The Latest News on Rainforests
Endangered seabirds return to Pacific island after century-long absence (Dec 14 2024)
- Endangered Polynesian storm petrels have returned to Kamaka Island in French Polynesia for the first time in more than 100 years, after conservationists used drones to remove the invasive rats eating the birds’ eggs and chicks.
- Scientists attracted the birds back to the island using solar-powered speakers playing bird calls recorded from a neighboring island, with monitoring cameras showing regular visits, though nesting has not yet been confirmed.
- The project demonstrates successful collaboration between international conservation groups and local communities, with the local Mangareva community’s knowledge and support proving crucial to the operation’s success.
- The birds’ return could benefit the entire island ecosystem, as seabirds bring nutrients from the ocean that help sustain both terrestrial and marine life around the island.
Study looks for success factors in African projects that heal land and help people (Dec 13 2024)
- Land degradation across Africa impacts the lives of rural Africans, who depend heavily on natural resources.
- Reversing land degradation while improving livelihoods can be tricky, and not all initiatives succeed.
- A recent Sustainability Science study examined 17 initiatives in 13 African nations to tease out what factors contribute to success or failure.
- The study finds that tapping into social relationships, providing adequate incentives to overcome risk-adverse behaviors, and maintaining momentum over the long term emerged as key factors in an initiative’s success.
Illegal cockfighting threatens endangered sea turtles across Central America (Dec 13 2024)
- The hawksbill sea turtle (Eretmochelys imbricata), a critically endangered species, has long been exploited for its shell, used in a wide range of ornaments, including, in Costa Rica, the deadly spurs used in illegal cockfighting.
- Cockfighting is banned in Costa Rica, but the tradition persists underground, with authorities increasing their efforts to seize hawksbill spurs.
- Conservationists are also helping to train inspection officers to identify hawksbill products brought into Costa Rica from neighboring countries.
- When poachers harvest hawksbills, they’re not targeting them specifically for spurs but also for other products, which often find their way into tourist shops and online markets worldwide.
Direct air capture climate solution faces harsh criticism, steep challenges (Dec 13 2024)
- Direct air capture — geoengineering technology that draws carbon dioxide from the air, allowing it to be stored in geologic formations or used by industry — is being heavily hyped as a climate solution.
- But as direct air capture (DAC) pilot projects an startups grow in number around the world, fueled by investment and government funding in the U.S. and elsewhere, this proposed climate solution is becoming ever more divisive.
- Critics paint DAC as a costly, ineffective distraction from drastically slashing fossil fuel extraction and emissions. The use of captured carbon by the fossil fuel industry to squeeze ever more oil from wells comes in for particularly sharp criticism.
- Though carbon dioxide removal (CDR) may be needed to help limit the worst impacts of global warming, experts say betting on direct air capture is riddled with challenges of cost and scale. Two hurdles: sourcing sufficient renewables to power DAC facilities, and minimizing carbon-intensive DAC infrastructure.
Recycling gold can tackle illegal mining in the Amazon, but is no silver bullet (Dec 13 2024)
- Artisanal and small-scale gold mining in Brazil’s Tapajós River Basin emits 16 metric tons of CO2 per kilo of gold produced, and 2.5 metric tons of mercury annually, a study has found.
- Researchers suggest that recycling gold could dramatically reduce harmful emissions, along with other solutions such as formalizing mining, adopting clean technologies, and improving gold supply chain transparency.
- Economic dependence, mercury accessibility, and a demand for gold sustain small-scale gold mining, while enforcement risks pushing miners into ecologically sensitive areas.
- In November, Brazil launched a federal operation in the Tapajós Basin to expel illegal gold miners from the Munduruku Indigenous Territory, imposing millions of reais in fines to curb the damage caused by gold mining.
Climate change fuels African floods that hit harder in vulnerable regions (Dec 13 2024)
- Extreme rainfall and flooding across Sudan, Cameroon, Niger, Nigeria and Chad this year led to thousands of deaths and millions of displacements, mirroring what occurred in the region in 2022.
- Research by World Weather Attribution shows that such extreme floods, linked to anthropogenic climate change, are likely to become more intense and frequent in the future.
- Existing conflicts, poverty, aging infrastructure and socioeconomic inequalities further exacerbate the exposure of vulnerable communities to extreme floods; local leaders and experts call for improved sanitation and urban development policies as well as adaptation strategies in preparation for future floods.
