The mean annual rainfall over different stations of North Eastern dry zone of Karnataka varied between 630.1 mm to 744.3 mm. The mean annual rainfall received relatively more at North side and middle of the zone in comparison to south side lying stations within the North Eastern dry zone of Karnataka. The percentage of seasonal rainfall contribution towards annual rainfall varied between 66-74%, 16-20% and 10-14% for Kharif, rabi and summer seasons respectively. The drought characterization revealed that, out of 35 years (1986-2020) of study period, all the stations have experienced one or the other kind of drought situation during 17 to 20 years which accounts for 49 to 57 per cent, which means, most of the stations have experienced either mild or moderate drought conditions for 50% of the years.
