Indigenous knowledge helps reveal the ties between reefs and mangroves
- A scientific collaboration between Australian scientists and First Nations Bardi Jawi rangers and elders has highlighted how fish species rely on the connectivity of reef and mangrove ecosystems.
- The study found that culturally important fish species, which form part of traditional fishery practices in the Kimberley region of northwestern Australia, migrated between the two ecosystems more than other species.
- The collaboration enabled Western scientists to draw on millennia of traditional ecological knowledge in carrying out the study and interpreting its findings.
- While most of the findings were already part of traditional ecological knowledge, rangers say they learned how certain species may not be able to survive if either reefs or mangroves were threatened by climate change and environmental impacts.
Marine conservation collides with mining in Indonesia’s biodiversity-rich Moramo Bay
- Pressure on a protected marine area in Indonesia’s Southeast Sulawesi province is growing as conservation efforts intersect with mining activity.
- Moramo Bay is part of the Coral Triangle, one of the world’s richest marine biodiversity regions, and provides habitat for humphead wrasse and other protected species.
- Researchers and officials say the health of its coral reefs and marine life is increasingly under scrutiny as development expands around the conservation area.
Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
A ‘leading’ Chinese miner of Mozambique’s heavy sands linked to environmental destruction
- Rapid loss of mangroves in Mozambique’s Zambezia Province is linked to the activities of Mozambique Heavy Sand Company VIII, which is part-owned by an influential Chinese mining group, Mongabay has found.
- The mangrove loss occurred inside a site considered “one of the most diverse and productive river delta systems in the world.”
- Satellite imagery suggests it was caused by what appears to be a blocked waterway where sand mining activities took place between 2022 and 2026.
- Increasingly, environmentalists are raising the alarm about the environmental impacts of heavy minerals prospecting and mining in vast sections along Mozambique’s coast.
A Sumatran villager lost ground to the sea. So he planted mangroves
In a coastal village on the Indonesian island of Sumatra, an oil palm and pineapple grower named Harisyah is fighting rapid coastal erosion. The region’s northern coastline, which sits on carbon-rich tropical peat soils, is losing ground to the sea at a rate of more than 6 meters (20 feet) annually. Researchers attribute the retreat […]
Nigeria can build the new coastal highway and also protect natural areas (commentary)
- To improve living conditions in Nigeria, new roads like the Lagos–Calabar Coastal Highway are needed.
- But these can and must be built in such a way that protects mangroves, swamps, and remnant forests, using knowledge and tools like environmental and social impact assessments.
- “The question is not whether Nigeria should develop. It is whether development will be intelligent enough to avoid destroying the natural infrastructure that already protects coastal communities,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
A deadly cross over: In South Africa, rabies moves from land animals to seals
- Cape Town, South Africa, has recorded 135 incidents of aggressive seal behavior toward humans since September 2021, including injuries that led to hospitalizations.
- Researchers suspect the cause is rabies, a disease normally associated with land animals but has leapt to Cape fur seals.
- Since May 2024, rabies cases have been confirmed in Cape fur seals along the Western Cape and Northern Cape coastlines of South Africa — the first time the virus has established itself in a marine mammal population anywhere in the world.
- Beyond attacks on humans, researchers worry whether the disease will spread to other marine mammals, as seals interact with different species.
Hermit crabs and cockroaches emerge as unlikely seed dispersers on a Japanese island
In the humid, coastal forests of Japan’s Ishigaki Island, near Okinawa, a parasitic plant relies on some unusual allies to spread its seeds: land hermit crabs and cockroaches, according to a recent study. The plant, fungus root (Balanophora fungosa), is non-photosynthetic, meaning it lacks chlorophyll and can’t make its own food. Instead, it grows as […]
Sand mining plans spark opposition from fishers in Indonesia’s Riau Islands
- Plans to mine marine sand off Indonesia’s Numbing Island have sparked opposition from fishers, environmental groups, and some lawmakers who warn of damage to fishing grounds and marine tourism.
- Although the government describes the project as marine sediment management and no company has begun operations, the proposal has divided local communities over the promised compensation.
- Critics warn the dredging could increase water turbidity, damage coral reefs, alter coastal currents, and weaken natural coastal defenses.
- The dispute has also raised legal and geopolitical concerns, with researchers arguing the Riau Islands’ strategic location makes the environmental risks a national security matter.
Land rights and mangroves entwine in a Brazilian quilombo’s resistance
- Officially recognized as a collection of quilombos, or traditional Afro Brazilian communities, by the government in 2023, Brejão dos Negros is still awaiting the land titles it has been demanding for 20 years.
- The federal land reform agency has demarcated more than 8,000 hectares (19,800 acres) of the territory, but the communities have been authorized to use less than a tenth of this area.
- This delay has left them vulnerable to land disputes; the encroachment of shrimp farms into mangrove areas, which harms fishing and shellfish gathering; and increased salinization of the São Francisco River, which affects their crops and hinders their access to potable water.
- Seeking new income sources, the community members are turning to pesticide-free farming; one of the communities has become the largest producer of agroecological rice in Sergipe state.
On fragile Sumatran peatland, a farmer fights to bring back lost mangroves
- A palm oil grower in an Indonesian village on Sumatra island, around 100 miles west of Singapore, has spent 15 years studying the role of mangroves in coastal ecosystems and pushing local action to restore coastal forests.
- Research shows this area of Sumatra’s northern coastline, which is separated from the Strait of Malacca by a narrow channel and the island of Bengkalis, is experiencing coastal abrasion of more than 6 meters per year, due primarily to mangrove loss.
- Indonesia pledged to restore around 600,000 hectares in five years by 2024, which researchers say was likely the world’s most ambitious reforestation initiative on record. However, only a small share of the planned planted area was successfully seeded.
Cambodia’s banned sand trade with Singapore appears to be back
- Cambodia appears to have resumed exporting sand to Singapore, despite a 2017 national ban, with Koh Kong provincial authorities saying a new dredging operation has been licensed.
- Mongabay traced at least four bulk carriers from Koh Kong to Singapore’s Tuas Port, where the site of a massive land reclamation project.
- The dredging is taking place within protected area boundaries and could affect riverbanks, fisheries and wildlife, as well as a major downstream mangrove forest.
- Environmental activists say they hope to draw attention to the renewed sand trade, but Cambodia’s shrinking civic space and restrictions on civil society groups have made standing up to environmental violations increasingly difficult.
Bangladesh plans to plant 250 million trees. Keeping them alive will be harder
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Bangladesh plans to plant 250 million trees over the next five years to expand green cover, restore damaged ecosystems, and support its climate and biodiversity commitments, reports Mongabay’s Abu Siddique. The government expects ministries, the army, local authorities, […]
Listening offers a clearer picture of India’s hidden finless porpoises
The Indo-Pacific finless porpoise is one of India’s smallest cetaceans, inhabits turbid coastal waters, and lacks a dorsal fin — all of which make it a difficult species for researchers to spot. Recent research suggests these animals are far more prevalent in Indian waters than visual sightings suggest, yet they may be disappearing before they […]
Extreme weather dampens breeding success for marine predators in Tasmania: study
- A recent study found that extreme weather events like storms, heat waves and floods can interfere with the breeding success of marine predators like seals, shearwaters and albatross that raise their young along the coasts of the Australian state of Tasmania.
- While some colonies appeared unaffected by extreme weather, others saw offspring swept away by powerful waves and storm surges, hypothermia during unusually wet episodes, and deadly overheating during periods of high temperatures.
- The researchers noted that these extremes are among many challenges seals, seabirds and other marine predators face, including pollution, disease and declining food supplies, which can also be influenced by extreme weather events.
Winners of the annual Mangrove Photography Awards: See the photos
In celebration of World Mangrove Day on July 26, the U.S.-based Mangrove Action Project (MAP) has announced the winners of its 12th annual photography awards. “Mangroves are the underdog. They will never be as glamorous as the Amazon rainforest or coral reefs. But through photography we can change that narrative, and intrigue people by showing […]
How saline drinking water raises preeclampsia risks in coastal Bangladesh (commentary)
- Climate change and rising sea levels are driving salt water intrusion into drinking water sources in coastal Bangladesh, which research links to an increased risk of preeclampsia, a leading cause of maternal mortality.
- Rural communities lack adequate freshwater infrastructure, which means pregnant women are often forced to consume saline water, making them particularly vulnerable to the life-threatening effects of excessive sodium intake.
- To address this hidden health crisis and prevent further maternal deaths, Bangladesh’s government and partner organizations must take urgent action by subsidizing household rainwater harvesting tanks for the most vulnerable coastal families.
- Since this article is a commentary, the views expressed are those of the author and do not necessarily reflect those of Mongabay.
US government announces plans to lease deep-sea mining rights in American Samoa
The U.S. government has taken another definitive step toward launching a deep-sea mining industry, starting in the waters of American Samoa, despite public opposition. On July 17, the Marine Minerals Administration (MMA), a new U.S. agency formed by merging the Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement, announced intentions […]
Beavers flourish in tidal habitats in the Pacific Northwest, study finds
Beavers are well-known residents of rivers, lakes and streams across North America. New research finds they are also far more common in estuaries and tidal wetlands than was previously understood. The study suggests the rodents are critical ecosystem engineers in a habitat where twice-daily tides raise and lower water levels, bringing saltwater inland from the […]
Melanesian nations announce intention to create massive ocean reserve corridor
- Solomon Islands is the latest Pacific island nation to sign on to a new network of marine protected areas (MPAs) known as the Melanesian Ocean Corridor of Reserves, or MOCOR, which was announced by Papua New Guinea, Vanuatu and Fiji at the first Melanesian Ocean Summit in May.
- Located in the southwestern Pacific, Melanesia is a hotspot for marine biodiversity and the discovery of new species.
- While large marine corridors can be more effective than isolated MPAs, researchers caution that robust management and enforcement are necessary to prevent them from becoming so-called “paper parks.”
- Details about MOCOR’s size, configuration, precise location, governance, enforcement mechanisms and community consultation processes are scarce.
From Mardi Gras to marsh: Glass Half Full turns party glass into Louisiana coastline
- A New Orleans based business, Glass Half Full, collects glass from bars, restaurants, and drop-off sites, recycling it into new bottles and fine silica sand.
- The recycled sand is used by ReCoast, the nonprofit’s restoration arm, to restore land by building small experimental islands and berms.
- Louisiana loses roughly a football field of land to the sea every hour, a crisis that Glass Half Full’s young founder, Franziska Trautmann, describes as a looming threat.
- Early results from the glass sand restoration is promising: vegetation is returning, sediment is sticking, and wildlife is moving in; but the work is constrained by two bottlenecks: not enough glass, and not enough funding.
Invasive giant prawn spreads through protected areas in Brazil
- A study led by researchers from Brazil and Uruguay confirmed the presence of invasive prawns in several conservation areas along the Brazilian coast, including estuaries listed by UNESCO as Natural World Heritage Sites.
- Considered an opportunistic predator and highly adaptable to different marine conditions, the giant river prawn competes with native species for food and shelter, in addition to being a potential vector for diseases.
- While scientists demand concrete actions to stop the advancement of this intrusive crustacean, small-scale fishers report significant drops in their capture of native animals, warning about the impact of invasive species on their livelihoods.
In the Canadian Arctic, an experiment aims to stabilize thinning sea ice
- Climate tech startup Real Ice is trialing sea-ice thickening in the Arctic coastal community of Ikaluktutiak, also known as Cambridge Bay, in Nunavut, Canada, where thinning ice affects many aspects of residents’ lives.
- The company is attempting to thicken the ice by drilling holes in it and pumping seawater onto the surface during winter, which activates refreezing.
- Work has been limited to a 1-square-kilometer (0.4-square-mile) test site in Ikaluktutiak, but the team hopes to scale up the project if it proves viable and environmentally safe.
- While the results have been promising, geoengineering projects like Real Ice’s work have also attracted controversy for the possible risks they pose to the environment.
How a spiritual practice is preserving Benin’s mangroves
In the West African nation of Benin, Vodun, an ancient spiritual religion rooted in a deep connection between humans and nature, has become a primary tool for protecting the country’s disappearing mangroves. By invoking the authority of the Zangbéto deity, local communities and conservationists create spiritual sanctuaries that forbid the destruction of mangroves under threat […]
Rising seas, garbage and heat threaten Brazil’s migratory shorebirds
- Among the many effects linked to climate change and damages to estuarine ecosystems, research indicates that migratory birds that depend on coastal wetlands could lose half of their habitats by 2050
- The impact is significant for Brazilian shorebirds: besides depending on a continuous chain of healthy wetlands to complete their long journeys between hemispheres, they suffer from the degradation of feeding areas such as mangroves.
- One the most threatened species is the red knot (Calidris canutus): low food availability could impair the bird’s preparation for the 8,000-kilometer (5,000-mile) journey it makes from Brazil’s northeast coast to the U.S. coast.
- Researchers are conducting censuses and conservation projects in areas of high shorebird biodiversity, including the Potiguar Basin in Brazil’s Rio Grande do Norte state, considered a “regionally important site” for these migratory birds.
Fossil fuel-based mega projects displace locals in Bangladesh, pushing youth out
- The Bangladesh government has adopted a master plan to develop Maheshkhali sub-district through three industrial zones: An energy hub with 13 gigawatts of LNG and coal power plants, a deep-sea port with container and multipurpose terminals, and a special economic zone.
- The development requires about 37,000 hectares of land across Maheshkhali and Matarbari coastal areas, potentially displacing more than 770,000 residents.
- A coal power plant and deep-sea terminal have already displaced 20,000 people by acquiring 2,820 acres of land used for salt production, fish farming and shrimp cultivation.
- The coal power plant and deep-sea terminal have affected more than 90,000 people, leaving many without livelihoods and pushing some to risk illegal migration to East Asia for work.
Southeast Asian mangroves shift from historic decline to net growth
For decades, Southeast Asia was the global epicenter of mangrove deforestation, but a recent study reveals a dramatic reversal: Since 2010, the region has transitioned from a net loss to a net gain in mangroves, making it a primary contributor to a global mangrove rebound. The study, which analyzed 40 years of satellite data, found […]
Scientists use AI to produce first high-resolution map of global seagrass extent
- Scientists have produced the first high-resolution map of seagrass ecosystems around the world.
- Data from the map reveal that 70% of global seagrass cover is concentrated off the coasts of just five countries.
- The map also found that nearly 80% of seagrass loss happened outside marine protected areas, emphasizing the importance of targeted conservation action.
- Seagrass ecosystems play an important role in protecting coastlines and carbon sequestration; however, they face threats from hurricanes, coastal development, and marine heat waves.
Bangladesh gets ready for its first release of tiger rescued from poachers’ trap
- In early 2026, the Bangladesh Forest Department rescued an adult female Bengal tiger from the Sundarbans from a poachers’ trap set for deer.
- The critically injured tiger was taken to the Khulna Wildlife Rescue and Rehabilitation Center. After receiving the treatment, she is now ready to be released back into the mangrove forest.
- Since this is the first release of its kind in the country, the authority is struggling to decide on the best process, including whether the tiger should be fitted with a satellite collar or monitored with camera traps after release.
- Since last year, the Forest Department has taken strict action against deer poachers by conducting raids and seizing large amounts of netting and other traps. The tiger’s rescue from a snare and the increased deer population are results of these efforts.
Can conservation change how the world sees the Strait of Hormuz? (commentary)
- If seen only as an oil corridor, the main question becomes how to keep energy moving, but this overlooks a much more important reality, that the Strait of Hormuz is biologically rich yet fragile.
- Featuring mangroves, seabird colonies, coral reefs, turtle nesting beaches and islands, it is a narrow ecological corridor through which the Persian Gulf exchanges water between the Gulf of Oman and Indian Ocean, connecting nature across borders.
- “If it is also seen as an ecological corridor, another question enters the room: how much ecological capital is the region willing to risk while trying to protect its political and economic capital?” a new op-ed asks.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Illegal fishing takes a toll on Australia’s sea cucumbers
- Researchers blame an increase in illegal fishing for the decline of sea cucumbers in a remote Australian marine park and say many other reefs in the country have also been affected.
- The Australian government has launched an operation to crack down on illegal fishing in the country’s Northern Territory where the problem is acute, including for high-value sea cucumbers.
- But as long as the market for sea cucumbers remains strong in China and other East Asian countries, experts say, wild populations of this slow-growing animal could collapse and put the health of reef systems at risk in Australia and beyond.
Listen to whales to improve connection, care & ocean health (commentary)
- From establishing conservation protections to developing tools to understand whale communication, the work of marine biologist David Gruber and oceanographer Sylvia Earle is grounded in the same belief: understanding leads to connection and care.
- While there have been remarkable conservation successes across the five decades of their efforts, the overall trend is clear: the health of the ocean is declining faster than efforts to protect it.
- “We still have an opportunity to leave future generations an ocean filled with life, wonder, and possibility. But this window is closing. The choices we make in the next decade will firmly shape the future of marine ecosystems,” the co-authors argue.

Australia’s seagrass meadows under pressure as climate change turns up the heat
- Australia is a global stronghold for seagrasses, the flowering plants that grow in coastal waters and bays.
- Seagrasses are unsung but vital ecosystem engineers: They stabilize sediments, provide habitat and food for marine species, help cleanse the water column of pollutants and sequester vast amounts of carbon dioxide.
- Across Australia’s waters, these undersea meadows are suffering as coasts are developed, seas are polluted and climate change continues to raise water temperatures.
- Conservationists are working to restore seagrasses and build resilience to preserve these vital marine ecosystems.
Can coastal infrastructure be engineered to harbor marine life instead of harming it?
- Living Seawalls is a global initiative that aims to make seawalls, marinas and other hard coastal structures more hospitable to marine wildlife by installing biodiversity-friendly panels, boulders and pilings.
