NITERÓI, Brazil, Oct 20 (IPS) – Houses with balconies facing the street or the surrounding hills, when they are not hidden behind high walls, reflect a neighborhood where people live on the shore of a lagoon but reject the landscape it offers.

Piratininga, a 2.87 square kilometer coastal lagoon in the southern part of the Brazilian city of Niterói, began to change after several decades of uncontrolled urban growth with no care for the natural surroundings, in what has become a neighborhood of 16,000 inhabitants.

Garbage, polluted water, construction debris and bad odors hurt the landscape and the quality of life that is sought when choosing a lagoon and green hills as a place to build a year-round or weekend residence.

The accumulated sludge at the bottom of the lagoon is 1.6 meters thick, on average, resulting from both pollution and natural sedimentation.

“That’s what explains those houses that turn their backs to the lagoon,” explained Dionê Castro, coordinator of the Sustainable Oceanic Region Program (PRO Sostenible) of the city government of Niterói, a municipality of 482,000 people separated from the city of Rio de Janeiro only by Guanabara Bay.

Oceânica is one of the five administrative zones of the municipality, locally called regions, which includes 11 neighborhoods in the southern part, on the open sea coast, in contrast to others on the shore of the bay or inland areas without beaches. With two lagoons and a good part of the Atlantic Forest still preserved, the area stands out for its nature.

PRO Sostenible, which was founded in 2014, seeks to restore environmental systems and to ensure better and more sustainable urbanization in the area. Its actions are based on a systemic approach and nature-based solutions.

Natural clean-up of the water

The program’s flagship project is the Orla Piratininga Alfredo Sirkis Park, which pays homage to a leader of the environmental movement, former national lawmaker and former president of the Green Party, as well as journalist and writer, who died in 2020.

The park, known by its acronym POP, has the mission of recovering and protecting the ecosystems associated with the Piratininga Lagoon, in addition to fostering a sense of belonging to the environment and its surroundings. For this reason, the participation of the local residents in all stages of the project has been and continues to be a basic principle.

It comprises an area of 680,000 square meters, the largest in Brazil in nature-based solutions projects, with 10.6 kilometers of bicycle paths, 17 recreational areas and a 2,800 square meter Ecocultural Center.

To bring residents and visitors closer to the local environment, the plan is to complete three three-story lookout points – two of which have already been built – and piers reaching into the lagoon, part of which can be used for fishing, as fish still inhabit the lagoon despite the pollution of recent decades.

The first section, known as Haciendita Cafubá, was inaugurated on Jun. 17, with a water filtration system for the Cafubá River, one of the three that flow into the lagoon, a lookout point, piers, a bicycle path and even a nursery for newborn crocodiles in a special fenced-in area.

“I went to see if I could find the crocodiles, my son made me walk down the street, he loves animals… I never thought I would see what I saw… I went to the beginning of the Haciendita, I saw fish where there was nothing living before, I saw flowers where there was only mud, I saw life where nature was already dead without any hope. Congratulations for tolerating us, that community is tough.”

This is the testimony of a resident, addressed to the head of PRO Sostenible. The park has had a large number of visitors since before its inauguration, attracted by flora and fauna that had long since disappeared from the shores of the lagoon.

The technology used to clean the waters is known around the world but has not been widely used in Brazil. It is based on filter gardens, in which layers of gravel and permeable substrates serve as a base for macrophytes, aquatic plants that live in flooded areas and are visible on the surface.

The plants filter the water in a process that does not require chemical inputs.

A special spillway receives the waters of the Cafubá, which conducts and controls them to give greater efficiency to the next pond, the sedimentation pond, the first step in cleaning the polluted waters by reducing the solid material produced by erosion and garbage thrown into the riverbed.

After the sedimentation basins, the water passes through three filtering gardens before flowing into the lagoon.

Biologists and environmental managers Heloisa Osanai and Andrea Maia are photographed at the Tibau Island lookout point at the western end of the Piratininga Lagoon in southeastern Brazil.

Plantfilters

Twelve species of macrophytes are used in the filtration process, but the variety has been reduced due to maintenance difficulties. “We use only Brazilian species, and no exogenous species,” said Heloisa Osanai, a biologist specialized in environmental management and one of the 17 employees of PRO Sostenible.

Examples include water lettuce and water lilies with orange flowers.

“One of the effects of the water treatment is the reduction of mosquitoes, which is important to local residents, who used to burn dry vegetation in an attempt to drive away the insects. People no longer build bonfires in the evenings. The filter gardens attract dragonflies that eat the mosquitoes,” said Osanai.

In the larger Jacaré River, 11 filtering gardens were created, which operate in sequence and whose size was designed for greater efficiency, said Andrea Maia, another biologist and environmental manager of the team.

Filter gardens beautify the environment and expel mosquitoes, with macrophyte aquatic plant species that clean the water, in addition to decontaminating the Piratininga lagoon, restoring fishing and local tourism in a long-neglected ecosystem of Niteroi, in southeastern Brazil.

Awards and results

PRO Sostenible has already won several national and international awards. It was named one of the three best environmental sustainability programs in Latin America and the Caribbean in the Smart Cities 2022 award.

This year it won another award from Smart Cities Latin America, as the best in Sustainable Urban Development and Mobility. The Park also won awards for valuing biodiversity, from the Federation of Industries of Rio de Janeiro, and another as an environmental project, from the São Paulo city government, for contributing to the Sustainable Development Goals of the 2030 Agenda.

In addition to the Park, the program has inaugurated a Sports and Leisure Center on the island of Tibau, on the other side of the Piratininga Lagoon, closer to the sea.

As part of this project, sports fields, a playground and a lookout point have been built, while an invasive tree, the white lead tree (Leucaena leucocephala), native to Mexico and Central America, which dominated the island’s vegetation, has been gradually replaced with local species.

The systemic thinking that guides PRO Sostenible is based on three pillars, explained Dionê Castro.

First is the complexity of local ecosystems and of the projects being implemented, focusing on the environmental, natural, social and cultural dimensions.

In second place is what is called “intersubjectivity”, which takes into account new paradigms of science, leaving behind “simplistic and Cartesian views…The changes do not come from outside, but from local residents, with public input from the conception of the project to its execution,” said the geographer who holds a doctorate in environmental management.

The third pillar is irreversibility. The lagoon and its ecosystems will not return to their original state, “to zero,” but will be cleaned up as much as possible to reach a “new equilibrium,” she said.

