Hayashi, S., Souza Jr, C., Sales, M. & Veríssimo, A. Forest Transparency Report for The Brazilian Amazon. Imazon. 2011.
In November 2011, most part (71 %) of the forest area of Legal Amazon were covered by clouds. This compromised the detection of the deforestation and forest degradation for this month through the images of the MODIS used by SAD. Only 16 km² of deforestation were detected in November 2011 in Legal Amazon under these conditions.
From the 16 km² of deforestation detected in November 2011, 9 square kilometers (59%) occurred in Amazonas, 4 square kilometers (24%) in Pará, 2 square kilometers (12%) in Mato Grosso, and less than 1 square kilometers in Rondônia and Acre.
The deforestation accumulated in the period of August 2011 to November 2011, corresponding to the first four months of the current Deforestation Calendar, has reached 527 square kilometers. There was a 12% reduction regarding the same previous period (August 2010 to November 2010) when the deforestation totaled 597 square kilometers.
The degraded forests in Legal Amazon totaled 40 square kilometers in November 2011. Most part (63%) occurred in Mato Grosso followed by Pará (16%), Rondônia (16%) and Amazonas (5%).
The forest degradation accumulated in the period of August 2011 to November 2011 totaled 1.285 square kilometers. Regarding the previous period (August 2010 to November 2010) there was a reduction of 54%, when the forest degradation totaled 2.787 square kilometers.
In November 2011, the deforestation detected by SAD compromised 2.5 million tons of equivalent CO2. In the accumulated period (August 2011 – November 2011) the emission of equivalent CO2 related to the deforestation totaled 34 million tons which represents a reduction of 4% regarding the previous period (August 2010 to November 2010).
