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.

Palm oil giant making good on forest commitment in Indonesia, finds independent analysis
(05/29/2012) Palm oil giant PT SMART appears to be honoring its commitment to avoid conversion of high carbon forests in Indonesian Borneo, reports a new assessment published by Greenomics, an Indonesian environmental activist group. The report was issued 15 months after PT SMART — a subsidiary of Singapore-based Golden Agri Resources (GAR) and owned by Indonesia's Sinarmas Group — signed a landmark agreement with The Forest Trust (TFT) to spare forests and peatlands that have more than 35 tons of carbon per hectare. The deal came after a damaging Greenpeace campaign, which targeted PT SMART for clearing orangutan habitat in Kalimantan and cost the company millions of dollars in contracts.
Indonesia revises moratorium map; makes contested orangutan forest off-limits
(05/22/2012) Indonesia is making 'encouraging' progress on its push to reduce deforestation by improving governance over its forests and peatlands, but still needs to do more to enforce environmental laws, said the head of the country's Reducing Emissions from Deforestation and Degradation (REDD+) task force speaking at a press conference Monday in Jakarta. Kuntoro Mangkusubroto, Head of the Indonesian President’s Delivery Unit for Development Monitoring and Oversight (UKP4) and Chair of the REDD+ Task Force, said an effort to develop a map of Indonesia's forests and forest concessions has been completed, although the Ministry of Forestry has yet to deliver the map to President Susilo Bambang Yudhoyono, missing last Friday's deadline. The map serves as the basis for a two-year moratorium on new forestry concessions in primary forests and peatlands had been completed.

The lasers found that forest disturbance was actually 58 percent greater than recent satellite surveys showed, according new study in mongabay.com's open access journal Tropical Conservation Society (TCS). Such deforestation not only imperils biodiversity, carbon storage, and migration routes for Central American species, but could also lead to plundering of the Maya site of Caracol.

NASA map reveals the heights of the world's forests
(02/20/2012) The height of a forest is important in a number of different ways. First the taller a forest, the more likely there are important niche habitats in the canopy providing homes to unique species. In addition, a forests' height says something about its ability to sequester carbon: the taller a forest the more carbon it can hold. Now a team of researchers, led by NASA, has created the world's first global map showing the height of the world's forests (click here for interactive map), publishing their findings in the Journal of Geophysical Research.
Scientists create high resolution, 3D maps of forests in Madagascar

Breakthrough technology enables 3D mapping of rainforests, tree by tree
(10/24/2011) High above the Amazon rainforest in Peru, a team of scientists and technicians is conducting an ambitious experiment: a biological survey of a never-before-explored tract of remote and inaccessible cloud forest. They are doing so using an advanced system that enables them to map the three-dimensional physical structure of the forest as well as its chemical and optical properties. The scientists hope to determine not only what species may lie below but also how the ecosystem is responding to last year's drought—the worst ever recorded in the Amazon—as well as help Peru develop a better mechanism for monitoring deforestation and degradation.

Palm oil, paper drive large-scale destruction of Indonesia's forests, but account for diminishing role in economy, says report
(07/27/2011) Indonesia's forests were cleared at a rate of 1.5 million hectares per year between 2000 and 2009, reports a new satellite-based assessment by Forest Watch Indonesia (FWI), an NGO. Expansion of oil palm and wood-pulp plantations were the biggest drivers of deforestation, yet account for a declining share of the national economy. The study, which compared year 2000 data with 2009 Landsat images from NASA, found that Indonesia's forest cover declined from 103.32 million hectares to 88.17 million hectares in ten years. Since 1950 Indonesia lost more than 46 percent of its forests.

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.
