - not only economic but also social and environmental benefits. It emphasizes the opportunities that fisheries could provide to increase food production and economic returns, enhance livelihoods and public health outcomes, and maintain key ecosystem services. The guide considers possible trade-offs between irrigation and fisheries, and provides recommendations on how these could be minimized.

An effective placement of irrigation efficiency in water management will contribute towards meeting the pre-eminent global water challenges of our time such as addressing water scarcity, boosting crop water productivity and reconciling competing water needs between sectors. However, although irrigation efficiency may appear to be a simple measure of performance and imply dramatic positive benefits, it is not straightforward to understand, measure or apply. For example, hydrological understanding that irrigation losses recycle back to surface and groundwater in river basins attempts to account for scale, but this generalisation cannot be readily translated from one location to another or be considered neutral for farmers sharing local irrigation networks. Because irrigation efficiency (IE) motives, measures, effects and technologies play out at different scales for different people, organisations and purposes, and losses differ from place to place and over time, IE is a contested term, highly changeable and subjective. This makes generalisations for science, management and policy difficult. Accordingly, we propose new definitions for IE and irrigation hydrology and introduce a framework, termed an ‘irrigation efficiency matrix’, comprising five spatial scales and ten dimensions to understand and critique the promises, pitfalls and paradoxes of IE and to unlock its utility for addressing contemporary water challenges.

Rice and fish are preferred foods, critical for healthy and nutritious diets, and provide the foundations of local and national economies across Asia. Although transformations, or “revolutions,” in agriculture and aquaculture over the past half-century have primarily relied upon intensified monoculture to increase rice and fish production, agroecological approaches that support biodiversity and utilize natural processes are particularly relevant for achieving a transformation toward food systems with more inclusive, nutrition-sensitive, and ecologically sound outcomes. Rice and fish production are frequently integrated within the same physical, temporal, and social spaces, with substantial variation amongst the types of production practice and their extent. In Cambodia, rice field fisheries that strongly rely upon natural processes persist in up to 80% of rice farmland, whereas more input and infrastructure dependent rice-shrimp culture is expanding within the rice farmland of Vietnam. We demonstrate how a diverse suite of integrated production practices contribute to sustainable and nutrition-sensitive food systems policy, research, and practice. We first develop a typology of integrated production practices illustrating the nature and degree of: (a) fish stocking, (b) water management, (c) use of synthetic inputs, and (d) institutions that control access to fish. Second, we summarize recent research and innovations that have improved the performance of each type of practice. Third, we synthesize data on the prevalence, outcomes, and trajectories of these practices in four South and Southeast Asian countries that rely heavily on fish and rice for food and nutrition security. Focusing on changes since the food systems transformation brought about by the Green Revolution, we illustrate how integrated production practices continue to serve a variety of objectives to varying degrees: food and nutrition security, rural livelihood diversification and income improvement, and biodiversity conservation. Five shifts to support contemporary food system transformations [i.e., disaggregating (1) production practices and (2) objectives, (3) utilizing diverse metrics, (4) valuing emergent, place-based innovation, (5) building adaptive capacity] would accelerate progress toward Sustainable Development Goal 2, specifically through ensuring ecosystem maintenance, sustainable food production, and resilient agricultural practices with the capacity to adapt to global change.

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.

There is a proactive interest in recovering water, nutrients and energy from waste streams with the increase in municipal wastewater volumes and innovations in resource recovery. Based on the synthesis of wastewater data, this study provides insights into the global and regional “potential” of wastewater as water, nutrient and energy sources while acknowledging the limitations of current resource recovery opportunities and promoting efforts to fast-track highefficiency returns. The study estimates suggest that, currently, 380 billion m3 (m3 = 1,000 L) of wastewater are produced annually across the world which is a volume fivefold the volume of water passing through Niagara Falls annually. Wastewater production globally is expected to increase by 24% by 2030 and 51% by 2050 over the current level. Among major nutrients, 16.6 Tg (Tg = million metric ton) of nitrogen are embedded in wastewater produced worldwide annually; phosphorus stands at 3.0 Tg and potassium at 6.3 Tg. The full nutrient recovery from wastewater would offset 13.4% of the global demand for these nutrients in agriculture. Beyond nutrient recovery and economic gains, there are critical environmental benefits, such as minimizing eutrophication. At the energy front, the energy embedded in wastewater would be enough to provide electricity to 158 million households. These estimates and projections are based on the maximum theoretical amounts of water, nutrients and energy that exist in the reported municipal wastewater produced worldwide annually. Supporting resource recovery from wastewater will need a step-wise approach to address a range of constraints to deliver a high rate of return in direct support of Sustainable Development Goals (SDG) 6, 7 and 12, but also other Goals, including adaptation to climate change and efforts in advancing “netzero” energy processes towards a green economy.

About 60% of southern Africa’s population lives in rural areas with limited access to basic services and amenities such as clean and safe water, affordable and clean energy, and balanced and nutritious diets. Resource scarcity has direct and indirect impacts on nutrition, human health, and well-being of mostly poor rural communities. Climate change impacts in the region are manifesting through low crop yields, upsurge of vector borne diseases (malaria and dengue fever), and water and food-borne diseases (cholera and diarrhoea). This study applied a waterenergyfood (WEF) nexus analytical livelihoods model with complex systems understanding to assess rural livelihoods, health, and well-being in southern Africa, recommending tailor-made adaptation strategies for the region aimed at building resilient rural communities. The WEF nexus is a decision support tool that improves rural livelihoods through integrated resource distribution, planning, and management, and ensures inclusive socio-economic transformation and development, and addresses related sustainable development goals, particularly goals 2, 3, 6 and 7. The integrated WEF nexus index for the region was calculated at 0.145, which is marginally sustainable, and indicating the region’s exposure to vulnerabilities, and reveals a major reason why the region fails to meet its developmental targets. The integrated relationship among WEF resources in southern Africa shows an imbalance and uneven resource allocation, utilisation and distribution, which normally results from a ‘siloed’ approach in resource management. The WEF nexus provides better adaptation options, as it guides decision making processes by identifying priority areas needing intervention, enhancing synergies, and minimising trade-offs necessary for resilient rural communities. Our results identified (i) the trade-offs and unintended negative consequences for poor rural households’ livelihoods of current silo approaches, (ii) mechanisms for sustainably enhancing household water, energy and food security, whilst (iii) providing direction for achieving SDGs 2, 3, 6 and 7.

