This article is part of a special series: Air Quality in our Cities If you were to go walking in Nagavarpalya area in the city, and take the inner by-lanes ahead of Gopalan Mall, you would come upon a sprawling settlement, home primarily to migrant workers from Northern Karnataka. They stay in small makeshift structures that are covered with blue tarpaulin sheets. Such settlements are present in several parts of the city, and they are usually devoid of basic facilities of sanitation, adequate supply of water, electricity etc. "If the migrant workers are staying with their families, they usually cook inside…

"Celebrating four years of changemaking"- this is what my good friends at Namma Ooru Foundation (NOF) Called the event. So naturally I expected to hear stories of the journey, milestones, troubles encountered along, successes hard earned, etc. And of course I knew that I would be meeting many of Chennai's environment warriors. I was looking forward to it. It was all that, and more. I met several of the remarkable individuals that we keep reaching out to, both for our writings at Citizen Matters, and in our personal capacity, for guidance in our efforts to refuse, reduce, reuse and recycle.…

Reports about a third desalination plant, with a capacity of 550 million litres a day (MLD), have raised hopes among Chennaites. Convinced that their water woes can be successfully addressed with advanced technology, citizens welcome the state government’s proposal of the plant that would make sea water potable. But, are desalination plants really the solution we need? Environmentalists are often deeply critical of pollution caused by desalination plants. But, even if we put aside the concerns around environmental damage  for the present discussion, desalination plants themselves do not appear to be economically viable for the city. An extravagant affair The…

Translated by Sandhya Raju தற்போது நிலவி வரும் தண்ணீர் பிரச்சனைக்கும் ஏரிகள் சுரண்டப்பட்டதிற்கும் சம்மந்தம் இல்லாமல் இல்லை. நிலத்தடி நீரின் அளவை உயர்த்த உதவும் இந்த ஏரிகளை மக்களும் அதிகாரிகளும் முறையாக பராமரித்து இருந்தால், தண்ணீர் தட்டுப்பாட்டை சந்திக்கும் நிலை உருவாகியிருக்காது என்பதே நிதர்சன உண்மை. நகராட்சி எல்லைக்குள் இருக்கும் பல்லாவரம் பெரிய ஏரி மற்றும் கீழ்கட்டளை ஏரிகளின் நிலை என்ன என்று பார்ப்போம். நட்டேரி, அன்னேரி, ஜதேரி என இங்கிருக்கும் பல ஏரிகள் குடியிருப்பு பகுதியாக மாறிய நிலையில், பல்லாவரம் பெரிய ஏரி, கீழ்கட்டளை ஏரி போன்ற சில ஏரிகள் மட்டுமே இன்று இருக்கின்றன. இந்த ஏரிகளும் பரிதாபகரமான அழிவு நிலையில் தான் உள்ளன. வணிக ரீதியாக முன்னேறி இருக்கும் பகுதியில் ஐந்து கிலோமீட்டர் தொலைவில் இருக்கும் இந்த இரண்டு ஏரிகளும் சந்திக்கும் சவால்கள் ஒன்று தான்: குறைந்து போன நிலத்தடி நீர் மற்றும் கழிவு நீர் குப்பைகளால்…

The scenic Pallikaranai Main Road with patches of greenery and occasional glimpses of migratory birds in winter would have been a treat for the passer by, but for the unbearable stench. The smell of rotten biodegradable waste and  noxious fumes from burning of plastic waste assail your senses every time you hit the road. A few metres from the marshland, a Chennai Corporation maintained earth mover dumps the mixed waste on to it. The wetlands of Pallikaranai were brought under the reserved region by the state government 10 years ago and are now under the jurisdiction of the forest department.…

There is a spot on the lake land where one gets a 180 degree view of the sprawling 445 acre Varthur lake. The lake is filled with water and emits a strong foul odour. The southern end of the lake is filled with snowy froth. A wire mesh is erected along a section of the road near the lake to prevent the froth from entering the road. "Till the 90s, several migratory birds from Russia, Ukraine, China used to visit Varthur Lake, which acted as food source for them before they headed to the Southern Hemisphere. Once the sewage started…

The plastic ban that has been in the news since its implementation on January 1, is now losing steam in Tamil Nadu. Retailers and vendors across the city have been using plastic secretly, in fear of losing regular customers. Several bars maintained by the state government (TASMAC) are openly allowing plastic. “If I don’t give out a plastic cover, customers don’t buy flowers. Who would spend Rs 3 on a cloth bag for wrapping up flowers worth Rs 10 or Rs 15?” asks Vanavani, a flower vendor at Mambalam market. There is little awareness about the ban in rural parts…
