Discarded cell phones to help fight rainforest poachers, loggers in real-time
(06/24/2014) A technology that uses discarded mobile phones to create a real-time alert system against logging and poaching will soon be deployed in the endangered rainforests of Central Africa. Rainforest Connection (RFCx), a San Francisco-based non-profit startup, is partnering with the Zoological Society of London (ZSL) to install its real-time anti-deforestation technology at sites in Cameroon. 30 RFCx devices — recycled from old Android handsets — will monitor 10,000 hectares or nearly 40 square miles of rainforest, listening for audio signals associated with logging and poaching.
Shot Egyptian vulture leads conservationists to bizarre black-market for bird parts
(06/24/2014) Around 11 AM on Thursday, 27 February 2014, Angoulou Enika was lying hidden in the tall grass on the side of a large water hole in the Sahel region of Niger. He was staying as quiet as he could while aiming his custom-made rifle at an Egyptian vulture which had landed nearby to drink from the water. He took a breath, held it and fired. The large bird fell to its side.
Using Google Earth to protect uncontacted tribes in the Amazon rainforest
(06/19/2014) In 2008, images of an uncontacted tribe in the Amazon rainforest in Brazil created ripples. With bodies painted in bright colors, members of the tribe aimed their arrows at a Brazilian government plane flying overhead, occupants of which were attempting to photograph the tribe to prove their existence. Now, a new study has found another way to survey such tribes safely and remotely—using satellite images.

Employing a single image from the WorldView2 satellite, scientists went about counting a pod of southern right whales in the Golfo Nuevo off the coast of Argentina.
New forest map for Sarawak reveals large-scale deforestation, encroachment on indigenous territories
(02/24/2014) A new online platform released by the Bruno Manser Fund reveals large-scale destruction of Sarawak's rainforests, peatlands, and traditional lands. Drawing from a variety of sources, the Sarawak Geoportal includes data on logging concessions, oil palm plantations, existing and proposed dams, historical forest cover, the extent of indigenous cultivated areas, election results, and area where there are current native customary rights (NCR) disputes.
Revolutionary Google-backed system unlocks power of 'big data' to save forests
(02/20/2014) World Resources Institute (WRI) today announced the release of a tool that promises to revolutionize forest monitoring. The platform, called Global Forest Watch and developed over several years with more than 40 partners, draws from a rich array of big data related to the word's forests and translates it into interactive maps and charts that reveal trends in deforestation, forest recovery, and industrial forestry expansion. Global Forest Watch is the first tool to monitors global forests on a monthly basis, allowing authorities and conservationists to potentially take action against deforestation as it is occurring.
Conservation groups launch new whistleblower site for wildlife and forest crimes
(02/18/2014) Welcome to Wildleaks: a new website that aims to give the global public a secure and anonymous platform to report wildlife trafficking and illegal deforestation. The illegal wildlife trade has become one of the world's largest criminal activities in recent years, decimating elephants, rhinos, tigers, primates, and thousands of lesser known species. Meanwhile, illegal logging is rampant in many parts of the world, imperiling biodiversity, undercutting locals, and robbing governments of revenue.
Tracking one of the world's last Great Indian Bustards to save the species
(02/17/2014) Bilal Habib is closely tracking the flight of a bird. Six times a day he gets its location, within a few hundred feet, through a GPS monitoring device attached to its body. One of the last members of its species, this Great Indian Bustard is part of the latest effort to save its kind from joining the ranks of other extinct birds like the dodo and the passenger pigeon.
On edge of extinction, could drones and technology save the Little Dodo?
(02/10/2014) Almost nothing is known about the little dodo, a large, archaic, pigeon-like bird found only on the islands of Samoa. Worse still, this truly bizarre bird is on the verge of extinction, following the fate of its much more famous relative, the dodo bird. Recently, conservationists estimated that fewer than 200 survived on the island and maybe far fewer; frustratingly, sightings of the bird have been almost non-existent in recent years. But conservation efforts were buoyed this December when researchers stumbled on a juvenile little dodo hanging out in a tree. Not only was this an important sighting of a nearly-extinct species, but even more so it proved the species is still successfully breeding. In other words: there is still time to save the species from extinction so long as conservationists are able to raise the funds needed.
NASA data reveals impact of cyclones on forests in Vietnam, Madagascar
(01/30/2014) Forest disturbance in Madagascar and Vietnam increased significantly in the aftermath of cyclones that hit the countries last year, according to a forest tracking tool developed by a team of NASA researchers.
