When El Niño becomes an economic crisis
When El Niño Becomes an Economic Crisis
UPSC Prelims + Mains Study Note
1. At a Glance
- El Niño is the warm phase of the El Niño–Southern Oscillation (ENSO) cycle — a periodic warming of surface waters in the central and eastern tropical Pacific Ocean, which disrupts global atmospheric circulation and precipitation patterns. [S3]
- For India, El Niño is strongly associated with weakened southwest monsoon, sub-par rainfall, agricultural distress, food inflation, and GDP deceleration — making it simultaneously a meteorological, economic, and development challenge.
- NOAA's ENSO Diagnostic Discussion Report (2026) projects an 82% probability of El Niño emerging during May–July 2026 and a 96% probability of continuation through winter 2026–27, placing India on high climate-economic alert. [S5]
- IMD's Long Range Forecast (2026) projects monsoon rainfall at 92% of the Long-Period Average (LPA) — classified as "below normal" — directly threatening kharif output, food prices, and informal-sector livelihoods. [S5]
2. Why in the News
- NOAA's 2026 ENSO Diagnostic Discussion (released early 2026) flagged El Niño emergence with near-certainty probabilities for the critical May–July 2026 window. [S3]
- IMD's 2026 Long Range Forecast confirmed monsoon at 92% LPA — "below normal" — triggering concern across agri, fiscal, and monetary policy circles. [S5]
- FAO alert (2024–25): FAO flagged globally that "El Niño is coming for agriculture" and mapped highest-risk crop zones, with South Asia — including India — among the most vulnerable. [S2]
- Since March 2026, FAO's global agricultural and cereal price indices have risen 3% and 4% respectively, reflecting emerging supply anxieties. [S1]
- The Hindu article (5 June 2026) by economists from ICFAI and Amity University reframed El Niño as a "development crisis" — highlighting heat stress, water scarcity, crop losses, food inflation, and informal economy fragility. [S5]
3. Background & Evolution
| Period | Milestone |
|---|---|
| 1950s onward | ENSO systematically studied; El Niño named by Peruvian fishermen for anomalous warm current near Christmas. |
| 1982–83 | One of the strongest El Niños on record; global crop failures and economic losses. |
| 1997–98 | Most intense 20th-century event; India's 1997 kharif output severely hit. |
| 2002–03 | India: monsoon deficient by ~19%; severe drought across 14 states. |
| 2009 | Weakest monsoon since 1972 (77% LPA); India's food inflation spiked to ~18% YoY. |
| 2014–16 | Back-to-back El Niño events (2014–15, 2015–16); India experienced two consecutive deficient monsoons. In 2015, India's maize output fell 4%, rice output fell 1%. [S4] |
| 2023–24 | Strong El Niño emerged mid-2023; IMD recorded below-normal monsoon in 2023; kharif sowing disrupted; rice export ban imposed (August 2023). |
| 2025–26 | New El Niño cycle forecast by NOAA; IMD projects 92% LPA for 2026. [S3] |
- Predecessor: La Niña (cool phase of ENSO) typically causes excess rainfall in India; alternation between phases every 3–7 years drives India's drought-flood cycle.
- Indian Ocean Dipole (IOD): A positive IOD can partially counteract El Niño's suppression of the Indian monsoon — a key moderating factor in forecast uncertainty.
