In Summary

Following the 16th Finance Commission's recommendations, the Centre formally added heatwaves and lightning to the notified natural calamities list.

About the List

  • Statutory Framework: Maintained under the Disaster Management Act, 2005, governing the National and State Disaster Response Funds (NDRF/SDRF).
  • Notified Entries: The notified list (now 14) comprises cyclone, drought, earthquake, flood, tsunami, avalanche, cloudburst, landslide, hailstorm, fire, frost/cold wave, pest attack, heatwave, and lightning.

About the New Inclusions

  • Heatwave: The IMD declares a heatwave when the maximum temperature reaches ≥40°C in plains or ≥30°C in hills, accompanied by a ≥4.5°C departure from normal.

  • Lightning: A sudden atmospheric electrical discharge, among India's leading causes of weather-related fatalities.

Significance of the Inclusion

  • Proactive Mitigation: Unlocks the 20% State Disaster Mitigation Fund for climate resilience infrastructure.
  • Policy Standardization: Creates a uniform framework for immediate relief and central support.

Mechanisms Against These Disasters 

  • NDMA Guidelines: National protocols on heatwave and lightning risk reduction, preparedness, and response.
