A new technology that has arrived in rural villages in El Salvador makes it possible for small farming families to generate biogas with their feces and use it for cooking – something that at first sounded to them like science fiction and also a bit smelly.

In the countryside, composting latrines, which separate urine from feces to produce organic fertilizer, are very popular. But can they really produce gas for cooking?

“It seemed incredible to me,” Marisol Menjívar told IPS as she explained how her biodigester, which is part of a system that includes a toilet and a stove, was installed in the backyard of her house in the village of El Corozal, near Suchitoto, a municipality in the central Salvadoran department of Cuscatlán.”When the first ones were installed here, I was excited to see that they had stoves hooked up, and I asked if I could have one too.” — Marisol Menjívar

“When the first ones were installed here, I was excited to see that they had stoves hooked up, and I asked if I could have one too,” added Marisol, 48. Hers was installed in March.

El Corozal, population 200, is one of eight rural settlements that make up the Laura López Rural Water and Sanitation Association (Arall), a community organization responsible for providing water to 465 local families.

The families in the small villages, who are dedicated to the cultivation of corn and beans, had to flee the region during the country’s 1980-1992 civil war, due to the fighting.

After the armed conflict, they returned to rebuild their lives and work collectively to provide basic services, especially drinking water, as have many other community organizations, in the absence of government coverage.

In this Central American country of 6.7 million inhabitants, 78.4 percent of rural households have access to piped water, while 10.8 percent are supplied by wells and 10.7 percent by other means.

Simple green technology

The biodigester program in rural areas is being promoted by the Salvadoran Water Authority (Asa).

Since November 2022, the government agency has installed around 500 of these systems free of charge in several villages around the country.

The aim is to enable small farmers to produce sustainable energy, biogas at no cost, which boosts their income and living standards, while at the same time improving the environment.

The program provides each family with a kit that includes a biodigester, a biotoilet, and a small one-burner stove.

In El Corozal, five of these kits were installed by Asa in November 2022, to see if people would accept them or not. To date, 21 have been delivered, and there is a waiting list for more.

“With the first ones were set up, the idea was for people to see how they worked, because there was a lot of ignorance and even fear,” Arall’s president, Enrique Menjívar, told IPS.

In El Corozal there are many families with the surname Menjívar, because of the tradition of close relatives putting down roots in the same place.

“Here we’re almost all related,” Enrique added.

The biodigester is a hermetically sealed polyethylene bag, 2.10 meters long, 1.15 meters wide and 1.30 meters high, inside which bacteria decompose feces or other organic materials.

This process generates biogas, clean energy that is used to fuel the stoves.

The toilets are mounted on a one-meter-high cement slab in latrines in the backyard. They are made of porcelain and have a handle on one side that opens and closes the stool inlet hole.

One of the main advantages that family biodigesters have brought to the inhabitants of El Corozal, a small village in the Salvadoran department of Cuscatlán, is that the whole process begins with clean, hygienic toilets, like this one set up in Marleni Menjívar’s backyard, as opposed to the older dry composting latrines, which drew flies and cockroaches.

They also have a small hand pump, similar to the ones used to inflate bicycle tires, and when the handle is pushed, water is pumped from a bucket to flush the waste down the pipe.

The underground pipe carries the biomass by gravity to the biodigester, located about five meters away.

The system can also be fed with organic waste, by means of a tube with a hole at one end, which must be opened and closed.

Once it has been produced, the biogas is piped through a metal tube to the small stove mounted inside the house.

“I don’t even use matches, I just turn the knob and it lights up,” said Marisol, a homemaker and caregiver. Her husband Manuel Menjívar is a subsistence farmer, and they have a young daughter.

In El Corozal, biodigesters have been installed for families of four or five members, and the equipment generates 300 liters of biogas during the night, enough to use for two hours a day, according to the technical specifications of Coenergy, the company that imports and markets the devices.

But there are also kits that are used by two related families who live next to each other and share the equipment, which includes, in addition to the toilet, a larger biodigester and a two-burner stove.

With more sophisticated equipment, electricity could be generated from biogas produced from landfill waste or farm manure, although this is not yet being done in El Salvador.

Saving money while caring for the environment

The families of El Corozal who have the new latrines and stoves are happy with the results.

What they value the most is saving money by cooking with gas produced by themselves, at no cost.

They used to cook on wood-burning stoves, in the case of food that took longer to make, or on liquefied gas stoves, at a cost of 13 dollars per gas cylinder.

Marleni Menjívar, for example, used two cylinders a month, mainly because of the high level of consumption demanded by the family business of making artisanal cheeses, including a very popular local kind of cottage cheese.

Every day she has to cook 23 liters of whey, the liquid left after milk has been curdled. This consumes the biogas produced overnight.

For meals during the day Marleni still uses the liquefied gas stove, but now she only buys one cylinder a month instead of two, a savings of about 13 dollars per month.

“These savings are important for families here in the countryside,” said Marleni, 28, the mother of a four-year-old girl. The rest of her family is made up of her brother and grandfather.

“We also save water,” she added.

The biotoilet requires only 1.2 liters of water per flush, less than conventional toilets.

In addition, the soils are protected from contamination by septic tank latrines, which are widely used in rural areas, but are leaky and unhygienic.

The new technology avoids these problems.

The liquids resulting from the decomposition process flow through an underground pipe into a pit that functions as a filter, with several layers of gravel and sand. This prevents pollution of the soil and aquifers.

