Abstract
Urban Heat Islands (UHI) are a growing concern in rapidly urbanizing regions, leading
to significant ecological and public health challenges. This study investigates the spatiotemporal dynamics of UHI intensity in Mbombela City, Mpumalanga Province, South
Africa, from 2008 to 2023. Using Landsat satellite imagery and geospatial analysis
techniques, the research quantifies changes in land cover and their impact on Land
Surface Temperature (LST) and UHI intensity. The results show that built-up areas
increased by 86.67% over the study period, while vegetation cover decreased by
22.22%. Mean LST rose from 28.3°C in 2008 to 30.1°C in 2023, indicating a significant
intensification of the UHI effect. Statistical analyses reveal strong correlations between
urbanization metrics and UHI intensity, highlighting the role of human activities in
exacerbating this phenomenon. This research contributes valuable insights for urban
planning and climate adaptation strategies, particularly in secondary cities like
Mbombela, where rapid development is creating new environmental challenges. The
findings underscore the need for green infrastructure and nature-based solutions to
mitigate the negative impacts of urbanization.
