Sustainable urban water management in the State of Mexico (WWDR2, 2006)
Mexico comprises 31 States and the Federal District (the Capital). The State of Mexico, located in the centre of the nation of Mexico, suffers from severe water shortages due to a very dense population coupled with accelerated growth, especially in the Metropolitan Zone of the Valley of Mexico (which comprises the totality of the Federal District area and 18 municipalities located in the State of Mexico) with approximately 20 million inhabitants. Currently, water is transferred from local and external basins to meet the demands of the Metropolitan Zone. Increasing water demand has led to 100% or more overexploitation of groundwater resources. The effects are striking: groundwater level is declining. Consequently, in some cases the ground has been sinking up to 40 centimetres per year, aquifers have lost their hydrostatic pressure and some springs have dried up. Water and sewer infrastructure has also been damaged due to sinking ground.
The state government is constantly pursuing new mechanisms to slow down urban growth and to promote efficient water use. Federal and state policies are being implemented to promote an integrated approach towards the sustainable utilization of water, forest and land resources. The programmes and projects stemming from these policies strive to increase the participation of local stakeholders, improve infrastructure and enhance legal frameworks.
