Context:

• The World Meteorological Organisation (WMO), the National Oceanic and Atmospheric Administration (NOAA) and other global scientific institutions have expressed high confidence in the possibility of a Super El Niño in 2026–27.
• El Niño is associated with the weakening of the Walker circulation, which can influence the Indian summer monsoon, agriculture, marine ecosystems and livelihoods.
• As the situation calls for proactive preparation, India's preparedness should therefore integrate climate adaptation, ecosystem-based disaster risk reduction and livelihood resilience.

Super El Niño - An Emerging Global Threat:

• High probability: Forecasts indicate a 97% probability of El Niño continuing into spring 2027, with NOAA assigning over 80% probability to it becoming a strong or very strong event.
• Exceptional intensity: Sea surface temperature anomalies could exceed 2°C in the key Pacific monitoring region, potentially reaching 4°C.
• Global consequences: Such an intense event, superimposed on long-term global warming, could intensify extreme weather and cause significant economic losses worldwide.

Implications for India's Climate and Agriculture:

• Disruption of the Indian Monsoon:
  • El Niño involves abnormal warming of the central and eastern equatorial Pacific Ocean, which alters atmospheric circulation and weakens the Indian summer monsoon.
  • Historically, strong El Niño events have coincided with severe droughts in India, including those of 1972, 2002 and 2009.
  • The 2026 event could aggravate existing rainfall deficits, particularly as the southwest monsoon has already performed below its long-period average.
• Threat to agricultural productivity:
  • Inadequate rainfall has already affected rice, pulses, cotton and maize production in several regions.
  • Low reservoir levels pose additional challenges for irrigation during the rabi season.
  • The combined effects of drought, heat stress and water scarcity could threaten agricultural productivity and rural livelihoods.

Ecological Consequences of Super El Niño:

• Impact on terrestrial ecosystems:
  • The effects of an exceptionally strong El Niño on India's forests, grasslands and riverine ecosystems remain poorly understood.
  • Changes in plant phenology (seasonal patterns of growth, flowering and fruiting), tree mortality, forest fires and animal behaviour require systematic monitoring.
  • Rising temperatures could further intensify existing ecological stress.
• Coral reef bleaching:
  • Higher ocean temperatures cause coral bleaching, potentially resulting in widespread coral mortality.
  • Researchers from the Nature Conservation Foundation (NCF) recorded a 50% decline in Lakshadweep's coral reefs between 1998 and 2025, although conservation efforts had helped some reefs recover.
  • The 1998 El Niño destroyed 80–90% of live coral on several studied Lakshadweep reefs.
  • More frequent and intense El Niño events could undermine recovery and threaten marine biodiversity.
• Marine heat stress and fisheries:
  • The Indian National Centre for Ocean Information Services (INCOIS) anticipates severe marine heat stress in the Arabian Sea and Bay of Bengal, potentially peaking around March 2027.
  • Rising sea temperatures could reduce the availability of commercially important fish, including sardines and mackerel.
  • This would threaten the livelihoods of millions of fishers and affect coastal economies.

India's Preparedness - Key Challenges:

• Inadequate ecological data: Despite decades of experience with El Niño, India lacks systematic, long-term data on its effects on terrestrial and marine ecosystems.
• Limited understanding of vulnerabilities: The impacts on farmers, pastoralists, fishing communities and ecosystem-dependent livelihoods remain insufficiently documented.
• Institutional fragmentation: Limited coordination among government agencies, researchers and conservation organisations restricts comprehensive monitoring.
• Insufficient field research: Large-scale remote sensing cannot fully capture local ecological changes and their socioeconomic consequences. On-site observations are essential.

Way Forward - Towards a Super El Niño Abhiyan:

• Strengthen scientific monitoring:
  • Establish real-time, field-based monitoring systems to track coral bleaching, forest mortality, wildfire risks, urban heat islands and changes in plant and animal behaviour.
  • Promote long-term ecological research to identify vulnerable ecosystems and understand their capacity for recovery.
• Promote institutional collaboration:
  • Bring together government agencies, public and private research institutions, conservationists and local communities.
  • Encourage interdisciplinary research integrating climate science, ecology, agriculture and social sciences.
• Mobilise resources and build resilience:
  • Provide urgent government funding and facilitate access to vulnerable ecosystems for scientific research.
  • Mobilise philanthropic investment to support ecological monitoring and community-based research.
  • Translate scientific findings into early-warning systems, disaster preparedness and locally appropriate adaptation strategies.

Conclusion:

• The potential Super El Niño presents India with an ecological and socioeconomic challenge that could be aggravated by climate change.
• A shift from reactive disaster management to proactive, evidence-based preparedness is essential.
• A proposed Super El Niño Abhiyan, combining scientific research, administrative coordination and community participation, could help strengthen India's ecological resilience and protect vulnerable livelihoods.