Local support for the environmental project led to solutions in different areas, such as the regularization of real estate in the favelas or shantytowns, the improvement of health, the revitalization of fishing, and even the creation of a fishermen’s association.

“It’s environmental justice on the march,” Castro summed up.

‘Passion Seeds’ Fertilize Brazil’s Semiarid Northeast — Global Issues

ESPERANÇA, Brazil, Jul 14 (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.

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.

The Dark Side of Wind and Solar Farms as Sustainable Energy in Brazil — Global Issues

A view of the Canoas Wind Farm, owned by Neoenergia, the Brazilian subsidiary of Spain’s Iberdrola. Several wind farms with hundreds of turbines have already been built in the mountains of the Seridó mountain range, which vertically cross the state of Paraíba, in the Northeast region of Brazil, and are continuing to expand.

SANTA LUZIA, Brazil, Jul 07 (IPS) – “Anxiety, insomnia and depression have become widespread. We don’t sleep well, I wake up three, four times a night,” complained Brazilian farmer Roselma de Melo Oliveira, 35, who has lived 160 meters from a wind turbine for eight years.

Her story illustrates the ordeal of at least 80 families who decided to hire a lawyer to demand compensation from the company that owns the Ventos de Santa Brigida wind farm complex in Caetés, a municipality of 28,000 inhabitants in the state of Pernambuco, in the Northeast region of Brazil.

Dozens of other families affected by the proximity of the wind towers have not joined the legal action, largely because they fear losing the rental income from part of their land where one or more wind turbines have been erected.

The company pays them about 290 dollars for each wind tower, which represents 1.5 percent of the electricity generated and sold, according to Oliveira. Those who were not offered or did not accept the lease are left with the damage and no profits.

Built in 2015 by the national company Casa dos Ventos and sold the following year to the British corporation Cubico Sustainable Investments, the set of seven wind farms, consisting of 107 wind turbines 80 meters high, has a total installed capacity of 182 megawatts, enough to supply 350,000 homes.

The wind energy boom has intensified in recent years in Brazil’s Northeast region, which accounts for more than 80 percent of the wind electricity generated in the whole country.

Severino Olegario, a small farmer impoverished by a plague that destroyed the local cotton crop, took advantage of the arrival of the wind towers on his family’s mountainous land to become the owner of an open-air restaurant, now a tourist attraction in the municipality of Santa Luzia, in the Northeastern Brazilian state of Paraíba.

Wind power boom

This expansion will be accelerated by plans to produce green hydrogen, which requires a large amount of renewable energy for electrolysis, the technology of choice. The region’s enormous wind and solar potential, in addition to its relative proximity to Europe, the great consumer market of green hydrogen, puts the Northeast in a strong position as a supplier of the so-called fuel of the future.

As a result, large energy projects are proliferating in the region, which is mostly semiarid and almost always sunny. The giant parks have triggered local resistance, due to the social and environmental impacts, which are felt more intensely in the Northeast, where small rural properties are the norm.

Brazil currently has 191,702 megawatts of installed capacity, including 53.3 percent hydroelectric, 13.2 percent wind and 4.4 percent solar. The goal is for wind, solar and biomass to contribute 23 percent of the total by 2030, with the Northeast as the epicenter of the production of renewable sources.

“We are not against wind energy, but against the way these large projects are implemented, without studying or avoiding their impacts,” Oliveira said. Renewable sources are not always clean and sustainable, say activists, especially movements led by women in the Northeast.

“Because they are considered low-impact, wind and solar farms obtain permits for implementation and operation more quickly and at a low cost, without in-depth studies,” said José Aderivaldo, a sociologist and secondary school teacher in Santa Luzia, a municipality of 15,000 inhabitants in the semiarid zone of the Northeastern state of Paraíba.

“But solar energy has a greater impact, it is more invasive. A wind farm has little impact on livestock, which do lose a lot of space to solar, more extensive in terms of the land it occupies,” he told IPS.

His field of observation is the Neoenergía company’s Renewable Complex, a project that combines wind power, with 136 wind turbines in the Chafariz complex in the mountains, and 228,000 photovoltaic panels in the Luzia Park on the plains. The former generates more electricity at night, the latter during the day.

In total, they cover 8,700 hectares in Santa Luzia and three other neighboring municipalities and can generate up to 620.4 megawatts, most of it – 471.2 megawatts – coming from the wind in the mountains. They can supply electricity to 1.3 million housing units and avoid the emission of 100,000 tons of carbon dioxide gas, according to the company, a subsidiary of Spain’s Iberdrola.

One of the impacts was a reduction in the local capacity for the production of cheap protein from livestock farming adapted for centuries to the local ecosystem, in addition to extracting rocks for the construction of wind towers and damaging local roads with trucks for their transport, lamented João Telésforo, an engineer and retired professor from the public Federal University of Rio Grande do Norte.

“Neoenergía carried out all the socio-environmental impact studies rigorously in accordance with the country’s current legislation and global best practices. The distance between the homes and the wind turbines is in compliance with the law,” the company responded to IPS in writing, in response to questions about criticism of its activities.

Marizelda Duarte da Silva, vice-president of the Esperança Rural Workers Union, is one of the leaders of the women’s resistance to the installation of wind farms in the mountains of the Borborema Plateau, coveted for its strong, regular winds, in the state of Paraíba, in Brazil’s Northeast region.

“In addition, it only leases the land, without purchasing it, which means people stay in their homes and in the countryside, and owners receive payments according to the contracts, with transparency, contributing to income distribution and local quality of life,” it added.

Local complaints

But Pedro Olegario, 73, laments that the remuneration has declined, explained by the company as a result of a drop in the energy generated. “The wind is still blowing the same,” he protested.

His wife, Maria José Gomes, 57, complains about the noise, even though the nearest wind turbine is about 500 meters away from their house. “Sometimes I can only fall asleep in the wee hours of the morning with the window tightly closed,” she said.

The couple lives on their share of a 265-hectare property, inherited and divided between the widow and 17 children of the previous owner, on one of the mountains of the Seridó range, part of Santa Luzia.

The 18 family members split the income from four wind towers installed on their land.

Not everyone is unhappy

On the other hand, Pedro’s brother Severino Olegario, 50, has a positive view of the Canoas Wind Farm, which also belongs to Neoenergia. The 2019 construction made it possible for him to open a restaurant to feed 40 technicians of the company who installed the mechanical components.

