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).

West Bengal government to launch Annapurna scheme from June 1, offering monthly aid of Rs 3,000 to women

The West Bengal government has announced the Annapurna Yojana, providing Rs 3,000 monthly financial assistance to eligible women aged 25–60 starting June 1, 2026. Existing beneficiaries of the older scheme will be automatically migrated subject to verification.

The West Bengal government has officially notified the rollout of the ‘Annapurna Yojana,’ a welfare initiative aimed at providing assured monthly financial assistance of Rs 3,000 to women across the state. Introduced by the Department of Women and Child Development and Social Welfare, the scheme is structured to foster the socio-economic upliftment of women and will officially come into effect on June 1, 2026.

Under this new initiative, financial benefits will be transferred directly into the Aadhaar-linked bank accounts of qualified beneficiaries using the Direct Benefit Transfer (DBT) system.

Strict eligibility criteria outlined

According to the official government notification, specific guidelines have been established to determine eligibility for the monthly cash assistance:

  • Target Age Group: Eligible women must be between 25 and 60 years of age.
  • Employment Status: Applicants must not hold permanent government employment or receive a regular salary or pension from the central government, state government, statutory bodies, panchayats, municipalities, local bodies, or government-aided educational institutions.
  • Tax Criteria: Women who are income tax payers are excluded from the scheme.

Automatic migration and scrutiny rules

The new order clarifies that all current beneficiaries of the erstwhile Lakshmir Bhandar Scheme will be automatically migrated to the Annapurna Yojana. However, the transition involves a rigorous filtering process. Individuals identified as deceased, shifted, deleted, or recorded as absentee electors during the SIR-2026 exercise or voter slip distribution will be systematically excluded from the beneficiary list.

On the other hand, individuals who have filed appeals before the SIR Tribunal or submitted applications under the Citizenship (Amendment) Act will continue to receive financial assistance until their applications are legally resolved by authorities.

Application process for new beneficiaries

For fresh applicants, a dedicated online portal for the Annapurna Yojana will be launched on June 1, 2026. To ensure transparency, all new applications will undergo a strict multi-tier verification process by designated local administrative officials:

  • Rural Areas: Block Development Officers (BDOs) will manage the verification and inquiries.
  • Urban Areas: Sub-Divisional Officers (SDOs) will oversee the process.
  • Kolkata: Officials of the Kolkata Municipal Corporation (KMC) will handle applications within their jurisdiction.

Following field inquiries, verified reports will be uploaded directly to the digital portal. The respective District Magistrates and the KMC Commissioner will serve as the final sanctioning authorities in their corresponding jurisdictions to approve the disbursement of funds.

Tamil Nadu Chief Minister C. Joseph Vijay travels to New Delhi for first official meeting with PM Narendra Modi

Newly sworn-in Tamil Nadu Chief Minister C. Joseph Vijay embarked on his first official visit to New Delhi to hold a high-level meeting with PM Narendra Modi, focusing on economic aid, fertilizer supply, and water rights disputes.

Tamil Nadu CM Vijay and PM Modi

Marking his maiden official visit to the national capital since assuming office, Tamil Nadu Chief Minister C. Joseph Vijay is scheduled to meet Prime Minister Narendra Modi on Wednesday to deliberate on a wide range of state-specific matters. The Tamilaga Vettri Kazhagam (TVK) chief, who led his fledgling party to a historic victory in the recent assembly elections, took the oath of office on May 10. While the Prime Minister had previously extended his congratulations via social media, this marks the first formal in-person meeting between the two leaders.

According to official sources, the Chief Minister departed from Chennai on a chartered flight at 10:00 AM. The high-profile meeting with the Prime Minister is slated for 4:30 PM, where Vijay is expected to submit a comprehensive memorandum outlining Tamil Nadu’s long-pending welfare and developmental demands.

Key state matters on the table

The core of the discussions is expected to center around financial assistance and clearances for major infrastructure projects in the state. Media reports indicate that the Chief Minister will heavily push for additional funds to bankroll ongoing developmental initiatives.

Furthermore, the interstate Mekedatu water dispute remains a high-priority issue. Chief Minister Vijay has already written to the Prime Minister, urging him to instruct the Union Jal Shakti Ministry and the Central Water Commission (CWC) to reject the Detailed Project Report submitted by Karnataka for a reservoir at Mekedatu.

Other critical administrative concerns to be raised include ensuring an uninterrupted supply of fertilizers for the upcoming Kharif farming season and the removal of the 11 percent import duty on cotton to protect the raw material supply chain for the state’s textile industry.

A packed diplomatic itinerary

Accompanied by a team of senior officials and select cabinet colleagues, the Chief Minister’s itinerary extends beyond the Prime Minister’s Office. Vijay is likely to sit down with Union Finance Minister Nirmala Sitharaman to directly advocate for financial backings for key state portfolios.

The new administration has also drawn national interest for its structural innovations, including retaining critical departments under the Chief Minister—such as Home, Police, and Women Welfare—and carving out a dedicated cabinet-level Artificial Intelligence department, making Tamil Nadu only the second state in the country to do so.

Navigating a complex political landscape, the TVK-led government, which holds 108 seats in the assembly and enjoys backing from coalition partners including the Congress, Left parties, VCK, and IUML, is also using this trip to engage with national opposition leaders. Chief Minister Vijay is scheduled to meet Congress leaders Sonia Gandhi and Rahul Gandhi during his stay in the capital.

Before wrapping up his tour, the Chief Minister is slated to participate in a cultural event at Jawaharlal Nehru University (JNU), where he will formally inaugurate a statue of the revered Tamil poet-saint Thiruvalluvar installed by the Tamil Nadu government. Sources indicate that Vijay will conclude his official engagements and return to Chennai on Thursday.

The Assam Legislative Assembly on Wednesday passed ‘The Uniform Civil Code, Assam, 2026 Bill’, making it the third state ruled by the Bharatiya Janata Party (BJP) to adopt a uniform legal framework after Uttarakhand and Gujarat.

Opposition flags concerns over rights during house debate

The bill was taken up for final passage in the state assembly on Wednesday, sparking a heated discussion among lawmakers. During the legislative floor debate, opposition MLAs strongly voiced their concerns regarding the proposed law, stating that the legislation will hurt and compromise the fundamental rights of a certain section of society.

Despite objections from the opposition benches, the treasury benches cleared the passage of the bill, cementing Assam’s position as the latest state to move away from diverse personal laws in favor of a uniform code. Media reported that the legislative move follows extensive political discussions in the state surrounding civil regulations. With this enactment, Assam joins Uttarakhand and Gujarat, which have previously passed their respective uniform civil codes.
