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.

Zero net deforestation is the wrong target, warn experts
(11/14/2013) Environmental initiatives that target zero net deforestation may miss their mark when it comes to slowing climate change and protecting biodiversity, warns a commentary published in this week's issue of the journal Science. While zero net deforestation may seem like a worthy target in efforts to curb forest loss, Sandra Brown and Daniel Zarin argue that the goal is at best, ambiguous, and at worst, may lead to perverse outcomes for the world's forests.
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.

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.

(07/30/2012) Ten tropical African countries will receive training and support to develop national forest monitoring systems, reports the United Nations. Brazil, which has an advanced deforestation tracking system, will guide the initiative in partnership with the Central Africa Forests Commission (COMIFAC) and the UN Food and Agriculture Organization (FAO).
165,000 sq km of Colombian rainforest mapped in stunning detail using lasers, satellites
(07/25/2012) Scientists have created high-resolution carbon maps for 165,000 square kilometers (64,000 square miles) of forest across roughly 40 percent of the Colombian Amazon, greatly boosting the ability of the South American nation to measure emissions from deforestation and forest degradation, reports the Carnegie Institution for Science at Stanford University, which led the effort.
Pictures: 40 years of NASA's Earth-observing satellite program
(07/25/2012) Landsat, NASA's Earth-observing satellite program, turned 40 on Monday. The space agency celebrated by releasing some of the program's best images showing how landscapes have changed in the past 40 years, including the five most popular 'Earth as Art' images.
Map reveals sharp increase in U.S. fires since 2001
(07/24/2012) A new map using NASA data reveals an increase in the severity of fires in the United States since 2000.
Record 97 percent of Greenland's ice sheet experienced melting in July
(07/24/2012) 97 percent of Greenland's ice sheet experienced some degree of melting this July, a record extent of melt, says NASA.
Past climate change reduced lemur population in Madagascar
(07/24/2012) Climate change that took place 4,000-10,000 years ago may have contributed to the endangered status of one of Madagascar's rarest lemurs by reducing the extent of its habitat, argues a new study published in the journal Proceedings of the Natural Academy of Sciences.
NASA satellites register deforestation hotspots in Cambodia, Myanmar, Ecuador for Apr-Jun 2012 period
(07/19/2012) NASA satellites picked up extensive signals of potential deforestation across large parts of the tropics between April 1, 2012 and June 30, 2012, according to the latest update on Mongabay.com's Global Forest Disturbance Alert System.
Charts: deforestation in Indonesia and Malaysia, 2000-2010
(07/15/2012) Indonesia and Malaysia lost more than 11 million hectares (42,470 square miles) of forest between 2000 and 2010, according to a study published last year in the journal Global Change Biology. The area is roughly the size of Denmark or the state of Virginia. The bulk of forest loss occurred in lowland forests, which declined by 7.8 million hectares or 11 percent on 2000 cover. Peat swamp forests lost the highest percentage of cover, declining 19.7 percent. Lowland forests have historically been first targeted by loggers before being converted for agriculture. Peatlands are increasingly converted for industrial oil palm estates and pulp and paper plantations.
Indonesia, Brazil, Mexico, Peru get big boost in deforestation tracking, biomass measurement
(07/11/2012) Efforts to rapidly and accurately track deforestation and forest degradation in Indonesia, Brazil, Mexico, and Peru got a boost this week with a special technical training session organized by the Governors Climate and Forest Task Force. The meeting, convened at Stanford University and Google's Silicon Valley campus, paired staffers from government agencies and NGOs in the four tropical countries with technical experts from the Amazon Environmental Research Institute (IPAM), the Carnegie Institution for Science, the Forum on Readiness for REDD, Woods Hole Research Center, and Google Earth Outreach. The participants received training to augment existing deforestation, forest degradation and biomass monitoring capabilities, which are highly variable both between countries and within sub-national agencies and jurisdictions.
Remote-controlled model planes offer bird's-eye approach to conservation
(07/10/2012) Inexpensive aerial drones can help conservationists map forests, monitor land use change like deforestation, and track wildlife in remote and inaccessible areas, reports a new study published in the journal Tropical Conservation Science.
New geojournalism mapping platform for the Amazon
(06/21/2012) A new mapping platform combines georeferenced environmental news articles with data on deforestation, fires, protected areas, and oil and gas concessions in the Amazon.
Deforestation accounts for 10 percent of global carbon emissions, argues new study
(06/21/2012) Tropical deforestation accounted for 10 percent of global carbon dioxide emissions between 2000-2005 — a substantially smaller proportion than previously estimated — argues a new study published in Science. The paper estimates gross carbon emissions from deforestation at 810 million metric tons (with a 90 percent confidence interval of 0.57-1.22 billion tons) per year from 2000-2005, significantly below earlier calculations. Brazil and Indonesia accounted for 55 percent of gross emissions from tropical deforestation during the study period, while dry forests accounted for 40 percent of tropical forest loss but amounted to only 17 percent of emissions.
