El Niño 2026 OND Forecast: India's Rabi Crops, Wheat, and Winter Agriculture at Risk

Why in News

The World Meteorological Organization (WMO) and India Meteorological Department (IMD) have confirmed that El Niño conditions are intensifying rapidly and forecast to peak during the October–December (OND) 2026 quarter, with sea surface temperature (SST) anomalies in the Niño 3.4 region reaching approximately +3.6°C above average — qualifying as a "very strong" El Niño event. WMO estimates near-100% probability of El Niño continuing through February 2027. This threatens India's Rabi (winter) crop season, particularly wheat, chickpea, mustard, and lentils, through below-average winter rainfall in northwest India and above-normal temperatures during the grain-filling stage.

Background: What is El Niño?

El Niño (Spanish for "the boy child," referring to the Christ child, as it was historically noticed around Christmas) is a climate phenomenon characterised by anomalous warming of sea surface temperatures (SSTs) in the central and eastern equatorial Pacific Ocean. It is part of the ENSO (El Niño-Southern Oscillation) cycle, which also includes La Niña (cooling phase) and neutral conditions.

El Niño is formally defined when SST anomalies in the Niño 3.4 region (5°N–5°S, 120°W–170°W) exceed +0.5°C for at least five consecutive overlapping three-month periods. A "strong" El Niño exceeds +1.5°C; "very strong" exceeds +3.0°C. The 2026 event, at ~+3.6°C, is among the strongest on record — comparable to the extreme 1997-98 and 2015-16 events.

Current Developments

WMO Global Seasonal Climate Update (SON 2026): Niño 3.4 SST anomaly at +3.6°C during September-November 2026 — "very severe" El Niño category. Sub-surface temperatures recorded over 8°C above average in some areas during July-August 2026, indicating rapid intensification.

IMD forecast:

• 2026 Southwest Monsoon: 90% of Long Period Average (LPA) — first below-normal monsoon since 2023
• Deficient monsoon probability: 35% (more than double the historical average)
• El Niño "likely to intensify during Oct-Dec and reach 'very severe' category"
• Above-normal temperatures forecast for most of India through the Rabi season

Positive Indian Ocean Dipole (IOD) co-factor: A positive IOD (western Indian Ocean warmer than eastern) is developing alongside El Niño (IOD index ~+0.9°C). This may partially moderate rainfall impacts over peninsular India but does not offset El Niño's impact on northwest India's Rabi belt.

Impact on India's Rabi Agriculture

India's Rabi season runs from October (sowing) to March-April (harvest). Principal Rabi crops are wheat (major food security crop; India is world's 2nd largest producer), chickpea (gram/chana; India produces ~70% of world supply), mustard/rapeseed, and lentils.

El Niño impacts Rabi agriculture through:

1. Low soil moisture at sowing: Below-normal Kharif-season rainfall leaves depleted soil moisture and reservoir levels at the onset of Rabi sowing (October)
2. Reduced winter rainfall (western disturbances): North-west India depends on western disturbances (mid-latitude cyclones from the Mediterranean) for winter moisture. El Niño weakens western disturbances, reducing January-February rainfall in wheat-growing states (Punjab, Haryana, UP, Rajasthan)
3. Above-normal temperatures during grain-filling: High temperatures in February-March cause premature grain maturation and yield loss in wheat (heat stress during grain-filling is the primary climate-yield vulnerability for Indian wheat)
4. Reduced irrigation water: Below-normal monsoon → lower reservoir and groundwater levels → reduced irrigation availability for Rabi crops

The Agriculture Ministry has directed states to prepare contingency plans, promote water-efficient irrigation (drip/sprinkler), and ensure early sowing of short-duration wheat varieties to escape late-season heat stress.

Constitutional Provisions

Article 48 (DPSP): State to organise agriculture on modern and scientific lines. Article 21: Right to life, interpreted by the Supreme Court (PUCL v. Union of India, 2001) to include the right to food — making food security from Rabi crop production a constitutional imperative. Article 253: Parliament's power to legislate for implementing international treaties — India's WMO membership obligations flow through this article.

