The purpose of this Guide is to provide an overview of the major considerations and steps to be followed in organizing new irrigation farmers’ organizations or Irrigation Water Users’ Associations (IWUAs). The Guide should support developing or strengthening a specialized formal IWUA for implementing a program aimed at creating or improving a collectively managed irrigation scheme. The Guide is focused on programs involving construction of new irrigation schemes; rehabilitation, modernization or revitalization of existing irrigation schemes; or supporting farmers wishing to improve the performance of their irrigation scheme. While based on extensive research and evidence, the intended audience for this Guide is the set of practitioners responsible for planning and implementing communal irrigation programs. This may include managers of publicly or externally supported projects, government agricultural and irrigation officials, private investments and nongovernmental organizations.; The Guide draws on over 50 years of experience organizing farmers to participate in the creation, improvement and management of both farmer-managed and government-managed irrigation schemes. The major lesson learned is that investing in the “software” component – training and institutional development – of irrigation is critical for success. If the IWUA is weak or ineffective, the scheme will fail to achieve its potential, no matter how good the hardware is.; The Guide seeks to avoid imposing a specific organizational design for what an institution should look like and do, but suggests a process organized around six ‘steps’ to be followed, more or less in sequence. Using these steps creatively as a guideline, not as a recipe to be followed precisely, will increase the likelihood that irrigation investments achieve the desired project goals.

This Atlas summarizes recent advances in interdisciplinary approaches and research to address the different components of West African urban food systems, including urban and peri-urban agriculture. It thereby draws on the results of several major collaborative research projects and stakeholder consultations conducted in West Africa over the past two decades, and in particular on the UrbanFoodPlus project in Ghana and Burkina Faso (www.urbanfoodplus.org). The publication targets with its innovative design a broad range of stakeholders.

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 water–nutrition 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.

Current patterns of agricultural expansion and intensification are bringing unprecedented environmental externalities, including impacts on water quality. While water pollution is slowly starting to receive the attention it deserves, the contribution of agriculture to this problem has not yet received sufficient consideration. We need a much better understanding of the causes and effects of agricultural water pollution as well as effective means to prevent and remedy the problem. In the existing literature, information on water pollution from agriculture is highly dispersed. This repost is a comprehensive review and covers different agricultural sectors (including crops, livestock and aquaculture), and examines the drivers of water pollution in these sectors as well as the resulting pressures and changes in water bodies, the associated impacts on human health and the environment, and the responses needed to prevent pollution and mitigate its risks.

This report outlines a participatory approach for mapping actors along value chains. The methodology provides novel ideas on how to combine value chain analysis with participatory statistics and visual network research approaches, to generate valuable insights about complex value chains together with local stakeholders in a cost effective way. A framework is introduced, which provides a canvas for mapping actors onto different analytical dimensions relevant in value chain analysis. After outlining some of the conceptual foundations and the methodological approach, a sequence of steps for mapping actors and their relationships is described. The experience from a case study is used to illustrate the steps involved. The case study is on fodder value chains in the Sahelian agro-ecological zone of Burkina Faso, but the mapping approach can be adapted to a range of contexts.

This paper provides a brief synthesis of research conducted on gender in irrigation, and the tools and frameworks used in the past to promote improvement for women in on-farm agricultural water management. It then presents results from the pilot of the Gender in Irrigation Learning and Improvement Tool (GILIT) in locations in Malawi and Uzbekistan in 2015. Through the results of the tool, the paper looks at benefit sharing between men and women farmers: (i) access to irrigation scheme resources (including information, for example, in the design phase; land, water and other inputs); (ii) participation in scheme management; and (iii) access to scheme benefits, including access to market information, packaging and payments. The indicators for the tool were modelled after principles reflected in existing gender policies and strategies, and intended to improve performance at field level in line with national and regional goals. The paper concludes with informal and formal constraints to gender-equitable outcomes from irrigation investments identified during the pilot, and suggests how the tool can be used by various development actors to improve the benefits for women from investments in agricultural water management.

In most developing countries wastewater treatment systems have very low coverage or function poorly, resulting in large-scale water pollution and the use of poor-quality water for crop irrigation, especially in the vicinity of urban centres. This can pose significant risks to public health, particularly where crops are eaten raw.; Wastewater Irrigation and Health approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings. The book therefore complements other books on the topic of wastewater which focus on high-end treatment options and the use of treated wastewater.; This book moves the debate forward by covering also the common reality of untreated wastewater, greywater and excreta use. It presents the state-of-the-art on quantitative risk assessment and low-cost options for health risk reduction, from treatment to on-farm and off-farm measures, in support of the multiple barrier approach of the 2006 guidelines for safe wastewater irrigation published by the World Health Organization. The 38 authors and co-authors are international key experts in the field of wastewater irrigation representing a mix of agronomists, engineers, social scientists and public health experts from Africa, Asia, Europe, North America and Australia. The chapters highlight experiences across the developing world with reference to various case studies from sub-Saharan Africa, Asia, Mexico and the Middle East. The book also addresses options for resource recovery and wastewater governance, thus clearly establishes a connection between agriculture, health and sanitation, which is often the missing link in the current discussion on ‘making wastewater an asset’.