Irrigation has been, and will remain, instrumental in addressing water security (Sustainable Development Goal (SDG) 6), food insecurity (SDG 2) and poverty (SDG 1) goals. However, the global context in which irrigation takes place is changing rapidly. A call for healthier and more sustainable food systems is placing new demands on how irrigation is developed and managed. Growing pressures from competing water uses in the domestic and industrial sectors, as well increasing environmental awareness, mean irrigation is increasingly called on to perform better, delivering acceptable returns on investment and simultaneously improving food security, rural livelihoods and nutrition, as well as supporting environmental conservation. Better integration of fisheries (including aquaculture) in irrigation planning, investment and management can contribute to the modernisation of irrigation and the achievement of the multiple objectives that it is called on to deliver. A framework illustrating how fisheries can be better integrated with irrigation, and how the two can complement each other across a range of scales, from scheme to catchment and, ultimately, national level, is presented.
Irrigated agriculture and inland fisheries both make important contributions to food security, nutrition, livelihoods and wellbeing. Typically, in modern irrigation systems, these components operate independently. Some practices, commonly associated with water use and intensification of crop production can be in direct conflict with and have adverse effects on fisheries. Food security objectives may be compromised if fish are not considered in the design phases of irrigation systems. The 2030 Agenda for Sustainable Development provides a framework that can serve as a backdrop to help integrate both sectors in policy discussions and optimise their contributions to achieving the Sustainable Development Goals (SDGs). Inland fisheries systems do play an important role in supporting many SDG objectives, but these contributions can sometimes be at odds with irrigated agriculture. Using case studies of two globally important river catchments, namely the Lower Mekong and MurrayDarling basins, we highlight the conflicts and opportunities for improved outcomes between irrigated agriculture and inland fisheries. We explore SDG 2 (Zero Hunger) as a path to advance our irrigation systems as a means to benefit both agriculture and inland fisheries, preserving biodiversity and enhancing the economic, environmental and social benefits they both provide to people.

In low- and middle-income countries, the management of fecal sludge from on-site sanitation systems has received little attention over many decades, resulting in insufficient or missing regulations to guide investments and management options. To address this gap, this report examines existing and emerging guidelines and regulations for fecal sludge management (FSM) along the sanitation service chain (user interface, containment, emptying, transport, treatment, valorization, reuse or disposal). It also draws empirical examples from guidelines across the globe to support policy-makers, planners, and sanitation and health officers, as well as consultants in low- and middle-income countries in the development and design of local and national FSM guidelines and regulations.

The United Nations 2030 Agenda for Sustainable Development promises to achieve change in almost every aspect of life on Earth. Encompassing 17 Sustainable Development Goals (SDGs) and 169 targets, the Agenda marks the first time in history when all nations have agreed on how to chart their future. The SDGs are not just a global reporting exercise, however, but rather involve a global program that embraces country-led efforts. Guided by the ideas contained in the 2030 Agenda, each nation must seek to become more prosperous and sustainable, while contributing to the global effort at the same time. If all the countries achieve this, we will have a sustainable planet and a secure future for all.
This document offers guidance on how developing countries can adapt the SDGs to their own contexts and priorities. It indicates important areas for developing countries to consider when creating their own program to achieve the SDGs, and provides examples of success to demonstrate concrete possibilities for progress.

However, unprecedented and accelerating drivers such as climate change, population growth, and land degradation make agricultural water management a more urgent priority than ever before. In addition, as part of the 2030 UN Agenda for Sustainable Development, Arab countries have committed to work towards an ambitious set of development targets, the Sustainable Development Goals (SDGs). Unless the right policies and investments are put in place, it will be difficult to achieve the SDGs, including ending hunger and providing clean water and sanitation for all.
This paper is part of an ongoing collaboration between the Food and Agriculture Organization of the United Nations (FAO) and the International Water Management Institute to foster dialogue on agricultural water policies and investments in the context of the FAO led Regional Water Scarcity initiative. The purpose of the paper is to frame the key challenges and opportunities in the sector including emerging innovations in digital agriculture, water accounting, water supply and wastewater reuse and to lay out broad strategic directions for action.

The paper discussed motivations of sustainable entrepreneurship in Gauteng Province, South Africa, and estimated relationships between these motivations and enterprise performance. Despite the growing field of sustainable entrepreneurship, most of the available literature has been mainly theoretical and qualitative or has focused on developed countries. This paper contributes to addressing this gap through empirical analysis based on primary survey data from 91 sustainable entrepreneurs. Reliability of the performance and motivation scales were subjected to the Cronbachapos;s alpha coefficient test, and the results were acceptable. The exploratory factor analysis indicated that the motivations of sustainable entrepreneurship factored into 4 dimensions: extrinsic, intrinsic, income security and financial independence, and necessity motivations. Regression analysis revealed that extrinsic and intrinsic motivations are important determinants of enterprise performance. These motivations can be targeted to promote sustainable entrepreneurship in addition to complementary support such as improving business management skills and competencies of sustainable entrepreneurs.

WaterSanitationHygiene (WASH) remains vital for the 2030 Agenda for Sustainable Development, yet many countries have not localised the 17 Sustainable Development Goals (SDGs), including SDG 6, which focuses on ensuring the availability and sustainable management of water and sanitation for all. Even in leading African economies such as South Africa, many communities still use the bucket system for sanitation. Using a Composite Index drawn from three indicators whose data were available for 53 of the 54 African countries, it emerged that these states are at various stages of fulfilling the targets set out in SDG 6. The fact that some countries showed declining trends in WASH between 2000 and 2015, is an indication that it will be difficult for Africa to reach the 2030 targets. We recommend that Africa aggressively mobilise resources if it is to attain universal WASH services by 2030, along with other SDG 6-related targets.

Agricultural land suitability analysis (ALSA) for crop production is one of the key tools for ensuring sustainable agriculture and for attaining the current global food security goal in line with the Sustainability Development Goals (SDGs) of United Nations. Although some review studies addressed land suitability, few of them specifically focused on land suitability analysis for agriculture. Furthermore, previous reviews have not reflected on the impact of climate change on future land suitability and how this can be addressed or integrated into ALSA methods. In the context of global environmental changes and sustainable agriculture debate, we showed from the current review that ALSA is a worldwide land use planning approach. We reported from the reviewed articles 69 frequently used factors in ALSA. These factors were further categorized in climatic conditions (16), nutrients and favorable soils (34 of soil and landscape), water availability in the root zone (8 for hydrology and irrigation) and socio-economic and technical requirements (11). Also, in getting a complete view of crop’s ecosystems and factors that can explain and improve yield, inherent local socio-economic factors should be considered. We showed that this aspect has been often omitted in most of the ALSA modeling with only 38% of the total reviewed article using socio-economic factors. Also, only 30% of the studies included uncertainty and sensitivity analysis in their modeling process. We found limited inclusions of climate change in the application of the ALSA. We emphasize that incorporating current and future climate change projections in ALSA is the way forward for sustainable or optimum agriculture and food security. To this end, qualitative and quantitative approaches must be integrated into a unique ALSA system (Hybrid Land Evaluation System - HLES) to improve the land evaluation approach.

