%K Amazon, fires, hot pixels, land-use change.
%X The principal objective of this study was to compare the hot pixels detected by the GOES-10, GOES-12, NOAA-12, NOAA-15, AQUA and TERRA satellites in municipalities (counties) in southwestern Amazonas State (Apuí, Boca do Acre, Canutama, Humaitá, Lábrea, Manicoré and Novo Aripuanã) and in the "MAP" area (Madre de Dios-Acre-Pando) during the period from 2003 to 2008. During the study period between 50 and 80% of the hot pixels detected by the satellites in the state of Amazonas occurred in the southwestern portion of the state, especially in the municipalities of Apuí, Boca do Acre and Lábrea. The highest number of hot pixels in the study area occurred in 2005, when a severe and prolonged drought provoked fire events contributing to the occurrence of forest fires and accidental fires in cleared areas and throughout southwestern Amazonia. In 2005 Acre was the burning champion, followed by southwestern Amazonas, Pando and Madre de Dios. In 2003, 2004, 2006, 2007 and 2008 the location with the highest number of hot pixels was the southwestern portion of Amazonas. This indicates that the use of fire in the area is intensifying and suggests that changes in land use and land cover are transforming the landscape with consequences for regional and global climate change. Understanding the evolution and the behavior of fire events in southwestern Amazonia is critical and requires the continual attention of the regional and national societies of the three countries that share the area.
