Monterey, NL. One of the determining factors in water scarcity in New Lionis climate change. Between 2001 to 2004 and in 2009 the temperature dropped because there was good precipitation, in the last 13 years, the average temperature increased 1.7 degrees centigrade per year, this means that the entity was ahead of the average temperature goals established in the paris pact of 1.5% by 2100.
This was commented by the state Environment Secretary, Alfonso Martínez Muñoz, at a press conference.
On the other hand, the consumption of drinking water in the Metropolitan Area of Monterrey has been increasing; between 2002 and 2015 it was an average of 2% per year, after that year consumption increased by more than 4% per year, “if we add it up, the increase will be approximately 24%, however, the availability of water was reduced due to factors weather,” he explained.
On the one hand, the demand in the metropolitan area was 13.2 cubic meters per second, and supply was limited. However, it was not considered for the future offer, since there is less availability in the dams due to greater evaporation. For example, in El Cuchillo more water is lost by evaporation than by consumption, the official pointed out.
Higher demand and lower supply lead to more fires. “This must be in water management, in the future there will be more hot days, we must adapt consumption to this new reality,” stressed Martínez Muñoz.
He explained that, when there is a forest fire, the soil is lost and the rains are not able to infiltrate the subsoil to recover the water table. What is also happening is that between leaks and water theft, there is up to 30% loss of the vital liquid.
The governor Samuel Garcia Sepulvedaasked the secretary for a diagnosis, and to make calculations he resorted to data from 72 meteorological bases of the National Water Commission (Conagua), where cycles of more and less precipitation are observed. In 2009, Hurricane Álex left rainfall well above average, but in the last 13 years it has rained below average, “that stresses the surface and underground sources, however it does not impact the water table.
Proposals for actions
Alfonso Martinez He cited the example of California, which has a serious drought problem, but nevertheless has a powerful government structure that analyzes air quality, the environmental aspect, and natural resources, and has involved the population in joint water management, as well face the crisis and fires.
On the other hand, in Nuevo León the increase of water with more efficient forms has not been stopped, as well as reducing the current demand.
He deepened that to avoid the depletion of underground sources, new sources are sought, for example, water from Las Lajas is incorporated in the citrus zone, where treated water can be brought for agricultural issues, depending on the quality.
He also proposed promoting the capture of rainwater, as is the case in berlinwhere they have a catchment tank, and water is taken from there for the parks.
On the other hand, since there is no regulation in Nuevo León that prevents overuse of water resources, “we are creating some guidelines on the use of water, to have better levels of water efficiency and savings that have to be implemented together with Water Services and Drainage of Monterrey and the Secretary of Government.
