El Niño and India’s economy: From monsoon risk to macroeconomic challenge

El Niño, the periodic warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean, is not merely a distant climatic event but a significant economic concern for India. By altering global atmospheric circulation, it weakens the Indian Southwest Monsoon, which remains the backbone of the country’s agriculture and rural economy.

During El Niño years, weakened trade winds reduce the movement of moisture-bearing winds towards the Indian subcontinent, often resulting in below-normal rainfall. Since nearly 70 per cent of India’s annual rainfall occurs during the monsoon season, any deficiency affects agriculture, reservoir storage, and groundwater recharge, triggering widespread economic consequences.

The agriculture sector is particularly vulnerable because nearly half of the net sown area depends on rainfall. A weak monsoon disrupts the cultivation of major kharif crops such as rice, cotton, soybeans, and pulses. Farmers often compensate by increasing groundwater extraction, raising irrigation costs through greater diesel and electricity consumption. Reduced crop yields combined with higher input costs diminish farm incomes and intensify rural distress, especially among small and marginal farmers.

Lower agricultural production soon translates into shortages of essential food items, pushing up the prices of cereals, vegetables, and pulses. Since food constitutes a major component of India’s Consumer Price Index (CPI), rising food prices contribute significantly to inflation. Higher household expenditure on necessities reduces discretionary spending, slowing overall economic demand.

El Niño also intensifies heat stress. Outdoor workers in agriculture, construction, and the informal sector experience lower productivity and reduced working hours during extreme heat conditions. Urban areas face additional challenges due to the Urban Heat Island effect caused by excessive concrete structures and reduced green spaces. While affluent populations can adapt through air conditioning and better infrastructure, economically weaker communities face greater health and livelihood risks.

The combined effect of lower growth and rising inflation can create a stagflation-like situation. Declining agricultural output weakens rural demand, while food inflation places pressure on monetary policy. The Reserve Bank of India (RBI) faces a difficult balance between controlling inflation through higher interest rates and supporting economic growth. Climate-related disruptions, along with global uncertainties and rising input costs, could moderate India’s economic growth.

The dangers of severe El Niño events are evident from history. The Great Famine of 1876–78, associated with prolonged monsoon failure linked to El Niño, caused millions of deaths across colonial India. Regions including the then Nizam’s Dominions, the present-day Telangana, suffered heavily, highlighting how climatic disturbances can transform into humanitarian disasters when societies lack resilience.

El Niño is a phase of the El Niño–Southern Oscillation (ENSO), a natural climate cycle. During El Niño, weakened trade winds allow warm Pacific waters to shift eastward, disturbing weather patterns across the globe. This leads to droughts in Australia and Southeast Asia, floods in parts of the Americas, reduced marine productivity, and weakened monsoon activity in India.

Climate forecasts indicate a possibility of El Niño conditions emerging in the coming years, increasing concerns over monsoon variability and economic stability. Therefore, managing El Niño risks requires a shift from crisis response to long-term climate adaptation.

India must strengthen drought-resilient agriculture by promoting millets, pulses, and oilseeds, expanding efficient irrigation systems such as drip and sprinkler technologies, and restoring traditional water bodies. Improved crop insurance, early warning systems, and rural financial protection are essential for reducing farmers’ vulnerability. In urban areas, heat action plans, increased green cover, wetland restoration, and cool roof technologies can reduce the impacts of extreme temperatures.

El Niño should be viewed not only as a meteorological event but as a systemic economic challenge affecting agriculture, inflation, labour productivity, and economic planning.

The lessons from historical famines and increasing climate uncertainty underline the need for a proactive strategy that integrates climate resilience into agriculture, urban development, and national economic policy.
