Karnataka is the second largest drought prone area in the country next only to Rajasthan and water availability is one of the major concerns in the state. The present study was conducted in eight districts based on the composite climate vulnerability index. Climatic data on rainfall, relative humidity, wind speed, minimum temperature, maximum temperature and average temperature from 1981 to 2018 were collected. The results revealed that in least vulnerable districts (LVD) shift in precipitation was significant and not homogeneous from 1990. Whereas, precipitation in highly vulnerable districts (HVD), both Pettitt’s test and Buishand test were not rejected and intensity of rainfall pattern has not changed over years from 2010. Wind speed in LVD was not homogeneous from 2000 and similar results were found for the HVD. Shift in relative humidity was statistically significant according to Buishand’s test in LVD and

not homogenous from 2015. In HVD results were found to be not significant. Maximum temperature in LVD is homogeneous since the null hypothesis for the Pettitts test was not rejected at 5 per cent level of significance and it was not statistically significant. Whereas, in highly vulnerable districts, it was found to be significant according to Buishand’s test and not homogenous from 2001.