With rapidly increasing investment in water control infrastructure (WCI) and a recently ratified agriculture development strategy that promotes integrated farming of high-value products such as fish, agricultural production, already fundamental to Myanmar’s economy, will be central to driving the countries’ socioeconomic transformation. Water planners and managers have a unique opportunity to design and manage WCI to incorporate fish and, in so doing, reduce conflicts and optimise the benefits to both people and the ecosystem services upon which they depend. Results from ricefish culture experimental trials in Myanmar’s Ayeyarwady Delta are providing an evidence base for the importance of integrating fish into WCI, highlighting a range of both environmental and social benefits. By using less than 13% of paddy land area and through best management practices, existing rice productivity is sustained, alongside a 25% increase in economic returns for the same land area from fish. In addition, there are considerably more protein and micronutrients available from the fish produced in the system. Should these farming system innovations be adopted at scale, Myanmar stands to benefit from increased employment, incomes and nutritional value of farm plots (alongside associated reductions in pesticide pollution) and water use benefits.

Diarrhoea caused by waterborne pathogens still has a large burden of disease. We introduce a modelling and scenario analysis framework that enables better understanding of sources of and possible future changes in the disease burden due to environmental change and management implementation. The state-of-the-art research that can contribute to the development of the framework at the large scale is analysed, together with research gaps and opportunities for future research. Priorities have been identified and these include implementation of Quantitative Microbial Risk Assessment and application of the models in scenario analyses. The credibility of the model outputs should be central in the analysis, for example by developing stochastic models. Implementation of the framework contributes towards achieving the Sustainable Development Goals.

Prioritising aviral dhara (uninterrupted flow) over nirmal dhara (unpolluted flow) can deliver quick outcomes in the Namami Gange Programme. Treating human, municipal and industrial waste released into the Ganga is a long-term project requiring vast resources and political energy, besides behavioural change on a mass scale. But, Ganga’s dry season flows can be quickly improved by basin-scale conjunctive management of the surface water and groundwater. Irrigation in the Ganga basin today depends on tubewells far more than canals. A multipronged protocol is outlined to manage the old canal network and new hydropower storages in order to maximise irrigation benefits and improve dry season river flows.

Billions of people currently lack clean water and sanitation. By 2050 the global population will have grown to nearly 10 billion, over two-thirds of whom will live in urban areas. This Voices asks: what are the research and water-management priorities to ensure clean water and sanitation in the world’s cities?

The 2030 Agenda for Sustainable Development, the Sustainable Development Goals (SDGs), are high on the agenda for most countries of the world. In its publication of the SDGs, the UN has provided the goals and target descriptions that, if implemented at a country level, would lead towards a sustainable future. The IAEG (InterAgency Expert Group of the SDGs) was tasked with disseminating indicators and methods to countries that can be used to gather data describing the global progress towards sustainability. However, 2030 Agenda leaves it to countries to adopt the targets with each government setting its own national targets guided by the global level of ambition but taking into account national circumstances. At present, guidance on how to go about this is scant but it is clear that the responsibility is with countries to implement and that it is actions at a country level that will determine the success of the SDGs. Reporting on SDGs by country takes on two forms: i) global reporting using prescribed indicator methods and data; ii) National Voluntary Reviews where a country reports on its own progress in more detail but is also able to present data that are more appropriate for the country. For the latter, countries need to be able to adapt the global indicators to fit national priorities and context, thus the global description of an indicator could be reduced to describe only what is relevant to the country. Countries may also, for the National Voluntary Review, use indicators that are unique to the country but nevertheless contribute to measurement of progress towards the global SDG target. Importantly, for those indicators that relate to the security of natural resources security (e.g., water) indicators, there are no prescribed numerical targets/standards or benchmarks. Rather countries will need to set their own benchmarks or standards against which performance can be evaluated. This paper presents a procedure that would enable a country to describe national targets with associated benchmarks that are appropriate for the country. The procedure builds on precedent set in other countries but in particular on a procedure developed for the setting of Resource Quality Objectives in South Africa. The procedure focusses on those SDG targets that are natural resource-security focused, for example, extent of water-related ecosystems (6.6), desertification (15.3) and so forth, because the selection of indicator methods and benchmarks is based on the location of natural resources, their use and present state and how they fit into national strategies.

Target 6.4 of the recently adopted Sustainable Development Goals (SDGs) deals with the reduction of water scarcity. To monitor progress towards this target, two indicators are used: Indicator 6.4.1 measuring water use efficiency and 6.4.2 measuring the level of water stress (WS). This paper aims to identify whether the currently proposed indicator 6.4.2 considers the different elements that need to be accounted for in a WS indicator. WS indicators compare water use with water availability. We identify seven essential elements: 1) both gross and net water abstraction (or withdrawal) provide important information to understand WS; 2) WS indicators need to incorporate environmental flow requirements (EFR); 3) temporal and 4) spatial disaggregation is required in a WS assessment; 5) both renewable surface water and groundwater resources, including their interaction, need to be accounted for as renewable water availability; 6) alternative available water resources need to be accounted for as well, like fossil groundwater and desalinated water; 7) WS indicators need to account for water storage in reservoirs, water recycling and managed aquifer recharge. Indicator 6.4.2 considers many of these elements, but there is need for improvement. It is recommended that WS is measured based on net abstraction as well, in addition to currently only measuring WS based on gross abstraction. It does incorporate EFR. Temporal and spatial disaggregation is indeed defined as a goal in more advanced monitoring levels, in which it is also called for a differentiation between surface and groundwater resources. However, regarding element 6 and 7 there are some shortcomings for which we provide recommendations. In addition, indicator 6.4.2 is only one indicator, which monitors blue WS, but does not give information on green or green-blue water scarcity or on water quality. Within the SDG indicator framework, some of these topics are covered with other indicators.

Study region : Transboundary aquifers (TBAs) of Africa.; Study focus: Review of work on TBAs in Africa, including an overview of assessments and management efforts that have taken place over the last half century.; New hydrological insights : Seventy-two TBAs have been mapped in Africa. They underlie 40% of the continent, where 33% of the population lives, often in arid or semi-arid regions. TBA inventories have progressed since 2000 and remain work in progress. Despite their importance only eleven TBAs have been subjected to more detailed studies. Cooperation has been formalised for seven TBAs. Most of these TBAs are in North Africa and the Sahel. The recent global Transboundary Waters Assessment Programme compiled information at the national level to describe TBAs in terms of key indicators related to the water resource, socio-economic, and legal and institutional conditions. Availability of data at national level is low, hampering regional assessment. Comparing indicators, from questionnaire surveys, with those from a global water-use model showed variable levels of agreement, calling for further research. Reports on agreements scoping TBA management, indicate that this may be dealt with within international river/lake agreements, but reported inconsistencies between TBA sharing countries also indicate that implementation is limited. Increasing awareness and support to joint TBA management is noticeable amongst international organisations. However, such cooperation requires long-term commitment to produce impacts at the local level.

