Rapid urban growth within short period of time creates havoc changes in land use land cover (LULC) all over the world especially in developing countries. Numerous Indian cities are facing such type of problems mainly due to the unplanned and haphazard urban growth. The present study emphasizes on the land use land cover changes using satellite imageries from 1991 to 2021 at ten years interval and its impacts on land surface temperature (LST) in Rajpur-Sonarpur Municipal area located in the district of South 24 Parganas, West Bengal. It was found that over the last 30 years, positive changes occurred in case of built-up area (9.26% to 45.96%) and open space (1.24% to 23.05%) while negative changes found in vegetation coverage (40.99% to 19.32%), water bodies (4.34% to 2.03%) and agricultural land (44.16% to 9.63%) in terms of total geographical area. On the time being there is an increasing tendency of construction sites and built-up areas at the cost of vegetation coverage as well as the water bodies and agricultural lands which in turn increase the land surface temperature as a continuous process. An average 3 degree Celsius (o C) temperature increased during the study period. So, to arrest the rising temperature and minimize the ill effects of such changes immediate thinking of new urbanism should be adopted and implemented.
