Next-gen geothermal offers circular promise, but needs care and caution (Dec 18 2024)
- Enhanced geothermal systems (EGS) and other next-generation geothermal tech show promise as a relatively clean, reliable renewable energy source for a post-fossil fuels future.
- Next-gen geothermal uses a variety of engineering techniques, including hydraulic fracturing borrowed from the oil and gas drilling industry, to create conditions for successful subsurface energy production beyond traditional locations, such as hot springs.
- Enhanced geothermal’s promise of a reliable source of power is huge around the globe, but so far has barely been tapped, say experts. Companies are starting to develop commercial-scale projects, aiming to harness this potential.
- But next-gen geothermal is not without risk. There are concerns, for example, that this tech can induce seismicity. In the past decade, earthquakes shut down two EGS projects in South Korea and Switzerland. Yet, experts say this concern and other environmental impacts, such as pollution, can be controlled and mitigated.
In 2024, Nepal faced old & new challenges after tripling its tiger population (Dec 18 2024)
- Nepal successfully increased its wild tiger population, tripling numbers since 2010, but this achievement brings challenges like human-wildlife conflict, habitat loss and balancing conservation with development.
- Growing tiger populations in areas with dense human settlements have intensified conflicts, creating hardships for communities living near protected areas and raising concerns about fair compensation for losses.
- Expanding infrastructure, such as highways through tiger habitats, poses risks like habitat fragmentation and increased wildlife-vehicle collisions, with budget constraints limiting necessary safeguards.
- Local communities relying on forest resources, especially wild edibles, face dangers from tiger encounters, highlighting the need for safer practices and improved community management.
Renewables won’t save us from climate catastrophe, experts warn; what will? (Dec 17 2024)
- Demand for renewable energy, particularly solar panels, is growing at an exponential rate. But the shift to solar, wind, EVs and other sustainable tech solutions has sparked an environmentally destructive mining boom and is itself carbon intensive.
- And even as renewables boom, we’re burning more fossil fuels than ever, setting another record for emissions in 2023. So it appears high tech alone can’t save the world from catastrophic climate change; only massive cuts in fossil fuels can do that, say experts. But even addressing the climate change planetary boundary isn’t enough.
- Five other planetary boundaries are in the danger zone, though solutions exist to reverse these negative environmental trends, say analysts. But for those solutions to happen, governments must shift trillions of dollars in “perverse subsidies” (that support fossil fuels and do environmental harm) to renewable energy.
- Without real, drastic, decisive action now, the sixth great mass extinction could be unstoppable and doom modern life as we know it. Still, there’s another way forward: Learn from Indigenous cultures, with their willingness and ability to integrate into the biosphere, and to humbly turn away from greed and overconsumption.
Top Mongabay podcast picks for 2024 (Dec 17 2024)
- With more than 40 episodes published, 2024 was another busy year for Mongabay’s podcast team, featuring many fresh interviews, a new season of the Mongabay Explores series, an award, and its first year featuring a two-person co-host team at the microphone.
- Here are a few of the team’s favorites worth listening to–and revisiting–as we move into 2025.
Communities launch new Thawthi Taw-Oo Indigenous Park amid Myanmar civil war (Dec 17 2024)
- On Dec. 10, communities in Myanmar’s Kayin state launched the Thawthi Taw-Oo Indigenous Park amid the country’s ongoing civil war. Some representatives call it a ‘peaceful resistance’ to the Myanmar state military.
- Inspired by the Salween Peace Park to its south, the new park is roughly the same size, spread across 318 villages, and includes 28 kaws (ancestral customary lands), four community forests, seven watersheds, six reserved forests and one wildlife sanctuary.
- The park’s charter is based on customary laws and includes guidelines to conserve the area like protected forests, rotational farming, and areas restricted for killing culturally important wildlife species.
- Communities, the Karen Environmental and Social Action Network (KESAN) and representatives from the Karen National Union (KNU) are working in coordination to govern and manage the park, including measures to strengthen peoples’ self-determination.
Shipbreaking pollutes Türkiye’s coast despite European cleanup efforts (Dec 17 2024)
- 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 97 deadly accidents between 2013 and 2022.
- 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.
Hundreds of whales to be harpooned as Iceland issues new hunting licenses (Dec 17 2024)
- On Dec. 6, Iceland’s interim government announced it had issued five-year commercial whaling permits to hunt fin and minke whales.