Next big idea in forest conservation? Using drones to catch poachers, monitor forests
(01/24/2014) At the foothills of the Himalayas, elephants, rhinoceroses, and tigers stir in the green forests.

Sonar directly impacts whale behavior, according to military study
(12/13/2013) Noises from pile-driving, explosives, ship motors and other industrial activities have all been linked to adverse effects on marine wildlife. A new study, funded by the US Navy and published in Proceedings of the Royal Society B, suggests that military sonar may be directly impacting whale behavior. The idea that sonar might affect the behavior of whales is not new. A number of reports in the past have linked the use of military sonar to mass stranding events of beaked whales and baleen whale species.
Big data shows tropical mammals on the decline
(12/12/2013) The world's largest remote camera trap initiative—monitoring 275 species in 17 protected areas—is getting some big data assistance from Hewlett-Packard (HP). To date, the monitoring program known as the Tropical Ecology Assessment and Monitoring (TEAM) Network has taken over 1.5 million photos of animals in 14 tropical countries, but conservationists have struggled with how to quickly evaluate the flood of data.

(11/15/2013) Malaysia had the world's highest rate of forest loss between 2000 and 2012, according to a new global forest map developed in partnership with Google. Malaysia's total forest loss during the period amounted to 14.4 percent of its year 2000 forest cover. The loss translates to 47,278 square kilometers (18,244 square miles), an area larger than the country of Denmark.
Deforestation accelerates in Indonesia, finds Google forest map
(11/14/2013) Forest loss in Indonesia has sharply risen over the past 12 years, reports a new study published in the journal Science. The study, led by Matt Hansen of University of Maryland, finds that Indonesia lost 15.8 million hectares between 2000 and 2012, ranking it fifth behind Russia, Brazil, the United States, and Canada in terms of forest loss. Some 7 million hectares of forest regrew during the period.
Powered by Google, high resolution forest map reveals massive deforestation worldwide
(11/14/2013) Researchers today released a long-awaited tool that reveals the extent of forest cover loss and gain on a global scale. Powered by Google's massive computing cloud, the interactive forest map establishes a new baseline for measuring deforestation and forest recovery across all of the world's countries, biomes, and forest types. The map has far-reaching implications for efforts to slow deforestation, which accounts for roughly ten percent of greenhouse gas emissions produced by human activities, according to the authors of the paper that describes the tool and details its first findings.
Ultraviolet nets significantly reduce sea turtle bycatch
(11/11/2013) Bycatch, a side-effect of commercial fishing in which non-target species are accidentally caught, is linked to severe population declines in several species. Sea turtles are particularly impacted by small-scale coastal gillnetting practices, in which large nets are deployed and indiscriminately snag anything of a certain size that attempts to swim through them. However, that may soon change.
Seahorses on your iPad: new app allows anyone to track and document seahorses
(11/08/2013) Annually, approximately 13 million seahorses—live and dead—are traded around the globe. At this scale, the seahorse trade is potentially very destructive to a group of animals comprised of 48 species, 11 of which are listed by the International Union for Conservation and Nature (IUCN) as threatened with extinction.
Could camera trap videos galvanize the world to protect Yasuni from oil drilling?
(11/07/2013) Even ten years ago it would have been impossible to imagine: clear-as-day footage of a jaguar plodding through the impenetrable Amazon, or a bicolored-spined porcupine balancing on a branch, or a troop of spider monkeys feeding at a clay lick, or a band of little coatis racing one-by-one from the dense foliage. These are things that even researchers who have spent a lifetime in the Amazon may never see. Now anyone can: scientists at the Tiputini Biodiversity Station in Ecuador's Yasuní National Park have recently begun using camera trap videos to take movies of animals few will ever view in their lifetimes. The videos—following years of photo camera trapping—provide an intimate view of a world increasingly threatened by the oil industry.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
Scientists identify individual lizards by their irises
(10/29/2013) Institutions and governments have been scanning human irises for years to verify one's identity—Google has been using this method since 2011—but could iris-scanning be employed on other species as well? According to a new study in Amphibia-Reptila, the answer is 'yes.' Scientists have recently employed iris scanning to visually distinguish individuals of an imperiled gecko subspecies (Tarentola boettgeri bischoffi) found on Portugal's Savage Islands off the coast of Western Sahara. l.
