The status of the National Irrigation Return Flow Research and Development Program is presented. Current research projects and future program development are discussed. The report represents the position of the Environmental Protection Agency (EPA) with regard to the development of effective controls on the quality of irrigation return flows. Program goals and milestones are outlined. A number of potential control measures are discussed. Improvements in the water delivery system, on-the-farm water management, and the water removal system are considered with respect to improving the quality of irrigation return flows and decreasing the degradation of receiving waters. Research and investigations are needed to evaluate the effectiveness of potential control measures. Demonstrations and educational activities will be required to overcome institutional, political, and legal constraints to water management reform.

When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"â€"trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

This book is an outcome from the International Expo 'Water and Sustainable Development' held in Zaragoza (Spain) in 2008. Support from the Spanish Ministry of Environment, Caja Rioja, Government of Aragon, and the World Bank is acknowledged. 'Few resources will play a more important role in shaping our economic future, or face more daunting challenges, than water. This internationally acclaimed team of experts has produced a first-rate volume that is full of intriguing, practical ideas for meeting those challenges in a rich variety of institutional settings.' Tom Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College, USA 'This volume brings together two critical but interrelated dimensions of water challenge, i.e. water pollution, particularly from non-point sources, and water conservation. The editors are well known experts on the subject as are the contributors.' R. Maria Saleth, International Water Management Institute, Sri Lanka and Associate Editor, Water Policy 'The profound contribution of this volume is that it brings together various economic concepts and policy dilemmas regarding water shortages, non-point source pollution, efficiency of water use and irrigation technology. Recommended reading for anyone working in the area of water management.' Henk Folmer, University of Groningen and Wageningen University, The Netherlands As countries face deteriorating water and environmental quality as well as water shortages, pollution control and the efficiency of water use become of paramount importance. Agriculture is one of the main non-point polluters of water bodies and irrigation for agriculture is one of the main consumers of water. While it is very hard to regulate pollution from agriculture, attempts have been made via economic and command and control instruments, and also through investments in technologies and ecosystems recovery. Coping with non-point pollution takes the form of both policy intervention and technology development. Likewise it is recognized that irrigation efficiency varies across countries, influenced by both technology and supporting adoption policies. Countries that lead in irrigation technology and supporting policies have certain traits in common. They face very high scarcity and are pushed to find innovative solutions, both technical and policy related. The recent multibillion investments in irrigation technologies in Spain, and similar proposals in Australia, for example, highlight the potential of irrigation technologies to cope with scarcity and water quality degradation. This book reviews all of the above issues, presents experiences in selected countries, and assesses the degree of success of alternative policies for coping with non-point water pollution and improving irrigation efficiency.
