In January 2013, 61% of the forest area in Legal Amazon was covered by clouds, mainly in the states of Amapá and Pará, representing 93% and 80% of the cloud coverage, respectively. This compromised the detection of forest degradation in that month by MODIS images used by SAD. Under such conditions, only 35 square kilometers of deforestation were detected in January 2013 in Legal Amazon, what represented a 6% increase when compared to January 2012 when deforestation summed 33 square kilometers and cloud coverage was 88%.
Accumulated deforestation from August 2012 to January 2013, summed 1,305 square kilometers up, representing a 118% increase compared to the former period [August 2011 to January 2012], when deforestation summed 600 square meters.
In January 2013, a large part of deforestation (63%) occurred in the State of Mato Grosso, followed by Amazonas (12%), Pará (9%), Roraima (9%) and Rondônia (7%). Accumulated forest degradation in the
In this period (August 2012 to January 2013) summed 1041 square meters. Compared to the former period – August 2011 to January 2012, when forest degradation summed 1,433 square km, a 27% reduction was noticed.
In January 2013, SAD detected a deforestation involving 1 million tons of equivalent CO2. The accumulated of the period (from August 2012 to January 2013) of equivalent CO2 issued compromised by deforestation summed 68.5 million tons what represents a 71% increase compared to the former period (august 2012 to January 2012).
