This study examines the environmental impact of waste accumulation and land use changes surrounding Delhi’s major landfill sites, including Okhla, Bhalswa, and Ghazipur, utilizing geospatial techniques. The research focuses on analysing spatio-temporal variations in Land Surface Temperature (LST) and Land Use/Land Cover (LULC) patterns over the years 2016, 2020, and 2024. LST maps were generated for both summer (April–June) and winter (November–December) seasons using Landsat-8 imagery, highlighting seasonal thermal anomalies across the landfill areas. Additionally, Sentinel-2 satellite data was used to classify LULC within a 3 km buffer zone around the landfills, capturing changes in vegetation, built-up areas, agriculture, barren land, and water. The findings indicate consistent changes in surface temperature, especially during the summer months, as well as a noticeable expansion of built-up areas and a reduction in vegetation around the landfills over time. The study underscores the significance of remote sensing and GIS in monitoring urban environmental changes and offers valuable insights for sustainable waste management and urban planning in rapidly urbanizing regions like Delhi.
