Effect of LULC Changes on Land Surface Temperature
The rapid urbanization of cities has led to significant human-induced alterations to the environment, characterized by the replacement of natural land cover with man-made structures such as concrete, bricks, asphalt, and metal. This transformation disrupts the natural processes of evapotranspiration, resulting in reduced cooling effects and increased heat storage within urban areas. This study involves the Land Surface Temperature (LST) variation over different classes of Land Use Land Cover (LULC) and the effect of change in LULC over the past two decades in and around Hyderabad City, Telangana, India. This is a Tier-1 Indian city experiencing notable LULC changes from the past two decades due to rapid Urbanization. This study examines how urbanization has affected the surface temperatures from the past twenty years, using Landsat 7 and Landsat 8. Spectral indices such a LULC, Radiance, Brightness temperatures and Land Surface Emissivity (LSE) have been generated and utilized for the generation of LST. A substantial change of vegetation increased by 28.92% from 2012 to 2022 period. And also, an urban area increasing by 108.8% but waterbodies have decreasing and increasing patterns in the period of 2012–2022. It is advised to implement efficient urban planning and design solutions to lessen the negative consequences of LST changes caused by LULC. Green space inclusion, vegetation restoration, cool pavement and roofing techniques, and sustainable urban design techniques are among those to be employed in order to reduce the effect of these temperature changes.
