Book Description
Water Productivity and Food Security: Global Trends and Regional Patterns, Volume Three reviews the need for water productivity improvements in agriculture, addressing three distinct questions pertaining to agricultural water productivity improvement in developing countries, including what are the regions where water is a limiting factor for raising agricultural outputs and water productivity improvements, what are the technological measures in irrigation that can raise agricultural water productivity and result in water saving at various scales, and what opportunities exist in the developing economies of South Asia and Africa for raising water productivity and improving water economy at basin scale. This book provides a framework to characterize river basins based on water availability, water supplies, water uses and water demands to ascertain the need and measures available for improving crop water productivity that would be effective at various scales, i.e., plant-level, plot-level, irrigation system level and basin level. This is an essential reference for anyone interested in water management and agriculture. Presents clear explanations of the physical and technical measures that can be adopted to improve productivity of water in agricultural production under different basin conditions Offers physical strategies for improving water productivity in agriculture in different agroecological regions, along with the institutional and policy measures that affect them Includes methodologies for assessing the food security challenges of individual nations using empirical analysis and global datasets

Book Description
First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Book Description
The report uses a nutritional water productivity (NWP) framework to interpret the relationship between nutrition and water in the context of water challenges. It argues that higher yields – of both staple and nutritious crops – are possible, even in water-stressed areas. This will require an agricultural transformation that ensures that efforts to enhance water productivity are linked to the promotion of healthy diets. Increasing water productivity and stabilizing yields at realistic levels will also be crucial to increasing the resilience of farmers. Better coordination and timing of water and other inputs, notably fertilizers and improved seeds, is likely to enhance productivity and to reduce the threats of a further encroachment of agriculture into other ecosystems. A diversified production system is required for food security, nutrition and poverty alleviation. There is an opportunity to provide strategic support for crops and other farm produce with high economic and nutritional value. A range of crops and other produce can be included in farming systems ranging from rainfed to irrigated agriculture. For the farmers to be stimulated and able to capitalize on the increasing need and demand for such produce, the development of markets, and associated investments in cold storage, roads/transport and food procurement programmes that prioritize nutritious produce will be key.

Book Description
The role of irrigation in gearing agriculture development towards a broader economic growth is undeniable. Accordingly, irrigation is growing into key operational strategy for governments and their agencies to increase agricultural productivity, thus combatting food insecurity and boosting overall growth. While agriculture absorbs rural workforce, generates income and increases food security, it has become the most important driver in freshwater exploitation. The rapid expansion of water demand leads to the generalized phenomena of imbalance between water supply and water demand. This increasing pressure on water resources urges enhancing Water Use Efficiency. Enhancing Water Use Efficiency requires actions at all levels, from agricultural practitioners to scheme managers, and up to the policy-makers. The objective of this Field Guide is to show practical measures to improve Water Use Efficiency in small-scale agriculture based on case studies from Burkina Faso, Morocco and Uganda. The Book not only presents applicable Water Use Efficiency measures, but also guide the readers through their real-term implementation. While the Guide provides complete set of instructions to improve Water Use Efficiency in order to reach optimal irrigation practices, the successful outcome still depends on the farmers’ willingness to embrace and adopt the recommended measures. The Guide holds in evidence that farmers are often constrained by available resources to improve their practices in terms of budget, inputs or labour. In order to take these issues into account, the recommendations are limited on practical measures, which can be followed by farmers without requiring additional resources.

Book Description
This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Book Description
This paper provides an overview of innovative options for developing and using water for food production in sub-Saharan Africa (SSA) in light of the growing scarcity and competition for water resources. These options include rainwater harvesting, selective development of wetlands for agriculture, exploitation of shallow groundwater, and recycling urban waste. The options are largely based on low-cost individualized technologies, which lend themselves to private-sector promotion.Water-demand management approaches are also discussed.

Book Description
In developing countries, further progress of irrigation is essential for increasing food security and farmers’ income. However, developing small-scale schemes remains a challenge due to multiple factors that must be taken into consideration, such as diversity of small-scale schemes, a large number of water users, social disharmony over the water use, varying water demands of multi-cropping systems, heterogeneity of equipment over the scheme. Furthermore, on-farm irrigation development has a major role in enhancing Agricultural Water Management (AWM). The previous development methods considered the improvement of single-factor productivity, but agriculture is undergoing a global shift from the single objective of outputs (such as yield or net income) to multiple objectives of increasing outputs while conserving natural resources. Many pathways towards enhancement of Water Productivity (WP) are directly related to improving overall farm agronomic management (irrigation, fertilization, plant density, plant protection, etc.), while external measures must be applied to ensure sustainability of introduced good practices (lack of input markets, scarce knowledge, poor infrastructures, water regulations, etc.). Thus introducing irrigation practices to farmers must undergo a step-wise process to ensure that costs do not outweigh achievable benefits, and both institutional and technical environment are capable to sustain results. This is the case in smallholders’ schemes, where farmers are poorly resourced. In order to address these issues, the current policy guide presents a combined methodology, which involves practical experiences drawn from FAO work in the three countries as well as researchers’ results to line up a set of feasible measures to improving WP.

Book Description
The report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. It has been prepared by a team of FAO staff and consultants in the framework of the project "Coping with water scarcity - the role of agriculture", and has been discussed at an Expert Consultation meeting organized in FAO, Rome, during the period 14-16 December 2009 on the same subject. It was subsequently edited and revised, taking account of discussions in the Expert Consultation and materials presented to the meeting. The purpose of the Expert Consultation was to assist FAO to better design its water scarcity programme. In particular, the experts were requested to provide recommendations on the range of technical and policy options and associated principles that FAO should promote as part of an agricultural response to water scarcity in member countries. The document offers views on the conceptual framework on which FAO's water scarcity programme should be based, proposes a set of definitions associated with the concept of water scarcity, and indicates the main principles on which FAO should base its action in support to its member countries. At the meeting, experts were requested to review the draft document and provide feedback and recommendations for its finalization. Issues that were addressed in discussions included: 3⁄4 Water scarcity: agreement on key definitions. 3⁄4 The conceptualisation of water scarcity in ways that are meaningful for policy development and decision-making. 3⁄4 The quantification of water scarcity. . 3⁄4 Policy and technical response options available to ensure food security in conditions of water scarcity. . 3⁄4 Criteria and principles that should be used to establish priorities for action in response to water scarcity in agriculture and ensure effective and efficient water scarcity coping strategies.