Vietnam’s mammals need conservation within and outside their range: Study (Dec 13 2024)
- Vietnam is a treasure trove of mammalian diversity: it’s home to the highest number of primate species in mainland Southeast Asia and a host of unique species found nowhere else on the planet.
- However, a new study reveals more than one-third of Vietnam’s mammal species are threatened with extinction at a national level.
- The researchers advocate combining field-based and ex-situ conservation measures to recover the country’s mammal populations.
- They recommend conservation managers focus on establishing captive-breeding populations of key conservation species, as well as strengthening protection of habitats and creating wildlife corridors.
Foreign investor lawsuits impede Honduras human rights & environment protections (Dec 12 2024)
- Foreign investors in Honduras have “extraordinary privileges,” allowing them to sue the government for reforms that affect their investments, hindering public interest legislation, a recent report has found.
- Honduras faces billions of dollars in lawsuits from corporations, many tied to controversial investments made after the 2009 coup, creating a deterrent effect on the government’s ability to make sovereign decisions and making it the second-most-sued country in Latin America over the period of 2023 to August 2024, after Mexico.
- Some local communities in Honduras are divided over foreign investment projects, with several expressing resistance due to concerns about their impact on the environment and land rights.
- Honduras’ recent energy reforms and mining bans are facing backlash and legal challenges, as foreign corporations resist changes aimed at protecting natural resources and human rights.
Indonesian forests put at risk by South Korean and Japanese biomass subsidies (Dec 12 2024)
- Subsidies for forest biomass energy in Japan and South Korea are contributing to deforestation in Southeast Asia, according to an October 2024 report by environmental NGOs. The biomass industry is expanding especially quickly in Indonesia; the nation is exporting rapidly growing volumes of wood pellets, and is burning biomass at its domestic power plants.
- Japanese trading company Hanwa confirmed that rainforest is being cleared to establish an energy forest plantation for wood pellet production in Indonesia’s Sulawesi Island. Hanwa owns a stake in the project. The wood pellet mill uses cleared rainforest as a feedstock while the monoculture plantation is being established.
- A Hanwa representative defended the Sulawesi biomass project by claiming the area consists of previously logged secondary growth and that the energy plantation concession is not officially classified as “forest area.”
- The Japanese government is supporting biomass use across Southeast Asia through its Asia Zero Emission Community initiative, begun in 2023.
Peru’s modern history of migration and settlement (Dec 12 2024)
- Four roads with an enormous impact on rural Peru were built starting in the 1970s, incentivizing migration in the second half of the 20th century to the Amazonian lowlands from the Andean foothills.
- The largest single migratory destination in the Peruvian Amazon is landlocked Iquitos; immigrants arrived there in search of jobs in the oil industry. Currently counting more than 500,000 inhabitants, Iquitos is now the largest city in the Western Amazon.
- The cultivation of coca has had major impacts on the development of Peru’s Amazonian regions. Violent clashes between armed groups searching to dominate the activity have pushed as many as 450,000 people out of their homes.
Communities warn of threat to ecosystems from Brazil bridge project (Dec 12 2024)
- Islanders and experts have warned of widespread environmental and social impacts from the construction of a bridge linking the Brazilian city of Salvador with the island of Itaparica in Todos os Santos Bay.
- Critics say the project will devastate mangrove forests and coral reefs, leading to environmental imbalance, compromising fishing communities and threatening the survival of many marine species including humpback whales and sea turtles.
- Proponents say the bridge will boost development in the region, in particular transporting agricultural produce, but islanders say the anticipated population surge on Itaparica will create unsustainable pressure on public services as well as drastically change the dynamics of the community living there.
- Experts say the best solution for improving transportation links between Salvador and Itaparica is to invest in the existing ferry system, but this option wasn’t considered by planners.
Kenya embraces electric buses to combat air pollution (Dec 12 2024)
- The Kenyan capital Nairobi is slowly introducing electric buses into the fleet of notoriously noisy and polluting matatus that ply its streets.
- Drivers selected to operate these Chinese-made and locally assembled buses say passengers prefer them because they’re quieter, faster and more comfortable.
- The rollout is still on a small scale: the $200,000 price tag for an electric bus is prohibitive, but the manufacturer is leasing them to operators to make them more affordable.
