Title : SPATIAL -TEMPORAL CHANGE IN LAND USE LAND COVER AND ITS IMPACT ON SURFACE TEMPERATURE: AN ANALYTICAL STUDY OF BATHINDA CITY, PUNJAB
1Gurvinder Singh, 1Ajay Roy

Abstract :

The current study focuses on spatial and temporal land surface temperature changes as well as "Land use / land cover changes in Bathinda, Punjab." Land use changes are highly active in nature and should be evaluated on a regular basis for long-term development. This paper examines surface temperature changes in relation to changes in land use and land cover in Bathinda, Punjab, over a 32-year period. This study is primarily based on multi-temporal (1990, 1999, 2010, 2022) satellite images (Landsat8 and Landsat5). Land surface temperature is an important indicator in the study of the earth's environment. Land use/cover changes have a significant impact on the environment. Supervised classification was used to analyse land use for various time periods. Using Land sat satellite images, various LULC classes, such as agriculture, open land, vegetation, built-up areas, and water bodies, were demarcated and mapped. Over a 32-year period, large-scale changes in land use/land cover were discovered in Bathinda city. These changes could be attributed to rapid urbanisation and other forms of development. Bathinda's built-up and vacant areas have grown during this time period. In comparison to other land cover characteristics, all land cover categories' land surface temperature has risen during this time period. The temperature has raised the most in the built-up and open areas. Temperatures have raised more in areas classified as built-up urban, as opposed to agriculture, open land, and vegetation. Agricultural land has decreased as most agricultural fields have been converted into built-up areas and vacant land (essentially acquired for construction and subsequently such vacant areas have also been converted into built up area). It is therefore critical that the study be very visible because extensive changes in land use and land cover change have an impact on the socio-economic scenario of the area under study and are required to provide the amenities that the transformed land deserves for overall development of the area.
