Landscapes in transformation: multitemporal analysis of the Cerrado's vegetation cover around the Corumbá IV lake using remote sensing

Abstract

The Cerrado plays a fundamental role in water resource conservation, fostering increased biodiversity within its area. To preserve these natural resources, it's essential to conduct studies that can spatially demonstrate the evolution and distribution of vegetation. This article focuses on identifying changes in vegetation cover near Lake Corumbá IV, caused by the accelerated urbanization of this landscape and monitored using satellite imagery and the NDVI (Normalized Difference Vegetation Index). The study area encompassed 1,200 meters from each margin of Lake Corumbá IV, due to the formation of new condominiums and the presence of serious challenges for environmental conservation and management. Utilizing a time series of satellite images (Landsat 5 for 2002, 2006 and 2011; and Landsat 8 for 2016 and 2022), the results clearly demonstrate the progressive fragmentation and reduction of Cerrado areas. This continuous degradation in the studied landscape points to the urgency of conservation and management actions to mitigate impacts and protect the biome.
