18 May 2011 New data from the Brazilian government seem to confirm environmentalists’ fears that farmers and ranchers are clearing rainforest in anticipation of a weakening of the country’s rules governing forest protection. Wednesday, Brazil’s National Space Research Agency (INPE) announced a sharp rise in deforestation in March and April relative to the same period last year. INPE’s rapid deforestation detection system (DETER) recorded 593 square kilometers of forest clearing during the past two months, an area of rainforest 10 times the size of Manhattan and a 473 percent increase over the 103.5 sq km chopped down from March-April 2010. 81 percent of the recent clearing occurred in Mato Grosso, the southernmost state in the Brazilian Amazon that has accounted for more than 35 percent of the region’s deforestation since 1988. “The recent deforestation in Amazonia detected by INPE has been concentrated in the agricultural areas of the Mato Grosso state,” Gilberto Camara, Director of INPE, told mongabay.com. “Deforestation in these areas was high in the 1990s and early 2000s. From 2005 to 2010, due to increased law enforcement and private arrangements such as the Soy Moratorium, these areas had a substantial reduction on forest clearings.”INPE’s announcement comes a day after Imazon, a research institute that also tracks deforestation, reported a big percent increase in clear-cutting. Imazon also found a surge in forest degradation, the logging, burning, and thinning of forest that often precedes deforestation. …