The discourse on the need for water, energy, and food security has dominated the development agenda of southern African countries, centred on improving livelihoods, building resilience, and regional integration. About 60% of the population in the Southern African Development Community (SADC) live in rural areas relying mainly on rainfed agriculture, lacking access to clean water and energy, yet the region is endowed with vast natural resources. The water-energy-food (WEF) nexus is a conceptual framework that presents opportunities for greater resource coordination, management, and policy convergence across sectors. This is particularly relevant in the SADC region as resources are transboundary and supports efforts linked to regional integration and inclusive socio-economic development and security. We conducted an appraisal of WEF-related policies and institutions in SADC and identified linkages among them. The present ‘silo’ approach in resource management and allocation, often conducted at the national level, contributes to the region’s failure to meet its development targets, exacerbating its vulnerabilities. The lack of coordination of WEF nexus synergies and trade-offs in planning often threatens the sustainability of development initiatives. We highlighted the importance of the WEF nexus to sustainably address the sectoral coordination of resources through harmonised institutions and policies, as well as setting targets and indicators to direct and monitor nexus developments. We illustrate the significance of the nexus in promoting inclusive development and transforming vulnerable communities into resilient societies. The study recommends a set of integrated assessment models to monitor and evaluate the implementation of WEF nexus targets. Going forward, we propose the adoption of a regional WEF nexus framework.

What gets measured gets done! This saying implies that without quantifying what needs to be done, doing it may not be possible. This term is relevant to how African countries will implement the United Nations (UN) Sustainable Development Goals (SDGs) by 2030, particularly in tracking progress on SDG 5 on gender equality and the empowerment of women and girls. During the Millennium Development Goals (MDGs), governments failed to establish baselines for measuring progress in meeting the goals. To ensure that no country is left behind, the UN came up with a list of indicators (Tiers 1-3) for tracking progress in achieving SDGs targets. Tier 1 indicators fall in conventional data sets and almost all countries have these data. The process for implementation, through domestication and localisation by countries, includes the responsibilities of reporting, tracking and monitoring. The article highlights the importance of attempts to establish a broad baseline of data on women in Africa. An Afro-barometer, drawing from UN Tier 1 indicators and using a composite index and data drawn from the World Development Indicators (WDI), is a tentative step towards a baseline for tracking progress towards achieving SDG 5 in Africa. The research established data for 52 of the 54 African countries on women for three indicators, namely: women’s political representation, maternal mortality rates and women’s labour force participation. The gaps in the available data, places a question mark over the capacity and will to measure key indicators of gender inequality by countries. Implementation and reporting is integral to the achievement of the SDGs as well as the African Agenda 2063 and call for political will and resources on the continent to move from the merely aspirational, towards the transformation that the agendas propose.

Sustainable development has become the main focus of the global development agenda as presented in the 2015 Sustainable Development Goals (SDGs). However, for countries to assess progress, they need to have reliable baseline indicators. Therefore, the objective of this paper is to develop a composite baseline index of the agriculture-related SDGs in Southern Africa to guide progress reporting. The paper identified eight of the SDG indicators related to the agriculture sector. The paper relies on data for indicators from five SDGs (SDGs 1, 2, 6, 7 and 15). Applying the arithmetic mean method of aggregation, an agriculture-related SDG composite index for Southern Africa between zero (0 = poor performance) and 100 (best possible performance) was computed for thirteen countries that had data on all identified indicators. The results show that the best performing countries (Botswana, Angola, Namibia, Zambia and South Africa) in the assessment recorded high scores in SDGs 1, 2 and 7. The three countries (Democratic Republic of Congo, Zimbabwe and Madagascar) that performed poorly on both SDG 1 and 2 also had the least scores on the overall agriculture-related SDG composite index. The water stress indicator for SDG 6 recorded the worst performance among most countries in the region. Possible approaches to improve the contribution of agriculture to SDGs may include investing more resources in priority areas for each agriculture-related SDG depending on baseline country conditions. The implementation, monitoring and evaluation of regional and continental commitments in the agriculture sector and the SDGs are critical for achievement of the targets at the national and local levels. While the methods employed are well-grounded in literature, data unavailability for some of the SDGs in some countries presented a limitation to the study, and future efforts should focus on collecting data for the other SDGs in order to permit a wider application.

Water and nutrition are linked in multiple ways, but few of these interlinkages are well understood. What is, for example, the exact relationship between water pollution and health or between water resource management and nutrition? Even less is known about the interactions across these various linkages. The importance of better understanding these connections has been highlighted as we pursue the United Nations Sustainable Development Goals (SDGs), which challenge mankind to meet both water security as well as food and nutrition security goals, while also improving water-based ecosystems. It has become increasingly clear that progress toward these goals can only be achieved if measures in the food and nutrition space (SDG 2) do not constrain progress on water (SDG 6) and if measures undertaken to support targets under one of these SGDs also support the outcomes of the other. This paper provides an overview of waternutrition linkages as reflected in the SDGs, and it identifies key gaps in these linkages and suggests a way forward to support the achievement of both water and nutrition goals and targets.

Climate change is a complex and cross-cutting problem that needs an integrated and transformative systems approach to respond to the challenge. Current sectoral approaches to climate change adaptation initiatives often create imbalances and retard sustainable development. Regional and international literature on climate change adaptation opportunities and challenges applicable to southern Africa from a water-energy-food (WEF) nexus perspective was reviewed. Specifically, this review highlights climate change impacts on water, energy, and food resources in southern Africa, while exploring mitigation and adaptation opportunities. The review further recommends strategies to develop cross-sectoral sustainable measures aimed at building resilient communities. Regional WEF nexus related institutions and legal frameworks were also reviewed to relate the WEF nexus to policy. Southern Africa is witnessing an increased frequency and intensity in climate change-associated extreme weather events, causing water, food, and energy insecurity. A projected reduction of 20% in annual rainfall by 2080 in southern Africa will only increase the regional socio-economic challenges. This is exacerbating regional resource scarcities and vulnerabilities. It will also have direct and indirect impacts on nutrition, human well-being, and health. Reduced agricultural production, lack of access to clean water, sanitation, and clean, sustainable energy are the major areas of concern. The region is already experiencing an upsurge of vector borne diseases (malaria and dengue fever), and water and food-borne diseases (cholera and diarrhoea). What is clear is that climate change impacts are cross-sectoral and multidimensional, and therefore require cross-sectoral mitigation and adaptation approaches. In this regard, a wellcoordinated and integrated WEF nexus approach offers opportunities to build resilient systems, harmonise interventions, and mitigate trade-offs and hence improve sustainability. This would be achieved through greater resource mobilisation and coordination, policy convergence across sectors, and targeting nexus points in the landscape. The WEF nexus approach has potential to increase the resilience of marginalised communities in southern Africa by contributing towards attaining the Sustainable Development Goals (SDGs 1, 2, 3, 6, 7, and 13).

