Nepal announces its snow leopard population after first-of-its-kind assessment
- Nepal has released its first consolidated national estimate of snow leopards, placing the population at 397 individuals, after synthesizing multiple studies conducted between 2015 and 2024.
- Despite covering just 2% of global snow leopard habitat, Nepal hosts nearly 10% of the global population, making it the fourth largest population of the species.
- The estimate contributes to the Population Assessment of the World’s Snow Leopards (PAWS), a global initiative aiming for standardized and robust population assessments across all 12 snow leopard range countries.
- While the estimate is a milestone, it’s based on just 43% of Nepal’s potential snow leopard habitat, with key areas like Dhorpatan and Api-Nampa still under-surveyed.

Rare polar bear cub footage offers crucial conservation insights
- Scientists have captured rare footage of female polar bears and their newborn cubs emerging from maternal dens in the Arctic.
- Using remote cameras and satellite collars, researchers were able to track down polar bear dens in Norway’s Svalbard region and get insights into their behavior.
- On analyzing the data, researchers found that the bears typically stayed in and around the dens for 12 days after first emerging from them; they were also found to abandon the dens earlier than previously thought.
- Polar bear denning and the subsequent den emergence is a crucial period during which cubs transition from the warm environment of the dens to the harsh environment outside; the amount of time cubs spend in the dens is believed to have implications for their survival.

The year in tropical rainforests: 2024
- The year 2024 saw significant developments in tropical rainforest conservation, deforestation, and degradation. While progress in some regions provided glimmers of hope, systemic challenges and emerging threats highlighted the fragility of these ecosystems.
- Although a complete comparison of tropical forest loss in 2024 with previous years is not yet available, there are currently no indications that this year’s loss will be markedly higher. A sharp decline in deforestation in the Brazilian Amazon—partially offset by widespread forest fires—suggests the overall rate of loss may be lower.
- This analysis explores key storylines, examining the political, environmental, and economic dynamics shaping tropical rainforests in 2024.
Next-gen geothermal offers circular promise, but needs care and caution
- 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.

- The five-year XPRIZE Rainforest competition was launched in 2019 to identify solutions to automate rainforest monitoring.
Shipping emissions reduction sheds light on marine cloud geoengineering
- Unprecedented marine heat waves in the North Atlantic have been driven in part by a recent drop in shipping emissions, leading to a reduction in highly reflective marine clouds that had previously masked some of the warming from humanity’s greenhouse gas emissions, studies find.
- New limits on sulfur dioxide emissions from shipping, introduced by the International Maritime Organization in 2020, created an inadvertent “natural experiment” that is helping to improve models of the interaction between atmospheric aerosols, clouds and climate.
- The sulfur dioxide emissions reduction also provides the clearest test to date of marine cloud brightening (MCB) — a controversial geoengineering approach proposed to mitigate climate change. It shows that to be effective and avoid a dangerous termination shock, MCB would need to be continuous and sustained.
- Reducing atmospheric aerosol pollution has major benefits for human health, but will also inevitably lead to an unmasking of more dangerous climate warming. This means that improvements in air quality must simultaneously be coupled with decarbonization, experts say.

Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.

50 years of geographic insight: In interview with Jack Dangermond on Esri’s journey and the future of GIS
- The digital mapping platforms developed by Esri, including ArcGIS, have revolutionized conservation and environmental planning, management and policymaking. Esri co-founder Jack Dangermond calls geographic information systems (GIS) “a sort of intelligent nervous system for our planet at a time when humanity desperately needs one to address the environmental and humanitarian crises at hand.”
- He credits Esri’s success to a sustainable trajectory of heavy investment in R&D, not being beholden to outside investors, and providing discounted and free use of its software to environmental nonprofits.
- In this interview with Mongabay founder and CEO Rhett A. Butler, Dangermond says that technology, amid the current fractured political climate, should be employed to encourage understanding rather than dwell on divisions.
- The text of the interview has been edited for clarity and flow.
New study upends common belief that birds escape winter to save energy
- Scientists have found Eurasian blackbirds migrating to warmer regions in winter didn’t save more energy compared to members of the same species that stayed behind.
- A recently published study used surgically implanted biologgers to measure the birds’ heart rate and body temperature over the course of the winter.
- The study also found that migrating birds started saving energy for migration by lowering their heart rate and body temperature almost a month before their departure.
- The research raises important questions on why birds migrate if there’s no energy benefit, and where the unaccounted energy is being used instead.

Scientists find unexpected biodiversity in an African river, thanks to eDNA
- Scientists have used environmental DNA analysis to identify 125 species of aquatic and terrestrial animals in the remote Corubal River in West Africa.
- The identified species include critically endangered animals as well as species that weren’t previously known to occur in the region.
- The Corubal flows through Guinea and Guinea-Bissau; because of its remote nature, there haven’t been a lot of large-scale attempts to study the biodiversity in the river and its basin.
- The scientists are also working to collect specimens and tissue samples from animals encountered along the river to build a DNA reference database for the future.
At the ‘Biodiversity Olympics,’ scientists work to democratize rainforest tech
- Over the course of three weeks in July, six teams showcased technology that could potentially automate biodiversity monitoring in rainforests.
- The event in Manaus, Brazil, was the final round of testing for a $10 million competition organized by the nonprofit XPRIZE Foundation.

- In addition to gauging how the teams presented scalable and affordable solutions, the competition also judged them on how they collaborated with Indigenous communities in Brazil.
Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.
Arctic melt ponds influence sea ice extent each summer — but how much?
- July marks the midpoint of the summer sea ice melt season, during which ice declines rapidly under the almost constant Arctic sun, and melt ponds form on ice floes. Scientists study melt ponds to better understand sea ice dynamics and to help forecast the annual sea ice minimum in September.
- Sea ice melt ponds absorb more solar energy than bare ice or snow but far less than open ocean, which complicates the story of summer sea ice melt. But in the past, scientists lacked the tools to accurately measure melt pond impacts.
- New remote sensing data look at sea ice from different satellite resolutions. High-resolution imaging sends a clear picture of melt ponds in a very small area, while low-resolution imaging produces a fuzzy picture of them across the entire Arctic.
- A combination of satellite data and on-the-ice observations now help scientists track the evolution of sea ice melt ponds and their influence on the overall decline of sea ice in the Arctic.
Blockchain as a carbon market fix: Interview with William ten Zijthoff, Flávia De Souza Mendes & Maximilian Rösgen
- Satellite and blockchain technology could be combined to address the lack of transparency and accountability in the carbon market, according to a recently published report.
- The report suggests that while satellite imagery can provide data in real time, blockchain technology could be used to ensure that the data are accessible, transparent and not tampered with.
- The combination of the two technologies, according to the report, could also be used to improve traceability and ensure compliance with deforestation regulations.
- The complicated nature of blockchain technology, the lack of regulatory infrastructure and high energy consumption are likely causing skepticism and relatively slower uptake for its application in environmental monitoring.
Cloud brightening over oceans may stave off climate change, but with risk
- Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.
- However, this solar radiation management (SRM) geoengineering technique is highly controversial, and experts say governance of MCB field experiments and deployment is needed now at the national and international levels.
- Ongoing efforts to include marine cloud brightening under an international anti-marine pollution treaty, the London Protocol, could be one effective route to setting standards for research and field experiments.
- But if MCB is deployed on a large scale, some experts say there is the potential for serious negative effects on the global climate system. These impacts could be especially severe if deployment is uncontrolled and lacks science-based governance.
High-resolution maps reveal surprises about how ice shelves melt
- The first detailed maps from underneath an ice shelf in Antarctica have revealed previously unknown shapes and melting patterns.
- While researchers are yet to fully understand what causes the patterns in ice erosion, they say it indicates new information about how oceans are melting ice.
- The scientists involved in the study deployed an autonomous vehicle that traveled underneath the ice and used multibeam sonars to map the underside of the ice shelf.
- Ice shelves are floating masses of ice attached to land mass; while their melting doesn’t directly contribute to sea level rise, it can destabilize glaciers and cause them to flow faster.
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.
Geoengineering gains momentum, but governance is lacking, critics say
- As the climate crisis advances, geoengineering — intentionally modifying Earth systems on a large scale to cool the planet or store additional carbon — is increasingly a hot topic. But an intense debate is raging as to how to govern research and deployment of these deeply contentious strategies.
- Stratospheric aerosol injection (SAI) — involving the release of sunlight-blocking particles such as sulfur dioxide into the lower atmosphere to block the sun’s rays — is at the forefront of a range of geoengineering technologies and approaches.
- Most SAI research to date involves modeling, while small-scale experimentation is foundering. SAI, though likely capable of cooling Earth’s climate, comes laden with governance challenges, myriad uncertainties and knock-on effects to the climate, ecosystems and human health.
- Projected deployment within a decade or two is cause for concern, say experts who warn that policy guidance and regulatory mechanisms at the national and international levels are now patchy at best, leaving huge gaps in oversight, transparency and monitoring of field research and potential deployment.
The Inventory, a Wiki for wild tech: Interview with Jake Burton & Alex Rood
- A Wikipedia-style tool cataloging conservation technology aims to help scientists and conservationists identify the best technology tools that can be deployed for their work.
- The Inventory was developed by conservation technology community WILDLABS in collaboration with Octophin Digital.
- Apart from serving as a database, users can also leave reviews of tech products used for conservation and wildlife monitoring.
- The Inventory also displays projects that are still in development and could benefit from funding and external expertise.
Are the Amazon’s biggest trees dying? Forest coroners investigate
- As tropical forests are degraded and decline at increasing rates the world over, the fate of these forests’ largest trees remains unknown.
- Big trees store a huge amount of carbon, so assessing their current mortality rates and causes of death (especially due to escalating climate change) is vital to calculating how much tropical forest carbon sinks could decline in the future.
- The Gigante project, getting started in the Brazilian Amazon in June 2024, is initiating an innovative new protocol utilizing detailed drone surveys combined with ground truthing to evaluate tropical big tree mortality.
- The project has begun an identical survey in Panama and will conduct others in Malaysia, Cameroon and at another Amazon location. Knowledge of how tropical big trees are faring could help improve climate model accuracy. A Mongabay reporting team joined the Gigante project in Brazil at the start of this groundbreaking work.
Don’t even study it: Geoengineering research hits societal roadblocks
- As climate change accelerates, some scientists are calling for more field research into solar geoengineering concepts. However, these ideas are running into opposition from other researchers, some governments and the public.
- A series of recent setbacks has put solar geoengineering research on the back foot, attempting to figure out a way to navigate the opposition.
- Proponents of field research say it would help humanity better understand the potential and problems with solar geoengineering, while opponents argue that there are too many risks and it could take our eye off the ball: cutting carbon emissions.
- The debate has spilled into the international arena, pitting nations that support greater research against those that would like to see a solar geoengineering non-use agreement.
As New England forests are razed for solar power, experts urge smarter siting
Every year across a handful of New England states and elsewhere in the U.S., developers cut forests to build utility-scale solar energy projects. Journalist and author Judith Schwartz lives near a forest in the otherwise environmentally progressive state of Vermont, where a company plans to install an 85-acre (34-hectare) solar power project and export the […]
Sun block: The promise and peril of solar geoengineering
- Recent research and interest, especially from the U.S. government, has pushed a solar geoengineering idea known as SAI, or stratospheric aerosol injection, to the top of lists of potential ideas to cool the planet. SAI would use fleets of high-flying aircraft to disperse sunlight-reflecting particles, including sulfates, into the stratosphere.
- As climate change worsens and carbon emissions continue to rise, researchers say we must be ready with other potential tools to stave off total catastrophe, such as the disintegration of the West Antarctic Ice Sheet with sea-level rise that would drown coastal cities.
- But critics say any geoengineering is too unpredictable and could allow governments to lower their ambitions on cutting emissions. They also argue that there’s no global governance policy to implement geoengineering justly.
- As debate intensifies, however, some feel it’s only a matter of time, given the current and projected trajectory of warming, until the world seriously considers geoengineering deployment.
Space mission that maps forests in 3D makes an early comeback
- NASA’s GEDI mission, which maps the Earth’s forests in 3D using lasers, is back in operation from a hiatus, six months earlier than expected.
- Since 2018, GEDI has used spaceborne laser altimeters to help scientists gather data on forest structure, aboveground biomass and carbon stored in forests.
- Following resumption of operations, researchers have used GEDI data along with data from other missions as well as analysis tools to estimate the aboveground carbon stored in protected areas and Indigenous territories in the Amazon Rainforest.
Regions with highest risks to wildlife have fewest camera traps, study finds
- Camera traps are widely used to monitor biodiversity and guide conservation actions, but a first-of-its-kind study finds the technology isn’t as prevalent in highly biodiverse areas that face the most threats from human activities, such as the Congo Basin and the Amazon Rainforest.
- Even in areas with a high number of camera-trap studies, nearly two-thirds were conducted outside the regions facing the highest risk of animal extinctions.
- Country income, accessibility, mammal diversity and biome largely determine the locations of nearly two-thirds of camera-trap research.
- Experts suggest expanding the network of camera-trap studies, building capacity among local research communities, and leveraging tools and platforms that help with data sharing and analysis to address these disparities.
Studying snakes without rattling them? There’s now tech for that
- Scientists have used tiny, noninvasive radio transmitters and accelerometers to study the habitats and behaviors of red diamond rattlesnakes.
- While the radio transmitters help researchers keep track of the snakes, the accelerometers give them an in-depth understanding of the snakes’ physical movements as they hunt, eat and even mate.
- Historically, tracking snakes has involved surgically implanting telemetry radios into them, but this process is time-consuming and also risks infecting the animals.
- Red diamond rattlesnakes, native to southwest California in the U.S. and Baja California in Mexico, face increasing threats from habitat loss and vehicle strikes.
Kenyan farmers turn to WhatsApp & AI tools to combat crop diseases
- Farmers in Kenya and other countries are using online chat groups and artificial intelligence (AI) tools to help combat crop losses due to pests and diseases.
- New research shows chat groups modeled on those used in human health care can offer benefits to farmers and enhance their communication with plant doctors.
- Organizations such as PlantVillage and CABI are using such digital tools and chat groups to expand their reach and augment the services offered through their extension agents and plant clinics; participating farmers say the knowledge they gain through digital tools can ultimately help increase their crop yields.
Reimagining insect research: Interview with Roel van Klink and Leandro Nascimento
- Three out of every four known species on Earth are insects, but efforts to monitor, study and protect them have been lagging worldwide.
- A new themed issue published in the journal Philosophical Transactions of the Royal Society delves into four tech tools that have the ability to reshape insect research in the coming years.
- The issue highlights acoustic monitoring, remote sensing using radars, computer vision, and DNA sequencing as potential tools that could help scientists and researchers ramp up global insect biodiversity monitoring.
Using immersive media to strengthen support for the environment: An interview with Wendy Schmidt
- Wendy Schmidt, co-founder of a constellation of philanthropic initiatives, uses “systems thinking” to address ecological, social, and economic issues. She leverages her background as an interior designer and journalist to focus on sustainability and communications. Through the Schmidt Family Foundation and initiatives like the 11th Hour Project, Schmidt promotes “venture philanthropy,” emphasizing scalable, high-impact solutions to environmental problems using cutting-edge technology and interdisciplinary research.

