Item Análisis multitemporal del cambio de cobertura vegetal debido a la explotación de carbón a cielo abierto en la mina El Cerrejón, ubicada en el departamento de La Guajira, Colombia, durante el período comprendido entre 1986 y 2023.(Universidad Santiago de Cali, 2023-09-13) Arango Cifuentes, Andres Mauricio; Orozco Ordoñez, IvánThe open-pit coal mining in the La Guajira department has experienced significant growth in the last four decades, raising questions about the extent and consequences of vegetation loss in the region. The aim of this study is to conduct a multitemporal analysis of changes in vegetation cover in the El Cerrejón coal mines and surrounding areas from 1985 to 2023. By utilizing geospatial analysis techniques in the open-source software QGIS and satellite imagery from Landsat and Sentinel remote sensors, subsequently processed with the Semi-Automatic Classification Plugin (SCP), graphical outputs were obtained to quantify and evaluate historical changes in the study area, as well as understand the spatial and temporal behaviors of observed changes. This multitemporal analysis provides a deeper insight into the magnitude and dynamics of changes in vegetation cover due to mining exploitation. The results of this analysis are expected to contribute to a better understanding of the environmental impacts of extractive activities in the La Guajira department, providing essential information for environmental management decision-making. Likewise, it is anticipated that this study will serve as a scientific basis for the implementation of mitigation and ecological restoration strategies in areas affected by vegetation loss.
