Reduction in air pollution during lockdown in India may have prevented 630 premature deaths: Study

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Jun 19: Billionaire Mukesh Ambani on Friday announced that his oil-to-telecom conglomerate Reliance Industries is now net debt-free after raising a record Rs 1.69 lakh crore from global investors and a rights issue in under two months.

Reliance raised Rs 1.15 lakh crore from global tech investors by selling a little less than a quarter of the firm's digital arm, Jio Platforms Ltd, and another Rs 53,124.20 crore through a rights issue in the past 58 days.

Taken together with last year's sale of 49 per cent stake in fuel retailing venture to BP Plc of UK for Rs 7,000 crore, the total fund raised is in excess of Rs 1.75 lakh crore, the company said in a statement.

Reliance had a net debt of Rs 1,61,035 crore as on March 31, 2020. "With these investments, RIL has become net debt-free," it said.

"I have fulfilled my promise to the shareholders by making Reliance net debt-free much before our original schedule of March 31, 2021," Ambani said.

Jio Platforms - which houses the country's youngest but largest telecom firm Reliance Jio, raised Rs 1,15,693.95 crore from leading global investors including Facebook, Silver Lake, Vista Equity Partners, General Atlantic, KKR, Mubadala, ADIA, TPG, L Catterton and PIF since April 22, 2020.

Saudi Arabian sovereign wealth fund PIF buying 2.32 per cent stake in the unit for Rs 11,367 crore on June 18 "marks the end of Jio Platforms' current phase of induction of financial partners," the statement said.

Alongside, Reliance launched India's biggest right issue, which was subscribed to 1.59 times.

Though the rights issue size was Rs 53,124 crore, the company has got only 25 per cent of the money as the remaining is to be paid only next fiscal.

Ambani had at the company's annual general meeting on August 12, 2019, announced a roadmap for Reliance to become a net debt-free company before March 31, 2021.

"We have a very clear roadmap to becoming a zero net-debt company within the next 18 months that is by March 31, 202," he had said last year highlighting strong interest from strategic and financial investors in consumer businesses, Jio and Reliance Retail.

In the statement on Friday, he said he was both delighted and humbled to announce the fulfillment of the promise.

"Exceeding the expectations of our shareholders and all other stakeholders, again and yet again, is in the very DNA of Reliance," he said.

"Therefore, on the proud occasion of becoming a net debt-free company, I wish to assure them that Reliance in its Golden Decade will set even more ambitious growth goals, and achieve them," he added.

He said over the past few weeks, phenomenal interest was received from the global financial investor community in partnering with Jio.

"As our fundraising milestone from financial investors is achieved, we sincerely thank the marquee group of financial partners and warmly welcome them into Jio Platforms," he said.

"I also express my heartfelt gratitude to all the retail and institutional investors, both domestic and foreign, for their overwhelming participation in our record-setting Rights Issue," he added.

New Delhi, May 4: Rebutting the Congress' criticism, the BJP said on Monday that the railways has subsidised 85 per cent of ticket fare for special trains being run for migrant workers and the state governments have to pay the remaining 15 per cent.

The ruling party also accused the Congress of promoting indiscriminate movement of people which, it said, would lead to "faster spread" of coronavirus infection "just like we saw in Italy", and asked if this is what Sonia Gandhi wants.

The counter-charge from BJP leaders, including its spokesperson Sambit Patra and information technology department in-charge Amit Malviya, came after Congress president Sonia Gandhi hit out at the central government for making migrants pay for their train fare and asked her party's state units to pick the tab.

Congress leader Rahul Gandhi also took a swipe at the railways, saying, on one hand, it is seeking ticket fare from people stranded in various states while on the other it is donating Rs 151 crore to the PM-CARES Fund.

Responding to him, Patra said, "Rahul Gandhi ji, I have attached guidelines of MHA which clearly state that 'No tickets to be sold at any station'. Railways has subsidised 85% & state govt to pay 15%. The state govt can pay for the tickets (Madhya Pradesh's BJP govt is paying). Ask Cong state govts to follow suit," Patra tweeted.

The BJP leader further clarified that for each 'Shramik Express', special trains being run for migrants to take them back to their native places during the lockdown, about 1,200 tickets to the destination are handed by the railways to the state government concerned.

State governments are supposed to clear the ticket price and hand over the tickets to workers, he said.

He said the BJP government in Madhya Pradesh is doing so and asked Rahul Gandhi to tell the Congress-ruled states to follow suit.

Hitting out at Sonia Gandhi, Malviya tweeted, "Congress is obviously upset at how well India has handled Covid. They would have ideally wanted a lot more people to suffer and die. Promoting indiscriminate movement of people would lead to faster spread of infection, just like we saw in Italy. Is this what Sonia Gandhi wants?"

BJP MP Subramanian Swamy claimed that migrant workers returning home will not have to pay money as the rail travel will be free from now onwards.

"Talked to Piyush Goyal office. Govt will pay 85% and State Govt 15%. Migrant labour will go free. Ministry will clarify with an official statement," he tweeted.
