Delhi has no action plan to soften heatwave blow, yet
NEW DELHI: The mercury is set to soar this month, but the city currently has no heat action plan for minimising the impact of heatwaves that severely impact Delhiites, especially vulnerable community members.However, a Delhi government official said concerned departments have been asked to submit their plans by April 10. “A draft heat action plan has been prepared. Based on inputs received from departments, a plan will be finalised this month.” The Delhi state action plan on climate change for the current decade is also yet to be implemented. The capital was under the grip of 17 heatwaves last summer, but some locations saw more than 20 heatwave days. delhi heatwave Since the temperature is expected to rise from this month, experts emphasised that a heat action plan should be in place. Aditya Valiathan Pillai, associate fellow at Centre for Policy Research (CPR), said, “Delhi should issue a heat action plan as the city has a large heat-exposed population and dense urban environments that trap heat, particularly in unplanned neighbourhoods, every summer. This summer is predicted to be bad, and it won’t be the last.” He added, “The economic and health consequences of a heatwave that lasts a week or so with hot nights that prevent the body from recovering and a marginal increase in humidity could be devastating. Outdoor workers, including construction workers, traffic police, vendors and delivery agents, are among the vulnerable constantly exposed to heat and have the least flexibility to cope.” Pillai co-authored a CPR report, titled ‘How is India adapting to heatwaves?’ The report stated that heat action plans regularly include a heatwave warning system, including sharing alerts with vulnerable populations; means of coordination between government departments; an awareness, training and behaviour change component to reduce heat exposure; a list of short-term actions, focused on healthcare or changing work hours; and longer-term solutions, such as investing in infrastructure like cool roofs and water harvesting bodies, changes in agricultural practice or adjusting urban planning, including green corridors. Avikal Somvanshi, senior programme manager, urban lab, Centre for Science and Environment, said, “Unlike Ahmedabad and other cities, Delhi has no defined policy for dealing with heatwaves. Heatwaves have become even more problematic in cities due to urban heat islands. When the ambient temperature is 46-50 degrees Celsius, the surface temperature is about 64-65 degrees Celsius, which is highly dangerous for human health.” “When temperature crosses a certain limit, there should be a policy on providing cool and shaded spaces to workers and changing the outdoor working timings,” he added. Meanwhile, IMD plans to issue a heat-hazard analysis for the country, including Delhi, this summer. The department currently issues forecasts based on the maximum temperature and its departure from normal. The heat-hazard analysis will be calculated based on five meteorological factors -- relative humidity, minimum and maximum temperatures, wind speed and duration of heatwave spell.