Globally, more than 60% of the human population live without safely managed sanitation services or even lack access to basic sanitation facilities. In addition, most of the wastewater produced in the world is discharged without proper treatment. Integrated approaches are needed to address these issues and curb the resulting adverse impacts on public health and the environment, and associated societal economic losses. The UN 2030 SDG Agenda provides an important framework towards more sustainable sanitation development, in terms of both safe sanitation access and wastewater management. Innovative solutions that treat and enable productive safe use of water, and recovery of nutrients and organic matter from wastes resources are booming. Some examples of trends are decentralized solutions, separation of waste flows, low/or no-flushing toilets, and converting faecal sludge to energy. These alternative technologies show huge potential to address many development challenges, contributing to multiple SDGs, but achieving upscaling has proved to be a major challenge. A paradigm shift to ‘treatment for reuse’ instead of ‘treatment for disposal’ is already taking place in the wastewater sector. Nevertheless, a better understanding of driving forces and enabling environment, new organizational models based on more service-oriented sanitation provision, and highlighting potential multiple societal benefits to attract investments from new sectors, are identified areas that need further attention.

Bonn, Germany: United Nations Convention to Combat Desertification 25p. (Global Land Outlook Working Paper) More... | Fulltext (570 MB)
With current rates of land degradation reaching ten to twelve million ha per year, there is an urgent need to scale up and out successful, profitable and resource-efficient sustainable land management practices to maintain the health and resilience of the land that humans depend on. As much as 500 million out of two billion ha of degraded land, mainly in developing countries, have restoration potential, offering an immediate target for restoration and rehabilitation initiatives.1 In the past, piecemeal approaches to achieving sustainable land management have had limited impact. To achieve the ambitious goals of alleviating poverty, securing food and water supplies, and protecting the natural resource base, we need to recognize the inter-connectedness of the factors driving land degradation, so that solutions can be taken to scale, transforming management practices for millions of land users. An analysis of the critical barriers and incentives to achieve scaling up suggests that the most appropriate options should be selected through the involvement of stakeholders at all levels, from local to national and international. New incentives for land managers as well as the public and private sectors are required to achieve a land degradation-neutral world.

The rapidly growing population in Uzbekistan has put massive pressure on limited water resources, resulting in frequent water shortages. Irrigation is by far the major water use. Improving irrigation water use through the institutional change of establishing water consumer associations (WCAs) has been identified as a way to increase agricultural production and meet the food demand in the area. However, most WCAs are not fully able to organize collective action or generate sufficient funds to carry out their responsibilities. This study investigated the water-resource-related challenges faced by WCAs and local farmers in Kashkadarya Province in Uzbekistan, using semi-structured expert interviews and focus group discussions. The resulting data were analyzed using qualitative analysis software (Atlas.ti). The results indicated that outdated infrastructure, poor governance, and farmers’ non-payment of irrigation service fees hamper sustainable water management. Greater trust and communication within the WCAs would make an important contribution to effective collective action and to the long-term sustainability of local associations.

This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project. Based on a combination of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, previous irrigated area mapping exercises carried out by DAFF and three-field ground truthing (GT) surveys, a total of 1.6 million hectares (Mha) of cropland were identified, with 262,000 ha actually irrigated in the 2015 winter season. The study also found that only 29% of all land equipped with center pivots was actually irrigated.

This Research Report chronicles the evolution of thinking on water productivity in the research agenda of IWMI and in the broader irrigation literature over the past 20 years. It describes the origins of the concept and the methodological developments, its operationalization through applied research, and some lessons learned over the two decades of research. This report further highlights how a focus on agricultural water productivity has brought greater attention to critical water scarcity issues, and the role of agricultural water management in supporting broader development objectives such as increasing agricultural production, reducing agricultural water use, raising farm-level incomes, and alleviating poverty and inequity. Yet, reliance on a single-factor productivity metric, such as agricultural water productivity defined as “crop per drop,” in multi-factor and multi-output production processes can mask the complexity of agricultural systems as well as the trade-offs required to achieve desired outcomes. The findings from this retrospective underscore the limitations of single-factor productivity metrics while also highlighting opportunities to support more comprehensive approaches to address water scarcity concerns and, ultimately, achieve the broader development objectives.

Environmental flows (EF) are an important component of Goal 6 (the ‘water goal’) of the Sustainable Development Goals (SDGs). Yet, many countries still do not have well-defined criteria on how to define EF. In this study, we bring together the International Water Management Institute’s (IWMI’s) expertise and previous research in this area to develop a new methodology to quantify EF at a global scale. EF are developed for grids (0.1 degree spatial resolution) for different levels of health (defined as environmental management classes [EMCs]) of river sections. Additionally, EF have been separated into surface water and groundwater components, which also helps in developing sustainable groundwater abstraction (SGWA) limits. An online tool has been developed to calculate EF and SGWA in any area of interest.

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.

Wetlands can only be well managed if their spatial location and extent are accurately documented, which presents a problem as wetland type and morphology are highly variable. Current efforts to delineate wetland extent are varied, resulting in a host of inconsistent and incomparable inventories. This study, done in the Witbank Dam Catchment in Mpumalanga Province of South Africa, explores a remote-sensing technique to delineate wetland extent and assesses the seasonal variations of the inundated area. The objective was to monitor the spatio-temporal changes of wetlands over time through remote sensing and GIS for effective wetland management. Multispectral satellite images, together with a digital elevation model (DEM), were used to delineate wetland extent. The seasonal variations of the inundated area were assessed through an analysis of monthly water indices derived from the normalised difference water index (NDWI). Landsat images and DEM were used to delineate wetland extent and MODIS images were used to assess seasonal variation of the inundated area. A time-series trend analysis on the delineated wetlands shows a declining tendency from 2000 to 2015, which could worsen in the coming few years if no remedial action is taken. Wetland area declined by 19% in the study area over the period under review. An analysis of NDWI indices on the wetland area showed that wetland inundated area is highly variable, exhibiting an increasing variability over time. An overlay of wetland area on cultivated land showed that 21% of the wetland area is subjected to cultivation which is a major contributing factor to wetland degradation.

