On a Wednesday in July, deep in a coastal restinga area of Brazil’s Paraná state, muffled footsteps broke through the chirping of manakins. Three field researchers from the conservation NGO Society for Wildlife Research and Environmental Education (SPVS) moved carefully along a trail, each carrying a small cage covered in a dark cloth. Each cage held a black-faced lion tamarin, known locally as the caissara lion tamarin (Leontopithecus caissara). Captured safely from the canopy, the three small primates — two males and one female — were carried to a makeshift tent in a forest clearing, where they would make history. Within hours, they would become the first of their species to be vaccinated against yellow fever. A team of researchers and veterinarians was waiting, quickly transferring each tamarin into a cotton bag to be weighed, starting a race against the clock to protect one of Brazil’s most threatened mammals. L. caissara is one of four lion tamarin species endemic to the Atlantic Forest; it ranks among the world’s rarest primates. First found and described by science in 1990, its wild population was estimated at just 392 individuals in a 2011 study. Most tamarins are confined to coastal restinga areas along the São Paulo-Paraná state border.

The species’ already restricted range has also been fragmented for decades. Part of the problems started with the Varadouro Canal, a 6-kilometer (3.7-mile)-long, 50-meter (164-feet)-wide artificial…This article was originally published on Mongabay

SCHIPKAU, Germany (AP) — A wind turbine described by its developer as the world’s tallest now rises 365 meters (1,197 feet) above the sparsely populated landscape of eastern Germany, surpassing the height of the Eiffel Tower. The colossal turbine has been built at an existing wind farm in Lusatia, southeast of Berlin. Once a major center of lignite mining, the region has increasingly turned to renewable energy in recent years. The prototype reached its full height this week and is due to be inaugurated in mid-November. Jochen Grossmann, chief executive of Gicon, the Dresden-based engineering company that built the tower, said the structure would harness the stronger, more reliable winds found at greater heights. Conventional wind turbines typically have a hub height — the distance from the ground to the center of the rotor — of well below 200 meters (656 feet). “At 300 meters, we have such constant and strong wind that we can produce more than twice as much electrical energy as with the same facility at today’s heights,” Grossmann said on Thursday. He added that it would also be possible to produce electricity for much more of the year than with existing turbines. The turbine has a hub height of 300 meters (984 feet), and its rotor blades bring its total height to 365 meters. That makes it taller than the Eiffel Tower in Paris, at 330 meters (1,083 feet), and leaves it just short of Berlin’s television tower, Germany ‘s tallest building at 368 meters (1,207…This article was originally published on Mongabay

A new initiative between the U.S. and Argentina is meant to bolster investment opportunities and strengthen supply chains for critical minerals that could be used in the clean energy transition, such as copper and lithium. The Andes-Atlantic Corridor, announced Sept. 23, will make it easier to funnel U.S. investment into Argentina’s mining sector and to export critical minerals. At the same time, the initiative will help continue to develop the Vaca Muerta region, home to Argentina’s largest oil and gas reserves. “Working together, the United States and Argentina seek to continue to build on our robust relationship through increased U.S. investment, close security cooperation, and aligned values,” the two countries said in a joint statement. Argentina has about 117.91 million metric tons of copper reserves and 216.32 million metric tons of lithium carbonate equivalent, the chemical used in lithium-ion batteries. Many of the country’s minerals are needed for building the cables and transformers in power grids, wind turbines and solar panels, among other things. The country is also part of the “Lithium Triangle,” alongside Chile and Bolivia, an approximately 400,000-square-kilometer (154,400-square-mile) stretch of salt flats where 40-60% of the world’s lithium is located. Historically, exporting minerals has been a challenge for Argentina. The closure of a major copper mine and a lack of foreign investment, among other economic troubles in the country, saw copper exports drop between 2012 and 2019, according to an analysis by the Payne Institute for Public Policy, a U.S.-based think tank studying energy, natural resources, and…This article was originally published on Mongabay

