Whats the Difference Between Air Quality and Air Quality Index?

Thinking Air Purifiers Will Solve Air Pollution Problem is Disingenuous and a Waste of Important Resources

There are many ideas to improve air quality. Some of them have been tossed around for a couple of decades now. An action plan the Central Pollution Control Board (CPCB) published in 1997 found its way after 20 years into the hands of the Delhi government.

These are not overnight solutions. They include improving infrastructure, urban transport and solid waste management. As a result, it requires patience, long-term planning, interdepartmental cooperation and, most importantly, joint action by all political parties, since the implementation and outcomes can have a considerable time lag. All straightforward – but not simple to pull off.

This is why technological gimmicks that promise overnight improvements without any reduction in emissions, systemic policy changes or infrastructural improvement are bound to be disingenuous, and a waste of important resources. And this is exactly what the multiple proposals to install air purifiers at intersections to reduce ambient air pollution are.

We cannot improve air pollution by sucking pollutants out of the atmosphere. The only way to control pollution is by controlling pollutants entering the atmosphere – i.e. by controlling emissions.

The Three Kinds of People We Need to Fight India’s Air Pollution Problem (the WIRE)

I recently re-read the book Tipping Point by Malcolm Gladwell. I enjoyed reading it in 2003-04 and enjoyed going through it again, the long explanations, stories in stories, and how simple concepts led to big changes in various fields.

One recurring theme in the book is about the three agents of change: (a) connectors – network of likeminded people; (b) mavens – information specialists; and (c) salesmen – persuaders. This got me thinking about parallels in the world of air pollution. I see myself as an atmospheric scientist, but where is my place in the field of air quality management? Similarly, what is the role of likeminded people in this space, who are trying to push for a change – moving from dirty air to clean blue skies?

Following the same three-agents principle, I see three interlinking groups working in the field of air pollution: (a) Feeders (b) Drummers and (c) Changers. Read the full article @ the WIRE

Poster - Lower Emissions Lead to Lower Concentrations

inspired by Einstein's relativity equation

We said this before and saying it again - if the goal is better air quality, then we have to target the emissions at the source.
