Impact of Changing Weather Patterns on Agriculture

However, there have been extreme weather events in the recent past including extended dry periods, floods, hailstorms, cyclonic rains and winds etc., which caused damage to standing crops and ultimately poor yield of crops.
The State Government is primarily responsible for taking necessary relief measures in the wake of natural calamities.
