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).

PM Modi pays tribute to Atal Bihari Vajpayee at Sadaiv Atal, says leadership is defined by conduct

Prime Minister Narendra Modi on Thursday paid floral tributes to former Prime Minister Atal Bihari Vajpayee at the ‘Sadaiv Atal’ memorial in New Delhi on the occasion of his 101st birth anniversary. Remembering Vajpayee’s legacy, the Prime Minister said that true leadership is not established by position, but by conduct.

Several dignitaries were present at the memorial to pay homage to the former Prime Minister, who remains one of the most respected figures in Indian politics.

PM Modi remembers Vajpayee’s conduct and values

In a message shared on social media platform X, Prime Minister Modi described Atal Bihari Vajpayee as a statesman whose behaviour, dignity and unwavering commitment to national interest set a benchmark for Indian politics. He said Vajpayee’s life continues to inspire the nation and highlights that leadership is determined by character rather than authority.

The Prime Minister also shared a Sanskrit verse, noting that the actions of great leaders guide society, and said this principle was clearly reflected throughout Vajpayee’s public life.

‘Nation always came first for Atal ji’

Prime Minister Modi further said that Vajpayee’s birth anniversary is an opportunity for everyone to draw inspiration from his life. He highlighted Vajpayee’s conduct, grace, ideological firmness and resolve to place the nation’s interest above all else as an ideal standard for public life.

Through his life and work, Vajpayee demonstrated that excellence and greatness are shaped by values and conduct, not merely by holding office, the Prime Minister said. The remarks were shared with inputs from media.

Cried over Gaza, not a word on Bangladesh: Yogi Adityanath attacks opposition in UP Assembly

Yogi Adityanath criticised the opposition in the UP Assembly, accusing them of selective outrage over Gaza while remaining silent on violence against Hindus in Bangladesh.

Yogi Adityanath

Uttar Pradesh Chief Minister Yogi Adityanath on Wednesday launched a sharp attack on the Opposition during proceedings in the State Assembly, accusing rival parties of indulging in selective outrage and appeasement politics while remaining silent on incidents involving Hindus in neighbouring countries, particularly Bangladesh.

Referring to recent incidents across the border, the Chief Minister said the Opposition raises its voice on international issues selectively but avoids speaking out when minorities, especially Hindus, are targeted in nearby nations.

“You shed tears over developments in Gaza, but not a single word comes out when a Dalit youth is killed in Bangladesh,” Adityanath said in the Assembly, alleging that such silence exposes the Opposition’s political priorities.

The Chief Minister further claimed that incidents of violence against Hindus would not have occurred had Pakistan and Bangladesh not been created, reiterating that issues are often viewed through the prism of vote bank politics. He said candle marches are organised for global events, but killings of Hindus in Pakistan or Bangladesh do not evoke similar responses.

Adityanath also called for a condemnation resolution in the Assembly, stating that it should ideally come from the Leader of the Opposition. He said such a resolution should clearly condemn the killing and convey a warning to the Bangladesh government.

Allegations over illegal immigration

Targeting the Opposition on the issue of illegal immigration, the Chief Minister alleged that they support Bangladeshi nationals and Rohingyas. He claimed that when authorities take action to expel illegal immigrants, Opposition leaders come out in their defence, alleging that many of them have been facilitated with voter registrations and Aadhaar cards.

Meanwhile, tensions between India and Bangladesh have been visible following recent developments. India summoned the Bangladesh High Commissioner for the second time in a week amid concerns arising from incidents in the neighbouring country.

The summons came in the backdrop of protests in Bangladesh following the killing of student leader Sharif Osman Hadi and the lynching of Dipu Chandra Das in separate incidents. Dipu Das, a 27-year-old youth from Mymensingh district, was beaten to death by a mob over alleged blasphemy on December 18, and his body was later set on fire, triggering widespread outrage.

The Interim Government of Bangladesh condemned the incident. Education Adviser C R Abrar visited the bereaved family on behalf of the government, expressed condolences, and assured them of financial and welfare assistance. The Office of the Chief Adviser also reiterated its resolve to protect all citizens and ensure justice in the case.

The killing has once again raised concerns at the international level over the safety and security of minorities in Bangladesh, with minority groups demanding strict action against those responsible.