On the horizon can be seen one of the hills of the Borborema Plateua, whose occupation by wind turbines faces resistance from the Women’s Movement, which began holding annual marches for agroecology and in defense of the land in 2010. Nearly 5,000 women mobilized this year in opposition to wind farms in the Northeast region of Brazil. CREDIT: Mario Osava / IPS

“I sleep despite the noise and the remuneration is low because we had to divide it among a very large family,” he said. He also improved the road, which brings tourists to his restaurant on Sundays, after the construction work ended, and slowed the local exodus of people from the region.

About 1,000 families used to live in the three communities up in the mountains, due to the high level of production of cotton. But the cotton boll weevil (Anthonomus grandis) plague in the 1990s destroyed the crop and the value of the land.

“Today there are less than a hundred families left,” said Severino, who continues to grow some of the food that he uses to serve meals at his restaurant.

His perspective differs from the picture described by Oliveira to IPS by telephone from her rural community, Sobradinho, in Caetés, the result of a wind farm authorized before the government’s Brazilian Environmental Institute issued new rules in 2014.

The state government’s wind map points out mountain ranges favorable for wind energy. In red are the areas of greatest potential. The longest is the Seridó mountain range, to the west, already covered by dozens of wind farms. About 100 kilometers to the east, the second largest area, Borborema, has a women’s movement that aims to keep it free of wind farms. CREDIT: Government of Paraíba

Damage and unfavorable contracts

“There are cases of allergies that we believe are caused by the dust from the wind turbine blades, which also contaminates the water we drink, as it falls on our roofs where we collect rainwater in tanks,” Oliveira complained.

The alternative would be to buy water from tanker trucks which “costs 300 reais (62 dollars ) – too expensive for a family with two children who only harvest beans and corn once a year,” she explained, adding that growing vegetables and medicinal herbs is impossible because of the polluted water.

In addition to the audible sound, vibrations, infrasound (considered inaudible), shadow flicker (the effect of rotating turbine blades causing varying brightness levels and blocking the sun’s rays) and microparticles cause symptoms of “wind turbine syndrome,” according to Wanessa Gomes, a professor at the public University of Pernambuco, who is researching the subject with colleagues from the Oswaldo Cruz Foundation, Brazil’s leading academic public health institution.

Local families have also been living in fear since a blade broke and fell with a loud bang. Many take medication for sleep and mental illness, according to Oliveira, whose testimony aims to alert other communities to the risks posed by wind energy enterprises.

On Mar. 16, she took her complaints to the Women’s March for Life and Agroecology, organized by the Polo de Borborema in Montadas, a municipality of 5,800 people, about 280 kilometers north of Caetés.

The Polo is a group of rural workers’ unions in 13 municipalities in the Borborema highlands in the state of Paraíba, whose windy mountains are coveted by companies.

The women’s movement, with the support of the non-governmental Consultancy and Services for Alternative Agriculture Projects, mobilized 5,000 women this year, in its fourteenth edition, the second one focused on opposition to wind farms.

“Our struggle is to prevent these parks from being installed here. If many families refuse to sign the contracts with the companies, there will be no parks,” Marizelda Duarte da Silva, 50, vice-president of the Rural Workers Union of Esperança, a municipality of 31,000 inhabitants in the center of Borborema territory, told IPS.

“The contracts are draconian, up to 49 years and renewable by unilateral decision of the company,” said Claudionor Vital Pereira, a lawyer for the Polo union. “They demand unjustifiable confidentiality, charge fines for withdrawing and make variable payments for the lease depending on the amount and prices of energy generated, imposing on the lessor a risk that should only be assumed by the company.”

Water Harvesting Boosts Agriculture in Brazil’s Semiarid Northeast — Global Issues

Eronildes da Silva proudly stands next to a bunch of bananas on his farm, whose large size is the result, he says, of the effective fertilizer of reusing waste water. In addition to farming, he drives a school bus and builds rainwater tanks in Afogados da Ingazeira, in Brazil’s semiarid Northeast region. CREDIT: Mario Osava/IPS

“The rainwater tanks are the best invention in the world for us,” said Maria de Lourdes Feitosa, 46, who recalls the deadly droughts of the past in Brazil’s semiarid Northeast region.

“There has been a reduction of many diseases” that came from the so-called “barreros”, puddles and small ponds that are the result of the accumulation of water in muddy holes in the ground that people shared with animals, Feitosa, a farmer from a rural community in Afogados da Ingazeira, a municipality of 38,000 inhabitants, told IPS.

Feitosa owns a six-hectare farm and is less dependent on water than some of her neighbors because she produces agroecological cotton, which requires less water than horticultural and fruit crops.

Nearly 1.2 million tanks that collect 16,000 liters of potable rainwater from the roofs of homes now form part of the rural landscape of the semiarid ecoregion, an area that covers 1.1 million square kilometers and is home to 28 million of Brazil’s 214 million people, which extends throughout the interior of the Northeast and into the northern fringe of Brazil’s Southeast region.

The water tanks are a symbol of the transformation that the Northeast, the country’s poorest region, has been undergoing since the beginning of this century. During the longest drought in its history, from 2011 to 2018, there was no repeat of previous tragedies of deaths, mass exodus of people to the south and the looting of businesses by desperate people, as seen in the 1980s and 1990s.

According to the Articulação Semiárido Brasileiro (ASA), a network of 3,000 social organizations that created the program, adopted as public policy by the government in 2003, some 350,000 families are still in need of water tanks.

Another battle is to increase fourfold the more than 200,000 “technologies” for collecting water for production, or “second water”, which already benefit family farming and are decisive for food security and poverty reduction in the region.

Reusing household water

Josaida Nunes da Silva, 38, and her husband Eronildes da Silva, 41, resort to reusing water from the bathroom and kitchen in their home, faced with shortages aggravated by the altitude of the hill they live on in Carnaiba, a municipality of 20,000 people bordering Afogados da Ingazeira.

A complex of pipes carries the wastewater to the so-called “fat box” and then to the Upflow Anaerobic Sludge Blanket (UASB) reactor and a tank for “polishing”, exposed to the sun, and another for the water ready for irrigation.

This system filters contaminating components, such as fecal coliforms (bacteria), and prepares the water with fertilizers for irrigation of the fields and fruit trees. “We grow lettuce, onions, cilantro and other vegetables, as well as bananas, corn, cassava, papaya, guava, passion fruit and even dragon fruit,” said Nunes.

Dragon fruit comes from the cactus family, of Mexican and Central American origin, and has recently become popular in Brazil.

The large size of the banana bunch is “proof” of the fertilizer’s effectiveness, said Nunes’ husband, who adds cow dung. “The treated water is a blessing. Besides providing us with water, it gives us good fertilizer,” Nunes said.

