Disagreements over the management and allocation of transboundary freshwater resources have become increasingly prominent in international relations. Serious diplomatic tensions surround management of the Jordan, Mekong, Nile, Rio Grande, Silala, Syr Darya and Amu Darya, and Tigris and Euphrates rivers, to name just the most prominent examples among the world’s more than three hundred shared watercourses. Nor is there any reason to think tensions will subside in the future. Whether disagreements over shared freshwater resources will continue to be resolved peacefully will depend, in part, on the viability, durability, and flexibility of international law to prevent and resolve such disputes. This symposium examines the role and relevance of international water law for peacefully resolving disputes over transboundary freshwater resources. The articles in this compilation provide an impressive breadth of approaches, from close examination of contemporary disputes over transboundary freshwater resources to the interpretation and application of specific IWL norms and principles. The articles also feature the perspectives of scholars from Africa, Asia, Europe, and North America.
