Urban heat islands are causing a rise in temperatures in cities across India, according to scientists. These heat islands are areas where the temperature is significantly higher than its surrounding rural areas due to human activities and development. The phenomenon is a result of factors such as the concentration of concrete structures, asphalt roads, and lack of green spaces in urban areas. Dr. Rajesh Kumar, a scientist at the National Environmental Engineering Research Institute (NEERI) in Nagpur, highlighted the impact of urban heat islands on the environment and public health. He emphasized the need for sustainable urban planning and the implementation of measures to mitigate the effects of heat islands. The rise in temperatures in cities can lead to various health issues, including heat strokes and dehydration, particularly affecting vulnerable populations. Dr. Kumar suggested strategies such as increasing green cover, promoting rooftop gardens, and using cool roofing materials to combat the urban heat island effect. It is crucial for policymakers and city planners to address this issue to create healthier and more sustainable urban environments in India. By raising awareness about urban heat islands and implementing effective solutions, cities can work towards reducing the impact of rising temperatures on the population and the environment.
