(11/29/2010) With world leaders meeting at climate talks in Cancun to discuss the future of forests, Google has added 3D trees to the latest version of Google Earth. Google has populated several major cities with more than 80 million virtual trees based on an automated process that identifies trees in satellite images. The realistic 3D representations are based on actual tree species found in urban areas. But Google has also extended realistic tree coverage to sites in some of the world's most biologically diverse forests.
Belize lost 10,000 ha of forest per year since 1980
(11/07/2010) Forests in Belize have been cleared at a rate of nearly 10,000 hectares per year for the past 30 years, a recent study shows. In 1980, forests covered 79.5% of the land surface of Belize but as of February 2010 it had decreased to 62.7%. The area covered by forests in the country thus went from about 6500 square miles 30 years ago to around 5300 square miles today, losing an area the size of Rhode Island.
Deforestation falls, but rainforest damage surges in Brazil in Sept

Free availability of satellite imagery has boosted deforestation monitoring applications, but risk of data gap looms
(09/29/2010) In recent years there has been an explosion in the number of satellite-based monitoring applications and technologies, which is perhaps best exemplified in the eyes of the public by Google Earth, which allows anyone with a decent internet connection to view overhead images of nearly any place on Earth. But these new applications are also helping scientists more effectively monitor environmental change, including the fluctuations in polar sea ice, shifts in oceanic plankton, and deforestation. An important factor in the expanded use of satellite imagery has been the U.S. government's free Landsat Data Distribution Policy, which allows free or inexpensive access to data captured by Landsat satellites, which have been collected data on a regular basis since 1972. But the Landsat program is not presently operating at its full capacity, increasing the risk of a 'data gap' before a new system is in place in 2012.

Amazon deforestation falls significantly in 2010, according to preliminary data
(08/31/2010) Deforestation in the Brazilian Amazon is down significantly since last year, according to preliminary estimates released by Brazil's National Institute for Space Research (INPE) and Imazon, a Brazil-based NGO that tracks forest loss and degradation across the Amazon. Analysis of NASA MODIS data by Imazon found some 1,488 square kilometers of forest were cleared during the 12 months ended July 31, 2010, down 16 percent from the same period last year, when 1,766 square kilometers were deforested. Meanwhile analysis by INPE shows an even steeper drop from 4,375 square kilometers in August 2008 through July 2009 to 2,296 square kilometers in the current period, a decline of 48 percent. The discrepancy between INPE's and Imazon's estimates results from differences in how deforestation is tracked.
80% of rainforests could adversely impacted by logging, deforestation, climate change by 2100

New protected areas in Brazil contribute to major drop in Amazon deforestation rate
(06/01/2010) Protected areas in the Brazilian Amazon are proving highly effective in reducing forest loss in Earth's largest rainforest, reports a new study based on analysis of deforestation trends in and around indigenous territories, parks, military holdings, and sustainable use reserves. The research, published in the early edition of Proceedings of the National Academy of Sciences, finds that 37 percent of the recent decline in deforestation in the Brazilian Amazon can be attributed to newly established protected areas. Brazil designated some 709,000 square kilometers (274,000 sq mi) of Amazon forest — an area larger than the state of Texas — between 2002 and 2009 under its Amazon Protected Areas Program (ARPA). Meanwhile deforestation in the Brazilian Amazon fell by nearly three-quarters between 2004 and 2009.

Brazilian tribe owns carbon rights to Amazon rainforest land
(12/09/2009) A rainforest tribe fighting to save their territory from loggers owns the carbon-trading rights to their land, according to a legal opinion released today by Baker & McKenzie, one of the world’s largest law firms. The opinion, which was commissioned by Forest Trends, a Washington, D.C.-based forest conservation group, could boost the efforts of indigenous groups seeking compensation for preserving forest on their lands, effectively paving the way for large-scale indigenous-led conservation of the Amazon rainforest. Indigenous people control more than a quarter of the Brazilian Amazon.
Ethnographic maps built using cutting-edge technology may help Amazon tribes win forest carbon payments
(11/29/2009) A new handbook lays out the methodology for cultural mapping, providing indigenous groups with a powerful tool for defending their land and culture, while enabling them to benefit from some 21st century advancements. Cultural mapping may also facilitate indigenous efforts to win recognition and compensation under a proposed scheme to mitigate climate change through forest conservation. The scheme—known as REDD for reducing emissions from deforestation and degradation—will be a central topic of discussion at next month's climate talks in Copenhagen, but concerns remain that it could fail to deliver benefits to forest dwellers.
Google – the new eye in the sky for protecting forests?
(11/22/2009) Google looks set to play a part in a called-for "new environmental world order" by satellite-monitoring the rates of deforestation of tropical rainforests and pinpointing illegal logging and land misuse, Google’s Northern and Central Europe head Philipp Schindler has revealed. Schindler made the announcement in London on November 19 at a meeting at St James's Palace hosted by the Prince's Rainforests Project about a new climate change reduction mechanism, REDD (Reduced Emissions from Deforestation and Degradation). An inter-governmental report produced this month by an Informal Working Group (IWG) for Interim Funding of REDD has outlined an initiative to save the CO2 equivalent of the annual emissions of the US over five years by rewarding developing countries for reducing deforestation, with payments on a performance basis.
Google partners with Amazon tribe

