Análise temporal do índice de áreas desmatadas na mesorregião do sudeste paraense

The rates of deforested areas increase as the population growth due to the expansion of the roads, increased urban, agricultural growth, etc. The mesoregion of southeastern of Pará is located in the region called arc of deforestation. In this mesoregion has a several national projects, generating profits for the state and the country, but is also considered problematic due to the high rate of deforestation that it has. Considering these factors, this study has an intention to accomplish a temporal analysis of deforested areas in this mesoregion in order to verify the behavior of deforestation rates during the years of 2004 to 2015 and still analyze the accumulated deforestation between the years 2004 - 2009 and 2010 - 2015. In result, was observed that in the period of this study the deforestation has decreased. The year of 2004 has a 560.831 hectares of deforested area, the highest rate among the years; while the year of 2015 has a 59.654 hectares of deforested area, lowest deforestation rate. Analyzing the accumulated deforestation, between the period 2004 - 2009, was obtained 2.160.059 hectares of deforested area and between 2010 - 2015 the total deforested area was 480.330 hectares. In general, occurred a decrease of 77.76 % of deforestation from the first to the second study period, resulting from government projects and incentives to combat deforestation in the Amazon.