Groundwater is integral to water security. It is the largest store of unfrozen freshwater on earth, and it serves almost half of the global population for basic water needs. In addition, it contributes more than 40% of the irrigation water globally. Groundwater also secures critical ecosystems and ecosystem services, on which people and the environment depend. This paper gives an overview of the significance of groundwater and the critical interlinkages in the WaterFoodEnergyClimateEnvironment nexus. It also discusses how opportunities for bringing in groundwater as part of the solutions to water security at various levels are often missed out. Examples are given of how research can contribute to moving forward to ensure that groundwater plays a stronger role in achieving the SDGs. Realizing that sustainable groundwater development, use and management hinges on conscious and pro-active governance, the presentation gives an highlight of the upcoming book on Advances in Groundwater Governance. Finally, some recent developments in terms of developing global platforms and initiative to work across disciplines, sectors and levels and geographic boundaries to address groundwater management challenges are presented, including GRIPP, the Groundwater Solutions Initiative for Policy and Practice and the Working Group on Groundwater Management under the Sustainable Water Future Program. These initiatives are emerging with strong buy-in from stakeholders at various levels, from local to global.

The water, energy, and food resources share a lot in common; they have strong interdependencies and are inadvertently affected by action in any one of them. Therefore, the nexus approach (integrated policies related to water, energy, and food) is required in the face of growing concerns over the future availability and sustainability of these resources. The nexus approach can help achieve at least some of the “Sustainable Development Goals (SDGs)” (e.g., SDG 2, 6, 7, 12, 13, 15). This chapter discusses trends in availability and consumption of the three key resources (i.e., water, energy, and food) and interactions between them, and finally provides some reasons why the nexus approach can help achieve social and economic development goals.

The Southern African Development Community’s (SADC) water and energy sectors are under increasing pressure due to population growth and agricultural and industrial development. Climate change is also negatively impacting on the region’s water and energy resources. As the majority of SADC’s population lives in poverty, regional development and integration are underpinned by water and energy security as the watercourses in the region are transboundary in nature. This paper reviews the region’s water and energy resources and recommends policies based on the waterenergy nexus approach. This is achieved by reviewing literature on water and energy resources as well as policy issues. Water resources governance provides a strong case to create a waterenergy nexus platform to support regional planning and integration as SADC countries share similar climatic and hydrological conditions. However, there has been a gap between water and energy sector planning in terms of policy alignment and technical convergence. These challenges hinder national policies on delivering economic and social development goals, as well as constraining the regional goal of greater integration. Regional objectives on sustainable energy and access to clean water for all can only be achieved through the recognition of the waterenergy nexus, championed in an integrated and sustainable manner. A coordinated regional waterenergy nexus approach stimulates economic growth, alleviates poverty and reduces high unemployment rates. The shared nature of water and energy resources requires far more transboundary waterenergy nexus studies to be done in the context of regional integration and policy formulation.

We analyse the threats of global environmental change, as they relate to food security. First, we review three discourses: (i) ‘sustainable intensification’, or the increase of food supplies without compromising food producing inputs, such as soils and water; (ii) the ‘nexus’ that seeks to understand links across food, energy, environment and water systems; and (iii) ‘resilience thinking’ that focuses on how to ensure the critical capacities of food, energy and water systems are maintained in the presence of uncertainties and threats. Second, we build on these discourses to present the causal, risks and options assessment for decision-making process to improve decisionmaking in the presence of risks. The process provides a structured, but flexible, approach that moves from problem diagnosis to better risk-based decision-making and outcomes by responding to causal risks within and across food, energy, environment and water systems.

This paper reviews the institutional reforms taken place in minor irrigation systems in Sri Lanka by contrasting those observed during pre-colonial and colonial periods with those after the independence. Formal or informal institutions have governed the operation and performance of the minor irrigation systems with continuous change of authority. While the earlier reforms focused on the irrigation sector with quicker benefits and lower political risks, recent reforms have covered macro institutions, where the benefits are gradual with high political risks. In ancient irrigation system management, decision making and implementation were taken by communities themselves under the feudal system of “Rajakariya” ensuring sustainability and maintaining village ecosystem. With the abolishing of “Rajakariya” system after the arrival of British rulers, the authority was shifted from the community to the government along with the trend of irrigation system management towards centralization and bureaucracy. After independence, though the minor irrigation system management was the responsibility of beneficiary farmers, the authority of the systems was continuously changed between different government agencies. Now, minor irrigation systems are governed by the Department of Agrarian Development and/ or Provincial councils towards sustainability goals while emphasizing the different stakeholder involvement through enforcement of formal and informal rules and procedures. The government continues the commitment to reform because it provides evidence for the political and economic stability, tactical benefits, timely consideration of stakeholders’ perception and information towards the required change.

Agricultural ecosystems and their services: the vanguard of sustainability?Current Opinion in Environmental Sustainability, 23:92-99. [DOI] More...
Sustainable Development Goals offer an opportunity to improve human well-being while conserving natural resources. Ecosystem services highlight human well-being benefits ecosystems, including agricultural ecosystems, provides. Whereas agricultural systems produce the majority of our food, they drive significant environmental degradation. This tension between development and environmental conservation objectives is not an immutable outcome as agricultural systems are simultaneously dependents, and providers of ecosystem services. Recognizing this duality allows integration of environmental and development objectives and leverages agricultural ecosystem services for achieving sustainability targets. We propose a framework to operationalize ecosystem services and resilience-based interventions in agricultural landscapes and call for renewed efforts to apply resilience-based approaches to landscape management challenges and for refocusing ecosystem service research on human well-being outcomes.

The paper investigates the current practices of the green economy, and challenges and opportunities in the Limpopo Province of South Africa. The paper is based on a baseline study designed to gather data from key informants in Limpopo provincial, district and local municipalities. Twenty-three key informants in the province were interviewed. Primary data collected from key informants was supplemented by secondary data from document reviews. Descriptive statistics were used to analyse data on the current practices of green economy, and challenges and opportunities in the province. Findings from the study suggest that there is generally significant awareness of the green economy concept across the provincial district and local municipalities in Limpopo Province. However, there are gaps in terms of information gathering, storage and sharing on green economy activities in the district municipalities, provincial and national departments. The main barriers constraining the implementation of green economy initiatives in the municipalities include lack of information; shortage of workers with full knowledge on green economy; shortage of training programmes on green economy; and costs of implementation. The main recommendations from this research include the need to improve awareness of green economy activities across all levels in the province, especially with communities’ need for evidence-based research to demonstrate the potential of green economy activities that can contribute to job creation and poverty reduction; and training of officials on how the green economy can contribute to addressing developmental challenges such as service delivery, job creation, local economic development and poverty reduction.

