GS-I Geography and GS-III Agriculture: a deficient monsoon hits kharif sowing, reservoir storage and rural incomes, while uneven spatial and temporal distribution matters as much as the seasonal total. IMD forecasting and LPA-based classification guide policy, and the way forward lies in contingency crop planning, better water management, crop insurance and climate-resilient agriculture.
