             abstract = "This study carried out an analysis of the changes in land use and 
                         occupation of the Ondas River Basin, State of Bahia, through the 
                         use of Geographic Information Systems (GIS) and Remote Sensing 
                         techniques. To perform the analysis of changes in land use and 
                         occupation of the Ondas River Basin, supervised classification of 
                         satellite images of two different periods (1975 and 2015) was 
                         carried out. In the supervised classification the Support Vector 
                         Machine classifier (SVM) and images of the Landsat 1 (scenario of 
                         1975) and Landsat 8 (scenario of 2015) were used. In the scenario 
                         of 1975 there was the predominance of the native vegetation with 
                         the registration of some burned areas. Already in the scenario of 
                         2015 a significant reduction of the native vegetation area was 
                         identified due to the agricultural expansion in the region, which 
                         already occupies 45% of the area of the basin. Agriculture 
                         predominates in the western region of the basin. This is mainly 
                         because it is a flat area with high rainfall levels, which allows 
                         the development of crops such as soybean, corn and cotton, which 
                         predominate in this region. The SVM classifier presented a good 
                         result in the classification of the use and soil cover of the 
                         Ondas River Basin, making it possible to verify that the basin 
                         underwent an intense modification in its use and occupation of the 
                         soil, with the expansion of agricultural areas to the detriment of 
                         native vegetation areas, which can cause numerous impacts and 
                         imbalances in the environment.",
