Lahore’s Poor Air Quality Points to Pakistan’s Bigger Pollution Problem

Growing up in Lahore — Pakistan’s cultural capital — fall used to be the perfect time for Mariam to enjoy outdoor activities after months of scorching summer heat. Now, she cannot imagine the same for her young daughters as Lahore’s air, ranked the most polluted globally, becomes unusually toxic in cooler months.

“You can just smell, sometimes you can taste it, and feel it as well,” said the mother of two describing what it is like to breathe the polluted air.

With an AQI reading of 345 early in the day, Lahore ranked second worst city in the world for air pollution on Tuesday, according to the Air Quality Index or AQI run by IQAir, a Swiss air purifier manufacturer.

An AQI above 151 is unhealthy, while above 301 the air is hazardous for breathing.

IQAir’s index ranked Lahore the most polluted city of 2022.

Smog emergency

The city, along with several other in Pakistan’s biggest province Punjab,is under a month-long smog emergency since early November.

Smog – a combination of smoke and fog – is a specific phenomenon that occurs when certain pollution particles mix with cold, moist air and hang close to the ground, reducing visibility.

In a bid to reduce traffic congestion and exposure to toxic air, the top court in Punjab on Monday ordered the closure of government-run educational institutions on Saturdays until the end of January 2024. The court also asked the provincial government to come up with a work-from-home plan for the private sector.

A year-long emergency

For a few weeks in fall, smoke in Punjab’s air increases as Pakistani and Indian farmers on both sides of the divided state burn agricultural residue to prepare fields for planting the next crop. Environmentalists, however, say the government is in denial about the extent of Pakistan’s pollution problem, which is primarily driven by low quality, high-Sulphur fuel.

“Air pollution has always been an issue in Pakistani cities, going back the better part of 15 odd years,” Ahmad Rafay Alam, a Lahore-based environmental lawyer told VOA. “We have a year-long regional air pollution emergency and we tend to think of it as a Lahore smog issue.”

According to the Air Quality Life Index developed by the Energy Policy Institute at the University of Chicago, 98.3 of Pakistanis breathe air that is below the country’s own national air quality standard.

In 2017 the provincial Environmental Protection Department came up with an 11-point policy, on court orders, focusing on controlling emissions from vehicles and factories.

The court was, however, dissatisfied and constituted a smog commission for detailed analysis and recommendations on improving air quality.

Speaking to VOA, Naseem-ur-Rehman Shah, secretary of the provincial Environment Commission claimed that 80% of factories were now monitoring their emissions while 70-percent of brick kilns had moved to an environmentally friendly design

Still, data paints a terrifying picture.

“Every figure is telling you that the air pollution in Lahore is about, on the lower end, like 30, 40 times higher than the WHO safe limits,” said Abid Omar, founder of Air Quality Pakistan Initiative, a network of volunteers who monitor air quality using IQAir monitors.

Omar is based in Karachi which routinely competes with Lahore and Delhi for the worst air quality in the world.

Monitoring

For the city of nearly 15 million people, Punjab’s environmental agency gathers data from only five air quality monitors in Lahore.

Omar’s Pakistan Air Quality Initiative has 50 monitors feeding into IQAir’s Air Quality Index.

Shah’s department does not use PAQI’s data over standardization concerns but it is planning to add several monitors of its own.

In 2019, the provincial environmental regulator was forced to revise its air quality standards after it emerged officials were underreporting pollution by using low standards.

Alam represented the complainants in taking the regulator to court.

Knee jerk reaction

With air quality declining dramatically this month, the provincial and city administration have ramped up crackdown on smoke-emitting factories, brick kilns, and vehicles.

Citing city administration, local media reported that more than 16,000 vehicles were ticketed and over $100,000 dollars in fines imposed since the beginning of the emergency.

Omar calls such administrative measures a knee jerk reaction lacking long-term impact.

“Because it’s very random and ad hoc implementation, it’s not going to be an effective policy,” Omar said.

Shah called such criticism unfair. “We are working to eliminate sources of pollution,” he said.

