Lençóis Maranhenses PARNA and APA of the Mouth of the Preguiças River: Spatial-temporal Analysis of the Dynamics of Land Use and COVER (1985 - 2022)

Abstract

This study analyzed the spatiotemporal dynamics of land use and occupation in the Lençóis Maranhenses National Park and Foz do Rio das Preguiças Environmental Protection Area Conservation Units. The free QGIS software and classified data from the MapBiomas platform were used for the period 1985 to 2022. The results revealed a 3.18% reduction in natural areas, an increase in non-vegetated areas and areas used for agricultural purposes, as well as a decrease in water bodies and non-forested natural formations. Eighty-eight species were identified as declining in population: 47 vulnerable, 27 endangered, and 19 critically endangered. This evidence reinforces the urgency of interdisciplinary studies to understand and mitigate the impacts of anthropization and ensure the preservation of biodiversity and the biosphere.
