May 2010 brought 1,344 more deaths than a normal May. The answer was not hardware: a forecast above 41°C went to a named officer, and each colour band said who had to do what.

After a May 2010 heat wave that peaked at 46.8°C and left an estimated 1,344 excess deaths, Ahmedabad wrote what the peer-reviewed literature calls South Asia's first heat-health action plan. Its 2013 pilot ran on seven-day probabilistic forecasts from Georgia Tech; since 2016 the India Meteorological Department has supplied the city's maximum-temperature forecasts. In the evaluated years a forecast of 41–42.9°C triggered a yellow alert, 43–44.9°C an orange one, and 45°C or above a red one. A nodal officer in the AMC health department coordinates the named actions; in March 2026 these included oral rehydration at every urban health centre, separate heatstroke beds at the municipal general hospital and a 1–4 pm stop on engineering work sites.

Live 📅 since 2013

📊 Impact

A pre/post evaluation published in 2018 compared 2007–2010 with 2014–2015 and found the all-cause mortality rate ratio at 47°C fell from 2.34 (95% CI 1.98–2.76) before the plan to 1.25 (95% CI 1.02–1.53) after it, estimating 1,190 (95% CI 162–2,218) annualised deaths avoided. The design is ecological: it cannot separate the plan from everything else that changed in those years, and the authors call it a pilot evaluation. Heat deaths are not a notifiable disease in India, so the low counts of reported heat deaths the city has cited in later summers cannot show the plan's effect on their own.

🎓 Lesson

The plan bought almost no sensing. What it built was an addressee — a forecast, a numbered threshold, and one official whose job is to act on it. Cities that buy the measurement and leave the last step unassigned end up with a reading nobody owns.

Caveat
An ecological pre/post design cannot separate the plan from everything else that changed over those years, and the authors describe it as a pilot evaluation rather than a causal estimate.