4. Core Static Facts
El Niño — Definitional Basics - Full form of ENSO: El Niño–Southern Oscillation - Threshold: Sea Surface Temperature (SST) anomaly of +0.5°C above average in the Niño 3.4 region (central tropical Pacific) for ≥5 consecutive 3-month periods. - Opposite phase: La Niña (SST anomaly ≤ −0.5°C) - Monitoring agency (global): NOAA (USA); WMO coordinates international outlook - Monitoring agency (India): India Meteorological Department (IMD), under Ministry of Earth Sciences (MoES) - Indian monsoon season: June–September (JJAS); contributes ~70% of India's annual rainfall - LPA (Long Period Average): 87 cm (for 1971–2020 baseline) - "Below Normal" classification: 90–95% of LPA [S5] - "Deficient" classification: <90% of LPA - Rice yield correlation: During 2015 El Niño, India's rice output fell ~1%, maize ~4% [S4] - Food in India's CPI basket: ~46% weight — making food inflation highly sensitive to monsoon shocks [S3] - India's agriculture GDP share: ~18% of GVA; employs ~45–47% of workforce (Census/NSSO) - Key vulnerable crops (kharif): Rice, coarse cereals (maize, bajra), pulses, oilseeds, sugarcane - El Niño → Sugar: 2026–27 El Niño forecast to reduce sugar output in India and Thailand, tightening global export availability [S1] - NOAA probabilities (2026): 82% (May–Jul 2026); 96% (winter 2026–27) [S5]
5. Multi-Dimensional Analysis
Economic
- El Niño causes short-lived falls in economic activity in India — confirmed by IMF research — through agricultural channel, demand compression in rural areas, and supply-side inflation. [S3]
- Food inflation surge: Countries with high food share in CPI (India: ~46%) experience larger inflation impacts from El Niño shocks; 2009 El Niño drove India's food inflation to ~18% YoY. [S3]
- Agricultural credit stress: Deficient monsoons raise probability of farm loan defaults (NPAs); rural NBFC and cooperative bank balance sheets deteriorate.
- Fiscal pressure: Government forced to raise procurement under NFSA, expand MGNREGS allocations, and consider input subsidies — crowding out capex.
Social
- Informal economy exposure: The Hindu article (June 2026) specifically flags that climate shocks move "quickly into the labour market, the mandi, the household kitchen" — disproportionately hitting informal workers (construction, daily wage agriculture). [S5]
- Heat stress on workers: Rising temperatures during El Niño years reduce outdoor labour productivity; ILO research estimates heat stress could cost India millions of full-time equivalent jobs.
- Nutritional impact: Below-normal kharif output reduces caloric availability; poor households shift to cheaper, less nutritious diets — compounding malnutrition indices.
- Women and vulnerable groups: Women-headed farm households, tribal communities dependent on rainfed agriculture, and coastal fisherfolk face amplified risk.
Environmental
- Groundwater depletion: When rainfall becomes uncertain, groundwater extraction intensifies (noted in the source article) — accelerating aquifer depletion, especially in Indo-Gangetic Plain. [S5]
- Wildfire risk: Dry, hot El Niño conditions elevate forest fire risk across Central India and Northeast India.
- Soil degradation: Droughts reduce vegetative cover → surface runoff and topsoil erosion increase during sporadic intense rain events.
- FAO notes El Niño-linked drought impacts crop and pastureland availability, with South Asia among highest-risk zones. [S2]
Geopolitical / Strategic
- Export restrictions: India's rice export ban (August 2023, during 2023 El Niño) created diplomatic friction with African and Southeast Asian countries dependent on Indian rice.
- Food inflation as strategic vulnerability: Domestic food price spikes can destabilise political economies; historically linked to rural unrest and policy volatility.
- Regional spillover: El Niño-driven distress in South Asia can drive climate migration across porous borders (Bangladesh, Nepal, Myanmar).
Administrative
- Sowing decisions: Uncertain rainfall makes kharif sowing riskier; farmers delay, reducing cropped area — translating weather uncertainty directly into supply-side shocks. [S5]
- Irrigation costs rise: Farmers shift to groundwater irrigation, raising input costs; electricity subsidy burden on state discoms increases.
- NDMA role: National Disaster Management Authority coordinates drought response; but drought is not declared until rainfall deficit crosses thresholds — causing lag in relief.
- Adaptation gap: Heat-resilient cities, worker protection frameworks, and advanced water management remain inadequate — a key prescription in the source article. [S5]
Scientific / Technological
- ENSO forecasting: NOAA's ENSO Diagnostic Discussion uses coupled ocean-atmosphere models; IMD's dynamical models now offer seasonal forecasts 4–5 months ahead.
- Cropping advisories: IMD issues Agrometeorological Advisory Services (AAS) to farmers via District Agrometeorological Units (DAMUs).
- Remote sensing: ISRO's satellite data (RISAT, Resourcesat) used for real-time drought monitoring and crop condition assessment.
6. Recent Developments (Last 12–18 Months)
- August 2023: India imposed non-basmati white rice export ban amid 2023 El Niño concerns and domestic price pressures — caused global rice price spike.