- In 2025, Ireland’s first Living Seawalls installation was established at Kennedy Pier in the port town of Cobh, and marine life is already starting to colonize the panels.
- While researchers say the panels can help marine life colonize hardened coastlines, and stayed cooler than standard flat seawall surfaces, questions remain about their effect on seawalls’ main function of keeping waves at bay, leading scientists to suggest that design modifications may be needed.
Sea level rise is ruining coastal Bangladesh with salty water (commentary)
- Projections indicate that Bangladesh faces an amount of sea level rise that will bring major saltwater intrusion into precious freshwater supplies, plus human health impacts, flooding and rampant erosion across coastal areas.
- Though Bangladesh did very little to cause climate change, the nation is not without answers, including the government’s Delta Plan 2100, but it is not moving quickly enough to act on them in time to avoid the worst impacts, the author writes.
- “What has been missing is not knowledge or technology, but the institutional will to treat this like the emergency that it is,” the writer argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Wildlife’s unpredictable movements make climate-change planning difficult
- Ecologists expected many species to shift northward or upslope in response to warming temperatures, but only about half of observed range shifts so far align with their projections.
- Species responses are likely shaped by multiple factors — changing habitat, rainfall and food availability — not just temperature. Some species may be unable to move, trapped within a fragmented habitat.
- Research shows animals that move toward higher latitudes don’t necessarily fare better.
- These mismatches between predictions and reality create more uncertainty for conservation planning and how best to support species adaptation through corridors.
A coastal Philippine farm offers a blueprint for farming with wetlands
- The Glinoga Integrated Farm in the Philippines’ Quezon province uses permaculture techniques to grow crops in harmony with the surrounding coastal ecosystem.
- One study looking at permaculture farms across 11 provinces in the Philippines found that Glinoga had the highest level of crop diversity among the farms it surveyed.
- Farm operator Ninieveh Glinoga converted the farm to a permaculture system after decades of incapacity by relatives and tenants had left the farms soil degraded.
In Kenya’s Mida Creek, fishers confront a changing ocean with hope
- Scientists say that the oceans are warming and absorbing more than 90% of the excess heat trapped by greenhouse gases in the atmosphere. These rising temperatures are placing growing stress on marine ecosystems, fueling coral bleaching, disrupting breeding cycles of marine organisms, and reshaping fish habitats.
- In the Western Indian Ocean – including along Kenya’s coast – warming is occurring faster than the global average in some places, raising fresh concerns for communities whose food security and livelihoods depend on the sea.
- Along the shores of Mida Creek in Watamu, one of Kenya’s best-known coastal destinations on Kenya’s Indian Ocean coast, fishers say they are already feeling the effects. Many report traveling farther offshore in search of fish and returning with smaller catches than they did a generation ago.
- During a recent reporting trip, Mongabay met fishers and women involved in the fish value chain who spoke about declining catches and fears for the future. At the same time, they pointed to local efforts to restore mangroves, protect fish breeding grounds, and clean beaches as reasons to hold on to hope for Mida Creek’s future.
Can globally essential mangroves bounce back from deforestation? New study gives hope
- Human and natural disturbances have driven global declines of mangrove forests, which serve as critical protection for coastlines and fisheries.
- Scientists used satellite imagery of mangroves from 1984 to 2023, and found that after decades of decline, mangroves worldwide began to recover around 2010, mostly by expanding into new habitats, according to a new study.
- Recovery is not evenly distributed, the study found. Southeast Asia slowed mangrove loss while West and Central Africa have seen accelerated deforestation in recent years.
Protect Antarctic krill to preserve the health of Africa’s coastal communities (commentary)
- African leaders must demand an end to industrial krill fishing in the Southern Ocean while at the Our Ocean Conference this week, before irreversible damage is done, Angola’s Minister of Fisheries and Marine Resources warns in a new op-ed at Mongabay.
- Antarctica and the ocean systems upon which Africa depends rely on krill — the tiny crustacean that gathers in huge swarms and which whales, seals, penguins and fish species feast upon — so letting business interests dictate how the base of this important food chain, that millions of people also benefit from, is irresponsible, she writes.
- “What happens in Antarctica affects the global ocean. That means the whales migrating along African shores, the resilience of our coastal communities, and the health and livelihoods of our coastal communities,” the minister argues. “Please join me in calling for an end to krill fishing now.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Africa’s community-led marine organizations on which 30×30 depends
- More than 5,000 delegates are gathering in the Kenyan coastal city of Mombasa for a major global conference on the future of the oceans.
- At the heart of the discussions is ocean governance and the global push to meet the 30×30 target — protecting 30% of the world’s land, freshwater and oceans by 2030.
- But meeting that goal will depend not only on governments and international pledges, but also on community-led organizations doing the difficult work of conserving fragile marine ecosystems.
- Across Africa and around the world, thousands of grassroots groups are carrying out this work, often far from the spotlight, helping shape ocean conservation and blue economies that support local livelihoods. Mongabay spoke with representatives of four such organizations working across the continent from the Western Indian Ocean to Africa’s Atlantic coast.
How a popular spaghetti dish is threatening Italy’s marine ecosystem
- In the waters off Naples, Italy, a single 75-minute raid by poachers can net nearly 1,000 sea urchins, an in-demand ingredient in a dish popular with tourists. A haul like that can deal a significant blow to the local urchin population.
- In a healthy marine ecosystem, fish like sea bream feed on urchins, keeping populations in check. When poachers decimate sea urchin colonies, commercial fish move elsewhere to find food, threatening legal fishers’ livelihoods.
- Experts say Italy’s marine protected areas are particularly vulnerable. Although they have criminal penalties to deter poachers, the surrounding waters have been completely stripped bare of urchins, making them attractive targets.
- Now, scientists are collecting data from law enforcement operations to raise awareness and drive regulatory changes.
Plastic food packaging blankets the world’s coastlines, study finds
- A new study analyzed thousands of shoreline litter surveys and other data from more than 100 countries to produce the first global index of macroplastic pollution by type.
- The study found food and beverage plastics were the most common litter type for 93% of countries surveyed, followed by plastic bags and cigarettes; the pattern was consistent across countries, regardless of waste management infrastructure.
- Plastic pollution harms marine life and disrupts ecological services provided by coastal ecosystems like mangroves, coral reefs and seagrass.
- Researchers call for reducing production, warning that waste management alone will not solve the global plastic pollution problem.
Australia establishes the first Sea Country Indigenous Protected Area
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For the Karajarri people of Kimberley in northwestern Australia, the coastline, reefs, wetlands, beaches and desert-edge country form one estate, held through law, memory, work and obligation. That relationship now has new recognition, reports Mongabay’s John Cannon. In […]
‘Chemical cocktail’ of pharmaceuticals found in Djibouti coastal waters
Common medications that billions of people take for ailments like pain, fever and infections were detected in several sites along Djibouti’s Gulf of Tadjourah in East Africa, according to a recent study. Researchers found that untreated urban wastewater contained dangerous concentrations of anti-inflammatory medicine like ibuprofen, caffeine, and the antiepileptic drug carbamazepine, which were contaminating […]
In Indonesia’s Lombok, fishers find food security tied to mangrove reforestation
- On the east coast of Indonesia’s Lombok Island, local people who rely on the local crab fishery have initiated their own mangrove planting program in a bid to resuscitate failing crab habitats.
- The system is known as a silvofishery, which integrates mangrove forests with aquaculture cultivation to raise productivity.
- Instead of catching immature crabs from the coastline for quick sale, some local fishers have started to raise the crabs to adulthood alongside newly planted mangroves, garnering a higher price while overseeing a more sustainable population.
- However, local officials say a lack of technical training means most silvofishery initiatives have been forged through trial and error, and that expanding the system could result in greater mangrove planting in addition to boosting purchasing power in subsistence communities.
A year on, Australia’s biggest harmful algal bloom continues to wreak havoc
- The largest and longest-lasting harmful algal bloom in Australia’s history, which started in early 2025, has potentially affected more than 20,000 square kilometers of ocean waters and about a third of the coasts in the state of South Australia.
- The algal bloom has devastated marine ecosystems and caused significant economic losses in the local fishing, aquaculture and tourism industries.
- As officials, researchers and communities grapple with its ecological, health and social impacts, the bloom has exposed a lack of preparedness at all levels of government for responding to future HABs.
Despite oil spills in Nigeria’s mangrove forests, Shell continued operations, documents show
- Documents disclosed as part of a lawsuit against UK-based oil company Shell show leadership continued operating a compromised pipeline in Nigeria’s Niger Delta despite knowing it posed a pollution risk in the surrounding coastal wetland environment.
- According to locals in Bille, a town near the pipeline, oil spills between 2011 and 2013 killed thousands of hectares of mangroves and aquatic life that rely on the wetland ecosystem, impacting people who depend on fishing.
- Shell said organized criminal gangs were responsible for the spills and that shutting down the pipeline and removing illegal connections also came with security risks.
- The Niger Delta region is a globally important biodiversity hotspot, hosting four Ramsar Wetlands and the largest mangrove forest in Africa.
Genetic study reveals extinction risk for unique mangrove-adapted pampas cat
- The San Pedro de Vice dry mangrove habitat on the northwest coast of Peru hosts a very small population of desert pampas cats (Leopardus garleppi). It’s part of a population unlike any other across the species’ Latin American range, which stretches from southern Colombia to northern Argentina.
- While the desert pampas cat is normally found in arid deserts, dry forests or grasslands, this small coastal population is one of a kind in that it is uniquely adapted to a dry mangrove habitat bordered by desert.
- While camera-trap data initially suggested a healthy population in San Pedro de Vice, a recent genetic study performed on scat determined there are just nine cats in this isolated area, all of them related, with just two actively breeding — raising concerns this unique population can’t survival without conservation intervention.
- Researchers say this population’s story is a warning to conservationists that other small cat species worldwide thought to be thriving may be facing isolation and genetic bottlenecks in fragmented ecosystems, risking multiple local extinctions. But expensive genetic studies of hard-to-find scat make assessments difficult.
Indigenous communities in eastern Indonesia revive systems for marine protection
Across the small islands of eastern Indonesia that lie within the Wallacea region, one of the world’s richest marine biodiversity regions, coastal communities are reviving ancient customary systems to safeguard marine ecosystems from destructive fishing and habitat loss. This movement is the centerpiece of Jejak Wallacea, a recent documentary highlighting how local empowerment can succeed […]
Global sand demand is outpacing nature’s ability to replenish it, UN says
The global sand mining industry removes around 50 billion metric tons of material each year, outpacing the rate at which sand replenishes through the slow geological processes of weathering, reports Mongabay’s Carolyn Cowan. According to a report by the U.N. Environment Programme (UNEP), the demand for sand is expected to grow by 45% by 2060 […]
World Turtle Day: Important conservation wins amid turtle extinction crisis
World Turtle Day is celebrated every May 23 to raise awareness about the threats faced by turtles and tortoises. Turtles, tortoises and terrapins, which together make up the order Testudines, have evolved over millions of years, dating back to the Triassic period. However, recent reports show that more than half of the world’s 359 turtle […]
Mangroves are ‘powerful and undervalued’ for curbing nitrogen pollution, study finds
Mangrove forests could help sequester more than five million metric tons of nitrogen pollution from coastal ecosystems across the Earth if they are restored and protected, a recent study found. Nitrogen pollution typically comes from synthetic fertilizers largely used in agriculture or from human waste seeping into water sources. Nitrogen is an essential nutrient for […]
Thai island community rallies to protect beloved dugongs, revive declining seagrass
- Seagrass beds around the island of Koh Libong in Thailand’s Andaman Sea have died off in recent years, part of wider nationwide declines scientists say have multiple, complex causes.
- The seagrass shortage has devastated the island’s once famed dugong population, jeopardizing tourism businesses and impacting the island community who have long protected them.
- Locals frustrated by slow government seagrass recovery plans are working with researchers and conservation groups to build citizen science skills and trial seagrass restoration techniques.
- Signs of hope are emerging, with recent surveys recording more dugongs in local waters, prompting local leaders to call for increased public awareness and enforcement of protections.
Mexico rejects ‘Perfect Day’ waterpark on Caribbean coast, citing environmental risks
Environmental authorities in Mexico have rejected the proposal for a large waterpark in the southern state of Quintana Roo, citing risks for coastal ecosystems and local communities. Royal Caribbean’s Perfect Day Mexico would have covered more than 80 hectares (200 acres) in the village of Mahahual with the “ultimate vacation for families,” including pools, restaurants […]
19,000 Great Pyramids a year: Report flags unsustainable rate of sand mining
- A new analysis of global sand extraction indicates the industry is removing roughly 50 billion metric tons a year, a pace that far outstrips natural replenishment.
- Experts say the loss of sand from landscapes, river deltas, and coastal zones threatens ecosystems, livelihoods and many processes on which life depends.
- Although the sand mining industry is operating at unsustainable levels, experts say measures exist to lessen its impact.
- Solutions include coordinated governance, stronger monitoring and long-term, cross-border planning.
Monica Montefalcone, leading seagrass scientist, dies in Maldives diving accident, aged 51
- Monica Montefalcone, a University of Genoa marine ecologist and leading expert on Mediterranean Posidonia oceanica meadows, died in a diving accident in the Maldives at age 51.
- Her daughter, Giorgia Sommacal, 23, died with her, along with three other Italians, four of whom were connected to the University of Genoa.
- Montefalcone’s work linked field science, conservation practice and public understanding, especially through mapping, monitoring and restoring seagrass meadows and other coastal marine habitats.
- Colleagues and students remembered her as a demanding field scientist, generous teacher and clear communicator who helped younger researchers find their place in marine biology.
Karajarri celebrate Australia’s first ‘Sea Country’ Indigenous Protected Area
- The Kimberley region of northwestern Australia is a biodiversity hotspot and ancestral home of the Karajarri people, who recently dedicated Karajarri Jurarr Ngurra, Australia’s first “Sea Country” Indigenous Protected Area (IPA), covering around 237,000 hectares (587,000 acres) of marine and coastal ecosystems.
- Proponents of IPAs say they can empower Indigenous Australians as decision-makers in land management, combining traditional ecological knowledge with conservation goals.
- IPAs now account for 54% of Australia’s progress toward protecting 30% of its territory by 2030.
- While research shows every $1 invested in IPAs yields up to $3.40 in social, economic and environmental returns, advocates stress that Indigenous communities still need meaningful, sustained support.
In eastern Indonesia, communities revive customary systems to protect the seas
- A new documentary, “Jejak Wallacea,” highlights how coastal communities across eastern Indonesia are reviving customary marine management systems to protect ecosystems threatened by destructive fishing, turtle hunting and habitat loss.
- Communities featured in the film use locally rooted approaches including seasonal fishing closures, turtle hatcheries, mangrove restoration, customary sanctions and community patrols to manage reefs, fisheries and coastal forests.
- Conservation groups behind the project say community-led systems rooted in Indigenous and local knowledge can succeed where top-down conservation models and formal protected areas alone often fall short.
- The initiatives have helped protect species including sea turtles, dugongs and thresher sharks, but organizers say long-term success depends on stronger government recognition and support for community-based conservation.
Arabian Gulf’s fragile marine ecosystem threatened by current crisis (commentary)
- During the Iran–Iraq war of the 1980s and subsequent conflicts, large-scale oil spills and fires caused lasting environmental damage in the Arabian Gulf.
- A new commentary by United Arab Emirates special envoy of the minister of foreign affairs for nature Razan Khalifa Al Mubarak explains that recovery of impacted marine ecosystems, where it occurred, took decades, but that this progress is now threatened by the new conflict along the gulf.
- “What is at stake today is not only the repetition of past damage, but its amplification across interconnected systems,” she writes in arguing for an end to the current conflict.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Vodun’s sacred role in saving West Africa’s mangroves
GRAN POPO, Benin — In Benin, mangroves are said to be protected by the Zangbéto. In the Vodun belief, this deity forbids wood cutting, under penalty of a curse. As a result, in 10 years, more than 500 hectares (1,200 acres) of mangroves have been preserved thanks to this spiritual practice, which protects fragile and […]
Chesapeake Bay conservation bolstered by the power of business & viral videos
- Austin Lewis is small business owner in the Baltimore area who greatly enjoys his home waters, but he increasingly noticed how much trash floated or coated the bottom of his beloved Chesapeake Bay, and so decided to become part of the solution.
- His often humorous and always educational videos posted to various social media platforms garner huge attention and drive action by viewers to also do their part to improve water quality. The business allows him the flexibility to do this work daily, which in partnership with a local nonprofit, has removed millions of pounds of debris from the bay.
- In a new interview at Mongabay, Lewis shares his motivations and thoughts about the power of business to do good in the world.
Oil spill continues in Gulf of Mexico vulnerable habitats, while Pemex admits fault
- An oil spill has contaminated 933 kilometers (about 580 miles) of shoreline along the western Gulf of Mexico, impacting the Mexican states of Veracruz, Tamaulipas, Campeche and Tabasco in eastern Mexico.
- After two months of contradictory theories about what could have caused the spill, Mexico’s national oil company, Pemex, admitted the spill was caused by a leak in one of its pipelines.
- Local communities have had to reduce or stop their fishing and ecotourism activities due to a lack of information from authorities about the risks of coming into contact with the water, and despite a government-led cleanup, residents continue to document damages to the environment, such as oil-slicked vegetation and intoxicated or dead fauna.
- Conservationists say the containment of the spill is urgent for the protection of more than 1,000 marine species, among them, endangered Kemp’s ridley sea turtles whose nesting season is underway on the beaches of northern Veracruz and Tamaulipas.
Drones aid dugong conservation as threats mount across their range
- Drone technology is revealing new information about the elusive dugong, a marine herbivore classified as globally vulnerable but already extinct in parts of its range.
- Scientists are using drones to improve estimates of dugong numbers and conduct noninvasive health checks.
