Understanding the history of deforestation in the Amazon is essential to predict the future of this process under different scenarios and to identify effective measures for its control, avoiding the worst impacts. Controlling deforestation is crucial to preventing the impacts of forest loss today much of the deforestation process is beyond the government's control. This study aims to analyze the occurrence of deforestation in the last ten years, especially in the last year (2018-2019) between the cities of Boa vista and Brasília. The study area covers the 5 Km radius around the Boa Vista (RR) - Manaus (AM) - Brasília (DF) airway / airliner. For the analysis of deforestation the PRODES and MapBiomas database was used for that year from 2008 to 2019 and for this year from 2008 to 2018. Thus it was possible to compare the results of the deforestation of PRODES and MapBiomas, in each state and year from area and percentage of deforestation. It was noticed through the deforestation data for the period from 2008 to 2019 that the state with the largest deforested area was Pará and in second place Mato Grosso. This is due both to the fact that the airway has the largest extensions to these two states and because they are increasing activities related to agribusiness, mainly soy and livestock in the regions studied. In addition, there was a significant decrease in deforestation in the period from 2008 to 2017 in the study region, but as of 2018 this deforestation started to grow again. Thus, the knowledge of tools such as those used in the study is essential for planning public policies that are more appropriate and directed to the Amazon.
