For decades now we have wasted and mismanaged the world?s water supplies. Today, 27 countries are short of water, a quarter of the world?s population has no safe water, 46 per cent have no proper sanitation and each year four million children die of water-borne diseases. As most of the world?s major river systems cross several national boundaries, the scope disputes and the threat to international security is becoming more and more real. In The Last Oasis, Sandra Postel examines the economic, ecological and political factors affecting fresh water supply. She confronts the issues of mismanagement and profligacy and analyses and dangers of confrontation, both between nations and between rural and urban users. She also emphasises that the technology and know-how for effective water husbandry does exist. With methods already in use, farmers could cut their demand for water by 40-90 per cent, and cities by one-third, without sacrificing economic output or quality of life. Investing in water efficiency, recycling and conservation help meet rising demands and stave off disaster. But the priority is a common recognition of the gravity of the position, and with that a widespread push for institutions to manage sustainable use of water.

This new three volume series presents a broad and integrated approach to water management, purification, and conservation in arid climates. Volume one includes an introductory chapter on water problems and water resources in arid climates followed by specific chapters covering various aspects of water management. Volumes two and three deal with water purification and water conservation, respectively. Many textbooks on water issues normally deal with only one of these areas. This series covers all three areas with an emphasis on the problems faced by arid regions. The three volume series will appeal to industry specialists in desalination and wastewater treatment, irrigation engineers, graduate and undergraduate students in hydrology, water management and conservation professionals, government personnel involved in water resources development, decision makers, environmentalists, employees of the petrochemical industry, and individuals wishing to specialize in water management, purification and conservation.

This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

This report reviews several decades of global experience in transferring management of government-run irrigation systems to farmer associations or other nongovernmental agencies in an attempt to apply the lessons of success to the African smallholder irrigation context.

High irrigation investment costs together with declining world prices for food and the failures of a number of high profile past irrigation projects are the main reasons for the reluctance of development agencies and governments in sub-Saharan Africa to invest more resources in irrigation. This study aims to systematically establish whether costs of irrigation projects in sub-Saharan Africa are truly high, determine the factors which influence costs and performance of irrigation projects, and recommend cost-reducing and performance-enhancing options to make irrigation investments in the region more attractive. It analyzes 314 irrigation projects implemented from 1967 to 2003 in 50 countries in Africa, Asia, and Latin America funded by the World Bank, African Development Bank and the International Fund for Agricultural Development.

This book provides a comprehensive analysis of the benefits and challenges of intensifying groundwater irrigation in Sub-Saharan Africa (SSA) for improving smallholder agrarian livelihoods. Only about 3% of the groundwater resources of Sub-Saharan Africa are used for irrigated agriculture despite the subcontinent’s relative abundance of groundwater. The majority of the region’s smallholders are highly dependent on seasonal dryland cropping, making them extremely vulnerable to uncertain weather patterns and droughts. Improved irrigation capabilities through sustainable groundwater development could unleash smallholder farming and make it a major driver of economic growth, poverty reduction, climate resilience, and improved food security. So, why is groundwater so underused? Tapping into groundwater requires a major shift in farming practices and it has its own challenges and requirements – smallholder access to land and finance for irrigation infrastructure and equipment, gendered and equitable adoption options. This whole list is framed in terms of what the smallholder farmers need. Hence, this should also be put in this context, supply chains, energy access, resource availability, and institutional support. The chapters in this book present a picture that is not only heterogeneous across the region, but also hold some common denominators. They serve to enrich the discourse and help better understand the barriers along the pathways toward the sustainable and transformative adoption of groundwater irrigation. The scientific information provided herein would be of interest to researchers, practitioners, decision makers and planners with interest in the region. This book was originally published as a Special Issue of Water International journal.

Only 4 percent of arable land in sub-Saharan Africa is irrigated, using just 2 percent of the available water resources. Furthermore, 18 percent of the area equipped for irrigation is not utilized at all and the intensity of use varies between 50 percent and 80 percent. This highlights the huge potential available for intensifying and expanding irrigated area, provided that the investments required can be successfully mobilized. However, it must be noted that if investments in irrigation are to yield satisfactory returns, investments must also be made in a series of related activities. Current global figures for the amount of private investment in irrigation confirm that good returns can indeed be achieved. Prospects for sub-Saharan Africa would be far more favorable if public development assistance, particularly foreign direct investments, did not show declining trends.

Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990
