Farmers, drivers and street food sellers in Guwahati are the occupations most vulnerable to climate change impacts in the northeastern city, while doctors are the least vulnerable, found a study that blends society and science for clues that can aid urban planning. Global climatic models and climatic predictions fail to explain the impacts on a very small scale, challenging planners and decision-makers in providing location- and ecology-specific solutions. Plugging this gap by incorporating people’s voices – like this study by IIT-Guwahati has done – is especially necessary for cities like Guwahati that have rapidly and silently expanded, barging into eco-sensitive…

As rapidly-expanding Guwahati, northeast India’s largest metropolis, gears up to clean its air under the National Clean Air Policy (NCAP), a study suggests a cocktail of natural and man-made pollutants wafting through the air is tinkering with the city’s rainwater quality. Guwahati in Assam is among the 122 ‘non-attainment’ cities identified for implementing mitigation actions under the national policy, which means it does not meet the National Ambient Air Quality Standards. Researchers said pinpointing critical sources of air pollution and their contributions to the problem are essential to crafting effective city and region-specific air pollution control plans. Connecting the dots between the origin of…

In India’s IT capital Bengaluru, sprinkled within its concrete jungle, are shady peepal trees adorned with serpent stones, bells and sacred threads, standing majestically atop gated, raised platforms. Often a pit-stop for tired travellers or an informal gathering place, these culturally-important open-air tree shrines or ‘kattes’ and temples, with their assemblage of native tree species, offer immense scope to enhance the green infrastructure within rapidly growing megacities, suggests a study. Offering a glimpse into the city’s native trees, the study documents 121 such species thriving in 69 sacred sites in Bengaluru, spread across 36 temples and 33 kattes, a sizeable…

In the ongoing Amsterdam Light Festival, illuminating the city’s waterway, a Serbian artist duo’s installation of an LED version of Vincent Van Gogh’s iconic painting ‘The Starry Night’ has drawn attention to the growing menace of light pollution in urban areas. 7000 kilometres away, in India’s commercial capital Mumbai, Nilesh Desai is steadily working on a public interest litigation on light pollution-disturbance due to excessive, inappropriate and misdirected artificial lights. For the last couple of years, Desai, who holds a day job in the information technology sector, has been fighting against the excessive and obtrusive glare of floodlights in his neighbourhood. He has fired…

If you have a maxed out your credit card, you may be scrambling to pay your outstanding bills. India’s technology hub, Bengaluru, with its dying lakes and mushrooming urban growth, is facing a similar situation – it has overexploited its groundwater and is now struggling to keep up with the demand, according to an expert. “We are using groundwater like an overdrawn credit card and we don’t have the capacity to repay,” said Samrat Basak of World Resources Institute India (WRI India) expanding on an analysis by the global research organisation. The WRI India analysis, accessed by Mongabay-India, notes that…