Also, as a by-product of the decomposition process, organic liquid fertilizer is produced for use on crops.

Most families in the rural community of El Corozal have benefited from one-burner stoves that run on biogas produced in family biodigesters. Larger two-burner stoves are also shared by two related families, where they cook on a griddle one of the favorite dishes of Salvadorans: pupusas, corn flour tortillas filled with beans, cheese and pork, among other ingredients.

Checking on site: zero stench

Due to a lack of information, people were initially concerned that if the biogas used in the stoves came from the decomposition of the family’s feces, it would probably stink.

And, worst of all, perhaps the food would also smell.

But little by little these doubts and fears faded away as families saw how the first devices worked.

“That was the first thing they asked, if the gas smelled bad, or if what we were cooking smelled bad,” said Marleni, remembering how the neighbors came to her house to check for themselves when she got the latrine and stove installed in December 2022.

“That was because of the little information that was available, but then we found that this was not the case, our doubts were cleared up and we saw there were no odors,” she added.

She said that, like almost everyone in the village, her family used to have a dry composting toilet, but it stank and generated cockroaches and flies.

“All that has been eliminated, the bathrooms are completely hygienic and clean, and we even had them tiled to make them look nicer,” Marleni said.

She remarked that hygiene is important to her, as her little girl can now go to the bathroom by herself, without worrying about cockroaches and flies.

‘Passion Seeds’ Fertilize Brazil’s Semiarid Northeast

ESPERANÇA, Brazil , Jul 14 2023 (IPS)

Zé Pequeno cried when he learned that the heirloom seeds he had inherited from his father were contaminated by the transgenic corn his neighbor had brought from the south. Fortunately, he was able to salvage the native seeds because he had shared them with other neighbors.

Euzébio Cavalcanti recalls this story from one of his colleagues to highlight the importance of “passion seeds” for family farming in Brazil’s semiarid low-rainfall ecoregion which extends over 1.1 million square kilometers, twice the size of France, in the northeastern interior of the country.”These are seeds adapted to the semiarid climate. They can withstand long droughts, without irrigation.” Euzébio Cavalcanti

Saving heirloom seeds is a peasant tradition, but two decades ago the Brazilian Semiarid Articulation (ASA), a network of 3,000 social organizations that emerged in the 1990s, named those who practice it as individual and community guardians of seeds. By September 2021, it had registered 859 banks of native seeds in the region.

Cavalcanti, a 56-year-old farmer with multiple skills such as poet, musician and radio broadcaster, coordinates the network of these banks in the Polo de Borborema, a joint action area of 14 rural workers’ unions and 150 community organizations in central-eastern Paraíba, one of the nine states of the Brazilian Northeast.

“These are seeds adapted to the semiarid climate. They can withstand long droughts, without irrigation, that is why they are so important,” he explained. They also preserve the genetic heritage of many local crop species and family history; they have sentimental value.

“Don’t plant transgenics, don’t erase my history”, is a slogan of the movement that promotes agroecological practices and is opposed to the expansion of genetically modified organisms in local agriculture. “Corn free of transgenics and agrotoxins (agrochemicals)” is the goal of their campaign.

In Paraíba, the name “passion seeds” has been adopted, instead of native or heirloom seeds, since 2003, when the state government announced that it would provide seeds from a specialized company to family farmers.

“If the government offers these seeds, I don’t want them. I have family seeds and I have passion for them,” reacted a farmer in a meeting with the authorities.

“‘Passion seeds’ spread throughout Paraíba. In other states they’re called ‘seeds of resistance’,” Cavalcanti said.

Agroecology is one of the banners of the Polo de Borborema, as it is for ASA in the entire semiarid ecosystem that covers most of the Northeast region and a northern strip of the southeastern state of Minas Gerais.

“Passion seeds,” as heirloom seeds are known locally, ensure better harvests on semiarid lands, free of transgenics or “agricultural poisons,” according to Euzébio Cavalcanti, a small farmer, poet and musician who helped lead the struggle for agrarian reform and cares for the seeds in the highlands of Borborema, in northeastern Brazil.

Learning to coexist with semiarid conditions

This approach arose from a change in the development strategy adopted on the part of local society, especially ASA, since the 1990s. “Coexisting with semiarid conditions” replaced the traditional, failed focus on “fighting the drought”.

Large dams and reservoirs, which only benefit large landowners and do not help the majority of small farmers, gave way to more than 1.2 million tanks for collecting rainwater from household or school rooftops and various ways of storing water for crops and livestock.

It is a process of decolonization of agriculture, education and science, which prioritizes knowledge of the climate and the regional biome, the Caatinga, characterized by low, twisted, drought-resilient vegetation. It also includes the abandonment of monoculture, with the implementation of traditional local horticultural and family farming techniques.

The Northeast, home to 26.9 percent of the national population, or 54.6 million inhabitants according to the 2022 demographic census, concentrates 47.2 percent of the country’s family farmers, according to the 2017 agricultural census. There are 1.84 million small farms worked mainly by family labor.

Brazil’s semiarid region is one of the rainiest in the world for this type of climate, with 200 to 800 millimeters of rain per year on average, although there are drier areas in the process of desertification.

Borborema, the name of a high plateau that obstructs the humidity coming from the sea, making the territory to its west drier, is the scene of various peasant struggles, such as the mobilization for agrarian reform since the 1980s and for small-scale agriculture “without poisons” or agrochemicals, of which the “seeds of passion” are a symbol.

