The development of societies is shaped to a large extent by their resources base, notably water resources. Access to and control of water depend primarily on the available technology and engineering feats, such as river-diversion structures, canals, dams and dikes. As growing human pressure on water resources brings actual water use closer to potential ceilings, supply-augmentation options get scarcer, and societies, therefore, usually respond by adopting conservation measures and by reallocating water towards more beneficial uses.

This book contains 11 papers which cover a range of vital topics in the areas of water, agriculture, food security and ecosystems - the entire spectrum of developing and managing water in agriculture, from fully irrigated to fully rainfed lands. They are about people and society, why they decide to adopt certain practices and not others and, in particular, how water management can help poor people. They are about ecosystems - how agriculture affects ecosystems, the goods and services ecosystems provide for food security and how water can be managed to meet both food and environmental security objectives. This is the eighth book in the series.

International experts discuss how to restore degraded ecosystems and bring water resources to a level at which they can be sustained naturally. Examines the relationships between the various water-related activities of man and formulates acceptable tactics for the integrated development of river basins.

This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.

This is a fully revised and expanded second edition of Malcolm Newson's acclaimed book. Exploring in greater depth the meaning of sustainability in river basin development this new edition: * highlights the rapid evolution of practical concepts since the Rio Earth Summit * features new illustrations and case studies from Australia, South Africa and Israel * makes the ecosystem model more explicit throughout * strengthens coverage of the linkages between land and water management.

Fresh water is one of man's most vital needs. The distribution of water within river basins has a direct bearing on the organization of water resources development to meet this ever-expanding need. River basins, despite their very great diversity in other respects, have one physical characteristic in common: each is a more or less self-contained unit within whose bounds all the surface and part or all of the ground waters form an interconnected, interdependent system. This inter dependence has such far-reaching implications - for pollution and flood control, apportionment of supply, relations between upstream and downstream riparians, to mention only a few examples - that the river basin has become almost universally accepted (within the past 20 or 30 years at least) as the unit of optimal water resources de velopment. Professor Teclaff's work (which was originally submitted to the New York University School of Law as a doctoral dissertation) is the first fully developed response to the important resolution passed by the International Law Association at its New York meeting in I958 recognizing the legal nature of the international river basin. His study quite properly, therefore, poses the question whether the adoption of the river basin unit is a temporary phenomenon, reflecting the current stage of technology and of administrative, economic, and legal thought on water resources development, or whether the de terminative influence of the river basin's physical unity which has always operated in the past will continue to operate in the future.
