This collection reprints the most significant papers and case studies on the prevention and resolution of conflict over water resources. It focuses in particular on the human dynamics that are involved when conflicts over water resources impact on different interest groups, economic sectors and legal or political boundaries. It addresses key issues which arise at both the local and the international level, including amongst others: how do people interact in these situations of conflict?; what methods do they use to find a compromise?; and what institutions do they create - either jointly or unilaterally - to help overcome problems in the future? This interdisciplinary collection should be useful reading for professional water practitioners throughout the world, including engineers, economists, geographers, geologists and political scientists concerned with water disputes and conflict resolution. It should make a significant contribution to the study of water as an essential theme in the increasingly important topic of environmental security.
