Chindia Alert: You’ll be Living in their World Very Soon
aims to alert you to the threats and opportunities that China and India present. China and India require serious attention; case of ‘hidden dragon and crouching tiger’.
Without this attention, governments, businesses and, indeed, individuals may find themselves at a great disadvantage sooner rather than later.

Between January 20 and April 4, PM2.5 levels across the country fell by more than 18 per cent, according to the environment ministry
But observers say that as soon as the nation’s factories and roads get back to normal, so too will the air pollution levels

China’s air quality has improved dramatically in recent weeks as a result of the widespread city lockdowns and strict travel restrictions introduced to contain the
. But experts say the blue skies could rapidly disappear as factories and roads reopen under a government stimulus plan to breathe new life into a stalled economy.
According to the Ministry of Ecology and Environment, between January 20 and April 4 the average concentration of PM2.5 – the tiny particles that pose the biggest risk to health – fell by 18.4 per cent from the same period of last year.
Meanwhile, the average number of days with good air quality – determined as when the air pollution index falls below 100 – rose by 7.5 per cent, it said.
Satellite images released by Nasa and the European Space Agency showed a dramatic drop in nitrogen dioxide emissions in major Chinese cities in the first two months of 2020, compared with a year earlier.
According to Nasa, the changes in Wuhan – the central China city at the epicentre of the initial coronavirus outbreak – were particularly striking, while nitrogen dioxide levels across the whole of eastern and central China were 10 to 30 per cent lower than normal.
The region is home to hundreds of factories, supplying everything from steel and car parts to microchips. Wuhan, which has a population of 11 million, was placed under lockdown on January 23, but those restrictions were lifted on Wednesday

Nitrogen dioxide is produced by cars, power plants and other industrial facilities and is thought to exacerbate respiratory illnesses such as asthma.
The space agency said the decline in air pollution levels coincided with the restrictions imposed on transport and business activities.
That was consistent with official data from China’s National Development and Reform Commission, which recorded a 25 per cent fall in road freight volume and a 14 per cent decline in the consumption of oil products between January and February.

Liu Qian, a senior climate campaigner for Greenpeace based in Beijing, said the restrictions on industry and travel were the primary reasons for the improvement in air quality.
According to official data, in February, the concentrations of PM2.5, nitrogen dioxide and sulphur dioxide – a toxic gas that comes mostly from industrial burning of coal and other fossil fuels – all fell, by 27 per cent, 28 per cent and 23 per cent, respectively.
“The causes of air pollution are complicated, but the suspension of industrial activity and a drop in public transport use will have helped to reduce levels,” Liu said.
As the epicentre of the Covid-19 pandemic has shifted to the United States and
, human and industrial activity in China is gradually picking back up, and so is air pollution.
Lauri Myllyvirta, lead analyst with the Centre for Research on Energy and Clean Air in Helsinki, said that levels of nitrogen dioxide pollution, measured both by Nasa satellites and official stations in China, started inching back up in the middle of March and had returned to normal levels by the end of the month.
That coincided with the centre’s findings – published on Carbon Brief, a British website on climate change – that coal consumption at power plants and oil refineries across China returned to their normal levels in the fourth week of March.
How the Wuhan experience could help coronavirus battle in US and Europe

Ma Jun, director of the Institute of Public & Environmental Affairs, a Beijing-based charity, said a stimulus plan to kick-start the economy would have a significant impact on air pollution.
“Once industrial production is fully resumed, so are the emission levels,” he said. “Unless another outbreak happens and triggers another lockdown, which would be terrible, the improvement achieved under the pandemic is unstable and won’t last long.”
After the 2008 financial crisis, Beijing launched a 4 trillion yuan (US$567.6 billion) stimulus package that included massive infrastructure investment, but also did huge damage to the environment. In the years that followed, air pollution rose to record highs and sparked a public backlash.
Even before the Covid-19 outbreak, China’s economy was slowing – it grew by 6.1 per cent in 2019, its slowest for 29 years – and concerns are now growing that policymakers will go all out to revive it.
“Local governments have been under huge pressure since last year, and there are fears that environmental regulations will be sidelined [in the push to boost economic output],” Ma said.
But Beijing had the opportunity to get it right this time by investing more in green infrastructure projects rather than high-carbon projects, he said.
“A balance between economic development and environmental protection is key to achieving a green recovery, and that is what China needs.”

Five million masks are being distributed at schools in India’s capital, Delhi, after pollution made the air so toxic officials were forced to declare a public health emergency.
A Supreme Court mandated panel imposed several restrictions in the city and two neighbouring states, as air quality deteriorated to “severe” levels.
All construction has been halted for a week and fireworks have been banned.
The city’s schools have also been closed until at least next Tuesday.
Delhi’s Chief Minister Arvind Kejriwal said Delhi had been turned into a “gas chamber”.
The masks are being handed out to students and their parents, and Mr Kejriwal has asked people to use them as much as possible.
The levels of tiny particulate matter (known as PM2.5) that enter deep into the lungs are 533 micrograms per cubic metre in the city. The WHO recommends that the PM2.5 levels should not be more than 25 micrograms per cubic metre on average in 24 hours.
As thick white smog blanketed the city, residents started tweeting pictures of their surroundings. Many are furious that the situation remains the same year after year.
The hashtags #DelhiAirQuality and #FightAgainstDelhiPollition are trending on Twitter.
One of the main reasons for air quality in the city worsening every year in November and December is that farmers in the neighbouring states of Punjab and Haryana burn crop stubble to clear their fields. It’s made worse by the fireworks during the Hindu festival of Diwali.
There are other reasons too, including construction dust, factory and vehicular emissions, but farm fires remain the biggest culprit.

More than two million farmers burn 23 million tonnes of crop residue on some 80,000 sq km of farmland in northern India every winter.
The stubble smoke is a lethal cocktail of particulate matter, carbon dioxide, nitrogen dioxide and sulphur dioxide.
Using satellite data, Harvard University researchers estimated that nearly half of Delhi’s air pollution between 2012 and 2016 was due to stubble burning.
The burning is so widespread that it even shows up in satellite photos from Nasa.
What are PM 2.5 particles?
Particulate matter, or PM, 2.5 is a type of pollution involving fine particles less than 2.5 microns (0.0025mm) in diameter
A second type, PM 10, is of coarser particles with a diameter of up to 10 microns
Some occur naturally – e.g. from dust storms and forest fires, others from human industrial processes
They often consist of fragments that are small enough to reach the lungs or, in the smallest cases, to cross into the bloodstream as well