- Her philanthropic approach prioritizes inclusivity and equity, integrating traditional knowledge and contemporary science to create innovative, respectful solutions for historically marginalized communities and addressing global challenges like climate change and biodiversity loss.
- Schmidt spoke with Mongabay Founder Rhett Ayers Butler in May 2024.
Crowdsourcing eDNA for biodiversity monitoring: Interview with Kristy Deiner
- Scientists at ETH Zurich launched a global project to gather biodiversity data from 500 lakes around the world.
- As part of LeDNA, citizen scientists from around the world collected environmental DNA samples from lakes to commemorate the U.N.’s International Day for Biological Diversity.
- With the samples, the team behind the project aims to understand more about how lakes could potentially serve as “sensors” detecting the richness of life in the catchments surrounding them.
As Big Tech eyes the carbon market, will it work this time?
- Tech giants Meta, Microsoft, Google and Salesforce have announced the launch of an alliance that aims to invest in nature-based carbon removal projects.
- The Symbiosis Coalition has promised to purchase carbon credits worth 20 million metric tons of carbon dioxide by 2030.
- The collaboration comes at a time when the voluntary carbon market has faced increasing scrutiny over allegations of greenwashing, human rights abuses and lack of transparency.
- The coalition says that it will focus initially on afforestation, reforestation and revegetation, and that it has worked with independent experts to establish guidelines to ensure accountability and benefit sharing with local communities.
Collar cameras shed light on quirky baboon diet
- A new study has found that chacma baboons (Papio ursinus) like to feed on antelope poop, especially during drier months when vegetation might be sparse.
- Researchers deployed collar cameras attached to four baboons in South Africa as part of a documentary film in 2017; they later analyzed footage from two of them.
- They also gained insights into how baboons were interacting with other species that share their habitat.
- According to the study, collar cameras gave researchers a “primate-eye perspective” into the animals’ lives, and could be used in the future to gain more insights into other behavioral traits.
In Brazil’s Cerrado, aquifers are losing more water than they can replace
- A new monitoring model combining satellite images with artificial intelligence can identify variations in the volume of Brazilian aquifers.
- The Urucuia, one of the largest aquifers in the Cerrado biome, saw its water volume decrease by 31 cubic kilometers (7.43 cubic miles) over two decades; most of it is in western Bahia, where monoculture plantations are gaining ground.
- According to researchers, Brazil’s groundwaters—which cover 2.84 million square kilometers (1 million square miles) — remain “an unknown resource,” and few tools exist to monitor them.
Green credentials of electric vehicles come under fire
- Electric vehicles are often presented as a key technology for drastically reducing greenhouse gas emissions, thus helping curb climate change.
- But manufacturing electric cars requires the mining of critical minerals for batteries, like lithium and cobalt, that are largely sourced in developing countries. Local traditional and Indigenous communities say the mining is already harming their way of life, is polluting, and damaging biodiversity.
- The rush to embrace EVs, say scientists, runs the risk of trying to find a silver-bullet solution to one planetary boundary crisis (global warming) by violating other equally important existential boundaries, including biosphere integrity, land system change, freshwater use, and novel entity (air and water pollution).
- Analysts say a far better way to tackle the global environmental polycrisis is by reducing overall resource consumption. New technology is not enough, by itself. To make life on the planet truly sustainable, humanity must alter lifestyles, redesigning societies to use less, while preserving quality of life for all.
Report ranks 60+ ideas, including geoengineering, to save the Arctic
- Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
- A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
- The report ranked tried and true measures, like restoring peatlands, the highest, but some geoengineering ideas, such as solar geoengineering, also ranked high.
- Researchers say, however, that while geoengineering ideas may be worth studying, the goal right now must be to aggressively cut emissions. Some also fear that geoengineering will become a costly distraction, diverting attention from the need for fossil fuel companies to cut production, and for decarbonization of the economy.
New satellite data documents deforestation across ecosystems worldwide
- New satellite data documents the loss of vegetation in all types of ecosystems, not just tropical rainforests, around the world.
- The OPERA DIST-ALERT was developed by the makers of popular forest monitoring platform Global Forest Watch.
- The monitoring system incorporates managed forests, grasslands, shrublands and croplands along with tropical forests.
- The data obtained from two of NASA’s Landsat satellites and two of the European Space Agency’s Sentinel-2 satellites reflected lost vegetation around the world due to various factors — ranging from fires in Canada to logging in the Republic of Congo and cyclones in Malawi.
On foot and by drone, radio tracking helps rehabilitate pangolins in Vietnam
- Conservation NGO Save Vietnam’s Wildlife is employing radio tracking to follow rehabilitated pangolins rescued from the illegal wildlife trade, even in difficult terrain and when the animals burrow underground.
- Tracking these pangolins on foot and using a novel radio telemetry drone has not only allowed the organization to assess the survival of released pangolins, but also improved the team’s knowledge of the secretive animals’ behaviors and habitat needs.
- However, this radio-tracking work is vulnerable to funding challenges, as the expectation that conservation work result in published papers can make it difficult to find long-term funding for basic equipment like radio tags.
Scientists explore nature’s promise in combating plastic waste
- Since 1950, humanity has produced more than 8.3 billion metric tons of plastic. Most has ended up in landfills or the environment. Now, scientists are working on biological solutions to address the plastic pollution crisis at every stage of the material’s life cycle.
- Innovative new filters built from naturally occurring ingredients can capture micro- and nanoplastics in all their diverse forms. These filters could remove plastic contamination from drinking water, and prevent microplastic pollution in industrial and domestic wastewater from reaching rivers and oceans.
- Plastic-degrading enzymes, isolated from microbes and insects and engineered for efficiency and performance in industrial conditions, can break plastics down at the molecular level and even be used to turn plastic waste into new useful chemicals.
- Biological solutions are being developed for a range of pollutants, not just plastics. But this technological research is still young. Crucially, we must not allow solutions for existing pollutants to make us complacent about the impact of new chemicals on the environment, or we could risk making the same mistakes again.
AI model maps global tree canopy heights in hi-res, with carbon counting in mind
- Scientists have used high-resolution satellite images to create a map of global canopy heights, and to also develop an AI model that can predict canopy heights.
- Tech company Meta collaborated with nonprofit organization World Resources Institute to develop the open-source map and model.
- While the map aims to establish and serve as a baseline for conservation initiatives, the AI model could be used to predict canopy heights in areas where high-quality data aren’t available.
- Canopy height is an important indicator of forest biomass and aboveground carbon stock, and is used to measure the progress of forest restoration efforts.
Bioacoustics and AI help scientists listen in on elusive Australian cockatoos
- Researchers in Australia have deployed acoustic recorders and artificial intelligence to study, monitor and protect eastern pink cockatoos (Lophochroa leadbeateri leadbeateri).
- The technology led scientists at the Queensland University of Technology to a previously unknown breeding hollow of the birds.
- Pink cockatoos, with eastern and western subspecies, are endemic to Australia and hard to monitor because they live in remote arid and semiarid ecosystems.
- With the research, scientists say they hope to understand more about where the birds live and how they react to changes in rainfall and temperature.
Wildlife from space: Winners of Satellites for Biodiversity Award named
- The winners of the second edition of the Satellites for Biodiversity Award have been announced.

