Mexico, between lack and abundance of water

Abstract

Mexico is in the global strip of deserts. However, the annual volume of renewable water that’s been derived from the water cycle is enough to not suffer water stress despite the recorded population growth. Water management in Mexico has been integrated and directed to cities and urban areas to have water at all cost. The aim of this study is to demonstrate that water management in Mexico leads to water resources scarcity. Data concerning the annual renewable water per capita by federal entity, and the volume treated by municipal and industrial discharges at the national level were used. The method applied was the comparison between annual renewable water per person per federal entity and water policy on the supply and treatment of discharges. It stresses the drought in eight federal entities (the most populated and major contributors to domestic production). It is concluded that all municipal and industrial discharges must be sanitized, reused and used to recover the bodies of surface water and groundwater in each of the states of Mexico.
