What causes water scarcity in Mexico?
Mexico City is in a state of apparent water scarcity because the aquifer it depends on for most of its supply has been substantially depleted. The aquifer beneath the Conservation Zone provides 60 to 70% of the water consumed in Mexico City, but urban water demand exceeds natural availability (SEDEMA n.d.).
What caused Mexico City’s water crisis?
Currently, more than half the water for the central city comes from its aquifer.

What is Mexico’s water supply?
In 2006, 63% of the Mexican water was extracted from surface water, such as rivers or lakes. The remaining 37% came from aquifers. Due to the strong growth of population and internal migration towards arid and semi-arid regions, many water resources in North and Central Mexico became overexploited.
Why is the water crisis important?
The water crisis is a health crisis. Nearly 1 million people die each year from water, sanitation and hygiene-related diseases which could be reduced with access to safe water or sanitation. … Access to safe water and sanitation contributes to improved health and helps prevent the spread of infectious disease.