Emissions from cerrado destruction in Brazil equal to emissions from Amazon deforestation
(09/15/2009) Damage to Brazil's vast cerrado grassland results in greenhouse gas emissions equivalent to those produced by destruction of the Amazon rainforest, said Carlos Minc, the country's Environment Minister.
Brazil to step up efforts to save the cerrado grassland
(09/11/2009) Brazil will try to reduce deforestation of the cerrado, a wooded grassland ecosystem in Brazil that is being destroyed twice as fast as the Amazon rainforest, according to the country's Environment Minister Carlos Minc.
Concerns over deforestation may drive new approach to cattle ranching in the Amazon
(09/08/2009) While you're browsing the mall for running shoes, the Amazon rainforest is probably the farthest thing from your mind. Perhaps it shouldn't be. The globalization of commodity supply chains has created links between consumer products and distant ecosystems like the Amazon. Shoes sold in downtown Manhattan may have been assembled in Vietnam using leather supplied from a Brazilian processor that subcontracted to a rancher in the Amazon. But while demand for these products is currently driving environmental degradation, this connection may also hold the key to slowing the destruction of Earth's largest rainforest.
20% of land deforested in the Brazilian Amazon is regrowing forest
(09/06/2009) At least 20 percent land deforested in the Brazilian Amazon is regrowing forest, reports Brazil's National Institute for Space Research (INPE).
Is El Niño back?

