Spatiotemporal Evaluation of Land Use Dynamics and Their Thermal Impacts Using LST, NDVI and NDBI in Nagpur District, India (2005-2025)

Year: 2026
Type: conference-paper
Abstract: The paper analyses effect of the Land Use/Land Cover (LU/LC), Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI) over the Land Surface Temperature (LST) in the Nagpur District of Maharashtra using Landsat satellite imagery for year 2005, 2015 and 2025. The classification accuracy improved from 81%$(\mathrm{K}=0.75)$in 2005 to 94%$(\mathrm{K}=0.92)$in 2025. From 2005 to 2015, agriculture grew by 198.33% (+2272.36 km2), replacing vegetation (-48.35%) and Built-up areas (- 41.30%). By 2025, built-up area increased by$\mathbf{9 7. 8 0 \%}$, replacing large agricultural areas and open land. NDVI values continuously declined, which means vegetation stress has increased. While NDBI values rose in the urban regions, it reflects impervious surfaces have increased quickly. The mean LST increased from 2.71° C (water bodies) to 13.23° C (open land), In 2015, it rose to 24° to 26° C. In 2025, reaching 30°C (water), 42°C (vegetation), 46°C (Built-up) and 48° C (agriculture) which was recorded as highest. While the water bodies continuously observed as coolest surfaces. Correlation analysis showed strong positive relationships between LST and LU Index$(\mathbf{r}=\mathbf{0. 9 4}$to 0.97) and between LST and NDBI$(\mathbf{r}=\mathbf{0. 8 5}$to 0.90). While NDVI with LST demonstrate strong negative correlation$(\mathrm{r}=-0.92$to 0.96). This research confirms that vegetation is the critical cooling factor and highlights the increasing impact of urban sprawl over Urban Heat Island (UHI). The study suggests a holistic framework to the policy makers and urban planner to make a sustainable community in central India.
