USO DO NDVI PARA ANALISE MULTITEMPORAL DA UNIDADE DE CONSERVAÇÃO RPPN PATA DA ONÇA

Abstract

This study addresses the environmental conservation of the Private Natural Heritage Reserve (RPPN) Pata da Onça, located on the Santa Sophia Farm in the Pantanal region of Mato Grosso do Sul, using a multitemporal approach to analyze vegetation cover. Through the Normalized Difference Vegetation Index (NDVI), satellite images from 2005, 2020, and 2024 were evaluated to identify changes in vegetation and soil within the reserve and its surroundings. The results revealed a significant reduction in arboreal and herbaceous vegetation, accompanied by an expressive increase in exposed soil, indicating a continuous process of environmental degradation. The research highlights the importance of geotechnological tools, such as Geographic Information Systems (GIS) and remote sensing (RS), for monitoring protected areas, enabling detailed and cost-effective analyses. The decline in vegetation cover over the analyzed period suggests the need for more effective public policies and management actions to ensure environmental conservation and the recovery of native vegetation. The RPPN Pata da Onça, despite its strategic role in preserving the Pantanal ecosystem, faces challenges related to anthropogenic pressure, such as agricultural expansion, management failures, and climatic impacts. This study contributes to understanding conservation dynamics in Protected Areas and emphasizes the urgency of initiatives that promote sustainability and ecological balance in the region.
