Delhi air pollution: 29 red alert days in November

New Delhi: Delhi’s air quality was so poor in the month of November this year that according to China’s pollution warning system, 29 days of the 30 would have been termed as ‘red alert’ days.

A red alert is issued in China if there are more than 350 micrograms of coarse particulate matter (PM10) in one cubic metre.

According to Greenpeace India’s analysis of the National Air Quality Index, the period of September to November in Delhi had 33 such days, 29 of which were in November.

While the standard level of PM10 per cubic meter is 100 micrograms, the monitoring station at Anand Vihar recorded the level at 1,433 micrograms earlier in the week. That is a staggering 14 times more than the average level of particulates.

A red alert in China shuts down polluting industries and schools, while vehicular pollution is strictly checked and directives issued. A similar system in India is being called forth by activists.

Greenpeace India campaigner, Sunil Dahiya said, “We have monitoring stations and the data is available on the government’s sites. But, the average citizens are not aware of the data. There is a need for an alarm system.”

India’s own governmental data showed that several cities in North India were in worse shape than Beijing, added Dahiya.

“We can no longer deny that we are in a state of crisis, and equally, that this crisis creates the imperative to come up with policies to put an end to India’s air pollution crisis,” said Dahiya.

Both national and regional plans are required on a long-term basis to truly affect the growing pollution crisis, according to environmentalists. The general population needs to be made aware of the crisis so that a collective effort can come into place.

“The Delhi Government’s car rationing policy and move to shut down power plants will reduce pollution, but we need to move to renewable energy,” added Dahiya.

‘Humans Have Caused Pollution and Humans Can Fix It too’, Says UN Environment Head; Asserts Asia Must Lead Efforts for a Pollution-Free Earth

World Health Organization figures show Asia has 25 of the world's 30 most-polluted cities in terms of fine particles in the air that pose the greatest risks to human health

Bangkok, September 9, 2017 : Asia-Pacific — home to more than half the world’s population and some of its fastest-growing economies — is a key battleground in the fight against pollution, one of the biggest threats to the planet and its people, the U.N. environment chief said.

An estimated 12 million people die prematurely each year because of unhealthy environments, 7 million of them due to air pollution alone, making pollution “the biggest killer of humanity,” Erik Solheim told the first Asia-Pacific Ministerial Summit on the Environment in Bangkok this week.

Humans have caused pollution and humans can fix it, said Solheim, executive director of UN Environment, in an interview with Reuters at the four-day summit.

“The struggle for a pollution-free planet will be won or lost in Asia — nowhere else,” said the former Norwegian minister for environment and international development.

The sheer size of Asia-Pacific, as well as its continued economic growth, put it at the heart of the challenge, he added.

The region’s development has been accompanied by worsening pollution of its air, water and soil. Its emissions of planet-warming carbon dioxide doubled between 1990 and 2012, and the use of resources such as minerals, metals and biomass has tripled, according to the United Nations.

World Health Organization figures also show Asia has 25 of the world’s 30 most-polluted cities in terms of fine particles in the air that pose the greatest risks to human health. The pollution comes largely from the combustion of fossil fuels, mostly for transport and electricity generation.

Solheim said Asia is also a major contributor of plastic polluting the world’s oceans — and solutions can be found in the region. He pointed to a huge beach cleanup campaign in Mumbai that inspired Indian Prime Minister Narendra Modi to overhaul the country’s waste management system.

“There’s enormous environmental opportunity,” Solheim said. “Asia has by and large strong governments, and they have the ability to fix problems.”

Coal no longer king?

Solheim said fighting pollution by moving toward renewable energy sources such as wind and solar would also benefit efforts to curb climate change, which scientists say is stoking more deadly heatwaves, floods and sea-level rise around the world.

But environmentalists worry that Asia’s demand for coal, the most polluting of the major fossil fuels, is likely to grow for years to come.

Figures from a forum organized by the King Abdullah Petroleum Studies and Research Center in Singapore earlier this year show that some 273 gigawatts of coal power are still being built, although much more has been put on hold.

In July, analysts told Reuters that Japan, China and South Korea are bank-rolling coal-fired power plants in Indonesia despite their pledges to reduce planet-warming emissions under the Paris climate deal.

The landmark 2015 Paris Agreement seeks to limit the rise in average world temperatures to well below 2 degrees Celsius above pre-industrial times. Experts say curbing or ending the use of coal is required if this goal is to be reached.

Globally, many countries — including China — are shutting down or suspending plans for coal-fired power plants as costs for wind and solar power plummet.

Solheim is optimistic, noting that the International Energy Agency significantly raised its five-year growth forecast for renewables led by China, India, the United States and Mexico.

“There are very, very few people in the world who believe that the future is coal,” he said. “I think we will see the shift [to renewables] happening much faster than people tend to believe.”

On U.S. President Donald Trump’s decision to pull his nation out of the Paris Agreement, Solheim sees a silver lining.

“The surprising judgment of history may be that Donald Trump did a lot of service to this fight against climate change by withdrawing, because he galvanized the reaction of everyone else,” said Solheim.

“All the big, iconic companies of modern capitalism — Apple, Google, Microsoft, Amazon — they immediately said, ‘We will move into the green economy.'” (VOA)

  • This new technique maps urban air pollution at 100,000 times greater spatial resolution than is possible with traditional government air quality monitors
  • The new technique could address major air quality monitoring gaps worldwide
  • The research was conducted in partnership with the US-based non-profit Environmental Defense Fund (EDF), Google and Aclima

New York, June 9, 2017: Using specially equipped Google Street View cars to measure air quality on a block-by-block basis, researchers, including one of Indian-origin, have developed a detailed and extensive local map of air pollution for an urban area.

Most large urban areas tend to have only one air quality monitor for every 100 to 200 square miles. In comparison, the new mobile approach maps air pollution every 100 feet, or at about four to five locations along a single city block.

“Using our approach and analysis techniques, we can now visualise air pollution with incredible detail. This kind of information could transform our understanding of the sources and impacts of air pollution,” Apte added.

The research was conducted in partnership with the US-based non-profit Environmental Defense Fund (EDF), Google and Aclima, a California-based provider of environmental sensors.

By integrating Aclima’s sensor system into Google Street View cars, the team mapped air pollution in 78 square miles of Oakland, California, over an entire year, collecting one of the largest data sets of air pollution ever measured of single city streets.

This new technique maps urban air pollution at 100,000 times greater spatial resolution than is possible with traditional government air quality monitors, according to a study published in the journal Environmental Science & Technology.

The team believes that their hyper-local mobile measurement system could be implemented in many cities throughout the world, providing detailed air quality information for citizens, families, local governments and scientists.

The new technique could address major air quality monitoring gaps worldwide and has the potential to transform the way air pollution is monitored in urban areas as well as shed light on the health effects on city dwellers.

“You could use this information when you’re picking a school for your kids. Is there a school with a playground that might have better air quality because your kid has asthma,” Apte said.

“This hyper-local information about consistent air quality can be really useful for people, especially those who are vulnerable because of age or health condition,” Apte noted.(IANS)
