In October 2012, SAD has detected 487 square km of deforestation in the Legal Amazon. This represented a 377% increase compared to October 2011 when deforestation summed 108 square kilometers up. Due to cloud covering it was possible to monitor 83% of the territory, an amount quite higher than October 2011 (51%).
Accumulated deforestation from August 2012 to October 2012, summed 1,151.6 square kilometers up. A 125% increase was observed compared to the former period [August 2011 to October 2011], when deforestation summed 511 square meters.
In October 2012, a little over a third (36%) of deforestation occurred in the State of Pará, and a little less (30%) in the State of Mato Grosso. The remaining occurred in Amazonas [17%), Rondônia (12%) and other states (Acre, Tocantins and Roraima)
Degraded forests in Legal Amazon summed 266.5 square km in October 2012. Compared to October 2011, a reduction of 42% was observed, when forest degradation summed 456 square kilometers.
Accumulated forest degradation in the period from August 2012 to October 2012 summed 611 square meters. Compared to the former period – August 2011 to October 2011, when forest degradation summed 1,245 square km, a 51% reduction was noticed.
In October 2012, SAD detected a deforestation involving 26 million tons of equivalent CO2. The accumulated of the period (from August 2012 to October 2012) of equivalent CO2 issued compromised by deforestation summed 57 million tons what represents a 27% increase compared to the former period (august 2011 to October 2011).
