Eleventh International Conference on Climate Change: Impacts & Responses

Abstract

World is stirring towards urban transition-rapid and unplanned urbanization of cities and concomitant reduction in vegetation result in change in the urban energy balance. This alteration in energy balance has raised the temperature in urban center compared to non-urban areas, creating a phenomenon known as the ‘Urban Heat Island’ (UHI). The paper concerns about the mitigation policy of UHI in the urban centre with the utilization of blue-green infrastructure. The study focused on the “Surface Urban Heat Island” (SUHI) which is the effect generated by addition of heat energy in the urban center as well as change in urban climate. We classified SUHI zonation by exploring temperature difference between urban center and its surrounding regions, evaluating LST (Land surface temperature) with respect to blue-green network using remotely sensed data processed in ArcGIS. Further, the study quantified to mitigate the critical intensity of UHI through area-based approach such as providing urban park and water bodies proximity to the critical zone using urban planning guideline policy. The study helps in strengthening the existing policy related to change in urban climate.