Renewable energy companies are driving most of Brazil’s plans for new data centers, according to a recent joint analysis by The Intercept Brasil and Mongabay. As of December 2025 there were 68 requests to connect data centers to Brazil’s national power grid with 65% registered by renewable energy companies, including wind and solar power plants, the investigation found. Brazil produces more renewable energy than it can distribute across its territory, and the national power grid cannot always absorb all the power generated by renewable energy plants. Doing so would cause disruptions in provision, and potentially even blackouts. To avoid this, the national grid operator frequently orders plants to halt production. In the first half of 2025 such measures cost power generators an estimated 3.2 billion reais ($617 million). One solar plant was forced to cut production by nearly 40% in 2025. Renewable energy companies argue that data centers, which constantly demand large amounts of energy, can provide more stability and income for the renewable energy sector. The Brazilian government has been actively seeking deals with big tech companies, advertising Brazil as an environmentally friendly host for data centers. On Sept. 15, President Luiz Inácio Lula da Silva signed a law exempting data centers from several taxes on equipment purchases if they meet water efficiency criteria and use renewable or low-emission energy. In April 2026, Brazil’s foreign trade agency, Apex, organized a roundtable in the U.S. to attract foreign investment for sustainable data centers. “Renewable energy companies are able to sign…This article was originally published on Mongabay

LIBREVILLE — In the traditional-medicine corner of La Peyrie Market in Libreville, iboga comes in a repurposed clear rum bottle packed to the neck with pale bark powder, set among tinctures in old plastic bottles. Two men appeared within a minute on this day in July, and once they heard they were talking to a journalist, went half-giddy. They were happy to say where the root goes: overseas, to clinics, some of it ground into capsules. “Do the buyers pay well?” “They pay well,” one said. And all of it, he insisted, was legal. Iboga, Tabernanthe iboga, is a plant native to the wet forests of West-Central Africa. And here in Gabon, its root bark plays a central role in several Bwiti (or Bwété) traditions. It is also the original source of ibogaine, an alkaloid extracted from the root, now drawing intense interest as an experimental treatment for addiction and other mental-health conditions. The sellers at the market called the money good. But, further down the value chain, ibogaine treatment can cost thousands of dollars per patient. That gap, Gabonese practitioners and officials say, is at the heart of the dispute: the plant and the knowledge are theirs — and are threatened with overexploitation — while a lot of the money is made abroad. A 2023 Interpol analysis also found much of the trade was illicit, identifying that online resellers nearly quadrupled between 2021 and 2023. And the market for the plant may only get bigger, officials speculate. An unidentified…This article was originally published on Mongabay

Dolphins, it turns out, don’t like to mix business and pleasure. Scientists have found that the marine mammals keep their feeding and hunting areas separate from the places where they socialize with one another. A study published in the journal PeerJ details how a team of researchers listened in on dolphins living along the Atlantic coast of Florida to “provide evidence of acoustic habitat differentiation.” “They have distinct habitats that correspond to different behaviors,” Laurent Chérubin, a marine scientist at the Harbor Branch Oceanographic Institute at Florida Atlantic University, who led the study, told Mongabay in a video interview. Scientists gathered the audio data with the help of an acoustic wave glider, a 12-foot (3.7-meter) solar-powered autonomous marine vehicle. The glider was deployed for two months along the East Florida Shelf, between Fort Pierce and Jacksonville. In addition to recording 62 hours of underwater audio, the glider also carried sensors gathering environmental data such as water temperature, salinity, turbidity, and the concentration of chlorophyll-a, a pigment that plays a critical role in photosynthesis. “The glider has a bunch of sensors and can host a lot of payload,” Chérubin said. “It can be at sea on its own for as long as needed because it uses solar power and wave action to move around.” On analyzing the data, the scientists detected dolphins in more than 1,600 recordings. They then classified their calls into whistles, which dolphins use to communicate with each other, and rapid clicking sounds, which the animals use as…This article was originally published on Mongabay