Cavalcanti is a living memory of local history, also as a founder of the local Landless Workers Movement (MST) and an activist in the occupations of unproductive land to create rural settlements, on one of which he gained his own small farm where he grows beans, corn and, vegetables and has two rainwater collection tanks.

Women help drive the expansion of agroecology

Women have played a key role in the drive towards agroecology. The March for Women’s Lives and Agroecology is an annual demonstration that since 2010 has defended family farming and the right to a healthy life.

This year, on Mar. 16, 5,000 women gathered in Montadas, a municipality of 5,800 inhabitants, to block the creation of wind farms that have already caused damage to the health of small farmers by being installed near their homes.

Borborema is “a territory of resistance,” say the women. About 15 years ago, they succeeded in abolishing the cultivation of tobacco.

The president of the Union of Rural Workers of the municipality of Esperança, Alexandre Lira (C) and other leaders pose in front of a poster declaring the union’s current goals: “Agroecological Borborema is no place for a wind farm,” he says about this area in Brazil’s semiarid Northeast region.

When the citrus blackfly arrived, the government tried to combat it with pesticides, but “we resisted; we used natural products and solved the problem for our oranges and lemons,” said Ligoria Felipe dos Santos, a 54-year-old mother of three.

“That is agroecology, which is strengthened in the face of threats. Farmers are aware, they resort to alternative defenses, they know that it is imbalance that leads to pests,” she told IPS.

“Agroecology is a good banner for union activity,” said Lexandre Lira, 42, president of the Rural Workers Union of Esperança, a municipality of 31,000 people in the center of the Polo de Borborema.

It is also a factor in keeping farmers’ children on the farms, because it awakens the interest of young people in agriculture, said Edson Johny da Silva, 27, the union’s youth coordinator.

Pulp, added value

Maria das Graças Vicente, known as Nina, 51, along with her husband Givaldo Firmino dos Santos, 52, is an example of agroecological productivity. On 1.25 hectares of land they produce citrus fruits, passion fruit, acerola (Amazon or Barbados cherry), mango and other fruits, as well as sugar cane, corn, beans and other vegetables.

Grafted fruit tree seedlings are another of the products they use to expand their income, as IPS was shown during a visit to their farm.

Using their own harvest and fruit they buy from neighbors, they make pulp in a small shed separate from their home, with a small machine purchased with the support of the Advisory and Services to Projects in Alternative Agriculture (AS-PTA), a non-governmental organization that supports farmers in Borborema and other parts of Brazil.

“Luckily we have a microclimate in the valley, where it rains more than in the surrounding areas. Everything grows here,” Santos told IPS.

But the couple created three reservoirs to collect rainwater and withstand droughts: a 16,000-liter water tank for household use, another that collects water on the paved ground for irrigation, and a small lagoon dug in the lower part of the farm.

But in 2016 the lagoon dried up, because of the “great drought” that lasted from 2012 to 2017, Vicente said.

The fruit pulp factory has grown in recent years and now has seven small freezers to store fruit and pulp for sale to the town’s stores and restaurants. The couple decided to purchase a cold room with the capacity of 30 freezers.

“I work in the mornings on the land, in the afternoons I make pulp and my husband is in charge of the sales,” she said.

Hiring workers from outside the family to reduce the workload costs too much and “we try to save as much as possible on everything, to sell the pulp at a fair price,” Santos said.

Biodigesters Boost Family Farming in Brazil

Posted on June 24, 2023 by admin

Lucineide Cordeiro loads manure from her two oxen and two calves into the “sertanejo” biodigester that produces biogas for cooking and biofertilizer for her varied crops on the one-hectare agroecological farm she manages on her own in the rural municipality of Afogados da Ingazeira, in the semiarid ecoregion of northeastern Brazil.

AFOGADOS DA INGAZEIRA, Brazil , Jun 24 2023 (IPS)

“The biodigester really gives a huge boost to those who have the courage to do things,” said Maria das Dores Alves da Silva, based on her own experience as a 63-year-old small farmer.

She did not hesitate to accept the offer of Diaconia, a social organization of Protestant churches in Brazil, to acquire the equipment to produce biogas on her farm in the rural area of Afogados da Ingazeira, a municipality of 38,000 people in the state of Pernambuco in the Northeast region of Brazil.”We seek to promote energy, food and water autonomy to maintain more resilient agroecosystems, to coexist with climate change, strengthening community self-management with a special focus on the lives of women.” — Ita Porto

At first she did not have the cattle whose manure she needed to produce biogas, that enables her to save on liquefied petroleum gas, which costs 95 reais (20 dollars) for a 13-kg cylinder – a significant cost for poor families.

She brought manure from a neighboring farm that gave it to her for free, in an hour-long trip with her wheelbarrow, until she was able to buy her first cow and then another with loans from the state-owned Banco del Nordeste.

“Now I have more than enough manure,” she said happily as she welcomed IPS to her four-hectare farm where she and her husband have lived alone since their two children became independent.

Das Dores, as she is known, is an example among the 163 families who have benefited from the “sertanejos biodigesters” distributed by Diaconia in the sertão of Pajeú, a semiarid micro-region of 17 municipalities and 13,350 square kilometers in the center-north of Pernambuco.

Biofertilizer

In addition to using the biogas, she sells the manure after it has been subjected to anaerobic biodigestion that extracts the gases – the so-called digestate, a biofertilizer that she packages in one-kilo plastic bags, after drying and shredding it.

