Abstract

The present research deals with an in-depth analysis of COVID-19 risk in the state of Kerala using the integrated approach of the hazard and vulnerability in a GIS platform. Considering the probable causative factors of this disease, several geo-environmental indicators are analyzed through various statistical and geospatial techniques. Lorenz curve indicates an uneven distribution of COVID-19 instances in Kerala. Hazard analysis is formulated based on the proximity to hotspots and LULC followed by vulnerability analysis using an integrated analytical hierarchy process (AHP). Risk analysis reveals that COVID-19 infection poses a very serious threat to around 2.39% of Kerala's total land area, with high, medium and low risks of 38, 44 and 14% respectively. The outcomes of this research will be a first-hand tool for policymakers to safeguard the population in high-risk potential zones from the future spread of infectious disease.