  This is an abridged version of a piece I wrote shortly after her death a year today. I find it hard to believe Jane Goodall is gone. She was more than an icon to me. She was a friend, a mentor, and someone whose presence felt like both a gift and a lesson. Our friendship began in the most Jane way possible: an email that opened, “Yes, this is the real Jane Goodall,” followed by a request that I not share her “secret email address.” She said she admired Mongabay and wanted to meet. That message was the start of thirteen years of laughs, tears, and conversations that often stretched late into the night over vegan Indian food and a glass of whisky in her hotel room—even though I rarely drink or stay out late. Jane had a way of making every encounter feel personal. When she first met my children, she lit up as if she had been waiting her whole life for them to enter the room. She crouched to their level, told stories, and pulled up YouTube videos of rats performing clever tricks. “Aren’t they marvelous?” she said, with the same awe she once expressed for the chimpanzees of Gombe. She told my son he was an inspiration for starting a trash cleanup at his school.  She believed hope was not simply a feeling but a tool. Hope, she would tell me, creates agency. The larger the crisis, the more powerless people feel. But small, local…This article was originally published on Mongabay

NEW YORK — Long before Dickson Kaelo became one of the leading voices for community conservancies in Kenya, conservation was something much more personal. He grew up with livestock. His father was a veterinarian. And he knew firsthand the uneasy relationship between pastoralist communities and wildlife: Lions killing cattle, elephants destroying crops, hyenas taking goats — sometimes dozens of sheep in a single night. “That’s their (communities’) food. That’s what they sell to get fees to take their children (to school),” Kaelo, a member of Kenya’s semi-nomadic pastoralist Maasai community, told Mongabay. Fresh from college nearly three decades ago, Kaelo began wondering whether there was another way, something between conflict with wildlife and a conservation model that excluded communities from protected areas. Working with elders near the northern Maasai Mara, he helped organize a community trust (an organization created by community members to collectively manage land, resources or revenues for their shared benefit) in 1998. It built dams and dispensaries, supported hundreds of students through scholarships and experimented with generating tourism income while keeping livestock on the landscape. Then it fell apart. While Kaelo was away studying wildlife, the land under the care of the trust was subdivided into individual holdings. He considered abandoning conservation altogether. “One part of me was saying, it’s time to give up and go out to the city and do something,” he recalled. Instead, Kaelo returned to the same landscape with a belief that land could be privately owned but still managed collectively. Between 2004…This article was originally published on Mongabay

Vantara, the billionaire-run Indian private zoo that houses more than 150,000 animals, discussed a “strategic conservation partnership” with authorities in Brazil, the world’s most biodiverse country, according to documents obtained by Mongabay under Brazil’s Freedom of Information Act (FOIA). Correspondence between Vantara representatives and Brazilian officials reveal that negotiations, initiated by Vantara, began in August 2025, and involved some of Brazil’s threatened species. The zoo, which is located in Gujarat state in western India, was founded in 2025 by Anant Ambani. He’s the youngest son of India’s richest person, Mukesh Ambani, who heads Reliance Industries, a conglomerate valued at $167 billion as of press time. On Aug. 30, 2025, a Vantara representative sent a letter by email to three officials at the Chico Mendes Institute for Biodiversity Conservation (ICMBio), the governmental agency responsible for protecting Brazil’s biodiversity. The sender’s identity was redacted in the FOIA response. The subject line reads, “Proposal for Strategic Conservation Partnership with the Government of Brazil.” The letterhead uses Vantara’s official name, the Greens Zoological Rescue and Rehabilitation Centre (GZRRC). The letters are addressed to Mauro Pires, president of ICMBio; Marcelo Marcelino de Oliveira, the agency’s director; and Raul Fontoura, its head of international affairs. The letter sent by Vantara to ICMBio proposing a “strategic conservation partnership.” Obtained by Mongabay through FOIA. The letter states that Vantara was “well-positioned to assist with other Brazilian species requiring urgent ex-situ intervention,” referring to the conservation strategy of keeping a population surplus in zoos and breeding centers, rather than…This article was originally published on Mongabay

Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For much of the 20th century, Cuba’s spiders and scorpions received limited attention beyond specialist circles. Identifying them required careful research in museum collections and comparing them with descriptions published abroad. Giraldo Alayón García spent much of his career documenting Cuba’s arachnids and bringing them to the public’s attention. In San Antonio de los Baños, southwest of Havana, he used Radio Ariguanabo to discuss wildlife with a general audience. At the National Museum of Natural History of Cuba, where he spent almost four decades, he helped build one of the Caribbean’s principal collections of arachnids. At the museum, he curated specimens collected in Cuba and elsewhere in the Caribbean, and added the records that made the collection useful to other researchers. Under Alayón, the museum’s arachnological collection became one of the Caribbean’s most substantial. In 1994, he published a list of Cuba’s spiders, which became a standard point of reference for work on the island’s arachnids. Across his career, he described about 95 species and genera, most of them endemic to Cuba. He also worked abroad. From 1993 to 1995, he directed the Arachnological Project of Yucatán in Mexico. In 1999, he led an expedition to Navassa Island — contested between Haiti and the U.S. — where researchers identified several species new to science. One, the scorpion Cazierius alayoni, was named for him. Alayón first took wildlife to a wider audience on Radio…This article was originally published on Mongabay

Rising sea levels due to climate change could damage hundreds of thousands of properties and millions of hectares of land along Australia’s coastline by 2100, according to a recent study. This could cost the country an economic loss of $855 billion, researchers estimate. To calculate the costs, researchers in Australia used existing projections of sea level rise and storm surges to map out the areas that could suffer flooding by 2100. Then they identified all the houses, properties, agricultural land, and other land and infrastructure in the vulnerable areas and used real estate sources to estimate their values and arrive at what their damage could cost. The analysis showed that by 2100, under a scenario where greenhouse gas emissions remain moderate, sea level rise and storm surges could damage roughly 268,000 properties and 2 million hectares (4.9 million acres) of land in Australia. That’s a present-value economic loss of $855.1 billion. Under a high-emissions scenario, nearly 720,000 properties and 3.7 million hectares (9.1 million acres) of Australian coastal properties could suffer damage, amounting to present-value losses of up to $1.91 trillion. “Sea level rise may physically affect a large number of Australians who live near the coast, as the majority of Australians live within 50 kilometres [31 miles] of the coastline,” Tom Kompas, study lead author and a professor of environmental economics and biosecurity at the University of Melbourne, said in a statement. Australia’s coastline is massive, extending roughly 34,000 kilometers (21,000 miles). The analysis found that every region of…This article was originally published on Mongabay

At least 20 endangered Ganges river dolphins still survive in Bangladesh’s extremely polluted Buriganga River, a 12-month study found, reports contributor Md Jahidul Islam for Mongabay. Skirting the southern edge of the country’s capital, Dhaka, the 29-kilometer (18-mile) river is recognized as one of the most contaminated urban waterways globally. Researchers surveyed a 27-km (16.7-mi) stretch of the river between September 2023 and August 2024, observing Ganges river dolphins (Platanista gangetica) in 10 out of the 12 survey months. Group sizes averaged about four individuals, with calves accounting for nearly 16% of sightings, signaling active reproduction despite severe ecological degradation. “The Buriganga is not a usual place for dolphins, where native fishes have largely vanished,” study co-author and researcher Md. Aminur Rahman told Mongabay. “When we found [the dolphins], we were amazed at how it was possible. Because the river is not livable for fish.” A 2025 study on the Buriganga River’s water pollution showed that it absorbs untreated industrial effluent from tanneries, textile dyeing plants, battery factories, and municipal sewage. Levels of toxic heavy metals, including lead, chromium, and cadmium, routinely exceed World Health Organization safety limits, driving dissolved oxygen levels near zero during the dry season, the study reads. While native fish species have collapsed, pollution-tolerant invasive suckermouth catfish (Hypostomus plecostomus), native to South America, have multiplied rapidly, Rahman said. Mohammad Abdul Aziz, study co-author and zoology professor at Jahangirnagar University in Dhaka, told Mongabay that the dolphins have likely adapted their diet to survive on these invasive…This article was originally published on Mongabay

