Urban growth may fuel heat stress in Patna, say scientists
1 2 Patna: The historic city of Patna, which has experienced rapid urbanisation over the past few decades, is likely to face more extreme heat and fewer cold days in the coming years, according to a new study published in the 'International Journal of Theoretical and Applied Climatology'. The research, led by Pradhan Parth Sarthi, head of the environmental science department at the Central University of South Bihar, highlighted the increasing climatic challenges facing Patna, a city also undergoing development as part of the Smart Cities Mission. These challenges include the formation of urban heat islands and more frequent flooding, both linked to extreme weather events. The study projected that between 2030 and 2065, under the current global warming scenario, Patna will experience a significant rise in the number of days with temperatures exceeding 40°C. It also forecast a considerable increase in the percentage of days when the daily maximum temperature will be above normal. Conversely, the number of colder days – with minimum temperatures below 10°C – is expected to decline. "Such changes in extreme temperature indices may have a major impact on the urban climate," the study said. It warned of potential consequences for public health, including an increase in heat-related illnesses such as heat stress and exhaustion. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Kardioloog: Buikvet na je 50e?

Situated in the densely populated Gangetic plains, which are home to 40% of India's population, Patna exemplifies unchecked urban expansion. "Most of the city's high-rises lack green spaces or green rooftops, in clear violation of environmental norms," the study said. In response to such issues, the Smart Cities Mission was launched by the Prime Minister on June 25, 2015, aiming to promote urban areas that offer core infrastructure, a clean and sustainable environment and an improved quality of life through smart solutions. Co-investigator Prabhat Kumar said the findings could inform sustainable urban planning for Patna. "We have conducted similar analyses for Delhi, Lucknow, Prayagraj and Varanasi," he added.

Patna likely to see more hotter days & less colder days by 2030: Study
Patna: The historic city of Patna, which has witnessed very fast urbanisation in the past few decades, is likely to face extreme weather conditions with more "hotter" days and less "colder" days in future, according to a recent study published in 'International journal of Theoretical and Applied Climatology'. Tired of too many ads? go ad free now A team of scientists, headed by Central University of South Bihar's environmental science department head Pradhan Parth Sarthi, has found that as per the current status of urbanisation, Patna — which is also being developed as a smart city — is facing several climatic challenges, including urban heat islands and flooding, caused by extreme weather conditions. The study indicates that in future, during the period of 2030-65, under the existing global warming scenario, the city may get a significant increasing trend in number of days with temperatures greater than 40°C and also a considerable increase in the percentage of days with the daily maximum temperature above normal. Similarly, there could be a deceasing trend in the number of days with a minimum temperature less than 10°C. Such possible changes in extreme temperature indices may have a significant impact on urban climate. Furthermore, it could also impact public health by increasing the incidence of heat-related illnesses such as heat stress or exhaustion, according to the study. The study observes that urbanisation in the past few decades has been very fast as people in large numbers have migrated from villages or small towns to Patna for a better quality of life and better economic opportunities. The Gangetic plains are home to 40% population of India. Patna is the best example of fast urbanisation, where most of the high-rises are without green spaces and green rooftops, in complete violation of the environmental norms. To overcome these issues, the study said, the Smart Cities Mission was launched by the Prime Minister on June 25, 2015. The main objective of the mission was to promote cities that provide core infrastructure, and clean and sustainable environment, besides giving a decent quality of life to their citizens through the application of "smart solutions". The co-investigator of the study team, Prabhat Kumar, pointed out that the results of the study may be utilised for developing Patna as a smart city. They have done similar analysis for Delhi, Lucknow, Prayagraj and Varanasi, he added.
