These heat action plans, or HAPs, have been proliferating in India in the past few years. In general, an HAP spells out when and how officials should issue heat warnings and alert hospitals and other institutions. Nagpur’s plan, for instance, calls for hospitals to set aside “cold wards” in the summer for treating heatstroke patients, and advises builders to give construction laborers a break from work on very hot days.
But implementation of existing HAPs has been uneven, according to a March report from the Centre for Policy Research (CPR), a prominent Indian think tank. It reviewed 37 plans adopted by cities, states, or administrative districts.
Many lack adequate funding, it found. And their triggering thresholds often are not customized to the local climate, says Dileep Mavalankar, director of the Indian Institute of Public Health, who has been closely involved in Ahmedabad’s HAP. In some areas, high daytime temperatures alone might serve as an adequate trigger for alerts. Ahmedabad, for example, set its threshold for initial alerts at 41°C based on data showing that heat-related deaths began to climb at that point. But in other places, nighttime temperatures or humidity might be as important a gauge of risk as daytime highs.
Mumbai’s April heat stroke deaths highlighted the need for more nuanced and localized warnings, researchers say. That day’s high temperature of roughly 36°C was 1°C shy of the heat wave alert threshold for coastal cities set by national meteorological authorities. But the effects of the heat were amplified by humidity—an often neglected factor in heat alert systems—and the lack of shade at the late-morning outdoor ceremony. Ironically, the state of Maharashtra, which includes Mumbai, had adopted its own HAP just 2 months before the tragedy. It advised shifting outdoor events to early mornings on hot days.
To help improve HAPs, Kotharkar’s team is working on a model plan that outlines best practices and could be adapted to local conditions. Among other things, she says, all cities should create a vulnerability map to help focus responses on the populations most at risk. (The CPR study found that only two of the 37 HAPs it examined identified the most vulnerable populations.)
Such mapping doesn’t need to be complex, Kotharkar says. “A useful map can be created by looking at even a few key parameters.” For example, neighborhoods with a large elderly population or informal dwellings that cope poorly with heat could get special warnings or be bolstered with cooling centers. The Nagpur project has already created a risk and vulnerability map, which enabled Kotharkar to tell officials which neighborhoods to focus on in the event of a heat wave this summer.
HAPs shouldn’t just include short-term emergency responses, researchers say, but also recommend medium- to long-term measures that could make communities cooler. In Nagpur, for example, Kotharkar’s team has been able to advise city officials about where to plant trees to provide shade. HAPs could also guide efforts to retrofit homes or tweak building regulations. “Reducing deaths [in an emergency] is good target to have, but it’s the lowest [target],” Singh says.
