Based on an international symposium addressing a key issue in global development, this reference includes both the latest methodologies for and practical examples of effective management of transboundary water resources. Its multidisciplinary approach combines hydrology and environmental science with economic and political approaches, in line with new UNESCO and EU recommendations, which have been formulated and implemented with the active involvement of all three editors. By providing a theoretical framework as well as abundant case studies from southern Europe, Africa, Asia and South America, this handbook provides hydrologists, geologists, engineers and decision-makers with all the knowledge they need for their daily work.
