Loggers and carbon projects forge odd partnerships in the Brazilian Amazon (Dec 9 2024)
- Mongabay examined four REDD+ projects in Pará state and found that all were developed in partnership with sawmill owners with a long history of environmental fines.
- The projects were developed by Brazil’s largest carbon credit generator, Carbonext, a company linked to a major fraud involving REDD+ projects and illegal loggers in Amazonas state.
- According to experts, REDD+ projects may have become a new business opportunity for individuals who have profited from deforestation for decades.

After historic 2024 coral bleaching, hope remains for Mesoamerican Reef (Dec 6 2024)
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.

‘Bear’s-eye camera’ reveals elusive Andean bear cannibalism and treetop mating (Dec 6 2024)
- Scientists captured the first-ever camera collar footage of wild Andean bears, revealing unprecedented behaviors, including canopy mating and cannibalism.
- The research team, led by Indigenous researcher Ruthmery Pillco Huarcaya, successfully tracked a male bear for four months in Peru’s challenging cloud forest terrain.
- The footage challenges previous assumptions about Andean bears being solitary vegetarians and shows them behaving more like other bear species.
- While the bears face mounting threats from climate change and human conflict, researchers are combining scientific study with community education to protect them.

That Cuban rodent species you never knew about? Turns out it’s two species (Dec 6 2024)
- New genetic research of museum specimens has found that the large rodents known as hutias on Cuba are two distinct species, not one as previously thought.
- ‘Capromys pilorides’ inhabits the eastern part of the island, and ‘Capromys geayi’ is found in the west, split by nearly 2 million years of evolution, likely due to a once-deep water channel that also divided Cuba.
- Scientists say the conservation status of both these is least concern, but threats such as deforestation, poaching and invasive predators remain.
- The eastern species may be a candidate for rewilding in the Cayman Islands, whose native hutia was closely related to Desmarest’s hutia and went extinct after the arrival of Europeans.

The uncertain future of Amazon river dolphins amid historic drought (Dec 6 2024)
- This year, the drought in Amazon rivers is already worse than in 2023, when 209 pink and grey river dolphins were found dead in Lake Tefé, in Amazonas state, largely due to overheating of the waters.
- To avoid a new tragedy, local organizations have taken action in advance, establishing emergency operations with stronger monitoring, staff training and equipment acquisition.
- However, no dolphin deaths due to heat stress have been recorded this year; instead, dozens of carcasses of aquatic mammals have appeared in Amazon lakes as a result of another sinister effect of drought: increased interactions with humans.

Students and scientists collaborate to maintain Navajo Nation forests (Dec 6 2024)
- Scores of saplings are choking out some pinyon pine forests in the southwestern United States, smothering the grasses that support ranchers.
- Researchers thinned small trees from a pinyon woodland in the Navajo Nation, creating an open forest that supports understory plant growth.
- Tribal and nontribal researchers and students from Northern Arizona University and Diné College on the Navajo Nation collaborated on the project.

Colliding icebergs and chirping seals: Polar ocean sounds are reimagined in art-science collaboration (Dec 6 2024)
- The United Nations declared the 2020s the UN Decade of Ocean Science for Sustainable Development to highlight the need for public engagement, citizenship, and connection to harness positive change for the world’s seas.
- Art and science collaborations can make the hidden depths of the oceans come alive for people via creative pieces drawing from real marine research.
- Researchers in Germany and artists from around the world united to highlight the sounds of the polar oceans through art projects created with recordings from the Ocean Acoustics Group at the Alfred Wegener Institute.

As Thailand’s blue swimming crabs decline, crab banks offer a sustainable solution (Dec 5 2024)
- Fishing of blue swimming crabs in Thailand has historically exceeded sustainable levels, leading to a decline in both the number and size of crabs that fishers were catching.
- Understanding the urgency of recovering the crab population, fishers, government agencies, NGOs and the private sector have rolled out a series of initiatives to make the fishery more sustainable.
- These include seasonal bans on harvesting egg-carrying crabs, restrictions on trawling and certain kinds of fishing gear, and the establishment of crab banks, where egg-bearing females are nurtured, with their hatchlings later released into a secure marine site.
- Fishers and experts welcome the crab banks, but emphasize the need for a “sustainable holistic scheme,” given that a reliance on crab banks alone won’t rebuild blue swimming crab populations.

Gaps in Peru’s peatland policies harm conservation and Indigenous Shipibo: Study (Dec 5 2024)
- Significant inconsistencies and gaps in science and policies for peatland protection in Peru’s Imiría Regional Conservation Area have led to long-standing conflicts with Indigenous Shipibo residents who argue the regulations restrict their livelihoods.
- According to researchers, the current local conservation policies inadvertently impose adverse effects on Indigenous livelihoods and negatively impact Indigenous sovereignty, therefore exacerbating existing tensions and mistrust between conservation authorities and communities.
- The absence of scientific data and lack of mention of peatlands in the area’s master plan means locals and policymakers are unaware of the importance of the critical ecosystem and policies aren’t well-informed, the researchers warn.
- Researchers and park management underline the importance of scientific support and the creation of participatory and effective governance frameworks that incorporate Indigenous perspectives and a more strategic approach to conservation.