Water cooperation has received prominent focus in the post-2015 United Nations Sustainable Development Goals (SDGs). While proposals for measuring water cooperation appear to be converging toward a small set of indicators, the degree to which these proposed indicators draw on past work is unclear. This paper mines relevant past work to generate guidance for monitoring the proposed SDG target related to transboundary water cooperation. Potential measures of water cooperation were identified, filtered and applied in three countries (Botswana, South Africa and Zimbabwe). Six indicators were ultimately determined as being suitable for measuring water cooperation. As the SDG process turns its focus to the selection of indicators, the indicators proposed in this paper may merit consideration.

We explore processes that enable effective policies and practices for managing the links between water, energy, and food. Three case studies are assessed at different scales in the Mekong River basin, Sri Lanka and Zimbabwe. We find that there are considerable opportunities for improving outcomes for sustainable development by finding solutions that accommodate multiple objectives in the nexus. These include making data more publicly available, commissioning independent experts to advise on contested issues, engaging under-represented stakeholders in decision-making, sharing benefits, exploring different perspectives in forums where alternative development options can be tested and engaging decision-makers at different scales.

Ethiopia’s economy and majority of the people’s livelihoods are dependent on agriculture. To develop the socioeconomy of Ethiopia and eradicate poverty, the policy and interventions should focus on agriculture as an entry point. In line with this, the government, bilateral and multilateral donors, NGOs and various institutions share the concepts and priorities identified in the “Plan for Accelerated and Sustained Development to End Poverty (PASDEP).” There are key challenges that need to be strongly addressed on transforming agriculture by overcoming a multitude of problems including biophysical and water management issues to help achieve the targets of PASDEP and sustainable socioeconomic growth in Ethiopia. This particular paper aimed at addressing the water management challenges that Ethiopia has faced in the past and is facing today, and to stimulate ideas on how to manage water resources to meet the growing needs for agricultural products, to help reduce poverty and food insecurity, and to show how water can be used as an important entry point to transform its socio-economy and contribute to sustainable development and the environment. The issues discussed will focus on innovations, policies and technologies that enable better investment and management decisions in water use, particularly focusing on agriculture and irrigation but also briefly looking into other water-related subsectors such as hydropower, water supply, watershed, drought and flood management as well as other biophysical aspects. It has also been attempted to make the paper suitable for decision-makers rather than scientists, in order to raise useful ideas for dialogue and further discussions, studies and researches. The paper, therefore, does not claim exhaustiveness. The target audiences of this paper are the people who make the investment and management decisions in water and water management for agriculture, and other subsectors - agricultural producers, water managers, investors, policymakers and civil society. The paper has benefited from the review of key policy and strategy documents of Ethiopia, outputs of various outcomes of research, civil society meetings and workshops, data and information available in government institutions, and global knowledge. The key major issues that are discussed in the paper include the following: Socioeconomic development challenges of Ethiopia, viewed from a water resources perspective., The water resources endowment, development extent, potentials and economic/socioeconomic development linkages., Water-related innovations and agriculture., Water-related interventions in various agro-ecologies., Policy and strategy actions needed. This paper should also be viewed with other components such as river basin growth pole/corridor concept, institutional reform and research capacity building. It focuses on analyzing key problems and associated interventions, and can be applicable in the contexts of the current situation and the future possib

The aim of the research project is to lift Afghanistan out of the identified knowledge gap on its water resources and therefore enable Afghanistan to remove her barrier to sustainable water resource development and management in the Amu Darya basin. At the same time it is anticipated to provide transparency of the potential impact of water resource development plans as well as of on-going projects to downstream riparian states as well as the donor community which so far seems to take an administrative rather than a resource boundary approach.The duration of the project is anticipated to be 3 years. Because of its international position IWMI Central Asia will take the lead in data generation and analysis and will collaborate with research and implementing agencies in Afghanistan, Tajikistan, Turkmenistan and Uzbekistan.

A framework is built, wherein hydrological/water quality model is used to measure watershed sustainability. For this framework, watershed sustainability has been defined and quantified by defining social, environmental and biodiversity indicators. By providing weightage to these indicators, a “River Basin Sustainability Index” is built. The watershed sustainability is then calculated based on the concepts of reliability, resilience and vulnerability. The framework is then applied to a case study, where, based on watershed management principles, four land use scenarios are created in GIS. The Soil and Water Assessment Tool (SWAT) is used as a hydrology/water quality model. Based on the results the land uses are ranked for sustainability and policy implications have been discussed. This results show that landuse (both type and location) impact watershed sustainability. The existing land use is weak in environmental sustainability. Also, riparian zones play a critical role in watershed sustainability, although beyond certain width their contribution is not significant.

Water managers in large cities in developing countries experience great difficulties in providing proper water supply and sanitation services in a context of rapidly growing population with changing water use patterns, structural lack of capacity and resources. There is a need for in-depth city-wise water assessments of fast growing large cities in developing countries to help gain insight into the implications of urban water and sanitation development scenarios on urban water demand, wastewater disposal and downstream water use. The generation of reliable data sets and modeling results for a selection of cities will help understand the present and future impact that water use has on water resources and flows that cross the urban-rural divide. Also, an easy-to use model can support decision making at the local urban water planning and policy level. This paper describes ongoing research on the urban water system in three fast growing cities in the South. The application of integrated urban water management in developing countries is needed for the sustainable management of water resources within the city and basin.

When ecosystems services fail, human health suffers - and for no ecosystem is this link more direct than for wetlands. One third of the world’s population lacks sufficient clean water for drinking, personal hygiene and cooking, and about two million people die annually from waterborne diarrhoeal disease. Even when water is available in abundance, ecosystem disruptions can carry a heavy disease burden: over-irrigation results in standing water in which disease-carrying mosquitoes breed, and water used by industry often allows toxins to enter the human food chain. Altered hydrologies and vegetation structures can lead to hardship, global environmental change, and, most recently, a host of new, ‘emerging’ infectious disease epidemics. Poor wetland management leads to a deterioration of both wetland ecosystem health and human health. It is only in the last couple of decades that we have come to appreciate the strength of the fundamental relationship between wetland ecosystem health and human health, and therefore the importance of developing environmental management strategies that support the maintenance of both wetland ecosystem health and human health concurrently. However, the concept of what constitutes a healthy wetland is not straightforward. Whilst the slogan ‘Healthy Wetlands, Healthy People’ may resonate with many people, wetland health is still largely a subjective concept. It is also one that is heavily influenced by our political ecologies; there are many complexities and uncertainties when considering healthy people and healthy wetlands. These complexities and the inter-related scientific issues are explored in this paper - what is a healthy wetland and how does a healthy wetland affect human health?