Gold mining in the Amazon rainforest surges 400%
(10/28/2013) The extent of gold mining in the Peruvian Amazon has surged 400 percent since 1999 due to rocketing gold prices, wreaking havoc on forests and devastating local rivers, finds a new study published in the Proceedings of the National Academy of Sciences (PNAS). The assessment, led by Greg Asner of the Carnegie Institution for Science, is based on a combination of satellite imagery, on-the-ground field surveys, and an advanced airplane-based sensor that can accurately measure the rainforest canopy and sub-canopy vegetation at a resolution of 1.1 meters (42 inches).
Wildlife drones could revolutionize aerial surveys of animal populations
(09/30/2013) In open areas, like the African savannah, scientists often estimate wildlife populations through manned aerial surveys. However a new study in mongabay.com's open access journal argues that using small drones may be more cost-effective, safer, and capable of reaching more remote areas. Researchers tested the accuracy of drone counts in Bazinga Game Ranch (NGR) in Burkina Faso.
Video of Amazon gold mining devastation goes viral in Peru
(09/26/2013) Video of illegal gold mining operations that have turned a portion of the Amazon rainforest into a moonscape went viral on Youtube after a popular radio and TV journalist in Peru highlighted the story. Last week Peruvian journalist and politician Guido Lombardi directed his followers to video shot from a wingcam aboard the Carnegie Airborne Observatory (CAO), an airplane used by researchers to conduct advanced monitoring and analysis of Peru's forests. The video quickly received more than 60,000 views on Youtube.
Protecting predators in the wildest landscape you've never heard of
(09/10/2013) The Serengeti, the Congo, the Okavango Delta: many of Africa's great wildernesses are household names, however on a continent that never fails to surprise remain vast wild lands practically unknown to the global public. One of these is the Ruaha landscape: covering 51,800 square kilometers (20,000 square miles) of southern Tanzania's woodlands and savannah, Ruaha contains the largest population of elephants in East Africa, over 500 bird species, and a wealth of iconic top predators, including cheetah, hyena, wild dogs, leopard, and—the jewel in its crown—10 percent of the world's lions. But that's not all, one of Africa's least-known and secretive tribal groups, the Barabaig, also calls Ruaha home.
$450/ha tax on deforestation could help curb forest loss in Bolivia, suggests new simulation

Researchers produce the most accurate carbon map for an entire country
(07/22/2013) Researchers working in Panama have produced the most accurate carbon map for an entire country. Using satellite imagery and extremely high-resolution Light Detection and Ranging (LiDAR) data from airplane-based sensors, a team led by Greg Asner produced a detailed carbon map across the Central American country's forests. The map reveals variations in forest carbon density resulting from elevation, slope, climate, vegetation type, and canopy coverage.
Scientists build app to automatically identify species based on their calls
(07/16/2013) New technology makes it possible to automatically identify species by their vocalizations. The platform, detailed in the current issue of the journal PeerJ, has been used at sites in Puerto Rico and Costa Rica to identify frogs, insects, birds, and monkeys. Many of the animals identified by the system are typically difficult to spot in their natural environment, but audio recordings of their calls reveal not only their presence but also their activity patterns.
New forensic method tells the difference between poached and legal ivory
(07/01/2013) Forensic-dating could end a major loophole in the current global ban on ivory, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS). Scientists have developed a method to determine the age of ivory, allowing traders to tell the difference between ivory taken before the ban in 1989, which is still legal, and recently-poached ivory.
Peru opens deforestation data to the public, shows drop in Amazon forest clearing
(06/13/2013) Peru has made its comprehensive deforestation data available to the public.
NASA: Deforestation jumps in Malaysia
(06/10/2013) Deforestation jumped during the first three months of 2013 in Malaysia, Nepal and Mexico, according to a forest tracking tool developed by a team of NASA researchers.
Difference within common species may predict the presence of rare animals
(06/05/2013) When deciding whether or not to clear a patch of rainforest land for development, scientists are often called in to quantify how many different species exist there. But determining the number of rare and threatened species living in a section of jungle isn't easy. If they are very rare, the individual members of the species will be hard to find; if the area being surveyed is along a steep slope it may be difficult to access the area; if there are lots of species to identify, you might need to hire a dream team of biologists—each specialized within a different area of biodiversity—and that can get expensive. However a new study in the Proceedings of the Royal Society Journal by an international group of scientists suggests a more cost-effective and efficient way to rapidly assess local biodiversity.
Data from NASA's Landsat 8 now freely available
(06/02/2013) Data from NAA's Landsat 8 is now freely available, enabling researchers and the general public to access images captured by the satellite within twelve hours of reception. Landsat 8 launched this February and has been capturing images since April. The satellite orbits Earth every 99 minutes and captures images of every point on the planet every 16 days, beaming 400 high resolution images to ground stations every 24 hours.