- The winners of the award will be granted access to Airbus’s high-resolution satellites as well as funding and training from the Connected Conservation Foundation.
Drone cameras help scientists distinguish between drought stress & fungus in oaks
- Scientists have used remote sensing, spectroscopy and machine learning to detect sick oak trees and distinguish between drought stress and oak wilt, a fungal disease.
- A recently published study describes how researchers established a link between physiological traits of trees and light reflectance to monitor the progression of symptoms in trees afflicted by oak wilt and drought.
- They used the data to build a predictive model that can identify symptoms and detect sick oaks 12 days before visual symptoms appear.
- Oaks are vital for climate regulation and carbon sequestration; however, the trees face threats to their survival because of a fatal fungal disease as well as the worsening impacts of climate change.
New technologies to map environmental crime in the Amazon Basin (commentary)
- Environmental crimes like land grabbing, illegal deforestation, and poaching hinder climate action, deter investment in sustainable practices, and threaten biodiversity across major biomes worldwide.
- Despite challenges such as vast territories difficult to police and weak rule of law, new technologies like geospatial and predictive analytics are being leveraged to enhance the detection and disruption of these activities.
- Innovative approaches, including public-private partnerships and AI tools, show promise in improving real-time monitoring and enforcement, although they require increased investment and training to be truly effective, argue Robert Muggah and Peter Smith of Instituto Igarapé, a “think and do tank” in Brazil.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
New online tool is first to track funding to Indigenous, local and Afro-descendant communities
- The Path to Scale dashboard is the first online tool developed to track all funding for Indigenous peoples, local communities and Afro-descendant peoples’ forest stewardship and land tenure.
- It’s already highlighted several trends, including that disbursements globally have averaged $517 million per year between 2020 and 2023, up 36% from the preceding four years, but with no evidence of increased direct funding to community-led organizations.
- Although information gaps exist based on what’s publicly available, Indigenous leaders say the tool will be useful to track progress and setbacks on funding pledges, as well as hold donors and organizations accountable.
- According to developers, there’s an increased diversity of funding, but it’s still insufficient to meet the needs of communities.
The potential for tracking wildlife health & disease via bioacoustics is great (commentary)
- Bioacoustics is the passive, non-invasive recording of sounds emitted by a wide range of animals.
- Analysis of this information reveals the presence and behavior of wildlife, and can also be valuable indicator of animal health, which can then be used in ecosystem monitoring.
- “As disease prevalence skyrockets in wildlife, we are desperately in need of tools to remotely monitor ecosystem health,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
New FPIC guide designed to help protect Indigenous rights as mineral mining booms
- In the face of growing demand for critical minerals, Indigenous organizations developed a guide to help Indigenous communities implement their free, prior and informed consent (FPIC) when investors visit their lands for potential mining projects.
- Of the 30 metals and minerals needed to feed these technologies, about 54% are on and near Indigenous and peasant lands, according to a study published in Nature.
- The guide helps communities mold the FPIC framework to their governance and value systems and provides them with a “menu of options,” including preparations in advance of investor meetings, how to work through the negotiation process, steps to consider after a decision and a framework to agree on benefits of a project.
- By not following the FPIC process, companies open themselves up to operational, political, legal, reputational and investment risk when Indigenous activists protest their activities, a legal expert says.
Smaller population estimate underscores urgency of saving Cao-vit gibbon
- A recent survey based on “vocal fingerprinting” puts the total population of Cao-vit gibbons at just 74 individuals, down from previous estimates of 120.
- Researchers say the lower number represents more precise data, not an actual decline in gibbon numbers.
- However, habitat loss and hunting, along with a slow rate of reproduction, have pushed Cao-vit gibbons to the edge of extinction.
- Reforestation and establishing protected forest corridors are key to increasing population numbers, while inbreeding remains a concern for the small population.
Mining industry touts green pledges to attract talent, but Gen Z isn’t buying it
- A massive increase in renewable energy capacity will require critical minerals, such as rare earth elements, lithium, cobalt and graphite, which mining companies and governments say can create jobs and generate wealth to the benefit of communities and the environment.
- However, finding the next generation of employees appears to be a growing concern: A 2023 McKinsey report found 70% of its respondents aged 15-30 said they definitely or probably wouldn’t work in mining, and Australia has seen a 63% decrease in mining graduates from 2014 to 2020.
- Mining industry insiders and representatives say that rebranding mining from its past, in part by being more responsible as well as connecting how mined minerals can be part of the solution to net zero, will be key.
- Youth activists and community members, however, remained concerned about the persistent disconnect between mining companies’ pledges and the reality of their actions, to the detriment of people and the planet.
Japan prepares to mine its deep seabed by decade’s end
- Japan is one among just a handful of nations actively pursuing deep-sea mining within its own waters.
- The country aims to be ready to mine by the late 2020s and could be among the first nations to exploit the deep sea.
- The country has completed multiple small-scale mining tests that it claims are world firsts, and it positions itself as a global leader in the “sustainable development” of deep-sea mining.
- However, concerns about the environmental impacts of deep-sea mining have prompted widespread opposition to the practice, and one critic notes that Japan’s momentum may be too great to stop for any warning signs its research might raise.
Critics fear catastrophic energy crisis as AI is outsourced to Latin America
- AI use is surging astronomically around the globe, requiring vastly more energy to make AI-friendly semiconductor chips and causing a gigantic explosion in data center construction. So large and rapid is this expansion that Sam Altman, the boss of OpenAI, has warned that AI is driving humanity toward a “catastrophic energy crisis.”
- Altman’s solution is an audacious plan to spend up to $7 trillion to produce energy from nuclear fusion. But even if this investment, the biggest in all of history, occurred, its impact wouldn’t be felt until mid-century, and do little to end the energy and water crises triggered by AI manufacture and use, while having huge mining and toxic waste impacts.
- Data centers are mushrooming worldwide to meet AI demand, but particularly in Latin America, seen as strategically located by Big Tech. One of the largest data center hubs is in Querétaro, a Mexican state with high risk of intensifying climate change-induced drought. Farmers are already protesting their risk of losing water access.
- As Latin American protests rise over the environmental and social harm done by AI, activists and academics are calling for a halt to government rubber-stamping of approvals for new data centers, for a full assessment of AI life-cycle impacts, and for new regulations to curb the growing social harm caused by AI.
Ancient giant river dolphin species found in the Peruvian Amazon
- Paleontologists discovered a fossilized skull of a newly described species of giant freshwater dolphin in the Peruvian Amazon, which lived around 16 million years ago and is considered the largest-known river dolphin ever found.
- The ancient creature, measuring 3-3.5 meters (9.8-11.5 feet), was surprisingly related to South Asian river dolphins rather than the local, living Amazon river pink dolphin and shared highly developed facial crests used for echolocation.
- The discovery comes at a time when the six existing species of modern river dolphins face unprecedented threats, with their combined populations decreasing by 73% since the 1980s due to unsustainable fishing practices, climate change, pollution, illegal mining and infrastructure development.
- Conservation efforts are underway, including the signing of the Global Declaration for River Dolphins by nine countries and successful initiatives in China and Indonesia, highlighting the importance of protecting these critical species that serve as indicators of river ecosystem health.
Spying on wildlife with biorobots: Interview with engineer Kamilo Melo
- Biorobotics combines engineering and biology, yielding robots that can mimic biological systems.
- Biorobots can and have been used in wildlife studies to better understand animal movements, behaviors and interactions between different species.
- In 2016, engineer Kamilo Melo designed two robots, one shaped like a crocodile and the other like a monitor lizard, for the BBC nature documentary series “Spy in the Wild” that captured animal interactions in real life.
- A recent study authored by Melo documents his experience of using biorobots in the field and the scope of using biorobots for scientific research purposes.
To detect illegal roads in remote areas, AI comes into play
- Scientists have deployed an artificial intelligence model to identify and detect roads in rural and remote areas.
- The model was trained to analyze satellite images and pick out the roads within them; according to a recent study, it managed to do this accurately eight times out of 10.
- Road construction has increased drastically in recent decades, with 25 million kilometers (15.5 million miles) of paved roads expected to be built by 2050.
- Illegal roads, which fall outside the purview of environmental governance, often cut through dense forests and cause harm to the biodiversity living in fragile ecosystems.
Mini radio tags help track ‘murder hornets’ and other invasive insects
- Our increasingly interconnected world is moving insect pests around the planet, introducing invasive species that threaten agriculture and local ecologies.
- But tech is fighting back: Researchers have developed radio-tracking tags small enough to attach to invasive yellow-legged hornets in the U.K. and Europe, allowing scientists to find
and destroy their nests.
- Researchers are now deploying this technology in the U.S., to address yellow-legged hornets in Georgia and northern giant hornets in the Pacific Northwest.
Gundi tool gets conservation hardware and software talking the same language
- A new open-source platform aims to help conservationists and protected-area managers seamlessly integrate data between hardware and software tools.
- Currently being used at 600 sites, Gundi takes data from different sources — wildlife trackers, camera traps, acoustic monitors — transforms them into a common format, and sends them to different destinations for analysis.
- Gundi was developed with the goal of helping reduce the time and effort required to figure out compatibility issues between different conservation technology tools.

- The initiative supports data journalism across all of Mongabay’s languages, bureaus, and formats, including investigations, news reporting, videos, and social media visualizations. It is structured to operate across various topics and geographies, enabling comprehensive data journalism integration in all our work. It aims to elevate our storytelling by incorporating and utilizing more data as a foundational element for new stories.
New trackers bring prairie dogs’ little-known underground life to light
- Researchers have deployed a new tracker that helps them monitor prairie dogs and track their movements underground.
- The tracker uses sensors, including accelerometers and magnetometers, and combines them with GPS technology to enable researchers to retrace the trajectories of the animals.
- Prairie dogs dig up complex burrow systems and spend most of their time underground, making their movements elusive.
- During initial trials, researchers were able to use the trackers to reconstruct the trajectories of prairie dogs while they were underground.
As lightning strike fatalities increase, Bangladesh still has no reliable preventive measures
- Between 2011 and 2020, lightning strikes claimed the lives of 2,164 people, or nearly four people every week, in Bangladesh, according to the country’s disaster management department. However, a Bangladeshi NGO reports at least a thousand more lightning related fatalities between 2010 and 2021.
- Researchers linked the increased frequency of lightning with climate change; as for the increased death toll, they blamed the government’s inefficient protection measures, including the lack of tall trees.
- To reduce the number of fatalities, the government has started working on long-term solutions, such as installing lightning arresters and growing palm trees. Nevertheless, a significant sum of money is being squandered and nothing functions as expected, say experts.
Agroecological solutions better than pesticides in fighting fall armyworm, experts say
- Fall armyworm (Spodoptera frugiperda) is an invasive agricultural pest, which first hit West Africa in 2016 and quickly spread across the continent.
- Experts have now found that the pest’s impact on maize yields is no longer as severe as initially feared.
- An integrated pest management approach, prioritizing nontoxic control measures, is the best way to tackle the infestation, improve yields and protect human health, according to experts.
New funding boosts AI-enabled wildlife identification project in Australia
- An artificial intelligence project to identify native species from camera-trap images in Australia has received a A$750,000 ($492,000) grant from the government.
- The project by the conservation nonprofit Australian Wildlife Conservancy has already trained the AI model to identify 44 species from camera-trap images, from native animals such as kangaroos and dingoes, and invasive ones like cats and foxes.
- With the new funding, the team at AWC aims to scale up the model to be able to identify 120 species; the model can also be applied to alert land managers about invasive predators that are harmful to native species.
- Camera traps continue to be one of the most widely used technologies for biodiversity surveys, but the analysis of the thousands of images generated by camera traps remains a major bottleneck.
Tech to recover rainforest: Interview with Osa Conservation’s Carolina Pinto & Paulina Rodriguez
- Osa Conservation is a nonprofit organization working to monitor and protect biodiversity in the Osa Peninsula in Costa Rica.
- The peninsula is home to plants and animals seen nowhere else on the planet, and is estimated to harbor 2.5% of the global terrestrial biodiversity.
- The organization uses a wide array of tech tools — from camera traps to acoustic recorders and GPS tags — to study, monitor and protect animals such as sea turtles, jaguars and spider monkeys.
- However, the harsh terrain, weak internet connectivity and the remote nature of the ecosystem are proving to be hurdles to quicker and more efficient deployment of tech tools.
On Kaho’olawe, new technology could restore a sacred Hawaiian island
- The small Hawaiian island of Kaho‘olawe is a sacred site for Indigenous Hawaiians, who used it for navigational training, religious ceremonies, and fishing.
- But the island has faced decades of ecological destruction due to invasive plants and animals, erosion, and bombings as a test site by the U.S. military.
- A new conservation project has successfully tested a novel method using AI-equipped camera traps and an aerial drone to collect images of invasive cats, which have destroyed the island’s seabird populations, in dangerous and difficult-to-access parts of the island.
- But funding for the work on Kaho‘olawe remains scarce, and the drone project is now on hold as local organizations seek further funding to deal with the feral cats.
Find the manatee: New AI model spots sea cows from images
- A new computer model developed by engineers at the Florida Atlantic University uses deep learning to count manatees in images captured by cameras.
- The model has been trained to identify manatees in shallow waters, and can be used to identify where they aggregate, which can, in turn, be helpful to plan conservation actions and design rules for boaters and divers.
- However, the model can’t yet distinguish between adults and calves, or between males and females, both of which are details that are vital for conservation and research purposes.
- The engineering team says it plans to continue training the model in the months ahead, while also working with biologists to get their feedback on how to improve it further.
‘We’re doing so much with so little’: Interview with WildLabs’ Talia Speaker
- The use of technology for conservation and wildlife monitoring increased in recent years, with camera traps and remote sensing being the most popular tools, a report has found.
- The report by conservation technology network WildLabs also found that artificial intelligence was highly ranked for its potential impact, but was ranked low in terms of current performance because of accessibility issues.
- Marginalized groups, including women and people from lower-income countries, were found to face disproportionate barriers to accessing resources and training.
- “The motivation behind this research was to capture the experiences of the global conservation technology community, and to speak with a united voice,” says Talia Speaker, who led the research.
Scientists warn of ‘extinction crisis’ stalking Africa’s raptors
- A Nature Ecology & Evolution paper found that of 42 African raptor species, 37 had suffered a population decline over just three generations (up to 40 years).
- Raptors like secretarybirds (Sagittarius serpentarius) stand out among birds thanks to their razor-sharp vision, piercing talons and hooked beaks, making them such effective hunters of everything from other birds to mammals.
- The secretarybird, a charismatic and rare long-legged raptor that hunts on the ground, saw an 80% decline in populations in four African regions.
- The research also highlighted the grave risk to large-bodied raptor populations and the danger of some of the most threatened species being confined to protected areas.
New tool aims to help palm oil firms comply with deforestation regulations

- PlotCheck enables companies to upload plot boundaries without having to store it in the cloud, thereby working around concerns on data security and privacy.
- The tool analyzes the plot for deforestation based on publicly available satellite data; it also displays data on historical deforestation in the plot as well as palm oil processing mills in the proximity.
- “The output is going to be a statement which companies can submit to authorities to prove that their shipment is deforestation-free,” said Leo Bottrill, founder of Palmoil.io.
We need a better understanding of how crops fare under solar panels, study shows
- In agrivoltaics, farmers grow crops beneath or between solar panels.
- Proponents say the technology can help achieve clean energy goals while maintaining food production, but experts caution that careful analysis and guidelines are needed if we’re not to compromise agricultural production.
- A new synthesis of previously published studies finds that overall crop yields decline as the amount of land covered by solar panels increases.
- This ground cover ratio is a convenient, easily measured and reproducible metric that can be used to predict crop yields and better evaluate agrivoltaic systems.
‘Not the End of the World’ book assumptions & omissions spark debate
- The multiple crises the planet faces have solutions, says data scientist and head of research at Our World in Data, Hannah Ritchie.
- How to implement them remains a larger question for podcast co-host Rachel Donald, who interviewed Ritchie about her new book, “Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet.”
- In this episode, Donald challenges Ritchie on assumptions presented in the book, such as the notion that renewable energy will be adopted by low- and middle-income nations simply because it is cheaper.
- Ritchie says she intended to write an “apolitical” book, declining to discuss policy, but it’s difficult to see how many of the proposals would work without addressing geopolitical roadblocks and challenges that have repeatedly stymied these solutions.

- The team is currently working to make the model work faster and more efficiently, and to also streamline the process of gathering data.
A Mekong island too tiny for industrial farming now points to Vietnam’s future
- In the decades following the U.S. war in Vietnam, the Vietnamese government championed intensive farming methods that boosted rice harvests and turned the country into an export powerhouse.
- While much of the Mekong Delta was reshaped to support intensive farming, the coastal island of Con Chim was deemed too small to be worth installing the necessary dikes and sluice gates, leaving farmers there to continue traditional patterns of wet and dry season agriculture and fishing.
- Now, in an era dominated by climate concerns, Vietnam plans to scale back rice farming and shift to more nature-based agricultural practices. Once a forgotten backwater, Con Chim now stands as a rare guidepost to a more sustainable agricultural future.
- This story was produced in partnership with the Global Reporting Program at the University of British Columbia’s School of Journalism, Writing, and Media.

