India breathes easy as Cities record minimal air pollution due to coronavirus lockdown

The world's largest coronavirus lockdown

The world’s largest lockdown means all factories, markets, shops, and places of worship are now closed, most public transport suspended and construction work halted, as India asks its citizens to stay home and practice social distancing. So far, India has more than 1,300 confirmed cases of Covid-19, including 35 deaths.

When India imposed a nationwide lockdown a week ago, it was designed to stop the imminent spread of the novel coronavirus.

But grinding this country of 1.3 billion people to a near halt has also provided a temporary remedy to another pressing health issue: suffocating pollution levels.

Though Covid-19 is proving to be deadly for us humans, it has an unintended beneficiary too — the earth. As cities see bluer skies and clearer water, most people are united in their belief that our planet is getting a much-deserved rest. Amidst all this gloom and doom, let’s look at the proverbial silver lining and see the positive consequences of the coronavirus pandemic.

Already, data shows that the main cities are recording much lower levels of harmful microscopic particulate matter known as PM 2.5, and of nitrogen dioxide, which is released by vehicles and power plants.

Pollution levels drop Satellite images released by NASA and the European Space Agency show a dramatic reduction in nitrogen dioxide emissions in major Chinese cities and northern Italy between January and February. As toxic gases released by vehicles, power plants and industrial facilities drop drastically, the air quality in cities has improved drastically. Similar patterns for carbon dioxide emissions were also observed.

The reductions in pollution also mean avoiding thousands of death due to air pollution as well as reducing the percentage of lung-related diseases.

While the effect of this in China is the most visible and sustained one till now, there is no doubt that all cities and countries in lock down will be following a similar route in the days to come.

Nowhere is this more visible than the renowned canals of Venice, where a tourist ban has caused motorised speedboats and Gondolas to stay off the water, leading to clear water for the first time since forever. Schools of fish are now clearly visible in the water.

Animals on the streets Netizens were overjoyed at seeing pictures of animals wandering into locked down cities, emboldened by the absence of humans. While some of the pictures turned out to be fake, such as the one showing drunken elephants taking a nap in China’s Yunnan province, it is true that creatures that live in the city’s shadows are venturing out on to the streets. For example, in Nara in Japan, Sika deer (the Bambi-lookalikes) have been spotted wandering through city streets and subway stations, chomping on potted plants. Raccoons were spotted on a beach in Panama. Wild turkeys and boars have made their presence felt in several areas. Monkeys were spotted fighting for food in Thailand.

There have also been reports of students in university campuses talking about how they are seeing more birds these days.  While most of them are foraging for food, the highlight is that they can do so without fear and danger. And while animals, especially wild ones, are resourceful and will quickly adapt to changes, it will be helpful if we can put out some water and food for the strays in our locality.

Humanity rises to the occasion It’s one of those rare occasions where the whole world is a family. Countries are sending masks, medical teams and experts to one another, working together to finding a possible cure or vaccine and sharing big data and information with each other without any hesitation. Within cities, youngsters are volunteering to run errands and do shopping for the sick and the elderly, the most vulnerable groups right now. Social media is filled with praise for doctors and medical staff at hospitals as well as positive messages about how to get through these difficult times.

Perhaps the biggest takeaway from the pandemic is the realisation that we need to make changes to our lifestyle and thought process. As some people rightly pointed out on social media, no matter how rich or powerful we are, all it takes is a micro–organism to remind us that we are all just humans.

From becoming fully aware of the impact of our actions on the planet to learning to live with limited resources – individual learnings are many. Industry leaders are grappling with supply chain disruptions (and reducing their dependency on one country or supplier) and technical changes (facilitating work from home and adopting technology in routine operations in a big way). Governments are realising the strengths and weaknesses of their medical infrastructure and social policies.

The world as such is learning to live with fear and uncertainty and still look for some bright spots of hope.

When India imposed a nationwide lockdown a week ago, it was designed to stop the imminent spread of the novel coronavirus.

But grinding this country of 1.3 billion people to a near halt has also provided a temporary remedy to another pressing health issue: suffocating pollution levels.

The world’s largest lockdown means all factories, markets, shops, and places of worship are now closed, most public transport suspended and construction work halted, as India asks its citizens to stay home and practice social distancing. So far, India has more than 1,300 confirmed cases of Covid-19, including 35 deaths.

Already, data shows that the main cities are recording much lower levels of harmful microscopic particulate matter known as PM 2.5, and of nitrogen dioxide, which is released by vehicles and power plants.

PM 2.5, which is smaller than 2.5 micrometers in diameter, is considered particularly dangerous as it can lodge deep into the lungs and pass into other organs and the bloodstream, causing serious health risks.

