Tamil Nadu forms El Nino expert panel to assess climate risks in 2026-27
Synopsis
Tamil Nadu isn't waiting for El Nino to strike — it has already assembled a seven-member scientific panel drawn from Anna University, IIT Madras, and WRI India to map climate risks and recommend district-level mitigation strategies. The committee's two-year mandate signals a deliberate shift from reactive disaster response to anticipatory climate governance in one of India's most weather-exposed states.
Key Takeaways
The Tamil Nadu government constituted an Expert Advisory Committee via a Government Order dated 28 July to assess El Nino risks.
The panel will operate through financial years 2026-27 and 2027-28 .
It will assess impacts on rainfall patterns , drought conditions , and flood risk across vulnerable districts.
Members include experts from Anna University , IIT Madras , WRI India , and the Suganthi Devadason Marine Research Institute , Thoothukudi .
The committee will advise the Tamil Nadu Disaster Risk Reduction Agency on early warning systems and mitigation strategies.
The Tamil Nadu government has constituted an Expert Advisory Committee to scientifically evaluate the risks posed by a potentially strong El Nino weather phenomenon and recommend preparedness measures to minimise the impact of extreme weather events across the state. The panel was formally established through a Government Order issued by the Revenue and Disaster Management Department on 28 July.
Mandate and Scope
The committee has been tasked with monitoring evolving climatic conditions, assessing El Nino's likely effects on rainfall patterns, drought conditions, and related climate risks in Tamil Nadu. It will identify vulnerable regions, track rainfall and drought scenarios in real time, and recommend science-backed precautionary measures.
The panel will also advise the Tamil Nadu Disaster Risk Reduction Agency on strengthening early warning systems and improving overall disaster preparedness. It will remain operational through financial years 2026-27 and 2027-28.
Who Is on the Committee
The Additional Chief Secretary and Commissioner of Revenue Administration has been appointed chairperson. The panel brings together specialists from climate science, hydrology, disaster management, environmental planning, and urban resilience. Members include:
S. Kanmani, Head of the Centre for Climate Change and Disaster Management at Anna University; Prof. Balaji Narasimhan of the Hydraulics and Water Resources Engineering Laboratory at IIT Madras; M. Arivudai Nambi Appadurai, Director of Climate Resilience Practice at WRI India and a member of the Tamil Nadu Governing Council on Climate Change; Ramesh Ramachandran, Advisor to the Tamil Nadu Green Climate Company; R. Venkatesan, Expert Member of the State Environment Appraisal Committee; J.K. Patterson Edward, Director of the Suganthi Devadason Marine Research Institute, Thoothukudi; and R. Pradeep John, Senior Manager at Tamil Nadu Urban Infrastructure Financial Services Limited.
Why El Nino Warrants a Dedicated Panel
El Nino events — characterised by anomalous warming of the central and eastern Pacific Ocean — have historically disrupted the Indian monsoon, triggering uneven rainfall distribution, prolonged dry spells, and heightened drought or flood risk across peninsular India. Tamil Nadu, with its dual-monsoon dependence and a significant agrarian population, is among the states most exposed to such variability.
This comes amid growing concern among meteorologists that the current El Nino cycle could intensify later in the year. The committee's formation signals that the state is moving from reactive disaster response toward structured, anticipatory climate governance — a shift that experts have long advocated.
Mitigation Strategies and Next Steps
Beyond monitoring, the expert body is mandated to recommend drought and flood mitigation strategies specifically tailored to vulnerable districts, ensuring that line departments are operationally ready for rapidly changing climatic conditions. The panel's findings are expected to feed directly into the state's disaster preparedness roadmap for the next two financial years.
With its two-year operational window, the committee's work will be closely watched as a model for how Indian states translate climate science into actionable policy ahead of extreme weather events.
Point of View
Not before one. The panel's cross-disciplinary composition, spanning hydrology, marine science, urban infrastructure, and international climate finance, suggests the government is serious about depth rather than optics. The real measure will be whether the committee's recommendations translate into funded district-level action plans, or remain advisory documents that gather dust. Given Tamil Nadu's track record of cyclone preparedness, there is reason for cautious optimism — but El Nino-linked drought is a slower, less visible emergency than a cyclone, and institutional attention tends to wane without a dramatic trigger.

Frequently Asked Questions
Why has Tamil Nadu formed an El Nino expert committee?
Tamil Nadu constituted the Expert Advisory Committee on 28 July to scientifically assess the risks of a potentially strong El Nino event and recommend preparedness and mitigation measures. El Nino events can disrupt monsoon patterns, increase drought risk, and cause uneven rainfall across the state.
Who are the members of Tamil Nadu's El Nino expert panel?
The committee is chaired by the Additional Chief Secretary and Commissioner of Revenue Administration and includes experts from Anna University, IIT Madras, WRI India, the Tamil Nadu Green Climate Company, the State Environment Appraisal Committee, the Suganthi Devadason Marine Research Institute in Thoothukudi, and Tamil Nadu Urban Infrastructure Financial Services Limited.
How long will the expert committee remain active?
The panel is mandated to function through financial years 2026-27 and 2027-28, giving it a two-year operational window to monitor climatic conditions and guide state disaster preparedness.
What will the committee actually do?
It will monitor rainfall and drought scenarios, identify vulnerable regions, recommend precautionary measures, advise the Tamil Nadu Disaster Risk Reduction Agency on early warning systems, and suggest district-level drought and flood mitigation strategies based on scientific assessment.
How does El Nino affect Tamil Nadu specifically?
El Nino events are associated with suppressed southwest monsoon rainfall and erratic northeast monsoon patterns, increasing the risk of prolonged dry spells, drought, and in some cases flash flooding in Tamil Nadu. The state's dependence on both monsoon cycles and its large agrarian population make it particularly vulnerable to El Nino-driven weather extremes.