- Dugongs feed exclusively on seagrass meadows, where their foraging helps to maintain these important carbon sinks.
- Researchers are highlighting the need to link efforts to conserve seagrass meadows with protecting dugongs.
In Indonesia, a coastal vine used as medicine now signals ecological decline
- The beach morning glory (Ipomoea pes-caprae) vine is widely used as a traditional medicine in the north of Indonesia’s Sulawesi Island, and in many tropical coastal communities, to treat common complaints, and by fishers to treat stings from venomous fish.
- In addition to its medicinal use, the plant, also known as bayhops, reinforces beaches by binding sand dunes, increasing the resilience of global coastlines to risks of abrasion and erosion.
- Beach morning glory is a ubiquitous crawling vine, but some communities in Sulawesi’s Gorontalo province say the medicinal plant has disappeared locally due to industrial development and infrastructure construction.
Migratory species summit adopts new marine protections amid extinction warnings
- Delegates to the latest meeting of the Convention on Migratory Species of Wild Animals adopted new protections for 40 migratory species, including 33 marine animals like sharks, seabirds and shorebirds.
- The convention’s 15th Conference of the Parties (COP15), held in Brazil March 23-29, recognized the importance of “marine flyways” for migratory birds and highlighted key marine biodiversity areas.
- It also urged protection of seamounts from destructive fishing practices and a precautionary approach on deep-sea mining to address potential impacts on migratory species.
- Conservation advocates lauded the steps taken at COP15, but the summit also issued stark warnings that extinction and species decline are accelerating.
A French city cut its marine pollution — and its seagrass bounced back
- Neptune grass is generally regarded as the most ecologically important seagrass and shallow-water habitat in the Mediterranean Sea, where it is endemic. But the species has been in decline for many decades.
- A new study found that following the introduction of stronger environmental regulations and practices in the mid-to-late 1980s, Neptune grass (Posidonia oceanica) repopulated sampled sections of the waters off Marseille, France, over the ensuing four decades at rates that experts called “exceptional” and “remarkable.”
- The lead author said the study shows the value of passive restoration: letting seagrass meadows regrow on their own after removing the human-caused drivers of decline, rather than focusing on replanting or transplanting the species.
Green and gray: Mangroves and dikes show potential in protecting shorelines together
- A recent paper modeled how restoring mangroves in front of water-controlling infrastructure like dikes might create a hybrid coastal defense system in the face of global sea level rise.
- The model found that this combination, put in place today, could reduce the annual damage from storms and flooding by $800 million, and that 140,000 fewer people would be impacted by these events every year.
- They also found that these numbers would increase over time with the impacts of climate change.
- The researchers also evaluated where these projects would be most cost-effective, finding that the benefits disproportionately help lower-income areas, particularly in Southeast Asia, South Asia and West Africa.
State fishing village plan in Indonesian Papua sparks Indigenous opposition
- Indigenous Wiyagar leaders in Indonesian Papua oppose a planned state-backed fishing village, saying it’s being pushed without proper consultation on their customary land.
- The project is part of a nationwide program to build thousands of “modern” fishing settlements, a key plank of President Prabowo Subianto’s maritime development agenda.
- Critics warn the initiative risks “blue injustice,” as top-down planning may sideline local livelihoods, cultural systems and legal rights to participation.
- The dispute underscores broader tensions in Indonesian Papua over Indigenous land rights, with concerns that fast-tracked national projects could deepen land conflicts and environmental impacts.
The underwater meadows that help keep beaches from disappearing
Seagrass meadows, which rarely draw the attention given to coral reefs or mangrove forests, perform a steady but important task: they help hold coasts in place. The plants anchor themselves in sediment through dense root systems that bind the seabed, similar to how forests stabilize soil on land. Oscar Serrano Gras, a researcher affiliated with […]
Baby octopus in Argentina: Photo of the week
These eggs belong to a small octopus known in Argentinian Patagonia as pulperos. The Patagonian octopus (Octopus tehuelchus) is one of the more common octopus species in the region, but researchers still haven’t been able to determine its global conservation status, although reported catches in Patagonia have declined over the past 50 years. The photo […]
On Manatee Appreciation Day, remember these gentle giants who protect aquatic ecosystems (commentary)
- Slow-moving, peaceful and curious, manatees quietly maintain the health and balance of aquatic ecosystems, from rivers to bays and coasts worldwide.
- Manatee Appreciation Day is observed annually on the last Wednesday of March, and it’s a good time to remember why these animals matter, and the people who have dedicated their lives to protecting them.
- “The gentle giants of our oceans have survived for millions of years. Whether they survive the next century depends on all of us,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
PNG’s New Ireland coastal waters causing fish deaths, human sickness
- Communities on the east coast of Papua New Guinea’s New Ireland province report that contact with the seawater there has made people sick since December 2025; residents have also reported spikes in the number of dead fish and other marine life along the shoreline.
- A group of local and international NGOs has responded, providing help with sampling to determine the cause and raising money for the affected villages.
- New Ireland’s coastal communities depend on the sea for food, but government officials have warned against eating fish until the cause of the problems has been identified.
- Government ministries have been aware of the situation for at least two months, and while leaders say that tissue, water and soil samples have been collected, no results have been released yet.
Accidental discovery reveals new climate threat to emperor penguins
- Scientists have discovered new sites in Antarctica where emperor penguins gather for their annual molt, a vulnerable life stage when they shed and replace all their feathers.
- Through satellite data, they also discovered that many of these sea ice sites might have melted from under the penguins.
- The discovery suggests that the threats posed by global warming to emperor penguins might be more dire than previously thought.
Why saving seagrass meadows could help save the world’s coastlines
- Seagrass is known for its blue carbon potential, but meadows also play an important role in coastal protection by helping reduce wave intensity and stabilizing sediments, both of which are key to reducing coastal erosion.
- Experts point out that seagrass brings multiple other benefits, such as improving water quality that helps the marine environment, including coral reefs.
- Yet seagrass meadows across the globe face declines due to multiple stressors, including climate change.
- Conservationists and researchers are working to restore meadows and help them become resilient to increasing ocean temperatures and potentially devastating marine heat waves.
If Florida reefs aren’t protected, storms will increase flooding & costs: Study
- Coral reefs absorb incoming waves, protecting shorelines from tropical storms.
- A recent Earth’s Future study examines flood risks from tropical storms to communities in Florida, if coral reefs keep degrading at current rates.
- The study finds that future coral reef degradation will increase the annual risk of flooding to people by 42% and to buildings by 47%.
- This increased degradation would predictably cause $412.5 million in damages to structures and economic disruption of $438.1 million annually.
Bangladesh sees rise in ray, shark fishing as traditional seafood species dwindle
- Bangladesh has seen a sudden rise in illegal shark and ray fishing and consumption in recent years.
- A decrease in catch of traditionally consumed fish species and the lower prices of sharks and stingrays have led to this rise in popularity. Additionally, traders export ray skins and shark parts to East and Southeast Asian countries.
- Sharks and rays are protected species in Bangladesh and existing laws prohibit their catching, selling and consumption.
- Conservationists blame the weak law enforcement and lack of awareness among fishers and suggest that the government initiate stricter conservation measures besides providing subsidies to the poor fishers.
Plastic, from home and abroad, spills into Türkiye’s waters
- Türkiye has become a major destination for plastic waste recycling, notably from Europe and the U.K. Most of this scrap heads to the roughly 180 waste facilities handling plastic in Adana province.
- But large quantities are dumped along riverbanks or escape the facilities through their wastewater and eventually flow downstream into the Mediterranean Sea.
- The resulting pollution is taking a toll on riverine and marine ecosystems, including important sea turtle nesting sites.
- Some experts say Türkiye should stop importing plastic altogether to stem the tide of pollution, but the government has said the recycling industry plays an important economic role.
Avian flu strikes California’s northern elephant seals; area quarantined
- Experts confirmed that seven young northern elephant seals on the beach at California’s Año Nuevo State Park carried a deadly form of avian influenza, H5N1, the first recorded infection in these seals.
- This highly contagious virus has circulated the globe since 2020. The U.N. estimates that as of December 2025, H5N1 had infected some 598 bird species and 102 mammal species. In 2022-23, the virus devastated seal colonies off South American coastlines, sparking increased surveillance of North American marine mammals.
- This northern elephant seal population has been carefully studied for about 60 years. With close monitoring, researchers quickly discovered that sick pups were infected with Highly Pathogenic Avian Influenza H5N1.
- Since this avian flu strain emerged, there have been 131 human infections globally, including 71 in the U.S. As a precaution, California officials have banned visitors from the elephant seal beaches and canceled guided tours.
Panama NGOs face lawsuits, asset seizures in fight over port construction
- Two environmental groups fighting the Puerto Barú project in Panama have been named in lawsuits claiming they defamed the developers and created public confusion about the project.
- The Center for Environmental Advocacy of Panama and the Adopt a Panama Rainforest Association (Adopta Bosque) say the port could damage mangroves and harm vulnerable shark and ray species.
- Both organizations have had their assets seized, including bank accounts and properties that serve as private nature reserves.
Why so many mangrove restoration projects fail
Mangroves have become a favored solution in climate and conservation circles. They absorb carbon, blunt storm surge and support fisheries. Funding has followed. Yet outcomes often lag ambition. In parts of Southeast Asia and Latin America, research suggests that roughly 70% of restoration projects struggle to establish healthy forests. Seedlings die. Sites flood incorrectly. Community […]
In Kenya’s Jomvu Creek, women help restore a vanishing coast through crab farming
- On the outskirts of the coastal Kenyan city of Mombasa, a women’s organization in Jomvu Creek aims to transform livelihoods and the environment through mud crab farming.
- A blue economy grant is allowing the women to establish a crab-fattening enterprise and build a boardwalk through the creek, with hopes of boosting ecotourism.
- In a good month, the women’s crab sales amount to $310, meaningful income in an area where many had said they were living hand to mouth.
- Beyond income, the Jomvu women see themselves as caretakers of the creek, linking crab farming to mangrove restoration and planting nearly 1 million seedlings; the trees stabilize the shoreline, reduce erosion and create nursery habitats for fish and crabs.
Cambodia’s canal mega-project threatens coastal communities and marine life
- The Cambodian government is set to begin construction of the Funan Techo Canal, a nearly $1.2 billion, 180-kilometer (112-mile) waterway navigation project that will cut across four provinces to connect the Mekong River to the sea.
- The primary rationale for building the canal is to reduce Cambodia’s shipping costs as well as to generate jobs and economic development.
- Mongabay has followed this mega-project’s development for more than a year, speaking with more than 50 people living along the canal’s proposed route. Virtually everyone we spoke with noted that the government has provided very little information about the project, and amid the uncertainty, fear has taken root.
- In coastal communities in Kep province, where the canal will meet the sea and a new port and deepwater shipping lanes will be built, fishers we spoke with said they worried they’d lose their homes and that construction would render their already meager fishing grounds barren and inaccessible.
How intermediaries are reshaping mangrove restoration
- Despite growing global interest in mangrove conservation and restoration, many projects fail; experts say one reason is that restoration efforts are often led by small community groups with limited resources and expertise.
- Over the past five years, Seatrees, a California-based NGO, has supported mangrove restoration projects in Kenya, Mexico, the U.S. and Indonesia by providing funding to scale up tree planting, produce storytelling materials and build capacity in science, monitoring and impact measurement.
- In Kenya, where their restoration efforts are most advanced, Seatrees and its local project partner have supported more than 30 community groups to plant more than 1 million mangrove seedlings, maintain nurseries, dig trenches to improve hydrology and patrol forest areas for illegal logging — while paying participants for this important work.
- Seatrees has recently funded the creation and operation of a mangrove seedling nursery in the Florida Keys, run by CoastLove, a local NGO that engages residents and tourists in hands-on activities.
Seagrass restoration in Malaysia finds multi-species approach boosts recovery
- Seagrass restoration is increasingly recognized as crucial for addressing the twin crises of biodiversity loss and climate change.
- However, much remains unknown about the most effective techniques, especially in tropical ecosystems where long-term projects struggle for funding.
- A decade-long seagrass recovery program in Peninsular Malaysia has achieved high survival rates at a site heavily impacted by coastal development, raising hopes that degraded meadows can be revitalized.
- The study also identified several factors that can increase success, including: knowledge of the biology of local seagrass species, adapting methods to suit local environmental and physical conditions, and properly addressing the original drivers of decline.
A ‘new baseline’: Study captures accelerating sea-level rise in Africa
- Sea-level rise has accelerated across Africa in recent decades, thanks to global warming and, in particular, to the melting of ice sheets and glaciers, according to a recent study.
- Sea levels across the continent have risen four times faster since 2010, on average, than they had in the 1990s. About 80% of the sea-level rise is due to added water mass from meltwater.
- The impacts include flooding, erosion of coastal land, intrusion of salty seawater into freshwater drinking sources and displacement of coastal communities.
- In many coastal areas, sea-level rise occurs even as the land itself is sinking due to groundwater extraction or other factors, exacerbating its impacts.
More than 5 years after Wakashio oil spill, questions linger in Mauritius
- In 2020, amid the chaos of the pandemic, the island nation of Mauritius was hit by one of the worst environmental disasters in its history when the MV Wakashio, owned by Nagashiki Shipping, crashed into the coral reef barrier off the southeastern part of the island.
- The ship spilled around 1,000 metric tons of oil into the waters near three sites of ecological importance; more than five years on, conservationists and fishers say the Mauritian government quietly allowed the entire episode to fade from public memory, with little scrutiny.
- When Mongabay visited mangroves in 2025 that had been affected by the oil spill, fuel oil still lingered in the water-soaked earth; it could persist for decades, experts warn.
- Vikash Tatayah at the Mauritian Wildlife Foundation facilitated the evacuation of animals considered at risk due to the oil spill, including lesser night geckos, to the U.K.; eggs from the geckos and their descendants were returned to Mauritius in 2025.
From south to north, Sri Lanka’s cricket dreams undermine fragile ecosystems
- Sri Lanka plans to construct an international cricket stadium and a sports complex on the northern island of Mandaitivu spanning more than 56 hectares to popularize the sport in the country’s Northern province.
- Mandaitivu overlaps with mangroves and coastal wetlands in the ecologically sensitive Jaffna lagoon, and environmental groups warn that a construction on the low-lying island could reduce flood retention and increase climate vulnerability.
- Mandaitivu’s mangroves support fisheries and coastal livelihoods causing concern about potential decline in aquatic creatures, especially prawns and crabs, impacting the traditional fisherfolk.
- Conservationists say the project echoes past ill-informed infrastructure decisions, such as the Hambantota stadium built within an elephant habitat, reflecting weak environmental governance and repeated ecological trade-offs.
Democratizing AI for conservation: Interview with Ai2’s Ted Schmitt and Patrick Beukema
- OlmoEarth is a platform that integrates multiple AI models to extract meaningful insights from environmental data.
- The platform, developed by nonprofit organization Allen Institute for AI, is trained on 10 terabytes’ worth of Earth observation data.
- The platform enables researchers as well as conservation organizations to analyze massive data sets by customizing AI models on the platform.
Up close with Mexico’s fish-eating bats: Interview with researcher José Juan Flores Martínez
- The fish-eating bat (Myotis vivesi) catches fish and crustaceans thanks to its long legs, hook-shaped claws and waterproof fur.
- The species is found only on islands in Mexico’s Gulf of California; it’s considered endangered under Mexican law.
- Invasive species such as cats and rats threaten the bats.
- Researcher José Juan Flores Martínez has been studying fish-eating bats for more than 25 years, and discusses his fascination with the species and the threats it faces.
Top ocean news stories of 2025 (commentary)
- Marking the midway point in the U.N. Decade of Ocean Science for Sustainable Development, 2025 was a key year for the ocean.
- The past 12 months brought landslide multilateral wins for ocean policy, unprecedented ocean financial commitments, and increasing momentum to protect 30% of the ocean by 2030.
- Here, marine scientists, policy experts and a communications expert lay out the key ocean stories from the past year.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Huge ‘blue carbon’ offsetting project takes root in the mangroves of Sierra Leone
- In October, a wholly owned subsidiary of West Africa Blue, a Mauritius-based company, signed a “blue carbon” offsetting deal with the 124 communities on the island of Sherbro in Sierre Leone.
- The agreement will reward the communities financially for conserving and restoring their mangroves, which act as a carbon sink.
- The funds will be generated by selling offsets on the voluntary carbon credit market, with revenues shared between West Africa Blue, the communities and the government of Sierra Leone.
- Though carbon offsetting projects have been subject to criticism in the past, community members on Sherbro say they’re optimistic about the improvements to their livelihoods that the project could bring.
As Cyclone Ditwah battered land, Sri Lanka’s oceans absorbed a silent shock
- Following the tropical Cyclone Ditwah, unusual sea-foam appeared along parts of Sri Lanka’s northern coast, a natural phenomenon caused by storm-driven turbulence and organic compounds released by plankton, not marine pollution, scientists say.
- Extreme rainfall from Ditwah released an extraordinary volume of freshwater into the ocean, and researchers estimate that nearly 10% of Sri Lanka’s average annual rainfall was received in a single day and rapidly drained to sea through the island’s river network.
- Flood-driven sediments and sudden changes in salinity may stress coral reefs and coastal ecosystems, but Sri Lanka lacks systematic sediment monitoring at river mouths, leaving scientists with limited data on downstream impacts.
- The floods also swept plastics, debris and nutrients into coastal waters, potentially intensifying plankton blooms and fish aggregations while increasing the risk of algal blooms, oxygen depletion and long-term marine pollution.
Photos: Tourism ambitions clash with local livelihoods on Indonesia’s Lombok Island
- Residents of Tanjung Aan Beach on the Indonesian island of Lombok say they were evicted with little notice or compensation as the Mandalika tourism project advances, leaving many without livelihoods or alternatives.
