The geographic differences of continental water distribution and
availability in Mexico has to be explained by regional, temporal and elevation
conditions as well as in the context of social and economic differences,
and all these variables should be considered for the optimal
management and adequate use of this resource. The highest concentration
of freshwater occurs in the southeastern part of the country, where
population density and demand is low compared to a larger population
density and number of industries and agricultural lands in the central
and northern territories. By water usage, agriculture captures most of
the resource (75.72%), followed by public demand (14.65%), generation
of electricity (5.55%), and industry (4.09%)
