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.

New Delhi, Jun 29: The Supreme Court on Monday asked the Central government to find out the facts related to blacklisting and canceling of visas of foreign nationals who attended the congregation of Tablighi Jamaat in Nizamuddin area here.

A three-judge bench headed by Justice AM Khanwilkar and also comprising Justices Dinesh Maheshwari and Sanjiv Khanna asked the Centre to find out the facts related to the matter and fixed it for further hearing on July 2.

The apex court asked Solicitor General Tushar Mehta "if visas of these foreigners are canceled, then why are they still in India?"

"You (Centre) can deport them. If visas are not canceled, then, it is a different situation," the court said. The top court was hearing a number of petitions challenging blacklisting and cancellation of visas filed by few foreigners.

Mehta sought more time to file a reply on the matter, after which the court posted the matter for further hearing on July 2.

The petitions, filed by the foreign nationals from 35 countries, have sought directions to the Ministry of Home Affairs (MHA) to remove their names from the blacklist, reinstate their visas and facilitate their return to their respective countries.

The petitions sought to declare the decision of the MHA of blacklisting the foreign nationals who attended the Tablighi Jamaat congregation as "arbitrary".

"Unilateral blacklisting of 960 foreigners by the Home Ministry vide press release dated April 2, 2020, and the subsequent blacklisting of around 2500 foreigners as reported on June 4, 2020, is in violation of Article 21. Therefore, it is void and unconstitutional as the petitioners have neither been provided any hearing nor notice or intimation in this regard," the plea said.

One of the petitioners named Fareedah Cheema, a Thai national in the seventh month of her pregnancy, said she was quarantined in March, like other foreign nationals but was released from quarantine only in late May and is still at a facility under restricted movements, without the avenue to go back to her home nation and experience the birth of her child with security and dignity, with her loved ones.

These foreign nationals presently in India were blacklisted for a period of 10 years from traveling to India for their alleged involvement in Tablighi Jamaat activities.

The Home Ministry had said that foreign Tablighi Jamaat members, who were staying in India in violation of visa rules during the nationwide lockdown implemented to combat the COVID-19 spread, have been blacklisted.
A large congregation organised by Tablighi Jamaat in the national capital in March had emerged as a major COVID-19 hotspot in the country.

The government had said the decision of banning the foreign Tablighi Jamaat members was taken after details of foreigners found illegally living in mosques and religious places emerged from various states across the country.

New Delhi, June 8: Only 20.26 lakh migrant workers of the targeted 8 crore such labourers have received free food grains in May and June (2020), according to data released by the Ministry of Consumer Affairs, Food and Public Distribution.

In the middle of May, as part of the Rs 20 lakh crore Atma Nirbhar Bharat package, the Modi government had announced that migrant labourers who are not covered under the National Food Security Act (NFSA) or any state-run PDS scheme, will receive free food grains for two months.

"Non-card holders shall be given 5 kg wheat or rice per person and 1 kg chana per family per month for the next 2 months. About 8 crore migrants will benefit from this scheme that will cost the government Rs 3500 crore,” Finance Minister Nirmala Sitharaman had said at a press conference following PM Modi’s announcement.

But the Ministry of Consumer Affairs, Food and Public Distribution said on Sunday, "The states and UTs have lifted 4.42 LMT (lakh metric tonne) of food grains and distributed 10,131 MT of it to 20.26 lakh beneficiaries."

It added, "The Government of India also approved 39,000 MT pulses for 1.96 crore migrant families. Around 28,306 MT gram/dal have been dispatched to the states and UTs. A total 15,413 MT gram have been lifted by various states and UTs". The state governments, the ministry added, had distributed only 631MT (metric tonnes) of gram so far.

Because of the constant movement of migrant workers, the Centre had said that the states will be responsible for identifying the migrants and subsequent food distribution.

The Centre claims it is spending approximately Rs 3,109 crore for food grains and Rs 280 crores for grams/chana under this package.