At IWMI, researching underlying economic and social trends helps us understand why people migrate. They also explain the impact of remittances and loss of agricultural labor, as well as consequences of migration on gender roles and food and water security. For instance, communities with higher levels of income inequality, or relative deprivation, may experience greater levels of out-migration compared to consistently low-income communities. In addition, migration changes intra-household gender-labor composition, which can change the access of smallholders to water resources, affecting the functioning of community-based institutions and consequently household and local food security. IWMI also focuses on circular economy, a strategy to recover and reuse waste, to boost food security and understand how interventions can encourage refugee and host communities to retain scarce resources.

Urban & rural transformation
As agricultural opportunities fluctuate in rural areas, migration, particularly to urban areas, is an adaptation technique to secure incomes and alternative livelihoods. Income generated by migrants is often sent back to family as remittances to support communities at home. At IWMI, we assess linkages between rural and urban areas, as well as the role of agricultural knowledge systems and food and water security. We recognize there are complex push and pull factors such as individual aspirations, economic opportunity, social norms, climate variability and government policies which drive migration and affect rural communities, particularly youth. Our work follows a ‘positive migration’ philosophy, framing migration as an adaptation technique and socio-economic choice (in many cases) rather than a problem to be solved, and focuses on establishing safer, more regular migration by supporting changes to migration governance in sending regions.

Covid-19 disruption & adaptation
Covid-19 has caused a rupture in migration logistics and exposed inequities in the migration system, yet drivers of movement remain. Government lockdowns and closed borders due to the pandemic curtailed movement for migrants, posing complex problems for migrant hosting and origin countries. There have been significant economic shocks, with a sharp decline in unemployment for migrants and an inability to send money home through remittances to support family. Some migrants face social stigma for returning home without an income, particularly if families relied on loans to support their journeys. Consequences have been severe for informal migrants who lack government protection in their host countries. Migrants, particularly those living in crowded, lower-income neighborhoods, have been experiencing stigmatization related to the spread of Covid-19. We look at the impacts of Covid-19 on migration governance and rural areas across seven countries,development planning in Ghana, migration challenges in Southeast Asia, and community-based disaster management and resilience building in South Africa.

Water, climate change and agrarian stress
Migration, water and climate stress are inextricably linked to rural development. Water stress and climate variability can act as a driver of fragility, intensifying pre-existing political, social, economic and environmental challenges. Initiatives designed to address migration-related challenges must tackle inequalities and the exclusion of women, youth and marginalized groups; governance opportunities to better manage water and natural resources and technology and innovations to help communities escape socio-ecological precarity and thrive despite climate challenges. IWMI intends to build climate resilience by implementing projects which tackle gender-power inequalities in the face of dynamic, economic-social-ecological challenges. Our work brings together affected communities, institutional stakeholders and social actors to manage water in response to climate variability and agrarian stress, striving to address complex physical and social variables.

Gender, intersectionality and social inclusion
It is critical to center gender and intersectional identities when unpacking migration phenomena. Gender as a social construct guides social norms and relations, including the decision-making processes and mechanisms leading to migration. We recognize that the intersections between race, age, class, sex, caste and region shape the migrant experience.
IWMI strives to offer transformative approaches and solutions for women, youth and marginalized groups, regarding them as equal partners in our work rather than passive end-users. For example, within communities that experience male out migration, socio-political systems are restructured to make women, youth and other groups active agents in their own agri-food transformation. Migration patterns contribute to the feminization of agriculture, and women may experience a greater burden of responsibility coupled with an increased ability to access and control resources and policies to build sustainable livelihoods. Acknowledging social complexities helps researchers and communities understand migration trends and address structural power imbalances to build a more equitable world.

Farmer-led irrigation development is about much more than installing a pump in a field. It requires access to financing, labor, energy, and input and output markets, so that investments in irrigation translate into sustainable returns. IWMI uses a systemic approach to understand the farming system as well as the factors in the enabling environment that prevent women, men and youth from engaging in and benefitting equitably from farmer-led irrigation. We partner with farmers and the public and private sectors to test contextually relevant innovation bundles that combine irrigation technology such as solar pumps with financing mechanisms like pay-as-you-own or pay-as-you-go, agricultural inputs and agronomic techniques. We also look at ways to improve on-farm water management and nutrient use efficiency and reduce evapotranspiration through digital advances and agricultural extension. We integrate the scaling of innovation bundles into agricultural value chains to enhance the impacts on farmers’ irrigation investments, incomes and livelihoods.

Gender and social inclusion
The barriers facing women and men in accessing irrigation technologies are not the same. Neither are the benefits. Social, cultural and religious norms influence inter- and intra-household power relations. These, in turn, affect access to resources such as land, credit, information and training. IWMI carries out cross-dimensional analysis of gender and social inclusion in policy, financing, livelihood assets and access, institutional approaches and interventions as well as gender-based technology preferences. For example, we work with farmers, financial institutions and the private sector to address gender-based constraints in credit scoring and enhance women’s purchasing power. But benefitting from farmer-led irrigation does not stop at accessing and adopting technologies; enabling women and resource-poor farmers to participate in input and output markets is equally important to ensure that investments in irrigation result in improved nutrition and economic empowerment. Other ways we enhance gender and social inclusion include tackling agency issues around financial management and literacy, livelihood diversity and social capital as well as access to infrastructure, extension services and market linkages.

Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including Water Accounting+, solar irrigation mapping and internet of things. These are complemented by multi-criteria analysis to evaluate the potential of irrigation expansion, taking into consideration environmental flows. With our private sector partners, we are leveraging converging technologies, such as sensors on solar pumps that capture usage data, to encourage better resource management and governance.

Adaptive scaling and partnerships
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities requires scaling processes to be adaptive. This means diverse actors feed off, adapt to, support, cooperate, compete and interact with each other, forming different multi-actor networks and engaging in collective action to undertake various functions in the scaling ecosystem. IWMI works with farmers and public and private sector partners to co-design and pilot contextually relevant innovation bundles and their scaling pathways or strategies, influence policies and accelerate the transition to scale of innovations with demonstrated early impact.

A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But credit alone is not enough. Financing for irrigation equipment must be embedded in a wider financing ecosystem that bundles credit with inputs and services, market information and access, and technology such as digital payment. In several countries, irrigation equipment suppliers are stepping in to provide financing directly to farmers. In doing so, they increase their own risk. To address this issue, IWMI works with farmers, private companies, finance institutions and development partners such as the World Bank Group to analyze whether credit-scoring tools are inclusive. We also help to identify gaps in the financing ecosystem and de-risk the private sector from testing innovative end-user financing mechanisms that take into account farming system typologies, financial and social capital and crop seasonality.
