Abstract
The urban areas are over-expanding to their permissible spatial limits to accommodate the increasing population. This has also brought about an increase in the allied sectors of grey infrastructure along with the massive modifications in the current land uses. The rapid conversion of the green and agricultural land into built-up areas is an observation due to these changes. The consequent effects of such changes and haphazard growth have led to changes in the climatic conditions, such as an increase in the urban temperature levels, unforeseen weather switches, and unpredictable seasonal changes, etc. The paper attempts to study the changing trends in the land use-land cover (LULC) sectors and its relative inter-relationship with the surface temperatures, for the Indore city of Madhya Pradesh (M.P.), India. The remote sensing technology is used to generate the land cover and the thermal maps and a comparative decadal analysis is done for the years 1996 and 2019. An approximate 3 to 5°C increase in the surface temperature is observed from the analysis and the increase in the human-generated anthropogenic activities prevalent in those specific areas could be concluded as one of the major reasons of the expansion in the city’s heat island effect.
