This book titled "Impact of Climate Variability on Agriculture" Deals with retrospective climate variability and its current impacts on rainfed rice farming in Asian context; predicts future 50 years possible climate variability through intercomparison of GCMs and predicts the fate of rice agriculture based on the predicted variability. This study would serve as a milestone for further studies and a contribution for designinging practical climate change/variability adaptation strategies to minimize adverse effects of climate variability on agriculture