Could the Tasmanian tiger be hiding out in New Guinea?
(05/20/2013) Many people still believe the Tasmanian tiger (Thylacinus cynocephalus) survives in the wilds of Tasmania, even though the species was declared extinct over eighty years ago. Sightings and reports of the elusive carnivorous marsupial, which was the top predator on the island, pop-up almost as frequently as those of Bigfoot in North America, but to date no definitive evidence has emerged of its survival. Yet, a noted cryptozoologist (one who searches for hidden animals), Dr. Karl Shuker, wrote recently that tiger hunters should perhaps turn their attention to a different island: New Guinea.
Researchers develop highest-resolution global forest cover dataset to date
(05/17/2013) Researchers at the University of Maryland have developed a 30-meter resolution forest cover data set that could boost efforts to track deforestation and forest degradation.

Brazil's satellite monitoring reduced Amazon deforestation by 60,000 sq km in 5 years
(05/08/2013) Brazil's advanced satellite monitoring system, coupled with increased law enforcement, was responsible for nearly 60 percent of the 101,000 square kilometer-drop in deforestation observed between 2007 and 2011, argues a new study published an international think tank.
Frankenfish or scientific marvel?: giant GM salmon await U.S. approval
(05/07/2013) It is hard to think of a more unlikely setting for genetic experimentation or for raising salmon: a rundown shed at a secretive location in the Panamanian rainforest miles inland and 1,500m above sea level. But the facility, which is owned by an American company AquaBounty Technologies, stands on the verge of delivering the first genetically modified food animal—a fast-growing salmon—to supermarkets and dinner tables.

(05/06/2013) Nectar-feeding bats shift the shape of their tongue to slurp up sugar from flowers upon which they feed, finds a new study published in the Proceedings of the National Academy of Sciences.
A new tool against illegal logging: tree DNA technology goes mainstream
(04/22/2013) Modern DNA technology offers a unique opportunity: you could pinpoint the origin of your table at home and track down if the trees it was made from were illegally obtained. Each wooden piece of furniture comes with a hidden natural barcode that can tell its story from a sapling in a forest all the way to your living room.
Entire planet will soon have rapid deforestation detection system
(04/09/2013) World Resources Institute (WRI) today previewed a long-awaited tool that could revolutionize global forest monitoring, reports the UN Forum on Forests, which is meeting this week in Istanbul, Turkey.
Conservation gets boost from new Landsat satellite
(04/03/2013) Efforts to monitor the world's forests and other ecosystems got a big boost in February with the launch of Landsat 8, NASA's newest earth observation satellite, which augments the crippled Landsat 7 currently orbiting Earth (technically Landsat 8 is still named the Landsat Data Continuity Mission (LDCM) and will remain so until May when the USGS turns control of the satellite over to NASA). Landsat 8/LDCM is the most advanced Earth observation satellite to date. It is the eighth Landsat since the initial launch in 1972.
Scientists a step closer toward creating biofuels directly from atmospheric CO2
(03/29/2013) Researchers have taken a step closer to using atmospheric carbon dioxide as a biofuel, potentially helping mitigate climate change while at the same time meeting rising energy demand, according to a study published in the Proceedings of the National Academy of Sciences.
Energy efficiency gains failing to keep pace with Internet's growth
(03/29/2013) Energy efficiency is failing to keep pace with the Internet's rapid rate of expansion, meaning that web use is consuming an increasing amount of energy, warns a new perspective published in the journal Science.
Male lions require dense vegetation for successful ambush hunting
(03/20/2013) For a long time male lions were derided as the lazy ones in the pride, depending on females for the bulk of hunting and not pulling their weight. Much of this was based on field observations—female lions hunt cooperatively, often in open savannah, and therefore are easier to track at night. But new research in Animal Behaviour is showing that males are adroit hunters in their own right, except prickly males hunt alone and use dense vegetation as cover; instead of social hunting in open savannah, they depend on ambushing unsuspecting prey.
Scientists successfully freeze Barbary sheep embryos for conservation purposes
(03/18/2013) The Barbary sheep (Ammotragus lervia), or aoudad, is a goat-antelope found in northern Africa. It is currently listed as Vulnerable by the IUCN Red List, with populations imperiled by hunting, habitat loss, and competition with livestock. Still little is known about its remaining population, prompting scientists in Mexico to test possible assisted reproduction of captive individuals.
