Assessment of Vulnerability to Climate Variability

The IPCC Third Assessment Report defined vulnerability as “The degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change, including climate variability and extremes”. There were so many studies with regard to the vulnerability of climate variability. Vulnerability indices are multivariate in nature and principal component analysis (PCA) is used to assess it. The study selected seasonal (rice), annual (banana) and perennial crops (coconut and mango). The crops like rice, banana and coconut were affected due to climate variability. It was mainly due to high temperature and low rainfall in the study period. In the case of mango production, it was not so affected because the nature of climate variability in 2016 favoured mango production.
