| Sumario: | The insertion of agribusiness in the micro-region of Chapadinha (MA), from the end of the 20th century to the present day, (re) configured the region’s agrarian space. Considering that the soybean production in the municipality of Brejo was the highest among the municipalities that make up the microregion in the period between 2003 and 2010, this work points out the transformations that occurred in the municipality's vegetation cover through the calculation of the Normalized Difference Vegetation Index (NDVI). In order to do this, satellite images from Landsat5 were used to calculate the NDVI and then analyze agricultural expansion. With the result of the investigation, it was laid out how the agricultural expansion process and, consequently, the deforestation of native vegetation occurred. |
