MEXICO CITY, Feb 07 (IPS) – The Mexican authorities is prioritizing the development and modernization of mega water initiatives, with out contemplating their impacts and long-term viability, in line with plenty of specialists and activists.
Dams, reservoirs, canals and aqueducts are a part of the brand new infrastructure aimed toward making certain water provide in areas dealing with shortages, however with out addressing underlying issues corresponding to waste, leaks, air pollution and the affect of the local weather disaster, like droughts.
One of many flagship initiatives is Agua Saludable para la Laguna (ASL), which can serve 5 municipalities within the northern state of Coahuila and 4 within the neighboring area of Durango, benefiting 1.6 million folks.
Gerardo Jiménez, a member of the non-governmental Encuentro Ciudadano Lagunero – an umbrella group made up of 12 organizations of individuals from native communities – stated the ASL initiative launched in 2020 neglects the structural causes of the water disaster, water air pollution and the overexploitation of water sources.
“It focuses on results, shortages and air pollution. It’s designed for a 25-year interval and is predicated on a weak supply. There may be unlawful water extraction and contraband. It doesn’t present various options,” he informed IPS from town of Torreón.
5 of the eight aquifers within the space that present water are overexploited. The Principal-Región Lagunera is an important, supplying 4 cities.
The reservoir turns into cyclically poor, as its annual extraction exceeds its recharge. As well as, the water comprises arsenic above the bounds established by Mexican rules and the World Well being Group (WHO).
ASL consists of the development of a water remedy plant, with a capability of 6.34 cubic meters (m3) per second, a diversion channel and an aqueduct to move 200 million m3 per yr from the Nazas River.
At a price of 485 million {dollars}, the mission is a part of a community of recent water infrastructure promoted by the Nationwide Water Fee (Conagua), Mexico’s water regulatory company, a number of of that are being challenged by social organizations and communities, in some instances via the courts.
The mission additionally features a diversion dam, a pumping plant, storage tanks and distribution branches.
It’s going to begin operations in 2023 and also will harness runoff from the Francisco Zarco reservoir, popularly generally known as Las Tórtolas, and the Lázaro Cárdenas reservoir, generally known as El Palmito.
These reservoirs may cut back their water provide as a result of drought that has affected the world in recent times. The shortage of rain is plaguing half of Coahuila, a scenario set to worsen within the coming months with the arrival of the dry season.
Each dams are nearly overflowing at current, however that degree ought to change when the dry season begins.
Conagua’s finances has recovered from earlier years, from 1.4 billion {dollars} in 2017 to 1.6 billion {dollars} in 2022, concentrated primarily in works to stop floods, attributable to their excessive human and financial prices.
Mexico, a rustic of practically 129 million folks, is very weak to the consequences of the local weather emergency, corresponding to droughts, intense storms, floods, and rising temperatures and sea ranges. Whereas the south and southeast have water in extra, folks within the heart to the north face water shortages.
This Latin American nation has a excessive danger of water stress, in line with the Aqueduct water danger atlas of the Aqueduct Alliance, a coalition of governments, corporations and foundations. Actually, Mexico is the second most water-stressed nation within the Americas, solely behind Chile.
Standard strategy
One other key mission is the Libertad Dam, whose development started in 2020 and is scheduled to be accomplished in 2023, with 132 million {dollars} in financing. Designed to make the most of runoff from the Potosí River, the reservoir will present 1.5 m3/s to satisfy demand in 24 of the 51 municipalities within the northeastern state of Nuevo León, serving 4.8 million folks.
Aldo Ramírez, a researcher on the personal Instituto Tecnológico y de Estudios Superiores de Monterrey, stated massive infrastructure and environmentally pleasant works ought to coexist, as they make totally different contributions, based mostly on a imaginative and prescient of city improvement with an enough hydrological focus.
“Each approaches have their benefits in sure niches,” he informed IPS from Monterrey, the state capital. “Once we take into consideration water administration in cities, a few years in the past the main target was on eradicating the water as rapidly as potential in order that it would not trigger issues. Inexperienced infrastructure may also help so much, it has nice environmental worth, in water administration and aquifer recharge.”