A “stone tank” that takes advantage of holes in the rocks to store rainwater is one of the technologies used to coexist with the scarcity of rainfall in Brazil’s semiarid Northeast ecoregion.

Her husband Silva is also a bricklayer and has built many water tanks in the region. He also drives school children from the rural area in an old van and keeps fodder for his ten cows in hermetically sealed plastic bags.

“The drought hit us hard. We had to bring water from the ‘barrero’ on the plain, up the mountain in the ox cart. We bought a cow, when she was still a calf, for 2500 reais and had to sell it for 500 reais (104 dollars),” lamented his wife.

The couple owns 8.5 hectares of land, a large property in the region where most farms are only a few hectares in size, the result of the frequent divisions between heirs of the large families of the past. But since the terrain is mountainous and rocky, the cultivable area is limited.

Nunes and Silva have three children, although only the youngest, 17, still lives with them.

Coexisting with semiarid conditions

The techniques that benefit family farmers so that they can “coexist with the semiarid conditions” and prosper have been disseminated in the municipalities of the Sertão de Pajeú by Diaconia, a social organization of Protestant churches.

Pajeú is the name of the river that crosses 17 municipalities, whose basin is home to 360,000 people. The mountains surrounding the territory include the headwaters of several streams and creeks, which dry up in the dry season, but ensure greater humidity compared to other areas of the semiarid Northeast.

Agroecology practices are one of the focuses of Diaconia, whose agricultural technician Adilson Viana has dedicated 20 of his 49 years to supporting farmers and who accompanied IPS on visits to families involved in the program.

The rainwater falls on a concrete terrace on the ground that is about 200 square meters in size and is slightly inclined to fill the water tank. Braz uses it to dry and thresh string beans, which are typical of the Northeastern diet.

The couple grows fruit trees that Ramos uses to make pulp using mango, guava, acerola cherry (Malpighia emarginata) and a fruit native to the semiarid region, the umbu or Brazil plum (Spondias tuberosa), that comes from a small tree native to Northeast Brazil.

Ramos is taking a break from the activity “because it is not fruit season in the region and the energy to run the refrigerator is very expensive.” Another difficulty is that the city government’s payments for the pulp supplied to the schools have been delayed. “I only received a payment in November for sales from early last year,” she complained.

To boost the production of grains, such as beans and corn, as well as cassava, Braz grows them on his father’s four-hectare farm, about six kilometers from his own farm.

Agroecological productivity

An exceptional case of entrepreneurial vocation and availability of water is that of Ivan Lopes, 43, who together with his brother grows fruit, including bananas, pineapple, mango, grapes, avocado, passion fruit and many more, on nine hectares of land.

Water is pumped from a lagoon on the property to four reservoirs located at the higher elevations, which make gravity irrigation possible. That is why electricity is one of the farm’s biggest expenses. “I plan to install a solar power plant to save money,” Lopes told IPS.

Honey is another product they make. “The last harvest totaled 40 liters,” from dozens of hives distributed throughout the orchard. Sugarcane is grown for the sale of sugarcane juice in the cities.

The farm is also a kind of laboratory for the dissemination of organic tomato cultivation in greenhouses. “At the agroecological market in São José do Egito (a neighboring city of 34,000 people) people line up to buy my tomatoes, because they are known to be clean, pest-free and tasty,” Lopes said.

Based on their experience, there are now 10 projects for tomato production in the Pajeú Agroecological Association.

To achieve his high level of productivity, the farmer makes his own fertilizer from earthworm humus. The success he has experienced in farming prompted him to get rid of his 10 cows in order to focus on crops and beekeeping.

Biodigesters Boost Family Farming in Brazil — Global Issues

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 (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.

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.

A 1904 Massacre Could Help Save the Future of Indigenous Peoples in Brazil — Global Issues

Indigenous representatives like Raoni Metuktire, an internationally recognized Kaiapó leader, followed the Supreme Court trial on the temporary framework, inside and outside of the courtroom in Brasilia, in a case that will determine whether the land rights of the indigenous peoples of Brazil have extreme limits established by the constitution.

  • Inter Press Service

RIO DE JANEIRO, Jun 09 (IPS) – Children were thrown into the air and stabbed and cut with knives and machetes. The attackers first opened fire on the victims of the massacre before finishing them off with knives so that none of the 244 indigenous people of the village would survive. The 1904 massacre permanently marked the Xokleng people and may play a decisive role in the future of the native peoples of Brazil.

The tragedy is emblematic of the genocide suffered by indigenous people in Brazilian history. There were more numerous and recent killings, especially during the 1964-1985 military dictatorship. But the 1904 massacre is at the center of a trial in the Supreme Court that will determine the progress of the demarcation of indigenous territories in this South American country.

The trial was triggered by a move by the government of the southern state of Santa Catarina. In 2016 the state’s Institute of the Environment (IMA) lay claim to part of the demarcated land of the Xokleng people for a biological reserve.

But in 2019 the Supreme Court recognized that the case had national repercussions, setting a precedent for all demarcations of indigenous lands, because the IMA’s claim cites something that is called the “temporary framework”.

This framework states that native peoples only have the right to the lands that they physically occupied when the current constitution was promulgated on Oct. 5, 1988, creating the present system of demarcation of indigenous reserves.

The trial began in 2021, with the votes of two of the 11 Supreme Court justices, one against and the other in favor of the temporary framework. It was then suspended due to Judge Alexandre de Moraes’ request for more time to analyze the issue. It was not resumed until last month, on May 7, when Moraes issued his vote and argument, before it was suspended again on Jun. 7.

The 1904 massacre was part of his argument against the framework, as an example of the violence used to dispossess indigenous peoples of their land, which showed that it would be “unjust” to demand their physical presence on their traditional lands on any precise date. The Xokleng were “forced to leave their land in order to survive,” the judge argued.

Judge Alexandre de Moraes (C), of Brazil’s Supreme Court, is the shining star of the country’s judiciary. He issued a vote that could be decisive for the future of indigenous peoples’ lands. He also presides over the Electoral Court and is conducting investigations that could sentence former President Jair Bolsonaro to ineligibility for political office or to jail for spreading disinformation and acting against democracy.

Violence

The Ibirama-Laklãnõ Indigenous Land, where 2,300 people live today, almost all of them from the Xokleng community along with a few Guarani and Kaingang families, was demarcated in 2003: 37,000 hectares recognized as their territory by the government of Santa Catarina in 1926, according to official documents in possession of the native residents of that land.

