Abstract

This study examines the spatiotemporal dynamics of Urban Heat Island (UHI) effects within the framework of global urbanization, assessing the impact of Land Use Land Cover (LULC) alterations on Land Surface Temperature (LST), with a focus on Dhaka and Faridpur from 1999 to 2024. Landsat satellite imagery was employed to classify LULC classes and derive LST values, while indices such as NDVI, NDBI, and NDWI quantified the correlations between LULC changes and thermal patterns. The built-up areas of Dhaka expanded by 58.25 km2, whilst vegetation and water bodies diminished by 45.71 km2 and 15.16 km2, respectively, resulting in a 4.03 ℃ increase in mean LST. In contrast, Faridpur experienced gradual urbanization, with built-up regions expanding by 15.32 km2 and wetlands diminishing by 30.65 km2, resulting in a modest 1.13 ℃ increase in the mean LST. Regression analysis underscored the contribution of urbanization to the rise in LST, while vegetation and water bodies played a declining role in thermal regulation. Although constrained by the spatial resolution of medium-resolution data, this study provides important insights into urban thermal dynamics as part of a broader research initiative. These findings highlight the need for reforestation and water body restoration in Dhaka, alongside sustainable land-use policies in Faridpur, to mitigate UHI effects.
