SAN MIGEL TOPILEJO, Mexico, Sep 26 (IPS) – Verónica Molina, an indigenous Comcaac girl, first got here into contact with photo voltaic vitality in 2016, when she travelled to India for coaching on communal photovoltaic amenities. This later enabled her to participate within the set up of the primary photo voltaic techniques and household vegetable gardens in her group, Desemboque del Seri, in northern Mexico.
Afterward, she was invited to the venture Vitality, Water and Meals Safety for Indigenous Peoples in Semi-Arid Coastal Areas of Northern Mexico, sponsored by the governmental Nationwide Council of Humanities, Science and Know-how (Conahcyt), which started in 2022.
“We plant greens, as a result of there are not any different seeds to make use of. They’re for self-consumption. With the panels, we pay much less for vitality, and with the gardens we lower your expenses on greens,” the photo voltaic activist instructed IPS from Desemboque del Seri, some 1,900 kilometres from Mexico Metropolis.
Along with producing their very own electrical energy, the collaborating households harvest quite a lot of greens in Desemboque and neighbouring Punta Chueca, Comcaac territories inhabited by some 1,200 folks on the coast of the state of Sonora, and one in all Mexico’s 69 indigenous peoples, who additionally fish.
Whereas the panels cowl between 25% and 75% of a family’s consumption, every of the greater than 40 household gardens offers between 100 and 200 kilograms of greens for every of the 2 annual harvest seasons.
The area suffers from marginalisation, poverty and illness. In distinction, it receives a day by day photo voltaic irradiation of 5.9 kWh/m2 and an annual rainfall of 200 millilitres, which makes seasonal agriculture tough.
The initiative consists of a hybrid system that mixes photovoltaic era and meals manufacturing, positioned underneath the panels to harness the solar, shade and dew that they seize through the night time, which is in vogue in international locations equivalent to Germany, Brazil and the USA.
This eco-technology continues to be in its infancy in Mexico, and it’s unknown what number of techniques are in operation within the nation. The Mexican Agrovoltaic Community is making ready a census to find out their standing.
In truth, the Strategic Plan on Local weather Change for the Agri-Meals Sector consists of amongst its targets using photo voltaic panels for electrical energy era.
Mitigation
“We realised that that they had well being, financial system, meals, and land points. We appeared for complete options, aligned with the price range. They’ve the ocean or the desert, it is an especially arid place,” Rodolfo Peón instructed IPS from Hermosillo, the capital of Sonora.
“We noticed that agriculture was a substitute for enhance their weight loss plan and supply electrical energy,” added the researcher from the Division of Industrial Engineering on the public College of Sonora, referring to the venture within the Comcáac territory.
That is how the agrovoltaic scheme, the one low-cost resolution for the world, got here on the scene.
Funded by Conahcyt’s Nationwide Strategic Programmes with some 450,000 {dollars}, the venture addresses the parts of vitality, water, meals, well being, biodiversity and territorial defence.
Since 2018, the federal government has been driving, with little success, for inside capability (sovereignty) in meals manufacturing for Mexico’s inhabitants of some 130 million folks.
Mexico presently ranks eleventh on the earth in meals manufacturing. Throughout the first seven months of this 12 months it exported extra agri-foods than in the identical interval final 12 months, though it additionally purchased extra, albeit in an agricultural steadiness with a surplus.
The nation is very weak to the results of the local weather disaster, equivalent to drought, rising temperatures and the unfold of pests.
Because of this, producers of maize, beans, wheat, espresso and different conventional merchandise are already struggling the impacts of phenomena equivalent to this 12 months’s acute water shortages, and can undergo much more detrimental impacts in the long run, with penalties for high quality of life, earnings and the agricultural atmosphere.
Latin America’s second largest financial system has round six million rural manufacturing models, of which 75% are lower than 5 hectares in measurement and solely 6% have greater than 20 hectares, supporting some 20 million folks.
As well as, 79% of electrical energy era is dependent upon fossil fuels, adopted by wind (7%), photovoltaic (4.5%), hydroelectric (4.4%) and nuclear (3.7%). In accordance with the Electrical energy Transition Regulation, the nation ought to generate 35% of its electrical energy from different sources by 2024, however this can be a distant aim.
The administration of outgoing President Andrés Manuel López Obrador, which started in December 2018 and can finish on 1 October, put the brakes on vitality transition in an effort to strengthen the state-owned Federal Electrical energy Fee, which burns fuel for electrical energy era, and Petróleos Mexicanos, thus favouring fossil fuels.
The nation has agrovoltaic potential, with 20 million hectares of land underneath cultivation and greater than 10,000 megawatts of photovoltaic energy, 70% of which is in in depth amenities.
Hybrid experiments
At a peak of 4 metres, six modules of photovoltaic panels seize photo voltaic vitality which, after passing by means of a converter, shall be reworked into electrical energy. Sheltered by them, 24 beds home pumpkin, lettuce and tomato crops, which profit from protecting shade, and rainwater and night time dew caught by the panels.
This takes place within the Sustainable and Academic Agrovoltaic Plot (Pase), positioned in a nook of the Middle for Sensible Educating and Analysis in Animal Manufacturing and Well being of the School of Veterinary Medication and Animal Science of the general public Nationwide Autonomous College of Mexico (UNAM).
The centre is positioned in San Miguel Topilejo, a city within the municipality of Tlalpan, within the south of Mexico Metropolis.
On the facility visited by IPS, on the opposite facet of a mud street, stalled cattle graze whereas the photovoltaic system waits for the overcast skies to open up and bathe them within the solar’s nourishing rays.
On one facet of the plot there are six extra open-air beds to check the outcomes with these protected by the panels.
Throughout an earlier tour of the ability, Aarón Sánchez, an instructional on the Unam’s Institute of Renewable Energies and coordinator of the plot, defined that they’re learning how crops develop underneath a photovoltaic roof that generates electrical energy.
He defined that they analyse their efficiency when there’s a transpiration course of within the decrease a part of the crops themselves, and the modules work at a decrease temperature and better effectivity.
Inaugurated in 2023, the Pase goals to extend the standard and amount of agricultural merchandise, generate inexperienced vitality, scale back water consumption, and socialise new applied sciences amongst farmers.
The plot, which has a rainwater harvesting system with a 145 cubic metre tank to feed the drip irrigation system and temperature and humidity sensors, additionally entails the Mexico Metropolis authorities’s Ministry of Training, Science, Know-how and Innovation.
A world consortium of establishments from the USA, France, Israel, Kenya, Morocco and Mexico can be collaborating.
Again in Sonora, Molina and Peón referred to as for extra help to broaden the techniques.
“We are able to ask for extra help, as a result of some households in the neighborhood haven’t had entry to the agrovoltaic backyard. Hopefully the venture will be continued”, the group photovoltaic skilled mentioned.
Peón believes the outcomes are promising, however a lot stays to be completed.
“We hope that there shall be a federal programme to help indigenous peoples. There needs to be a change within the guidelines of the sport (for folks to generate their very own vitality in better volumes),” he mentioned.
“There must be synergy between the vitality and agricultural sectors, in order that we are able to see large-scale initiatives”, he added.