- The permits, issued to domestic whaling companies Hvalur hf and Tjaldtangi, allow the hunting of 209 fin whales and 217 minke whales each year in Icelandic waters.
- The move follows recent government decisions to briefly pause whaling based on welfare concerns about using grenade-tipped harpoons for hunting, and then resume it again.
- Conservationists say the new whaling decision is a blow to marine conservation and question its timing by an interim government that’s soon due to hand over power to a coalition that isn’t pro-whaling.
‘Like you, I fear the demise of the elephants’ (Dec 17 2024)
- There are nearly 9,000 inland protected areas across the African continent, covering 4.37 million square kilometers (1.69 million square miles).
- These protected areas are at the center of conservation policymaking by African countries hoping to safeguard nature and threatened wildlife.
- Under the UN Global Biodiversity Framework’s “30×30” target, the amount of conserved land in Africa would significantly expand.
- As part of a reporting series on this goal, Mongabay visited protected areas in three countries: Uganda, Rwanda and Kenya.
Indonesia reforestation plan a smoke screen for agriculture project, critics say (Dec 17 2024)
- Critics say an Indonesian government plan to reforest 12.7 million hectares (31.4 million acres) of degraded land is a smoke screen to offset deforestation from a massive agricultural project.
- The food estate program includes a plan to establish 2 million hectares (4.9 million acres) of sugarcane plantations in Papua.
- A new study by the Center of Economic and Law Studies estimates the food estate program would emit 782.5 million tons of carbon dioxide, nearly doubling Indonesia’s global carbon emission contribution.
- Indonesia climate envoy Hashim Djojohadikusumo, who is also the brother of President Prabowo Subianto, says the food estate program is necessary for food security and that forest loss will be offset by reforestation; critics, however, say reforestation cannot compensate for the destruction of natural forests.
Scientists, Māori experts uncover new insights into rare spade-toothed whale (Dec 17 2024)
- Spade-toothed whales (Mesoplodon traversii) are among the rarest and least-studied whales, partly due to their deep-diving behavior and long periods spent underwater in the vast, underexplored South Pacific Ocean.
- Until recently, only six records of spade-toothed whales had been documented over 150 years, all but one found in Aotearoa New Zealand, a known hotspot for whale strandings.
- The seventh and most recent record, a 5-meter (16-foot) male, stranded in New Zealand in July 2024, was recently dissected by scientists and Māori cultural experts at a scientific research center.
- A key finding was the presence of tiny vestigial teeth in the upper jaw, offering insights into the species’ evolutionary history, with further discoveries anticipated as analysis continues.
On Indonesia’s unique Enggano Island, palm oil takes root in an Indigenous society (Dec 17 2024)
- Formed millions of years ago in the Indian Ocean by a process independent of tectonic collision, Indonesia’s Enggano Island is now home to many unique species and a diverse Indigenous society of subsistence farmers.
- Since the early 1990s, developers have sought to obtain control over large parts of the island, but encountered staunch opposition from its six Indigenous tribes.
- Today, PT Sumber Enggano Tabarak, which has been linked to the billionaire-owned London Sumatra group, is seeking to establish an oil palm plantation over 15,000 hectares (37,000 acres).
- Civil society researchers and Indigenous elders say the island lacks sufficient freshwater to provide irrigation to both the community and an industrial oil palm plantation, and that a plantation at scale risks catalyzing an ecological crisis.
We must prioritize rangeland conservation for planetary health and biodiversity (commentary) (Dec 16 2024)
- Rangelands, despite their size and significance, have been historically under-appreciated in global conservation and climate discussions, a new op-ed argues.
- They cover more than 79 million square kilometers of grasslands, savannas, deserts, shrublands, and tundra globally. But they are more than just expansive open landscapes – rangelands are central to global economies, ecosystems, and cultures.
- Ahead of the International Year of Rangelands and Pastoralists in 2026, governments and conservationists have an opportunity to lay groundwork to ensure their health for wildlife habitat and their use by pastoralists is sustainable.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
‘Shifting baselines’ in Cabo Verde after 50 years of declining fish stocks (Dec 16 2024)
- In Cabo Verde, as in many low-income countries in Africa, the historical record of fish catch is incomplete, making it hard to know what’s been lost and what’s required to fully rebuild.
- In a new study, researchers interviewed fish workers to understand how catches have changed over the last five decades, finding evidence of a major decline in volume of catch and maximum size of key species.
