An Approach for Measuring Vulnerability to Risk and Climate Change—A Case Study of Maharashtra State

The quantification of vulnerability is required to understand the impacts of an extreme event on a region, with the vulnerability being relative and specific to the particular region as access to resources among the population differs. To capture this, Theil Index is used which when used as a measure of redundancy can act as a measure of lack of diversity and inequality. The vulnerability index designed with the Theil index for the districts in the Maharashtra state is relative to that district and it illustrates the inequality and disparities in the accessibility of resources only for that particular district. It is formed based on the parameters which act as the proxies for exposure and sensitivity which are intrinsically related to the vulnerability of the region. These parameters provide the notion to act up in case of extreme events or disasters arising due to climate change or undue risks.
