Smog Towers To Improve Air Quality: How Delhi Is Fighting Pollution

This year, once again, Delhi is rolling out emergency measures such as reducing road traffic, banning farm fires, and activating the city's smog towers to improve air quality.

Every winter for at least a decade now, Delhi has been bracing for extreme air pollution that harms the health of its population, particularly children and the elderly.

When temperatures drop and wind speed declines, toxic particles from car tailpipes, industrial chimneys, and construction sites remain trapped over Delhi and its satellite cities. This is also the season when farmers in neighbouring states harvest summer crops and burn the residue, leaving Delhi in a thick white haze that lasts for days.

This year, once again, the city's authorities are rolling out emergency measures such as reducing road traffic, banning farm fires, and activating the city's smog towers to improve air quality. Along with that is the revival of a debate about the effectiveness of the towers.
