Impact of land use and land cover on urban ecosystem service value in Chandigarh, India: a GIS-based analysis

Abstract

Abstract Assessing the effects of land use and land cover (LULC) on ecosystem service values (ESVs) is critical for public understanding and policymaking. This study evaluated the impacts of LULC dynamics on ESVs in Chandigarh city of India. The assessment of LULC changes was performed by analyzing the satellite imagery of the study area for the years 1990 and 2020 with different band combinations in ArcGIS (10.8 version software). In addition, we analyzed ecosystem services changes which were based on the LULC classes of the study area. Five LULC classes were identified in the present study area (Water bodies, forest and vegetation, built-up, agriculture and shrubland and open spaces). The results demonstrated (from 1990 to 2020) that the forest cover and agricultural areas decreased by 4.19% and 37.01%, respectively, whereas the built-up area substantially increased by 104.61%. Overall, ESV decreased by 2.54% from 1990 to 2020 due to rapid urbanization. The combination of LULC and ecosystem services valuation can increase our understanding of different issues of an urban ecosystem. Hence, we recommend the integration of LULC and ecosystem services valuation as a tool that could provide information to policymakers, urban planners and land managers for sustainable use in future.