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

This report and the Side Event at CSD 16, May 5–16, 2008, are following up reports that have been prepared for two previous CSD meetings, “Water – More Nutrition per Drop” (2004*) and “Let it Reign: The New Water Paradigm for Global Food Security” (2005**). The topics addressed in the previous reports, and also in this report, are the links between water, food and development, which are high on the agenda for Swedish international development collaboration. This report highlights the magnitude of losses and wastage in the food chain, i.e. from field to fork. It is shown that a reduction of losses and wastage would save water and facilitate the achievement of multiple development objectives.

The quot;Ruhuna Basinsquot; defined for this case study encompass three of the main rivers that flow through ancient Ruhuna, including the longest and most important river in the region, Walawe. The Ruhuna basins are important in the broader Sri Lankan context, the basin being the location of a major hydropower plant, irrigation schemes that make a significant contribution to national food production, and important nature reserves. However, even before the proposed development begins to be implemented, the basins are experiencing major water resources problems, clearly demonstrated by the recent drought that led to reduction of water supplies to agriculture, insufficient domestic water supply, and which contributed to nationwide power cuts upto 8 hours a day. These challenging issues motivated the Government of Sri Lanka to select the cluster of three important rivers, Walawe, Menik and Kirindi, and the smaller basins confined by them as the area for the case study for the World Water Assessment Program.

The WaterDome was organized by the African Water Task Force, AWTF, with IWMI as its implementing agency.

The core of this study involved an examination and analysis of certain key features of the traditional small tank cascade systems: a) the location and design of the systems in the past b) the hydro-system which considers the overall hydrological balance and groundwater conditions c) maintenance and tank use d) tank management and integration with local farming systems

This publication reports on a study of the increase in river salinity and the implemented control programs in five major irrigated basins in the arid zone. The study is limited to salinity.

Groundwater offers us few but precious opportunities for alleviating the misery of the poor; but it poses many—and daunting—challenges of preserving the resource itself. A big part of the answer is massive initiatives to augment groundwater recharge in regions suffering depletion; but, in the ultimate analysis, these cannot work without appropriate demand-side interventions. The water vision of a world that future generations will inherit will have to be the one in which groundwater plays its full developmental, productive and environmental role but in a sustainable manner; and the framework of action to realize this vision will mean eschewing the current free-for-all in groundwater appropriation and use, and promoting a more responsible management of this precious resource that is easy to deplete or ruin—through depletion, salinization and pollution

Water is being transferred out of agriculture to meet the growing demand in other areas, often without an agreement of or compensation to farmers with irrigated land and water rights. Furthermore, there is a failure to recognize that irrigation systems supply water not only for the main fields, but also for domestic uses, home gardens, trees and other permanent vegetation, and livestock. Other productive uses include fishing, harvesting of aquatic plants and animals, and a variety of other enterprises such as brick making. In addition, irrigation systems can have a positive or negative effect on wildlife habitats. Thus, the withdrawal of water affects the rural household, rural economy, and the environment in a number of ways. This paper argues that to ensure efficient, equitable, and sustainable water use, to reduce poverty and improve the well-being of the community, irrigation and water resources policies need to take into account all uses and users of water within the irrigation system. The multiple uses of water in the Kirindi Oya irrigation system are examined in this paper. An interdisciplinary group of scientists have investigated a number of areas including water accounting, water quality, household water use, the valuing of water for alternative uses, and the complementarities, competition, and conflicts among uses and users.

This paper aims to describe the state of theart of both water harvesting (WH) andsupplemental irrigation (SI) techniques in the temperate and sub-tropical dry lands, especiallyin the countries of WANA that are characterized by a Mediterranean-type climate. In addition,three case studies of water harvesting are presented (see annex). These were selected from the case studies presented at the FAO Expert Consultation Cairo (1994). By sharing with us the success and the failure of these endeavors, the authors of the case studies illustrate many of the points that are made in the text. They also illustrate how difficult it is to successfully introduce new technologies to farmers, who at the outset are not usually familiar with the intended purpose of the changes. Also, this paper emphasises that it is difficult to assess the potential for adoption without more studies to assess the risks and economic returns of the alternative techniques and practices.

The world is facing severe and growing challenges in maintaining water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these challenges facing water resources management; and modeling at this scale can provide essential information for policy makers in their decisions on allocation of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

The System-Wide Initiative on Water Management (SWIM) has defined its central theme and objective as “enhancing the productivity of water and agriculture in an environment of growing scarcity and competition.” One program area of SWIM, namely SWIM 7, has the aim of improving the utilization of water resources from the catchment perspective. This paper has been prepared as part of the process of planning research that is to be undertaken by SWIM 7. The paper includes a historical review of research that has involved the use of catchment experiments and a discussion on hydrological modeling techniques. Options for improving water utilization at the catchment and farm scales are identified, and recommendations are made for research that might be undertaken by SWIM 7. The case is argued for interdisciplinary catchment studies that involve the participation of local communities and other stakeholders.

Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p; roductivity in rice-based systems.

This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and water developments at the catchment scale.
