Abstract: Amidst the rapid urban expansion transforming cities worldwide this study explores three decades (1990-2021) of urban expansion in Model Town Lahore revealing how rapid development has affected Land Surface Temperature (LST) and green spaces in this historically unique Model town. Utilizing Landsat 5 TM and Landsat 8 OLI satellite imagery we calculated the Normalized Difference Built-up Index (NDBI) and applied an index-based classification technique to quantify changes in built-up and non-built-up land. The results reveal a substantial increase in built-up area from 2.667 km² to 4.969 km² in Model Town, and from 455.45 km² to 807.40 km² in Lahore. Concurrently, the mean LST rose from 27.49℃ to 30.62℃ in Model Town, and from 25.72℃ to 29.17℃ in Lahore indicating a steady increase over the study period. Additionally, vegetative cover decreased significantly, with a 13.82% reduction in Lahore and a 128.47% reduction in Model Town. These findings underscore the critical need for sustainable urban planning to manage the adverse effects of rapid urbanization on temperature and green spaces.
