Description Rainfall data from 1979-2019 was analysed across the agro climatic zones in transition region of
Karnataka. Rainfall Anomaly Index and Mean deviation methods are used to identify drought years
and wet years over both spatial and temporal on time scale. The North Eastern Transition Zone
can be considered as most vulnerable zone as it recorded for about 24 dry years values which
indicates existence of persistence drought in this zone. The Northern Transition Zone is not
vulnerable when compared to Northern Eastern Transition Zone as most of the drought year
values are nearer to wet year values (RAI -0.3 to -1.2) which implies that this zone has moderate
drought condition. The Southern transition zone has normal drought condition (RAI +0.3 to -0.3)
which implies neither wet nor neither dry condition. But if proper conservations were not taken, this
zone may come in the hit list of most vulnerable zone in near future which will harm the farming
community.