But in 1965 the military dictatorship limited their territory to just 14,000 hectares. In addition, 10 years later, it ordered the construction of dams in the Itajaí river basin, which crosses the region, to curb flooding in cities and landed estates downstream.

Consequently, it flooded the Xokleng lands and further reduced the area where the indigenous people live and farm, as well as cutting off their roads, aggravating their isolation. An anthropological study conducted in the 1990s recommended that the territory should be expanded to the previous 37,000 hectares, but this was called into question by the local government and by landowners who had invaded part of the land.

Public attention was drawn to the near extermination of the Xokleng people by a book by anthropologist Silvio Coelho dos Santos, “Indigenous people and whites in southern Brazil: the dramatic experience of the Xokleng” ((Indios e brancos no Sul do Brasil: a dramática experiencia dos xokleng, in Portuguese), which includes a report of the 1904 massacre in the newspaper “Novidades”.

Many similar atrocities have been committed in Brazil. But the fact that this massacre in particular was well-documented and proven undermines the temporary framework, defended by many politicians and landowners and used in their legal arguments and in their attempts to reduce conflicts over land.

But it clearly runs counter to the constitution, according to Marcio Santilli, former chair of the governmental National Foundation for Indigenous Peoples (Funai) and founder of the non-governmental Socio-Environmental Institute.

“The basic unconstitutionality is that the articles (on indigenous people) do not address the temporary framework and recognize indigenous territorial rights as ‘original’. According to the constitution, there is no indigenous person without land,” he told IPS.

Thanks to the constitution’s mandate, 496 indigenous reserves, covering 13 percent of the national territory, have been demarcated so far, without taking into account the temporary framework that is now being cited.

And another 238 reserves are in different phases of the demarcation process. Some have already been identified as indigenous lands, while others are still under study, according to the Socio-Environmental Institute, which has a large database on the subject.

In Brazil, according to the 2022 census, there are 1.65 million indigenous people, an increase of 84 percent compared to the 2010 census, although they represent only 0.8 percent of the national population. In this country there are 305 distinct indigenous peoples who speak 174 languages, according to Funai.

Moraes condemned the temporary framework, but his vote worried indigenous leaders because he proposed “full compensation” to “good faith” landowners currently occupying demarcated areas. Until now, only improvements made on property have been compensated and not the land itself, which is considered to have been usurped.

Indigenous people from the metropolitan region of São Paulo block a highway with bonfires, in protest against the temporary framework, which drastically limits the demarcation of territories of native communities. Legislators are trying to give the measure legal status, while the Supreme Court postponed a ruling on the issue for the second time, on Jun. 7. CREDIT: Rovena Rosa/Agência Brasil

Reconciliation rejected

“Moraes wants prior compensation, to pay the landowners first and then demarcate the indigenous land, which can take 10 years. They are looking for a broad compromise to satisfy those who have illegally taken over land,” protested Mauricio Terena, legal coordinator of the Articulation of Indigenous Peoples of Brazil (Apib).

“Why is it always our rights that have to be chipped away at? Our rights are always compromised, we’re always the ones who lose out,” he said while speaking to the indigenous people present in Brasilia to follow the Supreme Court trial.

Nearly 1,500 indigenous people from all over the country camped out in the capital and there were demonstrations against the temporary framework in dozens of cities and towns and along highways in the country, reported Dinamam Tuxá, executive coordinator of Apib.

Moraes also proposed that, in the event of practically insurmountable difficulties, such as the existence of towns in areas recognized as indigenous land, compensation should be offered – in other words, they should be given land in other areas, if accepted by the indigenous community.

“Our territories are non-negotiable,” Terena said. “Our relationship with them runs deep, it is where our ancestors fell.”

His complaint was also due to the new interruption of the trial. Another judge, André Mendonça, a former justice minister in the far-right government of Jair Bolsonaro (2019-2022), asked for more time to study the case. He has up to 90 days to issue his vote, which would reactivate the trial, but he promised to do it sooner.

“They need time. We left here without an answer,” Terena complained. The process has been dragging on for more than seven years and the temporary framework serves as a justification for invasions of land and violence against indigenous people.

In any case, “Moraes’s vote was positive” because it recognized the unconstitutionality of the temporary framework, said Megaron Txucarramãe, chief of the Kaiapó people, who live in the Eastern Amazon region.

“We will return to Brasilia when the trial resumes, we will continue the fight to secure our constitutional rights and the land for our grandchildren,” he told IPS by phone from the indigenous camp in Brasilia.

“We will return to Brasilia to hold demonstrations whenever necessary to defend our lands, the constitution and the rights of our grandchildren,” Chief Megaron Txucarramãe, a well-known leader of the Kayapó indigenous people from the Eastern Amazon region, told IPS from the indigenous camp set up near the Supreme Court.

Lawmakers against indigenous people

But their battle is not limited to the judicial front. On May 30 the Chamber of Deputies urgently passed a bill that would make the temporary framework law, by a majority of 283 votes against 155. Its final approval now depends on the Senate.

“The processes are moving ahead simultaneously and influence each other,” Oscar Vilhena, director of the Law School at the private Getulio Vargas Foundation, told IPS from São Paulo. “If the Supreme Court declares the temporary framework unconstitutional, the bill loses its purpose, but that would increase the costs for the Supreme Court.”

By costs he was referring to increased political pressure from right-wing and landowner-linked legislators, known as the ruralists, who have long attacked the Supreme Court for allegedly meddling in legislative affairs.

In addition, if the proposed rule is declared unconstitutional, “the Chamber of Deputies could resume deliberations on a constitutional amendment already approved in the Senate,” Santilli warned by telephone from Brasilia.

This bill, which has languished in the lower house since 2015, when it was received from the Senate, would precisely establish the payment of compensation for land ownership, not only for improvements to property, to landowners affected by indigenous territories demarcated since the current constitution went into effect in October 1988.

Livestock Producers Seek to Integrate Biogas and Animal Protein Market in Brazil — Global Issues

The Toledo Bioenergy Center, in southern Brazil, is under construction, but its biodigesters are already operating with manure and the carcasses of disease-free dead animals from 16 pig farms. The goal is to generate one megawatt of power and for pig farmers to participate in the production of biogas without having to invest in their own plants, so their waste is biodigested and turned into fertilizer, instead of polluting rivers and the soil.

