India coronavirus: Can the Covid-19 lockdown spark a clean air movement?

When India shut down last month and suspended all transport to contain the spread of coronavirus, the skies over its polluted cities quickly turned an azure blue, and the air, unusually fresh.

As air pollution plummeted to levels unseen in living memory, people shared pictures of spotless skies and even Himalayan peaks from cities where the view had been obscured by fog for decades.

On one social messaging group, a resident of the capital, Delhi, which regularly records some of the foulest air in the world, celebrated the city’s “alpine weather“. Politician and author Shashi Tharoor wrote that the “blissful sight of blue skies and the joy of breathing clean air provides just the contrast to illustrate what we are doing to ourselves the rest of the time”.

Less than six months ago, Delhi was gasping for breath. Authorities said air quality had reached “unbearable levels”. Schools were shut, flights were diverted, and people were asked to wear masks, avoid polluted areas and keep doors and windows closed.

Delhi and 13 other Indian cities feature on a list of the world’s 20 most polluted. It is estimated that more than a million Indians die every year because of air pollution-related diseases. Industrial smoke, vehicular emissions, burning of trash and crop residue, and construction and road dust are the major contributors.

As urban Indians gazed at the skies and breathed clean air inside their homes, researchers hunkered down to track data on how the grinding lockdown – now extended to 3 May – was impacting air pollution across the country.

“This was an unprecedented opportunity for us to take a close look at how air pollution levels have responded to an extraordinary development,” Sarath Guttikunda, who heads Urban Emissions, an independent research group that provides air quality forecasts, told me.

Federal pollution control authorities quickly reported a marked improvement in air quality levels in 85 cities.

Dr Guttikunda and his team of researchers looked at the data spewed out by the 100-odd air quality monitoring stations all over India. They decided to concentrate on the capital Delhi and its suburbs – a massive sprawl called the National Capital region, where more than 20 million people live. Last winter, air pollution here had reached more than 20 times the World Health Organization’s safe limit.

The deadliest particle in Delhi’s foul air is the tiny but deadly PM 2.5, which increases the likelihood of respiratory and cardiovascular diseases. They primarily come from combustion – fires, automobiles and power plants.

Urban Emissions found the levels of PM 2.5 in Delhi during the lockdown plummeted to 20 micrograms per cubic metre with a 20-day average of 35.

To put this into context, between 2017 and 2019, the monthly average of PM 2.5 in the capital was up to four times higher. (The national standard is set at 40, and the WHO has an annual average guideline of just 10 micrograms per cubic metre.)

“If 35 is the average lowest available PM2.5 with limited local emissions, it means that at least 70% of the pollution is locally generated,” Mr Guttikunda told me.

His study also found a marked dip in PM 10, caused mainly by road and construction dust, and nitrogen dioxide, which comes mainly from vehicular emissions, and nearly 90% of vehicles are off the road.

“The current crisis has shown us that clear skies and breathable air can be achieved very fast if concrete action is taken to reduce burning of fossil fuels,” says Sunil Dahiya, of the Centre for Research on Energy and Clean Air, which has also been tracking air pollution levels during the lockdown.

But will this prompt change? After all, urban Indians’ and the media’s panic and outrage during the deadly winter pollution every year soon gets lost in the fog of summer heat and concerns over monsoon rains and droughts.

“We don’t yet have a democratic demand for clean air,” Arunabha Ghosh, Chief Executive Officer of the Council on Energy, Environment and Water, a leading climate think tank, told me. Orders to clean up the air have almost always come from the courts, responding to pleas by NGOs.

However, Dr Ghosh still hopes that “the experience of blue skies and fresh air could be a trigger to create a democratic demand for clean air in India”.

Crises often trigger life changing reforms. A fatal four-day “pea-souper” that engulfed London in 1952 and killed thousands provoked the passing of the Clean Air Act to reduce the use of smoky fuels.

China tried to clean up its air several times before hosting marquee international events – like the Beijing Olympics in 2008, the World Expo in Shanghai and the Guangzhou Asian Games in 2010 – before sliding back to grey, smoky skies.

