[1] Mexico City's hydrological paradox is that it gets more than enough rain to, in theory, keep the 21 million people who live in and around it adequately supplied with water.
To keep hydrated during the drier months, Mexico City imports water from other regions but mainly just pumps from underground, which causes land subsidence, which makes flooding worse.
Of the 82 irrigation districts present, 42 are in a state of slow deterioration,[3]: 624 exacerbating an inefficient usage of water.
Mexico is also heavily dependent on underground aquifers, as it continues to draw water from these sources to supply almost 70% of its needs.
[10] Repair projects requiring M70 million have since been shelved, contributing to the standstill in efforts to solve Mexico's water scarcity problem.
