City: Chennai

A collective of active citizens, non-governmental organisations, sustainable transport experts, and other stakeholders has called for strengthening the public transport network in Tamil Nadu's cities, making it accessible to all and creating low-emission zones across urban centres. The Sustainable Mobility Network (SMN), a coalition of over 30 civil society organisations across India, has released the 'Tamil Nadu Urban Mobility Charter 2031', a comprehensive roadmap urging political parties and governments to put sustainable mobility at the heart of the state’s development agenda. The Charter was shaped through a multi-stakeholder roundtable convened by ITDP India, Citizen consumer and civic Action Group (CAG),…

Street vending represents a unique form of business in which the vendor's day begins and ends on the street. Vendors typically toil from dawn until late at night, often for 12 to 14 hours a day, yet many continue to remain economically vulnerable. Poor economic conditions prevailing between 1980 and 2010 forced a large number of individuals to drop out of school, compelling them to take up street vending of various goods as a means of survival. Today, India is home to nearly 10 million street vendors, accounting for about 15 per cent of urban informal employment. Recognising their contribution…

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…
