National Institute for Space Research presented on Tuesday, during the Climate Change Brazilian Panel, in Brasilia, the first results about greenhouse gas emission related to the Amazon deforestation.
INPE estimated the amount of carbon dioxide discharged in the atmosphere by the deforestation to advise and properly subside both deforestation reduction policies and emissions. The study introduce annual estimation for all Amazon up to 2008 and in this evaluation, considered the data of its Prodes system, that monitors by satellite and quantifies the deforested areas in Amazon.
According to this study, from 1999-2008 the Amazon emission registered about 700-800 MtonCO2 (millions of tons of carbon) annually. Though, having a decrease in the deforestation rate in the recent years, 2007-2008 the emission average also got lower to 500-550 MtonCO2/year.
The specialists studied the emission in each of nine States of Amazon and the results reflect the social economic and regional biophysical differences. For instance, Mato Grosso from 1989-1998, contributed to 36% of regional deforestation rates, although only 29% of the clear emission in the same period is from the State. The differences between the deforestation percentage as well as the emission occur by the biomass variation in the Amazon state.
According to INPE’s researchers, these results show how important it is to consider the regional differences, the deforestation process dynamics and it’s unlike components, for both estimating the emission and to guiding governmental actions with the purpose of getting its reduction.