Legal Framework

• National Food Security Act, 2013 — mandates subsidised food grain for 75% rural / 50% urban population; Rabi wheat is the primary input for PDS stocks
• Disaster Management Act, 2005 — NDMA is responsible for drought disaster preparedness and relief; El Niño-induced drought triggers NDRF deployment and crop loss compensation
• Pradhan Mantri Fasal Bima Yojana (PMFBY) — crop insurance scheme covering Rabi crops against weather risks including drought and heat

Institutional Framework

• India Meteorological Department (IMD) — national weather service; issues seasonal, short-range, and crop-weather outlooks; under Ministry of Earth Sciences
• World Meteorological Organization (WMO) — UN specialised agency for meteorology; issues Global Seasonal Climate Updates (GSCU); headquartered in Geneva
• Ministry of Earth Sciences (MoES) — nodal ministry for IMD, INCOIS, IITM (Pune); coordinates monsoon research and climate services
• IITM Pune (Indian Institute of Tropical Meteorology) — leads India's ENSO/El Niño research and CGCM-based seasonal forecasting
• National Disaster Management Authority (NDMA) — coordinates drought response, contingency planning
• Ministry of Agriculture and Farmers' Welfare — issues crop contingency plans, Kisan advisories, MSP-based procurement buffers

Economic Dimensions

Agriculture contributes approximately 17-18% of India's GDP and employs ~46% of the workforce. A significant Rabi crop failure can cause:

• Food inflation: Wheat and edible oil (mustard) prices rise with reduced domestic supply; CPI food inflation can spike 2–4 percentage points
• Import burden: India may need to increase wheat imports (as in 2022 post-Ukraine war supply shock), straining foreign exchange reserves
• Farmer income stress: Crop loss reduces rural disposable income, dampening consumption demand
• Fiscal pressure: Government may need to increase MSP procurement, subsidy payouts, and drought relief — widening fiscal deficit

Banking & financial angle: Agricultural loan NPAs (Non-Performing Assets) rise with crop failure; RBI's priority sector lending norms require banks to restructure Kisan Credit Cards (KCC) in drought-declared districts. NABARD activates its Short-Term Credit Refinance window to support cooperative credit flow during distress seasons.

Environmental Dimensions

El Niño intensifies under climate change: IPCC AR6 projects that strong El Niño events will become more frequent and intense. The 2026 event coincides with record global surface temperatures (2026 on track to be the hottest year on record, per WMO). Positive feedback loops — El Niño → drought → wildfire → carbon release → more warming — are now well-documented. India's National Action Plan on Climate Change (NAPCC) addresses agriculture adaptation through the National Mission for Sustainable Agriculture (NMSA).

Social Dimensions

Rabi crop failures historically correlate with rural distress migration, farmer suicides (particularly in rain-fed dryland areas), and increased demand for MGNREGS (Mahatma Gandhi National Rural Employment Guarantee Scheme) employment guarantee — as farmers seek wage income when crop income fails. The 2015-16 El Niño event was associated with a 20% increase in MGNREGS demand in drought-affected districts.

Way Forward

NITI Aayog's Climate Vulnerability Index ranks Indian districts by climate risk — states should prioritise pre-emptive Rabi crop diversification away from water-intensive crops in high-risk districts. PMFBY enrolment for Rabi 2026-27 must be fast-tracked, with state governments waiving premium contributions for small/marginal farmers in high-risk districts. IITM Pune's seasonal forecasting capability should be linked to Agri-Stack (India's digital agriculture platform) to deliver block-level crop advisory to farmers via PM-KISAN beneficiary databases.

FAQ

What is the difference between El Niño and La Niña?

El Niño involves anomalous warming of the central/eastern equatorial Pacific (SST anomaly >+0.5°C), typically suppressing India's monsoon. La Niña involves anomalous cooling (-0.5°C), typically enhancing India's monsoon. Both are phases of the ENSO (El Niño-Southern Oscillation) cycle.

What is the Indian Ocean Dipole (IOD) and how does it interact with El Niño?

IOD measures the SST difference between the western and eastern Indian Ocean. A positive IOD (warmer west) can partially offset El Niño's suppressive effect on the Indian monsoon — as seen in 2019, when a positive IOD moderated an El Niño year's monsoon impact. In 2026, a positive IOD (0.9°C) provides partial buffering for peninsular India.

What is the Niño 3.4 region?

The Niño 3.4 region (5°N–5°S, 120°W–170°W) in the central equatorial Pacific is the standard monitoring area for ENSO. When SST anomalies here exceed +0.5°C for five consecutive three-month periods, El Niño is declared.
