             abstract = "In the semiarid region, there are factors that cause degradation 
                         of the environment: climatic variations, soil degradation with 
                         overgrazing, irregular management practices and loss of vegetation 
                         cover. In the Brazilian Northeast, where the Caatinga biome is 
                         present, these pressure factors act intensely on the ecosystems. 
                         Another factor of concern is the insertion of vegetative species, 
                         with characteristics of monodominance in areas of Caatinga. The 
                         rapid expansion of these species is characterized as biological 
                         invasion, endangering the biodiversity of the Caatinga biome. This 
                         paper aimed to map the occurrence areas of Algarobas (Prosopis 
                         juliflora (SW) DC), at the Polo de Jeremoabo-BA. For this, the 
                         mapping was performed through the Spectral Angle Mapper (SAM) 
                         classification algorithm, using the spectral-temporal curves of 
                         the Enhanced Vegetation Index (EVI), of the sensor Moderate 
                         Resolution Imaging Spectroradiometer (MODIS). These data compose a 
                         time series from the years 2001 to 2012, totaling 276 images. The 
                         algaroba plant was introduced in the northeastern semiarid region 
                         as an alternative, due to its fodder potential for animals, 
                         firewood, and human food, however studies have shown some concern, 
                         due to its proliferation capacity, causing great economic or even 
                         biological losses, by the extinction of the native vegetation. The 
                         information extracted allowed to quantify the mapped areas, 
                         totaling in about 45,184 Km2. The areas of algaroba were mostly 
                         found at altitudes ranging from 244 to 430 m. The statistical 
                         analysis showed an overall accuracy of 78%, and the Kappa Index 
                         was 0.47.",
