One of the most salient of contemporary issues in Global Change is the dynamics of water movement across large river basins to the sea, and the politics thereof. Increases in resource demand rise directly with increases in population and the generation of wealth. Significant medium to longterm climate change and altered frequency and severity of extreme events will likely complicate the priority setting and decision-making processes. Conflicts arising from regional inequities in access to and capture of water will be exacerbated in the years ahead, with a growing human population and with the stresses that global changes will impose on water quality and availability. Understanding the subtle relations between the forcing provided by seasonal and interannual variability in climate expressed across an evolving landscape provides important insight into the processes controlling the intrinsic dynamics of meso-scale river basins, while providing important information for basin managers. Case studies of international river basins (Amazon, Zambezi, Mekong, Huang-He) illustrate the importance of the application and extension of information systems based on NASA and NOAA platforms and synthetic models for resolving the science issues pertaining to resource agendas required by emerging initiatives of such entities as the World Bank and Global Environment Facility.