JAKARTA — In 2016, following the most devastating land and forest fires in its recorded history the previous year, the Indonesian government set up an agency to restore peatlands, among the worst-hit biomes during the disaster. A decade later, following the most devastating land and forest fires since the 2015 season, the current government has once again set up an agency to restore peatlands — prompting questions over what impact, if any, this new body will have. The National Peatland and Mangrove Management Agency, or BPGMN, was announced by Forestry Minister Raja Juli Antoni following a meeting at the State Palace in Jakarta on Sept. 24 between President Prabowo Subianto and a group of 22 experts. Like the earlier Peatland and Mangrove Restoration Agency (BRGM) established by Prabowo’s predecessor, Joko Widodo, which was shuttered in December 2024, the new agency will report directly to the president and be staffed by scientists and professionals, according to Raja Juli. For some observers, that begs the question of why Prabowo didn’t renew the BRGM’s mandate and instead let it expire, and what the BPGMN will do differently. “The BPGMN must not stop at changing the institution’s name,” said Uli Arta Siagian, national campaign coordinator for Walhi, Indonesia’s biggest environmental advocacy group. “The experience of the BRGM, which was disbanded at the end of 2024 after operating for nearly a decade, shows that changing the institutional structure does not automatically guarantee better governance. “The BPGMN must have a mandate, authority, success indicators, and working…This article was originally published on Mongabay

UMPHANG, Thailand — At 8 a.m. on June 26, at least 13 double-trailer trucks were lined up at the Pheung Khleung border crossing in northern Thailand — one of the few places where minerals can be legally transported overland from Myanmar into Thailand. Tensions were running high under the sun. The border gate had not yet opened and irate mineral merchants were yelling at reporters, demanding that no photos be taken. The previous day, the Thai military personnel that oversee the cross-border mineral trade had granted Mongabay permission to document the hundreds of tons of antimony expected to be delivered from Myanmar’s Karen state to Thailand’s Tak province, some 200 kilometers (124 miles) south of the city of Mae Sot. Reporters were forbidden from photographing soldiers’ involvement in the trade or the minerals themselves. It wasn’t until 10 a.m. that the border gates opened and the first truck from Karen state bearing antimony, a silvery mineral used in bullets, bombs, armor, semi-conductors and other defense, aerospace and tech industries, crossed into Thai territory. Bars of processed antimony were hoisted from Myanmar trucks into Thai trucks at the Pheung Khleung border crossing in June 2026. Image by Gerald Flynn / Mongabay. A crane, followed by a parade of battered trucks, rolled over from Myanmar and instantly workers from both sides frantically began attaching hoisting cables to 1-ton bags of what reporters were told was antimony ore and stacked bars of antimony ingot.

With illegal logging and agricultural expansion closing in on their lands, four Indigenous Wounaan and Emberá-Wounaan villages in Panama’s Darién forest started a biodiversity monitoring project to document their forests’ conservation status, reports Mongabay contributor María Paula Rubiano A. Their biodiversity monitoring project recorded more than 200 species across 18,000 hectares (44,500 acres) of threatened forest, including three “umbrella” species: Jaguars (Panthera onca), Baird’s tapirs (Tapirus bairdii) and crested eagles (Morphnus guianensis). At least 15 of the species they documented are classified as threatened. The communities are now using the data as a baseline for joining the biodiversity credit market, which they hope can generate revenue in an area where there are few opportunities to earn money. The communities are using bioacoustic monitoring and camera-trapping with the support of the Panama-based NGO FSC Indigenous Foundation and Health In Harmony, an international nonprofit. They are employing a methodology developed by Savimbo, a biodiversity credit company co-founded by Indigenous community members, that uses 15 indicator species as a proxy for forest health. Samuel Cheucarama, who lives in an Indigenous Wounaan village, told Rubiano the efforts have already changed behavior in the communities. “People don’t go hunting anymore. They’re saying, ‘We’re going to put up a ‘No Hunting’ sign.” Read the full article here.