- The government-controlled developer has defended its process, citing compensation paid in a different land zone, but locals say support didn’t reach the coastal community now being cleared.
- Perspectives diverge sharply: locals describe loss, fear and declining income, while some foreigners and investors argue the development is legal, overdue and ultimately beneficial.
- Younger Lombok residents highlight deeper systemic issues — weak regulation, rising costs and limited opportunities — saying tourism growth increasingly serves visitors, not locals.
A flood of logs post-Cyclone Senyar leaves Padang fishers out of work
- Flash floods in late November swept timber and mud from upstream forests into coastal waters around Padang, blocking access to the sea and cutting off the livelihoods of hundreds of fishers.
- Fishers say massive floating logs have damaged boats and halted daily incomes, forcing many families to rely on credit to meet basic needs.
- Marine scientists warn that suspended sediment and decaying timber threaten coastal ecosystems by blocking sunlight, disrupting food chains and degrading water quality.
- Environmental groups link the disaster to illegal logging and weak forest governance upstream, calling for stronger law enforcement, national disaster status and urgent government action.
As storms surge & the sea rises, Belgium builds dunes for protection
- Belgium is trialing “dune-by-dike” systems as a nature-based defense against storm surges and sea-level rise, using engineered sand dunes in front of existing dikes to create a double buffer along vulnerable stretches of coast.
- There are four dune-by-dike pilot sites in Belgium, including a 750-meter site in Raversijde, a neighborhood in the coastal city of Ostend, which Mongabay visited in late November.
- The Raversijde dune-by-dike project was established in 2021 with grids of vegetation that collected sand as the wind blew, helping build up the dunes.
- While experts said they believe dune-by-dike systems could protect large portions of the Belgian coast, they said building and maintaining the dunes relies on dredging sand from the sea to replenish adjacent beaches.
Marine heat waves and raw sewage combine to put human health at risk
- Climate change is fueling an increasing number of marine heat waves across the globe.
- When this intensifying heat is coupled with pollution — especially sewage, nitrogen fertilizer agricultural runoff, wildfire soot and possibly plastics — waterborne bacterial pathogens can multiply, raising human health concerns.
- These connections are exemplified in the escalating spread of Vibrio, a group of naturally occurring bacteria whose numbers are multiplying and undergoing global distribution shifts due to complex relationships between marine heat waves and pollution.
- Vibrio infections can range in severity but can result in sickness and death. One notorious Vibrio species is known as the flesh-eating bacteria; another causes cholera.
As fish catches fall and seas rise, Douala’s residents join efforts to restore mangroves
- Cameroon’s coastal fisheries are in decline, leaving fishers with dwindling catches — a crisis linked directly to the depletion of the country’s mangroves, experts say, which are breeding grounds for fish.
- The expansion of urban settlements, conversion of coastal land for agriculture, and sand extraction drives mangrove loss in Cameroon; another key driver is the use of mangrove wood for smoking fish.
- The Cameroon government and NGOs have set themselves an ambitious goal of restoring 1,000 hectares (nearly 2,500 acres) of mangrove forests by 2050.
- A key strategy involves engaging local communities in the replanting process and providing alternative livelihoods, such as urban farming and beekeeping, to reduce dependence on mangrove wood.
Philippine mangroves survived a typhoon, but now confront a human-made challenge
- A new study shows mangroves in Tacloban, the Philippine city hit hardest hit by Typhoon Haiyan in December 2013, have expanded beyond pre-storm levels.
- This recovery was driven by community-led reforestation efforts from 2015-2018, when residents planted 30,000 Rhizophora mangrove seedlings across 4 hectares (10 acres) of Cancabato Bay.
- Satellite image analysis and modeling reveal how the forest was destroyed by Haiyan and how it later withstood 2019’s Typhoon Phanfone.
- However, experts warn that the recovering mangroves may be threatened by an ongoing project to build a causeway across the bay, which could generate pollution and physical disturbances.
Scientists push for greater climate role for Latin America’s overlooked ecosystems
- Tropical forests are rightly regarded as important carbon sinks and crucial in the fight against climate change, but other tropical ecosystems have largely gone overlooked despite their carbon -sequestration potential.
- Peatlands, mangroves, coastal freshwater wetlands and seagrass meadows are just some of the ecosystems that have a potentially huge capacity to capture and store carbon, but don’t feature prominently enough — or at all — in the national climate plans of Latin American countries.
- Peatland soils can store between three and five times more carbon dioxide than other tropical ecosystems, with similar figures for mangroves and coastal freshwater wetlands.
- Seagrass meadows cover just 0.1% of the ocean floor, but can store up to 18% of global oceanic carbon.
Filipinos wade through floodwaters due to sinking land, rising sea & corruption
- Rising sea levels and sinking lands are leaving communities in the Philippines with the challenge of adapting to a combination of hazards that are reshaping coastal and island life.
- Globally, around 40% of the population lives in coastal areas, with more than 850 million people in low elevated coastal zones less than 10 meters above sea level, including more than 150 million living less than 5 above sea level.
- Between 2000 and 2019, an estimated 1.6 billion people were affected by different types of flooding, threatening infrastructure and disrupting basic services.
- On July 28, Philippine President Ferdinand Marcos Jr. in his State of the Nation Address ordered an investigation into possible corruption in flood control projects; since then, the scandal has ignited a broader anti-corruption movement among Filipinos.
Indigenous knowledge and science join forces to save the choro mussel in Chile
- In southern Chile’s Huellelhue River estuary, three Mapuche Huilliche communities are leading efforts to restore the natural beds of the choro mussel through a participatory governance model that brings together ancestral knowledge, science and education.
- Intensive harvesting during the 1990s led to the collapse of this mollusk, disrupting local ecosystems and the livelihoods of coastal communities.
- After confirming the mussel’s critical state, a total harvesting ban was declared in 2019; the communities formally requested that the Undersecretariat of Fisheries and Aquaculture extend it to 2026.
- Thanks to the ban, the mussel population is now showing clear signs of recovery, while Indigenous communities and experts implement a sustainable management plan and a laboratory-based repopulation program.
How community custody empowered Ecuador’s crab catchers and revived its mangroves
- Under agreements for sustainable use and protection, Ecuador’s environment ministry has granted concessions for 98,000 hectares (about 242,000 acres) of mangrove forests to artisanal fishers in the Gulf of Guayaquil.
- The fishers can catch crabs to sell, but are committed to the protection of this valuable ecosystem, imposing closed seasons twice a year and refraining from catching female and juvenile crabs.
- The concessions represent 62% of the total area of mangrove forests in Ecuador, of which 80% are located in the Gulf of Guayaquil.
- This system has allowed for the conservation of mangroves for 26 years and has been shown to be effective in protecting this type of forest, which is capable of retaining up to five times more carbon than other tropical forests.
COP30: What did it deliver for the ocean?
- As climate change talks took center stage at COP30, a growing number of countries have integrated ocean-based solutions into their national climate commitments.
- A new report found that 92% of coastal and island nations’ updated climate plans now include ocean-related measures, although these strategies still represent only 12% of all proposed climate mitigation actions.
- Brazil and France unveiled a Blue NDC Implementation Taskforce to boost ocean solutions, while countries like the Solomon Islands and Ghana launched new plans for protecting their marine and coastal systems.
Construction of TotalEnergies pipeline cuts through coral reefs in Mozambique
- A Dutch company dredged through a highly sensitive coral area for TotalEnergies’ liquefied natural gas project in Mozambique, satellite imagery and vessel traffic data confirm.
- The French oil and gas company declared force majeure after insurgents attacked the facility in 2021, but some work on the project continued.
- Environmental groups warn that the environmental impact assessments for TotalEnergies’ project and three others in the same waters are inadequate.
Sierra Leone communities sign carbon agreement based on carbon justice principles
- Hundreds of communities in Sierra Leone’s Bonthe district have signed a benefit-sharing carbon agreement with the Africa Conservation Initiative targeting the protection of mangroves in the Sherbro River Estuary.
- The agreement is based on “carbon justice principles” aimed at making carbon projects fairer for communities, such as a 40-50% gross revenue share; free, prior and informed consent, including transparency of financial information and buyers; and community-led stewardship of the mangroves.
- If implemented correctly, the agreement could address “deep-rooted issues of fairness,” experts say.
‘Not good’: Ocean losing its greenness, threatening food webs
- The ocean is losing its greenness, a new study has found: Global chlorophyll concentration, a proxy for phytoplankton biomass, declined over the past two decades, especially in coastal areas.
- Phytoplankton are the base of the marine food web, supporting fisheries and broader ecosystems, so their decline could have far-reaching implications, experts say.
- The phytoplankton decline could hurt coastal communities that live off the sea, and affect the ocean’s ability to act as a carbon sink, the authors say.
Scientists call for stronger action to save Indonesia’s vanishing seagrass meadows
- Marine experts at the Indonesian Seagrass Symposium in Bali warned that seagrass ecosystems — vital for carbon storage, biodiversity and coastal protection — remain largely overlooked in national policy and conservation efforts.
- Seagrass coverage in Indonesia has fallen from around 30,000 km2 in 1994 to about 8,000 km2 today, with losses driven by pollution, mining, coastal development and sedimentation that reduces water clarity and habitat quality.
- Indonesia holds some of the world’s most extensive remaining seagrass meadows, estimated to store more than 30 million metric tons of CO2, making their protection crucial for both national and global climate goals.
- Scientists and conservation leaders urged stronger data collection, funding and institutional capacity to support restoration, monitoring and community participation, positioning Indonesia as a potential leader in seagrass conservation.
Chaos on Cambodia’s Coast
Along Cambodia’s rapidly transforming coastline, illegal trawling, elite-backed development, and weak enforcement are driving marine ecosystems and fishing communities to the brink. This 2024 series investigates the institutional breakdown behind the country’s marine crisis, from ineffective patrols in protected areas to billion-dollar land deals displacing small-scale fishers. It examines the competing interests reshaping Cambodia’s coast, […]
Scientists map Italy’s entire coast to guide seagrass and marine recovery
- Posidonia oceanica is a Mediterranean seagrass whose meadows act as a carbon sink, a coastal protector and a nursery for marine life.
- This ecosystem is under severe threat from human activities, including illegal trawling, pollution and boat anchoring, resulting in significant degradation and loss of biodiversity.
- Italy is employing sophisticated sensors to create an unprecedentedly detailed and comprehensive map of its entire coastline, including its Posidonia meadows, in an effort to improve management and conservation of its marine habitats.
- While large-scale mapping provides the blueprint, targeted protection and restoration efforts demonstrate that it’s possible to reverse the damage and bring life back to the sea.
‘A very successful story’: An Egypt tribe welcomes tourists & protects its coast
- Al-Qula’an is an “eco-village” in the Wadi El Gemal protected area in Egypt that environmentalists say is an example of how eco-tourism, along with traditional knowledge and practices, can help protect sensitive ecosystems.
- The mangroves of Al-Qula’an provide nursery grounds for marine species, and the coastal habitats serve as nesting sites for endangered sea turtles.
- The village has transformed from a subsistence fishing community to a low-impact eco-tourism destination while upholding principles of the Ababda tribe, like the importance of preserving mangroves.
Why is protecting this Honduran lagoon so dangerous?
LAGUNA DE LOS MICOS, Honduras — Tension swirls around the Laguna de los Micos in northern Honduras, which is a critical marine ecosystem surrounded by mangroves and serving as a home and nursery for many species of coral reef fish. The communities living around the lagoon have voluntarily agreed to suspend fishing for two months […]
Radar study shows when offshore turbines pose greatest risks to migrating birds
- A new study looks at bird migration patterns over open ocean in an attempt to assess how much risk offshore wind turbines and other marine infrastructure might pose to them.
- The authors used radar data from U.S. coastal weather stations to find that hundreds of millions of birds migrate over tight windows of time in the spring and fall while flying at slightly lower elevations on average than over land.
- This puts a proportion of them at risk of being killed by wind turbines, but that risk could be mitigated with dynamic management that accounts for their patterns, according to the study.
- The Trump administration, in office since January, says it doesn’t support offshore wind development, but the research has long-term implications and could be used more immediately for mitigating the impact of offshore oil and gas projects.
A protected mangrove forest stands strong as Metro Manila’s last coastal frontier
- A Ramsar site described as the Philippine capital region’s last remaining functional wetland, Las Piñas-Parañaque Wetland Park is a vital sanctuary for more than 160 local and migratory birds.
- The wetland also serves as a haven for fish reproduction, bolstering regional fisheries, and serves as a buffer zone during storms.
- In March, the agency responsible for overseeing investments in large-scale reclamation projects put out a call for “lease or joint venture” proposals for the site.
- After facing public backlash, the agency quietly deleted the call, saying it is aware of the site’s ecological importance and does not plan reclamation projects within the park.
Indonesia eyes seagrass zoning for blue carbon; experts urge community benefits
- Indonesia is moving to designate 17 seagrass habitats as national strategic areas for blue carbon, a plan that promises climate and community benefits but raises concerns over safeguards.
- The fisheries ministry says the zoning will help cut emissions, protect marine ecosystems and boost coastal livelihoods, with seagrass storing carbon far more effectively than rainforests.
- Experts welcome the initiative but warn it must avoid privatization, ensure fair benefit-sharing and guarantee transparent governance to prevent conflicts and elite capture.
- With Indonesia holding 11.5% of the world’s seagrass meadows, scientists stress the urgency of protection as the ecosystems vanish globally at alarming rates.
Northeast Pacific endures fourth-largest marine heat wave on record
The Northeast Pacific ocean, off the U.S. West Coast, is experiencing its fourth-largest marine heat wave since record-keeping began in 1982. “The extent of the current Pacific marine heatwave should be surprising … but unfortunately, record breaking heat is our new norm,” Chris Free, a marine scientist at the University of California, Santa Barbara, told […]
California’s kelp forests struggle to recover a decade after collapse
More than 10 years after unusually high water temperatures in the Pacific Ocean killed off Northern California’s aquatic kelp forests, the region has still not recovered, reports David Helvarg, executive director of ocean conservation group Blue Frontier, for Mongabay. From 2013 to 2017, a mass of unusually warm water nicknamed “the Blob” hugged California’s coast, […]
Panama upwelling fails in 2025, threatening marine ecosystems
Every year in the Gulf of Panama, between December and April, trade winds from the north push warm surface water away from the coast, allowing cool, nutrient-rich water from the depths to rise, in a process called upwelling. This is critical for the region’s marine life and fisheries. However, for the first time in at […]
Uruguay’s green hydrogen plans raise ecological concerns in Argentina & at home
- Communities in the Argentinian town of Colón worry that an upcoming major green hydrogen project on the Uruguay River will affect local ecosystems, as well as local tourism.
- The Paysandú e-fuels facility is one of Uruguay’s major hydrogen projects, as the country is pushing to further decarbonize its economy and boost hydrogen exports. The plant will produce green hydrogen using renewable energy to then produce e-methanol for exporting.
- Argentinian activists fear potential pollution from the plant and criticize the project for lack of transparency over its environmental impacts. Opposition is also growing on the Uruguayan side of the river.
- Another green hydrogen project in the town of Tambores is also being denounced for its impact on water resources, as the plant will withdraw large amounts of water from some of the country’s largest aquifers.
Indonesia’s giant Java seawall plan sparks criticism & calls for alternatives
- Indonesia has launched a massive new project on Java’s northern coast, framed as protection for millions of residents from worsening environmental threats.
- The plan has drawn sharp criticism from experts and activists who question its methods, costs and potential impact on vulnerable communities.
- Calls are growing for deeper public consultation and long-term solutions that go beyond quick fixes.
Death of activist critical of geothermal project raises alarm in Indonesia
- Vian Ruma, a 30-year-old opponent of a geothermal project on Flores Island, was found dead under circumstances his family and allies say point to foul play.
- His death highlights Indonesia’s long and worsening record of attacks on environmental defenders, with activists saying most violence and killings of activists in the past decade have targeted this group.
- Under President Prabowo Subianto, cases of threats and attacks on environmental human rights defenders have more than doubled in early 2025 compared to the same period last year.
- Police and companies increasingly use criminal charges to silence critics, deepening fears among civil society of shrinking space to call out environmental violations.
Post-Blob, California’s kelp crisis isn’t going away
- Kelp forests function as major habitat for marine biodiversity, but are in rapid decline worldwide, largely because of climate impacts on the oceans.
- A 2013 marine heat wave known as “the Blob,” combined with the mass die-off of sea stars, caused a 95% loss of Northern California’s kelp forests.
- The loss of sea stars allowed the purple urchins that they thrive on to spread rapidly, converting lush kelp forests into “urchin barrens” in parts of California. There’s been very little recovery since.
- Restoration of kelp forests is extremely difficult and requires far more resources than are currently being committed.
Cruise industry expansion collides with Cozumel’s coral reef
- Mexico’s Cozumel Island is one of the most popular cruise ship destinations in the world, hosting more than 4.5 million tourists every year.
- A plan to build a new pier for cruise ships has attracted concern from Cozumel residents and conservationists, who say it will damage the surrounding reef and block public access to the sea.
- The company behind the project, Muelles del Caribe, maintains the pier will bring financial benefits to the community.
- Conservationists assert that the project’s environmental impact assessment was insufficient; in July, a court ordered a temporary suspension of the project to allow for a more thorough environmental assessment.
Indonesia’s fish farm expansion to absorb D.C.-sized swath of protected forests
- This year, Indonesia’s government announced the first stage of a five-year plan to expand and intensify aquaculture production on 78,000 hectares (193,000 acres) along the north coast of Java Island.
- The first phase, 20,400 hectares (50,400 acres), will cover four districts in West Java province.
- Civil society leaders in Indonesia point to problematic experiences with similar “strategic” projects administered by the central government, adding that the initial plan in West Java risks further diminishing local fishers’ standing, rather than stimulating the community economy.
