El Niño Events Consistently Reduce Kharif Crop Yields Across India: ICAR Study
A study by scientists at the ICAR-Indian Institute of Farming Systems Research (ICAR-IIFSR), led by Subash N. Pillai, finds that El Niño events have consistently reduced yields of major kharif crops in India.
Paddy output fell by over 10% in 77 districts during El Niño years; maize production declined similarly in 65 districts.
The study underscores systemic vulnerability of India's rain-dependent kharif agriculture to ENSO (El Niño–Southern Oscillation) variability.
The findings have heightened concern given that NOAA's Climate Prediction Center places the probability of El Niño emergence at 61–62% for May–July 2026, persisting into 2026–27 at 72–80%.
Rainfed agriculture accounts for 51% of India's net sown area and contributes nearly 40% of total food production — making kharif yields a key determinant of food security and rural incomes.
El Niño–Southern Oscillation (ENSO): Mechanism and India Linkage
El Niño is the warm phase of the ENSO climate cycle, characterised by anomalous warming of surface waters in the central and eastern tropical Pacific Ocean. This disrupts the Walker Circulation — the east-west atmospheric circulation over the tropics — weakening the trade winds that drive moisture-laden air toward the Indian subcontinent. The result is typically a weakened Indian Summer Monsoon (June–September), producing below-normal rainfall and spatially uneven distribution across India.
The ICAR-IIFSR study quantifies what was previously known qualitatively — that El Niño episodes translate into measurable, district-level crop yield losses, providing policymakers with a science-based early-warning framework.
Kharif Agriculture: Cropping Pattern and Economic Significance
Kharif crops are sown with the onset of the southwest monsoon (typically June) and harvested after the monsoon withdraws (October–November). They require warm temperatures and rainfall during the growing season. Major kharif crops include: rice (paddy), maize, jowar (sorghum), bajra (pearl millet), cotton, soybean, groundnut, sugarcane, and pulses (tur/arhar, moong, urad).
The district-level granularity of the ICAR study enables targeted government interventions — drought-resistant variety deployment, insurance triggers under PMFBY, and procurement buffers — precisely in the 77 paddy and 65 maize districts most exposed to El Niño risk.
ICAR: Institutional Role in Agricultural Research
The Indian Council of Agricultural Research (ICAR) is an autonomous body under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers' Welfare. Established in 1929, ICAR coordinates, guides, and manages research, education, and extension in agriculture and allied sciences. It operates 113 institutes and 73 Krishi Vigyan Kendras (KVKs) across India. ICAR-IIFSR (Indian Institute of Farming Systems Research), Modipuram, focuses on integrated farming systems to improve productivity and sustainability across diverse agro-climatic zones.
ICAR-IIFSR's mandate to study integrated farming systems makes it the appropriate institution to assess systemic climate risks — such as ENSO impacts — across multiple crops and districts simultaneously.
Agricultural Risk Management: PMFBY and Price Support Mechanisms
India manages kharif crop risk through several policy instruments:
- Pradhan Mantri Fasal Bima Yojana (PMFBY), 2016: Provides comprehensive crop insurance at low premium (2% for kharif, 1.5% for rabi) with the balance borne by the Centre and state governments. Covers pre-sowing to post-harvest losses including cyclone and unseasonal rain.
- Minimum Support Price (MSP): Announced by Cabinet Committee on Economic Affairs (CCEA) based on Commission for Agricultural Costs and Prices (CACP) recommendations; covers 23 crops including all major kharif crops.
- Buffer Stock and Price Stabilisation Fund (PSF): Maintained by Food Corporation of India (FCI) for rice and wheat; enables government to intervene in markets when production falls.
- National Food Security Act, 2013: Legally mandates subsidised food grain to ~67% of India's population (75% rural, 50% urban) — making domestic production shortfalls a food security risk beyond just agriculture economics.
Key Details
- PMFBY launched: 2016; replaced the earlier NAIS and MNAIS schemes.
- PMFBY premium for kharif crops: 2% of sum insured (farmer share); balance subsidised.
- MSP covers: 14 kharif crops, 6 rabi crops, and 2 commercial crops (sugarcane via FRP).
- FCI buffer stock norms: Central Government maintains operational and strategic reserves for rice and wheat.
- NFSA 2013: covers approximately 813 million beneficiaries (as of 2022 data).
El Niño-induced kharif losses in 77 paddy and 65 maize districts would trigger PMFBY payouts and MSP procurement pressure simultaneously — a fiscal scenario that warrants advance preparation by the Ministry of Agriculture.
