Martins, H., Fonseca, A., Souza Jr., C., Sales, M., & Veríssimo, A. 2013. Forest Transparency for the Brazilian Amazon (March 2013) (p. 13). Belém.
In March 2013, most part of forest region in Brazilian Amazon (60%) was covered by clouds, which compromised the forest degradation and deforestation detection via MODIS images used by SAD. Under these conditions, it was possible to detect only 80 square kilometers of deforestation in Brazilian Amazon. It represented an increase of 50% in comparison to March 2012, when the deforestation totaled 53 square kilometers and the clouds coverage totaled 74%.
The accumulated deforestation for the period from August 2012 to March 2013 totaled 1.430 square kilometers. There was an increase of 88% in comparison to the previous year (August 2011 to March 2012) when the deforestation totaled 760 square kilometers.
In March 2013, most part (56%) occurred in Mato Grosso, followed by Rondônia (28%), Pará (9%), Roraima (3%), Acre (2%) and Amazonas (2%).
The deforested area in Brazilian Amazon totaled only 9 square kilometers in March 2013. In comparison to March 2012, when the deforestation totaled 40 square kilometers, there was a reduction of 90%.
The forest degradation for the period (August 2012 to March 2013) reached 1.100 square kilometers. In relation to the previous year (August 2011 to March 2012), when the degradation totaled 1,568 square kilometers, there was a reduction of 30%.
In March 2013, the deforestation detected by SAD compromised 1,5 million tons of equivalent CO2. For the accumulated period (August 2012 to March 2013) the emissions of equivalent CO2 compromised by the deforestation totaled 79 million tons, which represents an increase of 38% in comparison to the previous year (August 2011 to March 2012).