- A review of zoning documents by Indonesian environment watchdog Walhi showed the initial stage in West Java would include reclassifying 16,078 hectares (39,730 acres) of protected forests for the project — an area nearly the size of Washington, D.C.
Brazil cities order endangered angelshark meat despite fishing ban
Government agencies in Brazil’s Rio Grande do Sul state launched public procurements for more than 200 metric tons of meat from endangered angelshark species between 2015 and 2025, a Mongabay investigation has revealed. The meat is served in public institutions, including schools. Fishing for angelsharks is prohibited in Brazil, but its trade is legal if […]
Philippine fishers struggle as LNG ‘superhighway’ cuts through biodiversity hotspot
Fishers in the Philippines’ Batangas Bay are struggling to make ends meet and feed their families as nearby coastal areas are developed into a natural gas import hub, Mongabay contributor Nick Aspinwall reported in July. Families that have been fishing in Batangas Bay for years have been asked by local officials to leave to make […]
Indonesia’s aquafarm revamp sparks fears for fate of farmers and mangroves
- Indonesia plans to revitalize 78,000 hectares (193,000 acres) of state-owned aquaculture ponds, starting with 20,400 hectares (50,400 acres) in West Java province, aiming to boost yields, create 119,000 jobs and attract investors.
- Small-scale farmers like Warno in Karawang district, who rent and maintain ponds from the state, say they fear losing their livelihoods without compensation if the government takes over their farms.
- NGOs and experts warn the program could fuel mangrove clearing, coastal damage and privatization of coastal areas, while sidelining local communities’ rights and voices.
- Critics also raise concerns over the government’s push for more farming of saltwater tilapia, citing risks from the invasive species and an industrial aquaculture model that could reduce locals to laborers.
A critical stopover for shorebirds awaits protection in Malaysia
- Malaysia’s Teluk Air Tawar-Kuala Muda (TAT-KM) mudflats host tens of thousands of migratory birds along the East Asian-Australasian Flyway, including at one point the critically endangered spoon-billed sandpiper, yet remain outside formal protection despite global population declines from habitat loss.
- A recent study found only 15% of the sandpiper’s suitable non-breeding habitat is protected, with threats from coastal reclamation, invasive plants and sea-level rise; scientists call for prioritizing high-threat wintering areas, especially in Thailand and Myanmar.
- Malaysian authorities plan to nominate TAT-KM as an East Asian-Australasian Flyway Partnership (EAAFP) site, which would be a first for Peninsular Malaysia, but the process requires local stakeholder support and faces lingering concerns over past proposals for aquaculture development in the area.
- Local fishers, NGOs and conservation groups are raising awareness, restoring habitats and promoting bird-watching to safeguard TAT-KM, amid fears that without formal recognition, development pressures could threaten the ecosystem’s integrity.
Sri Lanka plans restoring revoked protection for an important mangrove patch in the island’s North
- In 2024, the Sri Lankan government revoked the protected status of an ecologically important mangrove forest in Vidattaltivu, in the island’s north, to facilitate the development of an aquaculture park.
- Environmental groups challenged the decision in court, calling for reinstatement of its former conservation status, following which the government informed the court of its willingness to restore protection.
- On July 26 this year, to mark World Mangrove Day, Sri Lanka declared several new mangrove areas protected, reinforcing its global recognition as the Commonwealth mangrove “champion.”
- The Indian Ocean island has approximately 15,670 hectares (38,720 acres) of mangroves, with around 60% under formal protection. However, enforcement and effective management remain weak in many areas.
‘Nothing about us without us’: Inuit leader Sara Olsvig on ocean politics
- Sara Olsvig chairs the Inuit Circumpolar Council (ICC), which represents some 180,000 Inuit people across Alaska (in the United States), Canada, Kalaallit Nunaat (the Inuit name for Greenland) and Chukotka (in Russia).
- Climate change has reduced the extent of sea ice in the Arctic Ocean, opening up new shipping lanes and increasing interest in various forms of resource exploitation, including for oil, gas and minerals.
- The ICC is engaged in negotiations over the development and implementation of major international agreements on shipping, plastics, and the management of biodiversity in the high seas, all under United Nations bodies.
- In all of these forums, the ICC is pushing for input into international rules that affect Inuit livelihoods and the Arctic environment.
As gas giants move in, Philippine fishers fight for their seas and survival
- Fishing communities along the Philippines’ Verde Island Passage, a haven for marine biodiversity, say the development of a natural gas import hub in the area is leading to environmental degradation.
- Fishers say their catches have declined since a liquefied natural gas plant was built in the area a decade ago, and that they’re being turned away from remaining fishing grounds due to the ongoing construction of an LNG terminal.
- The Japan Bank for International Cooperation, a key funder of the LNG project, denies these claims, saying in a recent report that it didn’t find evidence that LNG development had led to environmental degradation or a reduction in income for local fishing communities.
Photos: Mangrove photography awards showcase a diverse & fragile ecosystem

The contest, hosted by the U.S.-based Mangrove Action Project, showcases powerful photographic narratives highlighting the importance of one of the planet’s most vital ecosystems. This year, a record-breaking 3,300 entries from 78 countries entered to win in one of six categories: wildlife, […]
Batang coal plant’s seawater permit imperils marine life, fishing communities
- The Batang coal-fired power plant in Central Java, now legally permitted to use vast amounts of seawater for cooling, has raised alarms among experts over its impact on marine ecosystems and traditional fisheries.
- Since operations began, the plant has displaced fishing communities, polluted coastal waters with heated discharge and caused up to a 50% decline in shrimp catches, particularly affecting traditional fishers in Roban Barat.
- Community resistance was met with intimidation and arrests, while some residents accepted compensation from the operator, PT Bhimasena Power Indonesia, further dividing the local population.
- Critics, including Greenpeace and KIARA, say the project reflects Indonesia’s coal-centered energy policy, undermining both environmental justice and climate goals, as the country continues to expand fossil fuel use despite international pressure to shift toward renewables.
Reversing damage to the world’s mangrove forests
Mangroves are an important lifeline for biodiversity, climate and coastal communities. Yet they are disappearing 3-5 times faster than total global forest losses, according to UNESCO. On July 26, celebrated as the International Day for the Conservation of the Mangrove Ecosystem, we present recent stories by Mongabay’s journalists on emerging threats to these critical ecosystems […]
Sri Lanka hit by plastic pollution after cargo ship sinks off Indian coast
Sri Lankan authorities, locals and environmentalists say they’re deeply concerned about the possible impacts on the country’s marine ecosystem and coastal communities from the sinking of a container ship off the southern coast of India in May, Mongabay contributor Malaka Rodrigo reported in June. The Liberia-flagged ship MSC Elsa 3 sank on May 25 about […]
Blue carbon ecosystems are key for protecting the Philippines from climate shocks (commentary)
- In the wake of historic typhoon activity in 2024, members of the Zoological Society of London (ZSL) and others are calling for scaled-up coordination and action to safeguard blue carbon ecosystems that increase local capacity to recover from climactic shocks.
- Community-led projects that offer opportunities to increase investment and bring security back to local communities like mangrove forest restoration are one key example of a blue carbon initiative that the National Blue Carbon Action Partnership (NBCAP) is implementing with the support of ZSL.
- “Coordinated action by NBCAP will enable these ecosystems to come to life, delivering both protection and income for coastal communities,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
How much does it cost to restore a mangrove forest?
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Mangroves, the amphibious forests that fringe tropical and subtropical coastlines, are ecological powerhouses. They buffer communities against storm surges, support fisheries, and sequester carbon at rates that rival their terrestrial counterparts. Yet despite growing recognition of their value, […]
Indonesia moves to revise sea sand export policy after court ruling
- Indonesia’s Supreme Court earlier this year struck down key parts of a 2023 regulation allowing sea sand exports, citing legal contradictions and environmental risks.
- The annulled policy had reversed a two-decade ban and faced backlash for potentially harming marine ecosystems and coastal communities.
- The government now says it’s revising the regulation, arguing that dredging can benefit ocean health and support domestic infrastructure projects.
- Critics warn the practice threatens fisheries, marine carbon stores and long-term sustainability, and call for a shift toward restoration over exploitation.
Locals fear Chile’s new port project for green energy will disrupt ecosystems
- A new private port for public use near Punta Arenas, a city in southern Chile’s Magallanes and Chilean Antarctic Region, has been approved for multipurpose services, such as the development of green hydrogen and salmon industries.
- The region has recently attracted a lot of attention due to its enormous green energy potential.
- The company concerned told Mongabay that this port will reduce the need for developers of green hydrogen and other projects in the region to build their own private ports as there is currently a limited capacity.
- Environmental organizations and local residents fear the port’s construction and operations will impact marine ecosystems and boost industries that will likely cause greater environmental impacts, such as contamination from salmon farms.
Oil and plastic pollution from shipwreck raises concerns, legal scrutiny in India
- The MSC ELSA-3 shipwreck, off Kerala’s coast in southern India, spilled oil and plastic pellets, with potential impacts on marine life, coastal ecosystems and fishing livelihoods.
- Gaps in maritime law and weak enforcement leave India ill-equipped to handle plastic spills and wreck removal.
- Experts call for stronger spill protocols, legal updates, transparent cargo data and long-term ecological monitoring.
Out-of-range albatross makes a highlight in the revival of seabird watching in Sri Lanka
- Sri Lanka has recorded over 50 species of seabirds — birds that spend much of their lives at sea — within its territorial waters, including several long-distance migratory birds that travel thousands of kilometers across oceans.
- As observation of seabirds is challenging, only a small group of Sri Lankan birders have focused on this unique group. In the past decade, seabird studies in the island have seen a notable revival, led by enthusiastic young birders.
- Among last year’s remarkable observations is the sighting of a grey-headed albatross off Sri Lanka’s northern coast, marking the first-ever record of the species north of the equator, well beyond its usual Southern Ocean range near Antarctica.
- World Seabird Day, observed every year on July 3, commemorates the tragic extinction of the great auk, marking the last known pair of which was killed on that day in 1844 and highlighting the vulnerability of seabirds and the urgent need for their conservation.
Listings of Indonesian islands renew fears of privatization for coastal communities
- Listings of Indonesian islands on a foreign real estate site have sparked concerns about privatization, prompting the government to block the site domestically and clarify that islands cannot be sold to foreign entities under national law.
- Officials said the listings were likely aimed at attracting investment, not outright sales, but critics warn such practices enable control over island and offshore areas, often displacing fishers and triggering land conflicts.
- A 2021 regulation allows foreign investors to lease small islands for up to $1,900 per km² per year, and a government portal launched in 2024 streamlines permits for islands smaller than 2,000 km², accelerating commercialization.
- Watchdogs say 254 small islands have already been privatized, often without adequate oversight, and warn that unchecked investment could jeopardize fisher livelihoods and national sovereignty over maritime territories.
As Thailand’s fishing cats face habitat loss & conflict, experts seek resolution
- Fishing cats have lost vast swathes of their former range in Thailand, where decades of wetland conversion to fish farms, shrimp ponds and plantations have decimated their numbers.
- With habitats shrinking, these wild cats have been driven to living in human-dominated landscapes, where conflicts often arise.
- Fishing cats perceived as competing with farmers for fish and chickens are sometimes killed in retaliation.
- Activists and NGOs are working to reduce these conflicts and encourage landowners to preserve patches of remaining habitat suitable for the cats.
A Kenya marine biodiversity credit program restores mangroves — and livelihoods
- The decline of mangroves significantly weakens Kenya’s coastal protection, leaving shorelines susceptible to erosion, storm surges and rising sea levels, disrupting marine ecosystems, depleting fish stocks, leading to reduced biodiversity — and lost livelihoods for locals.
- A U.S.-based organization called Seatrees is working with the local Community Based Environmental Conservation (COBEC) and residents of Marereni to restore and protect coastal and marine ecosystems as a natural solution to climate change.
- Since 2024, Seatrees has offered donors the option of buying $3 “biodiversity blocks,” each of which represents a single tangible conservation action: planting one mangrove tree on site in Marereni.
- The work goes beyond just planting trees, as community members turn mangrove restoration into a livelihood by establishing and maintaining nurseries — and, in some cases, starting side businesses with the income.
Plastic bag bans linked to sharp decline in coastal litter, study finds
A new study finds that regional plastic bag bans in the U.S. significantly reduce coastal plastic bag litter compared with areas without such policies. Single-use plastic bags are one of the most ubiquitous forms of plastic litter. They are rarely recycled and degrade quickly into microplastics that are often ingested by wildlife, leading to injury, […]
As a fishing port rises in Kenya, locals see threats to sea life, livelihoods
- In Shimoni, Kenya, a new fishing port is slated to open in June.
- While the government promises local people opportunities for jobs and businesses once operations start, some residents foresee more harm than good from the port.
- Some conservation activities — including seagrass, coral and mangrove restoration projects as well as fishing, seaweed farming and tourism operations — have already suffered during the port’s construction phase, which began in 2022, local people say. They fear it may get worse once the port opens, especially if planned dredging proceeds.
- A county government official said Kwale county is monitoring the situation and pledged to mitigate any impacts and safeguard fishing activities and conservation efforts.
Seaweed farming as an eco-friendly alternative for Tanzanian fishing communities
Climate change, overfishing and habitat loss have caused a sharp decline in fish stocks around Pemba Island, off the coast of Tanzania. To find a new income from the sea, women from Pemba are turning to sustainable seaweed farming, Mongabay’s video team reported in May. Seaweed farming was introduced to the island in 1989. It […]
Major coral loss in Vietnam’s first marine protected area: Study
- Vietnam’s first marine protected area (MPA), Nha Trang Bay, has lost nearly 200 hectares (494 acres) of coral reef since it was established in 2002, according to a new study.
- Major drivers of the coral decline include coastal development, warming sea temperatures and devastating crown-of-thorns starfish (Acanthaster planci) outbreaks worsened by overfishing and nutrient pollution.
- The study calls for stronger conservation measures inside Nha Trang Bay and other MPAs, including pollution control, active reef restoration and inclusive community governance.
- Experts say Nha Trang Bay offers lessons for other MPAs in Southeast Asia facing similar threats.
Tanzania’s Mafia Island eyes sea cucumber farming to prevent extinction
Residents of Mafia Island in Tanzania don’t really eat sea cucumber; they call it jongoo bahari, or “ocean millipede” in Swahili. But sea cucumbers are a prized delicacy in East Asia, where demand has fueled a black market for the spiny sea creatures, Mongabay’s Ashoka Mukpo reported in May. A kilogram of dried sea cucumbers […]
UN Ocean Conference makes progress on protecting marine waters
- The United Nations Ocean Conference, held June 9-13 in Nice, France, saw some progress on better protecting the hundreds of thousands of species that live in marine waters and the communities that depend on the sea for work or sustenance.
- New countries committed to the high seas treaty, a moratorium on deep-sea mining and the World Trade Organization Agreement on Fisheries Subsidies, while a huge group of nations pushed for a strong global plastics treaty.
- Several countries also moved to create marine protected areas (MPAs) and reserves, or strengthen existing ones, including the announcement of the world’s largest MPA in French Polynesia.
- A wide range of groups announced other marine conservation initiatives.
Twin ship disasters in India threaten widespread pollution on Sri Lankan coasts
- The Liberia-flagged vessel MSC ELSA 3, carrying 640 containers, including 13 with hazardous cargo, along with almost 85 metric tons of diesel and 367 metric tons of furnace oil, sank off of Kerala, in southern India, on May 25.
- Just 10 days after the sinking of MSC ELSA 3, Sri Lanka’s northern coast recorded significant plastic pollution with the costal belt being contaminated with bags full of plastic nurdles, making the island nation brace for more pollution as strong monsoonal winds contribute to increased pollution.
- The incident has revived painful memories of 2021 when Sri Lanka experienced its worst maritime disaster, the X-Press Pearl incident, which caused massive coastal pollution on the island’s western coast and parts of the south and northwest, with the island nation still fighting for adequate compensation.
- Meanwhile, another ship, MV Wan Hai 503, carrying 2,128 metric tons of fuel and hazardous cargo, also caught fire on June 7, off the south Indian coast of Kerala, which is still ablaze and is expected to cause further pollution along Sri Lanka’s northern coast.
New study dismisses Amazon River runoff as primary cause of sargassum blooms
- Brazil’s northern beaches recently suffered from arrivals of sargassum blooms, a phenomenon affecting Caribbean nations that most scientists so far have associated with nutrients coming from the Amazon River plume into the Atlantic Ocean.
- A recent study suggests that ocean changes are the primary nutrient source for sargassum blooms since 2011, challenging previous hypotheses.
- Sargassum is causing considerable health and economic concerns as large amounts of this brown macroalgae arrive and accumulate in coastal ecosystems of western Africa and the greater Caribbean Sea every year.
- Brazilian authorities are learning from Caribbean countries how to manage sargassum blooms best, and experts think they should keep monitoring possible ocean current changes.
One-two punch for mangroves as seas rise and cyclones intensify
- More than half of mangroves worldwide may face high or severe risk by 2100 due to increased tropical cyclones and sea level rise, with experts predicting Southeast Asia to be hardest hit under all emissions scenarios.
- A new risk index combines multiple climate stressors — cyclones and sea level rise — with ecosystem service value, providing a novel, globally scalable tool for risk assessment and conservation planning.
- Mangrove loss has major human and economic costs, jeopardizing flood protection worth $65 billion annually and threatening 775 million people dependent on coastal ecosystems.
- Urgent, dynamic conservation and emissions cuts are essential; restoring degraded areas, enabling inland migration, and reducing emissions could significantly reduce risk and buy adaptation time.
Samoa’s new marine spatial plan protects 30% of the country’s ocean
- The Samoan government announced June 3 that it has enacted a law establishing a marine spatial plan to sustainably manage 100% of its ocean by 2030.
