Is Mexico prepared for the next big drought?

A difficult scenario awaits the state of Sonora in coming years because, according to experts, changing climate patterns throughout the planet will cause drying conditions.

Luis Brito Castillo, doctor of ecology at the (CIBNOR), says people living in the northwestern state will have to learn to cope with those conditions, while society will also "have to end daily, noxious habits and raise awareness in children about proper use of drinking water and electricity. "

" Humankind has triggered climate change ... by the excessive use of fuel in all its forms: at factories, in cars, to generate power: . In particular, there is poor preservation of flora coupled with deforestation and soil erosion, which are directly related to the availability and quality of water.

According to the National Institute of Ecology, Deforestation is caused by wildfires or illegal logging, coupled with the poor treatment of pests and diseases.

The state also presents the most serious drought levels, going from strong to very severe. The Environment and Natural Resources Secretariat predicts that dry areas in the state will increase by 30% by 2030.

CIBNOR researchers back to proposal that accepts the coastal and tourist development of Sonora, while rejecting projects that lead to economic gain that benefits only a few. Such a development would build a cutting-edge tourist industry that benefits the state's residents while respecting the new conditions created by climate change.

The state government itself has already begun to address climate change through its Ecology and Sustainable Development Commission, which has created an action plan to reduce greenhouse gas emissions.

Droughts are now projected to last between 20 and 40 years, in contrast to the past when they lasted, at the longest, a decade. Some experts are certain that in the next 35 years, as a result of climate change, Mexico and the world will be facing reduction in the numbers of whales, sharks and tuna, along with other large species.

The National Water Commission, Conagua, says in a report entitled Water Agenda 2030 that the yearly demand for water in Mexico is now 78,400 million cubic meters, of which only 11,500 million is extracted from aquifers that are already overexploited.

The country also produces 6,700 million cubic meters of wastewater, a figure that will increase to 9,200 million cubic meters by 2030. Only 38% of wastewater is currently treated in accordance with regulations. The most polluted river basins are the Lerma, Valley of Mexico and Balsas as a result of untreated wastewater.

States challenged by drinking water and sewage system deficiencies are Baja California, Chiapas, State of Mexico, Jalisco, Puebla and Veracruz.

In the event of a mega-drought, which would be harsher than the one suffered in 2011-2012, cataloged by experts as outstanding due to its length and intensity, harsh blow. Dry conditions proper to northern states would turn them into the most vulnerable to water shortages.

Dr. Brito Castillo's conclusion is that while conditions in northern Mexico are expected, the occurrence of transient weather events like hurricanes will also increase.
