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. Brazil uses Landsat data as a key input for their systematic monitoring of Amazonian deforestation, a project known as PRODES (Estimate of Amazon Gross Deforestation Project). From August 2008 to August 2009, INPE reported a deforestation rate of 7,008 square kilometers.
