ENVIRONMENT: UNABLE TO BREATHE
The past few weeks have passed by painfully for the residents of Lahore. In the crisp coolness of the year’s latter months, Lahoris normally enjoy sunny afternoons basking on their terraces or, venture out in the evenings for some hot soup or steaming coffee in celebration of winter. However, like the past two years, this year, too, a thick, stubborn blanket of grey smog settled around their heads, obstructing visibility, and causing health issues.
Smog is now being referred to as Lahore’s fifth season — and each year from autumn to winter this blanket descends upon the city, creating a dystopian scenario.
In Lahore, smog has been known to reduce visibility to up to 20 to 25 metres, often resulting in fatal accidents. The fact is that smog has indeed been claiming lives — some through traffic accidents, others through severe health problems.
Now referred to as Lahore’s fifth season, smog from autumn to winter has created a dystopia
In a 2014 study by the World Bank, the organisation claims that in Pakistan 22,000 people die every year on average because of air pollution-related issues. Globally speaking, the World Health Organisation (WHO) estimates that at least three million deaths a year are linked to exposure to what is known as outdoor air pollution. But indoor air pollution can be just as deadly. An estimated 6.5 million deaths (11.6 percent of all global deaths) across the world were associated with indoor and outdoor air pollution together (2012).
Meanwhile, the Health Effects Institute’s (HEI) chart showing the state of global air in 2018 showed that Pakistan saw 207 deaths in every 100,000 people. On a list of 12 countries, Pakistan was second, preceded only by Afghanistan and followed by India.
The HEI report shows that most of the world’s population lives in areas where air quality is unhealthy. An estimated 95 percent lives in areas where ambient (outdoor) fine particulate matter concentrations (small dust or soot particles in the air) exceed WHO’s Air Quality Guidelines. Almost 60 percent live in areas where fine particulate matter exceeds even the least stringent WHO interim air quality target of 35µg/m3 (micrograms per cubic metre).
The WWF’s Living Planet Report 2018 reveals that Lahore has now reached the top 10 list of the most polluted cities in the world. According to Air Visual, in the first week of December 2018, Lahore witnessed the worst air quality in the world, followed by New Delhi (India) and Pristina (Kosovo), with an air quality index (AQI) of 256, down from an AQI of 315 and a ranking of number two the week before.
With a yearly average of 68 µg/m3 of PM 2.5, which corresponds to an AQI of 155 — unhealthy — there are many reasons to be worried about the situation.
NOT FOG
Back in the Victorian era, thanks to coal fumes, London was hit by one of the deadliest and infamous smog in history, which continued each year until a Clean Air Act was introduced in 1956.
As in London, the smog in Lahore too was initially mistaken for a winter fog. But it didn’t take long for the facts to sink in as hundreds were affected with respiratory illnesses, and eye and skin allergies.
The toxic mixture of sulphur dioxide (SO2), ozone (O3), carbon monoxide (CO) — all highly noxious gases — airborne particulate matter such as soot, construction material, etc, and carcinogens, generally occurs in the lower part of the atmosphere, less than five kilometres above the ground.
In normal circumstances, hot air remains at ground level, with the air turning cooler and cooler as altitude increases. However, generally in winters, a situation can occur where temperature inversion takes place. Hot air is trapped underneath a cap of cold air, not allowing the smoke and dust to disperse. Instead, smoke and dust particles sink downwards and stay there.
BACKGROUND
In a 2009 report by the Pakistan Environment Protection Agency (EPA), it was found that there was a large presence of high suspended particulate matter in the air, especially in urban areas of the country. This very fine particulate matter (PM 2.5) of size 2.5 micron and below was found to be as high as three times the safe standards (35 micro gram/m3) in Lahore especially, out of three major cities being monitored.
Trans-boundary air pollution from neighbouring countries also added to poor air quality. The Pakistan Economic Survey states that dust and smoke particulates in the atmosphere of Lahore is “twice the world average” and “five times” higher than the developed world, while the WHO estimates that air pollution in both Karachi and Lahore is “20 times higher” than the global standards.
Environmental activists have been quick to raise their concerns.
When the first smog hit in 2016, it was pointed out that the construction of the Punjab government’s Orange Line Train had caused an increase in suspended dust particles including PM 10 and PM 2.5. There were also electricity problems, which ended up in factories burning bad fuel for power. Even rain was delayed due to climatic change. The Lahore High Court took notice of the issue.
But the situation ensued again next year.
Under Shahbaz Sharif, a smog commission was formed and a smog policy was adopted and submitted to the court, which approved it.
In September 2018, the Environmental Protection Department (EPD) announced that ‘Punjab would be closing down its 100,000 brick kilns for 70 days’. The initial date was October 20, but the hue and cry raised by kiln owners delayed closure to November 3.
“We want to convert all kilns to the new zigzag technology which ensures uniform distribution of heat, minimises the effect of burning coal on the environment and reduces fuel emissions,” says Naseemur Rehman, director of Environment Impact Assessment (EIA) section of the EPD. “We are giving them time to change, but the ones which will not, will be closed down.”
As stern as the EPD sounds, environmentalist Aleem Butt says that it hasn’t done much, as out of 11 proposed steps in the policy, only one has been fully completed — the agenda of planned urban and industrial development.
There has been absolutely no work done on introducing low sulphur fuels, installation of vehicular pollution control devices, better traffic management, building a forecast for air pollution, designing urban forests, or any regional environmental agreements made, especially with India.
Instead, the EPD has been mostly focusing on adopting Euro 2 standards for vehicles (European emission standards for road vehicles set in order to define acceptable levels of exhaust emissions), controlling road dust and the open burning of waste and crop residue, and the greening of industrial processes. Even these have only been partially undertaken.