Global ocean temperatures at warmest level since 1880
(07/21/2009) Global ocean temperatures rose to the warmest on record, according to data released last week by the National Oceanic and Atmospheric Administration (NOAA). The combined average global land and ocean surface temperature for June was second-warmest since global recording-keeping began in 1880. NOAA also reported a return of el Niño, raising the prospect of dryness—and risk of forest fires—in Southeast Asia.
Brazil's development bank to require beef-tracking system to avoid illegal Amazon deforestation
(07/01/2009) Responding to allegations that major Brazilian cattle producers are responsible for illegal forest clearing in the Amazon, Brazil's development bank BNDES will soon require processors to trace the origin of beef back to the ranch where it was produced in order to qualify for loans, reports Brazil's Agencia Estado. The traceability program aims to ensure that cattle products do not come from illegally deforested land.
NASA satellite photos reveal Yellowstone's recovery from fires
(06/30/2009) Satellite images released by NASA show a gradual recovery of forests affected by massive fires during the summer of 1988 in Yellowstone National Park. Fires during that hot and dry summer burned nearly 36 percent of the park — some 793,000 of the park's 2,221,800 acres.
NASA images show huge drop in Amazon fires in 2008
(06/30/2009) New NASA research shows a sharp decline in the amount of smoke over the Amazon during the 2008 burning season, coinciding with a drop in deforestation reported last week by Carlos Minc, Brazil's Environment Minister. Analyzing the aerosol concentrations over the Amazon each September from the past four burning seasons using the Ozone Monitoring Instrument on NASA's Aura satellite, atmospheric scientist Omar Torres of Hampton University and several colleagues found a dramatic decline in airborne particular matter in 2008, indicating reduced incidence of fire in the region. Fire in the Amazon is primarily used by humans for land-clearing to establish cattle pasture, which now accounts for the vast majority of land-use change in the world's largest rainforest.
Rainforest discovered via Google Earth to be protected
(06/29/2009) Mozambique has agreed to protect a tract of highland forest discovered by scientists using Google Earth, reports The Guardian.
Brazilian cattle giant declares moratorium on Amazon deforestation
(06/25/2009) Marfrig, the world's fourth largest beef trader, will no longer buy cattle raised in newly deforested areas within the Brazilian Amazon, reports Greenpeace. The announcement is a direct response to Greenpeace's Slaughtering the Amazon report, which linked illegal Amazon forest clearing to the cattle producers that supply raw materials to some of the world's most prominent consumer products companies. Marfrig was one several cattle firms named in the investigative report.
NASA photos reveal destruction of 99% of rainforest park in Rwanda
(06/09/2009) Satellite images released by NASA show nearly complete destruction of Rwanda's Gishwati Forest between 1986 and 2001. Deforestation of the forest reserve is largely the result of subsistence harvesting and cultivation by refugees in the aftermath of the country's 1994 genocide. Overall only 600 hectares of Gishwati's original 100,000 hectares of forest remain, a loss of 99.4 percent.
Destruction of Brazil's most imperiled rainforest continues
(05/31/2009) More than 100,000 hectares of Brazil's most threatened ecosystem was cleared between 2005 and 2008, reports a study by the Fundação SOS Mata Atlãntica and the National Institute for Space Research (INPE). The "Atlas of Mata Atlântica Remnants", released May 26, assessed the extent of the Mata Atlântica (Atlantic Forest) across 10 of the 17 states where the coastal rainforest occurs. It found that an 102,938 hectares were destroyed during the three year period. The annual loss of 34,121 hectares per year was 2.4 percent lower than the 34,965 ha recorded from the 2000-2005 period.
How satellites are used in conservation
(04/13/2009) In October 2008 scientists with the Royal Botanical Garden at Kew discovered a host of previously unknown species in a remote highland forest in Mozambique. The find was no accident: three years earlier, conservationist Julian Bayliss identified the site—Mount Mabu—using Google Earth, a tool that’s rapidly becoming a critical part of conservation efforts around the world. As the discovery in Mozambique suggests, remote sensing is being used for a bewildering array of applications, from monitoring sea ice to detecting deforestation to tracking wildlife. The number of uses grows as the technology matures and becomes more widely available. Google Earth may represent a critical point, bringing the power of remote sensing to the masses and allowing anyone with an Internet connection to attach data to a geographic representation of Earth.
Development of Google Earth a watershed moment for the environment
(03/31/2009) Satellites have long been used to detect and monitor environmental change, but capabilities have vastly improved since the early 1970s when Landsat images were first revealed to the public. Today Google Earth has democratized the availability of satellite imagery, putting high resolution images of the planet within reach of anyone with access to the Internet. In the process, Google Earth has emerged as potent tool for conservation, allowing scientists, activists, and even the general public to create compelling presentations that reach and engage the masses. One of the more prolific developers of Google Earth conservation applications is David Tryse. Neither a scientist nor a formal conservationist, Tryse's concern for the welfare of the planet led him develop a KML for the Zoological Society of London's EDGE of Existence program, an initiative to promote awareness of and generating conservation funding for 100 of the world's rarest species. The KML allows people to surf the planet to see photos of endangered species, information about their habitat, and the threats they face. Tryse has since developed a deforestation tracking application, a KML that highlights hydroelectric threats to Borneo’s rivers, and oil spills and is working on a new tool that will make it even easier for people to create visualizations on Google Earth. Tryse believes the development of Google Earth is a watershed moment for conservation and the environmental movement.
Deforestation maps for Sumatra now available on Google Earth
(03/31/2009) Despite many years of research in conservation biology, precise maps of tropical deforestation that document the global spatial extent of tropical forests destruction are generally not available outside of the scientific community, says David Gaveau a researcher from Durrell Institute of Conservation and Ecology (DICE) points out. For nearly seven years, Gaveau has been documenting forest destruction on the entire island of Sumatra since early 1970s using satellite technology, and he has found the way to make his full-resolution maps and scientific results public using Google Earth.
Advancements in satellite technology will help scientists and policy makers map and monitor forest carbon
(03/29/2009) Given that deforestation accounts for nearly one fifth of anthropogenic greenhouse gas emissions, reducing forest clearing and degradation is increasingly seen as an critical component to any framework addressing climate change. By some estimates, a mechanism that compensates countries for reducing emissions from deforestation and forest degradation (REDD) could funnel billions of dollars per year towards forest conservation. However the effectiveness of such a mechanism will hinge on the quality of data. Effective mapping and monitoring of forest carbon stores is absolutely key to any mechanism that compensates countries for reducing emissions from deforestation and forest degradation.
37,000 sq km of Amazon rainforest destroyed or damaged in 2008
(03/19/2009) Logging and fires damaged nearly 25,000 square kilometers (9,650 square miles) of Amazon rainforest in the August 2007-July 2008 period, an increase of 67 percent over the prior year period, according to a new mapping system developed by Brazil's National Institute for Space Research (INPE). The damage comes on top of the nearly 12,000 sq km (4,600 sq mi) of rainforest that was cleared during the year.
Carbon dioxide monitoring satellite crashes immediately after launch
(02/24/2009) The Orbiting Carbon Observatory, a $273 million satellite that would have collected measurements of carbon dioxide (CO2) in Earth's atmosphere to help better forecast the climate impacts of changes in CO2 levels, crashed about three minutes after launch, reports NASA. Researchers say the accident is a major setback for science.