But many believe the 2014 Apec meeting in Beijing, when China hosted 21 heads of Asia-Pacific economies, was a turning point. The rare blue skies over Beijing spawned the phrase ‘Apec blue‘. In a rush to clean its air, China introduced a set of far-reaching measures. Over the next four years, this resulted in a 32% drop in average pollution across major Chinese cities.

So could a lockdown to prevent the spread of a pandemic, which has imperilled the health and livelihoods of millions, trigger similar policy changes to clean up India’s air?

Could it move to a shift in reducing traffic on the road by asking people to work from home in shifts now that millions have experienced clean air for the first time in years? (Facing energy shortages after the loss of the Fukushima nuclear power plant, Japan unleashed a Cool Biz campaign to cut down air conditioning in workplaces and reduce carbon emissions by asking office workers to shed their suits.)

Or can India use some of the money from an inevitable stimulus to help kick-start the economy go towards helping green industries? Renewables, experts say, creates more jobs than coal: India has already created nearly 100,000 jobs in solar and wind energy firms.

Can the country use the windfall revenues accruing from the steep decline in oil prices – most of India’s oil is imported – to provide rebates to polluting factories to set up much-needed emission control equipment?

“We have to learn lessons to deploy the economic recovery from the pandemic. We need growth, jobs and sustainable development,” says Dr Ghosh. Cleaning up the air could be the key. For too long, India – and Indians – have ignored their right to breathe easy.

What’s more, if China can reduce air pollution by 32% in four-and-a-half years, why can’t India pledge to reduce pollution by 80% in 80 cities by 2027, which is our 80th anniversary of Independence? asks Dr Ghosh.

It’s a good question.

Russian border becomes China’s frontline in fight against second virus wave

SUIFENHE, China (Reuters) – China’s northeastern border with Russia has become a frontline in the fight against a resurgence of the coronavirus epidemic as new daily cases rose to the highest in nearly six weeks – with more than 90% involving people coming from abroad.

Having largely stamped out domestic transmission of the disease, China has been slowly easing curbs on movement as it tries to get its economy back on track, but there are fears that a rise in imported cases could spark a second wave of COVID-19.

A total of 108 new coronavirus cases were reported in mainland China on Sunday, up from 99 a day earlier, marking the highest daily tally since March 5.

Imported cases accounted for a record 98. Half involved Chinese nationals returning from Russia’s Far Eastern Federal District, home to the city of Vladivostok, who re-entered China through border crossings in Heilongjiang province.

“Our little town here, we thought it was the safest place,” said a resident of the border city of Suifenhe, who only gave his surname as Zhu.

“Some Chinese citizens – they want to come back, but it’s not very sensible, what are you doing coming here for?”

The border is closed, except to Chinese nationals, and the land route through the city had become one of few options available for people trying to return home after Russia stopped flights to China except for those evacuating people.

Streets in Suifenhe were virtually empty on Sunday evening due to restrictions of movement and gatherings announced last week, when authorities took preventative measures similar to those imposed in Wuhan, the central Chinese city where the pandemic ripping round the world first emerged late last year.

The total number of confirmed cases in mainland China now stands at 82,160 as of Sunday, and at the peak of the first wave of the epidemic on Feb 12 there were over 15,000 new cases.

Though the number of daily infections across China has dropped sharply from that peak, China has seen the daily toll creep higher after hitting a trough on March 12 because of the rise in imported cases.

Chinese cities near the Russian frontier are tightening border controls and imposing stricter quarantines in response.

Suifenhe and Harbin, the capital of Heilongjiang, are now mandating 28 days of quarantine as well as nucleic acid and antibody tests for all arrivals from abroad.

In Shanghai, authorities found that 60 people who arrived on Aeroflot flight SU208 from Moscow on April 10 have the coronavirus, Zheng Jin, a spokeswoman for the Shanghai Municipal Health Commission, told a press conference on Monday.

Residents in Suifenhe said a lot of people had left the city fearing contagion, but others put their trust in authorities’ containment measures.

“I don’t need to worry,” Zhao Wei, another Suifenhe resident, told Reuters. “If there’s a local transmission, I would, but there’s not a single one. They’re all from the border, but they’ve all been sent to quarantine.”

