Climate and disaster resilience

Preparing communities, emergency services and infrastructure for heat, floods, droughts, earthquakes, industrial accidents and other disasters.

What is climate and disaster resilience?

Climate and disaster resilience is sub-pillar 8.5 of the 47 BH framework for a developed Bharat by 2047, the last of five sub-pillars under the Nature pillar and the last of the framework's 47. It asks whether communities, emergency services and infrastructure are ready for heat, floods, droughts, earthquakes, industrial accidents and the other disasters that a warming climate and a crowded country make more likely.

Why it matters for 2047

India will become developed in a hotter, wetter and more violent climate than the one in which every other country did. Heatwaves that were once rare are now annual, rains fall in fewer and fiercer bursts, the Himalaya is unstable and the coasts face stronger storms on rising seas. Resilience is no longer a specialist concern; it is the condition of everything else the framework hopes for.

Disasters are unequal. They kill the poor, the old, the outdoor worker and the farmer first, and they undo in a day what took a family a decade to build. A country that cannot protect its people from the weather cannot keep them out of poverty however fast it grows.

India has already shown what preparation can do: cyclones that killed tens of thousands a generation ago now kill dozens, because warnings reach the coast and people are moved in time. The task for 2047 is to do for heat, floods and the slow disaster of drought what has been done for cyclones.

Where India stands

  • 2,803

    people died in hydro-meteorological disasters in India in 2024-25, with Madhya Pradesh (373), Himachal Pradesh (358) and Gujarat (230) the worst affected; 3.47 lakh houses were damaged, 58,835 cattle lost and 10.23 lakh hectares of crops hit, according to the Ministry of Home Affairs.[1]

  • 730

    deaths from heat or sun stroke were recorded by the National Crime Records Bureau in 2022, in a series that ran from 1,216 in 2013 to a peak of 1,908 in 2015; the figures are widely regarded as undercounts, and the government's three agencies that count heat deaths disagree by thousands.[2][4]

  • 23

    heatwave-prone states had Heat Action Plans in force by 2025, implemented with the National Disaster Management Authority, with warnings issued through the Common Alerting Protocol and a district-wise heatwave vulnerability atlas, according to the Ministry of Earth Sciences; there is no official count of districts or cities with their own plans.[3]

  • 3

    official counts of India's heatwave deaths for 2000 to 2020 give three different totals: 20,615 (NCRB), 17,767 (NDMA) and 10,545 (IMD), a gap that an independent analysis attributes to different methods and reporting lines, and that makes the true toll unknowable from official data.[4]

India's disaster machinery has saved lives where it has been built. Early warnings for cyclones and floods reach phones through the Common Alerting Protocol, 23 states have heat action plans, the Meteorological Department publishes district-level vulnerability maps, and relief funds are released in the thousands of crores each year. [1][3] Cyclone deaths, once counted in tens of thousands, are now in the dozens.

The country still does not know how many of its people the weather kills. Three official agencies give three heat death totals that differ by half, and the annual police count, in the hundreds, sits beside independent estimates in the tens of thousands. [2][4] Nearly three thousand died in floods, landslides and storms in a single year, and 3.5 lakh homes were damaged. [1] Preparedness is uneven: the states with plans are not always the ones with the heat, and India has no measure of what share of its people receive a warning before a disaster strikes.

A note on the numbers: disaster deaths are compiled by the Home Ministry from state reports and cover hydro-meteorological events only, not earthquakes or industrial accidents, for which 47 BH has not yet found a consistent national series; heat deaths are counted differently by the police, the disaster authority and the weather office, and all three count only deaths certified as heatstroke, missing the far larger number that heat causes through heart and kidney failure; the heat action plan count is of states, not of the districts and cities where plans are actually implemented; early-warning coverage is not published. Economic losses from disasters are not reported in a form 47 BH could cite, and will be added when they are.

On the 47 BH report card

Every 15 August, 47 BH reports how far India has come on each sub-pillar. For this sub-pillar, the headline indicators are:

  • Deaths and economic losses from disasters, by type (Ministry of Home Affairs; NDMA; EM-DAT).
  • Heat deaths on a single reconciled official series (NCRB, NDMA and IMD).
  • Districts and cities with heat action plans and flood plans in force (NDMA; state authorities).
  • Share of population receiving early warnings before disasters (IMD; Common Alerting Protocol).

Two lenses on climate and disaster resilience

City and village

47 BH asks whether the construction worker on a city site at two in the afternoon and the farmer in a field at the same hour are protected from the same heat, and whether either gets a warning. Cities trap heat and flood when drains fail; villages lose crops and cattle and have further to go for help. The vulnerability atlas exists; the question is who acts on it.

Learn, avoid, protect

Learn
What can India learn from countries that count every heat death and act on the count, that built flood defences and drainage for the rains of the future rather than the past, and that made every new building, road and power line able to withstand the climate it will live in?
Avoid
Which mistakes should it avoid, such as treating disasters as acts of God rather than failures of preparation, writing plans that no district reads, or rebuilding after every flood exactly what the flood destroyed?
Protect
What of its own should it protect, such as the cyclone warning and evacuation system that is among the best in the developing world, the community networks that are the first responders in every disaster, and the traditional knowledge of floodplains, water harvesting and heat-adapted building that modern construction has forgotten?

Questions about climate and disaster resilience

How many Indians die in disasters each year?

2,803 people died in hydro-meteorological disasters in 2024-25, with Madhya Pradesh, Himachal Pradesh and Gujarat worst affected, and 3.47 lakh houses were damaged, according to the Ministry of Home Affairs in the Lok Sabha. Earthquake and industrial accident deaths are not in this series. [1]

How many people die of heat in India?

The National Crime Records Bureau recorded 730 heat or sun stroke deaths in 2022 and a peak of 1,908 in 2015, but official agencies disagree: for 2000 to 2020 the NCRB counted 20,615, the NDMA 17,767 and the IMD 10,545, and independent researchers estimate the true toll from heat-related illness is many times higher. [2][4]

How many states have heat action plans?

23 heatwave-prone states, implemented with the National Disaster Management Authority, according to the Ministry of Earth Sciences in the Rajya Sabha in 2024 and 2025; there is no official count of districts or cities with plans. [3]

Does India have early warning systems?

Yes. The Meteorological Department issues seasonal, monthly and extended-range forecasts, warnings go out through the Common Alerting Protocol to mobile phones, and a district-wise heatwave vulnerability atlas and a climate hazard atlas exist, according to the Ministry of Earth Sciences. What share of the population actually receives a warning in time is not published. [3]

Why is disaster resilience a development question?

Because a developed country is one its people can survive the weather in. India will build its 2047 in a climate harsher than any that built the rich world, and every road, home, farm and city it adds must be made for that climate or be lost to it.
