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.",
