According to the United Nations (UN), transboundary waters—the aquifers and lake and river basins shared by two or more countries—account for an estimated 60 percent of global freshwater flow and are home to more than 40 percent of the world’s population. Depleted and degraded transboundary water supplies have the potential to cause social unrest and spark conflict among countries.
A main objective of the U.S. Government Global Water Strategy (GWS) is to promote cooperation on shared—or transboundary—waters and to diffuse potential conflicts over water between countries. A key development result in USAID’s Water and Development Plan (appended to the GWS) is to improve the management of water resources in water-stressed basins that are the source of important drinking water supplies.
Under the GWS and the USAID Water and Development Plan, the U.S. Government works to prevent transboundary water conflict and to improve the management of water resources in shared river basins by promoting the development of agreements and other approaches that support the cooperative management of shared water resources that are critical to the health and livelihoods of millions of people, and to the economies of many nations.