Like different areas of the nation, Monterrey and its outlying neighborhoods, made up of 13 municipalities and inhabited by greater than 5 million folks, is dependent upon the availability of water from the El Cuchillo, Rodrigo Gómez or La Boca and Cerro Prieto dams. The primary holds half of its capability, whereas the opposite two barely retailer any water, in line with Conagua information.
By means of a presidential decree printed in November, President Andrés Manuel López Obrador categorised initiatives that he considers to be of public curiosity and of nationwide safety as excessive precedence and/or strategic for nationwide improvement.
Amongst them are hydraulic and water initiatives, which can obtain provisional specific permits, in a measure questioned by environmental organizations as a result of violation of affect analysis procedures.
ASL, for instance, nonetheless faces a problem filed by the Encuentro Ciudadano Lagunero, whereas 5 others have been withdrawn after agreeing with the federal government to assessment the mission. But when this settlement shouldn’t be revered, the specter of authorized motion stays.
An increasing number of water
Northwest Mexico faces an identical scenario to the opposite areas in disaster and the federal government is constructing two reservoirs and a canal, and upgrading an aqueduct.
Within the state of Sinaloa, development of the Santa María dam on the Baluarte River is transferring forward and it also needs to be accomplished in 2023, to irrigate 24,250 hectares in two municipalities. As well as, it is going to generate 30 megawatts (MW) of electrical energy, with an funding of virtually one billion {dollars}.
The Picachos dam can also be present process modernization, with the set up of generators to generate 15 MW of electrical energy and the irrigation of twenty-two,500 hectares. With a storage capability of 580 million m3, it holds 322 million m3 and can value about 136 million {dollars}.
To the south, within the state of Nayarit, the 58-kilometer-long Centenario Canal, with a capability of 60 m3/s, is being constructed to irrigate 43,105 hectares in 4 municipalities. With an funding of 437 million {dollars}, it is going to serve some 7,500 farmers with water from the El Jileño and Aguamilpa reservoirs, provided by the Santiago River.
As well as, the federal government agreed with opponents of the El Zapotillo dam, within the western state of Jalisco, to go away the dam at a top of 80 meters and function at 50 p.c capability, in order to not flood three cities, to ensure that the mission, price some 340 million {dollars} and with a capability of 411 million m3, to begin working.
However the development of recent dams has ecological repercussions, such because the modification of the panorama, the era of methane and the displacement of individuals, as evidenced by a number of current scientific research.
Within the northern metropolis of Tijuana, on the border with america, the federal government is upgrading the Río Colorado-Tijuana aqueduct, which transfers water from the Colorado River, shared by each international locations, to satisfy city and agricultural demand within the space, at a price of 47 million {dollars}.
Jiménez, of the Encuentro Ciudadano Lagunero, requires the regulation of the extraction of water from the Lázaro Cárdenas reservoir on the Nazas River, in addition to from the wells, a extra exact extraction measurement system, a struggle towards unlawful concession trafficking and the upkeep of the city water distribution community.
“An pressing measure should be taken in order that within the medium time period extraction equals the extent of concessions and in the long run extraction equals recharge. We’re speaking about modifying agricultural manufacturing circumstances and being extra environment friendly in using water,” he stated.
In his opinion, “this case anticipates recurring crises. If it’s not addressed, it is going to worsen, and it’s not vital to succeed in that disaster.”
However, within the midst of this advanced situation, he warned of the shortage of political choice to vary the nation’s water coverage. “The human proper to water shouldn’t be being fulfilled right here,” he stated.
Ramirez the researcher highlighted measures underway, corresponding to stress administration to cut back leaks, the assessment of wells assigned to trade, the reuse of handled wastewater and demand administration.
“We have to make extra environment friendly use of water. We nonetheless have a margin of consumption, however we have to give you extra environmentally pleasant options. We’re heading in the direction of a water disaster,” he stated.
