From Kuruvimedu to Besant Avenue, how Chennai breathes unequally

Ahead of the art exhibition ‘Pugai Padam’, this photo essay captures the contrasting realities of air and the lived experiences of air pollution in Chennai.

The chimneys of the NTECL Vallur Thermal Power Station, billowing smoke, loom over Kuruvimedu in Ponneri, Thiruvallur near Chennai. Wedged between the plant and its sprawling 300-acre ash pond, the hamlet lies under a blanket of kari (coal) and sambal (ash), coating its narrow streets, colourful homes, and trees.

Kuruvimedu is hard to find on Google maps, just as its namesake bird. The main road leading to this place is flanked by factories and industrial complexes, its surface riddled with potholes that make every journey dangerous for motorists. 

Home to mangroves, networks of canals, and fields, Kuruvimedu once buzzed with economic activity and trade. “This area was green, and our livelihood was making salt from uppalam (salt pan) in this area. We earned less, but we were happy,” points out Kumari*, 61. Forty years ago, she says, their home food was cooked in chemical-free pure salt, but “now we are afraid to eat as ash covers even our food.” Kumari works at a nearby company as a cook, earning less than ₹12,000. 

A series of experiences like Kumari’s and photos from Kuruvimedu will be presented in an art exhibition titled ‘Pugai Padam’ (புகை படம்) from February 6th to 8th. Organised by the Pugai Padam Collective, the event challenges the state’s ritual reporting of air-quality indices, and focuses on the intersectional nature of environmental discrimination, say organisers. 

‘Pugai Padam’ aims to centre environmental discrimination and people’s experiences with air pollution.
How smog plates create art

“Across Chennai, the air quality varies. Often, we rely on instruments to measure air quality. But numbers often erase the bodily experiences as evidence,” says Nityanand Jayaraman, environmental activist and an organiser of the event.

In this context, to capture air and present it as art, “smog plates”—a pollution‑capturing medium created by Los Angeles artist Kim Abeles—will be presented from 14 locations at the exhibition, including north Chennai. These will show the stark differences in the quality of air across locations. Ahead of the exhibition, Citizen Matters visited two locations: Kuruvimedu and Besant Nagar to explore the lived realities of air pollution through conversations and observations.

A ghost town

With a capacity of 1500 MW, this plant provides 70% power to Tamil Nadu and the rest to Andhra Pradesh and Karnataka, among others, notes the NTECL website. In 2007, Sushilkumar Shinde, then Union Power Minister, laid the foundation stone for the project and in 2012, it began operations. But at what cost? The coal plant and fly ash have rendered this area uninhabitable, say residents. Pic: Sathish S; Archita Raghu.
Kuruvimedu school
“We used to study here, and now all the kids have left,” says Maari*, a youngster in this area. Abandoned homes and memories of a rich landscape haunt Kuruvimedu. A few years ago, at least 250 families inhabited this ooru. Now the 30 families that remain pray that they will be relocated. “There are no livelihoods or jobs or anything left here; we have petitioned officials to leave this town,” adds Krishnan, a town elder. “Most of the young people here are daily wage workers in the industries, despite having studied or having degrees,” says a resident.

A deluge of health problems, and floods

Kuruvimedu homes
Every morning, locals wake up to find their homes covered in fly ash. “Does the government know this ooru is here or not? Only during election time they come, but when they win, they don’t even look here,” Kumari says. Meanwhile, with no bus facilities or nearby hospitals, locals are forced to pay between ₹500 and ₹1000 to go to the nearest PHC in Minjur, over 8 km away. Pic: Sathish S.
Kuruvimedu residents
Kumari points to the ground, covered in ashy puddles. Six months ago, her husband died of a heart attack, which she believes was linked to dust allergies and prolonged exposure to pollution. No resident is spared—reddish rashes and infections mark their limbs. A 2017 report by Huma Lung Foundation & Community Environmental Monitoring found 19.2% of Ennore’s surveyed population showed chest X‑ray abnormalities from elevated pollution levels. Pic: Sathish S.
Kuruvimedu trees
Even leaves are not spared from ash. “If we don’t wear sandals, we get skin allergies,” says Maari. Each December, floods and stagnant water add to their woes. A bund built a few years ago worsened the flooding, and since Kuruvimedu lies on the path to the sea, water remains trapped here,” adds the resident. Pic: Sathish S.

