Delhi Air Pollution: Delhi, the capital of India, is one of the most polluted cities in the world. But winter is especially cruel here. Each year, October, November, and December bring together an filthy environment, where over 18 million people are forced to live with a quilt of smog covering the capital and nearing cities.
2022 is nothing different. With the Air Pollution Index (API) at 337, the condition of Delhi’s environment is worsening.
The big question now is: what causes such disastrous air pollution in Delhi? What are the inferno reasons that pollute the air of entire northern India? And how are Delhites coping with the pollution?
An Overview of the Problem: Delhi Air Pollution
According to an India Today Web Desk article, Delhi has topped the list of the most polluted cities worldwide for the fourth consecutive year. The survey was initiated by SoGA, where the organization listed 20 polluted cities around the world in which Delhi ranked in the first position.
The air quality here in Delhi gets so bad in winter that the government needs to declare a public health emergency in response to exacerbating Delhi air pollution.
Like every year, the state government shut down schools, stalled all construction and industrial activities, and implemented an odd-even scheme traffic rotation to prevent air pollution.
“We can’t see the skyline. The air is unbreathable and traveling to work is extremely dangerous as you can see anything after 2 meters in the smog. This is not severe! This is an emergency—the next level of severity.”
ABHISHEK SINGH, A DELHI RESIDENT TOLD MZEMO
This condition happens every year when Delhi experiences a massive spike in air pollution—unfortunately, initiating the reason for two deaths in the country “EVERY MINUTE.”
What is Behind Delhi Air Pollution?
The unfortunate thing about the population of Delhi and the Delhi government is that they are not entirely responsible for the severe air pollution in their state.
According to SAFAR (System of Air Quality and Weather Forecasting and Research), 48% of Delhi’s air pollution is responsible for stubble burning in Punjab and Haryana.
Delhi’s AQI has been in the severe zone (401-500) for seven days between October 20 and November 14 this year. The percentage of farm fires that contributed to Delhi’s PM 2.5 on each of these days ranged from 26% to 48%.
The primary contributors to the dangerous situation in Delhi include
Stubble Burners – The Deed Owners
Though stubble burning has been an agricultural practice for centuries, the combined mechanical harvesters leave behind the stalk of the crop in the soil, which is around 2 feet high.
Therefore, to save money and time, farmers, instead of cutting the remaining stalk, set fire to the entire field so that a new batch of crops could be grown as soon as possible.
After the year 2009, stubble burning became even more popular when the governments of Haryana and Punjab passed a law in order to conserve water.
However, despite the concerning issue of air pollution in the past few years, the stubble-burning culture still continues.
The Himalayan Cool Winds Worsen the Delhi Air Pollution
The stubble burning in Punjab, Haryana, and Western UP creates fumes that blow away toward Delhi due to the strong winds during winter.
Combined with the cold winds coming from the Himalayas, this smoke gets trapped in Delhi’s air due to temperature inversion. The Himalayan mountain acts like a kind of barrier for Delhi, directing the smoke towards the capital.
Additionally, the weather also plays a significant role in worsening Delhi’s pollution. During the winters, cold mountain air rushes down from the Himalayas towards Delhi. Arriving cold air from the Himalayas beneath a layer of warm lowland air creates a dome over the state.
The warm air keeps pollution trapped on the ground with nowhere to go. So when stubble fire smoke reaches Delhi, it blends with urban pollution and forms toxic smog.
All these reasons combined, Delhi experiences dangerous air pollution that is so high that even air quality meters cannot accurately gauge its level.
The Co-Partners of Stubble Burners
During October-November, India celebrates their premier festival of Diwali, where lighting crackers worsen the situation in Delhi.
When the weather was considered, the survey discovered increases in PM2.5 concentrations, one of the most dangerous particles for human health, to approximately 40% high on the second day of the festival.
The Delhi government, however, made significant efforts to reduce the effects of burning crackers in Delhi pollution but failed to implement it thoroughly.
Stubble burning in Punjab and Haryana peaks in October end- and November. While the contribution of Diwali crackers significantly affects the air quality of Delhi.
Nevertheless, the contribution of stubble burning is Delhi’s primary cause of air pollution.
Delhi Air Pollution: The Solution
The unique geographical location of Delhi, coupled with its huge population, puts the state in a fragile position. In the interview with Mzemo, Abhishek said that the condition is getting worse every year.
However, there are a few solutions.
The controllable thing for Delhi is to use public transport, the Metro, or trains to travel. Secondly, reduce the waste or bifurcate the plastics and dry waste from wet. Third, implement strict rules and regulations against the Punjab and Haryana governments.
And most importantly, the government needs to come up with policies that to restore quality air in Delhi, especially when the life of 18 million people are at risk.
