Toxic smog turns India’s capital “into a gas chamber”

75

Authorities in India stepped up efforts on Friday to address deteriorating air quality as farmers burning crop stubble and calmer winter winds left a thick blanket of haze and smog to choke residents across the Delhi capital region. Factories, construction sites and primary schools were ordered to shut down and Delhi authorities urged people to work from home as dangerous fine particle pollution filled the air.

“We are also mulling over implementing the odd-even scheme for the running of vehicles,” Arvind Kejriwal, the Chief Minister of Delhi, said. That would see about half of Delhi’s privately owned vehicles ordered off the roads, with odd and even-numbered license plates allowed to operate on alternating days.

Even the air quality monitors installed at the U.S. Embassy in Delhi, which sits in one of the cleanest and greenest patches in the city, registered an AQI over 360 on Friday, well into the most dire, “hazardous” level on the AQI chart displayed on the embassy’s website.

Residents of the Indian capital weren’t likely to see much improvement quickly, with weather conditions expected to remain calm and the seasonal crop stubble burning likely to continue.

India’s Environment Minister, Bhupender Yadav, on Wednesday blamed the opposition-run northern state of Punjab for failing to stop farmers burning off the remains of their harvested summer crops.
 
“There is no doubt over who has turned Delhi into a gas chamber,” Yadav said in a tweet. 

Punjab’s top politician, Bhagwant Mann, defended his administration, saying it only took office half a year ago and calling for a collaborative effort by state and federal authorities to address the problem.

The Delhi government is following a Graded Response Action Plan (GRAP) to combat air pollution in the city. The stricter measures were taken Friday as the average air quality worsened to “Severe Plus,” with the AQI over 450.

“It is the responsibility of all of us to take initiative at every level to stop pollution,” said Delhi’s state environment minister Gopal Rai earlier in the week.

The Indian capital is choked with toxic air most winters thanks to a confluence of factors, but a significant proportion of the smog does come from the huge farm fires in the neighboring states of Punjab, Haryana and Uttar Pradesh. 

Many farmers burn off the remains of their crops, the stubble left sticking out of the ground, to prepare their fields for winter crops. It’s a much cheaper option than transporting the stubble for proper disposal.

The practice has been formally banned by the country’s Supreme Court, and farmers were warned they would face fines for violating the decree, but it has served as a weak deterrent.

Between September 15 and October 31 this year, Punjab state alone recorded 16,004 farm fires — almost 3,700 more than during the same period last year. Haryana state has recorded 1,921 farm fires this year.

Satellite imagery from NASA’s Fire Information for Rescue Management System showed a dense patch of red dots on Tuesday, which indicate live fires, in Haryana over the past 24 hours.