- While promising, the approach faces hurdles around privacy protections, data availability across fields, and collaboration barriers.
Where do illegal lion parts come from? A new tool offers answers
- To trace wildlife parts to their source populations, researchers at the University of Illinois Urbana-Champaign developed a web tool, the Lion Localizer, which uses DNA testing to pinpoint the geographic source of contraband lion parts.
- Its creators say the DNA-based tool is a “valuable resource for combating lion poaching, by rapidly identifying populations that are newly targeted, or that are being targeted most aggressively by poachers.”
- Most of the illicit trade feeds demand from outside the continent; demand for lion parts is high in China and Southeast Asian countries like Laos and Vietnam.
- Despite being user-friendly, the Lion Localizer can sometimes fail to generate useful information in some cases, for example where there are multiple potential source populations or because the database used to generate matches is incomplete.
A lithium ‘gold mine’ is buried under one of Europe’s last heritage farming systems
- The hilly Barroso region of northern Portugal has been recognized for its centuries-old and “globally important” farming system that combines agricultural biodiversity, resilient ecosystems and a valuable cultural heritage.
- But the region is also home to what’s believed to be one of Europe’s largest deposits of lithium, an element that will be critical in the ongoing clean energy transition, with EU and Portuguese officials saying mining projects in Barroso will be key to securing domestic supplies of the metal.
- Residents and environmental activists, however, warn the mines will scar the landscape, contaminate the water, erode the soil, disrupt local livelihoods, and deprive them of communal lands.
- Yet even as they continue to oppose the planned mines, the state can declare lithium projects to be of strategic public interest to force residents to lease the lands needed for the mining projects.
Tropical deforestation increases even as a few hotspots see respite, new data shows
- Emissions from deforestation in tropical forests rose by 5% in 2022, even as temperate forests strengthened their role as carbon sinks, according to data from a carbon mapping tool developed by nonprofit CTrees.
- According to the data, emissions from deforestation saw a dip in Indonesia and the Congo Basin in 2022; in Brazil, however, emissions continued to rise through 2022, and only started dropping this year.
- The JMRV platform uses satellite imagery and machine learning to map forests and non-forest lands around the world to monitor forest cover, carbon stocks and emissions.
- In addition to broader global data, the tool can also help local jurisdictions monitor and verify their carbon stocks to keep track of their emissions-reduction progress under the Paris climate agreement.
No animals harmed as wildlife specimen collection goes digital in 3D
- Conservationist and photographer Scott Trageser has developed a 3D scanning system that could potentially reshape how animals are studied in the wild.
- The system uses an array of cameras that work in sync to rapidly capture photos of animals in the wild, yielding a virtual 3D specimen viewable on smartphone or with a VR/AR headset.
- The noninvasive methodology will enable scientists to conduct research without euthanizing animals; digital specimens also have the advantage of not degrading over time.
- However, the high cost and technical skills required to assemble and operate the system, in addition to its inability to gather internal morphological data, are hurdles to its widespread use.
New algorithm looks at how Amazon vegetation will behave after climate change
- Brazilian scientists have pioneered a new vegetation model with a broader array of life strategies that is expected to provide a more accurate representation of the Amazon ecosystem’s functioning and the forest’s responses to climate change.
- The new model suggests that Amazon plants would reorganize, allocating more energy to their roots at the expense of stems and leaves; consequently, they would have a lower capacity to retain and absorb carbon in a scenario with reduced rainfall.
- Field research and future contributions will add new information to the model, and experts hope it will get better at predicting the future and shaping policies for conservation.
Growing rubber drives more deforestation than previously thought, study finds
- A recently published study has used high-resolution satellite data to show that deforestation linked to rubber cultivation is much higher than previously thought.
- Deforestation for rubber in Southeast Asia, which produces 90% of the world’s natural rubber, was found to be “at least twofold to threefold higher” than earlier estimates.
- The underestimation of rubber-linked deforestation has led to gaps in policy setting and implementation when it comes to managing rubber cultivation, the study says.
- While synthetic rubber, made from fossil fuels, accounts for the most of the rubber produced today, rising demand for rubber overall drove the expansion of rubber plantation areas by 3.3 million hectares (8.2 million acres) from 2010-2020.

- Considering the degree of threat facing the Amazon and its global importance, it is critical to develop better methods for monitoring and comprehending this ecosystem.
- Carlo Ratti, the director of MIT’s Senseable City Lab, and Robert Muggah, the co-founder of the Igarapé Institute, argue that creating a “digital twin” of the Amazonian ecosystem could potentially serve as a means to aid its preservation while fostering a regional bioeconomy.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
The Cloud vs. drought: Water hog data centers threaten Latin America, critics say
- Droughts in Uruguay and Chile have led residents to question the wisdom of their governments allowing transnational internet technology companies to build water-hungry mega-data centers there.
- As servers process data, they need lot of water to keep them cool. But if demand grows as expected, the world will need 10-20 times more data centers by 2035, and they’ll be using far more water. Many will likely be built in economically and water-challenged nations already facing climate change-intensified droughts.
- Latin American communities fear that this “data colonialism” will consume water they desperately need for drinking and agriculture, and are critical of their governments for giving priority treatment to transnational tech giants like Google and Microsoft, while putting people’s access to a basic human necessity at risk.
- Surging digital data use by 2030 may cause each of us in the developed world to have a “digital doppelganger,” with our internet use consuming as much water as our physical bodies. But much of the stored data is “junk.” Critics urge that nations insist on tougher regulations for transnational companies, easing the crisis.
Amid socioeconomic slump, new sugar cane varieties offer hope in Sri Lanka

Origami-inspired sensor platforms tumble like leaves to study forests
- Scientists have developed a tiny, lightweight, shape-shifting platform that can hold a variety of environmental sensors and be dropped from drones to study far-flung locations.
- The design for the platforms, known as microfliers, was inspired by origami, the Japanese art of paper folding.
- Each microflier can snap between two shapes while in the air, allowing them to have different trajectories and thus disperse across a larger area when they land.
- Though they haven’t been used in any scientific studies yet, microfliers could be useful for the large-scale deployment of environmental sensors measuring and transmitting data on pressure, temperature, humidity, or lighting conditions, among others.
Taking the global pulse of biodiversity monitoring: Q&A with Andrew Gonzalez
- A group of scientists have put forward a proposal to set up a global network that centralizes biodiversity monitoring and facilitates seamless sharing of data.
- The group wants its proposed Global Biodiversity Observing System (GBiOS) to function similarly to the network of local weather monitoring stations across the world, whose data are used to analyze and monitor climate change.
- While the technology being used to monitor biodiversity has become more sophisticated over the years, there still exists a void in getting different communities to work together to address the broader challenges in dealing with the biodiversity crisis.
- “We would not only federate people who are working together more effectively, but also fill many of the gaps in the data that currently exist in the biodiversity field,” Andrew Gonzalez, who is leading the proposal for GBiOS, told Mongabay.

- A new study has highlighted swabbing leaves as a potentially effective way to gather DNA samples of vertebrates in terrestrial ecosystems.
- Researchers identified 50 species of animals in Kibale National Park in Uganda by swabbing leaves there for a little over an hour.
- This easy and cost-effective method could potentially help scientists and wildlife managers apply environmental DNA, or eDNA, analysis more widely to terrestrial settings.
- Sampling and analysis of eDNA has been gaining popularity among researchers as an effective and non-invasive way to survey large ecosystems, especially in aquatic settings; its use in terrestrial environments has, however, faced a few restrictions.
New online map tracks threats to uncontacted Indigenous peoples in Brazil’s Amazon
- Mobi, a new online interactive map, draws information from public databases, government statistics and field observations to paint a comprehensive picture of the threats that uncontacted Indigenous peoples face in the Brazilian Amazon.
- The exact location of uncontacted communities is deliberately displaced on the map to avoid any subsequent attacks against them from those who engage in illegal activity in or near their territories.
- The tool can help Indigenous agencies deploy more effective protective actions to fend off threats such as diseases and environmental destruction, which can wipe out vulnerable populations.
- Activists hope the platform will help create a vulnerability index that ranks uncontacted populations according to the severity of threats against them, which can promote stronger public policies.
Climate change detectable in daily rainfall patterns, deep-learning model finds
- Researchers have developed a deep-learning AI model that predicts how global warming is affecting daily precipitation patterns around the world.
- Using the model, scientists found that every year since 2015 daily rainfall deviated from natural variability at least 50% of the time as a result of rising temperatures.
- Research has long focused on climate change’s long-term impacts such as annual temperature increase or precipitation rates.
- However, studies in recent years have observed how rising temperatures are altering daily weather patterns as well.
How hot are the desert tortoises getting? iButtons help find the answer
- Researchers are using a button-shaped device to gather data about desert tortoises (Gopherus agassizii) and their habitats in the Mojave Desert in Southern California.
- Using iButtons, the researchers are trying to understand how hot the tortoises get, and the temperatures that they prefer in the burrows where they spend most of their time.
- Identifying the critically endangered species’ temperature preferences is an urgent task: the tortoise faces threats to its survival from various quarters such as rising temperatures, habitat loss, and attacks by predators.
- With this research, scientists say they hope to find habitats that are safer and where the thermal conditions are suitable for the long-term survival of the tortoises.
NASA satellites reveal restoration power of beavers

- “NASA is interested in how satellite Earth observations can be used for natural resource management,” a member of the space agency’s Ecological Conservation Program tells Mongabay.
Is the genetically modified, nutrient-rich Golden Rice as safe as promised?
- In April, the Philippines’ Supreme Court heeded farmers’ and activists’ calls to look into the safety promise of Golden Rice, a genetically modified grain created to tackle the vitamin A deficiency that impacts millions, over concerns about its potential impact to rice biodiversity, farmer livelihoods and human health.
- The debate over Golden Rice is long-standing and heated, spanning two decades and primarily centered in the Philippines, where it was initially approved for commercial release.
- As legal debates over its safety promise continue, the country’s Golden Rice rollout is on track and officials aim on cultivating 500,000 hectares (1.24 million acres) of the crop by 2028.
- Mongabay spoke with health experts, Filipino officials, conservationists, farmers’ groups and civil society organizations about the contentious issue.
Sensing tech used in oil pipelines can also track Arctic sea ice, study shows
- Scientists have used undersea fiber-optic cables in the Arctic to remotely track the presence and extent of sea ice.
- Sea ice is usually monitored with the help of satellites; however, the lack of high-resolution images and the low frequency of data collection makes it difficult to do in-depth analysis.
- Using a method commonly employed to monitor oil pipelines and highways, the scientists looked for changes in signals sent down a fiber-optic cable in the Beaufort Sea that would indicate the presence of sea ice.
- While promising, the method can’t yet be used to measure the thickness of sea ice or to determine how far the ice extends to either side of the cable.
Study: Tricky balancing act between EV scale-up and mining battery metals
- A recent study finds rapidly switching to electric vehicles could significantly cut emissions but also increase demand for critical battery metals like lithium and nickel.
- Mining metals like lithium has major environmental impacts including deforestation, high water use, and toxic waste.
- Electrifying heavy-duty vehicles requires substantially more critical metals than other EVs and could account for 62% of critical metal demand in coming decades despite making up just 4-11% of vehicles.
- The researchers recommend policies to support recycling, circular economies, alternative battery chemistries, and coordinated action to balance environmental and material needs.
With fewer birds seen on farms, scientists try listening for them
- Scientists in the U.S. Midwest have piloted a methodology that combines satellite imagery and audio data to study and monitor birds in croplands.
- While remote-sensing technology helped researchers understand the attributes of the habitat, bioacoustic data aided them in identifying the birds that live there.
- Biodiversity monitoring on working lands often doesn’t get a lot of attention due to the logistical hurdles involved in accessing these often privately owned areas.
- The methods used by the scientists involved engaging with farmers and landowners to put up audio recorders in an effort to be more collaborative.
Transgenics contaminate a third of Brazil’s traditional corn in semiarid region
- A new study identified the presence of up to seven transgenic genes in single seeds of traditional, or “creole” corn from more than 1,000 samples collected in 10% of the towns in Brazil’s Caatinga.
- The results indicate cross-contamination in the fields; it is estimated that pollen from transgenic corn can travel up to 3 kilometers, contaminating nearby traditional corn crops.
- The loss of agricultural biodiversity due to contamination by transgenic plants leaves Brazil vulnerable to climate change and food insecurity. Farmers have put their faith in community creole seed banks.

