…from its toxic air?
by Meera Subramanian
In A River Runs Again, I explored the devastating effects of cook fires on human and climatic health, but they are just one part of what is causing New Delhi to claim the worst air quality of any major city in the world. Since January, I’ve been researching what it is that makes Delhi’s air so toxic and what steps the city is undertaking to try to improve it. Here’s the start of the piece just published in Nature:
On winter nights, New Delhi burns with innumerable fires. Flames flicker along pavements and street corners, where the destitute huddle to stay warm and cook their suppers, while night watchmen stand guard next to their own small blazes outside private homes.

But a move for more buses, and more pedestrian crossways, and to actually make parking on a footpath an offense, is an excellent start. Increased attention to the issue is a hopeful indicator of more action to come.
If you want to know more, nonprofits such as the Centre for Science and the Environment and Care For Air both are work to inform the public about the city’s air quality, UrbanEmissions brings together concise graphics and scientific information to help understand a complicated issue, and the Air Quality in Delhi Facebook group connects concerned citizens.
I also wrote a couple of pieces specifically about the odd-even traffic reduction plan that was underway when I was in Delhi in January. “New Delhi car ban yields trove of pollution data” was in Nature and the piece with the (mildly overblown!) title “Amazing Things Happened When New Delhi Halved the Number of Cars on the Road” ran in Vice News.
Measuring air quality is incredibly tricky business. The 122 micrograms per cubic metre [Read more…]
