To analyse the variations in climatic parameters like Rainfall and Temperature, data were used for a period of 1986-2016, and Humidity data were used for a period of 2000-2016 to study the nature of climate change in the region. The findings of the study show that the climate variability and climate change for Mysore district, the monthly Rainfall is increased and monsoon Rainfall shows a decrease in trend. And the monthly, summer, monsoon minimum Temperature shows that decrease. Generally, the monthly maximum Temperature has decreased, but in case of summer and monsoon seasons increased respectively, and the monthly Relative Humidity has increased (positive). There is a decrease in Relative Humidity from January to April, and increase in the Relative Humidity during Monsoon season for Mysore District. The Annual average of Relative Humidity shows that it is increased for Mysore District.

The study was conducted on respondents of 7 taluks of Mysore District. The sample size representative of the respondents in this study is 384. It is determine based on the Krejcie and Morgan's sample size calculation which same as using the Krejcie and Morgan's sample size determination table. The Krejcie and Morgan's sample size calculation was based on p = 0.05 where the probability of committing type I error is less than 5 % or p < 0.05, the results identified that More than half of the respondents (55.00 %) had medium level of knowledge on climate change. Majority (59.00 %) of the respondents followed medium level of adaptation measures followed by low (22.00 %) and high (19.00 %) levels. More than one third of the respondents were involved in restoring of existing wet lands (95.00) to adapt with climate change. Majority of the farmers had been sowing salt tolerant rice varieties (91.50 %) to adapt with climate change. Addition of organic matter (64.00 %) was the major adaptation measure taken by the respondents with soil condition against climate change. Increase irrigation water use efficiency (72.50 %) was the major practice followed by majority of the respondents to adapt with climate change. Majority of the farmers were practiced application of green manure (91.00 %) to adapt with climate change. Around half of the respondents were followed additional pesticide (51.00 %) for adaptation to climate change. Around 51.00 per cent of the respondents were invested more in Dairy activity other than the investment in agriculture and around fifty per cent of the respondents expressed that availing crop insurance (52.5 %) low investment in agriculture (49.5 %) and increased savings/ deposits (49 %) have helped the farmers to adapt with climate change. Majority of the respondents were approaching other farmers to get farm opinions (89.50 %) to get more information on farming activity with respect to climate change.