Every Saturday, she sells 30 bags at the agroecological market in the town of Afogados da Ingazeira, the municipal seat. At two reais (40 cents) a bag, she earns an extra income of 60 reais (12.50 dollars), on top of her sales of the various sweet cakes she bakes at home, at a cost reduced by the biogas, and of the seedlings she also produces.

The seedlings provided her with a new business opportunity. “The customers asked me if I didn’t also have fertilizer,” she said. The biodigester produces enough fertilizer to sell at the market and to fertilize the farm’s crops of beans, corn, fruit trees, flowers and different vegetables.

This diversity is common in family farming in Brazil’s semiarid Northeast, but even more so in the agroecological techniques that have expanded in this territory of one million square kilometers in the northeastern interior of the country, which has an arid biome highly vulnerable to climate change, subject to frequent droughts, and where there are areas in the process of desertification.

The Pajeú river basin is the micro-region chosen by Diaconia as a priority for its social and environmental actions.

On Lucineide Cordeiro’s small farm, cotton, corn, sesame, sunflower, cassava and fruit trees are alternated in the fields, as recommended by agroecology, which is on the rise on family farms in Brazil’s semiarid Northeast, which is threatened by longer and more severe droughts due to the climate crisis.

Energy and food security

“We seek to promote energy, food and water autonomy to maintain more resilient agroecosystems, to coexist with climate change, strengthening community self-management with a special focus on the lives of women,” Ita Porto, Diaconia’s coordinator in the Pajeu ecoregion, told IPS.

“The production of biogas on a rural family scale fulfills the needs of energy for cooking, sanitary disposal and treatment of animal waste and reduction of deforestation, in addition to increasing food productivity, with organic fertilizer, while bolstering human health,” said the 48-year-old agronomist.

More than 713 units of the “sertanejo biodigester”, a model developed by Diaconia 15 years ago, have been installed in Brazil. In addition to the 163 in the sertão do Pajeú, there are 150 in the neighboring state of Rio Grande do Norte and another 400 distributed in six other Brazilian states, financed by the Caixa Econômica Federal, a government bank focused on social questions.

“Hopefully the government will make it a public policy, as it has already done with the rainwater harvesting tanks in the semarid Northeast,” said Porto.

More than 1.3 million rainwater harvesting tanks for drinking water have already been built, but some 350,000 are still needed to make them universal in rural areas, according to the Articulation of the Semi-Arid (Asa), a network of 3,000 social organizations that spearheaded the transformative program.

Maria Das Dores examines the biofertilizer that comes out of the biodigester, without the gases from the animal manure. She sells this by-product at the agroecological market in the town of Afogados da Ingazeira, the seat of the municipality where her four-hectare farm is located, which earns her an average extra income of 12.5 dollars a week.

The value of manure

“One cow is enough to produce the biogas consumed in our stove,” said Lucineide Cordeiro, on her one-hectare farm where she grows cotton, corn, sesame seeds and fruit, in an interconnected agroecological system, along with chickens, pigs and fish in a pond.

She also has two oxen and two calves, which she proudly showed to IPS during the visit to her farm.

“Pig manure produces biogas more quickly, but I don’t like the stench,” the 37-year-old farmer who is the director of Women’s Policies at the Afogados da Ingazeira Rural Workers Union told IPS.

The difference in the crops before and after fertilization by the biodigester by-product is remarkable, according to her and other farmers in the municipality.

She tends to her many crops on her own, although she is sometimes helped by friends, and has several pieces of equipment such as a brushcutter and a micro-tractor.

“It’s the best invention,” says Lucineide Cordeiro, as she shows IPS the seeder created by the Japanese for small-scale farming, which allows her to sow in half a day the land that used to take her two days to plant, on her one-hectare farm in Afogados da Ingazeira, in Brazil’s semiarid Northeast. CREDIT: Mario Osava / IPS

“But the seeder is the best invention that changed my life, it was invented by the Japanese. Planting the seeds, which used to take me two days of work, I can now do in half a day,” Cordeiro said.

The seeder is a small machine pushed by the farmer, with a wheel filled with seeds that has 12 nozzles that can be opened or closed, according to the distance needed to sow each seed.

The emergence of appropriate equipment for family farming is recent, in a sector that has favored large farmers in Brazil.

Female protagonism clashes with male chauvinist violence

For the success of local family farming, the support of the Pajeú Agroecological Association (Asap), of which Cordeiro is a member and a “multiplier”, as the women farmers who are an example to others of good practices are called, is important.

In family farming the empowerment of women stands out, which in many cases was a response to sexist violence or oppression.

“The first violence I suffered was from my father who did not let me study. I only studied up to fourth grade of primary school, in the rural school. To continue, I would have had to go to the city, which my father did not allow. I got married to escape my father’s oppression,” said Cordeiro, who also separated from her first husband because he was violent.

After living in a big city with the father of her two daughters, she separated and returned to the countryside in 2019. “I was reborn” by becoming a farmer, she said, faced with the challenge of taking on that activity against the idea, even from her family, that a woman on her own could not possibly manage the demands of agricultural production.

Organic cotton, promoted and acquired in the region by Vert, a French-Brazilian company that produces footwear and clothing with organic inputs, has once again expanded in the Brazilian Northeast, after the crop was almost extinct due to the boll weevil plague in the 1990s.

