             abstract = "The Brazilian Amazon is covered not only by tropical dense forests 
                         but also by non-forest formations, mostly savanna (mosaics of 
                         grasslands, shrublands and forestlands) and periodically flooded 
                         campinas (sparse vegetation, usually over sandy soils) and 
                         campinaranas (low tree-dominated formation, in-between campinas 
                         and dense forest). The non-forest, natural formations occupy ~ 29 
                         million hectares in the Amazonia biome. Long-time, annual 
                         deforestation monitoring of the Brazilian Amazon has been 
                         conducted by the National Institute for Space Research (INPE) 
                         since 1988, more specifically, by the PRODES project, but only in 
                         forested areas. This study aims to estimate deforestation in 
                         non-forested areas of the Amazonia´s biome. Only polygons with 
                         size larger than 10,000 hectares were considered, that is, 66% (19 
                         million hectares) of total non-forested areas in the biome. The 
                         study was based on the RGB color composites of Landsat-8 OLI 
                         images (95 scenes; bands 4, 5 and 6), visually interpreted with 
                         the support of ArcGIS 9.3 software package. Two or more Landsat 
                         overpasses per scene were considered whenever cloud cover 
                         condition was high (more than 40%). Higher spatial resolution, 
                         RapidEye scenes as well as the images available in the Google 
                         Earth? software were also analyzed to support the Landsat image 
                         interpretation. Results showed that 5% (11,560 km2) of the study 
                         area were deforested in 2013. Mato Grosso was the state that 
                         presented the largest area of deforestation: 8,430 km2. Ongoing 
                         study is mapping polygons smaller than 10,000 hectares. Validation 
                         procedure to estimate the accuracy of the mapping results also 
                         will be considered.",
