ABSTRACT
Water is one of Mexico's most critical natural resources. From the early domestication of plants to the rise of the great civilizations, the control of water for agriculture has been a source of power, conflict, and cooperation. Mexico is blessed with water resources, but water is unequally distributed in the country. For example, the northern third of the country has only 3 percent of the hydraulic resources (Restrepo 1995, 10). Long dry seasons in other regions of the country compound the historical significance of water.
