As long as there have been communities sharing water, there have been
disputes over how the water has been shared. The Middle East, an enorm
ous dry region stretching from Marrakech to Samarkand, has had some of
the longest experiences of such controversies. Today many of the rive
r basins within the region illustrate the effectiveness and limitation
s of both customary international law and treaty law in resolving such
problems at the interstate level. This article examines the national
communities sharing two highly contested river basins-the Jordan and t
he Nile-in the region as examplars of those successes and failures.(1)
