Emerging regional perspectives on water research and management: An introductory comment

Two noted American geographers specializing in water resource management introduce a series of papers in a Eurasian Geography and Economics symposium on water security and hydro-politics by outlining the diverse regional constructs (e.g., river basins, nation-states, global regions) that have been utilized in water management efforts in the past. The authors suggest that the problemshed concept may represent the real context of contemporary regional water struggles and management, and may appear in such forms as water security regions, water wars between neighboring states, water-energy-food regions, and virtual water regions and footprints. They conclude by reviewing the ways in which the three symposium papers that follow contribute to a deeper understanding of transboundary water use and conflict management.