- The study also shows that young fishers and fishmongers don’t fully realize the scale of the loss — a case of what scientists call “shifting baselines.”
- Fishing communities on the West African mainland tell a similar story of decline, pointing to the urgency of centering local knowledge when devising fisheries management and conservation policies.
Armed conflict, not Batwa people, at heart of Grauer’s gorillas’ decline in DRC park (Dec 16 2024)
- The decline in critically endangered Grauer’s gorillas between 1994 and 2003 in the highland sector of Kahuzi-Biega National Park in the Democratic Republic of Congo was due to the impacts of armed conflict, rather than the presence or absence of Indigenous communities, according to a new study.
- The finding, including recent analysis of forest loss in parts of the park where Indigenous Batwa people returned, challenges simple but competing narratives that the region’s Batwa people are either forest destroyers or forest guardians, say various primatologists.
- After the onset of the Rwandan genocide and Congo Wars, which drove an influx of refugees, poaching, hunting and mining in the region, estimates of Grauer’s gorillas dropped from about 258 to 130 individuals, only to rise again once the Second Congo War ended.
- Researchers and conservation authorities say conservation in Kahuzi-Biega National Park remains challenging, but that Indigenous people should be included in environmental stewardship.
Grassroots efforts sprout up to protect Central America’s Trifinio watershed (Dec 16 2024)
- A major watershed in Guatemala, Honduras and El Salvador has been so polluted, industrialized and interfered with that 20% of it could dry up in the next few decades, according to a U.N. report.
- The Trifinio Fraternidad Transboundary Biosphere Reserve, which covers the triborder region of Guatemala, Honduras and El Salvador, suffers from a free-for-all of deforestation, chemical runoff and mining that threatens the existence of the watershed.
- If it dries up, millions of people could be left without water for drinking, bathing and farming.
- While conservation groups continue to lobby for funding, residents frustrated with government inaction have started to organize themselves to fight everything from mining and runoff to illegal building development.
Young people in Africa call for a fair increase in funding for climate adaptation (Dec 16 2024)
- Young activists in Africa are calling for doubling adaptation financing for climate change.
- The youths presented their demands during COP29, dubbing it the ‘six30 campaign’.
- Experts say the adaptation funds for the continent is seriously underfunded.
Brazil paper and pulp industry invests in blockchain to comply with EUDR (Dec 16 2024)
- Brazil’s paper and pulp industry says the European Union’s deforestation-free products regulation (EUDR), which will come into effect in late 2025, won’t affect the sector’s operations, which has already traced its supply chains “from farm to factory” for more than two decades and doesn’t source from illegal deforested areas.
- The EUDR will require suppliers to prove that their products exported to the EU aren’t sourced from illegally deforested areas; in Brazil, experts say it will help halt illegal deforestation in the Amazon.
- To fulfill some specific EUDR requirements, companies need to invest in blockchain and other technologies, which could increase the cost per ton of pulp by up to $230, according to the Brazilian Tree Industry (Ibá).
- The EUDR postponement was received differently by the industry and experts: While Ibá says it would allow “a smoother and more effective implementation,” given some aspects that need improvement from the EU Commission, deforestation experts say there is no time to wait, as deforestation continues and the climate crisis gets worse.
High-flying concessions: Clandestine airstrips, coca crops invade Ucayali’s forests (Dec 16 2024)
- An investigation by Mongabay Latam and Earth Genome identified 45 clandestine airstrips in the rainforest in Peru’s Ucayali department.
- Ten of these airstrips, most likely built for narcotrafficking activity, are located inside nine forest logging concessions.
- Peru’s forest and wildlife monitoring agency, OSINFOR, says only four of these logging concessions are still active.
- Complaints made by concession holders to environmental authorities about the airstrips, as well as associated deforestation and coca cultivation, have been shelved.
Greater Mekong serves up 234 new species in a year, from fanged hedgehog to diva viper (Dec 16 2024)
- Researchers and local nature enthusiasts described 234 new-to-science species across the Greater Mekong region in 2023.
- Among the new assortment of critters are sweet-smelling plants, glamorous snakes, a dragon lizard, a psychedelic-orange crocodile newt, and several new mammals, including a mole shrew and a fanged hedgehog.
- The Greater Mekong is a fast-developing region of Southeast Asia, characterized by intensive agriculture, internationally significant inland fisheries and rapid urban expansion.
