Commuters passing through Ambattur Industrial Estate inevitably find a layer of dust coating their vehicles, faces, and hands. For Lalitha*, a domestic worker employed at a high-rise apartment near Padi flyover’s Saravana Stores, the last two weeks of December have been especially unbearable. "Dust, dust, dust everywhere," she says, coughing through a persistent cold. At 6 pm, when the rush hour begins, it takes her nearly 30 minutes by bus to cover the 5 km journey home. The ride to the Dunlop area is punctuated by pollution, blaring horns, and endless traffic snarls. “It should take 15 minutes usually, but…

As sweater weather arrives, winter brings purple December flowers, fresh Ooty carrots with slivers of roots, and crisp Kashmiri apples to Chennai’s Koyambedu Wholesale Market Complex (KWMC). Much before dawn, workers unload crates of seasonal produce, and retailers vie for the best prices at Asia’s biggest market place for perishable goods. For the last 15 years, Murugan*, a parking personnel at the flower market's gate, has witnessed the coming and going of seasons, flowers, customers, and trucks. Most of all, he has seen the cityscape change with the addition of flyovers, bridges, cars, and metro construction. This December, a combination…

For over two decades, residents along Chennai's Old Mahabalipuram Road (OMR) have been fed a steady diet of promises about piped water supply. From desalination plants to reservoirs, successive governments have announced grand projects that would finally quench the IT corridor's thirst. Yet, as of January 2026, OMR residents are still struggling with inadequate piped water and are forced to rely on expensive private tankers or depleted groundwater that grows more brackish each year. The original promise It began with hope. In July 2004, the then Finance Minister, P Chidambaram, announced central government support for a desalination plant near Chennai.…

In 2014, Srividhya didn’t imagine she would help dozens navigate through mental illness, consistently pushing them to reflect and dream of a better life. The 55-year-old’s routine involves shuttling between ten homes for the mentally ill run by The Banyan, a Chennai-based NGO, across Kovalam. A long list of daily tasks ensues — attending to the mental health needs of service users, supervising hygiene, functioning, and vital signs, and noting medications, as well as participating in group discussions, among others. “When clients say they are glad I’m coming, it feels like a certification beyond money, pride and fame. It feels…

Chennai’s unregulated urbanisation has destroyed its water bodies and disrupted its natural drainage systems. This is true for the Kodungaiyur Canal System in North Chennai which includes the Ambattur, Korattur and Retteri lakes. This crucial waterway is designed to drain floodwaters into the Ennore Creek but is marred by encroachments and illegal sewage discharge. In fact, Kodungaiyur Lake, a part of Kosasthalaiyar and Cooum basin, is one of the lakes that has been eaten up and has been reduced to narrow canals because of human activity and government negligence. Flooding in encroached area, vulnerable groups affected During a datajam organised…

When the northeast monsoon hits Chennai, a foreseeable result of the heavy downpour is severe flooding in several areas, including Porur Lake. As residents living near this 200-acre water body battle inundation every year, our team set out to investigate the root causes of flooding using available data. Environmental issues have often been dealt with a one-size-fits-all approach, but our study aimed to provide specific solutions tailored to the Porur catchment area. For this, we mapped inundation patterns, land gradient, land use change and the outlay of stormwater drains (SWDs).   At a recent datajam organised by the Oorvani Foundation…

In 2015, when her infant daughter began wheezing, Subashini R purchased a machine she had only ever seen in hospitals. Daily trips from Kattukuppam in north Chennai to Tondiarpet Hospital were expensive, costing at least ₹500 then. Although the nebuliser cost four times her daily healthcare expenses, it reduced long-term costs in a region struggling with the lasting effects of pollution. “Every doctor tells locals to leave the region due to the chemicals here,” says the activist, part of the Save Ennore Creek Campaign. A decade later, nearly every household in Ennore has a nebuliser. Her younger daughter now suffers…

The Cooum River, once a sacred river that shaped the history of Madras, has now become a sad sign of urban degradation. For the millions of residents in Chennai, it has transformed into a malodorous, polluted, and stagnant channel, burdened with solid waste accumulation and extensive encroachments along its banks. During a recent datajam organised by Oorvani Foundation and OpenCity, we used Geographical Information System (GIS) datasets and population analytics to investigate the underlying causes contributing to this crisis. The results show that rapid urbanisation, inadequate provision of essential civic infrastructure, and the absence of coherent policy frameworks, along with…

Fifty-five-year-old Gnana Bharathi, a scientist at the Central Leather Research Institute and a wheelchair user for over two decades, rarely takes the bus anymore. Chennai’s bus stops and termini, he says, are designed in a way that makes independent travel “nearly impossible”— from reaching the stop safely, to getting onto the platform and finally boarding the bus — without physical risk. So, when the Greater Chennai Corporation declared the Vivekananda House Bus Stop on Kamarajar Salai as an accessible, ‘model bus stop’, he decided to try it.“When I arrived at the location in my wheelchair, I couldn’t even access the…
