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.

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.

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

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.