- The country has also created nine new marine protected areas that cover 30% of its ocean.
- Fishing is prohibited in the new protected areas, which include a migration route for humpback whales.
- The plan became law on May 1.
From local planting to national plan, Belize bets on mangrove recovery
- Mangroves in Belize protect coastlines, are nursery grounds for fish, and store vast amounts of carbon.
- In 2021, the government of Belize committed to restoring 4,000 hectares (nearly 10,000 acres) of mangroves, and protecting an additional 12,000 hectares (nearly 30,000 acres) within a decade, as part of its emissions reduction target under the Paris climate agreement.
- To support this restoration target, WWF Mesoamerica is developing a national mangrove restoration action plan.
- Restoration initiatives are already underway in areas like Gales Point, Placencia Caye and elsewhere.
Guinea-Bissau’s grassroots efforts offer a blueprint for global mangrove restoration (commentary)
- Guinea-Bissau’s mangroves have declined by nearly a third over the past 80 years, but the country still has the largest mangrove area as a proportion of its total area in the world.
- A grassroots revolution is underway, spearheaded by national organizations, international partners and local communities to restore the country’s mangrove landscapes.
- Called Ecological Mangrove Restoration, this method focuses on optimizing conditions for the mangroves to restore naturally, as well as collaborating with communities to ensure sustainability and resilience by fostering ownership of the project while leveraging local knowledge and resources.

DNA probe links Japan’s otter-themed cafes to poaching hotspots in Thailand
- Asian small-clawed otters have long been taken from their wild habitats in Southeast Asia to supply the opaque and often illegal pet trade.
- Booming demand for captive otters, stoked by social media and TV shows, looks set to worsen amid an emerging trend for exotic animals cafes.
- A new genetic study links otters found in exotic animal cafes in Japan with wild populations in well-known poaching hotspots in southern Thailand.
- The new DNA evidence of a wildlife trade route between Thailand and Japan backs up calls from experts for stricter monitoring of wildlife exports from Thailand, as well as strengthened law enforcement and education in known poaching hotspots.
The blobby little sea squirt that stowed away across the Pacific to California
- In 2023, scientists found a nonnative species of marine invertebrate in a private marina near Los Angeles, California.
- The arrival of this new member of California’s marine fauna highlights the massive, largely uncontrolled movement of marine species via ships that travel the world.
- Concerned about potential ecological and economic impacts, the state of California has tried to curb the movement of nonnative marine species through regulations of large ships and commercial ports, but the regulations don’t apply to smaller vessels.
- Beginning in 2025, California will have to comply with less-stringent federal biofouling and ballast water regulations.
West Sulawesi erupts in protest over sand mining for Indonesia’s new capital
- Hundreds of protesters, including Indigenous and coastal youth from Karossa, Pasangkayu and Kalukku, rallied on May 5 at the West Sulawesi governor’s office to demand the closure of PT Alam Sumber Rezeki’s sand mining operations, citing environmental harm, permit irregularities and lack of community consent.
- Tensions flared after Governor Suhardi Duka dismissed anti-mining resistance as “thuggery,” triggering public outrage and a clash with security forces during the protest, where demonstrators were met with water cannons and no official response.
- The mining, tied to supplying materials for Indonesia’s new capital, Nusantara, has fueled a wider grassroots resistance across West Sulawesi, with activists condemning the criminalization of local opposition and calling for meaningful community involvement in environmental decision-making.
Angling for answers, this saltwater fishing group boosts research for better conservation
- Though anglers aren’t generally thought of as environmentalists, many people who fish are conservation minded, whether because it’s an outdoor pursuit, or because they wish to ensure future harvests.
- Whatever their reasons, there aren’t many groups that help anglers advocate for sustainable fishing regulations based on solid science, nor ones that also work to generate new data that helps them argue for better conservation.
- “Until we came along, there was no voice for those saltwater anglers who cared about conservation, but didn’t have enough time to put into it to really understand it,” says American Saltwater Guides Association vice president Tony Friedrich.
- His team not only helps its members articulate the need for conservation and regulation, they actively participate in developing data that helps managers set better limits, through projects like their GotOne App.
There’s something fishy about ‘blue economy’ proposals for sustainable marine management (commentary)
- Proposals for developing a “blue economy” emerged in the 2010s as a vision for sustainable ocean development, as communities across the world grappled with challenges of declining ocean health, economic crises and stalling development outcomes.
- Central to their appeal is a promise to transform human interactions with the ocean, promoting a shift toward ecological health, improved livelihoods and job creation, but too often these proposals have been driven by large nations and interests, rather than small coastal nations whose prosperity is most heavily linked with marine ecosystems.
- The author of this commentary warns that this sustainable ocean vision may be operating as a tool for pacifying demands for sustainable and equitable ocean relations, rather than as one that advances them.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Scientists warn of S. Korea airport project’s impact on migratory bird habitat
Scientists have raised the alarm about biodiversity loss if construction of an airport near South Korea’s west coast begins as proposed this year. In an open letter published in the journal Science, they highlight the loss of migrating birds from the Sura area, the last remaining tidal flat within the once-thriving Saemangeum estuary, where saltwater […]
Protected parks in peril as Republic of Congo ramps up oil drilling
- The Republic of Congo plans to nearly double its oil production over the next three years, including drilling in protected areas like Conkouati-Douli National Park, sparking outrage from environmental activists and civil society groups.
- This expansion directly contradicts the country’s climate commitments made at the 2023 U.N. climate conference and its stated goals of preserving biodiversity.
- Major international oil companies — including TotalEnergies, Perenco, and Chinese firms — are supporting this fossil fuel push despite past pollution scandals and a lack of public environmental impact assessments.
- Critics also warn of systemic corruption and resource mismanagement, questioning whether the projected revenues will benefit the public as fuel shortages and extreme climate impacts continue to hit the country.
Building a future from seaweed in coastal Tanzania
PEMBA ISLAND — Tanzania. The coastal communities on Pemba Island, off the coast of Tanzania, have long depended on the rich marine resources of the Indian Ocean. But in recent years, fish stocks have declined due to overfishing, habitat loss, and the impacts of climate change. Many have had to seek new ways to earn […]
Protecting coastal waters may be the best investment you’ve never heard of, says Kristin Rechberger
- In this interview, Kristin Rechberger—founder of Dynamic Planet and a Mongabay board member—discusses Revive Our Ocean, a new initiative empowering coastal communities to establish marine protected areas (MPAs) that benefit both nature and livelihoods.
- With only 3% of the ocean fully protected and the 2030 “30×30” target looming, Rechberger argues that waiting on governments isn’t enough; community-led efforts are crucial to scaling marine conservation rapidly and equitably.
- Drawing on a decade of experience creating large offshore marine reserves, Rechberger is now focusing on coastal regions where local communities have a direct stake in healthy seas—but often lack the legal authority, tools, or support to act.
- She emphasizes that marine protection is not only ecologically effective but economically smart, citing examples like Spain’s Medes Islands Reserve and Mexico’s booming dive tourism as models for prosperity through conservation.
‘We belong to one ocean’: Indigenous leaders push for seat at the table of high seas biodiversity treaty
- Members of Indigenous peoples and coastal communities convened at the United Nations Permanent Forum on Indigenous Issues to call for their inclusion in the Agreement on Marine Biodiversity of Areas Beyond National Jurisdiction (BBNJ), also known as the High Seas Treaty.
- These are the first-ever calls by Indigenous and coastal communities as members attending the forum prepare for the entry into force of the BBNJ agreement.
- Their participation could include involvement in governance, environmental management, and best-practice strategies based on traditional ecological knowledge and values.
- The BBNJ agreement will enter into force once at least 60 countries ratify it. So far, 113 countries have signed the agreement, while 19 have ratified the treaty.

Mongabay’s Leo Plunkett and Sandy Watt report in a recent Mongabay video that the newly created marsh has brought a host of benefits to the region. The Steart […]
‘It has been worth it’: The local women saving Yucatán’s mangroves
- Mangrove forests provide important ecosystem services, from acting as nurseries for fish to buffering coasts from storms.
- Mangroves along the northern coast of the Mexican state of Yucatán have been impacted by deforestation and highway and port development.
- A group of women called Las Chelemeras has for the past 15 years worked to restore the region’s mangrove forests and ecosystem function.
- Their restoration tasks involve opening and maintaining channels so that water can infiltrate and drain with the tides, and planting mangrove tree seedlings.
Mangroves mount a fragile green revival in Iraq’s toxic south
- Sea-level rise and upstream damming have worsened saltwater intrusion in the Shatt al-Arab River, pushing brine deep into Iraq’s interior and threatening agriculture, fishing and marshland ecosystems.
- A mangrove-planting project has been launched as a nature-based solution to combat coastal erosion, saltwater intrusion and pollution — threats that not only endanger Basra’s coastline but also the freshwater marshlands farther inland.
- Despite scientific backing and community support, the project faces significant obstacles like untreated sewage and industrial waste, while limited government support further hampers the project’s long-term viability and impact.
Award-winning film highlights lasting damage from X-Press Pearl disaster in Sri Lanka
- “This Is Not a Pearl,” a short film by Sri Lankan filmmaker Tharindu Ramanayaka, uses a poetic narrative of a pearl oyster mistaking toxic plastic pellets, or nurdles, for her pearl to symbolize the environmental devastation caused by the 2021 MV X-Press Pearl disaster.
- The sinking of the MV X-Press Pearl off Sri Lanka’s coast released 1,680 metric tons of plastic nurdles, marking the world’s largest nurdle spill and triggering long-term damage to marine ecosystems.
- Scientific studies show that toxic chemicals from the spill continue to harm marine life, especially zooplankton like sea urchin larvae and copepods, threatening the broader ocean food web.
- Sri Lanka’s legal efforts for compensation, including cases in both Singapore, where the ship’s operator is based, and the Sri Lankan Supreme Court, remain unresolved; meanwhile, nurdles continue to wash ashore, requiring continuous cleanup efforts nearly four years later.
Dugong numbers plummet amid seagrass decline in Thailand’s Andaman Sea
- Thailand’s dugongs are disappearing fast, reflecting an unfolding crisis in the region’s seagrass ecosystems.
- Seagrass beds on Thailand’s Andaman Sea coast that support one of the world’s most significant populations of dugongs have died off in recent years, creating an increasingly challenging environment for the charismatic marine mammals.
- Scientists point to a combination unsustainable coastal practices and climate change as the main factors driving the decline.
- Government agencies, marine scientists and volunteers are taking emergency steps to save the remaining dugongs, but experts warn their long-term survival in Thailand depends on fixing the root causes of the seagrass loss.
As Acapulco’s mangroves disappear, Mexico takes strides to protect its coastal forests
- One of Acapulco’s lagoons has experienced the near-complete loss of its mangroves due to urbanization and hurricanes.
- Another Acapulco lagoon has also lost portions of its mangroves, affecting the local fishing industry.
- Overall, the Mexican state of Guerrero has lost more than half of its mangroves since 1979.
- Mexico’s government is working with international organizations, scientists and local communities to restore the country’s lost mangroves.
Bangladesh witnesses coastal erosion, salinization as tourism crushes a flowering creeper
- Bangladesh’s sandy beaches have been witnessing the disappearance of a once-common flowering vine, the beach morning glory, especially on Cox’s Bazar beach.
- Seashore erosion is now increasing in the region as this plant is supposed to retain soil and protect the beach from erosion.
- Experts and studies indicate the excessive and unchecked tourism in the coastal district as one of the major reasons for this loss.
Peruvian fishers sue for additional compensation after big December oil spill
- On Dec. 22, 2024, a pipeline leak at the New Talara Refinery in northern Peru spilled oil into the Pacific Ocean, coating 10 kilometers (6 miles) of coastline in black.
- Three days later, the Peruvian environment ministry declared a 90-day environmental emergency, paralyzing tourism and work for more than 4,000 artisanal fishers.
- Now, more than three months later, the fishers have returned to work on a sea dominated by the oil industry. They say the compensation they received from the refinery owner, state-owned oil company Petroperú, is insufficient and they are seeking more.
- For its part, the company says it has met its commitments.
Colombia’s women clam collectors protect Pacific mangroves and mollusks
- Along Colombia’s Pacific coast, women belonging to the Afro-Colombian community who harvest piangüa mollusks have united in efforts to conserve these small, black-shelled clams.
- For generations, piangüa collecting has been their livelihood, a nutrient-rich food source and important symbol of cultural heritage.
- But piangüa populations have diminished in recent years, due to commercialization and overharvesting as well as exports to Ecuador.
- The women piangüeras monitor the local mangroves, crucial to piangüa conservation, and when they observe signs of human disturbance or logging, they encourage people to leave the area alone during “rest periods” so the mangroves can recover.
In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.
Why are the British flooding parts of their coast?
SOMERSET, England — Steart Marshes, in southwest England, may not be the most picturesque nature reserve in the British Isles, but it is undoubtedly one of the most fascinating. Just over a decade ago, this landscape was farmland, but its precarious position, wedged between the River Parrett and the Bristol Channel, made it highly vulnerable […]
Planned port project threatens protected Amazonian mangrove biodiversity and local livelihoods
- The proposed Alcântara Port Terminal in Brazil’s northeastern state of Maranhão is set to be constructed within the Reentrâncias Maranhenses, a protected mangrove area and Ramsar site on the Amazonian coast.
- Researchers and local Quilombola residents fear the port will impact the area’s protected wetlands and cause a disturbance to breeding bird colonies and marine species.
- The construction of the port will destroy several freshwater lagoons found within the island, sea turtle nesting grounds, and the fishing areas of the local communities.
Sri Lanka communities left gasping for climate mitigation support
- Despite being highly vulnerable to climate risk, Sri Lanka is slow to tap into climate funding due to a range of issues including inadequate data systems, institutional weaknesses and limited capacity to design and implement viable projects.
- Sri Lanka’s disaster management units require significant funding to initiate mitigation measures amid increasing climate change impacts, where the most vulnerable populations bear the brunt of climate impacts.
- The island’s nationally determined contributions (NDCs) are still to be submitted, adding to delays in pursuing climate finance opportunities for Sri Lanka.
- With many people vulnerable to climate change impacts and lacking adaptive capacity, building resilience calls for much higher financial investments in climate adaptation.
Mangroves at risk as El Salvador begins work on new airport
- Officials broke ground last week on the Airport of the Pacific near the coastal town of La Unión, in eastern El Salvador, where mangrove ecosystems support wildlife and prevent coastal erosion.
- While the project could bring thousands of jobs to an undeveloped part of the country, it could also lead to massive development where coastal habitats currently protect drinking water for local communities.
- The airport is part of President Nayib Bukele’s plan to invest over a billion dollars into the eastern side of the country.
From Kenya to Madagascar, massive effort aims to put seagrasses on the map
In 2019, scientists set out to map the extent of seagrass in Seychelles, an island nation off the eastern coast of Africa. There, they hit upon a startling number: More than 90% of the country’s “blue carbon,” or the carbon stored in marine ecosystems, is contained within seagrass meadows. Under the Large-scale Seagrass Mapping and […]
Illegal sea fence displaces fishers and sparks land scandal near Jakarta
- A property developer installed 30 kilometers (19 miles) of bamboo fencing in the sea near Jakarta, blocking fishers’ access; an investigation revealed it encompassed 280 ocean plots for which title deeds had been illegally issued.
- The fence has forced many fishers to stop working, while coastal farmers have lost their land to the same luxury development; residents also face eviction with no clear alternatives.
- Authorities have sanctioned a handful of individuals from the public and private sectors and started revoking the illegal deeds, but activists are demanding criminal prosecutions against the companies responsible.
- The case highlights weak oversight of Indonesia’s national strategic projects, raising concerns over environmental destruction, loss of livelihoods, and government favoritism toward big developers.
Mangrove deforestation for commodities limits conservation funding in SE Asia
- Southeast Asia’s mangrove forests are still at risk of conversion for oil palm, rice and aquaculture, despite their immense potential for mitigating global biodiversity and climate goals.
- Commodity-driven deforestation and a range of climate change-related risks threaten the long-term survival of 85% of the region’s mangrove forests that could feasibly host carbon credit projects, a new study finds.
- The long-term risks undermine the integrity of blue carbon credits as a potential source of much-needed conservation funding, the study says, ultimately jeopardizing the capacity of mangroves to sequester carbon and provide ecosystem benefits.
- The authors recommend a diverse suite of conservation funding mechanisms rather than relying solely on blue carbon credits, and also urge greater investments in community-led mangrove initiatives.
Conservationists suspect fishing nets, increased tourism for sea turtle deaths in Bangladesh
- More than 100 olive ridley turtles were found dead in Bangladesh’s Cox’s Bazar Beach in the last few weeks.
- Conservationists blame the uncontrolled use of fishing nets and increased tourism during the turtle nesting period to have played a key role in the incident.
- The olive ridley’s main nesting grounds are the various islands in the southeastern district, Cox’s Bazar in the Bay of Bengal, and they come to the beaches to lay eggs before returning to the sea.
- Over the last three years, Bangladesh saw there was an increased number of olive ridley turtles and hatchlings thanks to different conservation programs.
Illegal seabed dredging surges as Indonesia resumes sand exports
- Reports of unauthorized seabed dredging have surged following Indonesia’s decision to resume sea sand exports in 2023, raising environmental concerns and exposing weak marine law enforcement.
- Officials argue that removing sediment helps ocean health and prevents land buildup, but experts and activists warn the policy contradicts marine conservation efforts and lacks transparency.
- Dredging threatens mangroves, coral reefs, and fish populations, with projected losses to fishing communities far outweighing state revenue and corporate profits.
- Experts urge the government to reinstate the export ban, conduct thorough environmental impact assessments, and allocate funds for ecological restoration and affected communities.
