COQUIMBO, Chile , Sep 18 2023 (IPS) – The reuse of treated wastewater in vulnerable rural areas of Chile’s arid north is emerging as a new resource for the inhabitants of this long, narrow South American country.

The Coquimbo region, just south of the Atacama Desert, one of the driest in the world, is suffering from a severe drought that has lasted 15 years.

According to data from the Meteorological Directorate, a regional station located in the Andes Mountains measured 30.3 millimeters (mm) of rain per square meter this year as of Sept. 10, compared to 213 mm in all of 2022.

“Rural localities today are already reusing wastewater or gray water. This is going to happen, with or without us, with or without a law. The need for water is so great that the communities are accepting the use of treated wastewater.” — Gerardo Díaz

At another station, in the coastal area, during the same period in 2023, rainfall stood at 10.5 mm compared to the usual level of 83.2 mm.

Faced with this persistent level of drought, vulnerable rural localities in Coquimbo, mostly dedicated to small-scale agriculture, are emerging as a new example of solutions that can be replicated in the country to alleviate water shortages.

The aim is to not waste the water that runs down the drains but to accumulate it in tanks, treat it and then use it to irrigate everything from alfalfa fields to native plants and trees in parks and streets in the localities involved. It is a response to drought and the expansion of the desert.

“We were able to implement five wastewater treatment projects and reuse 9.5 liters per second, which is, according to a comparative value, the consumption of 2,700 people for a year or the water used to irrigate 60 hectares of olive trees,” said Gerardo Díaz, sustainability manager of the non-governmental Fundación Chile.

These five projects, promoted by the Fundación Chile as part of its Water Scenarios 2030 initiative, are financed by the regional government of Coquimbo, which contributed the equivalent of 312,000 dollars. Of this total, 73 percent is dedicated to enabling reuse systems, for which plants in need of upgrading but not reconstruction have been selected.

The common objective of these projects, which together benefit some 6,500 people, is the reuse of wastewater for productive purposes, the replacement of drinking water or the recharge of aquifers.

Díaz told IPS that the amount of reuse obtained is significant because previously this water was discharged into a stream, canal or river where it was perhaps captured downstream.

A successful pilot experience

In Coquimbo, which has a regional population of some 780,000 people, there are 71 water treatment plants, most of which use activated sludge and almost all of which are linked to the Rural Drinking Water Program (APR) of the state Hydraulic Works Directorate.

Activated sludge systems are biological wastewater treatment processes using microorganisms, which are very sensitive in their operation and maintenance and rural sectors do not have the capacity to maintain them.

“Most of these treatment plants are not operating or are operating inefficiently,” Diaz acknowledged.

But one of the plants, once reconditioned, has served as a model for others since 2018. Its creation allowed Dionisio Antiquera, a 52-year-old agricultural technician, to save his alfalfa crop.

“We have had a water deficit for years. This recycled water really helps us grow our crops on our eight hectares of land,” he said in the middle of his alfalfa field in Cerrillos de Tamaya, one of the Coquimbo municipalities that IPS toured for several days to observe five wastewater reuse projects.

He explained that using just reused water he was able to produce six normal alfalfa harvests per year with a yield per hectare of 100 25-kg bales.

“That’s 4500 to 4800 bales in the annual production season,” he said proudly.

These bales are easily sold in the region because they are cheaper than those of other farmers.

The water he uses comes from an APR plant that has 1065 users, 650 of whom provide water, including Antiquera.

On one side of his alfalfa field is a plant that accumulates the sludge that is dehydrated in pools and drying courts, and on the other side, the water is chlorinated and runs into another pond in its natural state.

“This water works well for alfalfa. It is hard water that has about 1400 parts per million of salt. Then it goes through a reverse osmosis process that removes the salt and the water is suitable for human consumption,” the farmer explained.

In Chile, treated wastewater is not considered fresh water or water that can be used directly by people, and its reuse is only indirect.

Antiquera sold half a hectare to the government to install the plant and in exchange uses the water obtained and contributes 20 percent to the local APR.

He recently extended his alfalfa field to another seven hectares, thanks to his success with treated water.

