The Southern African Development Community (SADC) and its Member States are making renewed efforts to revive agriculture in the region. Given that much of it is water-stressed, appropriate and sustainable land and water management practices are vital to achieving this objective. Recognising this, SADC's Land and Water Management Applied Research and Training Programme has convened two scientific symposiums. Held in Lilongwe, Malawi, in February 2006, the inaugural symposium brought together R&D practitioners from 10 participating SADC countries to deliberate on land and water management for sustainable agriculture, and discuss how the most recent research and development advances in land and water management might be made more relevant to policy-makers as well as the region's small-scale farmers. The edited contributions to the first symposium appear in this volume. The second symposium was held in Gaborone, Botswana, in February 2007, and brought together regional experts to discuss opportunities for improving water use and water use efficiency in agriculture in semi-arid and arid areas. The edited contributions to the second symposium appear in a companion volume entitled Land and Water Management in Southern Africa: Towards Better Water Use in Agriculture in Semi-Arid and Arid Areas (AISA 2008). It is hoped that these two volumes will help to disseminate regional expertise on land and water management to a wider audience, thus helping policy-makers and others to strengthen the agricultural sector in the region, and, in so doing, improve its food security and the wellbeing of its people.

Annotation Agriculture is the major user of water in most countries. it also faces the enormous challenge of producing almost 50% more food by 2030 and doubling production by 2050. This will probably be achieved with less water, mainly because of growing pressures from urbanisation, industrialisation and climate change. In this context, it will be important in future for farmers to receive the right signals to increase water use efficiency and improve agricultural water management, while preserving aquatic ecosystems. This report focuses on policy makers to recognise the complexity and diversity of water resource management in agriculture And The wide range of issues at stake. And it gives them the tools to do so, offering a wealth of information on recent trends And The outlook for water resource use in agriculture, including the impacts of climate change. it examines the policy experiences of OECD countries in managing their water resources for agriculture, with focus on: The extent to which countries subsidise the supply of water to farmers; flood and drought risk policies; and institutional organisation and governance as it relates to water And The agricultural sector. The report offers recommendations on what countries should be doing and why.

Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).

In a worldwide context of ever-growing competition for water and land, climate change, droughts and man-made water scarcity, and less-participatory water governance, agriculture faces the great challenge of producing enough food for a continually increasing population. In this line, this book provides a broad overview of innovation issues in the complex water–agriculture–food nexus, thus also relative to their interconnections and dependences. Issues refer to different spatial scales, from the field or the farm to the irrigation system or the river basin. Multidisciplinary approaches are used when analyzing the relationships between water, agriculture, and food security. The covered issues are quite diverse and include: innovation in crop evapotranspiration, crop coefficients and modeling; updates in research relative to crop water use and saving; irrigation scheduling and systems design; simulation models to support water and agricultural decisions; issues to cope with water scarcity and climate change; advances in water resource quality and sustainable uses; new tools for mapping and use of remote sensing information; and fostering a participative and inclusive governance of water for food security and population welfare. This book brings together a variety of contributions by leading international experts, professionals, and scholars in those diverse fields. It represents a major synthesis and state-of-the-art on various subjects, thus providing a valuable and updated resource for all researchers, professionals, policymakers, and post-graduate students interested in the complex world of the water–agriculture–food nexus.

In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses and, as a sector, irrigated agriculture will have to increase the efficiency and productivity of its water use. This is particularly true for manually operated irrigation systems managed by government agencies, which provide water for a large number of users on small landholdings and represent 60% of the total irrigated area worldwide. Drawing on the author's 30 years of experience in some 28 countries, this book offers knowledge of the management of irrigation and drainage systems, including traditional technical areas of systems operation and maintenance, and expanding managerial, institutional and organizational aspects. Chapters provide guidelines to improve management, operation and maintenance processes, which move management thinking out of traditional public-sector mindsets to a more customer-focused, performance-oriented service delivery. As a practical guide to improve efficiency and productivity in irrigated agriculture, this book will be essential reading for irrigation managers and technicians as well as students and policy makers in water management, agriculture and sustainable development.
