New Delhi banned half the Indian capital's private cars from its roads on November 4, 2019 as the megacity's 20 million people spluttered with stinging eyes in the worst pollution in three years.
As smog levels exceeded those of Beijing by more than three times, authorities also parked a van with an air purifier near the Taj Mahal—the iconic 17th-century marble mausoleum 250 kilometres south of Delhi—in a bid to clean the air in its surrounds, the Press Trust of India reported.
The measure was take for the benefit of tourists, Indian and international, who throng to get a glimpse of one of the seven wonders of the world. The air purifiers have been stationed for a 10-day trial.
If air pollution continues to rise at this alarming rate, reports are stating that the Taj Mahal will need nine years of mud packing to reduce the stains and damage caused.
With the pollution causing a rush of respiratory complaints at hospitals and the diversion of 37 flights on November 3, 2019, a new law came into effect restricting cars from the capital's roads to alternative days, depending on if their number plate ends in an odd or even number.
More than 600 police teams were deployed at road intersections in the capital with the power to hand out fines of Rs 4,000 to transgressors.
Exempt from the restrictions were Delhi's seven million motorbikes and scooters, public transport and cars carrying only women, stoking criticism that the measures were ineffective.
“There is smoke everywhere and people, including youngsters, kids, elderly are finding it difficult to breathe,” Delhi's chief minister Arvind Kejriwal said in a Twitter video. “Eyes are burning. Pollution is that bad.”
As Delhiites woke up, levels of particulates measuring less than 2.5 microns—so tiny they enter deep into the respiratory tract—were at 613 micrograms per cubic metre of air, according to the US embassy in Delhi.
Deadly over long term
The World Health Organisation's recommended safe daily maximum is a reading of 25.
In central Delhi, the state air quality institute rated levels of the tiny particulates—which can be deadly over the long term—as “severe”.
Bollywood megastar Priyanka Chopra Jonas posted a selfie in pollution mask on Instagram and said it was “hard to shoot” in Delhi.
“I can't even imagine what it must be like to live here under these conditions. We r blessed with air purifiers and masks. Pray for the homeless,” she posted.
Fourteen Indian cities including the capital are among the world's top 15 most polluted cities, according to the World Health Organization.
One study last year said that a million Indians died prematurely every year as a result.
With a state election due in Delhi in early 2020, the crisis has also become a casualty of political bickering, with each side blaming the other.
Kejriwal, who likened Delhi to a “gas chamber”, said the city had done its part to curb pollution and that the burning of wheat stubble residue on farms outside the capital had to be stopped.
Car rule 'a stunt'
But national environment minister Prakash Javadekar accused Kejriwal of politicising the issue, while an MP from the governing Bharatiya Janata Party (BJP) dismissed the odd-even car rule as a “stunt” and said he planned to ignore it.
Experts warned that both state and national governments needed to go beyond short-term remedies.
Stop-gap solutions “can't be a substitute for addressing the major long-term chronic sources of air pollution”, Daniel Cass, from global non-profit Vital Strategies, told AFP.
Changing agricultural practices, switching electricity generation sources and accelerating the conversion of home heating from charcoal to natural gas were also key measures in the pollution fight, Cass said.
Siddharth Singh, climate policy expert, said the traffic restrictions are "ineffective". "If air pollution was solely due to the vehicular traffic, then this would be a solution. Right now it cannot be a solution because motorised private transport has a very small share in the whole pie," he said.