Flowers and trees also benefit

In Villa Puclaro, in the Coquimbo municipality of Vicuña, Raúl Ángel Flores, 55, has an ornamental plant nursery.

“I’ve done really well. My nursery has grown with just reuse water….. I have more than 40,000 ornamental, fruit, native and cactus plants. I deliver to retailers in Vicuña and Coquimbo,” a port city in the region, he told IPS.

The nursery is 850 square meters in size, and has an accumulation pond and pumps to pump the water. He has now rented a 2,500-meter plot of land to expand it.

Flores explained to IPS that he manages the nursery together with his wife, Carolina Cáceres, and despite the fact that they have two daughters and a senior citizen in their care, “we make a living just selling the plants…I even hired an assistant,” he added.

In the southern hemisphere summer he uses between 4,000 and 5,000 liters of water a day for irrigation.

“I have water to spare. Here it could be reused for anything,” he said.

Joining the project made it possible for Flores to make efficient use of water with a business model that in this case incorporates a fee for the water to the plant management, which is equivalent to 62 cents per cubic meter used.

Eliminating odors, and creating new gardens

In the community of Huatulame, in the municipality of Monte Patria, Fundación Chile built an artificial surface wetland to put an end to the bad odors caused by effluents from a deficient waste-eater earthworm vermifilter treatment plant.

“This wetland has brought us peace because the odors have been eliminated. For the past year people have been able to walk along the banks of the old riverbed,” Deysy Cortés, 72, president of the APR, told IPS.

The municipality of Monte Patria is financing the repair of the plant with the equivalent of 100,000 dollars.

“The sprinklers will be changed, the filtering system will be replaced, and sawdust and worms will be added. It will be up and running in a couple of months,” explained agronomist Jorge Núñez, a consultant for Fundación Chile.

As in other renovated plants, safe infiltration of wastewater is ensured while the project simultaneously promotes the protection of nearby wells to provide water to the villagers.

Cortés warned of serious difficulties if no more rain falls in the rest of 2023, despite the relief provided by the plant for irrigation.

“I foresee a very difficult future if it doesn’t rain. We will go back to what we experienced in 2019 when in every house there were bottles filled with water and a little jug to bathe once a week,” she said.

During a recent crisis, the local APR paid 2500 dollars to bring in water from four 20,000-liter tanker trucks.

In Plan de Hornos, a town in the municipality of Illapel, irrigation technology was installed using reused water instead of drinking water to create a green space for the community to enjoy.

The project included water taps in people’s homes for residents to water trees and flowers.

Arnoldo Olivares, 59, is in charge of the plant, which has 160 members.

“I run both systems,” he told IPS. “I pour drinking water into the pond. After passing through the houses, the water goes into the drainage system, where there is a procedure to reclaim and treat it.”

“This water was lost before, and now we reuse it to irrigate the saplings. We used to work manually, now it is automated. It’s a tremendous change, we’re really happy,” he said.

Antiquera the alfalfa farmer is happy with his success in Cerrillos de Tamaya, but warns that in his area 150 to 160 mm of rainfall per year is normal and so far only 25 mm have fallen in 2023.

“The water crisis forces us to find alternatives and to be 100 percent efficient. Not a drop of water can be wasted. They have forecast very high temperatures for the upcoming (southern hemisphere) summer, which means that plants will require more water in order to thrive,” he said.

Díaz, the sustainability manager of Fundación Chile, said the Coquimbo projects are fully replicable in other water-stressed areas of Chile if a collaborative model is used.

He noted that “in Chile there is no law for the reuse of treated wastewater. There is only a gray water law that was passed years ago, but there are no regulations to implement it.”

He explained, however, that due to the drought, “rural localities today are already reusing wastewater or gray water. This is going to happen, with or without us, with or without a law. The need for water is so great that the communities are accepting the use of treated wastewater.”

The governor of Coquimbo, Krist Naranjo, argued that “a broader vision is needed to value water resources that are essential for life, especially in the context of global climate change.”

“We’re working on different initiatives with different executors, but the essential thing is to value the reuse of graywater recycling,” she told IPS from La Serena, the regional capital.

