In July 2012, the Sistema de Alerta de Desmatamento (SAD – Deforestation Alert System) detected 139.5 square kilometers of deforestation in the Amazon. This represented an increase of 50% compared to July 2011 when the deforestation totaled 93.5 square kilometers. It was possible to monitor 80% of the territory, a value similar to July 2011 (82%).
The accumulated deforestation from August 2011 to July 2012 totaled 1047 square kilometers. There was a reduction of 36% over the previous period (August 2010 to July 2011) when the deforestation totaled 1,628 square kilometers.
In July 2012, the vast majority (83%) of the deforestation occurred in Pará, and in particular in the area of influence of the BR 163 (Western Pará). After appears the Mato Grosso with 10%. The remainder (7%) occurred in Rondônia (4%) and Amazonas (3%).
The degraded forests in the Amazon totaled 27.5 square kilometers in July 2012. Compared to July 2011, when the forest degradation totaled 116 square kilometers, there was a decrease of 76%. The majority (55.5%) of
this degradation occurred in Mato Grosso. Forest degradation accumulated in the period (August 2011 to July 2012) reached 2,002 square kilometers. In comparison with the previous period (August 2010 to July 2011) when the deforestation summed 6,389 square kilometers, there was a reduction of 69%. In July 2012, the deforestation detected by SAD endangered 10 million tons of CO2 equivalent.
In the accumulated of the period (August 2011 to July 2012) the CO2 equivalent emissions endangered with deforestation totaled 83.5 million tons, representing a reduction of 14% over the previous period (August 2010 to July 2011).
