It is often assumed that upstream land use practices have important impacts on water resources and affect the downstream users at a watershed scale, Payments by downstream users to upstream users for "environmental services" such as good water quality, less sediments or more regular water flow are widely discussed. However, much controversy exists about the direction and magnitude of such impacts, how they influence the relationships between upstream and down-stream users, and which mechanisms allow for a sharing of resulting benefits and costs by all resource users in a watershed context. To address these issues, the FAO Land and Water Development Division organized the electronic workshop "Land-Water Linkages in Rural Watersheds" from 18 September to 27 October 2000. The present publication contains the proceedings of the workshop and two papers that set the stage for the workshop discussions. The complete workshop documentation, including discussion archive, background papers, and case studies, is included on the CD-ROM that accompanies the document.

This Athens Workshop helped to illustrate what needs to be done to manage water sustainably in agriculture, in particular through reviewing the experiences in OECD countries.

Environmental issues have become increasingly prominent in local struggles, national debates, and international policies. In response, scholars are paying more attention to conventional politics and to more broadly defined relations of power and difference in the interactions between human groups and their biophysical environments. Such issues are at the heart of the relatively new interdisciplinary field of political ecology, forged at the intersection of political economy and cultural ecology. This volume provides a toolkit of vital concepts and a set of research models and analytic frameworks for researchers at all levels. The two opening chapters trace rich traditions of thought and practice that inform current approaches to political ecology. They point to the entangled relationship between humans, politics, economies, and environments at the dawn of the twenty-first century and address challenges that scholars face in navigating the blurring boundaries among relevant fields of enquiry. The twelve case studies that follow demonstrate ways that culture and politics serve to mediate human-environmental relationships in specific ecological and geographical contexts. Taken together, they describe uses of and conflicts over resources including land, water, soil, trees, biodiversity, money, knowledge, and information; they exemplify wide-ranging ecological settings including deserts, coasts, rainforests, high mountains, and modern cities; and they explore sites located around the world, from Canada to Tonga and cyberspace.

Bringing contributions by a variety of authors together in one volume is part of an attempt to show that hydropolitics is a growing discipline in its own right. The prevailing definition of hydropolitics is widened to include the elements of scale and range. This is illustrated through a focus on theoretical and legal issues, case studies from Southern Africa and a proposed research agenda. The book is an important addition to the literature on hydropolitics.

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

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.
