New global carbon map for 2.5 billion ha of forests
(05/31/2011) Tropical forests across Latin America, Africa, and Southeast Asia stored 247 gigatons of carbon — more than 30 years' worth of current emissions from fossil fuels use — in the early 2000s, according to a comprehensive assessment of the world's carbon stocks. The research, published in the journal Proceedings of the National Academy of Sciences by an international team of scientists, used data from 4,079 plot sites around the world and satellite-based measurements to estimate that forests store 193 billion tons of carbon in their vegetation and 54 billion tons in their roots structure. The study has produced a carbon map for 2.5 billion ha (6.2 billion acres) of forests.
Destruction of Brazil's most endangered forest, the Mata Atlantica, slows
(05/27/2011) Deforestation of Brazil's most threatened forest ecosystem dropped substantially during the 2008-2010 period according to new data released by Brazil's National Institute for Space Research (INPE) and Fundação SOS Mata Atlântica. Analysis of satellite images across 16 of the 17 states the Atlantic Forest spans found that 312 square kilometers of forest was cleared between 2008 and 2010, down from 1,029 square kilometers between 2005 and 2008. Deforestation was concentrated in the states of Minas Gerais, Bahia, Santa Catarina and Parana.

Google Earth animation reveals Indonesian forest targeted for destruction by pulp and paper companies
(05/14/2011) A new animation created using Google Earth offers a tour of an area of forest slated for destruction by logging companies. The animation, created by WWF-Indonesia and David Tryse, with technical assistance from Google Earth Outreach, highlights the rainforest of the Bukit Tigapuluh landscape in Sumatra, the only island in the world that is home to Sumatran tigers, elephants, rhinos, and orangutans. All of these species are considered endangered or critically endangered due to habitat destruction or poaching.
Election cycle linked to deforestation rate in Indonesia
(04/14/2011) Increased fragmentation of political jurisdictions and the election cycle contribute to Indonesia's high deforestation rate according to analysis published by researchers at the London School of Economics (LSE), the Massachusetts Institute of Technology (MIT), and South Dakota State University (SDSU). The research confirms the observation that Indonesian politicians in forest-rich districts seem repay their election debts by granting forest concessions.

Indonesian Borneo and Sumatra lose 9% of forest cover in 8 years
(02/25/2011) Kalimantan and Sumatra lost 5.4 million hectares, or 9.2 percent, of their forest cover between 2000/2001 and 2007/2008, reveals a new satellite-based assessment of Indonesian forest cover. The research, led by Mark Broich of South Dakota State University, found that more than 20 percent of forest clearing occurred in areas where conversion was either restricted or prohibited, indicating that during the period, the Indonesian government failed to enforce its forestry laws.
Monitoring deforestation: an interview with Brazilian space researcher Gilberto Camara
(02/08/2011) Perhaps unsurprisingly, the world's best deforestation tracking system is found in the country with the most rainforest: Brazil. Following international outcry over immense forest loss in the 1980s, Brazil in the 1990s set in motion a plan to develop a satellite-based system for tracking changes in forest cover. In 2003 Brazil made the system available to the world via its web site, providing transparency on an issue that was until then seen as a badge of shame by some. Since then Brazil has become recognized as the standard-bearer for deforestation tracking and reporting—no other country offers the kind of data Brazil provides. Space engineer Gilberto Camara has overseen much of INPE's earth sensing work and during his watch, INPE has released several new exciting capabilities.
Burning up biodiversity: forest fires increase in Madagascar
(01/10/2011) The number of fires burning in and around forests in the northeastern part of Madagascar increased during the 2010 burning season relative the the year before, according to analysis of NASA data by WildMadagascar.org / Mongabay.com.

New data shows REDD+ is succeeding
(12/15/2010) Amid the whirlwind of climate change news before and after the Cancún climate conference, including a landmark agreement on REDD+ (reducing emissions from deforestation, and related pro-forest actions), an important story seems to have passed by with little notice. Over the past two months, several new analyses have given clear evidence that deforestation has gone down over the past several years. In fact, the drop is quite impressive, and shows that of all the approaches to avoiding the worst consequences of global warming, reducing tropical deforestation is the one that has contributed by far the most to date.

Less than 8 percent of the Atlantic forest—famed for its biodiversity—remains.
Pulp plantations destroying Sumatra's rainforests
(11/30/2010) Indonesia's push to become the world's largest supplier of palm oil and a major pulp and paper exporter has taken a heavy toll on the rainforests and peatlands of Sumatra, reveals a new assessment of the island's forest cover by WWF. The assessment, based on analysis of satellite imagery, shows Sumatra has lost nearly half of its natural forest cover since 1985. The island's forests were cleared and converted at a rate of 542,000 hectares, or 2.1 percent, per year. More than 80 percent of forest loss occurred in lowland areas, where the most biodiverse and carbon-dense ecosystems are found.
Google Earth now features 3-D trees
(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.

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.

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.