In the case of Das Dores, a small, energetic, active woman, she has a good relationship with her husband, but she runs her own business initiatives. Thanks to what she earns she was able to buy a small pickup truck, but it is driven by her husband, who has a job but helps her on the farm in his free time.

“He drives because he refuses to teach me how, so I can’t go out alone with the vehicle and drive around everywhere,” she joked.

Solar Energy Useless Without Good Batteries in Brazil’s Amazon Jungle

Solar panels with a capacity to generate 30 kilowatts no longer work in the Darora Community of the Macuxi people, an indigenous group from Roraima, a state in the far north of Brazil. The batteries only worked for a month before they were damaged because they could not withstand the charge. CREDIT: Boa Vista City Hall

BOA VISTA, Brazil, Jan 25 2023 (IPS) – “Our electric power is of bad quality, it ruins electrical appliances,” complained Jesus Mota, 63. “In other places it works well, not here. Just because we are indigenous,” protested his wife, Adélia Augusto da Silva, of the same age.

The Darora Community of the Macuxi indigenous people illustrates the struggle for electricity by towns and isolated villages in the Amazon rainforest. Most get it from generators that run on diesel, a fuel that is polluting and expensive since it is transported from far away, by boats that travel on rivers for days.

Located 88 kilometers from the city of Boa Vista, capital of the state of Roraima, in the far north of Brazil, Darora celebrated the inauguration of its solar power plant, installed by the municipal government, in March 2017. It represented modernity in the form of a clean, stable source of energy.

A 600-meter network of poles and cables made it possible to light up the “center” of the community and to distribute electricity to its 48 families.

But “it only lasted a month, the batteries broke down,” Tuxaua (chief) Lindomar da Silva Homero, 43, a school bus driver, told IPS during a visit to the community. The village had to go back to the noisy and unreliable diesel generator, which only supplies a few hours of electricity a day.

“The solar panels were left here, useless. We want to reactivate them, it would be really good. We need more powerful batteries, like the ones they put in the bus terminal in Boa Vista.” — Lindomar da Silva Homero

Fortunately, about four months later, the Boa Vista electricity distribution company laid its cables to Darora, making it part of its grid.

Tuxaua (chief) Lindomar Homero of the Darora Community is calling for new adequate batteries to reactivate the solar power plant, because the electricity they receive from the national grid is too expensive for the local indigenous people.

Expensive energy

But indigenous people can’t afford the electricity from the distributor Roraima Energía, he said. On average, each family pays between 100 and 150 reais (20 to 30 dollars) a month, he estimated.

Besides, there are unpleasant surprises. “My November bill climbed to 649 reais” (130 dollars), without any explanation,” Homero complained. The solar energy was free.

“If you don’t pay, they cut off your power,” said Mota, who was tuxaua from 1990 to 2020.”In addition, the electricity from the grid fails a lot,” which is why the equipment is damaged.

Apart from the unreliable supply and frequent blackouts, there is not enough energy for the irrigation of agriculture, the community’s main source of income. “We can do it with diesel pumps, but it’s expensive; selling watermelons at the current price does not cover the cost,” he said.

“In 2022, it rained a lot, but there are dry summers that require irrigation for our corn, bean, squash, potato, and cassava crops. The energy we receive is not enough to operate the pump,” said Mota.

Achilles’ heel

Batteries still apparently limit the efficiency of solar energy in isolated or autonomous off-grid systems, with which the government and various private initiatives are attempting to make the supply of electricity universal and replace diesel generators.

Homero said that some of the Darora families who live outside the “center” of the village and have solar panels also had problems with the batteries.

Besides the 48 families in the village “center” there are 18 rural families, bringing the community’s total population to 265.

A solar plant was also installed in another community made up of 22 indigenous families of the Warao people, immigrants from Venezuela, called Warao a Janoko, 30 kilometers from Boa Vista.

But of the plant’s eight batteries, two have already stopped working after only a few months of use. And electricity is only guaranteed until 8:00 p.m.

“Batteries have gotten a lot better in the last decade, but they are still the weak link in solar power,” Aurelio Souza, a consultant who specializes in this question, told IPS from the city of São Paulo. “Poor sizing and the low quality of electronic charging control equipment aggravate this situation and reduce the useful life of the batteries.”

The low quality of the electricity supplied to Darora is due to the discrimination suffered by indigenous people, according to Adélia Augusto da Silva. The water they used to drink was also dirty and caused illnesses, especially in children, until the indigenous health service began to chemically treat their drinking water. CREDIT: Mario Osava/IPS

In Brazil’s Amazon jungle, close to a million people live without electricity, according to the Institute of Energy and the Environment, a non-governmental organization based in São Paulo. More precisely, its 2019 study identified 990,103 people in that situation.

Another three million inhabitants of the region, including the 650,000 people in Roraima, are outside the National Interconnected Electricity System. Their energy therefore depends mostly on diesel fuel transported from other regions, at a cost that affects all Brazilians.

The government decided to subsidize this fossil fuel so that the cost of electricity is not prohibitive in the Amazon region.

This subsidy is paid by other consumers, which contributes to making Brazilian electricity one of the most expensive in the world, despite the low cost of its main source, hydropower, which accounts for about 60 of the country’s electricity.

Solar energy became a viable alternative as the parts became cheaper. Initiatives to bring electricity to remote communities and reduce diesel consumption mushroomed.

But in remote plants outside the reach of the grid, good batteries are needed to store energy for the nighttime hours.

