New Delhi, Apr 9: With an increase of 540 positive COVID-19 cases reported in the last 24 hours, India's tally of coronavirus cases has risen to 5,734, said the Ministry of Health and Family Welfare on Thursday.

Out of the 5,734 cases; 5,095 are active COVID-19 cases and 472 cases have been recovered/discharged and one case migrated.
The death toll has also risen to 166 after 17 new deaths were reported in the last 24 hours.

Maharashtra is the worst-hit state 1,135 positive cases so far and while Tamil Nadu is second with 738 positive cases. Delhi's tally has risen to 669 cases. 

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.

Expressing concern over the ban imposed on TikTok by the government of India, Facebook CEO Mark Zuckerberg has reportedly called the development in the south Asian country “worrisome”.

TikTok was amongst the 59 Chinese apps that were banned in India but why it hogs the maximum limelight because TikTok had the second-largest user base in India with over 200 million users.

As per The Verge writer Casey Newton, Zuckerberg was worried about TikTok’s India ban. Although it soon cashed into the opportunity and released a TikTok clone “Reels”, the government’s reason behind banning the app in India wasn’t received well by Mark Zuckerberg. 

He had said that if India can ban a platform with over 200 million users in India without citing concrete reasons, it can also ban Facebook if something goes amiss on the security and privacy front.

Why Mark finds it particularly worrisome because Facebook is already involved in a lot tussle with the governments across the world involving national security concerns. 

“Facebook already faces fights around the world from governments on both the left and the right related to issues that fit under the broad umbrella of national security: election interference, influence campaigns, hate speech, and even just plain-old democratic speech. Zuckerberg knows that the leap from banning TikTok on national security grounds to banning Facebook on national security grounds is more of a short hop,” the report by Casey read.

Facebook till now has not faced any kind of issue in India but considering the debacle with the other governments, it is not entirely wrong to worry about its future in India if any national security issue arises. Back in 2016, Facebook’s Free Basics service, which means a free but restricted internet service, was banned in India by the telecom regulators. 

The TRAI had said that the Free Basic services were banned in India because it violated the principles of net neutrality. With Free Basics services, Facebook had planned to bring more unconnected users online. But since 2016, there has been no major tussle between the Indian government and Zuckerberg due to national security issues.