Protecting peatlands and mangroves could halve Southeast Asia’s land-use emissions
- Protecting and restoring peatlands and mangroves across Southeast Asia could cut regional land-use emissions by half, equivalent to 16% of global land-use emissions, according to a new study.
- It found that rewetting 5.34 million hectares (13.4 million acres) of drained peatlands, along with restoring degraded peat swamp forests and mangroves, could significantly enhance carbon sequestration, with Indonesia having the highest mitigation potential.
- Southeast Asia lost 41% of its peat swamp forests and 7.4% of its mangroves from 2001 to 2022, largely due to plantations and aquaculture, contributing 691.8 million metric tons of CO2 annually, with peatland burning alone accounting for up to 20% of emissions.
- The study underscores conservation and restoration as cost-effective climate solutions capable of drastically reducing national emissions, and calls on governments to integrate these efforts into their climate strategies to meet and enhance their Paris Agreement commitments.
The world’s kelp needs help — less than 2% is highly protected
- Kelp forests support a kaleidoscope of biodiversity and perform crucial ecosystem functions, yet they are in trouble globally.
- A recent journal commentary shows that just 15.9% of kelp forests are in protected areas, and only 1.6% of them are in areas with the highest levels of protection.
- The authors said they hope their findings will motivate policymakers to include kelp forests in international conservation targets, such as the “30×30” mandate to protect 30% of Earth’s land and sea by 2030.
Better government policies could help as migratory birds lose habitat in Bangladesh
- Recent studies indicate a steady decline in the number of migratory water birds in Bangladesh over the last few years.
- Researchers said the key threats to migratory birds include habitat loss, cattle grazing in bird habitats, domestic duck farming and conservation mismanagement.
- They underscore the need for a coordinated effort among livestock, agriculture and environment ministries.
Mexican fishers relocate in wake of sea level rise, raising job concerns
- In the southern Mexican state of Tabasco, most residents of the El Bosque community have been relocated after their homes were destroyed by coastal erosion.
- Community members have expressed concern about job security, as the new site is 12 kilometers (7.4 miles) away from the sea and residents cannot as easily fish, which they depend on for their livelihoods.
- While planned relocation has emerged as a critical strategy to protect those impacted by climate change, reports have shown relocation does not always reduce socioeconomic pressures.
- Although fishers from El Bosque are concerned about the impact of the relocation on their livelihoods, some see it as an opportunity for younger generations to seek alternative livelihoods and better opportunities.
How to tell if mangrove restoration is working? Listen to the birds
- Mangrove restoration is often motivated by the desire to bring back biodiversity to degraded coastlines, but it’s difficult to know exactly when that objective has been achieved.
- Researchers in Malaysia say that monitoring mangrove-dwelling bird communities using bioacoustics could be a game-changer for managers tracking mangrove ecosystem recovery.
- Bioacoustics, the use of audio recording devices to listen to animals in their natural habitats, is increasingly being used as a rapid and relatively cost-effective way of measuring ecosystem health.
- The new study found bird species richness increases across a range of mangrove forest characteristics, including greater canopy cover, tree height and ground cover, indicating birds could serve as useful indicators of mangrove health.
Rail and port project in Amazon wetland stirs angst among Quilombola fishers
- Quilombos, rural settlements and environmental protection areas will be impacted by a new rail and port project in Brazil, according to Quilombola residents and a coalition of civil society organizations.
- They say the company did not consult all affected communities who depend on a wetland for fishing and called into question the validity of its environmental license.
- While some residents reject the project, the plans were approved by an association of residents of the rural Black Quilombola community in Cajual Island following promises of new housing, school and health centre, as well as 6% of profits.
- The project aims to transport iron ore extracted from Pará’s Carajás mine to China and European countries, as well as food and other commodities.

Lessons from successful mangrove forest restoration in El Salvador (analysis)
- Mangrove forests are important coastal ecosystems worldwide, and many areas that have suffered loss of these trees are the focus of restoration projects, but these suffer from a 70% failure rate.
- Not only are they key habitats for numerous organisms from crabs to fish and birds, they also supply a wealth of seafood for local communities.
- That makes community involvement a key aspect of the Community-Based Ecological Mangrove Restoration (CBEMR) method, which focuses on improving local hydrology and topography while removing or reducing mangrove stressors, and encouraging the trees’ natural regeneration.
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.
In Panama, major port construction begins at key mangrove site
- The Puerto Barú project, located outside the town of David in the Pacific province of Chiriquí, will be a new industrial port on Panama’s west coast, where channels and lagoons support mangroves, breeding grounds and nurseries for a variety of marine species.
- The project requires dredging a riverbed and increasing maritime traffic of cargo ships, cruise ships and yachts.
- More than 50 conservation groups have organized a “No to Puerto Barú” campaign, but an initial injunction to stop construction was shot down in court.
Ogoni women restore mangroves and livelihoods in oil-rich Niger Delta
- After decades of crude oil spills and the introduction of invasive plant species, thousands of hectares of mangroves in the Niger Delta are destroyed, impacting aquatic species and women’s livelihoods.
- Ogoni women from coastal villages, supported by the Lokiaka Community Development Centre, have been at the forefront of reforestation efforts.
- The women have planted 2.6 million mangrove trees since 2018, drawing attention from a government agency that hired them to share their knowledge and plant mangroves for its oil spill rehabilitation project.
- Around 300 women from Ogoni communities have been trained in mangrove reforestation.
‘LIFE’ scores map out where habitat loss for crops drives extinction
- Altering natural habitats for agriculture is the single biggest driver of extinctions.
- Land conversion is contributing to what scientists call Earth’s sixth mass extinction.
- Now, new maps link the conversion of landscapes to the risk of extinction for species; they also help identify places where restoration could increase the probability that species will survive.
- The tool works accurately on areas of land ranging from 0.5-1,000 km² (0.2-386 mi²), and could be used by consumers and conservation groups to identify key areas to prioritize for conservation or restoration.
By razing trees for flood defenses, a Philippine city may have raised its risk

- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Atlantic puffins are perilously attracted to artificial light
- When they make their first journey into the ocean, fledgling Atlantic puffins are prone to being stranded on land, imperiling them. For years, scientists have wondered what leads to these strandings.
- A new study provides experimental evidence to show that artificial light lures young puffins toward land, contributing to strandings.
- The study found pufflings don’t have a strong preference for any particular light source or color. However, once stranded, they move more under darkness and high-pressure sodium lights than under LED lights.
- Reducing artificial lights along the coast and offshore could save puffin lives, say conservationists, as Atlantic puffin populations are decreasing in parts of Europe. It can also save other threatened seabirds, such as Leach’s storm petrel found off Canada’s coast.
India’s latest forest cover report hints at countrywide degradation
The latest forest survey report from India suggests a slight increase in the country’s forest and tree cover in recent years. But experts say the net marginal gain masks considerable declines across many biodiversity-rich forests and mangroves as well as in overall forest quality, reports Mongabay India’s Kundan Pandey. The report, published by the Forest […]
After trial and error, Mexican fishers find key to reforesting a mangrove haven
- David Borbón and his community are working to restore mangroves in a fishing village within Mexico’s El Vizcaíno Biosphere Reserve, one of the country’s largest protected areas.
- The mangroves act as a natural barrier, protecting the coastal community and ecosystems from hurricanes and other severe weather.
- Borbón, who wasn’t formally educated in any science, conducted a series of experiments to find the best method to reforest the area’s declining mangrove forests and settled on a direct sowing technique that replicates natural patterns.
- With the support of his family and community, he has now planted more than 1.8 million mangroves and largely facilitate the recovery of the mangrove ecosystem.

Shipbreaking pollutes Türkiye’s coast despite European cleanup efforts
- Over the past decade, more than 2,000 ships have been dismantled at shipyards in Türkiye’s coastal town of Aliağa, one of the world’s main destinations for decommissioned vessels.
- Locals and environmentalists alike complain of rampant water and air pollution linked to shipbreaking, among other industrial activities.
- Workers’ unions and activists have also called out substandard working conditions at the yards, recording 11 deadly accidents between 2018 and 2024.
- Efforts by the European Union to promote better practices in some yards by allowing them to dismantle European ships have had a mixed effect, according to workers and experts Mongabay interviewed, encouraging some yards to improve practices without solving the pollution problem.
Communities warn of threat to ecosystems from Brazil bridge project
- 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.
Construction of Indonesia’s new capital sees port activity crowd out fishers
- 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.
How are mangrove restoration projects doing? Interview with Tom Worthington
- A new tool aims to help managers of mangrove restoration projects track their progress and measure final outcomes against initial goals.
- The Mangrove Restoration Tracker Tool was developed by the University of Cambridge, WWF and the Global Mangrove Alliance in a bid to streamline global data on mangrove restoration projects around the world.
- Mangroves are crucial ecosystems that serve as carbon sinks and act as a buffer against coastal erosion; however, they’re threatened by deforestation as well as by the impacts of global warming.
How a holistic approach aims to heal mangroves in Guinea-Bissau
- Though small, Guinea-Bissau has sizable amounts of mangroves, which cover 9% of this West African country.
- Farmers clear patches of mangroves to grow rice, but climate change and socio-economic shifts mean that many hectares of former rice fields lie abandoned, and could be restored.
- Wetlands International is using an approach called Community-based Ecological Mangrove Restoration (CBEMR) to regenerate abandoned rice fields in and around Cacheu and Cantanhez national parks; 2,600 hectares have been restored to date.
- Community involvement is a cornerstone of the approach, and the project also supports income generation and educational activities.
As Sumatra loses mangroves to oil palms, local fishers also suffer
- Interviews in Kwala Langkat, a fishing village in Indonesia’s Langkat district, along the Malacca Strait, suggest fisheries incomes have collapsed after local elites ripped out a mangrove ecosystem to establish a new oil palm plantation.
- In June, Mongabay reported that police had arrested three residents of Kwala Langkat village in connection with alleged criminal damage to a structure used on the oil palm plantation.
- More than a third of the world’s population today lives within 100 kilometers (60 miles) of the coast, a more than 50% increase in absolute terms compared with 30 years ago.
An ‘ocean grab’ for a property megaproject leaves Jakarta fishers grounded
- On the outskirts of Indonesia’s capital city, farming and fishing communities face displacement due to the planned construction of Pantai Indah Kapuk II, a vast complex of commercial property and mid-range apartments on the northeast coast of Jakarta’s metropolitan area.
- Farmers and fishers told Mongabay Indonesia that the developer had restricted their access to the sea, and acquired land without paying fair compensation for the value of productive trees.
- Indonesia’s fast-growing urban population has led to a housing crunch in several cities across the archipelago, with the national backlog estimated at more than 12 million homes.
- The national ombudsman’s office said no local residents had yet filed a report over land acquisition, while the developers did not respond to requests for comment.
Indonesia fisheries minister eyes aquaculture expansion under Prabowo
- Indonesia’s new president, Prabowo Subianto, has retained incumbent fisheries minister Sakti Wahyu Trenggono to oversee expansion in productivity in captive fisheries over the next five years.
- Sakti has pledged to revive ailing aquaculture ponds, most of which are located on the northern coast of Java, where numerous village fishing economies are struggling amid depleted near-shore fish stocks and coastal development.
- In July, Indonesia’s then-vice president, Ma’ruf Amin, told a fisheries summit that climate change, biodiversity loss and environmental damage had hindered the output of near-shore fisheries in the world’s largest archipelagic country.
Marshes are cost-effective for protecting coasts: Study
Climate change effects, including rising sea level and increasingly powerful storms, have put many coastal communities at risk. To mitigate damage, governments have responded by building higher seawalls. But a new study finds there is a more cost-effective, green solution: Instead of blocking water with walls alone, absorb it with marshes first. Previous studies suggest […]
Tiger population census in Bangladesh shows a hopeful upward trend in the Sundarbans
- The latest tiger population census in Bangladesh, which was done by evaluating camera-trapping data, shows that the country is home to at least 125 adult Bengal tigers.
- The report shows almost a 10% increase since the last census in 2018 in the Sundarbans mangrove forests, which is considered to be Bangladesh’s only remaining habitat for tigers.
- Conservationists attribute this success to the efforts made in the region in recent years, including installing fences and increased patrolling against poaching.
Thailand’s budding mangrove restoration plans spark both hope and concern
- Mangrove restoration projects based on mass tree planting have often proved unsuccessful due to a focus on quantity rather than carefully selecting planting sites or prioritizing long-term social and ecological gains.
- Thailand’s state-led and corporate-funded restoration approaches have typically followed this unsustainable model, prompting critics to call for more ecological and community-based approaches that place more emphasis on natural regeneration.
- Several new national initiatives aim to improve mangrove management in Thailand: A collaborative public-private program called the Thailand Mangrove Alliance aims to bring 30% of Thailand’s mangroves under effective management by 2030.
- However, a new carbon credits initiative that aims to link coastal communities with corporate partners has drawn widespread skepticism from environmental groups, who warn the scheme could effectively transform public forests into corporate lands.
The disappearing red ghost crabs of Cox’s Bazar, a conservation crisis in Bangladesh
- Cox’s Bazar Beach in southeast Bangladesh is known for its vibrant red crab population, which creates a stunning spectacle in the early mornings and late afternoons. However, this natural wonder is now threatened by human activities and environmental degradation.
- Red ghost crabs benefit coastal ecosystems by aerating sand and improving water infiltration, and also as prey species. Their decline threatens the ecosystem health.
- Researchers say a beach management plan is crucial for their protection and restoration. Protected areas like in Kuakata have shown effectiveness in conserving ghost crabs. Raising awareness among local communities is also crucial for successful conservation efforts in Bangladesh.
Javan fisherwomen lead fight against marine dredging amid fears of damage
- Fisherwomen on the north coast of Java Island are pushing back against plans to dredge sea sand for export, saying they fear it will worsen coastal erosion and harm marine ecosystems.
- Under a 2023 regulation, the government ended a 20-year ban on sea sand exports, sparking backlash despite claims that dredging will occur only in open waters.
- Communities in the north Java districts of Demak and Jepara, where fishing is the primary livelihood, say they are particularly concerned that dredging will severely disrupt their fishing grounds and harm their livelihoods.
- Experts also warn of long-term damage both to marine ecosystems and to the economy, including losses to fishers and the undermining of Indonesia’s marine carbon storage.
Coastal farmers in Bangladesh give up shrimp farming for agriculture to combat salinity
- The decades-long shrimp aquaculture on Bangladesh’s southwest coast, which negatively impacts the environment in many ways, including creating a freshwater crisis, is now losing its importance as the farmers are gradually inclining toward agriculture again.
- Increased salinity, both due to sea-level rise and diversion of the upstream flow of freshwater, and peer pressure had forced the coastal farmers to venture into shrimp cultivation about four decades ago.
- For the last couple of years, excessive salinity and repeated viral outbreaks in shrimp farms have pushed the farmers back to agro-based farming again.
- Crop diversification plays a positive role in addressing the changes; however, water shortage poses a big challenge in restoring agriculture.
Cambodian fishers-turned-citizen scientists monitor marine mammal deaths
- In Cambodia, the NGO Khmer Ocean Life has trained residents of coastal fishing communities about threats to marine mammals so they can participate in a citizen scientist network aimed at tracking bycatch and strandings.
- At least 10 species of marine mammals are commonly found in Cambodia, including dugongs (Dugong dugon), Indo-Pacific finless porpoises (Neophocaena phocaenoides), Indo-Pacific humpback dolphins (Sousa chinensis) and endangered Irrawaddy dolphins (Orcaella brevirostris); all of these species face an array of threats, including coastal development and unsustainable fishing practices.
- Bycatch is the biggest threat facing marine mammals globally, according Sarah Tubbs, Khmer Ocean Life’s co-founder and co-director, and coastal marine mammals face greater threats due to their proximity to fishing activities.
- Currently, data on marine mammal bycatch and strandings are lacking in Cambodia; the citizen scientist network will provide real-time insights into where bycatch mitigation efforts are most needed.
S. Korea dune merchant, 72, held over sand mining in Indonesia mangrove forest
- The enforcement arm of Indonesia’s environment ministry in September arrested a South Korean national for allegedly running an illegal sand-mining operation in a protected forest on the west coast of Sulawesi Island.
- Investigators are reviewing the suspect’s network in collaboration with a state agency that reviews financial transactions, but it’s not yet unclear whether the sand was sold locally or mined for export.
- In May this year, civil society groups criticized a policy by President Joko Widodo to reverse a two-decade ban on the export of sand dredged from the beaches of the world’s largest archipelagic country.
Amid haze of war, Lebanese activists helped turtle hatchlings journey to sea
- The sandy beaches of South Lebanon are a crucial nesting ground for sea turtles.
- This year, 2,500 sea turtle hatchlings safely reached the Mediterranean from Al-Mansouri Beach, a key nesting site near the city of Tyre, according to a volunteer group that has been tending the beach and its turtles for two decades.
- Despite the escalating conflict with Israel and the prevailing climate of fear, the volunteers continued their efforts to protect both the animals and the beach.
- On Sept. 23, the leader of the volunteer group told Mongabay she had to flee her home in Tyre after surviving several Israeli air strikes.
NGOs raise concerns over oil exploration in Republic of Congo national park
- NGOs are calling on the government of the Republic of Congo to revoke a permit allowing oil exploration in Conkouati-Douli National Park, the country’s most biodiverse area.
- They argue that oil exploration and exploitation will have a catastrophic impact on the park and local communities living in and around it.
- They also argue that the project runs counter to agreements reached with international donors to fund forest protection and breaks the Republic of Congo’s own environmental law.
Experts call for urgent action as invasive species threatens Brazil mangroves
- The Sonneratia apetala plant is native to India, Bangladesh, Sri Lanka and Myanmar, yet biologists have found hundreds of specimens permeating the mangroves in the south of Brazil.
- Researchers believe the seeds were transported on ships from China and released at the port just 2 kilometers (1.6 miles) from the mangroves, where they were carried in the currents and rapidly spread.