A unique case

Darora is not a typical case. It is part of the municipality of Boa Vista, which has a population of 437,000 inhabitants and good resources, it is close to a paved road and is within a savannah ecosystem called “lavrado”.

It is at the southern end of the São Marcos indigenous territory, where many Macuxi indigenous people live but fewer than in Raposa Serra do Sol, Roraima’s other large native reserve. According to the Special Secretariat for Indigenous Health (Sesai), there were 33,603 Macuxi Indians living in Roraima in 2014.

The Macuxi people also live in the neighboring country of Guyana, where there are a similar number to that of Roraima. Their language is part of the Karib family.

Although there are no large forests in the surrounding area, Darora takes its name from a tree, which offers “very resistant wood that is good for building houses,” Homero explained.

The community emerged in 1944, founded by a patriarch who lived to be 93 years old and attracted other Macuxi people to the area.

The progress they have made especially stands out in the secondary school in the village “center”, which currently has 89 students and 32 employees, “all from Darora, except for three teachers from outside,” Homero said proudly.

A new, larger elementary and middle school for students in the first to ninth grades was built a few years ago about 500 meters from the community.

Water used to be a serious problem. “We drank dirty, red water, children died of diarrhea. But now we have good, treated water,” said Adélia da Silva.

“We dug three artesian wells, but the water was useless, it was salty. The solution was brought by a Sesai technician, who used a chemical substance to make the water from the lagoon drinkable,” Homero said.

The community has three elevated water tanks, two for water used for bathing and cleaning and one for drinking water. There are no more health problems caused by water, the tuxaua said.

His current concern is to find new sources of income for the community. Tourism is one alternative. “We have the Tacutu river beach 300 meters away, great fruit production, handicrafts and typical local gastronomy based on corn and cassava,” he said, listing attractions for visitors.

Energy

The administration of President Gabriel Boric, a self-described environmentalist, is facing a growing rift between scientists, social leaders and energy companies that have differences with regard to the production of green hydrogen in Magallanes. The first wind turbines have already been installed in the Magallanes region, in the far south of Chile, such as these in Laredo Bay, east of Cabo Negro, where companies are pushing green hydrogen projects in a scenario where environmental costs are beginning to take center stage.

SANTIAGO, Oct 12 2022 (IPS) – In Magallanes, Chile’s southernmost region, doubts and questions are being raised about the environmental impact of turning this area into the world’s leading producer of green hydrogen.

The projects require thousands of wind turbines, several desalination plants, new ports, docks, roads and hundreds of technicians and workers, with major social, cultural, economic and even visual impacts.

“The scale of production creates uncertainties, heightened because there is no baseline. The question is whether Chile currently has the capacity to carry out large-scale green hydrogen projects.” — Jorge Gibbons

This long narrow South American country of 19.5 million people sandwiched between the Andes Mountains and the Pacific Ocean has enormous solar and wind energy potential in its Atacama Desert and southern pampas grasslands. This has led to a steady increase in electricity generation from clean and renewable sources.

In 2013, only six percent of the country’s total electricity generation came from non-conventional renewable sources (NCREs) – a proportion that climbed to 32 percent this year. Installed NCRE capacity in September reached 13,405 MW, representing 40.7 percent of the total. Of the NCREs, solar energy represents 23.5 percent and wind power 12.6 percent.

In Chile, NCREs are defined as wind, small hydropower plants )up to 20 MW), biomass, biogas, geothermal, solar and ocean energy.

According to the authorities, the wind potential of Magallanes could meet 13 percent of the world’s demand for green hydrogen, with a potential of 126 GW.

Green hydrogen is generated by low-emission renewable energies in the electrolysis of water (H2O) by breaking down the molecules into oxygen (O2) and hydrogen (H2). It currently accounts for less than one percent of the world’s energy.

However, it is projected as the energy source with the most promising future to advance towards the decarbonization of the economy and the replacement of hydrocarbons, due to its potential in electricity-intensive industries, such as steel and cement, or in air and maritime transportation.

The National Green Hydrogen Strategy, launched in November 2021 by the second government of then right-wing President Sebastián Piñera (2018-2022), seeks to increase carbon neutrality, decrease Chile’s dependence on oil and turn this country into an energy exporter.

The government of his successor, leftist President Gabriel Boric, in office since March, created an Interministerial Council of the Green Hydrogen Industry Development Committee, with the participation of eight cabinet ministers.

A spokesperson from the Ministry of Energy told IPS that “this committee has agreed to bring forward, from 2025 to 2022, the update of the National Green Hydrogen Strategy and the new schedule for the allocation of state-owned land for these projects.”

“We will promote green hydrogen in a cross-cutting manner, with an emphasis on harmonious, fair and balanced local development. By bringing forward the update of the strategy, we seek to generate certainty for investors and to begin to create the necessary regulatory framework for the growth of this industry in our country,” he said.

In the area known as Cabo Negro, in the Chilean region of Magallanes, several companies have installed wind turbines to generate wind energy. The installation of thousands of turbines will affect the landscape of Magallanes and environmentalists believe it will impact many birds that migrate annually to this southern region.

Warnings from environmentalists

In a letter to the president, more than 80 environmentalists warned of the risk of turning “Magallanes y La Antarctica Chilena” – the region’s official name – into an environmental sacrifice zone for the development of green hydrogen.

“The energy transition cannot mean the sacrifice of migratory routes of birds that are in danger of extinction, otherwise it would not be a fair or sustainable transition,” said the letter, which has not yet received a formal response.