In the chain of species extinctions, AI can predict the next link to break
- Scientists at Flinders University in Australia have developed a machine-learning model that predicts which species are at risk of extinction if another species is removed from an ecosystem or an invasive one is introduced.
- Trained on data on how species interact with each other, the model could serve to alert conservation managers on which vulnerable species to focus on, the developers say.
- They tested the model successfully in Australia’s Simpson Desert, where it accurately predicted which species invasive foxes and cats preyed on.
- However, the shortage of data on species interactions, along with the possible biases that arise, are gaps that still need to be filled in the model.
From grassroots to government, Singapore takes lead in tackling e-waste
- The disposal and recycling of electrical and electronic waste is a huge problem in land-starved Singapore, which generates an estimated 60,000 metric tons of e-waste annually.
- Innovative legislation enacted by Singapore’s government in 2019 puts the onus on producers to collect used electrical appliances and electronic goods and send them to sorting and recycling facilities.
- At the community level, a volunteer-driven initiative called Repair Kopitiam relies on an army of tech-savvy volunteers who work out of community centers to repair people’s old appliances and electronics.
- E-waste is the fastest-growing waste stream in the world; studies estimate e-waste generated annually will increase from 50 million metric tons today to 120 million by 2050, so lessons learned from Singapore’s groundbreaking law could guide other nations and communities around the globe to deal effectively with e-waste.
Where are the giraffes hiding? Predictive tracking tech points the way
- Researchers have combined tagging technology, satellite data and machine learning to create a model that predicts the potential locations of unknown populations of reticulated giraffes in Africa.
- The model also predicts suitable habitats where giraffes could be moved to for conservation purposes.
- Reticulated giraffes are endangered, with their populations declining due to habitat loss triggered by deforestation, urbanization and agricultural expansion.
- Findings from the model have estimated huge swaths of suitable habitats in Kenya, Ethiopia and Somalia; they’ve also contributed to the translocation of 14 giraffes to Angola, from where the animals were driven out by conflict years back.
To protect the oceans, we must map them (commentary)

