ABSTRACT

This study investigates the urban heat island (UHI) effect in Hyderabad, Telangana, focusing on the Greater Hyderabad Municipal Corporation (GHMC) area, which spans 650 square kilometers. The analysis integrates land use and land cover (LULC) changes and future climate projections, estimating annual average temperature and precipitation trends up to 2100. Utilizing data from USGS Landsat-8, SRTM-DEM, and IMD, various thematic maps, including elevation (ranging from 456 to 637 meters) and natural infrared. LULC data from 1985, 1995, 2005, and 2023 were analyzed to identify significant changes over time. Moreover, other directories like NDBI, NDVI, and NDWI originated from Landsat-8 information collected from different terms in 2021, 2022, and 2023.The results indicated significant trends in climatic impact caused due to urbanization, which outlined the increase in surface temperatures and intensified UHI effects. UHI in the GHMC area is categorized into two groups, with high values of 329.75 and low values of 72.04. Rainfall is categorized into high (251-1500 mm), medium (26-250 mm), and low (0-25 mm). Additionally, the analysis considered different Shared Socioeconomic Pathways (SSPs) – SSP1 2.6, SSP2 4.5, SSP3 7.0, and SSP5 8.5 to project temperature, precipitation and humidity trends until 2100. The findings contribute to understanding climate impacts, guiding sustainable urban development, and enhancing climate resilience in the GHMC region.

Keywords: Urban Heat Island (UHI), Greater Hyderabad Municipal Corporation (GHMC), Land Use and Land Cover (LULC), Landsat-8, Temperature, Precipitation, and Land Surface Temperature (LST).
