In December 2012, most part (56%) of the Legal Amazon forest area was covered by clouds. In these conditions 82 square km of deforestation were detected in the Legal Amazon. This represented a 107% increase compared to December 2011 when deforestation summed 40 square kilometers for a cloud covering of 76%.
In December 2012, most part of deforestation (57%) occurred in the State of Mato Grosso, and then of Pará (27%), Rondônia (10%) and Amazonas (6%).
Accumulated deforestation from August 2012 to December 2012 summed 1.288 square kilometers up. A 127% increase was observed compared to the former period [August 2011 to December 2011], when deforestation summed 568 square kilometers.
Degraded forests in Legal Amazon summed 261 square km in December 2012. Compared to December 2011, when the forest degradation summed 94 square kilometers, an increase of 178% was observed.
Accumulated forest degradation in the period (August 2012 to December 2012) summed 972 square kilometers. Compared to the former period (August 2012 to December 2011), when forest degradation summed 3325 square kilometers, a 71% reduction was noticed.
In December 2012, SAD detected a deforestation involving 5,5 million tons of equivalent CO2. For the accumulation of the period (from August 2012 to December 2012) the compromised equivalent CO2 emissions summed 66,5 million tons representing a 27% increase compared to the former period (August 2011 to December 2011).