- Understanding the dolphins’ movements and behaviors can aid conservation efforts to protect these endangered species, as they face various threats such as fishing entanglement, dam construction, mining, agriculture and cattle ranching.
When wildlife surveillance tech ‘watches’ people
- Conservation technologies such as camera traps, drones and acoustic sensors, are playing a greater role in protecting endangered species, preventing poaching, finding rare plants, tackling forest fires, and monitoring changes in forests and oceans.
- However, researchers and communities say these technologies are also increasingly playing a role in human surveillance, infringing on privacy, exasperating human conflicts with conservation, and posing serious social and ethical implications through their use.
- As conservation technologies increasingly monitor people much the same way CCTV cameras do, their use must be subjected to similar ethical guidelines of other public surveillance tech — which they lack, say researchers.
- Some researchers have drawn up checklists of best practices, such as getting consent from nearby communities, being transparent about how the technology will be used, not using human images opportunistically, and using tech only when there’s no alternative, less-intrusive way of collecting data.
‘Immense potential’ in tech: Q&A with Wildlife Drones CEO Debbie Saunders
- Drones have long been used to visually document and monitor wildlife, but an Australian startup is using the technology to listen for radio signals emitted from tagged wild animals.
- Wildlife Drones combines drone technology with radio telemetry to allow scientists and researchers to track the movements of birds and mammals in the wild.
- The technology, which has already been used in Vietnam, Australia, New Zealand and the U.S., enables researchers to expand the area they can monitor while tracking multiple animals at the same time.
Genetically engineered trees stoke climate hope — and environmental fears
- U.S. climate technology startup Living Carbon has been developing genetically engineered poplar trees that it says can absorb more carbon – a potential tool in the climate crisis.
- Some experts say the company lacks long-term field data and is rushing to commercialize its “supertrees,” potentially putting other species at risk.
- Despite such concerns, Living Carbon is going ahead and planting mixed forests that include its GE trees, funded by carbon offsets.
Vietnamese rice farmers go high-tech to anticipate a low-water future
- Since the 1970s, Vietnam’s “rice-first” policy facilitated the construction of an elaborate series of dikes and dams that allowed farmers in the Mekong Delta to flood their fields to allow for multiple harvests per year.
- Now, in the face of climate change impacts, seawater intrusion, upstream dams and new government policies that mandate water conservation, farmers in the delta need to find ways to reduce their water consumption.
- In one pilot project, university researchers have teamed up with local farmers to implement a technique called alternate wetting and drying (AWD), supported by a smartphone application that allows farmers to save water and reduce emissions.
A just energy transition requires better governance & equity in the DRC
- The global energy transition has increased demand for critical minerals involved in the making of products such as lithium-ion batteries, solar panels and other renewable energy sources.
- In the Democratic Republic of Congo, this demand has fueled a poorly regulated mining sector that has forced Indigenous communities off their land, polluted water and air, and given little back in the way of infrastructure or development.
- The DRC has also recently opened 27 blocks of land for oil exploration under the auspices of lifting the nation out of poverty, but our guests say the handling of these other mineral revenues doesn’t bode well for an equitable oil boom.
- Joseph Itongwa Mukumo, an Indigenous community member of Walikale in the North Kivu province and director of ANAPA-DRC, and Christian-Géraud Neema Byamungu, Francophone editor at the China Global South Project, speak with Mongabay about the impacts of mining on local and Indigenous communities and what DRC residents need for a just energy transition.
Virtual fences can benefit both ranchers and wildlife
- Virtual fencing manages livestock using GPS-linked collars to train animals to stay within a set boundary, similar to an invisible dog fence.
- Coupled with the removal of existing barbed-wire fencing, it could open up whole landscapes for wildlife by removing injurious barriers for migratory herds, reducing mortality from fence strikes for numerous bird species, and protecting sensitive habitats from trampling by cattle.
- Virtual fences are easily moved with a tap on an app, and can be used to improve pasture management through rotational grazing, reduce wildfire risk, and other benefits.
- These systems are cheaper than building and maintaining physical fences, and are already in use in the U.S., U.K., Australia and Norway.
Tag team effort brings tech to aid leatherback turtle conservation
- In Puerto Rico, scientists and conservationists are deploying drones and satellite tags to gather data about leatherback sea turtles.
- Leatherback sea turtles, the largest species of turtles in the world, have seen their populations decline due to poaching, habitat loss and bycatch in fishing nets.
- Two teams are now collaborating to use drones to identify nesting sites in Maunabo in Puerto Rico.
- They’re also tagging the animals to understand more about their migration patterns once they leave the nesting beach.
New Tree Tech: Real-time, long-term, high-tech reforestation monitoring
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- Many people see reforestation as a quick fix to the climate emergency, but tree-planting projects often fail to put in place the monitoring programs needed to track newly planted forests. Traditionally, forest monitoring has been done by hand, one tree at a time, which is extremely expensive and time-consuming.
- Satellites are mapping and remapping the entire planet daily, providing real-time data that can be used to monitor forests remotely. Drones can fly over or through forests to collect data on tree growth, bridging the gap between on-site measurements and distant satellites.
- Sensors can be installed to monitor individual trees directly, while people can collect and analyze the data electronically from a safer and easier-to-access location. Multiple sensors can form a distributed network that returns detailed information on the growth of each tree within huge reforestation plots.
Drones improve counts of rare Cao-vit gibbon, identify conservation priorities
- A survey using drones has come up with a more accurate, albeit smaller, population estimate for the critically endangered Cao-vit gibbon in the border region between Vietnam and China.
- Researchers emphasize the lower estimate isn’t the result of a population decline, citing the discovery of new gibbon groups.
- The finding, they say, “feeds into our assessments of how viable the population is [and] helps us decide what conservation actions are the most urgent.”
- The survey is the latest to underscore the “limitless” utility of drones and their growing importance in wildlife surveys and wildlife research in general.
New Tree Tech: Cutting-edge drones give reforestation a helping hand
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- Restoring hundreds of millions of hectares of lost and degraded forest worldwide will require a gigantic effort, a challenge made doubly hard by the fact that many sites are inaccessible by road, stopping manual replanting projects in their tracks.
- Manual planting is labor-intensive and slow. Drone seeding uses the latest in robotic technology to deliver seeds directly to where they’re needed. Drones can drop seeds along a predefined route, working together in a “swarm” to complete the task with a single human supervisor overseeing the process.
- Drone-dropped seed success rates are lower than for manually planted seedlings, but biotech solutions are helping. Specially designed pods encase the seeds in a tailored mix of nutrients to help them thrive. Drones are tech-intensive, and still available mostly in industrialized countries, but could one day help reseed forests worldwide.
New Tree Tech: Data-driven reforestation methods match trees to habitats
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- To create healthy, diverse ecosystems, native tree species need to be identified that will thrive at each unique site within a habitat. But with more than 70,000 tree species worldwide, gathering and analyzing the data needed to understand species’ needs, habitat preferences and limitations is no small feat.
- Environmental niche models use data on climate, soil conditions and other characteristics within a species’ range to calculate a tree’s requirements. Artificial intelligence helps sort through vast data sets to make informed predictions about the species suited to an ecosystem, now and in a warmer future.
- Biotechnology company Spades uses laboratory testing of tissue samples from plant species to quantify what growing conditions a species can tolerate and to identify its optimum growing conditions.
New Tree Tech: AI, drones, satellites and sensors give reforestation a boost
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- Current forest restoration efforts fall far short of international goals, and behind the hype lies a string of failed projects and unintended environmental consequences that have left a bad taste in the mouths of many investors, politicians and conservationists. Projects are often expensive and labor-intensive.
- Applying cutting-edge technology to the problem is helping: Advanced computer modeling and machine learning can aid tree-planting initiatives in identifying a diverse set of native species best able to thrive in unique local conditions, today and in a warming future.
- Drones are revolutionizing large-scale tree planting, especially in remote and inaccessible locations. Once trees are planted, satellite-based and on-site sensors can help monitor young forests — offering long-term scrutiny and protection often missing from traditional reforestation initiatives, and at a lower cost.
Scientists hope to tech the heck out of eDNA sampling with drones, robots
- The collection of DNA samples with the assistance of drones and robots was a recurring theme at the semifinals of a $10 million competition to identify automated rainforest conservation solutions.
- At least half of the 13 teams used drones and robots to retrieve genetic samples left behind by wildlife on tree canopies, water and air.
- As the field of environmental DNA, or eDNA, evolves, there’s rising interest in using automated technology to collect samples from difficult terrain.
- While limitations continue to exist, scientists say they’re hopeful that the gaps will be filled as the field of eDNA continues to grow.
Climate emergency may channel millions in resources toward corn-based ethanol in the Amazon
- An agribusiness magnate from the U.S., who is already the biggest producer of corn-based ethanol in Brazil, plans to leverage “green” investments from governments and banks to meet negative carbon emissions using an unproven method.
- His company is trying to implement in the Brazilian state of Mato Grosso a copy of his Midwest Carbon project, an initiative that plans to capture 12 million tons of carbon in ethanol plants and store them in North Dakota, below ground.
- Even though the company alleges that it is rigorously controlling the environmental practices of its corn suppliers in Brazil, an investigation found that the local executives are themselves connected to illegal deforestation in Mato Grosso.
Sounds of the soil: A new tool for conservation?
- Researchers are discovering that listening to the soil can be a way to understand biodiversity belowground without having to overturn every bit of the land.
- Studies have shown that soils of restored forest areas have both more complex sounds and more critters than soils of degraded sites.
- Soils of intensively managed agricultural lands, also appear to be quieter, indicating that soil sounds could be a proxy for soil health.
- Some researchers are also using sounds to identify distinct species in the soil, which could open up lots of possibilities for both pest management and wildlife conservation.
Air pollution sensors found to store crucial biodiversity data
- A team of scientists have discovered that two air quality monitoring stations in the U.K. also collected DNA samples that could benefit biodiversity monitoring.
- Scientists analyzed DNA samples trapped in the two air pollution sensors and identified 180 taxa of mammals, plants, birds and invertebrates.
- The findings signal the presence of a trove of biodiversity data hidden in air pollution sensors around the world.
- The sampling and analysis of airborne DNA is a relatively new methodology to survey biodiversity; experts say further studies are required to determine its wider applications.
Meet the tech projects competing for a $10m prize to save rainforests
- Thirteen teams took part in the semifinals of a $10 million competition that aims to identify technologies that would automate the assessment of rainforest biodiversity.
- During the semifinals in Singapore, a wide array of projects that incorporated drones, robots and machine learning were tested by the teams.
- The teams that move to the next round, to be announced in July, will get one year to improve their projects ahead of the finals in 2024.
Can an app help Liberian artisanal fishers fight illegal fishing?
- Small-scale fishers in Liberia are using a data collection platform to document cases of illegal activity at sea.
- Artisanal fishers have long borne the brunt of illegal, unreported and unregulated (IUU) fishing, some of it occurring within an inshore exclusion zone that extends 6 nautical miles from shore.
- Through the use of a mobile app called DASE, released by the NGO Environmental Justice Foundation, local fishers can geotag images and videos of incidents at sea and submit them to the National Fisheries and Aquaculture Authority for verification and possible investigation.
- Though the app has not resulted in any prosecutions yet, fishers say it is having a deterrent effect on illegal activities.
Strengthening crops with insect exoskeletons? Study says yes, by way of the soil
- Supplementing soil with insects’ cast-off outer skin after a molt can help increase plant biomass, the number of flowers, pollinator attraction, seed production, and even resilience to insect herbivore attacks, according to researchers.
- Farmers are already using insects, in particular the black soldier fly, for livestock feed and waste reduction, and this new use could help the transition to a more sustainable and circular agricultural system, scientists say.
- Along with further investments in research and development, a higher uptake in insect farming practices, by both small and industrial farmers, will improve for boosting crop productivity within circular agriculture.
New digital tool maps blue carbon ecosystems in high resolution
- The Blue Carbon Explorer, a digital tool developed by the nonprofit Nature Conservancy and the Earth-imaging company Planet, combines satellite imagery, drone footage and fieldwork to map mangroves and seagrass in the Caribbean, Papua New Guinea and Indonesia.
- The tool aims to help scientists, conservationists and governments gauge mangrove health and identify areas in need of restoration.
- The Blue Carbon Explorer comes at a time of growing interest in blue carbon ecosystems as potential nature-based solutions for climate change.
Seeking environmental DNA in Himalayan rivers: Q&A with Adarsh Man Sherchan
- Conservation geneticist Adarsh Man Sherchan is one of the leading experts keeping track of the impacts that Nepal’s dozens of dams are having on freshwater species.
- The Himalayan country has more than 120 hydroelectricity plants, many of which were built without prior aquatic biodiversity assessments.
- With advances in assessment technologies, notably environmental DNA (eDNA), and a growing cohort of trained experts like Sherchan, there’s a greater focus on identifying and mitigating the impacts of dams on river life.
- In an interview with Mongabay, Sherchan talks about why eDNA is a gamechanger for monitoring species, the process of getting eDNA samples from rivers, and why jeans and flip-flops are a no-go for fieldwork.
Competing for rainforest conservation: Q&A with XPRIZE’s Kevin Marriott
- The semifinal testing for a $10 million competition to identify technology that automates the assessment of rainforest biodiversity is underway in Singapore.
- The five-year competition is organized by California-based nonprofit XPRIZE Foundation.
- From robotic dogs to drones and novel methods to gather environmental DNA, 13 teams are competing for a place in the finals next year.
Woodpeckers for fire recovery? A new online tool tells you how
- An online tool maps and predicts the presence of black-backed woodpeckers (Picoides arcticus) in newly burned forests in California.
- The tool aims to aid fire managers in incorporating the protection of these birds into their efforts to revive burned forests.
- Black-backed woodpeckers thrive in the diverse ecosystem left behind by wildfires, but fire suppression efforts and salvage logging often disturb their habitats.
- Through the case study of black-backed woodpeckers, the tool aims to illustrate how wildlife conservation and pyrodiversity (the variation in which fires burn landscapes) should be incorporated into fire management efforts around the world.
A Twitter bot tracks meat production in the Brazilian Amazon
- An online tool developed last year by the NGO Global Witness aims to monitor and expose deforestation linked to the indirect supply chain of Brazilian meat company JBS.
- Brazil Big Beef Watch, a Twitter bot, uses satellite data and cattle transit permit data to identify whether a ranch where deforestation was detected is part of JBS’s supply chain.
- Environmentalists have often criticized JBS, the world’s biggest meat producer, for being opaque about its indirect supply chain and its inability to take action.
- The new tool, Global Witness says, aims to serve as a way to call on JBS to take action and for the company’s financers to stop backing it until JBS can prove that its supply chain is deforestation-free.
Honey production sweetens snow leopard conservation in Kyrgyzstan
- Kyrgyzstan is one of a dozen countries where snow leopards live, but its population of 300-400 of the big cats living along its highest peaks is stressed by climate change, mining, road construction, and conflict with herders, whose livestock can be tempting prey.
- A new program by two snow leopard conservation NGOs is helping herders diversify away from livestock toward beekeeping, agroecology, ecotourism and handicrafts.
- Participants receive beehives and training, and help with education and research into the local snow leopard population via deployment of many camera traps, which so far suggest that the local populations of leopards and a favorite prey species, ibex, are stable or increasing.
- Half of the honey profits are invested back into the program to improve beekeeping education, purchase supplies, and to fund environmental projects chosen by the participants.
Seafloor life abounds around hydrothermal vents hot enough to melt lead
- A team of international scientists on board the RV Falkor (too), a research vessel operated by the Schmidt Ocean Institute, recently discovered active hydrothermal vents on the Mid-Atlantic Ridge.
- This discovery was the first in more than 40 years for a 700-kilometer (423-mile) stretch of the Mid-Atlantic Ridge.
