GS-I (Climatology) and GS-III (Disaster Management, Agriculture). A very strong El Niño can weaken the southwest monsoon, hurting kharif output, food prices and rural incomes, while raising heat, drought and flood risks. Policy response involves IMD forecasting and early warning, contingency crop planning, buffer stocks and NDMA drought preparedness, with climate-resilient agriculture as the way forward.
