This report focuses on the challenges and opportunities facing Asia—a continent with intensively utilized groundwater and surface water resources. The transboundary basins show signs of resilience, but also of vulnerability. In most instances it is politics and the lack of institutional agreements that play a major role in causing these vulnerabilities. At the regional and sub-regional level, there are entities, often supported by the international community, working to develop, manage, and share the multiple-use potential of shared water resources.
