Climate variability refers to variations in the mean state and other statistics (such as standard deviations, the occurrence of extremes, etc.) of the climate on all temporal and spatial scales beyond that of individual weather events. The aim of the study is to gauge economic impact of climate variability on farms revenue in high vulnerable agro climatic zone of Tamil Nadu. Data were collected from TNAU meteorological department Coimbatore, about 180 samples were collected randomly to conduct this study. The results indicated that temperature (Kharif and summer) and rainfall (Kharif, Rabi and summer) had significantly influenced net revenue in irrigated farms and rain-fed farms. Temperature and precipitation were found to have significant impact in rain-fed farms and irrigated farms and the result suggests that irrigation is the efficient adaptation method.
