Abstract
Global warming causing rapid rise in temperature is a major cause of concern. Several studies have highlighted the impact of vegetation on microclimatic regulation. The microclimate of a region regulates the thermal comfort level of dwellers. This study develops a framework to investigate whether the settlement near the age old ‘Acharya Jagadish Chandra Bose Indian Botanic Garden’ in Howrah district of West Bengal, India, covering an area of 270 acres, enjoys a microclimate which is affected by the wide range of vegetation of this garden and the river Ganga, by inferring radius of influence of cooling effect of the garden. This study is set out to also explore the changes that took place in local microclimate of the region near the garden after the super cyclone ‘Amphan’ struck the city between 16th to 21st May 2020. Amphan has caused a large scale destruction of trees in the botanical garden. The results of this analysis illustrates the effect on microclimate change, by establishing a correlation between LST (Land Surface Temperature) and NDVI (Normalised Difference Vegetation Index) of the garden, from satellite remote sensing observation, using pre and post event data. The significant observation of this study is that a large vegetation reserve in an urban setup, has an impact on the local microclimate and lowers the temperature in immediate neighbourhood. Thus maintenance of the existing garden is highly recommended to establish bioclimatic comfort in the urban settlement within the radius of influence of PCI of the garden.
