Mild tremors felt in Delhi, NCR, Chennai and eastern India

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.

May 7: Accusing the BJP government in Karnataka of "medieval barbarism" and treating migrants as worse than "bonded labourers", CPI(M) general secretary Sitaram Yechury on Wednesday hit out at the state's decision to stop workers from returning to their homes in different parts of the country citing requirements of the construction sector.

The Karnataka government has withdrawn its request to the railways to run special trains to ferry migrant labourers to their home states, hours after builders met Chief Minister B S Yediyurappa to apprise him of the problems the construction sector will face in case they left.

"This is worse than treating them as bonded labour. Does the Indian constitution exist? Are there any laws in the country? This BJP state government is throwing us back to medieval barbarism. This will be stoutly resisted,” Yechury said in a tweet.

The railways is running Shramik Special trains to ferry to their home towns migrants who were stranded at their places of work during the lockdown.

So far, it has run more than 115 such trains.

The Principal Secretary in the Revenue Department N Manjunatha Prasad, who is the nodal officer for migrants, had requested the South Western Railways on Tuesday to run two train services a day for five days except Wednesday, while the state government wanted services thrice a day to Danapur in Bihar. However, later, Prasad wrote another letter within a few hours that the special trains were not required. Several migrants in the city were desperate to return home as they were out of jobs and money.

Yechury also lashed out at the central government over reports that it owed states and industry Rs 3 trillion and accused the centre of shifting the burden of fighting the pandemic to the state governments.

“While shifting the entire burden of fighting the pandemic on to the State governments, Modi government is not even paying their legitimate dues. After November 2019, Centre has not paid the GST compensation dues for the rest of the financial year, i.e., March 2020.

“Modi government has the right to loot while crores of people & States are left with nothing but the right to starve?,” he tweeted.

New Delhi, Apr 22: Prime Minister Narendra Modi on Wednesday said that The Epidemic Diseases (Amendment) Ordinance, 2020, manifests his government's commitment to protecting healthcare workers braving COVID-19 on the frontline.
"The Epidemic Diseases (Amendment) Ordinance, 2020, manifests our commitment to protect each and every healthcare worker, who is bravely battling COVID-19 on the frontline. It will ensure the safety of our professionals. There can be no compromise on their safety!," Prime Minister Modi tweeted.
The Central government on Wednesday brought an ordinance to end the violence against health workers, making it a cognizable, non-bailable offence with the imprisonment of up to seven years for those found guilty.

"We have brought an ordinance under which any attack on health workers will be a cognizable, non-bailable offence. In the case of grievous injuries, the accused can be sentenced from 6 months to 7 years. They can be penalised from Rs 1 lakh to Rs 5 lakh," Union Minister Prakash Javadekar briefed media after the meeting of the Cabinet.

"Such crime will now be cognisable and non-bailable. An investigation will be done within 30 days. Accused can be sentenced from three months to five years, and penalised from Rs 50,000 up to Rs 2 lakh," said Javadekar.

Moreover, if the damage is done to vehicles or clinics of healthcare workers, then a compensation amounting to twice the market value of the damaged property will be taken from the accused, said Javadekar.
