Abstract

Index is an indicator or measurement of something. The word ‘index’ is a statistical measure of change in a representative set of individual data points. These numbers can come from various of sources, prices, productivity and employment. The term index has various meanings. For our purpose, it is a numerical scale computed from a collection of indicators chosen by the researcher for each district and used to compare them to one another or to some reference point. Climate change is a contentious issue right now. Vulnerability is an exposure of individuals or collective groups to livelihood stress as a result of the impacts of such environmental change. Objective of this research is to develop the vulnerability index to climate change. The study implemented the vulnerability method according to Iyengar and Sudarshan to evaluate vulnerability for 04 various components. The various sectors according to the different indicators are used to progress a hierarchy of vulnerability classifi

Conclusion

Vulnerability differs significantly across regions, it is recognised that “even within regions, impacts, adaptive capacity and vulnerability will vary and the Tamil Nadu state of cuddalore district is no exemption to this. District wise results reveal the primary contributor for the overall vulnerability of the climate change is agricultural sector. Because the agricultural sector has the largest impact, investments in research capacity adaptation are needed, notably in the creation of climate proof crops (drought resistant and heat tolerance types) that can withstand a broad variety of climatic circumstances. Vulnerability index was developed by using Iyenger and Sudarshan’s method and it led to find most vulnerable area among these districts.
