             abstract = "Although the Brazilian Savannah shows large flora richness, it has 
                         been impacted by anthropogenic factors. The basin of the 
                         Paran{\~a} river is geographically located within the Brazilian 
                         Savannah region and Tocantins basin, which also shows a unique 
                         natural biological richness that makes this area very important 
                         for environmental conservation. This study conducted a 
                         multi-temporal analysis of the land use and land cover change in 
                         the Arraias municipality, State of Tocantins, located at the basin 
                         of the Paran{\~a} river, in 2000, 2005, and 2010, based on remote 
                         sensing imagery and geoprocessing tools. Based on it, unsupervised 
                         classification (K-Means, a built in technique available in ENVI 
                         4.6®) to map land use and land cover change over the study area. 
                         The ENVI 4.6® built in technique K-means was used. The land use 
                         and land cover classes adopted were: Deforestation, urban area, 
                         rock exposures, water bodies, open and dense vegetation). 
                         Furthermore, it was assessed impacts on natural vegetation (open 
                         and dense vegetation types) using Normalized Difference Vegetation 
                         Index (NDVI). These study results showed that the deforestation 
                         did not increase substantially in the study area between 2000 and 
                         2010. However, it has been observed that the remaining natural 
                         vegetation is located in inaccessible, hilly, and rocky areas. The 
                         vegetation index results indicated that degradation process did 
                         not change either for the remaining natural vegetation. Finally, 
                         the results of this study may help to improving the development 
                         and conservation plans for the study region.",