- Researchers say hydrothermal vents help regulate global ocean chemistry, support complex ecosystems, and store vast amounts of marine genetic resources.
- However, there is already interest in mining the sulfide deposits of hydrothermal vent systems for their commercially valuable minerals.
How do you study one of the world’s rarest whales?
- Researcher Dana Wright is one of a handful of scientists studying one of the world’s rarest creatures, the North Pacific right whale.
- With about 500 individuals remaining, and its eastern population that swims off the coast of North America totaling perhaps 30 individuals, it’s so rare that in a decade of research, she has yet to see a living individual of the population, though her colleagues have.
- How does one study a creature that’s so hard to document? With tools like bioacoustics, for example, and Wright has listened to tens of thousands of hours of recordings to aid the conservation of these endangered animals.
- The team continues to develop new approaches to solving the mystery of these whales’ migratory patterns and biology with a goal of identifying — and then protecting — the location of their winter calving grounds.
The more degraded a forest, the quieter its wildlife, new study shows
- Tropical forest researchers are increasingly using bioacoustics to record and analyze ecosystem soundscapes, the sounds that animals make, which in turn can be used as a proxy for forest health.
- Researchers studying soundscapes in logged rainforests in Indonesian Borneo have tested a novel approach that could provide a reliable and low-cost way for conservation agencies and communities to monitor tropical forest health.
- Their new method, which partitions animal groups into broad acoustic frequency classes, offers a stop-gap method for measuring acoustic activity that could be used in the short-term until more detailed artificial intelligence and machine-learning technology is developed.
- During their study, they found that animal sounds diminished and became asynchronous in forests disturbed by selective logging, factors that could be used as proxies for disturbed habitats.
Feathered forecast: Tech tools comb weather data for bird migrations
- Since its launch in 1999, the BirdCast project has used weather radar data to track and forecast bird migrations across the U.S.
- In recent years, technology such as cloud computing and machine learning have helped make the work of researchers in the project easier and more automated.
- Studying bird migrations is essential not only to help protect them, but to also analyze and understand environmental health.
- The BirdCast project is now working on integrating radar data with human observations and bioacoustics to help identify the bird species traversing the skies.
Return of the GEDI: Space-based, forest carbon-mapping laser array saved
- Since 2018, the GEDI mission has been firing lasers from the International Space Station to measure aboveground biomass on Earth.
- The information gleaned from it has been crucial for scientists to understand how deforestation contributes to worsening climate change.
- The mission was supposed to be decommissioned earlier this year, with the lasers fated to be jettisoned from the ISS and burned up in the atmosphere.
- However, NASA made a last-minute decision to extend the mission after a push from the scientists involved in it: the GEDI equipment will be put into storage for 18 months, then reinstated to resume operations for as long as the ISS continues to run.
Floating solar project on Philippines natural lake brings hope — and questions
- Laguna Lake in the Philippines is home to a pilot project for a floating solar photovoltaic (FPV) installation that could provide energy to surrounding communities as the country faces pressure to transition away from fossil fuels.
- “Floatovoltaic” installations already exist in other parts of Asia, but none are currently on natural lakes like Laguna; researchers say further research is needed to determine the long-term effects on the environment and local communities.
- In Laguna, local fishing communities hope their voices are heard as the project develops, especially since their livelihoods could be affected by the FPV installations; however, the project could also bring new jobs to the area.
Uterine implants and underwater ultrasounds aim to demystify shark births
- For years, studying the reproductive biology of sharks has depended on capturing the animals and dissecting them.
- Scientists recently developed the Birth Alert Tag, an egg-shaped satellite transmitter that can be implanted in the uterus of pregnant sharks to document the location and timing of births.
- In another development, scientists took ultrasound readings of whale sharks and sampled their blood to detect if they were pregnant.
- The new methods aim to help researchers determine sharks’ pregnancy status and the location of shark births; one goal is to inform the establishment of corridors to protect the animals, which are among the most vulnerable vertebrates on Earth.
As conservation technology grows, so does Mongabay’s coverage
- Mongabay’s new staff writer covering conservation technology joins the podcast to discuss this fast-growing field.
- Abhishyant “Abhi” Kidangoor has joined the newsroom after working as a reporter for Time in Hong Kong and New York, covering subjects from COVID-19 to the Hong Kong protests of 2019.
- From AI to eDNA, remote sensing and bioacoustics, Abhi discusses the range of conservation technology topics he’s tackling and what stories have surprised him the most.
Bioacoustics in your backyard: Q&A with conservation technologist Topher White
- Delta, a new eco-device, allows people to record the sounds of wildlife that live in and visit their backyards.
- Developed by conservation technologist Topher White, Delta combines the tools of bioacoustics and artificial intelligence.
- Delta is part of White’s larger mission to document the drastically changing state of global biodiversity.
To save Hainan gibbons, Earth’s rarest primate, experts roll out the big tech
- As scientists and the Chinese government ramp up efforts to protect the critically endangered Hainan gibbon, technology is playing an important part in helping track and monitor the species better.
- In recent years, bioacoustics, infrared technology and machine learning are among the tools that have been used to make data collection and analysis easier in the study of Hainan gibbons.
- According to estimates, there are only 35 or 36 individuals of the species left, limited to Bawangling National Nature Reserve in China’s Hainan province.
On wildlife and the Metaverse, some ethical considerations (commentary)
- The Metaverse may facilitate even more physical events and activities to take place online, thus cutting down on carbon emissions resulting from travel.
- But it’s also known that AI language processing models this relies on will push Metaverse carbon emissions through the roof, since they require large amounts of electricity.
- A community-driven blockchain provider and cryptocurrency option called Wild Metaverse, for example, will donate a percentage of profits to wildlife conservation. But will that be worth its overall cost to wildlife, a new op-ed wonders?
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Can gaming solve a puzzle for camera trap conservationists? (commentary)
- Artificial intelligence programs for camera trap image recognition have become quite good at identifying common wildlife, but they struggle with rare animals.
- Before AI can tell a badger from a raccoon, it needs to be trained with some images, but if a species is rarely seen in camera trap photos, there isn’t enough data for it to learn, and it won’t be very good at recognizing that rare species (‘rare-class categorization’).
- However, a new commentary explains that AI are able to learn from the kind of game engine-generated, hyper-realistic animal images that feature in today’s highly advanced digital games.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Scientists map nearly 10 billion trees, stored carbon, in Africa’s drylands
- A recent study has mapped the locations of 9.9 billion trees across Africa’s drylands, a region below the Sahara Desert and north of the equator.
- The research, which combined satellite mapping, machine learning and field measurements, led to an estimate of 840 million metric tons of carbon contained in the trees.
- This figure is much lower than the amount of carbon held in Africa’s tropical rainforests.
- However, these trees provide critical biodiversity habitat and help boost agricultural productivity, and this method provides a tool to track both degradation and tree-planting efforts in the region.
Carbon market intermediaries act with little transparency, according to report
- A new report reveals that few of the brokers, resellers and cryptocurrency vendors that act as intermediaries in the voluntary carbon market reveal the commissions and markups on the credits they buy and sell.
- This lack of transparency makes it difficult, if not impossible, to accurately assess how much money from these purchases is finding its way to climate mitigation efforts.
- The report calls on intermediaries to disclose their fees and on supporting organizations to share more information about these transactions, with the goal of illuminating the true potential impact of the voluntary carbon market on climate change.
France seeks EU okay to fund biomass plants, burn Amazon forest to power Spaceport
- As the European Union finalizes its third Renewable Energy Directive (REDIII), France is seeking an exemption to enable the European Space Agency and French Space Agency to build and operate two biomass power plants in French Guiana. An estimated 5,300 hectares of Amazon rainforest would need to be cut and biomass crops grown on the cleared land to service the power plants.
- The biomass would be burned to help power Europe’s Spaceport in French Guiana. The exemption request — which would allow EU and French public subsidies to flow to a France-based bioenergy plant builder — comes as the EU moves toward banning commodities contributing significantly to global deforestation.
- This latest move by France comes soon after it won an appeal of a 2021 court ruling in French Guiana that blocked massive Amazon clearcutting for croplands to provide liquid biofuels for three new, large power plants to make energy for the Fr. Guiana populace. Decisions on the REDIII exemption and liquid biofuels plan could come in March.
- Environmentalists are decrying the French Guiana biomass plans — and French President Emmanuel Macron’s passive support of them — not only for the Amazon deforestation it will cause, but because biomass burned to produce energy has been scientifically shown to release higher levels of carbon emissions than coal.
Machine learning makes long-term, expansive reef monitoring possible
- Conservationists can now monitor climate impacts to expansive marine ecosystems over extended periods of time, a task that used to be impossible, using a tool developed by scientists in the U.S.
- The machine learning tool, called Delta Maps, provides a new way to assess which reefs might be best suited for survival, and which play a key role in delivering larvae to others, and therefore should be targeted for preservation efforts, according to the scientists.
- The scientists used the tool to examine the impacts of climate change on connectivity and biodiversity in the Pacific Ocean’s Coral Triangle, the planet’s most diverse and biologically complex marine ecosystem.
- The authors also noted that the Coral Triangle had more opportunities for rebuilding biodiversity, thanks to the region’s dynamic climate component, than anywhere else on the planet.
Goodbye to blue skies? The trouble with engineered solutions
- Humanity has created a lot of ecological problems, and many of the proposed solutions come with giant price tags — or the things lost can even be priceless, like the sight of a blue sky — with no guarantee of solving the situation in the long term.
- Many such solutions — like Australia’s deliberate introduction of the toxic cane toad, which has wreaked havoc on the country’s wildlife — create new problems.
- Solar geoengineering to slow climate change would have the most visible effect to all, likely making the sky appear white: No more blue skies—but how would this affect the global plant community’s ability to photosynthesize, would it harm agriculture?
- Pulitzer Prize-winning author Elizabeth Kolbert joins the Mongabay Newscast to talk about her latest book, “Under a White Sky,” which examines these interventions, the problems they come with and humanity’s seeming inability to stop turning to them.
Electricity day and night: Solar power is changing isolated Amazon communities
- The Amazon region produces more than a quarter of the energy in Brazil. Still, hundreds of thousands of families are off the grid and rely on expensive diesel generators to produce electricity.
- Solar panels and other renewable energies can greatly improve the lives of people in these regions and help create jobs.
- NGOs and governments have implemented renewable energy plans in different communities in the Amazon with positive results.
- Experts agree that public policies to provide electricity in the region should also be designed to help generate new sources of income for these communities.
Carbon markets entice, but confuse, corporations: Report
- A new report from the environmental nonprofit Conservation International and the We Mean Business Coalition, a partnership of climate NGOs, found that many corporations are interested in using carbon markets to address their emissions.
- The report, released Jan. 12, drew from the responses of 502 managers in charge of sustainability at companies in the U.S., U.K. and Europe.
- Carbon markets, which allow businesses and individuals to offset their emissions by supporting projects aimed at, say, reducing tropical deforestation, are seen by some as a necessary step to reducing carbon emissions globally.
- However, others see carbon markets and the credits they sell as a tool that allows companies to continue releasing carbon with little benefit to the overall climate.
‘Grumpiest cat’ leaves its calling card on the world’s highest mountain
- The presence of the manul, a cold-adapted wild cat the size of a domestic cat, has been confirmed on the slopes of the world’s highest mountain, thanks to scat samples retrieved from there in 2019.
- The confirmation by DNA testing marks the first time the elusive cat has been formally recorded in Nepal’s eastern Himalayan region.
- The first confirmed sighting of the manul, also known as Pallas’s cat, in Nepal came in 2012, in the country’s western Himalayan region.
- Conservationists say the latest finding can help inform conservation actions for the species, including the protection of its prey.
For Tanzania’s traditional beekeepers, modern hives just don’t buzz
- Tanzanian beekeepers prefer traditional log beehives to modern hanging frame beehives, says a new study.
- Traditional beehives have a negative impact on surrounding woodlands in the country’s semiarid Chemba district, according to researchers.
- The high cost of modern hives are one deterrent to their wider adoption, but so are strong cultural attachments to traditional beekeeping.
- South African-pioneered agave log hives mimic traditional ones and could offer an alternative.
Accelerating biodiversity-positive impact: A conversation with Silverstrand Capital’s Kelvin Chiu
- Last month, delegates meeting at the United Nations Biodiversity Conference reached agreement on a plan to protect and restore 30 percent of the world’s land and ocean by 2030. The accord was widely seen as a positive development for efforts to address the global extinction crisis, which often struggles to attract the public’s attention and investment relative to climate change.
- Recognizing the importance of accelerating investment and innovation in biodiversity conservation, Silverstrand Capital–a Singapore-based family office–last year launched a program that provides capital, in-kind services and coaching, and other forms of support to companies and organizations that are developing “biodiversity-positive” solutions.
- “Climate action is important, but climate is just one aspect of planetary health,” said Silverstrand Capital’s Founder Kelvin Chiu. “Collectively we should widen our perspectives beyond carbon. Nature is inherently complex, and biodiversity as a metric captures such complexity more holistically than carbon.”
- Chiu recently spoke with Mongabay about the importance of biodiversity, obstacles in bringing biodiversity solutions to scale, and creating biodiversity-positive impact.
New app tells donors what communities need to stop deforestation: Q&A with Health In Harmony
- Nonprofit organization Health In Harmony has been working with rainforest communities to improve access to health care, education and alternative sources of income, and now has a new app to directly connect donors to communities.
- The organization aims to work on intersectional solutions to help communities improve their lives while also weaning them off practices that drive deforestation.
- Health In Harmony’s new app, which includes images and video, enables people from around the world to make donations to implement community-driven solutions.
Democratizing the deep sea: Q&A with Ocean Discovery League’s Katy Croff Bell
- The current expense of studying the deep seas stymies many research initiatives, so scientists have developed a low-cost imaging and sensor device to make access to the deep sea more equal.
- Developed using off-the-shelf hardware, “Maka Niu” can capture images and collect data on temperature and salinity down to a depth of 1,500 meters, or nearly a mile.
- Scientists in countries like the Maldives, Seychelles and South Africa are now deploying prototypes to provide feedback for the final product.
A bittersweet bioacoustics bonanza
- After six years and 150+ episodes, podcast host Mike Gaworecki is putting his microphone down. The show will go on, but will miss his expertise and command of conservation science's myriad facets.
- One of his favorite topics to cover on the show over the years has been bioacoustics, the use of acoustic recording technology to study the behavior, distribution, and abundance of wildlife.
- For his final episode hosting the Mongabay Newscast, Mike shares an array of his favorite bioacoustics interviews that illustrate the breadth and potential of this powerful conservation technology.
- Over half a million downloads later, listen to his bittersweet farewell thoughts, and the range of recordings--from forest elephants to the Big Apple's resident dolphins--he shares, here on this page, or find the Mongabay Newscast via your favorite podcast provider.
Tobacco: Vaping and smoking drive environmental harm from farm to fingertip
- Electronic cigarettes heavily marketed via single-use flavored products are increasingly popular. These products require disposal of large amounts of hazardous waste, including huge quantities of lithium, a resource in demand for electric car batteries and rechargeable electronics for laptops and mobile phones.
- Even as vaping use grows, an estimated 6 trillion “traditional” cigarettes are still smoked annually; 4.5 trillion are thought to be discarded into the environment each year. Researchers and activists emphasize that the tobacco industry is responsible for considerable harm to nature and human health.
- Traveling along the supply chain, tobacco production and consumption has consequences for forests, oceans, the climate, and for farmers and their families who produce the crop — all to an extent not yet fully known or understood.
- Efforts are underway to rein in some of these negative impacts against the backdrop of an industry accused of consistently greenwashing to conceal an environmental footprint that is harming both nature and public health.