TOLEDO, Brazil, May 08 (IPS) – It is the “best energy,” according to its producers, but biogas from livestock waste still lacks an organized market that would allow it to take off and realize its potential in Brazil, the world’s largest meat exporter.

“There is a lack of steady consumers,” said Cícero Bley Junior, who has been a pioneer in the promotion of biogas in the west of the southern state of Paraná, since he served as superintendent of Renewable Energies at Itaipu Binacional (2004-2016).

Itaipu, a gigantic hydroelectric plant shared by Brazil and Paraguay on the Paraná River which forms part of the border between the two countries, encourages nearby pig farmers to take advantage of manure to produce biogas, avoiding its disposal in the rivers that flow into the reservoir, whose contamination affects electricity generation in the long run.

The companies that form part of the animal protein chain, in general the meat industry that purchases animals ready for slaughter and offers breeding sows and technical assistance to livestock producers, should also buy biogas and its biomethane derivative from the breeders, Bley said.

“The animal protein chain must also see itself as a generator of energy, just as the sugarcane sector defines itself as a sugar and energy industry since it began producing ethanol (a biogas) almost 50 years ago,” he told IPS.

But the companies do not do so: none of them are affiliated with the Brazilian Biogas Association (Abiogás), he lamented. The dairy industry could greatly reduce the cost of picking up milk from farms if it replaced diesel with biomethane in its trucks, he said, to illustrate.

If no such decision is taken, there will be no large investments in gas-fired engines either, which can use natural gas or biomethane, also called renewable natural gas.

In addition to the environmental benefits, such as the reduction in water pollution and the decarbonization of energy, biogas offers economic advantages by making use of manure that was previously considered waste and converting it into biofertilizer.

It also drives a new equipment industry and local development by decentralizing energy and fertilizer production.

“It’s the best energy, for sure,” said Anelio Thomazzoni, a pig farmer from Vargeão, a small municipality of 3,500 inhabitants in the west of the state of Santa Catarina in southern Brazil. His farm has a 600-kilowatt biogas power plant and a 1-megawatt solar power plant.

“The correct use of crop waste, as fertilizer after biodigestion, made it possible for me to reduce by 100 percent the purchase of potassium chloride and phosphorus,” formerly essential fertilizers, he told IPS by phone from his town.

The complexity of biodigestion, compared to photovoltaic solar energy, is a factor that is slowing down the expected progress of biogas in Brazil, despite its multiple benefits in energy, environmental and economic terms.

Frustrated potential

Brazil today produces only 0.5 percent of the biogas that could result from agricultural, livestock and industrial waste, urban garbage and sewage, estimated Bley, who founded the International Center for Renewable Energies-Biogás (CIBiogás) in 2013.

Brazil would have the potential to replace 70 percent of the diesel it consumes if it allocated all the biogas to the production of biomethane, according to Abiogás. In terms of electricity, it could reach almost 40 percent, but today it is limited to 353 megawatts – around 0.0018 percent of the total – according to the government’s National Electric Power Agency.

In global terms, Brazil is only ninth in biogas electricity generation, accounting for 2.1 percent of the global total, according to the International Renewable Energy Agency (IRENA).

The sugarcane sector joined the effort five years ago in promoting biogas, with larger plants for power generation or biomethane refining in the southern state of São Paulo. New initiatives are attempting to accelerate the development of this energy market in the southern region of Brazil, which concentrates two-thirds of the national production of pork.

Residues from the production of sugar and ethanol from cane represent 48 percent of Brazil’s biogas potential, followed by the animal protein chain, which accounts for 32.2 percent, estimates Abiogás. The rest comes from agricultural waste and sewage.

Innovative initiatives

The Bioenergy Plant under construction by CIBiogás, a nonprofit technology and innovation institution in Toledo, a city of 156,000 people in western Paraná, seeks to “validate a possible business model,” explained Juliana Somer, a construction engineer who is operations manager at the Center.

Pig farmers provide the “substrate” and receive back a part of the “digestate”, as the manure converted into a better fertilizer is called, without the gases that make up the biogas, extracted in the biodigestion process. With that they fertilize their land.

To generate electricity, biogas must have at least 55 percent methane. Carbon dioxide (CO2) is another component, making up about 40 percent. Hydrogen sulfide must be removed to prevent corrosion of the equipment.

“The objectives are environmental, social, energy-related and the dissemination of technologies,” said Rafael Niclevicz, environmental engineer at CIBiogás. To that end, an area of ??high pig farm density was chosen, with about 120,000 hogs in five square kilometers.

The manure is collected daily, 70 percent by trucks and the pig farmers themselves, and the rest by pipelines from the nearest farms. Currently, 16 pig farmers, whose herds total about 40,000 animals, supply the plant, which also collects carcasses of disease-free dead pigs.

“The model makes sense for pig farmers who do not want to invest in facilities to produce biogas on their own. It solves the problem of waste disposal and there are socio-environmental benefits for everyone,” said Somer.

This Enerdimbo truck is powered by biomethane and is used to collect manure from 40 pig producers that feeds the company’s large biodigesters in southern Brazil.

The plant is a joint project between the municipal government, which ceded the land, and Itaipu Binacional, which provided funding. The goal is an installed capacity of one megawatt.

In Ouro Verde, 22 kilometers from Toledo, a similar plant, Enerdinbo, receives the “substrate” from 40 farms within a radius of 15 kilometers, where more than 100,000 pigs are raised, for a total generation capacity of two megawatts, to which are added 500 kilowatts from a solar plant.

It is enough to provide electricity to 5,000 households, estimates EDB Energía do Brasil, the company that offers businesses and residential consumers the possibility of reducing their electricity bills by 10 percent by joining the cooperative that benefits from the electricity generated by Enerdinbo.

The business of EDB, created by businesspeople in Cascavel, 60 kilometers from Ouro Verde, is to implement small renewable energy plants to distribute the benefits of distributed generation among members of the cooperative, with the investment by the consumers themselves to save on energy costs.

Enerdinbo and the Toledo Bioenergy Plant seek to expand biogas by avoiding the difficulty for pig farmers and other small farmers or ranchers to invest in the energy business.

Demand from animal protein producers

“Small and medium-sized rural producers are true heroes who face various risks when deciding, in isolation, to implement a waste treatment project generated in the animal protein chain for the production of biogas on their properties,” said a manifesto from the producers and bioenergy specialists.

The document, released at the South Brazilian Biogas and Biomethane Forum on Apr. 18 in Foz do Iguaçu, in the far west of Paraná, calls for greater support from the public sector and from companies that link biogas production and the meat industry, for their “strategic value for Brazil’s energy transition.”

