Brazil’s space agency, the National Institute for Space Research (INPE), has reported the lowest rate (km²/yr) of deforestation in the Brazilian Amazon since 1988 when the agency began its annual space-based assessments.

From August 2008 to August 2009, INPE reported a deforestation rate of 7,008 square kilometers.