Down south, a butterfly garden

While Kuruvimedu tells the story of air in north Chennai, another unfolds 40 km away. At Olcott Memorial High School in Besant Nagar, the songs of birds and insects fill the forested surroundings. Inside the school’s Blue Green Centre (BGC), a smog plate lies covered in dust, leaves, and twigs; unlike in Kuruvimedu, fly ash is nowhere to be seen. The BGC, a collaborative effort between the Theosophical Society, Pitchandikulam Forest (Auroville), and Asian Paints, aims to provide environmental education to students.

At the BGC, lessons revolve around the environment, and every question finds space. “Did you know leaf-cutter bees build nests in the hollow spaces of trees? Or that mynahs are called Naganavai in Tamil?” the students ask. Their chatter is endless, yet our conversation with the group of 11 keeps circling back to a certain winged burst of colour—butterflies. As part of the BGC, in May last year, these students came together to create a butterfly garden.

In this airy and green habitat, scores of butterflies thrive, says Meera*, a student. Last May, the students dug up holes, carefully placed native transplanted non-invasive and nectarine species in this area. “In Chennai, we have 160 species of butterflies, and since we have a centre of forests and a medicine garden, we have at least 110 species of butterflies here. We planted 17 host plants such as wild lemon and milkweed,” says BGC nature educator, Kumaresan Chandrabose. Pic: Sahana Charan.
The groups of children here take care of the medicinal garden and the butterfly garden. “When we finish class, we see trees full of butterflies, colour-colourah,” says *Dinesh, a student. They carry what they learn in the BGC and return home harbouring tales of pollination, migration, and the environment. For others like Lalitha*, the butterfly garden has rooted the idea that other species have names, habitats, and lives. Pic: Sahana Charan.

Green habitat, lessons on ecology

“Earlier, I knew only kuruvi (sparrow), kaaka (crow) and pura (pigeon), and now I know more,” points out Dinesh. From visits to Puducherry, Pallikaranai and Broken Bridge, the children are pulled into the world of ecology, learning to differentiate between leaves and trees. *Anu, another student, observed that toxic air has affected her sister, causing wheezing symptoms.  Pic: Sahana Charan

A question posed to the children was: In a world where we do not prioritise the environment, what will happen? “We will all have to buy oxygen and water to survive,” says Meena. Other dystopian futures include a scenario where plants, butterflies and other species cease to exist. Pic: Sahana Charan.

Keeping this future in mind, the children shared a few recommendations:

  • Reduce the number of vehicles. Switch to alternate sustainable vehicles such as cycles or walk more.
  • Reduce usage of plastics, and plant more trees. 
  • Fine factories, if emissions are above safe limits.

The exhibition is open for walk-in visitors from 4 pm to 7 pm on February 6–8 at Art Houz, Nungambakkam.

*Names changed.

Pallikaranai’s 1-km buffer zone sparks debate on housing rights, encroachment and ecology

On World Wetland Day, Chennai's Pallikaranai marsh shows how decades of state‑sanctioned encroachment leave residents and ecology at risk.

Across Pallikaranai marshland, migratory birds can be spotted, searching for forage and water. Yet the wetland they depend on has steadily depleted. As Chennai has grown in an amoeba-like manner, ebbing with the promise of ‘development,’ the marsh has borne the brunt. In the 1990s, the marsh covered 2,450 hectares, nearly 70% of its original size. Today, barely 500 hectares remain. In recent years, the marshland has often entered public discourse. In September 2025, Chennai Metropolitan Development Authority (CMDA), acting on an order from the southern bench of the National Green Tribunal, halted planning permission for development within the Pallikaranai…

Commuters, vendors bear the brunt of rising air pollution in Chennai’s Ambattur

IIT-M’s Project Kaatru finds high PM2.5 levels at Ambattur Estate, Padi flyover and Dairy Road, exposing residents to dust and pollution daily.

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…