Only 333 animal waste biogas plants are suppliers to the national electricity grid, that is, 0.005 percent of Brazil’s 6.5 million livestock farms, the document stressed.

Roraima in Search of Safe and Sustainable Energy Autonomy — Global Issues

  • by Mario Osava (boa vista, brazil)

BOA VISTA, Brazil, Feb 06 (IPS) – Roraima, the northernmost state of Brazil, on the border with Guyana and Venezuela, is undergoing an energy transition that points to the dilemmas and possible solutions for a safe and sustainable supply of electricity in the Amazon rainforest.

As the only state outside the national grid – the National Interconnected Electric System (SIN) – it is dependent on diesel and natural gas thermoelectric plants, which are expensive and polluting sources, that account for 79 percent of Roraima’s electric power.

The financial and environmental cost is exacerbated by the transportation of fossil fuels by truck from Manaus, the capital of the neighboring state of Amazonas, 780 kilometers from Boa Vista, the capital of Roraima.

But the people of Roraima pay one of the lowest prices for electricity in Brazil, thanks to a subsidy paid by consumers in the rest of the country.

These subsidies will cost about 2.3 billion dollars in 2023, benefiting three million people in this country of 214 million people, according to the National Electric Energy Agency regulator.

A fifth of the total goes to Roraima, which from 2001 to 2019 received electricity imported from Venezuela. This meant the state needed less subsidies while it enjoyed a degree of energy security, undermined in recent years by the deterioration of the supplier, the Guri hydroelectric plant, which stopped providing the state with energy two years before the end of the contract.

Fortunately, Roraima has natural gas from deposits in the Amazon, extracted in Silves, 200 kilometers from Manaus, to supply the Jaguatirica II thermoelectric power plant, inaugurated in February 2022, with a capacity of 141 megawatts, two thirds of the state’s demand.

Roraima thus reduced its dependence on diesel, which is more costly and more polluting.

But what several local initiatives are seeking is to replace fossil fuels with clean sources, such as solar, wind and biomass.

This is the path to sustainable energy security, says Ciro Campos, one of the heads of the Roraima Renewable Energy Forum, as a representative of the Socio-Environmental Institute (ISA), a pro-indigenous and environmental non-governmental organization.

The city government in Boa Vista, the state capital, home to two thirds of the population of Roraima, has made progress towards that goal. Solar panels cover the roofs of the city government building, municipal markets and a bus terminal, and form roofs over the parking lots of the municipal theater and the Secretariat of Public Services and the Environment.

In addition, a plant with 15,000 solar panels with the capacity to generate 5,000 kilowatts, the limit for so-called distributed generation in Brazil, was built on the outskirts of the city.

In total there are seven plants with a capacity to generate 6,700 kilowatts, in addition to 74 bus stops equipped with solar panels, some of which have been damaged by theft, lamented Thiago Amorim, the secretary of Public Services and the Environment.

In addition to the environmental objective, solar energy allows the municipality to save the equivalent of 960,000 dollars a year, funds that are used for social spending. Boa Vista describes itself as “the capital of early childhood” and has won national and international recognition for its programs for children.

The Renewable Energies Forum and the Roraima Indigenous Council (CIR), which promote clean sources, say the aim is to reduce the consumption of diesel, a fossil fuel transported from afar whose supply is unstable, and to avoid the construction of the Bem Querer hydroelectric plant.

The project, of which there are still no detailed studies, would dam the Branco River, Roraima’s largest water source, to form a 519-square-kilometer reservoir that would even flood part of Boa Vista. It would affect nine indigenous territories directly and others indirectly, said Edinho Macuxi, general coordinator of the CIR.

Bem Querer would have an installed capacity of 650 megawatts, three times Roraima’s total demand. It has awakened interest because it would also supply Manaus, a metropolis of 2.2 million inhabitants that lacks energy security, and could produce more electricity just as the generation of other hydroelectric plants in the Amazon region is declining.

Almost all of Roraima is in the northern hemisphere, and the rainiest season runs from April to September, when water levels run low in the rest of the Amazon region. The state’s hydroelectricity would therefore be complementary to the entire Brazilian portion of the rainforest.

That is why Bem Querer is a project inextricably connected to the construction of the transmission line between Manaus and Boa Vista, already ready to start, which would integrate Roraima with the national grid, enabling it to import or export electricity.

“We can connect, but we reject dependency, we want a safe and autonomous energy model. We will have ten years to find economically and politically viable solutions,” said Ciro Campos.

Solar Energy Useless Without Good Batteries in Brazils Amazon Jungle — Global Issues

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 (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.

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.

The Energy Dilemmas of Roraima, a Unique Part of Brazils Amazon Region — Global Issues

BOA VISTA, Brazil, Dec 21 (IPS) – “Roraima did not have a Caribbean character; now it does, because of its growing relations with Venezuela and Guyana,” said Haroldo Amoras, a professor of economics at the Federal University of this state in the extreme north of Brazil.

The oil that the U.S. company ExxonMobil discovered off the coast of Guyana since 2015 generates wealth that will cross borders and extend to Roraima, already linked to Venezuela by energy and migration issues, predicted the economist, the former secretary of planning in the local government from 2004 to 2014.

Roraima, Brazil’s northernmost state, which forms part of the Amazon rainforest, is unique for sharing a border with these two South American countries on the Caribbean Sea and because 19 percent of its 224,300 square kilometers of territory is covered by grasslands, in contrast to the image of the lush green Amazon jungle.

It is also the only one of Brazil’s 26 states not connected to the national power grid, SIN, which provides electricity shared by almost the entire country. This energy isolation means the power supply has been unstable and has caused uncertainty in the search for solutions in the face of sometimes clashing interests.

From 2001 to 2019 it relied on imported electricity from Venezuela, from the Guri hydroelectric plant, whose decline led to frequent blackouts until the suspension of the contract two years before it was scheduled to end.

The closure of this source of electricity forced the state to accelerate the operation of old and new diesel, natural gas and biomass thermoelectric power plants. It also helped fuel the proliferation of solar power plants and the debate on cleaner and less expensive alternatives.

In search of energy alternatives

Against this backdrop, the Roraima Alternative Energy Forum emerged, promoted by the non-governmental Socio-environmental Institute (ISA) and the Climate and Society Institute (ICS) and involving members of the business community, engineers from the Federal University of Roraima (UFRR) and individuals, indigenous leaders and other stakeholders.

