India, Pakistan, Nigeria and Ghana together host the largest number of cities at risk of extreme heat, with major tourist destinations including Jaipur and international business hubs in the top 50, according to an analysis that has ranked 205 of the world's largest cities. More than 95 per cent of the most at-risk cities are in South and Southeast Asia and Sub-Saharan Africa. Iraq's city of Al Basrah is the world's most at-risk, followed by Ahmedabad in Gujarat, the study published in the journal Sustainable Cities and Society says, identifying places where people are most in danger as the planet continues to warm. Fourteen Indian cities that featured in the top 50 at-risk locations included Nagpur and Pune in Maharashtra, Madurai and Chennai in Tamil Nadu, Karnataka's Bengaluru and Uttar Pradesh's Kanpur and Lucknow. Lead author, Nethmi Jayaratne Kariyawasam, a researcher at the UK's Oxford University, said, "It isn't just exposure to hot temperatures that matters for risk. Our .
The government is planning to introduce the 'Golden City Club' initiative aimed at recognising cities that consistently excel in various development indicators, Union Minister Manohar Lal Khattar announced on Friday. Khattar explained that this initiative will create a special category for cities which hold top ranks in government assessments across the country. "This year, we have devised a plan where those cities that come first every time will be grouped into a separate category called the 'Golden City Club,'" the union minister said. He further elaborated that only cities securing top positions in their respective categories would be included in the club. Each year, a new city that bags the top ranks in its vertical will be added to this prestigious club. "Every year, the top-ranking city will join the Golden City Club, and there will be separate competitions for this club," Khattar explained. However, the club will not be permanent for its members. Cities that fail to mainta
Urbanization has led to nearly 60 per cent more night-time warming in over 140 prominent Indian cities compared to non-urban areas surrounding them, a new research from the Indian Institute of Technology Bhubaneswar has found. According to the research, Ahmedabad, Jaipur and Rajkot had the highest urban effect, while Delhi-NCR and Pune were found to be at the fourth and fifth position, respectively. Urbanisation is known to be responsible for the urban heat island (UHI) effect, in which the concrete and asphalt (used in constructing roads and pavements) surfaces store heat during the day and release it in the evening, thereby raising night-time temperatures. Over time, this heat further affects other aspects of climate, including rainfall and pollution, researchers said in the study published in the journal Nature Cities. The study sought to determine how much urbanisation and local climate change each contributed to raising night-time temperatures over the past two decades ...