SUCHITOTO, El Salvador , Jul 25 2023 (IPS)

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.

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.

Champad, India, Jul 4 2023 (IPS)

Simita Devi spent over ten days in a government-run hospital a year ago anxiously watching her critically ill nine-year-old daughter, Gudiya, who was diagnosed with typhoid.

Gudiya was so sick she even went into a coma for a day. Medical staff attending to the child said she contracted the disease from drinking contaminated water.

After being discharged, Devi’s main worry was to get safe drinking water for her ailing daughter.

She was advised not to consume water from village wells or untested sources like river streams or springs.

Hailing from Champad, a tribal village in India’s Jharkhand state, Devi works as a daily wage labourer alongside her husband. With a limited income, Devi couldn’t afford packaged drinking water for her daughter.

She then decided to boil the water using firewood to make it safe to drink. But to get the firewood, she had to trek the treacherous terrains of the nearby forests – a long, difficult work and the fear of wild animals loomed.

It was not Devi alone impacted by contaminated water, it was making many people in her village ill, and there was nothing the inhabitants could do about it.

According to government records, 80% of India’s rural drinking water comes from underground sources. One-third of India’s 600 districts do not have safe drinking water because fluoride, iron, salinity, and arsenic concentrations exceed tolerance levels. India’s water quality is poor, ranking at 120 of 122 nations.

Experts believe that the source of these heavy metals is industrial waste being dumped untreated into water systems and nitrates which surface due to excessive and prolonged use of fertilizers. The government estimates that every year, over one lakh (100,000) people die of waterborne diseases in the country.

Champad, a village inhabited by a tribal community, has 105 households per the 2011 census. Until 2022, the community depended on only two tube wells as their source of drinking water. However, these tube wells often experienced malfunctions, leaving the villagers with no choice but to fetch water from a nearby river or pond. Consequently, there has been a rise in waterborne diseases, particularly affecting the health of women and children. The need to travel long distances for safe drinking water has increased women’s workload, increasing their workload.

Perturbed by the threat of waterborne diseases, the village locals congregated earlier this year to try to find a solution. They at first visited the local politicians for help. Then they headed towards government offices. “Nothing happened—absolutely nothing. We were virtually left high and dry. Except for God, no one is there to help us. At times, we were told to wait, and at times, we were told that government funding wasn’t available. But we were slowly dying. Our children are suffering in front of our own eyes,” Ram Singh, a local villager at Champad, told IPS.

Earlier this year, a team from a non-governmental agency working to uplift rural areas in India visited the village to assess the villagers’ hardships.

The agency then mooted the idea of a solar water tower in the village. The villagers were made aware of the process involved in the tower’s construction and that government approval for the facility was needed.

The village representatives were taken on board, and a proposal was submitted to the water department of the district.

“Government liked the idea, and it was readily approved. The entire village worked together to make the project a success story,” says a member of the humanitarian agency who wished to remain anonymous.

The towers were equipped with solar panels, enabling them to operate sustainably and with minimal environmental impact. The selection of sites for the towers was a collaborative effort involving the village communities. The first solar water tower was constructed in February 2023, while work on the other two towers is still ongoing. As a result, 45 families now directly benefit from the convenience of having clean drinking water channelled to their homes through pipelines. The water provided is of good quality and considered safe, in contrast to the open well water that was previously relied upon. This development has significantly alleviated the burden on women, who no longer have to travel long distances to fetch water from various sources.

The impact of this intervention was significant. The community’s health improved, and they were no longer at risk of waterborne illnesses. The women and children, who were often responsible for collecting water from distant sources, could now spend their time on other activities. The community’s overall quality of life improved, and they could focus on their livelihoods and education.

For Simita Devi, the facility is no less than a major solace in her life. She excitedly uses this water for drinking and thanks God for such an endeavour.

“Safe water means life for us. The solar tower has become a messiah for poor villagers like us. We will cherish the moments for life when we find its water coming to our homes,” Devi told IPS.

Biodigesters Boost Family Farming in 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.

“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.

Energy

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.

“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,” said Homero, referring to one of the many solar plants that the city government installed in the capital.

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.
