Why Delhi has again become submerged by smog

Boys play soccer at a park enveloped by a blanket of smog, caused by a mixture of pollution and fog, in New Delhi, India, Tuesday, Nov. 6, 2012. Winter smogs are not uncommon in Delhi, but this year has been extreme

For the past week, I have been driving to work through a "pea-souper" - thick fog which has hung menacingly over Delhi and its neighbourhood.

The city has looked like a smoggy dystopia. Residents are mourning the death of the sun. Although the sun made a welcome appearance on Friday, some media reports say the smog is far from defeated and may return during the weekend.

My eyes hurt when I step out, and I spent days nursing a nagging headache. At work, many of my colleagues are wheezing, sniffing and coughing. The papers are full of stories of clinics overrun by patients suffering from respiratory ailments.

Winter smogs are not uncommon in Delhi, but this year has been rather extreme, sending air pollution levels way above permissible limits. The government has blamed farmers who burn straw in neighbouring states.

Independent environment groups insist that rising pollution is to blame.

Researchers belonging to the watchdog Centre for Science and Environment (CSE) say Delhi's air quality has deteriorated sharply - particulate matter in the air has risen by 47% between 2000 and 2011, while nitrogen dioxide levels has leapt by 57%.

Delhi, they say, is a gas chamber: its air contains a lethal cocktail of poisonous gases like nitrogen dioxide, carbon monoxide, ozone, and benzene. Farm fires have merely exacerbated what is an already bad situation.

The government appears to be rather blase about it all, blaming the weather (slow wind speeds, low temperatures and high humidity) and curiously, even hinting at conspiracy by neighbouring states ("It is as if it is deliberately being done to choke Delhi," Chief Minister Sheila Dikshit told a newspaper).

CSE Executive Director Anumita Roychowdhury, in charge of its air pollution and transportation programme, warns that government's response could have disastrous consequences. "Unfortunately, despite the scary hard facts about the elevated cocktail of pollution and health risks, the problem is being dismissed as a mere weather phenomenon," she said.

"In other parts of the world, governments issue warnings and take pollution emergency measures during such severe pollution episodes to protect public health. But we are doing nothing."

She is right. So what has gone so awfully wrong with Delhi's air, a decade after the city earned international plaudits for introducing green fuel and bringing down pollution levels?

Researchers believe that the unfettered growth in the number of vehicles, especially ones driven on diesel, is a key reason.

Delhi alone adds over 1,000 new vehicles every day, half of them diesel-fuelled. The capital has over 6.5 million vehicles, which is more than the total number of vehicles in the cities of Mumbai, Chennai (Madras) and Calcutta.

A thriving suburbia, including areas like Gurgaon, Noida and Faridabad, has meant that over a million vehicles - 70% of them cars - enter and exit Delhi every day. The new vehicles are better, the fuel is cleaner, but their sheer numbers do not do any good to the city's air.

It is not rocket science to conclude that Delhi needs to ramp up its public transport and cut down on private pollution-carrying vehicles.

To be fair, the city has come a long way in improving public transport: the quality of its passenger bus fleet is among the best in India, and an impressive metro railway now links most parts of the city.

But environmental groups like CSE say this is simply not enough.

"Delhi is taking too long to scale up its public transport," says Ms Roychowdhury.

Some 6,000 passenger buses run in the city - but the government itself admits it needs nearly three times that number to cater for peak passenger traffic. The city is bereft of pavements and footpaths, betraying a skewed planning ideology which favours cars over cycles and pedestrians.

Environmentalists also recommend higher parking charges for cars and a crackdown on unauthorised parking to force more car owners to use public transport - parking spaces, by one estimate, gobble up to 10% of Delhi's land, and daily additions of new cars creates demand for parking space that is bigger than 300 football fields every year.

Although cars are the mode of transport for only 14% of travel trips in the city, parking fills up disproportionately large spaces.

Environmentalists also suggest a hike in diesel prices, an upgrade emission standards, the introduction of buses for commuting to and from the suburbs and the imposition of congestion charges. But the authorities don't seem to be listening.

    Arun, #5, Well said!
    Correctly identifying the source of the problems is the first step towards the remedy. Smog is certainly not a new problem, and sensible solutions such as particulate reduction have been used in many cities across the world.

    This article is one of the better ones from the BBC on the subject: They haven't attempted to blame it on carbon dioxide.

    Much of the data and opinions of politicians and experts on the worsening air pollution of Delhi are old – being repeated for the past several years.

    Every winter City's “dreaded pollution problems” is back in the news with the CSE urging “urgent and tough measures” to clean up the City air and CM coming up with her blame game and vowing to do “something tough” to curb it.

    No concept of URBAN PLANNING in India due to:
    1)Politician Business man nexus in Land scams, Real Estate Scams, SEZ scams
    2)Black Money in these scams,

    Robert Vadra-DLF nexus expose by IAC/Kejriwal is a tip of this iceberg.

    Back in 1953 London was like that. Then a series of Clean Air acts included banning coal burning in the city. Gradually London air was cleaned up. Delhi is suffering not just from vehicles or just from straw burning but a whole mix of pollutants as accumulate in any large city. It is for populace to do something including pushing politicians to stop hot airing and sort the problem scientifically.

    I was in New Delhi a few years ago and it was sheer hell. My hotel room was high (I think 16th floor) and I was woken one morning by a dawn chorus of raucous crows. I looked out the window and saw a beautiful rising sun over the pall of smog below me. By the time I had finished breakfast, the smog had risen to higher than my room. Going out, my eyes had started streaming and I was coughing in 5 m.

    Ban burning of garbage,leaf litter,burning of coal and wood for cooking , this is what causes the wood smoke smell and adds particulate matter in the air. We seem to only blame vehicles for the pollution!l

    Much of Mr. Biswas' piece focuses on the need to limit automobile traffic and to improve mass transit, but the author later reveals that only 14% of journeys in Delhi are accomplished with private cars. Are cars truly the only major source of the problem, or is blaming commuters more politically convenient than industry? Benzene, for instance, cannot have been generated by vehicles.

    I flew into Delhi one Nov, two years ago. 20 mins before landing I smelled smoke, thought the plane was on fire for a second before realizing it was wood smoke. The entire city is thick with all forms of pollution and I felt sickly from landing to months after returning to the (relatively) clean air of Bangkok (!)
    Even now, writing this, I can taste the air of that awful place & will never return.

    Is it because Delhi is full of politicians? (hot air, windbag ...)
