摘要

The current growth in urban centers particularly in fast-growing regions tends to trigger unsustainable land-use shifts that have an unequal impact on the vulnerable groups, particularly the people in informal settlements. This Research study examine both spatial and temporal variations in land use land cover alterations together with their effects on slum development within five municipalities namely; Contai, Haldia, Tamralipta or Tamluk, Panskura and Egra Municipality of East Midnapore district in West Bengal, India. The main aims of the study are to examine LULC changes during the last 20 years (2001–2021), and assess the associated changes in Land Surface Temperature (LST) and Ecosystem Service Value (ESV). Rapid urban growth since 2001 caused developments toward built-up establishments that required exchange of agricultural land, vegetation cover and wetlands which transformed the landscape fundamentally. To measure LULC transformations this research analyzes satellite imagery for the year of 2001, 2011 and 2021 by applying supervised classification and also measure land surface temperature (LST) and ecosystem service value (ESV). In this study a multi-ring buffer technique (0–300 m) is used, which produced results like environmental exposure in terms of temperature, changing nature of LULC and ESV of slum settlements in Purba Medinipur district. The current study shows that there has been a significant encroachment of the urban space on agricultural lands, vegetated surfaces, and wetland and that this has led to significant increases in LST (up to 10 °C) and a significant decrease in ESVs, particularly in Haldia, Contai, and Tamralipta. These changes increase environmental hazards to informal settlements, especially exposure to heat-stress and a reduction in ecological resilience. These findings point to the urgent need to have environmentally sensitive urban planning that balances developmental goals with conservation of the environment. As a result, the combination of wetland protection, sustainably designed land-use zoning, and overall infrastructure improvement in slum areas becomes essential to the development of climate-resistant and equal urban environments. In general, the results can be of paramount value to policymakers, urban planners, and local authorities that aim to manage urbanization without compromising ecosystem services and disadvantaged groups.
