India may have just gotten the wake up call it needed to start getting serious about its growing pollution problem. A study put out this week by Tel Aviv University reports that that Indian megacities are seeing a faster increase in pollution than the cities in the classic environmental villain to the east, China. According to the paper, between 2002 and 2010, Bangalore saw the second-highest increase in air pollution levels in the world at 34%, and Indian cities including Pune, Mumbai, Nagpur, and Ahmedabad, among others, also saw double-digit increases. Because the pollution measured reflects a combination of industrial and weather-related particles like dust, its not possible to say that this is entirely a man-made problem. But the fact that Indias population grew faster than Chinas in the last decade means that the air in Indias cities is doomed to get worse before it gets better.
It doesnt seem fair that China gets both the job-supplying manufacturing sector and the relatively better pollution news. (Its increasing in Chinese cities, too just not as fast). But no one here could claim the information to be much of a shock. Though this is my first winter in Delhi, everyone keeps telling me that its normal this time of year for the Indian capital to get smoggy. But how smoggy is normal? So smoggy that companies spam my phone with texts for Aryuvedic asthma cures? Apparently so, because Ive got them. When winter kicks in, the cooler temperatures and still air always bring an annual period of haze to the city, but the pervasive murk that enshrouded the city for the first few weeks of November raised more concerns than usual, and not just mine. According to researchers at Indias Center for Science and Environment, levels of respirable particulate matter (PM10) in mid November were up 47% over what they were that time last year, and nitrogen dioxide levels were up 57%.
Officials have been on the defense, and they should be. New Delhi Chief Minister Sheila Dikshit announced the state had commissioned one of Indias best universities to study the causes of this years bad smog, in addition to proposing a series of quick fixes to help clear the air like restricting diesel generator use and banning trucks not bound for Delhi from entering the city. She also has blamed the burning of straw in neighboring states of Haryana and Punjab, a claim that officials there dismissed, correctly pointing out that if that were the problem, theyd be covered in smog, too.
The gray cocoon that enshrouded the city earlier this month is at bay for now, which means we can see the sky. Thats a nice change. But itll be back. In a study released earlier this year, India ranked last out of 132 countries surveyed by Yale and Columbia in terms of its air quality and it effects on human health. Due to its high-emissions vehicles and heavy reliance on coal, the country has particularly serious levels of high particulate matter, which lead to respiratory infections, and the problem is seen both in cities like Delhi and smaller cities around the nation.
You always have an increase in respiratory cases this time of the year, partly because of the worsening air quality and partly because of the seasonal changes, says Dr. S K Chhabra, head of the Department of Cardiorespiratory Physiology at the Vallabhbhai Patel Chest Institute in Delhi. He says hes seeing more asthma and bronchitis patients in the past few weeks, as well more cardiac patients with angina, which is aggravated by the lowered oxygen levels during heavy pollution. People with preexisting lung or heart disease, smokers, young children and the elderly are particularly susceptible. When the wind starts again, there will be less cases.
That doesnt make it okay. The Delhi government has taken steps in the past that have helped control the citys pollution levels, like rolling out vehicles that run on natural gas to reduce emissions, building a metro system to encourage public transportation, and limiting the amount of commercial traffic coming through town. Last week, the Center for Science and Environment called on officials to do much more, including enforcing emissions checks on private and commercial vehicles, banning open fires in the city, and using a smog alert system to let citizens know when the pollution is particularly risky. Earlier this month, the city announced it would expand monitoring, install electronic displays charting air quality around the city, and issue smog alerts and health advisories, according to the Hindustan Times.
Those are steps that have a proven track record in other cities. Growing up in the 1980s in Los Angeles, we used to have regular smog days, when public schools would cancel our phys ed classes because the city advised it was unhealthy for kids to be outside. (Some amazing pictures of the bad old days in LA here.) L.A. has mostly cleaned up its act through a combination of citizen activism, better technology and better regulation. The alerts were good public health practice, sure, but they did more than that. They were a reminder that heavy air pollution, even if it was the norm, was not normal. They are also a reminder to citizens that if officials arent doing all they can to get things back to normal, theyre not doing their job. If Indias private sector can send me regular text messages about Aryuvedic cures for asthma, surely I could get a courtesy note from the government I pay taxes to when air pollution levels might give me an asthma attack.