Environmentalists argue that the impact is not restricted to birds, but also affects whales that breed there, due to the effects of desalination plants, large ports and harbors.

Carmen Espoz, dean of science at the Santo Tomás University, who signed the letter, told IPS that “the main warning that we have tried to raise with the government, and with some of the companies with which we have spoken, is that there is a need for zoning or land-use planning, which does not exist to date, and for independent, quality baseline information for decision-making” on the issue.

Espoz, who also heads the Bahía Lomas Center in Magallanes, based in Punta Arenas, the regional capital, clarified that they are not opposed to the production of green hydrogen but demand that it be done right.

It is urgently necessary, she said in an interview in Santiago, to “stop making decisions at the central level without consultation or real participation of the local communities and to generate the necessary technical information base.”

The signatories asked Boric to create a Regional Land Use Plan with Strategic Environmental Assessment to avoid unregulated development of projects.

“We are not only talking about birds, but also about profound social, cultural and environmental impacts,” said Espoz, who argued that the model promoted by the government and green hydrogen developers “does not have a social license to implement it.”

The bird question

Prior to this letter to Boric, the international scientific journal Science published a study by Chilean scientists warning about potential impacts of wind turbines on the 40 to 60 species of migratory birds that visit Magallanes.

“It is estimated that the installation of wind turbines along the migratory paths of birds could affect migratory shorebird populations, which is especially critical in the cases of the Red Knot (Calidris canutus rufa) and the Magellanic Plover (Pluvianellus socialis),” said Espoz.

Both species, she said, “are endangered, as is the Ruddy-headed Goose (Chloephaga rubidiceps).”

She added that if 13 percent of the world’s green hydrogen is to be generated in southern Chile, some 2,900 wind turbines will have to be installed by 2027, “which could cause between 1,740 and 5,220 collisions with bird per year.”

Jorge Gibbons, a marine biologist at the University of Magallanes, based in Punta Arenas, said the big problem is that Magallanes does not have a baseline for environmental issues.

Gibbons believes it would take about two years to update the data on the dolphin and Southern Right Whale (Eubalaena australis) populations

“The greatest risks to dolphins will be seen in the Strait of Magellan. I am talking about Commerson’s Dolphins (Cephalorhynchus commersonii), which are only found there in Chile and whose population is relatively small,” he said.

He proposed studying the route to ports and harbors of these species and to analyze how they breed and feed.

“The issue is how noise disturbs them or interrupts their routes. These questions are still unanswered, but we know some things because it is the best censused species in Chile,” he explained.

According to Gibbons, the letter to Boric is timely and will help reduce uncertainty because “the process is just beginning and the scientific and local community are now wondering if the plan will be well done.”

Conflict of interests

The partnership between HIF Chile and Enel Green Power Chile withdrew from the Environmental Evaluation System the study of the Faro del Sur Wind Farm project, involving an investment of 500 million dollars for the installation of 65 three-blade wind turbines on 3,791 hectares of land in Magallanes.

The study was presented in early August with the announcement that it was “a decisive step for the future of green hydrogen-based eFuels.”

But on Oct. 6, its withdrawal was announced after a series of observations were issued by the Magallanes regional Secretariat of the Environment.

“The observations of some public bodies in the evaluation process of this wind farm exceed the usual standards,” the consortium formed by the Chilean company HIF and the subsidiary of the Italian transnational Enel claimed in a statement.

The companies argued that “the authorities must provide clear guidelines to the companies on the expectations for regional development, safeguarding the communities and the environment.

“In light of these exceptional requirements, it is necessary to understand which requirements can be incorporated and which definitely make projects of this type unfeasible in the region,” they complained.

The government reacted by stating that it is important to remember that Faro del Sur is the first green hydrogen project submitted to the environmental assessment process in Magallanes.

“During the process, some evaluating entities made observations on the project, so the owners decided to withdraw it early, which does not prevent them from reintroducing it when they deem it convenient,” the Ministry of Energy spokesperson told IPS.

He added that the ministry stresses “the conviction to develop the green hydrogen industry in the country and that this means sending out signals, but in no case should this compromise environmental standards and citizen participation in the evaluation processes.”

CUZCO, Peru , Dec 22 2021 (IPS) – “When I was a little girl we didn’t suffer from water shortages like we do now. Today we are experiencing more droughts, our water sources are drying up and we cannot sit idly by,” Kely Quispe, a small farmer from the community of Huasao, located half an hour from Cuzco, the capital of Peru’s ancient Inca empire, told IPS.

She is one of the 80 members of the Agroecological School of the Flora Tristan Peruvian Women’s Center, a non-governmental institution that has worked for the recovery of water sources through traditional techniques known as seeding and harvesting water in this part of the southern Andean region of Cuzco.

Muñapata, Huasao and Sachac are the three rural Quechua-speaking communities in the province of Quispicanchi, located between 3150 and 3800 meters above sea level, that have so far benefited from the project. The feminist-oriented institution promotes solutions based on nature and community work to address the problem of water scarcity and inadequate water use practices.

“We want to boost water security as well as gender equality because they are two sides of the same coin,” Elena Villanueva told IPS. On Dec. 14 she presented in this city the results of the initiative whose first phase was carried out in 2020 and 2021, with the support of the Basque Development Cooperation Agency and Mugen Gainetik, an international association for cooperation with countries of the developing South also based in Spain’s northern Basque region.