Bolivia’s internal colonization and its March to the East (Dec 5 2024)
- Bolivia’s current configuration and its final area were consolidated after the Chaco War and after the country ceded Acre to Brazil and its coastal provinces to Chile.
- Since then, the need to occupy vast territories allowed for wide-scale deforestation, especially in the Chapare and the alluvial plain of Santa Cruz.
- In the department of Santa Cruz, population grew from about 300,000 in 1960 to more than three million in 2022. Although 70 % of this growth has been concentrated in the metropolitan area of Santa Cruz de la Sierra, the urban economy continues to rely heavily on agriculture.

Progress on rights complaint systems in Congo Basin but more needed, says group (Dec 5 2024)
- On November 27, the Rainforest Foundation UK (RFUK) released a report on data it collected on human rights complaints procedures at 24 protected areas in four Congo Basin countries.
- The data showed that only around a third had active grievance and redress mechanisms (GRMs), and that most suffered from shortcomings related to financing, participation, design and transparency.
- Of parks with procedures for community members to make complaints about human rights abuses, fewer than half kept a public register of those complaints or their outcomes.
- Salonga National Park in the DRC, site of some of the worst abuses in recent memory, was said to have the most advanced complaints procedure, but RFUK said there was still room to improve.

Pesticide exposure drives up rural women’s cancer risk in Brazil farming belt (Dec 5 2024)
- A study has found that women exposed to pesticides during farm work in Brazil’s Paraná state have a 60% higher risk of developing breast cancer, and a 220% higher risk of metastasis.
- While they don’t typically spray the pesticides, these women are responsible for cleaning the equipment and clothing used to do it, during which they rarely wear personal protective equipment.
- The study found glyphosate, atrazine and 2,4-D in urine samples from rural women; health and regulatory agencies consider these three pesticides as possibly or probably carcinogenic.
- Brazil has one of the most permissive pesticide markets in the world, where levels of exposure to chemicals like glyphosate are several times higher than in more strictly regulated jurisdictions such as the European Union.

Agroecology offers blueprint for resilient farming in northern Ghana (Dec 5 2024)
- Erratic rainfall and rising temperatures have hit farmers in Ghana’s semiarid Upper East region hard in recent years
- Planting rows of trees and allowing goats and sheep to graze their fields is helping retain soil moisture and fertility, while encouraging birds and bats to return, helping to control pests.
- The trees and small livestock also provide additional sources of income for farmers.
- These agroecological practices of alley cropping and mixed farming can be adapted to other drought-prone regions across Africa, proponents say.

Coral reefs could survive climate change, but in altered state, study says (Dec 5 2024)
- Coral reefs, vital for a billion people globally, face massive loss and potential collapse within decades due to rising ocean temperatures and acidification, even if emissions reduction targets under the Paris Agreement are met, scientists say.
- A new study challenges this prediction, suggesting reefs could adapt and avoid collapse, albeit with significant changes; it nevertheless highlights the need for ongoing reductions in local stressors and carbon emissions.
- The study tested the responses of experimental reefs, which included eight Hawaiian coral species and other reef-dwelling organisms, to various future ocean scenarios.
- However, some point out that such studies have limitations, such as not fully replicating reality or simulating the impact of further shocks on coral reef ecosystems, that reduce their predictive capacity.

In Chile, discovery of shallowest red hydrocoral forest yet surprises scientists (Dec 5 2024)
- Scientists have discovered massive marine forests in southern Chile’s Kawésqar National Reserve, formed by the red hydrocoral species Errina antarctica.
- These colonies, found at depths ranging from 1.23 to 33 meters (4 to 108 feet), are the world’s southernmost and shallowest known to date.
- Experts emphasize the importance of protecting these fragile ecosystems and hope the newly discovered forests will be considered in the reserve’s management plan.

Certified ethanol produced in Brazil for global airlines linked to slave labor (Dec 5 2024)
- Fuel produced from sugarcane in Brazil has become a strategic option for decarbonizing the aviation sector.
- But companies operating in this business have been linked to recent reports of labor abuses on sugarcane farms, a new report from Repórter Brasil shows. The rise in reports of labor abuses is partly attributed to the growing outsourcing of labor for planting.
- Workers hired via subcontractors lived in poor conditions without basic amenities, traveled long hours to reach the sugarcarne fields, and paid for their safety equipment.
- While certifications needed to access the fuel market are meant to protect workers, experts says certifiers are not doing enough to ensure fair working conditions and pay.