Deforestation in key Madagascar park accelerated after 2009 coup d'etat, finds satellite analysis
(03/18/2013) Deforestation and forest disturbance in Madagascar's largest national park increased significantly less than a year after a coup displaced the country's democratically-elected president in 2009, finds a new study that analyzed forest cover in Masoala National Park.
A promising initiative to address deforestation in Brazil at the local level
(03/05/2013) The history of the Brazilian Amazon has long been marked by deforestation and degradation. Until recently the situation has been considered out of control. Then, in 2004, the Brazilian government launched an ambitious program to combat deforestation. Public pressure—both national and international—was one of the reasons that motivated the government to act. Another reason was that in 2004, deforestation contributed to more than 55 percent of Brazil’s total greenhouse gas emissions, making Brazil the fourth-largest greenhouse gas emitter in the world.
Frogs radio-tracked for first time in Madagascar
(03/01/2013) Researchers have radio-tracked frogs for the first time in Madagascar. Attaching tiny radio transmitters weighing 0.3-0.35 grams (1/100 of an ounce) to 36 rainbow frogs (Scaphiophryne gottlebei), the research team tracked the movement of the colorful frogs through rugged canyons in Madagascar's Isalo Massif. They found that the frogs have a short breeding period that occurs after the first intense rainfall at the start of the rainy season.
Good news about climate change? Evolving technology could make cleaning the air more profitable than fouling it
(02/26/2013) In the wake of the hottest and driest summer in memory throughout much of North America, and Super-storm Sandy that flooded cities and ravaged large swaths of the Mid-Atlantic coast, many now recognize that the climate change isn’t just real, but that it is already at our doorstep. As this realization continues to sink in, the political will may ripen to take more aggressive action to put a brake CO2 emissions. Already, President Obama, who had remained mostly silent on the issue during his reelection campaign, has made it clear that tackling climate change will be among his top second-term priorities. But the fact remains that even if the entire world switched magically to 100 percent solar and other non-polluting power sources tomorrow, it’s too late to roll back some of the impacts of climate change.
Featured video: Saving the Amazon through maps
(02/20/2013) In a new video ethnobotanist, Mark Plotkin, talks about recent—and historical—efforts to preserve the Amazon rainforest through map-making and technology. Today scientists like Plotkin are teaching indigenous people how to digitally map their territory to win land rights over the forest they've used for centuries.
NASA data registers strong deforestation signals in Sumatra, Borneo, Brazil, Gabon
(01/29/2013) NASA satellites picked up signals of extensive potential deforestation in Sumatra, Borneo, Central Africa, the Brazilian and Peruvian Amazon, the Chocó in Colombia and Ecuador, and the Chaco region of Paraguay between October 1 and December 31, 2012, according to the latest update on Mongabay.com's Global Forest Disturbance Alert System (GloF-DAS).
Illegally logged trees to start calling for help
(01/24/2013) Illegal loggers beware: trees will soon be calling—literally—for backup. The Brazilian government has begun fixing trees with a wireless device, known as Invisible Tracck, which will allow trees to contact authorities after being felled and moved.
Bloodsucking flies help scientists identify rare, hard-to-find mammals
(01/16/2013) Last year scientists released a study that is likely to revolutionize how conservationists track elusive species. Researchers extracted the recently sucked blood of terrestrial leeches in Vietnam's remote Annamite Mountains and looked at the DNA of what they'd been feeding on: remarkably researchers were able to identify a number of endangered and rarely-seen mammals. In fact two of the species gleaned from these blood-meals had been discovered by scientists as late as the 1990s. In the past, trying to find rare and shy jungle animals required many man hours and a lot of funding. While the increasing use of remote camera traps has allowed scientists to expand their search, DNA sampling from leeches could be the next big step in simplifying (and cheapening) the quest for tracking the world's mammals.
How a text message could save an elephant or a rhino from a poacher
(01/15/2013) Soon a text message may save an elephant's or rhino's life. The Kenya Wildlife Service (KWS) is implementing a new alarm system in some protected areas that will alert rangers of intruders via a text message, reports the Guardian. Elephants and rhinos have been killed in record numbers across Africa as demand for illegal rhino horns and ivory in Asia has skyrocketed.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Fires burn over a third more land than estimated
(01/02/2013) Scientists currently detect fires around the world using moderate resolution satellite imagery, however a new study in the Journal of Geophysical Research finds that this tool misses many of the world's smaller fires, which add up.
