Multitemporal deforestation in the Caatinga biome in the municipality of Delmiro Gouveia, Alagoas, Brazil
The Caatinga biome predominates in much of the northeastern region of the country, comprising about 48% of the state of Alagoas, extending through the municipality of Delmiro Gouveia. Caatinga is currently undergoing a process of suppression due to agricultural expansion, fires in the area, logging...

| Sumario: | The Caatinga biome predominates in much of the northeastern region of the country, comprising about 48% of the state of Alagoas, extending through the municipality of Delmiro Gouveia. Caatinga is currently undergoing a process of suppression due to agricultural expansion, fires in the area, logging for commercial purposes and natural phenomena. Thus, the present work aimed to analyze in a multitemporal way the changes in the Caatinga vegetation over 33 years. For this research, we used the Qgis software and data from the Mapbiomas 4 collection in order to understand Caatinga dynamics. From the results, it was found that there were changes over the analyzed time, indicating a deforestation of 71.52 km², which is equivalent to 27% of the area. However, we observe a regeneration process after a long period of deforestation and desertification of the biome. For the area to accelerate the recovery process, further studies of remote sensing are necessary, together with new analyzes of the landsat satellite, as well as more inspection by the responsible agencies. |