Severe drought in Peruvian Amazon isolated more than 130 Indigenous communities (Dec 5 2024)
- A severe drought that spread over recent months in Peru’s Loreto and Ucayali regions led to the isolation of more than 130 communities.
- Record low river levels affected the navigation of boats that deliver food and supplies as well as the health and livelihoods of communities that rely on fish for food and trade.
- Indigenous leaders from isolated communities have criticized the state for failing to deliver emergency assistance, such as drinking water and medical supplies.
- The frequency and intensity of extreme drought in the Amazon will continue to increase substantially due to climate change, experts warn.

Traditional fishers in Peru guard the coast from illegal fishing (Dec 5 2024)
- In Chimbote, north of Lima in Peru, fishers have been working for years to protect the Peruvian grunt (Anisotremus scapularis), a fish species in high demand for its meat, along a 1.5-kilometer (almost 1-mile) stretch of coast.
- Illegal fishing methods such as explosives have become common in this area, and the authorities have failed to deter them.
- The fishers, who use traditional methods to catch the grunt from shore, keep watch for illegal activities in the area in hopes that the species will not disappear.

DRC’s reliance on charcoal threatens forests and fuels armed conflict (Dec 5 2024)
- More than 90% of the population in the Democratic Republic of Congo rely on charcoal for their energy needs, driving the pervasive logging of forests across the country.
- One of the affected areas is Virunga National Park and its surroundings, the source of the wood for 92% of the charcoal used in North Kivu province.
- Activists and experts attribute the problem to the inaccessibility and high cost of grid electricity, as well as the fact that long-running armed conflict has led to 2.7 million people, out of North Kivu’s official population of 6.6 million, becoming internally displaced.
- Some initiatives underway aim to tackle the problem, including development of solar and hydroelectric power, and commercial tree plantations to produce charcoal, but none of these are at the scale required yet to make a meaningful impact.

Clouded leopard sighting raises questions about conservation and research in Bangladesh (Dec 5 2024)
- Clouded leopards occur in some South and Southeast Asian countries, but have fast been losing their habitat and, in 2021, IUCN declared the carnivore a vulnerable species.
- In Bangladesh, where there is no official record of the species, wildlife researchers studying other wildlife recently spotted clouded leopards in their camera trap footage, raising hope for their habitat conservation.
- Researchers have expressed concern about the lack of intensive research and conservation strategies for endangered species in Bangladesh.

Trees live out their lives in surprising ways, massive new study finds (Dec 5 2024)
- Trees have more complex life histories than previously thought, which scientists must consider to forecast greenhouse gases in the atmosphere and plan conservation efforts.
- Researchers assembled a dataset of 3.2 million tree measurements, covering more than 1,000 species across North and South America.
- Four “growth strategy” groups emerged, ranging from species that live fast and die young to those that live slow and die old.
- Carbon forecasts should take a more nuanced look at how long carbon is stored in this wide variety of trees, the scientists recommend.

Eastern U.S. floods could persist longer toward the end of the century (Dec 4 2024)
- Fifty years from now, floods in the eastern half of the United States will last longer as climate change creates warmer and wetter weather patterns, a new study suggests.
- Floods will last longest in the winter, the analysis predicts, marking a shift in damaging flood seasons.
- The trends underscore a need to renovate levees and dams, flood channels, and other infrastructure to protect residents and cities, researchers say. 

15 illegal narco-trafficking airstrips found near Peru Indigenous communities (Dec 4 2024)
- With the help of an artificial intelligence visual search algorithm, Mongabay Latam has identified 15 illegal airstrips.
- These airstrips are being used by drug traffickers to transport narcotics produced in the central rainforests of Peru, which are mostly bound for Bolivia.
- A team of journalists visited these areas and saw firsthand the fear gripping local Indigenous residents. Here, people avoid discussing the issue openly, as they struggle to survive amid an economy overshadowed by drug trafficking.

Why are Canadian moose declining? Interviews with Indigenous communities offer new clues (Dec 4 2024)
- Ecologists are unclear why moose populations in Ontario, Canada, have declined by 20 percent in the last two decades.
- University researchers and Indigenous community biologists combined peer-reviewed field studies and extensive interviews with First Nations tribal members to explore the possible reasons.
- Both sets of data pointed to climate change as the key factor, but stories and observations from tribal members offered many other potential causes overlooked by Western science.

Climate finance must empower grassroots conservation in Africa & beyond (commentary) (Dec 3 2024)
- “In the wake of COP29, which ended with developed economies begrudgingly committing to increase climate funding for developing countries to $300 billion, we must ask: will any of this funding get to those on the ground who are critical to the climate solution?”
- Small, African-led conservation organizations offer a powerful, cost-effective approach to climate action like in Madagascar, where grassroots organizations fill critical gaps by addressing the local dimensions of climate change, which are often overlooked in high-level strategies.
- By channeling climate finance to grassroots organizations like these, we can ensure that this path is not just paved with promises, but with sustainable and locally driven solutions, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
