Climate change is the most important global environmental challenge faced by humanity with implication on natural ecosystem, agriculture and health. Climate change is affecting the country in a big way and its impacts are serious-erratic monsoon, spread of tropical diseases, sea level rise, changes in availability of fresh water, flood, drought, heat waves, storms, hurricanes etc. Rainfall is the primary medium through which climate change influences the earth’s ecosystems and therefore people’s livelihoods and well-being. Already, water-related climate change impacts are being experienced in the form of more severe and more frequent droughts and floods. Keeping the importance of rainfall for agriculture and climate change the present study was undertaken using secondary data, collected from various sources. For the study, data were analysed using trend analysis and regression analysis. Results of the study revealed that, rainfall had positive and significant relation with cultivable area in the case of Belgaum, Dharwad, Haveri, Bellary and Raichur districts. It indicates that as rainfall increases by one millimeter, area under cultivation in these districts increases by 0.28, 0.72, 0.21, 0.16 and 0.43 ha respectively. In the districts like Bagalkot, Bellary, Bidar, Bijapur, Gulburga and Raichur rainfall showed a decreasing trend. While in Belgaum, Dharwad and Uttar Kannada showed an increasing trend over the period from 1983 to 2012.  Complete forest area was converted to cultivable land in North-Karnataka. Land which was not available for cultivation was completely converted into fallow land. Non agriculture land was converted into fallow land (70.38%) and forest (24.28%). Fallow land was converted into forest (37.40%), non agriculture land (2.19%) and barren land (9.93%). Negative deviation in rainfall was more than the positive deviations in all the districts of North Karnataka. It indicated that, the districts of North Karnataka experienced more droughts as compared to floods
