Areas selected for smart city development are ‘heat islands’: Study

[vc_row][vc_column][vc_column_text]~By Dinesh C Sharma

Study covered 89 of 100 areas selected for smart city projects, says temperature could be 1 to 6 degrees higher than surrounding areas in these heat islands

New Delhi: The phenomenon of urban heat islands, in which concrete and built areas in cities experience higher temperatures than surrounding rural areas, may get accentuated with rapid urbanisation. This is the conclusion of a new study of urban areas selected for development of smart cities.

The study, which covered 89 of 100 areas selected for development of smart cities, has found that agriculture and irrigation are two dominant drivers of urban heat islands or UHI in India. In addition, significant presence of atmospheric aerosols – mainly pollutants – over urban areas can influence UHI.

Moisture from irrigation canals and agriculture fields plays a key role in keeping rural areas surrounding cities much cooler than urban areas, resulting in cities becoming heat islands. In a heat island, temperature could be 1 to 6 degrees higher than surrounding areas. Remote sensing data and climate modelling were used to evaluate UHI all over the country.

When the surrounding non-urban areas have no agriculture during summer, cities are actually relatively cooler during daytime. However, if the non-urban areas are under irrigated agriculture, cities are warmer than surroundings. This means UHI effect during day time is mainly driven by agriculture and irrigation. However, in the night-time, cities are significantly warmer than surroundings in both winter and summer seasons. Night-time urban heat is mainly driven by the amount of heat stored in buildings and other impervious surfaces.

Urban areas located in highly irrigated regions – Indo-Gangetic Plain and north-west India (Haryana and Punjab) – show UHI intensity of 3 to 5 degrees. During summer season (April and May), when air temperature is at the peak, land surface temperature becomes is higher than that of the post-monsoon season in absence of agricultural operations. Moreover, amount of moisture and vegetation in non-urban areas are also limited as crops are largely harvested by the end of March and soil moisture is depleted due to high atmospheric water demands, the study said.

“While urban areas have experienced increased number of heat waves and temperature extremes in recent past, urban heat island effect driven by rapid urbanization can further worsen extreme hot conditions in cities,” pointed out Dr Vimal Mishra, a scientist at the Water and Climate Lab of Indian Institute of Technology, Gandhinagar, which did the study. The results of the study appeared in the journal Scientific Reports.

The development of smart cities will result in rapid growth in urban infrastructure and population, leading to increases in UHI intensity. “Our results can provide policy insights for development of smart cities,” Mishra said. “Considering night-time heating which could be significant during heat waves, measures such as passive cooling should be used. Building materials that absorb less heat and are sustainable can reduce the amount of heating caused by stored heat.” The presence of water bodies and vegetation in cities can also help reduce additional night-time heating in urban heat islands.

The study team included Rahul Kumar and Vimal Mishra (IIT Gandhinagar); Jonathan Buzan and Matthew Huber (Purdue University, USA); Rohini Kumar (UFZ-Helmholtz Centre for Environmental Research, Leipzig, Germany ); and Drew Shindel (Duke University, USA).

Ahead of Republic Day, Rajasthan Police seized a massive consignment of explosives from a farm in Nagaur district and arrested one person in connection with the recovery, officials said on Sunday.

Acting on specific intelligence, a police team carried out a late-night raid on Saturday in Harsaur village. During the operation, officers recovered 9,550 kilograms of ammonium nitrate stored in 187 sacks from an agricultural field, Superintendent of Police Mridul Kachhawa said.

The accused, identified as Suleman Khan, a resident of Harsaur village, was taken into custody at the spot. According to police, he has three previous criminal cases registered against him.

In addition to ammonium nitrate, police seized a significant quantity of explosive accessories. These included nine cartons of detonators, 12 cartons and 15 bundles of blue fuse wire, and 12 cartons along with five bundles of red fuse wire.

During preliminary questioning, Suleman allegedly told investigators that the explosives were being supplied to individuals involved in both legal and illegal mining activities. A case has been registered under relevant provisions of the Explosives Act, the SP said.

Officials also pointed out that ammonium nitrate has been linked to major blast incidents in the past, including an explosion reported near Delhi’s Red Fort in November 2025.

Police said central agencies have been informed about the seizure and are expected to question the accused as part of a broader investigation.
