On September 4th, Bengaluru experienced one of its wettest days on record, causing large parts of the city to get severely flooded. This was after weeks of heavy rainfall that turned roads into rivers in some of the city’s rapidly developing ‘high-tech’ areas. This is going to happen again and again unless we fundamentally change how we approach urban planning. We need to proactively work with the assumption that such severe extreme weather events are the new normal and what can be done to prevent flooding in the city under these circumstances. As a sustainable architect and environmental modeller, I…

Over the years, the water bodies in Chennai and across the state have been polluted and damaged due to many reasons including rapid urbanisation and encroachments. Time and again, the restoration work being carried out in these water bodies make it to the news. Often, the local bodies rope in Non-Governmental Organisations to oversee or carry out either the entire or some portions of the restoration work. This apart, many private companies also chip in with Corporate Social Responsibility (CSR) funds to carry out restoration work. While the restoration work is carried out by different agencies at different places, there…

Mumbai city celebrated Ganesh Chaturthi with great splendour after almost two years of low-key celebrations. During COVID lockdowns, social distancing meant the absence of large gatherings, even on festival days. This year’s vigorous celebrations included banjos, metal cylinders beaten with metal hammers and loudspeakers during processions for Ganesh Visarjan in Sarvajanik pandals of the city. These instruments inevitably raised noise levels. It became a cause for concern for all Mumbai residents as they grappled with the health impacts of noise. In 2016, the Bombay High Court passed a comprehensive Judgement and Order to enforce the Noise Pollution Rules. The Court also monitored the implementation…

"The house feels like a furnace during summers. We live in a very congested space which makes it difficult to sit inside the house and even more difficult for me to cook due to the heat. I get headaches and my kids experience skin problems too," says Guna, a resident of Jyothipura, an urban poor settlement in Bengaluru. Heat stress is not a new concept given the realities of rising local temperatures in India. But Guna’s plight, faced by every family living in tin-roofed houses in informal settlements, reflects the inequitable realities of heat stress in urban India. Houses of…

Mr G R Alfred Rupak, correspondent of St. Antony’s Matriculation Higher Secondary School, Thiruvottiyur says it started on July 5th, when a pungent odour akin to LPG gas permeated the air, forcing students to exit their classrooms. The malodour also affected other residents of Thiruvottiyur and Manali, with many reporting breathlessness and eye irritation. The stench, they feared, was a sulphur dioxide leak from the Chennai Petroleum Corporation Limited (CPCL) which operates a refinery in Manali. TNPCB addresses gas leak in North Chennai The Tamil Nadu Pollution Control Board (TNPCB) issued orders at once for CPCL to monitor ambient air quality;…

Floods in Bengaluru make for big headlines. The plight of monkeys rarely does. In this case, the particular species named Bonnet Macaques, which can usually be seen in the vicinity of the city's temples. As the city's urban sprawl spreads inexorably, natural habitats of many species are getting overrun. Monkey habitats are one such. Causing what some Bengalureans call the monkey menace. Meaning when they spot a monkey sitting outside their apartment's kitchen window in search of food. A Scroll report, citing the work of Mewa Singh of the University of Mysore and HN Kumara of Salim Ali Centre for…

On 30th August, a resident of Rainbow Drive, a layout on Sarjapur Road, passed away as he could not get to a hospital in time. His community had been flooded and its residents marooned for hours during which even tractors could not reach them. On 5th September after the heavy overnight rains of up to 90 mm, residents of this area and the larger Sarjapur Road-Outer Ring Road area continue to suffer, with large sections of even main roads inundated. Rainbow Drive is one of the parts of the city that has had far too many trysts with flooding. Even…

""Kitne aadmi the?" The scene featuring Gabbar Singh's famous question in Sholay has a rarely noticed sideshow. A small lizard scampering across the rocky terrain of Ramanagara, located just outside Bengaluru, where the iconic movie was filmed. That lizard is the Peninsular Rock Agama, or Psammophilus dorsalis, which can be found today mainly in Bengaluru's rocky outskirts. The city's ever expanding urbanisation has not only altered natural landscapes in its wake, but also destroyed habitats of species like the Rock Agama lizard. And although not endangered, the Peninsular Rock Agama is no longer a common sight across the city as…

The movement to save Aarey forest - known as Mumbai's green lungs - from construction activities has awakened again. Every Sunday the area is packed with protestors sloganeering, holding placards, and shouting anthems of resistance. What best encapsulates the sentiment on the ground are the first two lines of the song 'Aarey chi Kalji', which went viral recently: "Sarkar yeil sarkar jaail jhaad tu todu nako, ugaach kamal gheoon haataat Aarey la chedu nako" (Governments will come and go, do not cut our trees. Holding a lotus in your hand, do not play with our Aarey.) Writing on the wall near the road…

Pallikaranai marshland has become the first wetland in Chennai to get the Ramsar tag in July 2022. The award of the Ramsar tag is part of UNESCO's Ramsar Convention, which is an intergovernmental treaty aimed to conserve wetlands. India has been a party to the treaty since 1982. While this is welcome news, Pallikaranai has also seen a lot of damage over the years, despite being a "protected zone" as per the Tamil Nadu Forest Act. From 2,650 hectares, the wetland has shrunk to around 700 hectares, thanks to encroachments by government and private entities, garbage dumping, leakage of untreated…