- 2023 Monsoon: IMD recorded below-normal monsoon in 2023 — linked to 2023–24 El Niño; kharif output missed targets in several states.
- Early 2024: 2023–24 El Niño declared to have peaked; La Niña transition forecast for late 2024.
- 2024 Monsoon: IMD forecast above-normal monsoon for 2024 (La Niña influence); largely materialised, providing some relief.
- 2025: Inter-ENSO neutral to weak La Niña phase; FAO noted ongoing food security stress globally.
- Early 2026: NOAA's ENSO Diagnostic Discussion (2026) projects El Niño re-emergence — 82% probability May–Jul 2026, 96% through winter 2026–27. [S3]
- IMD Long Range Forecast 2026: Monsoon at 92% of LPA — "below normal". [S5]
- March–June 2026: FAO's Food Price and agricultural commodity indices rise 3–4% since March 2026, reflecting supply anxieties. [S1]
- 5 June 2026: The Hindu article by economists from ICFAI (Hyderabad) and Amity (Chhattisgarh) makes the case for treating El Niño as a "development crisis", calling for heat-resilient cities, worker protection, and water management reform. [S5]
7. Prelims Hooks (High-Density Factual Bullets)
- El Niño is defined by SST anomaly of +0.5°C or more in the Niño 3.4 region of the central tropical Pacific for ≥5 overlapping 3-month periods.
- ENSO stands for El Niño–Southern Oscillation; the Southern Oscillation refers to the atmospheric pressure seesaw between Darwin (Australia) and Tahiti.
- India's Long Period Average (LPA) for monsoon rainfall is 87 cm (1971–2020 baseline).
- IMD classifies monsoon as "below normal" when rainfall is 90–95% of LPA; "deficient" when it is below 90% LPA.
- Monitoring of El Niño in India is the mandate of IMD, under the Ministry of Earth Sciences — NOT the Ministry of Environment, Forest and Climate Change.
- NOAA's ENSO Diagnostic Discussion (2026) gives an 82% probability of El Niño during May–July 2026 and 96% probability for continuation through winter 2026–27. [S3]
- During the 2015–16 El Niño, India's maize output fell ~4% and rice output fell ~1%. [S4]
- El Niño can reduce sugar output in both India and Thailand simultaneously — affecting global export availability. [S1]
- Food items account for approximately 46% of India's CPI basket — making India's inflation especially vulnerable to El Niño-driven agricultural shocks. [S3]
- MGNREGS serves as the primary fiscal stabiliser during El Niño-linked rural distress — demand for work under the scheme spikes during drought years.
- IMD's Agrometeorological Advisory Services (AAS) are delivered to farmers via District Agrometeorological Units (DAMUs).
- A positive Indian Ocean Dipole (IOD) can partially offset El Niño's suppression of the Indian southwest monsoon.
- IMD's Long Range Forecast for 2026 projects monsoon at 92% of LPA — placing it in the "below normal" category. [S5]
- FAO Food Price Index agricultural sub-index rose 3% and cereal sub-index rose 4% between March and June 2026. [S1]
- Countries with a higher share of food in CPI experience larger inflation responses to El Niño shocks — a finding from IMF research. [S3]

10. Common Errors / Trap Areas
- El Niño ≠ always bad for India: El Niño can benefit the northeast monsoon (October–December) in southeastern India (Tamil Nadu, Andhra coast) — examiners test this nuance. Do not generalise "El Niño = drought everywhere in India."
- Ministry confusion: El Niño monitoring and IMD fall under Ministry of Earth Sciences (MoES) — NOT MoEFCC (Ministry of Environment, Forest & Climate Change), which many aspirants conflate.
- "Below Normal" vs "Deficient": These are distinct IMD categories. 90–95% LPA = Below Normal; <90% LPA = Deficient. The 2026 forecast (92%) is "below normal", not "deficient." [S5]
- NOAA vs IMD role: NOAA provides global ENSO forecasts; IMD issues India-specific monsoon forecasts. They are not interchangeable — questions may test which body issues which forecast.
- El Niño ≠ only agricultural problem: A common mistake is to confine El Niño's impact to farming. The article and IMF research explicitly show its reach into labour markets, inflation, fiscal policy, groundwater, and export diplomacy — all fair game for GS-III.
