The escalating trend of global urbanization, particularly pronounced in the burgeoning urban areas of Pakistan, necessitates a meticulous examination of Land Use/Land Cover (LULC) changes and their extensive environmental repercussions. Understanding these transformations is crucial for informed decision-making in evolving ecological dynamics. This research utilizes Geographic Information Systems (GIS), Remote Sensing (RS), and statistical analyses to investigate LULC thoroughly changes in Okara District, Pakistan, from 1991 to 2023. Despite its considerable socio-economic significance, Okara District has remained relatively understudied, making this research a crucial contribution to understanding its evolving landscape. Key indicators include the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI), correlated with Land Surface Temperature (LST). Findings include a 22.6% decline in vegetation cover (415.1 km