Policy shift

“What we need to do is improve the quality of our refineries, which don’t produce high quality fuels … you have to transition to renewable energies, which is expensive and time consuming,” said Alam, pointing to studies that show fuel and energy sector are among the primary polluters in the country.

In May this year, Pakistan’s Ministry of Climate Change introduced the National Clean Air Policy. It aims to reduce harmful emissions in the next 10 years by introducing interventions in transport, industry, agriculture, waste and household sectors.

Such an overhaul will take time, money, and political will.

For Mariam, who runs three air purifiers in her home, the only option at the moment is to keep her daughters indoors as much as possible.

“It actually feels like … you’re being deprived of something very basic … not being able to breathe in fresh air.”

According to the Air Quality Life Index at the University of Chicago, Pakistanis are losing 3.9 years of life expectancy because of breathing toxic air. In Lahore and the rest of Punjab, residents are on track to lose between 3.7 to 4.6 years of life expectancy.

Solar Panels Over Canals in Gila River Indian Community Will Help Save Water

In a move that may soon be replicated elsewhere, the Gila River Indian Community recently signed an agreement with the U.S. Army Corps of Engineers to put solar panels over a stretch of irrigation canal on its land south of Phoenix.

It will be the first project of its kind in the United States to break ground, according to the tribe’s press release.

“This was a historic moment here for the community but also for the region and across Indian Country,” said Gila River Indian Community Governor Stephen Roe Lewis in a video published on X, formerly known as Twitter.

The first phase, set to be completed in 2025, will cover 1,000 feet of canal and generate one megawatt of electricity that the tribe will use to irrigate crops, including feed for livestock, cotton and grains.

The idea is simple: install solar panels over canals in sunny, water-scarce regions where they reduce evaporation and make renewable electricity.

“We’re proud to be leaders in water conservation, and this project is going to do just that,” Lewis said, noting the significance of a Native, sovereign, tribal nation leading on the technology.

A study by the University of California, Merced estimated that 63 billion gallons of water could be saved annually by covering California’s 4,000 miles of canals. More than 100 climate advocacy groups are advocating for just that.

Researchers believe that much of the installed solar canopies would additionally generate a significant amount of electricity.

UC Merced wants to hone its initial estimate and should soon have the chance. Not far away in California’s Central Valley, the Turlock Irrigation District and partner Solar AquaGrid plan to construct 1.6 miles (2.6 kilometers) of solar canopies over its canals beginning this spring and researchers will study the benefits.

Neither the Gila River Indian Community nor the Turlock Irrigation District are the first to implement this technology globally. Indian engineering firm Sun Edison inaugurated the first solar-covered canal in 2012 on one of the largest irrigation projects in the world in Gujarat state. Despite ambitious plans to cover 11,800 miles (19,000 kilometers) of canals, only a handful of small projects ever went up, and the engineering firm filed for bankruptcy.

High capital costs, clunky design and maintenance challenges were obstacles for widespread adoption, experts say.

But severe, prolonged drought in the western U.S. has centered water as a key political issue, heightening interest in technologies like cloud seeding and solar-covered canals as water managers grasp at any solution that might buoy reserves, even ones that haven’t been widely tested, or tested at all.

Still, the project is an important indicator of the tribe’s commitment to water conservation, said Heather Tanana, a visiting law professor at the University of California, Irvine and citizen of the Navajo Nation. Tribes hold the most senior water rights on the Colorado River, though many are still settling those rights in court.

“There’s so much fear about the tribes asserting their rights and if they do so, it’ll pull from someone else’s rights,” she said. The tribe leaving water in Lake Mead and putting federal dollars toward projects like solar canopies is “a great example to show that fear is unwarranted.”

The federal government has made record funding available for water-saving projects, including a $233 million pact with the Gila River Indian Community to conserve about two feet of water in Lake Mead, the massive and severely depleted reservoir on the Colorado River. Phase one of the solar canal project will cost $6.7 million and the Bureau of Reclamation provided $517,000 for the design.
