Many parts of India have been experiencing dangerous heat over the past few weeks, with multiple regions under alerts for extremely severe heat. Recent conditions are part of a broader trend that could make 2024 the hottest year on record for the country (closely following 2023, which was the hottest year globally since recordkeeping began). April 2024 saw some of the highest temperatures ever recorded nationally, with readings in a few locations reaching as high as 50∘C (122∘ F).
Intense heat is driving increased power demand, and the recently concluded Lok Sabha elections heightened the likelihood of heat-related health harms. The perils of extreme heat are expected to increase as climate change causes a rise in global temperatures. This danger is especially worrying for South Asia, where a recent heatwave was deemed 45 times more likely because of climate warming. The risks will be further exacerbated for vulnerable communities, such as the elderly, people lacking access to air conditioning, low-income populations, and informal sector and outdoor workers. To counter this threat, multiple strategies, including passive cooling methods, the addition of green spaces, and the establishment of public cooling stations, can offer thermal relief for vulnerable individuals during peak heat hours.
Jodhpur’s Heat Action Plan Advances Novel Cooling Station
Northwestern India is increasingly confronting intense heat risks. On May 19, 2016, the village of Phalodi (a town in the Jodhpur district) logged the highest daytime temperature reading ever recorded in India at 51°C (123.8 °F) — an observation that ranked third highest among global temperatures that day. Following that record high, NRDC, along with Mahila Housing Trust (MHT) and Jodhpur Nagar Nigam North (JNNN), initiated consultations for the development of a local Heat Action Plan (HAP) to improve local preparedness and reduce health harms from the intensifying heat problem.
Our organizations, working closely with JNNN, developed and launched Jodhpur’s HAP in 2023. The Jodhpur HAP has advanced several innovations, including data-driven spatial vulnerability assessment that clarifies, for the first time, how local heat risks vary ward by ward. To complement this local perspective, India’s National Disaster Management Authority (NDMA) aids in the implementation of HAPs by providing the data that inform detailed temperature forecasts and heat-health early warning systems.
In its second year of implementation, Jodhpur’s HAP is helping to advance development of several strategies to improve adaptive capacity. Because so many local residents need relief from heat, the city has prioritized public cooling stations that can help to keep urban poor and marginalized communities safer. In April 2024, MHT and JNNN introduced a first-of-its-kind Net-Zero Cooling Station. This cooling station was installed in a heat-vulnerable ward in Jodhpur North identified through the HAP’s vulnerability assessment and includes several unique features:
- It integrates a mist sprinkler fan and cooling curtains for effective reduction in temperature
- Solar panels that power lights, fans, and sprinklers, making the station more eco-friendly and sustainable
- Wind tower that utilizes natural airflow to expel hot air and usher in cooler air
- Provision of drinking water, ORS and first-aid kit facilities for enhanced comfort during heat waves
- Sitting area with benches to accommodate at least 40 people at a time
- Transparent façade for safety and visual connection with the surroundings
- Innovative Bison and Khas panels to ensure sturdiness and durability