US-China tech war’s new battleground: undersea internet cables

  • A push to connect Pacific nations highlights a submarine struggle for dominance over the world’s technology infrastructure
  • The ambitions of Chinese tech giants like Huawei, which have laid thousands of kilometres of cable, are of increasing concern to Washington

In the contest between the US and China for dominance over the world’s technology
infrastructure, the latest battle is taking place under the Pacific Ocean.
While the US has been upping the pressure on its allies not to include equipment made by Chinese telecom giants like Huawei and ZTE in their 5G systems, Chinese companies have gained a foothold in some of the world’s most essential communications infrastructure – undersea internet cables.
Smart telecom cables: climate change hope or submarine spying tech?
14 Dec 2019
Almost all global data communications flow through cables under the ocean – just one per cent travels by satellite – and Chinese companies have quietly been eroding US, European and Japanese dominance over the backbone of the internet, the undersea cable market. Now, they have trained their sights on connecting one of the most virtually remote parts of the globe, the Pacific Island countries.
Of the 378 cables currently operating worldwide, 23 are under the Pacific. But many of these cables run right by Pacific Island nations on their paths between hubs in Los Angeles, Tokyo and Singapore.

Despite the volume of data flowing under the Pacific Ocean, just half a million of the 11 million people living in Pacific Island countries and Papua New Guinea – less than five per cent – have access to a wired internet connection and only 1.5 million to a mobile connection, according to the United Nations Economic and Social Commission for the Asia Pacific (UNESCAP), compared with 53 per cent of people in Thailand and 60 per cent in the Philippines.

More than US$4 billion worth of cables are to come into service by 2021, continuing a trend in which US$2 billion worth of cables have come online every year since 2016, and six of these cables will connect Pacific Island countries.

The push to connect Pacific Island nations to the latest generation of internet infrastructure has received extra scrutiny from the US and its allies like Australia
over the involvement of Chinese tech companies.

SECURITY CONCERNS

While the US has moved to block Huawei from supplying equipment to its allies’ 5G networks, experts say Chinese tech companies could contest the US, EU and

Japan’s

long-standing dominance over global data traffic through investments in subsea cables.

Chinese tech giants like Huawei have entire divisions devoted to undersea connectivity that have laid thousands of kilometres of cable, and Chinese state telecommunication companies such as China Unicom have access to many of the existing trans-Pacific cables.

But a panel led by the US Department of Justice has held up a nearly complete trans-Pacific cable project over concerns about its Chinese investor, Beijing-based Dr Peng Telecom & Media Group.

The project, the Pacific Light Cable Network, could be the first cable rejected by the panel on the grounds of national security – despite being backed by American tech giants Google and Facebook – setting a precedent for a tougher US stance on Chinese involvement in subsea cables.

Craige Sloots, director of sales at Southern Cross Cable Network, which operates the largest existing sets of trans-Pacific cables, said for any new cable, regulators were likely to scrutinise the ownership of the companies involved and the maker of the project’s equipment.
These two factors, said Sloots, “pragmatically limit some of the providers you can use if you want to connect through the US”.
Experts say that Hong Kong, where the stalled Pacific Light Cable would land, was previously considered a more secure shore landing point than mainland China. But people close to the project say the recent unrest in the city has made this distinction less relevant, according to The Wall Street Journal.

Similar concerns caused a proposed Huawei-backed cable linking Vanuatu with Papua New Guinea to be called off last year after Australia stepped in to fund its own cable instead.
Just months after the government-owned Solomon Islands Submarine Cable Company agreed to the project with Huawei in mid-2017, Canberra put up US$67 million to connect Sydney with the Solomon Islands and Papua New Guinea with cables laid under the Coral Sea by Nokia’s Alcatel Submarine Networks.
Simon Fletcher, CEO of Vanuatu company Interchange, which had been planning another cable in the neighbourhood connecting Vanuatu with the Solomon Islands, said the Coral Sea project undercut the viability for small private businesses to operate in the fledgling market, where services had historically been provided by international organisations like development banks. His company’s cable has been on pause since the announcement of the Coral Sea project, though Fletcher said it would go forward next year.

VIRTUALLY REMOTE

For years, as Japan, Hong Kong and Singapore became global hubs of high-speed internet data traffic, the cables criss-crossing the ocean floor passed by just off the shores of Pacific Island countries en route between hubs on either side of the ocean.

