In November 2012, half part (50%) of the Legal Amazon forest area was covered by clouds, mainly the states of Acre and Mato Grosso with, respectively, 81% and 77% of clouds covering. This compromised the deforestation and the forest degradation detection for this month through the MODIS images used by SAD.
In these conditions, only 55 square km of deforestation were detected in November 2012 in the Legal Amazon. This represented a 258% increase compared to November 2011 when deforestation summed 16 square kilometers for a cloud covering of 71% of the whole Amazon forest area. This clouds covering difference may compromise the comparison between the months of November 2012 and 2011.
Accumulated deforestation from August 2012 to November 2012 summed 1.206 square kilometers up. A 129% increase was observed compared to the former period [August 2011 to November 2011], when deforestation summed 527 square kilometers.
In November 2012, most part of deforestation (42%) occurred in the State of Pará, and then in Rondônia (25%) and Amazonas (24%). The remaining occurred in Roraima (4%) and Tocantins (1%).
Degraded forests in Legal Amazon summed 100 square km in November 2012. Compared to November 2011, when the forest degradation summed 40 square kilometers, an increase of 154% was observed.
Accumulated forest degradation in the period (August 2012 to November 2012) summed 711 square kilometers. Compared to the former period (August 2012 to November 2011), when forest degradation summed 1285 square kilometers, a 45% reduction was noticed.
In November 2012, SAD detected a deforestation involving 1.5 million tons of equivalent CO2. For the accumulation of the period (from August 2012 to November 2012) the compromised equivalent CO2 emissions summed 60 million tons representing a 32% reduction compared to the former period (August 2011 to November 2011).