According to the National Water Authority (ANA), Peru is the eighth country in the world in terms of water availability, with a rich hydrodiversity of glaciers, rivers, lakes, lagoons and aquifers. However, various factors such as inefficient management of water and uneven territorial distribution of the population, in addition to climate change, make it impossible to meet consumption demands.

“The lack of water severely affects families in rural areas because they depend on small-scale agriculture for their livelihoods. The melting of glaciers as well as the increase in the frequency and intensity of droughts due to climate change are reducing water availability,” Villanueva explained.

This impact, she said, is not neutral. Because of the gender discrimination and social disadvantages they face, it is rural women who bear the brunt, as their already heavy workload is increased, their health is undermined, and their participation in training and decision-making spaces is further limited.

“Moreover, although they are the ones who use water to ensure food, hygiene and health, and to irrigate their crops, they are not part of the decision-making with regard to its management and distribution,” she stressed.

The expert said that precisely in response to demand by the women farmers at the Agroecological School, where they receive technical and rights training, they are focusing on reviving water harvesting techniques used in ancient Peru, while promoting the equal participation of women in rural communities in the process.

She said that approximately 700 families living in poverty, some 3,500 people – about 11 percent of the population of the three communities – will benefit from the works being carried out.

Harvesting water

So far, these works are focused on the afforestation of 15 hectares and the construction of six “cochas” – the name for small earthen ponds, in the Quechua language – and an infiltration ditch, as part of a plan that will be expanded with other initiatives over the next two years.

The ditch, which is one kilometer long in 10-meter stretches, 60 centimeters deep and 40 centimeters wide and is located in the upper part of the community, collects rainwater instead of letting it run down the slopes.

The technique allows water to infiltrate slowly in order to feed natural springs, high altitude wetlands or small native prairies, as well as the cochas.

In their communal work, villagers use local materials and greenhouse thermal blankets to help retain water. In addition, they have used extracted soil to raise the height of the ditch, to keep rainwater from running over the top.

Although the ditch has been receiving rainwater this month (the rainy season begins in November-December), the ecosystem impact is expected to be more visible in about three years when the cocha ponds have year-round water availability, helping villagers avoid the shortages of the May-October dry season.

Several community members explained to IPS that they will now be able to harvest water from the ditch while at the same time caring for the soil, because heavy rain washes it away and leaves it without nutrients. Some 150 agricultural plots will also benefit from a sprinkler irrigation system, thanks to the project.

Since agriculture is the main livelihood of the families and this activity depends on rainwater, the main impact will be the availability of water during the increasingly prolonged dry periods to irrigate their crops, ensure harvests and avoid hunger, for both villagers and their livestock.

Eucalyptus and pine, huge consumers of water

The mayor of the Sachac community, Eugenio Turpo Quispe, told IPS that this is the first time that water seeding and harvesting practices have been carried out in his area. “We had not had the opportunity before; these works have begun thanks to the women who proposed forestation and the construction of cochas and ditches,” he said.

The local leader lamented that due to misinformation, two decades ago they planted pine and eucalyptus in the highlands of his community. “They have dried up our water sources, and when it rains the water disappears, it does not infiltrate. Now we know that out of ten liters of rain that falls on the ground, eight are absorbed by the eucalyptus and only two return to the earth,” he explained during the day that IPS spent in the community.

Turpo Quispe said they had seen forestation and construction of cochas and ditches in other communities, but did not know how to replicate them, and that only through the Flora Tristán Center’s project have they been able to implement these solutions to tackle the serious problem of shrinking water sources.

In Sachac, the three techniques have been adopted with the participation of women and men in communal work that began at six in the morning and ended at four in the afternoon. “Side by side we have been planting native plants, digging ditches and hauling stones for the cochas,” the mayor said proudly.

In this community, 9,000 seedlings of queuñas (Polylepis) and chachacomos (Escallonia Resinosas) – tree species that were used in the times of the ancient Inca empire – were planted. “These trees consume only two liters of rainwater and give eight back to Pachamama (Mother Earth),” Turpo Quispe said. As part of the project, the community has built fences to protect crops and has relocated grazing areas for their animals.

“We have planted seedlings and in 10 or 15 years our children and grandchildren will see all our hills green and with living springs so that they do not suffer a lack of water,” the mayor said.

Kely Quispe from the community of Huasao is equally upbeat: “With water we can irrigate our potatoes, corn and vegetables; increase our production to have enough to sell and have extra money; take care of our health and that of the whole family, and prevent the spread of covid.”

“But just as we use water for life, it is also up to us to participate on an equal footing with men in irrigation committees and community councils to decide how it is distributed, conserved and managed,” she added.

The decade of water security

Villanueva of the Flora Tristán Center said it was important for the country’s local and regional authorities to commit to guaranteeing water security in rural areas within the framework of the Sustainable Development Goals (SDGs).

The International Decade for Action: Water for Sustainable Development was declared for 2018-2028 by the United Nations and SDG6 is dedicated to water and sanitation, to ensure universal and equitable access for all, protect and restore water-related ecosystems, and support the participation of local communities in improving management and sanitation.

“At the national level, public policies aimed at seeding and harvesting water should be strengthened because they revive the communities’ ancestral knowledge, involving sustainable practices with low environmental impact that contribute to guaranteeing the food security of families,” she said.

However, Villanueva remarked, in order to achieve their objectives, these measures must not only promote equal participation of men and women, but must also be accompanied by actions to close the gender gap in education, access to resources, training and violence that hinder the participation and development of rural women.
