SUMMARY:

Human occupation has caused deforestation and environmental impacts, such as changes in water quality, biodiversity reduction, and pollution. The recovery of these degraded areas is essential to restore ecosystem integrity. In this context, the objective of this research was to survey deforested areas using the geospatial platform of Google Earth Engine between the years 2000 and 2020 in the municipality of Taquaritinga do Norte, Pernambuco, Brazil. Thus, a temporal analysis of land use and land cover, forest suppression, agricultural expansion, and urban expansion was conducted in the municipality of Taquaritinga do Norte. Maps were generated using Google Earth Engine and QGIS to understand landscape changes over the period from 2000 to 2020. The analysis revealed that anthropogenic activities intensified over time, resulting in modifications to natural landscapes and the replacement and exploitation of areas for various types of land use. This had negative impacts on the availability and quality of natural resources, such as soil fertility decline, erosion processes, biodiversity loss, and sedimentation of reservoirs and watercourses. When analyzing the images, an increase in non-vegetated areas was observed, mainly due to population growth in the municipality and the expansion of agriculture and livestock. There was a decrease in forest area over the period, mainly due to agricultural and livestock activities. The study also highlighted the importance of understanding population dynamics for spatiotemporal analyses. Forest suppression showed variations over the years, with peaks of recovery and loss of vegetation cover. The highest rate of forest suppression was recorded in 2009, while the highest recovery rate occurred in 2007. Agricultural expansion also increased during the period, resulting in a decrease in vegetated area and increased deforestation. The highest agricultural expansion was observed in 2009. Urban expansion was also identified, with a significant growth in the urban area over the years (188%). This contributed to increased deforestation in the region. To mitigate the intensive exploitation of natural resources and promote sustainable management, monitoring of land use and land cover is recommended. Additionally, techniques for the recovery of degraded areas, such as reforestation and ecological restoration, are suggested.