- Charging is also an issue, with drivers reporting shorter ranges than advertised, and just three charging stations available in the city.
In 2024, Nepal’s elusive snow leopards pounce into spotlight (Dec 12 2024)
- The year 2024 marks significant milestones for snow leopard conservation in Nepal, one of the animal’s 12 range countries.
- A snow leopard was found roaming the country’s plains and provided a home in the country’s central zoo.
- With the launch of a new conservation action plan, the government has initiated a shift in its approach to save the animal.
- Snow leopards also found their way into the popular imagination of filmmakers and even cricket enthusiasts.
Wildlife conservation is a key climate change solution (commentary) (Dec 11 2024)
- It’s time for global leaders, funders, and policymakers to prioritize the inclusion of local conservationists in major climate discussions, a new op-ed argues.
- The effects of climate change, such as fires, droughts, and extreme weather events are not just environmental threats, but crises that directly impact human well-being and wildlife survival alike.
- “If we are serious about tackling climate change and preserving biodiversity, we must embrace holistic and inclusive approaches to conservation that integrate both wildlife and community needs,” two conservationists write.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Brazil natural landscape degradation drives toxic metal buildup in bats (Dec 11 2024)
- Bats play a crucial role in tropical regions as pollinators, seed dispersers and agricultural pest controllers. But they are exposed to a wide range of threats, pollution among them.
- Two recent papers show how natural landscape transformation and degradation, due to pasture and crop monoculture creation and mining in Brazil’s Atlantic Forest, can increase bioaccumulation of toxins and heavy metals in bat populations, leading to potential health impacts.
- Over time, this toxic accumulation could increase the likelihood of local bat extinctions and the loss of vital ecosystem services. The toxic contamination of these landscapes also poses a concern for human health, researchers say.
- These findings are likely applicable to bats living in other highly disturbed tropical habitats around the world, researchers say.
Andes glacier melt threatens Amazon’s rivers & intensifies droughts (Dec 11 2024)
- A new study found that Andean tropical glaciers have reached their lowest levels in 11,700 years, with drastic consequences for the Amazon due to the overlap of the two ecosystems.
- The findings come to light as record droughts in the Amazon in 2023 and 2024, exacerbated by climate change, have severely impacted local communities, including food insecurity and lack of access to drinking water.
- The ice loss in the Andes could reduce the water flow to the Amazon rivers by up to 20%.
- Venezuela is on the verge of becoming the first country in modern history to lose all its glaciers.
Environmental journalist in Cambodia shot and killed by suspected logger (Dec 11 2024)
- Free press advocates are demanding justice for environmental reporter Chhoeung Chheng after he was shot and killed by a suspected illegal logger on the outskirts of a protected area in northern Cambodia.
- Chheng and a colleague were in the region to document illegal forest activities when they encountered the alleged perpetrator on Dec. 4; police arrested the suspect the following day.
- Chheng died in hospital on Dec. 7, making him the latest victim in a broader trend in which covering environmental issues puts journalists in the firing line.
- Advocates say the incident underscores the threats to journalists seeking to cover issues such as logging amid increasing climate-related catastrophes across Asia, and have called on governments like Cambodia’s to ensure journalists can freely and safely report on those issues.
First-of-its-kind crew welfare measure adopted at Pacific fisheries summit (Dec 10 2024)
- The organization that sets fishing rules for a swath of the Pacific Ocean covering nearly 20% of Earth’s surface and supplying half the world’s tuna catch held its annual meeting in Fiji from Nov. 28 to Dec. 3.
- Parties to the Western and Central Pacific Fisheries Commission (WCPFC) adopted a landmark crew welfare measure — the first binding labor rights measure adopted by any of the world’s 17 regional fisheries management organizations.
- The parties, 25 countries plus the European Union, also adopted a voluntary measure to implement electronic monitoring of catches.
- However, they didn’t adopt a proposal to curb potentially dodgy ship-to-ship transfers known as transshipments, or substantive new protections for sharks and seabirds, as NGO observers had hoped.
Deadlocked plastic treaty talks will lead to renewed negotiations in 2025 (Dec 10 2024)
- In 2022, U.N. negotiators set a timetable to finalize a global plastics treaty by the end of 2024.