- Experts warn that S. apetala could have severe ecological impacts, including the loss of biodiversity as it outcompetes native plants; they also fear it might spread to other mangroves.
- Since May 2023, researchers have been advocating for the total eradication of S. apetala in Brazil. However, Brazilian authorities only announced last month that they would remove the species, and the details of how this will be done have not yet been specified.

JAKARTA — In 2023, environmental activist Daniel Frits Maurits Tangkilisan was sentenced to seven months in prison under Indonesia’s controversial online hate speech law. His crime? A Facebook post criticizing illegal shrimp farms operating within Karimunjawa National Park, a UNESCO Biosphere Reserve. Tangkilisan was part of the #SaveKarimunjawa movement, which aimed to expose the environmental […]
Wildlife-rich mangroves suffer as Indonesia ramps up construction of new capital
- The development of Indonesia’s new capital city on the island of Borneo has resulted in clearing of mangrove forests that are home to threatened wildlife such as proboscis monkeys and Irrawaddy dolphins.
- The government has repeatedly claimed that the Nusantara project will be “green,” but experts attribute the ongoing deforestation to a lack of planning by the developers.
- With around 3,900 proboscis monkeys, Balikpapan Bay is a stronghold for the endangered species; but the new capital city’s footprint overlaps with 41% of their habitat.
- The government agency overseeing the project insists it’s doing what it can to mitigate the impacts on wildlife and ecosystems through planning, as well as cracking down on contractors destroying the mangroves.
Not merely ‘exploration’: PNG deep-sea mining riles critics & surprises officials
- Deep Sea Mining Finance (DSMF), an obscure company registered in the British Virgin Islands, recently conducted an exploratory mining operation off the coast of New Ireland province in Papua New Guinea (PNG), according to civil society members and a government official’s statements to the media.
- Satellite-based vessel-tracking data show that much of this mining activity took place in and around a controversial project site known as Solwara 1, where mineral-rich hydrothermal vents are located.
- Critics say the operation was illegal and that DSMF’s activities flout two ongoing moratoria that should prevent deep-sea mining in PNG’s territorial waters. On the other hand, a national official has said the company operated within its rights to explore the deep sea for minerals.
- The operation appears to have caught many by surprise, including government authorities meant to oversee such activities.
UK aid agency investing $35m in controversial DRC port
British International Investment (BII), the U.K.’s development finance institution and impact investor, recently announced that it will invest up to $35 million in a controversial deepwater port project in the Democratic Republic of Congo (DRC). This project, conservationists have previously warned, could damage Congo’s critical coastal habitats and sea turtle nesting areas. The Banana port […]
How coastal communities are adapting to sea level rise with ‘living shorelines’
Along the U.S. East Coast, communities are adapting to sea level rise with a promising approach called “living shorelines.” These projects bolster shorelines against stronger storms and higher tides with native plantings and natural materials like driftwood and even holiday trees. Maine Geological Survey coastal geologist Peter Slovinsky joins the Mongabay Newscast to describe several […]
Brazil’s ‘Mothers of the Mangroves’ protect an ecological and cultural heritage
- Hundreds of women from traditional communities in the Brazilian Amazon use education and local knowledge to protect the world’s largest continuous belt of preserved mangroves.
- They organize forums, seminars and workshops to teach how to harvest sustainably from the mangrove ecosystem, such as fishing for specific species within certain periods to preserve the population.
- With the support of nonprofit organizations, they also engage in financial and entrepreneurial education to boost their income and get access to fair-trade markets, contributing to stronger environmental protection and sustainable development.
- Mangroves are vital ecosystems made up of salt-tolerant trees that prevent coastal erosion, store carbon, and support thousands of wildlife species and hundreds of communities; in the Amazon, they’re threatened by expanding monocultures and proposed oil exploration.
Sri Lanka’s blue carbon ecosystems at risk as government seeks way out of economic crisis
- Vidattaltivu Nature Reserve in northern Sri Lanka is an important coastal ecosystem that contains all the main blue carbon habitats, from mangroves to seagrass meadows to salt marshes and tidal flats.
- Despite this, the government recently ordered the removal of protection for a section of the reserve, which observers say is meant to free up land for the development of shrimp farms and similar economic activity.
- Local environmentalists have challenged this move in court, winning a temporary halt to its implementation as they make the case that any short-term economic gain would be dwarfed by the losses arising from destruction of the ecosystem and the attendant carbon emissions.
- While Sri Lanka has gained an international reputation for championing the protection of marine and coastal ecosystems, observers say they fear the country’s ongoing economic crisis may compel the government to release more protected areas for economic activity at the expense of nature.
In the Sundarbans, women are embracing mangrove restoration as an alternative livelihood
- The vast Sundarbans mangrove forests along the southern coast of Bangladesh act as a shield and protect the coastal people and their livelihoods from tropical cyclones and tidal surges.
- In the last couple of years, the number of mangroves in the zone has increased as the government and some NGOs have introduced programs to plant mangrove trees on the coastal embankments as protection measures.
- Women from coastal villages, who know the ecosystem well, have been at the forefront of these reforestation projects and have also become entrepreneurial with mangrove forest resources.
- The involvement of local women and cooperative societies in mangrove restoration and conservation prompts a sense of ownership and agency among mangrove-dependent communities.
50 years of data show that Madagascar’s mangroves are making a comeback
- A new analysis of satellite imagery dating as far back as 1972 reveals that mangroves in Madagascar are rebounding after decades of deforestation.
- The island’s total mangrove cover is down 8% compared with 1972, but a closer look at the data shows that the rate of loss has been declining and even reversed in the last decade.
- Between 2009 and 2019, Madagascar’s mangrove cover increased by 5%, with mangrove forests expanding even more in protected areas — showing that conservation efforts are working.
- Researchers say that mangroves still face many threats from climate change, deforestation and mining, and that continued engagement with coastal communities is critical to empower those communities to protect the local mangroves that they depend on.
On Canada’s West Coast, clam gardening builds resilience among Indigenous youth
- The Nuu-chah-nulth Youth Warrior Family, also known as the Warrior Program, fosters leadership skills in boys and young men across several Indigenous Nuu-chah-nulth nations on the west coast of Vancouver Island in British Columbia, Canada.
- This youth-led program involves taking younger community members into ancestral lands for a variety of traditional activities, among them building and reviving clam gardens, an ancient maricultural method.
- Clam gardens consist of terraced rock walls built across small coastal bays that allow tidal sediment to accumulate and transform rocky or steep shores into flat, productive areas for clams. Clam garden construction and care, along with other cultural practices, such as hunting, spearfishing and medicinal-plant foraging, serve as rites of passage, helping Warrior Program youth reconnect with their heritage.
- This report’s companion video won 2nd place for Best Coverage of Indigenous Communities as part of the 2025 Indigenous Media Awards.
Raw materials become high-value bioeconomy goods at an Amazon science park
- Ahead of hosting 2025’s COP30 climate summit, Belém is betting on the development of products such as honey-based spirits, digital glasses from local wood and jambu-infused medicine at a local tech park.
- The Guamá Science and Technology Park (PCT), operating since 2010 and the first of its kind in the Brazilian Amazon Rainforest, uses technology to transform forest-based resources into high-value products.
- It’s a step toward building a sustainable and thriving billion-dollar bioeconomy that provides local populations with alternatives to deforestation and increases the appeal of sustainably harvesting the region’s resources.
- Future plans include expanding the park for further innovation and to build more science and technology parks in the Amazon as well as fostering networks with other Pan Amazonian countries with similar hubs such as Colombia, Ecuador, and Peru.
Cambodia’s largest mangrove forest is ‘teeming with life,’ biodiversity survey finds
- A survey of biodiversity in Cambodia’s Pream Krasop Wildlife Sanctuary and Koh Kapik Ramsar site identified more than 700 unique species.
- The study also highlights how biodiversity is being lost due to threats including habitat loss and hunting; while this survey recorded rare species including otters and pangolin, a decade ago there would have been tigers and dugongs in the area.
- The researchers plan to conduct further surveys, focusing on the marine environment of the mangrove zone.
A tribe once declared ‘extinct’ helps reintroduce salmon to the Columbia River
- For thousands of years, Kettle Falls was a vital salmon fishing ground for the Sinixt, but early 20th-century dam construction blocked salmon migration.
- Wrongfully declared extinct in Canada in 1956, the Sinixt fought for recognition and were officially acknowledged as Aboriginal Peoples of Canada in 2021.
- In 2023, the U.S. government signed a $200 million agreement with a coalition of tribes, including the Sinixt, to fund an Indigenous-led salmon reintroduction program into the Columbia River system above dams in Washington.
- Sinixt leaders say this project is an important effort to help right a historical wrong in the legacy that led to their “extinction” status, while many hope to one day join salmon efforts on their traditional territory in Canada.

In choice of mangroves or livelihood, Vietnam shrimp farmers choose the latter
- Conservationists and policymakers have long sought ways to alleviate pressure on mangroves from shrimp farming, one of the leading drivers of tropical coastal deforestation.
- A new study shows that despite government-led initiatives seeking to strike a balance between mangrove preservation and shrimp cultivation, farmers in Vietnam’s Mekong Delta are struggling to protect coastal forests with which they compete for farm space.
- The researchers found that despite participating in sustainable shrimp-farming schemes, more than half of interviewed farmers have flouted regulations that require them to maintain 60% mangrove cover.
- Experts say the findings indicate the current mangrove protection model isn’t working in Cà Mau and call on authorities to find another approach that diversifies the incentives and options for farmers to protect local mangroves.
Protecting Nigeria one child & one tree at a time: Interview with Doyinsola Ogunye
- Nigeria’s Doyinsola Ogunye is known across Africa for her work to help children and women build more sustainable futures; the environmental advocate founded the Mental and Environmental Development Initiative for Children (MEDIC) as well as the Recycling Scheme for Women and Youth Empowerment (RESWAYE).
- She says partnerships with corporations and the ability to scale are important in helping the initiatives grow.
- Many of her initiatives center on activities with children and schools — from cleaning up beaches to planting trees — and now, many of the children she initially worked with have entered university and they have carried their experiences into adult life.

Shaping the next generation of Indigenous rangers: Interview with Manni Edwards
- Aboriginal elders in the far north of Australia’s Queensland state are preparing the next generation of junior rangers to conserve endangered southern cassowaries, take care of their traditional land, safeguard their culture, and hold on to millennia of acquired knowledge.
- Along with declining southern cassowary numbers, traditional knowledge and values are diminishing in youth who put more attention on Western knowledge and technology.
- The young rangers not only spend time learning in classrooms; they also go out into the traditional country with elders who help shape their character and identity as caretakers of their people, land, Mother Earth and themselves.
- Ranger Manni Edwards says the way to effective conservation in his community, and in Australia, is by bringing together scientific and traditional ecological knowledge, which includes wisdom and values that forge a connection between people and nature.
Sundarbans fisherfolk are battered by cyclones amid fishing bans
- Fishers in the Bangladesh Sundarbans have been struggling with income due to damage caused to the mangroves by the recent tropical cyclone Remal and also the seasonal ban on resource hunting from June to August.
- In every disaster, poor fisherfolk are entangled more in a complex debt trap for moving on, and this year, the situation is more aggravating as the cyclone hit just before the fishing ban started.
- Nonetheless, the government is adamant on continuing the ban for the sake of forest resource conservation.
- At the same time, the government is still in the planning stage of providing people food support during the ban period, as has been provided to sea-bound fishers during the hilsa harvest ban period.
Shrimp farms threaten Mexico’s mangroves and the jaguars that inhabit them
- Western Mexico’s rapidly expanding shrimp farms, many of which are illegal, are contributing to the deforestation of the Pacific coast’s mangroves, an important habitat for jaguars.
- Satellite images show the total surface area of shrimp ponds along Mexico’s Gulf of California increased by more than 1,100% between 1993 and 2021, to more than 114,000 hectares (282,000 acres).
- Researchers emphasize the importance of small private reserves, like La Papalota in the state of Nayarit, for jaguar conservation: These areas serve as critical sanctuaries and corridors between larger conservation sites, such as Marismas Nacionales Biosphere Reserve, home to a fifth of Mexico’s mangroves.
- Conservationists say urgent action is required to safeguard the remaining mangroves and jaguars, yet efforts continue to be hindered by inadequate enforcement of protection laws and the alleged involvement of cartels reportedly using shrimp farms for money laundering.
‘It is indeed our problem’: Interview with Mário Soares on Brazil’s mangroves
- Mário Soares, a professor of biological oceanography at Rio de Janeiro State University who leads the Mangrove Studies Center (NEMA), has spent more than 30 years studying Brazil’s mangroves, their role in climate change, the effects of oil spills and the importance of mangrove conservation.
- While mangroves fetch a lot of attention in conversations about carbon sequestration, Soares argues that they serve numerous purposes in mitigating climate change; they are also vulnerable to the effects of climate change and must be conserved so that they, in turn, can reduce the vulnerability of the coastal zone.
- Soares also says the carbon market doesn’t solve the problem, only the symptom, because it applies “the market logic,” which created the problem in the first place; meanwhile, we’re not reducing emissions.
- Soares recently spoke to Mongabay about the history and future of Brazil’s mangroves in a video interview.
Indonesia must integrate marine protection with fisheries subsidies, study says
- Indonesia must integrate marine protection measures into its subsidies for small-scale fishers, according to a new study.
- Despite claiming exemption from the 2022 WTO agreement to halt harmful fisheries subsidies, Indonesia needs a strategy to support small-scale fisheries and ensure marine sustainability.
- The government provides various supports, including insurance and fuel subsidies, and has made efforts to protect marine resources and boost fish stocks.
- The study suggests these subsidies should continue, as they are crucial for small-scale fishers’ livelihoods, while also enforcing marine conservation measures.

Bali’s rapid coastal erosion threatens island’s ecosystems & communities: Study
- A recent study revealed that Bali’s coastline shrank from 668.64 kilometers (415.47 miles) to 662.59 km (411.71 mi) between 2016 and 2021 due to human activities and wave circulation, at an average rate of -1.21 meters (3.97 feet) annually.
- The erosion, combined with rising sea levels, threatens the island’s ecosystems, infrastructure and communities, which are economically and culturally significant.
- Despite the erosion, there was a net land increase of 1.25 km2 (0.48 mi2) due to land reclamation and infrastructure development, though these efforts also posed environmental risks.
- The study highlights the need for integrated coastal management to balance environmental protection with the needs of coastal communities.
Peru puts endemic fog oasis under protection
- The Peruvian government has formally granted conservation status to the 6,449-hectare (16,000-acre) desert oasis site Lomas y Tillandsiales de Amara y Ullujalla on the coast of Peru.
- Lomas are unique ecosystems relying on marine fog that host rare and endemic plants and animal species. But they have become threatened by driving, land trafficking, urban development and mining.
- The site, the first of its kind to become protected after more than 15 years of scientific and advocacy efforts, will help scientists understand climatic and marine cycles in the area.
Caught in the net: Unchecked shrimp farming transforms India’s Sundarbans
- The Sundarbans region of India has experienced a significant shift from traditional agriculture to shrimp aquaculture due to erratic weather and increasing global demand for shrimp.
- This surge in shrimp farming has disrupted local communities, displacing them from their traditional livelihoods.
- The rapid expansion of shrimp farming in the Sundarbans is often conducted without proper scientific knowledge or technical training. Scientists warn that this will have long-term consequences.
Beekeeping helps villagers tend coastal forests in Thai mangrove hotspot
- Community-led approaches to mangrove restoration are increasingly recognized as more effective than many state- or market-driven initiatives in terms of both ecological and economic outcomes.
- Nestled within southern Thailand’s mangrove-rich but fast-developing Phang Nga Bay, the village of Ban Nai Nang has developed a mangrove conservation model based on beekeeping.
- By rearing colonies of native honey bees and stingless bees that are important pollinators of local mangrove trees, the villagers earn money from honey sales, which in turn fund their community mangrove conservation efforts.
- Since they began their beekeeping and conservation activities, they’ve observed signs of rejuvenation in their local mangrove forests and are now helping neighboring villages to follow their conservation model through training and mentorship.
Beekeeping for Mangrove Conservation in Thailand
PHANG NGA, Thailand – Community-led mangrove restoration is proving to be more effective than traditional state or market-driven methods, both ecologically and economically. In southern Thailand’s Phang Nga Bay—a region known for its rich mangrove ecosystems but rapid development—the village of Ban Nai Nang has pioneered a unique mangrove conservation approach centered on beekeeping.

Better accounting of peat and mangrove carbon to help Indonesia’s climate policies
- A new study shows how Indonesia can improve its carbon accounting for its vast wetland ecosystems of peatlands and mangrove forests.
- The country is home to 14% of the world’s tropical peatlands and 22% of its mangroves, but the deforestation, burning and conversion of these ecosystems is a major contributor to the country’s overall emissions.
- Researchers have identified gaps in the country’s current greenhouse gas accounting system that, if closed, could yield more accurate and transparent data to inform climate policies and emissions reduction goals.
- Indonesia has set itself a 2030 deadline to turn its forests into a net carbon sink and slash emissions by up to 43% as part of its commitment to the 2015 Paris climate deal.
Efforts to save Cambodia’s coast tread water as fish stocks plummet
- Along the coast of Cambodia, illegal fishing is driving fish stocks toward collapse and fishing communities into poverty.
- The Cambodian government’s capacity for and will to counter fisheries problems are minimal, and several government fisheries reform efforts are off track or behind schedule.
- As one multimillion-dollar foreign project to bolster government capacity and revive Cambodian fish stocks comes to an end, another is just kicking off.
- Whether these efforts to salvage Cambodia’s coastal resources will pay off depends on a range of factors and actors, but so far the plans implemented haven’t been enough to stave off the impending collapse of marine fish stocks.