Tiziana Bonapace, director of UNESCAP’s information technology and disaster risk-reduction division, said the Pacific Islands remain one of the most disconnected areas in the world, where “a vast proportion of the population has no access to the internet”.

Over the past five years, international organisations like UNESCAP, the Asia Development Bank and the World Bank have been pushing for better connectivity in the region. The World Bank’s Pacific Regional Connectivity Programme has invested more than US$90 million into broadband infrastructure for Fiji, the Federated States of Micronesia, Kiribati, the Marshall Islands, Palau, Samoa and Tuvalu.

But the business case had never been good, said Bonapace.
“A cable has to travel thousands of kilometres just to connect a population smaller than one of Asia’s megacities,” she said. “As everything we do is somehow connected to the internet, the prospects for the Pacific to become virtually more remote are even higher.”
Even nations which are connected have tenuous infrastructure. In January, Tonga experienced a total internet blackout for two weeks after damage to its single cable. Most parts of the world were linked by multiple cables to prevent this type of outage, said Bruce Howe, professor of ocean and resources engineering at University of Hawaii.
“If these nations want to be part of the international economy, they need reliable communications,” Howe said.

DRAWING NEW LINES

In Papua New Guinea, where mobile internet currently reaches less than a third of the population, a partnership between local telecoms company GoPNG and the Export-Import Bank of China funded the new Huawei-built Kumul Domestic cable system, which came online this year.

The Southern Cross Next system, owned by Spark, Verizon, Singtel Optus and Telstra – the same group of shareholders which operates the massive 30,500km (19,000 mile) set of twin cables connecting the US with Australia and New Zealand known as Southern Cross – is planned to come online in 2022, and will connect directly to Fiji, Samoa, Kiribati and Tokelau.

Chinese telecoms company China Unicom counts the existing Southern Cross cables among its network capabilities – meaning it is likely to have access to the cable through a leasing agreement with one of the other companies that uses the cable, according to Canberra think tank the Australian Strategic Policy Institute (ASPI).

China Unicom and China Telecom also list the Asia America Gateway Cable System as one of their network capabilities, according to ASPI. The 20,000km (12,400-mile) cable came online in 2009 and connects the US, Guam, Hong Kong, Brunei, the Philippines, Singapore, Malaysia, Vietnam and Thailand.
It is owned by a consortium of carriers including AT&T, Telekom Malaysia, Telstra and Spark.
A cable backed by Google and the Australian Academic and Research Network connecting Japan and Australia through Guam is to come online early next year.

WHAT’S NEXT

Natasha Beschorner, senior digital development specialist at the World Bank, said that while there were challenges ahead in terms of broadband access and affordability, increased connectivity was starting to bring new opportunities to the Pacific.

“Digital technologies can contribute to economic diversification, income generation and service delivery in the Pacific,” Beschorner said. “E-commerce and financial technologies are emerging and governments are considering how to roll out selected services online.”

Experts say the industry has recently seen a switch from cables being mostly funded by telecommunication carriers to being funded by content providers, like Google and Facebook. Members of the private cable industry say content companies can afford to invest in cable infrastructure to ensure the supply chain for their customers, but that the competition puts the squeeze on the research-and-development budgets of other types of companies.

Sloots at Southern Cross predicted that the nations which connected directly to the massive next-generation cable – Samoa, Kiribati and Tokelau – would be able to function as connecting points for intra-Pacific cables.

“There’s a blossoming effect in capability once certain islands are connected,” Sloots said.

There is also the push to locate an exchange point within the Pacific so that internet data no longer has to travel to a hub in Tokyo or Los Angeles and back to Pacific nations when processing – a move that could ultimately lower the cost of broadband internet service for consumers in the Pacific.

Perhaps the most effective outcome could be for Pacific nations to cut the cord and receive their internet by satellite.

The Asian Development Bank has agreed to give a US$50 million loan to Singapore’s Kacific Broadband Satellites International to provide up to two billion people across the Asia-Pacific region with affordable satellite-based internet.

The project is to be launched into orbit by SpaceX next week and aims to begin providing service by early next year.