Google puts $5M toward anti-poaching drone technology
(12/18/2012) Google.org, Google Corp's philanthropic arm, earlier this month pledged $5 million toward efforts combat wildlife poaching.
Advanced technology reveals massive tree die-off in remote, unexplored parts of the Amazon
(12/12/2012) Severe drought conditions in 2010 appear to have substantially increased tree mortality in the Western Amazon, a region thought largely immune from the worst effects of changes occurring in other parts of the world's largest rainforest, reported research presented last week at the fall meeting of the American Geophysical Union (AGU). The findings suggest that the Amazon may face higher-the-expected vulnerability to climate change, potentially undercutting its ability to help mitigate greenhouse gas emissions by absorbing carbon dioxide through faster growth.
Could marine cloud machines cool the planet?
(11/26/2012) In 1990, British cloud physicist John Latham published a paper arguing he could cool global climate by brightening clouds over the ocean. Most colleagues ignored the paper, titled 'Control global warming?'—probably because this thing called global warming was not yet a hot topic. Now, more than two decades later, Latham continues to develop what has become one of the most promising and controversial ideas in climate control. 'Marine cloud brightening' might sound benign, but hairs rise when it’s called 'geoengineering.'
Cell phones help decipher malaria transmission in Kenya
(11/19/2012) Malaria parasites can stow away silently in a person’s bloodstream. Without any symptoms to betray them, their human host can unwittingly transport the parasites hundreds or thousands of miles. Tracking them has been nearly impossible, especially in poor countries. Now, researchers have harnessed a new tool: the burgeoning number of cell phone users in Africa, which help trace how malaria spreads.
Conservationists turn camera traps on tiger poachers
(11/12/2012) Remote camera traps, which take photos or video when a sensor is triggered, have been increasingly used to document rare and shy wildlife, but now conservationists are taking the technology one step further: detecting poachers. Already, camera traps set up for wildlife have captured images of park trespassers and poachers worldwide, but for the first time conservationists are setting camera traps with the specific goal of tracking illegal activity.
Strong deforestation signals from Central and West Africa in July, August, and September 2012
(11/06/2012) NASA satellites picked up signals of potential deforestation across extensive parts of Latin America, West and Central Africa, and Southeast Asia between July 1 and September 30, according to the latest update on Mongabay.com's Global Forest Disturbance Alert System (GloF-DAS).
Indonesia could plant 14.5m ha of oil palm in Borneo without further deforestation
(10/31/2012) Indonesia could establish some 14.5 million hectares of oil palm plantations in Borneo without needing to clear rainforest or high-carbon peatlands, finds a new interactive mapping tool developed by the World Resources Institute (WRI).
Will we need to pull carbon out of the atmosphere to save ourselves?
(10/17/2012) This year saw the Arctic sea ice extent fall to a new and shocking low, while the U.S. experienced it warmest month ever on record (July), beating even Dust Bowl temperatures. Meanwhile, a flood of new research has convincingly connected a rise in extreme weather events, especially droughts and heatwaves, to global climate change, and a recent report by the DARA Group and Climate Vulnerability Forum finds that climate change contributes to around 400,000 deaths a year and costs the world 1.6 percent of its GDP, or $1.2 trillion. All this and global temperatures have only risen about 0.8 degrees Celsius (1.44 degrees Fahrenheit) since the early Twentieth Century. Scientists predict that temperatures could rise between 1.1 degrees Celsius (2 degrees Fahrenheit) to a staggering 6.4 degrees Celsius (11.5 degrees Fahrenheit) by the end of the century.
Emissions from Amazon deforestation in Brazil fall 57% since 2004
(08/29/2012) Annual emissions from deforestation in the Brazilian Amazon fell by about 57 percent between 2004 and 2011, 20 percentage points lower than the recorded drop in deforestation, reports a new study published in the journal Global Change Biology by Brazilian scientists. Overall, Brazilian deforestation represented roughly 1.5 percent of global carbon emissions from human activities.
Printed petri-meat gets boost from Internet billionaire
(08/17/2012) A company attempting a new approach to in-vitro meat production received up to $350,000 from The Thiel Foundation, a philanthropy started by Internet billionaire Peter Thiel, reports CNET.
Nintendo is 'worst' company on conflict minerals
(08/16/2012) Gaming giant Nintendo is the worst company for ensuring that materials used in its electronics are not linked to bloodshed in war-torn regions like the Democratic Republic of the Congo (DRC), according to an assessment released today by the Enough Project, an initiative that aims to boost transparency around minerals sourcing.
