INPE Has PRODES 2011 Consolidated Data

Tuesday, June 05, 2012

The Brazil’s National Institute for Space Research (Instituto Nacional de Pesquisas Espaciais - INPE) has completed the mapping and calculating of Amazon deforestation rate from August 2010 to July 2011, under the Amazon Deforestation Monitoring Project (Projeto de Monitoramento do Desflorestamento na Amazônia Legal – PRODES). The final result, obtained through analysis of 213 Landsat 5/TM images, has computed 6.418 km2.

This number is the lowest Amazon deforestation rate recorded since INPE started measuring it in 1988. PRODES recognize as deforestation areas larger than 6.25 ha that have been cleared.

The rate of deforestation consolidated by PRODES 2011 indicates a plunge of 8% over the previous period – PRODES 2010, which were measured 7.000 km2 of deforestation.

The consolidated rate is 3% higher than the estimated in December 2011, which was 6.238 km2, based on 97 Landsat images of the areas where there were recorded more than 90% of deforestation in the previous period (August/2009 to July/2010).

The chart below shows the deforestation rate in each state of Amazonia:


This outcome confirms the downward trend in the rate of Amazon deforestation that has been observed since 2005, when the PPCDAm activities were initiated, as shown in the graphs below:

(a) Average between 1977 and 1988 and (b) Average between 1993 and 1994