The objectives range from influencing sectoral policies and stimulating renewable sources in the local market to monitoring government decisions for isolated systems, such as the one in Roraima, as well as proposing measures to reduce the costs and environmental damage of such systems.

“Not everyone (in the Forum) is opposed to the construction of the Bem Querer hydroelectric plant, but there is a consensus that there is a lack of information to evaluate its benefits for society and whether they justify the huge investment in the project,” biologist Ciro Campos, an ISA analyst and one of the Forum’s coordinators, told IPS.

Bem Querer, a power plant with the capacity to generate 650 megawatts, three times the demand of Roraima, is the solution advocated by the central government to guarantee a local power supply while providing the surplus to the rest of the country.

For this reason, the project is presented as inseparable from the transmission line between Manaus, capital of the state of Amazonas with a population of 2.2 million, and Boa Vista, the capital of Roraima, population 437,000. The line involves 721 kilometers of cables that would connect Roraima to the national grid.

Indigenous people in the northern Brazilian state of Roraima are striving to install solar plants in their villages and are studying how to take advantage of the winds in their territories, which are considered favorable for wind energy. Their aim is to prevent the construction of Bem Querer and other hydroelectric plants that would affect indigenous lands, according to Edinho Macuxi, coordinator of the Indigenous Council of Roraima.

“In its design, Bem Querer looks towards Manaus, not Roraima,” Campos complained, ruling out a necessary link between the power plant and the transmission line. “We could connect to the SIN, but with a safe and autonomous model, not dependent on the national system” and subject to negative effects for the environment and development, he argued.

Hydroelectric damage

The plant would dam the Branco River, the state’s main water source, to form a 519-square-kilometer reservoir, according to the governmental Energy Research Company (EPE). It would even flood part of Boa Vista, some 120 kilometers upstream.

The hydropower plant would both meet the goal of covering the state’s entire demand for electricity and abolish the use of fossil fuels, diesel and natural gas, which account for 79 percent of the energy consumed in the state, according to the distribution company, Roraima Energia.

But it would have severe environmental and social impacts. “It would make the riparian forests disappear,” which are almost unique in the extensive savannah area, locally called “lavrado,” of grasses and sparse trees, said Reinaldo Imbrozio, a forestry engineer with the National Institute of Amazonian Research (Inpa).

A view of the Branco River, five kilometers above where its waters would be dammed if the controversial Bem Querer hydroelectric plant is built, which would generate enough electricity to meet the entire demand of the Brazilian state of Roraima as well as a surplus for export, but would have environmental and social impacts magnified by the flatness of the basin that requires a very large reservoir.

In addition to the flooding of parts of Boa Vista, the flooding of the Branco and Cauamé rivers, which surround the city, will directly affect nine indigenous territories and will have an indirect impact on others, complained Edinho Macuxi, general coordinator of the Indigenous Council of Roraima (CIR), which represents 465 communities of 10 native peoples.

The CIR, together with ISA and the ICS, built two solar energy projects in the villages and carried out studies on the wind potential, already recognized in the indigenous territories of northern Roraima.

“The main objective of our initiatives is to prove to the central government that we don’t need Bem Querer or other hydroelectric projects…that represent less land and more confusion, more energy and less food for us,” he stressed to IPS at CIR headquarters.

“We will have to leave, said the engineers who were here for the studies of the river,” said Alfredo Cruz, owner of a restaurant on the banks of the Branco River, about five kilometers upstream from the site chosen for the dam. At that spot visitors can swim in the dry season, when the water level in the river is low.

Economics Professor Haroldo Amoras says the state of Roraima is becoming more Caribbean, because its economy is increasingly linked to its neighboring countries to the north of Brazil, Guyana and Venezuela, which, in addition to being importers, are the route to the Caribbean for Roraima’s agricultural and agro-industrial products.

The rapids there show the slight slope of the rocky riverbed. It is a flat river, without waterfalls, which means a larger reservoir. The heavy flow would be used to generate electricity in a run-of-river power plant.

Cruz inherited his restaurant and house from his great-grandfather. The title to the land dates back to 1912, he said. But they will be left under water if the hydroelectric plant is built, even though they are now located several meters above the normal level of the river, he lamented.

Riverside dwellers, fishermen and indigenous people will suffer the effects, Imbozio told IPS. The property of large landowners and people who own mansions will also be flooded, but they have been guaranteed good compensation, he added.

What the Forum’s Campos proposes is the promotion of renewable sources, without giving up diesel and natural gas thermoelectric plants for the time being, but reducing their share in the mix in the long term, and ruling out the Bem Querer dam, which he said is too costly and harmful.

Energy issues will influence the future of Roraima, according to Professor Amoras. The most environmentally viable hydroelectric plants, such as one suggested on the Cotingo River, in the northeast of the state, with a high water fall, including a canyon, are banned because they are located in indigenous territory, he said.

The participation of civil society is important for the Brazilian state of Roraima to make progress towards sustainable energy alternatives that can reduce diesel consumption, offer energy security and avoid the impacts of hydroelectric dams, according to Ciro Campos, an analyst with the non-governmental Socio-environmental Institute.

Oil wealth, route to the Caribbean

In the neighboring countries, oil wealth opens a market for Brazilian exports and, through their ports, access to the Caribbean. The Guyanese economy will grow 48 percent this year, according to the World Bank.

Roraima’s exports have grown significantly in recent years, although they reached just a few tens of millions of dollars last year.

Guyana’s small population of 790,000, the unpaved road connecting it to Roraima and the fact that the language there is English make doing business with Guyana difficult, but relations are expanding thanks to oil money.

This will pave the way to the Caribbean Community (CARICOM), whose scale does not attract transnational corporations, but will interest Roraima companies, said Fabio Martinez, deputy secretary of planning in the Roraima state government.

Venezuela expanded its imports from Roraima, of local products or from other parts of Brazil, because U.S. embargoes restricted trade via ports and thus favored sales across the land border, he said.

“The liberalization of trade with the United States and Colombia will now affect our exports, but a recovery of the Venezuelan economy and the rise of oil can compensate for the losses,” Martinez said.

Roraima is a new agricultural frontier in Brazil and its soybean production is growing rapidly. But “we want to export products with added value, to develop agribusiness,” said Martinez.

That will require more energy, which in Roraima is subsidized, costing consumers in the rest of Brazil two billion reais (380 million dollars) a year. If the state is connected to the national grid through the transmission line from Manaus, there will be “more availability, but electricity will become more expensive in Roraima,” he warned.
