India updates disaster list to include heatwaves and lightning after Finance Commission push
Heatwaves and lightning have been added to India's list of notified natural disasters, taking the count of notified categories from 12 to 14
The change follows a recommendation of the 16th Finance Commission and has been incorporated into operational guidelines governing the State Disaster Response Fund (SDRF) and National Disaster Response Fund (NDRF) for the 2026-31 award period
States can now draw on full SDRF allocations, and NDRF support where required, for heatwave and lightning relief; previously, spending on heatwave relief was capped at 10% of a state's annual SDRF allocation
The revision follows a season in which heatstroke was linked to at least 20 deaths and close to 5,000 reported heatstroke cases across 13 states between March 1 and July 26, 2026
The Disaster Management Act, 2005 and "Notified Disasters"
The Disaster Management Act, 2005 defines a disaster under Section 2(d) as a catastrophe, mishap, calamity or grave occurrence arising from natural or man-made causes, causing substantial loss of life, property or environmental degradation. The Act does not itself enumerate specific hazard categories; instead, the Ministry of Home Affairs periodically "notifies" a list of eligible disasters for relief funding under the SDRF/NDRF framework, in line with Finance Commission recommendations for each award period.
Key Details
- Prior list of 12 notified disasters: cyclone, drought, earthquake, fire, flood, tsunami, hailstorm, landslide, avalanche, cloudburst, pest attack, and frost/cold wave
- Heatwave and lightning are now the 13th and 14th notified categories
- The National Disaster Management Authority (NDMA), headed by the Prime Minister, lays down the overarching policies, plans and guidelines for disaster management under the Act
The addition of heatwaves and lightning operationalizes the Finance Commission's recommendation by formally bringing these two hazards inside the DM Act's notified-disaster funding mechanism, unlocking full SDRF/NDRF eligibility rather than the earlier, capped local-disaster treatment.
SDRF and NDRF — The Two-Tier Disaster Financing Architecture
The State Disaster Response Fund (SDRF) is the primary fund for immediate relief, financed jointly by the Centre and states in a ratio recommended by the Finance Commission. The National Disaster Response Fund (NDRF), constituted under Section 46 of the DM Act, 2005, supplements a state's SDRF when a disaster is of a severe nature and state resources are inadequate; NDRF is funded entirely by the Centre.
Key Details
- SDRF Centre:State contribution ratio — 75:25 for most states, 90:10 for North-Eastern and Himalayan states
- NDRF contribution comes wholly from the Central Government
- SDRF instalments are released twice a year, typically in June and December, into a state's public account
Because heatwave and lightning relief was earlier restricted to a maximum of 10% of a state's annual SDRF allocation (as they were not "notified" hazards), formal notification now allows states unrestricted access to SDRF — and, in severe cases, top-up support from the NDRF — for these two hazards.
Role of the Finance Commission in Disaster Relief Funding
Under Article 280 of the Constitution, the Finance Commission's terms of reference include recommending the size and Centre-state sharing pattern of disaster relief funds for its award period. Each Finance Commission separately reviews which hazards merit inclusion in the notified list, based on frequency, severity and emerging climate risk.
Key Details
- The 15th Finance Commission (covering 2021-26) had declined to add heatwave and lightning to the notified list
- The 16th Finance Commission recommended their inclusion, citing the rising frequency and intensity of extreme weather events linked to climate change
- Finance Commission recommendations on disaster funding are typically accepted and operationalized through Ministry of Home Affairs guidelines for the corresponding award period
This is a direct instance of a Finance Commission recommendation reshaping the practical scope of disaster relief entitlements — a recommendation declined by the 15th FC has now been accepted for the 16th FC's 2026-31 cycle.
- Notified disaster categories: 12 (previous) → 14 (after adding heatwave and lightning)
- SDRF Centre:State funding ratio: 75:25 (general states), 90:10 (North-Eastern/Himalayan states)
- NDRF: constituted under Section 46, DM Act 2005; 100% Centrally funded
- Previous cap on SDRF spend for heatwave relief: 10% of annual allocation
- Heatstroke impact cited: at least 20 deaths, nearly 5,000 cases across 13 states (March 1–July 26, 2026)
- 15th Finance Commission declined heatwave/lightning inclusion; 16th Finance Commission recommended it for the 2026-31 period
