Water resources that are shared across boundaries by different states or countries are referred to as “transboundary” or “international” water resources. Worldwide, there are about 263 international basins that are shared by two or more countries, with 40 percent of the world population living on these international basins (Giordano and Wolf, 2003). This is an increase from the 214 basins that were identified in 1978, due to better mapping technology and newly emerging nations. For example, the collapse of the Soviet Union in 1991 created 15 new independent nations and simultaneously created new transboundary water resources.
