Impact of land-use dynamics on land surface temperature in Mumbai city, India: A geospatial approach

To assess and monitor the environmental dynamics on a regional or global scale, Land Surface Temperature (LST) has been estimated for South Mumbai, using Landsat data years 2000, 2010, 2015, 2020. The urban heat island (UHI) effect also assessed by analysing LST pattern in study area. normalized difference vegetation index (NDVI) analysis shows that UHI effects are less when cover is high. On contrary, built-up (NDBI) directly proportional to which indicates impact of human activities as well UHI. relationship between area ambient air temperature shown strong correlation with an increasing trend from 2000 reveals average Mumbai increased 27.1 32.7 °C last twenty years. ward-wise profile carried out address worst thermal discomfort zone associated population. suggests green space maintaining Mumbai. This provides baseline future studies like health, climate change, assessment ecological status, etc. environment.
