Over the years, land use and occupation patterns in the municipalities located within the Paraná III Basin have been modified as a result of various interactions between human activities and the natural environment. Acquiring knowledge about the quantitative and qualitative distribution of land use and occupation is essential for economic, social, and environmental development. Remote Sensing has become increasingly important for global data acquisition and distribution, particularly environmental data. This information facilitates and contributes to the monitoring and preservation of natural resources, playing a key role in developing solutions to mitigate human impacts. This study aimed to perform a multitemporal analysis of land use and cover in Itaipulândia, located in western Paraná, using freely available LANDSAT-5, LANDSAT-8, and LANDSAT-9 imagery from the United States Geological Survey (USGS) for the years 2000, 2005, 2010, 2015, 2020, and 2024. The supervised classification method (key method) was employed, with training areas selected for each class using the Bhattacharyya algorithm. Classification was performed using SPRING software, which categorizes the percentage of area for each training region, with final outputs generated as print layout maps in SCARTA. Results showed that water bodies remained stable throughout the period, ranging between 41.38% (2000) and 41.58% (2024) of the total area. Agricultural areas (crops + bare soil) varied around a mean of 39.2%, with a peak in bare soil at 28.28% in 2005. Forested areas increased from 15.12% in 2000 to 20.03% in 2024, indicating the effectiveness of environmental recovery programs in the region.