- As such, the newly described species and their habitats are under pressure from multiple threats, not least from the illegal wildlife trade that also flourishes in the region. Experts say consistent and concerted action is required to secure their future.
Illegal timber from Amazon carbon credit projects reached Europe, U.S. (Dec 16 2024)
- Amazon timber from carbon credit projects targeted by the Brazilian Federal Police was sold to companies in Europe and the United States.
- The group is suspected of land-grabbing and laundering timber from Indigenous territories and protected areas.
- Most of the exported timber belongs to the almost-extinct ipê species and was sent to a company in Portugal.
- The group is also suspected of using fake documents to launder cattle raised in illegally deforested areas.
Endangered seabirds return to Pacific island after century-long absence (Dec 14 2024)
- Endangered Polynesian storm petrels have returned to Kamaka Island in French Polynesia for the first time in more than 100 years, after conservationists used drones to remove the invasive rats eating the birds’ eggs and chicks.
- Scientists attracted the birds back to the island using solar-powered speakers playing bird calls recorded from a neighboring island, with monitoring cameras showing regular visits, though nesting has not yet been confirmed.
- The project demonstrates successful collaboration between international conservation groups and local communities, with the local Mangareva community’s knowledge and support proving crucial to the operation’s success.
- The birds’ return could benefit the entire island ecosystem, as seabirds bring nutrients from the ocean that help sustain both terrestrial and marine life around the island.
Study looks for success factors in African projects that heal land and help people (Dec 13 2024)
- Land degradation across Africa impacts the lives of rural Africans, who depend heavily on natural resources.
- Reversing land degradation while improving livelihoods can be tricky, and not all initiatives succeed.
- A recent Sustainability Science study examined 17 initiatives in 13 African nations to tease out what factors contribute to success or failure.
- The study finds that tapping into social relationships, providing adequate incentives to overcome risk-adverse behaviors, and maintaining momentum over the long term emerged as key factors in an initiative’s success.
Illegal cockfighting threatens endangered sea turtles across Central America (Dec 13 2024)
- The hawksbill sea turtle (Eretmochelys imbricata), a critically endangered species, has long been exploited for its shell, used in a wide range of ornaments, including, in Costa Rica, the deadly spurs used in illegal cockfighting.
- Cockfighting is banned in Costa Rica, but the tradition persists underground, with authorities increasing their efforts to seize hawksbill spurs.
- Conservationists are also helping to train inspection officers to identify hawksbill products brought into Costa Rica from neighboring countries.
- When poachers harvest hawksbills, they’re not targeting them specifically for spurs but also for other products, which often find their way into tourist shops and online markets worldwide.
Direct air capture climate solution faces harsh criticism, steep challenges (Dec 13 2024)
- Direct air capture — geoengineering technology that draws carbon dioxide from the air, allowing it to be stored in geologic formations or used by industry — is being heavily hyped as a climate solution.
- But as direct air capture (DAC) pilot projects an startups grow in number around the world, fueled by investment and government funding in the U.S. and elsewhere, this proposed climate solution is becoming ever more divisive.
- Critics paint DAC as a costly, ineffective distraction from drastically slashing fossil fuel extraction and emissions. The use of captured carbon by the fossil fuel industry to squeeze ever more oil from wells comes in for particularly sharp criticism.
- Though carbon dioxide removal (CDR) may be needed to help limit the worst impacts of global warming, experts say betting on direct air capture is riddled with challenges of cost and scale. Two hurdles: sourcing sufficient renewables to power DAC facilities, and minimizing carbon-intensive DAC infrastructure.
Recycling gold can tackle illegal mining in the Amazon, but is no silver bullet (Dec 13 2024)
- Artisanal and small-scale gold mining in Brazil’s Tapajós River Basin emits 16 metric tons of CO2 per kilo of gold produced, and 2.5 metric tons of mercury annually, a study has found.
- Researchers suggest that recycling gold could dramatically reduce harmful emissions, along with other solutions such as formalizing mining, adopting clean technologies, and improving gold supply chain transparency.
- Economic dependence, mercury accessibility, and a demand for gold sustain small-scale gold mining, while enforcement risks pushing miners into ecologically sensitive areas.
- In November, Brazil launched a federal operation in the Tapajós Basin to expel illegal gold miners from the Munduruku Indigenous Territory, imposing millions of reais in fines to curb the damage caused by gold mining.
