Water resources management is a significant challenge for Mexico. The country has in place a system of water resources management that includes both central (federal) and decentralized (basin and local) institutions. Furthermore, water management is imposing a heavy cost to the economy.
The arid northwest and central regions contain 77% of Mexico's population and generate 87% of the gross domestic product (GDP).[1] By contrast, the poorer southern regions have abundant water resources. Surface and groundwater resources are overall overexploited and polluted thus leading to an insufficient water availability to support economic development and environmental sustainability. These challenges are expected to become more complicated as climate change creates more extreme weather and further heat and dry weather in already arid regions.