The sudden fall in pollutants and the subsequent blue skies signal a dramatic shift for India — which has 21 of the world’s 30 most polluted cities, according to the IQAir AirVisual’s 2019 World Air Quality Report.

In the capital, New Delhi, government data shows the average concentration of PM 2.5 plunged by 71% in the space of a week — falling from 91 microgram per cubic meter on March 20, to 26 on March 27, after the lockdown began. The World Health Organization considers anything above 25 to be unsafe.

The data from the Central Pollution Control Board (CPCB), part of India’s Environment Ministry, was collated by the Centre for Research on Clean Air and Energy (CREA).

Nitrogen dioxide went from 52 per cubic meter to 15 in the same period — also a 71% fall. Mumbai, Chennai, Kolkata and Bangalore have also recorded a fall in these air pollutants.

“I have not seen such blue skies in Delhi for the past 10 years,” said Jyoti Pande Lavakare, the co-founder of Indian environmental organization Care for Air, and author of upcoming book “Breathing Here is Injurious To Your Health.”

“It is a silver lining in terms of this awful crisis that we can step outside and breathe.”

Even before the national lockdown started on March 25, the phased shutdowns in India were having an impact.

During the first three weeks of March, the average nitrogen dioxide levels declined by 40-50% in the cities of Mumbai, Pune and Ahmedabad, compared with the same period in 2018 and 2019, said Gufran Beig, a scientist with the System of Air Quality and Weather Forecasting And Research (SAFAR) under India’s Ministry of Earth Sciences.

“The reduced fossil fuel emissions due to (the) transport sector and slowdown in other emissions-related activity is slowly reducing the air pollutants,” Beig said.

The nationwide curfew in India on March 22 also resulted in the lowest one-day traffic pollution levels on record, analysis from CREA said. Other dangerous pollutants, PM2.5 and the larger PM10, which are less than 10 micrometers in diameter, also dropped steeply, the report added.

“It is most likely that even the record of March 22 will be broken, and we are seeing more and more cleaner days as industries, transportation and energy generation and demand are reducing across the country,” said Sunil Dahia, an analyst based in New Delhi for CREA.

Similar patterns showing drastic falls in pollution levels were seen in parts of Europe and China since their lockdowns, as industry and transport networks grind to a virtual halt.

But this data is no reason to celebrate, Dahia said.

“This is a really grave situation which the entire world is grappling with,” Dahia said.

“Pollution is going down, but we cannot let the suffering of so many human beings be the way to clean the air,” Dahia said.”We can only use the outbreak of coronavirus as a learning lesson for us.”

It’s a lesson that is badly needed in India, activists say.

In November 2019, hundreds of Indians took to the streets in New Delhi to protest the levels of air pollution, after the city was blanketed in a dark yellow haze for several days.

Air pollution hit record high levels, forcing schools to close and flights to be diverted. Other cities in northern India also suffered.

Four months later, the skies are now clearing up. But the impact of living in such badly polluted conditions has left a hidden problem for residents: a potential vulnerability to the coronavirus pandemic — a severe respiratory disease.

India has one of the highest rates of respiratory disease in the world, and the world’s highest number of tuberculosis cases. Such widespread lung damage could potentially increase the risks associated with the coronavirus.

“(There are) very high levels of respiratory disease, even among young children, they have asthma, the nebulizer has become a normal thing to have in the house for families who can afford them,” said Lavakare from Care for Air.

According to the WHO, older people, and people with pre-existing medical conditions, including asthma, appear to be a higher risk of becoming severely ill with the virus.

Globally, deaths related to exposure to air pollution are of pandemic proportions, with 7 million deaths every year, the World Health Organization (WHO) said.

Care for Air said this should be a wake-up call for India to address the problem.

“Obviously, this is not the most ideal way to bring down air pollution, but it does prove that air pollution is manmade,” Lavakare said. “It gives a lot of encouragement and hope that we can bring pollution down.”

The coronavirus crisis also presents India with an opportunity to invest in a clean energy future, said Dahia from CREA.

“India (is) a highly fossil-fueled country,” said Dahia. “In order to tackle pollution, we need to tackle that.”

“When we come out of the outbreak, it will be interesting to see if we invest money in the cleaner future,” he added. “(Do) we ramp up the old fossil fuel based intensive industries, or we go towards more sustainable options.”

Lavakare said that at the minimum, the government should commit to keeping existing policy pledges.

“Governments cannot use this disruption as an excuse to go back against the gains that have been made,” she said. “Right now, we have a priority, we need to stop this big crisis.

“But when things are under better control … we need to move towards renewable energy faster. It would be really sad (if) we make the same mistake again, using coal and non-renewable energy.”
