Download or read book Water Harvesting in Sub Saharan Africa written by William Critchley and published by Routledge. This book was released on 2013-01-04 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.

Download or read book Shaping the Future of Water for Agriculture written by and published by World Bank Publications. This book was released on 2005 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural water management is a vital practice in ensuring reduction, and environmental protection. After decades of successfully expanding irrigation and improving productivity, farmers and managers face an emerging crisis in the form of poorly performing irrigation schemes, slow modernization, declining investment, constrained water availability, and environmental degradation. More and better investments in agricultural water are needed. In response, the World Bank, in conjunction with many partner agencies, has compiled a selection of good experiences that can guide practitioners in the design of quality investments in agricultural water. The messages of 'Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management' center around the key challenges to agricultural water management, specifically: - Building policies and incentives - Designing institutional reforms - Investing in irrigation systems improvement and modernization - Investing in groundwater irrigation - Investing in drainage and water quality management - Investing in water management in rainfed agriculture - Investing in agricultural water management in multipurpose operations - Coping with extreme climatic conditions - Assessing the social, economic, and environmental impacts of agricultural water investments 'Shaping the Future of Water for Agriculture' is an important resource for those interested and engaged in development with a focus on agricultural water.

Book excerpt: 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.

Download or read book Water for Food Water for Life written by David Molden and published by Routledge. This book was released on 2013-07-23 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

This book was released on 2011-08-30 with total page 1339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.
Download or read book The Nile Basin written by John Waterbury and published by Yale University Press. This book was released on 2008-10-01 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The supply and management of fresh water for the world’s billions of inhabitants is likely to be one of the most daunting challenges of the coming century. For countries that share river basins with others, questions of how best to use and protect precious water resources always become entangled in complex political, legal, environmental, and economic considerations. This book focuses on the issues that face all international river basins by examining in detail the Nile Basin and the ten countries that lay claim to its waters. John Waterbury applies collective action theory and international relations theory to the challenges of the ten Nile nations. Confronting issues ranging from food security and famine prevention to political stability, these countries have yet to arrive at a comprehensive understanding of how to manage the Nile’s resources. Waterbury proposes a series of steps leading to the formulation of environmentally sound policies and regulations by individual states, the establishment of accords among groups of states, and the critical participation of third-party sources of funding like the World Bank. He concludes that if there is to be a solution to the dilemmas of the Nile Basin countries, it must be based upon contractual understandings, brokered by third-party funders, and based on the national interests of each basin state. “This excellent book makes a significant contribution to the rational discussion of Nile conflicts and should be helpful to many of the other 282 international river basins facing similar problems.”—Peter P. Rogers, Harvard University