- The Newscast also explored lesser-examined topics like cryptocurrency and their environmental impact.
- If you’re new to Mongabay’s podcast content or you want a review of some of the best recent episodes from this past year, start here.
Nations adopt Kunming-Montreal Global Biodiversity Framework
- After multiple delays due to COVID-19, nearly 200 countries at the UN Biodiversity Conference (COP15) in Montreal sealed a landmark deal to halt and reverse biodiversity loss by 2030.
- The Kunming-Montreal Global Biodiversity Framework (GBF), with four goals and 23 action-oriented targets, comes after two weeks of intense negotiations at COP15, in Montreal, Canada. This agreement replaces the Aichi Biodiversity Targets set in 2010.
- Among the 2030 goals, countries pledged to protect at least 30% of terrestrial and marine areas, while also recognizing Indigenous and traditional territories.
- Concerns have been raised about the ambitions of the framework, with many criticizing the agreement for its corporate influence, vague language and watered-down targets, many of which are not quantitative.
Airbus Foundation looks to put satellites to new biodiversity conservation uses
- The Connected Conservation Foundation and the Airbus Foundation are currently accepting proposals for an award to support the use of satellite imagery for biodiversity conservation.
- The competition winners will receive access to Airbus’s Pléiades and Pléiades Neo satellite constellations and $5,000 in financing.
- The satellites deliver images with resolutions down to 30 centimeters (12 inches) and could be used in applications such as anti-poaching, forest monitoring, and species population assessments.
Tech companies work to make fishing, aquaculture more sustainable
- Several companies around the world are developing technology to make fishing and aquaculture more sustainable.
- These include the use of artificial intelligence to identify non-native species that disrupt marine food webs and the fisheries they support, and lights that attempt to attract only target species to fishing nets in a bid to reduce the capture of non-targeted species.
- With the rapidly increasing global population underscoring the need to source protein more sustainably, experts say it’s urgent to find ways to make fishing less damaging and more productive.
Forest management tool could help rein in rampant wildlife trade in Bangladesh
- The Bangladesh Forest Department has introduced a Spatial Monitoring and Reporting Tool (SMART) to help stop wildlife trafficking in several of the country’s protected forest areas.
- The pilot program follows the success of SMART technology used in the world’s largest mangrove forest, the Sundarbans, where a University of Calcutta study shows illegal logging and poaching have dropped significantly since the introduction of the tool.
- According to the Wildlife Conservation Society, major gaps in information about wildlife trade chains hamper the government’s ability to stop wildlife crimes.
- Experts say SMART patrolling should be introduced in protected forest areas across the country.
New app transforms data gathering for wildlife in Papua New Guinea
- A new app, developed in-house, has made documenting biodiversity easier and more efficient for the staff of the Tenkile Conservation Alliance in Papua New Guinea.
- The Protected Areas Management (PAM) app allows staff to record observations while in the field, facilitating the use of photos and videos, and automatically logging other information such as location and elevation.
- Since its launch, the app has encouraged staff to record more species and has made it easier for female staff in a generally patriarchal society to document and share their findings.
- The TCA says its working to make the app available to other conservation organizations within the next year.
A new tool to peer into fishing networks: Q&A with Austin Brush of C4ADS
- Washington, D.C.-based think tank C4ADS is launching Triton, a web tool to visually display the corporate structures behind fishing vessels.
- The initial cache of data focuses on the industrial fishing fleets of five key flag states: China, Taiwan, South Korea, Spain, and Japan, which together account for most high-seas fishing.
- Understanding who owns these vessels ultimately reveals the factors driving a vessel’s movements at sea and fishing activity, according to C4ADS analyst Austin Brush.
Escape into nature’s soundscapes
- Mongabay's podcast explores the growing field of bioacoustics often, and an important subset of this discipline is soundscape recording.
- Healthy ecosystems are often noisy places: from reefs to grasslands and forests, these are sonically rich ecosystems, thanks to all the species present.
- Sound recordist George Vlad travels widely and on this special episode he plays soundscape recordings from Brazil's Javari Valley and a rainforest clearing in the Congo Basin, and describes how they were captured.
- Recording soundscapes of such places is one way to ensure we don’t forget what a full array of birds, bats, bugs, and more sounds like, despite the biodiversity crisis.
Breaking free from photosynthesis: Will high-tech foods save nature?
- Soaring industrial livestock production is dramatically increasing greenhouse gas emissions, deforestation and biodiversity loss. Current meat production methods are unsustainable and fast pushing the natural world and the global food system to the edge of collapse, argues British environmentalist George Monbiot.
- Monbiot says conventional solutions, like a global switch to veganism and/or the large-scale implementation of sustainable agroecology, are advancing too slowly to avert looming disaster. The only solutions, he says, are rapid high-tech fixes.
- The best approach, he contends, is one that would free food production from photosynthesis, using hydrogen drawn from water to feed protein- and fat-rich bacteria. The revolutionary technology can produce meat and cheese from the air that, reportedly, tastes as good as the “real” thing.
- Critical voices fear this not-yet-widely-tested techno fix may be a “magic bullet” that doesn’t work in the real world. Others say the only path to averting climate catastrophe is via mobilization around food sovereignty — the right of everyone to healthy foods produced by ecologically sound and sustainable methods, including innovations by traditional peoples.
Let’s use smart tech solutions to deal with climate change, too (commentary)
- A major solution to fix aging infrastructure to adapt to climate change realities is building smarter – not bigger.
- When it comes to choosing the right technology to implement, we should look for solutions that offer monitoring, alerting, and reporting capabilities in a secure manner.
- “Smart solutions promise a brand new world in which climate change can be mitigated by the collective [by] capturing real-time data from energy, water and waste utilities, municipalities and organizations [to] find and implement solutions that alleviate climate change-related problems,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
A flying robot swoops in via Quebec to save endangered plants in Hawai‘i
- Surveying and collecting rare plant species that grow on steep cliffs has been a risky affair for scientists and conservationists for hundreds of years.
- The world’s first aerial sampling system that comprises a robotic arm suspended from a drone is trying to solve the problem in Hawai‘i.
- Conservationists control the Mamba robotic arm via remote control to identify and cut samples from rare plant species.
- The tool has enabled scientists to collect endangered species from vertical terrain and grow them in nurseries.
LED lights could contribute to massive carbon reductions
- The world has been shifting away from wasteful incandescent and harmful fluorescent lights and increasingly adopting light-emitting diode (LED) technology, which promises to reduce carbon emissions.
- Yet despite widespread adoption of the technology, virtually no LEDs are currently recycled or reused for their parts.
- To counter this problem, researchers are exploring ways in which LEDs can be designed for reuse and repair, as well as improving the efficiency of recycling.
To get young Filipinos into farming, initiatives reach them via TikTok, school
- With the average farmer in the Philippines aged 53, and many discouraging their children from following in their footsteps, there are concerns that the country could soon face a critical shortage of people willing and able to produce the country’s food.
- Youth-led initiatives, such as Kids Who Farm and TikTok channel UrbanFarmerTV, are working to raise young people’s interest in sustainable farming techniques.
- Some lawmakers are also pushing to include agriculture studies in the high school curriculum.
To save the Amazon, scientists are listening to its rich sounds
- An unprecedented study is analyzing biodiversity by listening to nearly 16,000 minutes of recordings made in Carajás National Forest, a protected region in the Brazilian Amazon.
- Some 230 bird species have already been recognized in 7,000 minutes of recordings, in particular the white bellbird (Procnias albus) and the screaming piha (Lipaugus vociferans), the world’s two loudest birds; the next phase of the study will focus on identification of the mammals in the region.
- The study has found that the sound samples from 14 distinct locations are similar, and that the rainforest doesn’t ever sleep, with many animals vocalizing at night.
- The rainforest’s soundscape reveals information about its biodiversity, the ecosystem services it provides, and makes it possible to evaluate conservation and climate change mitigation measures.
Bangladesh e-waste rules hang in limbo as electrical goods companies ask for delay
- The Bangladesh government has failed to implement electronic waste management regulations a year after introducing a new rule that was a decade in the making.
- Countries with large stakes in Bangladesh’s electrical goods market are reportedly lobbying the World Trade Organization for a one-year delay in the implementation of e-waste regulations; meanwhile, the WTO has raised several issues with the new rule, including a reduction in the standard for lead.
- As the process stalls, e-waste continues to pile up, as the Bangladesh electrical market experiences a massive boom.
- According to a 2010 report of the Environment and Social Development Organization, more than 15% of child recycling workers in Bangladesh die during and after the effects of handling e-waste each year, and more than 83% are exposed to toxic substances.
Tuning in to the world of nonhuman sound: Q&A with author Karen Bakker
- “The Sounds of Life” is a new book by University of British Columbia geography professor Karen Bakker that explores our understanding of nonhuman sound.
- Through the stories she has gathered from around the world, Bakker reveals how new technology has given us “a planetary hearing aid,” both to better understand how nonhuman life uses sound and the ways in which these sounds can help monitor and protect species.
- Bakker also investigates the role of traditional knowledge and deep listening to help researchers tune in to the sounds around us.
- Mongabay spoke with Karen Bakker in September.
Technology makes studying wildlife easier, but access isn’t equal
- Studying primates and other wildlife in nature has long been a challenge owing to their diverse habitats and limitations on established research patterns.
- But a pair of recent studies highlights how the emergence of new technology, ranging from camera traps to drones, has made the work easier in recent years.
- Still, exorbitant costs and lack of technical know-how mean the technology isn’t easily accessible to researchers across the world.
On the roof of the world, water is life. Or a sign of it, thanks to eDNA
- A first-of-its-kind expedition in 2019 attempted to map the biodiversity on Mount Everest by using environmental DNA, or eDNA.
- With eDNA, the team was able to detect species that would have been hard to observe visually.
- The findings aim to serve as baseline data for future expeditions that study how climate change is reshaping life on the world’s highest peak.
The force is strong with space lasers helping researchers map the Amazon in 3D
- Since 2018, the GEDI mission has employed lasers on the International Space Station to measure the biomass density of forests on Earth.
- The information helps us understand how deforestation contributes to worsening climate change via increases in atmospheric concentration of carbon dioxide.
- In the Amazon rainforest, data from the mission have highlighted specific areas that could benefit from carbon-based conservation.
A millennial advocate pushes for a youth-led digital future for Indonesian fisheries
- Siti Aisyah Amini is a final-year law student who attended the World Food and Agriculture Organization’s Committee on Fisheries summit in Rome in early September.
- She served as an international representative of the International Planning Committee for Food Sovereignty’s Youth Working Group and a national representative of the Indonesian Traditional Fishers Union, or KNTI.
- The 24-year-old spoke to Mongabay Indonesia about the concerns of Indonesian fishers, and how youth and digital technology need to be involved in the industry and national fishery policies.
For lightning-prone communities in Bangladesh, new warning system may not be enough
- An average of four people a week are killed by lightning in Bangladesh, and the problem is expected to get worse as climate change increases the frequency of lightning strikes.
- Most of the victims tend to be farmers and fishers, who, like members of other poor communities around the world, are bearing the brunt of climate change impacts.
- The Bangladesh Meteorological Department has rolled out an early-warning system, based on modeling developed in collaboration with NASA, that it says will provide up to 54 hours’ warning of potential lightning strikes.
- But experts say the communities most in need of these alerts are those who don’t have access to the technology, and have called for other measures, such as building lightning arresters in open fields and wetlands, to protect vulnerable communities.
Raising awareness one bird post at a time: Q&A with Burungnesia’s Swiss Winasis
- Swiss Winasis launched the bird-spotting app Burungnesia in 2016, aiming to engage the wider public in reporting bird sightings and to raise awareness about the importance of bird conservation.
- Indonesia is a hotspot of avian biodiversity, but also a global hub of the illegal bird trade, with many species captured for the lucrative songbird market.
- To date, Burungnesia’s users have recorded some 1,300 species from around 32,000 locations, including the rediscovery of the critically endangered black-browed babbler — a species that hadn’t been seen in 170 years.
- In an interview with Mongabay, Swiss acknowledges the powerful economic incentives driving the bird trade, but says change can start at the individual level by spreading awareness.
Scientists develop AI that can listen to the pulse of a reef being restored
- Scientists have developed a machine-learning algorithm that can distinguish healthy coral reefs from less healthy ones by the soundscape in the ecosystem.
- Previous studies had established that the sounds of life in a successfully recovered reef are similar to those from a healthy reef, but parsing all the acoustic data was slow and labor-intensive.
- The new algorithm has been hailed as “an important milestone” for efficiently processing acoustic data to answer the basic question of how to determine the progress of a reef restoration program.
- Researchers say follow-up work is still needed, including to check whether the algorithm, tested in the Pacific Coral Triangle, also works in reefs in other parts of the world.
‘Remix it and let it evolve’: Q&A with FieldKit developer Shah Selbe
- Conservation technologist Shah Selbe’s plan to unveil his new environmental sensor platform FieldKit went awry because of the COVID-19 pandemic and the subsequent global supply chain crisis.
- The supply chain crisis has impacted companies big and small across industries — from Ikea to McDonalds — and been particularly harsh on smaller operators like Selbe, who don’t have the purchasing might of tech giants like Apple that are scrounging for the same scarce components.
- Selbe says that while the situation has improved somewhat, it’s still going to be hard on the conservation technology community: “Don’t build a hardware product during a pandemic,” he laughs.
- He also emphasizes the need for conservation technology to be open source to promote sharing of information: “I want people to be able to take FieldKit and mix and match and create some version of their own and build on it.”
‘Amped-up citizen science’ to save the world: Q&A with Conservation AI Hub’s Grant Hamilton
- Conservation AI Hub uses drones and artificial intelligence to detect koalas that survived the Australian bushfires of 2019 and 2020.
- The initiative is now working with communities in Australia to train them on using the technology by themselves.
- Director Grant Hamilton says it’s imperative to make technology more accessible so that more citizens can engage and participate in global conservation efforts.
In Gabon, camera-trap developers find the ideal proving ground for their craft
- Rich in forests and biodiversity, the Central African country of Gabon has long proved a fruitful testing ground for camera-trap technology.
- Snapshots of species once thought extinct in the country, such as lions, have helped inform conservation policy, including the establishment of national parks and protection of vast swaths of forest.
- The wealth of data generated means there are large data sets from various projects that researchers just don’t have the resources or time to sift through — which is why Gabon has also become a testing ground for artificial intelligence tools to aid in that task.
- Key limitations remain the cost of camera traps and the fact that many forms of data capture and analysis simply can’t be done by camera traps or AI, and still require human involvement.
Hear that? Bioacoustics is having its moment, but the technology still needs tuning
- The use of audio to study, monitor, detect and conserve species has gained popularity in recent years.
- Passive acoustic monitoring has been found to be more efficient than traditional camera traps; however, the use of audio can be data-heavy and laborious to pore through.
- Technological developments such as artificial intelligence have made audio analysis easier, but conservationists say gaps still exist.
Blockchain for conservation? Maybe, but leave the crypto out
- The increasingly popular blockchain technology is being used for conservation finance purposes, but it comes with some significant downsides, both functional and environmental.
- The “mining” process for popular cryptocurrencies, such as bitcoin, is highly energy intensive, comparable to the annual electricity usage of entire nations.
- Journalist Judith Lewis Mernit and author Brett Scott join the Mongabay Newscast to discuss these environmental impacts, complications, and the relationship of our financial systems with our ecological ones.
Beyond bored apes: Blockchain polarizes wildlife conservation community
- Blockchain technology’s various applications, such as NFTs and smart contracts, are being explored for use in wildlife conservation.
- The technology’s potential might be immense, but downsides such as a massive carbon footprint and the imposition of Western technology to dictate resource management in the Global South raise logistical and ethical questions.
- Most proponents and critics agree on one thing: The technology is still in the early stages for its applications to be fully understood and implemented on the ground.
New DNA test aims to help bust illegal trade in precious red coral
- There’s a brisk illegal trade in precious red corals, from the family Coralliidae, but law enforcement currently has a difficult time telling commonly traded taxa apart.
- Demand for the corals for use in jewelry and decorative objects has depleted certain populations of these ecosystem engineers.
- Scientists recently developed a new DNA test that could help determine whether a coral object belongs to a taxon that’s subject to international trade regulations.
- They express hope that the new method will “contribute to better control of international trade” and inform buyers about the species they purchase.
Space: New frontier for climate change & commodification, or conservation? (commentary)
- After its Cold War, militaristic origins, space exploration became an arena for scientific inquiry where courageous people have pushed the bounds of science and knowledge of our planet.
- Today’s privatization and commodification of space travel dilute this mission and will also likely cause ozone depletion and increased climate change, through the deposition of things like black carbon in the atmosphere.
- “Space is too important of an arena for science, humanity and the environmental movement to allow it to become a playground for competing billionaires,” a new op-ed argues: without robust regulation, these forces will push us away from these values of scientific research and humanitarian benefit and toward negative environmental outcomes.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Scientists strive to restore world’s embattled kelp forests
- Kelp forests grow along more than one-quarter of the world’s coastlines, and are among the planet’s most biodiverse ecosystems. But these critical habitats are disappearing due to warming oceans and other human impacts.
- Sudden recent wipeouts of vast kelp forests along the coastlines of Tasmania and California highlighted how little was known about protecting or restoring these vital marine ecosystems.
- Scientists are finding new ways to help restore kelp, but promising small-scale successes need to be ramped up significantly to replace massive kelp losses in some regions.
- Global interest in studying seaweed for food, carbon storage and other uses, may help improve wild kelp restoration methods.
In Brazil’s semiarid region, agrivoltaics show promise for food, energy security
- Recent studies have shown that agrivoltaic systems, which combine solar power generation with food farming, can be a sustainable development strategy in water-stressed regions.
- A pilot project in Brazil’s semiarid northeast region consists of a series of solar panels, underneath which vegetables can be grown and fish and chickens raised, offering both food and energy security for users.
- If scaled up, agrivoltaics could also generate electricity for the whole of Brazil, according to the project’s proponents, while at the same time boosting food production and allowing for the restoration of degraded or desertified land.
- The pilot project of the system, known as Ecolume, has shown promising results, but there has been little interest among Brazilian policymakers to replicate it more widely or even promote it as a solution for food and energy production challenges.
Data from droppings: Researchers draw up a genetic ID map for chimps
- As part of a broader project studying the cultural and genetic diversity of chimpanzees across Africa, researchers have used fecal samples from 48 sites across the continent to create a genetic identity data set of chimpanzees across the species’ range.
- The data set supports the division of chimpanzees into the four currently recognized subspecies, as well as shedding light on historic gene flow between subspecies and between chimpanzees and bonobos.
- The data set can help conservationists determine the genetic origin of chimpanzees confiscated from the illegal wildlife trade and identify poaching hotspots, researchers say.
‘Fitbit for whales’ and other tagging tech help reshape wildlife conservation
- Tagging technology has since the 1960s helped conservationists and researchers keep track of a wide range of wildlife species.
- But tags and collars can often be intrusive or invasive, acting as a source of stress to the animal and sometimes even undermining its survival.
- In recent years, researchers have developed new tag designs aimed at minimizing any impact their work might have on animals, while also providing a richer array of data.
- These solutions range from DIY radio collars made with cat collars, to bespoke tags for dolphins and whales that incorporate Apple Watch-like biometric sensors.
Bamboo mamas and bikes help with Indonesian diplomacy
- Indonesian President Joko Widodo recently gifted visiting Australian Prime Minister Anthony Albanese a bamboo bicycle during the latter’s first trip abroad since taking office.
- The publicity from the diplomatic gesture has shone a spotlight on bamboo, a versatile material once commonly used throughout Indonesia, but now largely sidelined by plastic and metal.
High tech early warning system could curb next South African locust swarms
- The worst locust swarms in South Africa’s Eastern Cape province in 25 years (occurring in May 2022) is in the past. But the millions of eggs laid by the insects could hatch this September, the beginning of spring in the Southern Hemisphere.
- Grassy farmland in the vast region was only just beginning to recover from a devastating six year drought which struck between 2015 – 2021, when the locust swarms arrived earlier this year.
- Farmers are now pinning their hopes on new software that will track newborn locusts in real time, enabling them to target and exterminate the insect pests before they take to the skies and reproduce.
- The software has been used in seven countries in the Horn of Africa and East Africa and is seen as a vital part of minimizing the size of swarms, which can become an annual disaster if they aren’t targeted immediately after birth. South Africa favors chemical pesticides over non-toxic biopesticides for locust control.