- That hope was dashed on Dec. 1 at the United Nations summit in Busan, South Korea, as a few oil petrostates and plastic-producing nations (seeking a voluntary treaty focused on waste reduction) blocked 100-plus higher-ambition nations (seeking a binding treaty with limits on plastic production).
- However, many parties feel that a strong agreement can still be reached, and say there’s good reason for hope: In Busan, participating nations agreed to a 22-page “Chair’s Text” for the treaty that will serve as the starting point for negotiations at a resumed session in 2025, perhaps as early as May.
- But much remains to be worked out, especially concerning limits on plastic production, proposed bans on some toxic chemicals used in plastics, a phaseout of some single-use plastic products, and more. A key sticking point is the question of who will pay for the treaty’s implementation and ongoing enforcement.
‘We have incredible & applicable solutions’: Interview with Peter Houlihan of XPRIZE (Dec 10 2024)
- XPRIZE Rainforest, a $10 million competition to come up with autonomous rainforest monitoring technology, wrapped up earlier this year.
- Four winners were announced in November for their work in combining cutting-edge technology and Indigenous knowledge to monitor a 100-hectare (250-acre) plot in the Amazon Rainforest within 24 hours.
- XPRIZE Foundation, the nonprofit organization that organized the competition, is now collaborating with governments and universities around the world to help scale up the technologies and deploy them for rainforest monitoring.
Construction of Indonesia’s new capital sees port activity crowd out fishers (Dec 10 2024)
- Construction of Indonesia’s vast new capital city on the east coast of Borneo has prompted a surge in port traffic in Balikpapan Bay, elevating existing pressures on the belt of mangroves lining the inlet.
- Local villages depend on near-shore fisheries within the inlet, but interviews indicate these communities are struggling to endure the increased port traffic and restrictions to fishing areas.
- District-level officials acknowledged that fishers face diverse challenges as a result of the new capital construction.
- However, they say they will seek redress for the destruction of any of the 16,000 hectares (39,500 acres) of mangroves in the bay area.
Thai citizens protest plans for Mekong dam amid transboundary concerns (Dec 10 2024)
- Citizens in northern Thailand staged protests along the shore of the Mekong River on Dec. 7 to draw attention to a controversial dam slated to be built on the river’s mainstream over the border in Laos.
- They demanded Thai banks and policymakers withdraw their support for the scheme due to its as-yet-unknown cross-border environmental and social impacts.
- The protests follow a particularly turbulent wet season marked by record-breaking floods that wrought high costs on riverside communities. Experts have said the dam would exacerbate such events should it be built.
- Halting the project to allow sufficient time for thorough transboundary ecological and social studies is absolutely critical, the activists said.
Satellites and lidar get AI boost to count forest carbon stock worldwide (Dec 9 2024)
- A newly launched tool combines satellite images, lidar data and artificial intelligence to estimate carbon stored in forests around the world.
- The Forest Carbon Monitoring tool, developed by Earth-imaging company Planet, trained an AI model using the organization’s archival satellite data and globally available lidar data.
- The model is now being used in conservation efforts as well as in the voluntary carbon market.
Narco airstrips beset Indigenous communities in Peruvian Amazon (Dec 9 2024)
- An investigation by Mongabay Latam and Earth Genome identified 45 clandestine airstrips in the rainforest in Peru’s Ucayali department.
- Thirty-one of these airstrips are located in Atalaya province, and of these, 26 are in or near Indigenous communities and reserves.
- These airstrips and the associated expansion of illicit coca cultivation began to increase in Atalaya 10 years ago, mirroring a rise in violence against Ucayali’s Indigenous communities and their leaders.
- Mongabay Latam spent five days exploring the areas most affected by drug trafficking in Atalaya, including the airstrips, and documenting the critical and alarming situation currently faced by communities in the region.
Gum-eating Tanzanian monkey is AWOL, fueling extinction fears (Dec 9 2024)
- There have been no confirmed sightings of Tanzania’s critically endangered southern patas monkeys for more than a year, raising fears the species is edging ever closer to extinction.
- In 2021, there were estimated to be fewer than 200 southern patas monkeys left in the wild, restricted to the western portion of Serengeti National Park.
- Researchers have appealed to members of the public to record sightings of the shy but distinctive animals, but only two separate sightings were made in 2022, one in 2023, and none so far in 2024.
- The species is due to be featured in the IUCN’s Primates in Peril, a list of the world’s 25 most endangered primates, for the second year running.
