"According to the 2008 Stockholm Water Prize winner, Tony Allan, the Middle East basically “ran out of water” in the 1970s and today largely depends on water from outside the region being traded into the region, primarily in the form of its food imports. Nevertheless, about 87% of the region’s freshwater is allocated to agriculture. Continued water scarcity will affect the region’s social and economic potential, increase land vulnerability to salinization and desertification, and raise the risk for political conflict around the limited water available. Still, arid zones are no less prone to violent behavior than states sharing water in water humid zones."
