Indian Army supports US-Taliban negotiated peace deal: CDS

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 20: The government-imposed upper and lower limits on airfares may be extended beyond August 24 depending upon how the situation turns out, Aviation Secretary P S Kharola said on Saturday.

The government resumed domestic passenger flights from May 25 after nearly two months of suspension to combat the coronavirus outbreak, but placed lower and upper limits on airfares depending upon the flight duration.

It had said on May 21 that these limits would be in place for a period of three months.

"Depending on how the situation turns out, the fare band may have to adjusted beyond that (August 24) also. But right now, it is only for three months," Kharola said at a press conference here.

International passenger flights continue to remain suspended in the country.

However, the government started Vande Bharat Mission on May 6 to help stranded people reach their destinations through special flights.

Aviation Minister Hardeep Singh Puri said at the conference that during phase 3 and phase 4 of the mission, private domestic airlines have been approved to operate 750 international flights to repatriate people stranded amid the coronavirus pandemic.

New Delhi, Apr 23: Congress president Sonia Gandhi on Thursday accused the BJP of spreading the virus of communal prejudice and hatred in the country, asserting that "grave damage" is being done to social harmony

Addressing a meeting of the Congress Working Committee, Gandhi said it should worry every Indian and her party will have to work hard to repair this damage.

"Let me also share with you something that should worry each and every one of us as Indians. When we should be tackling the coronavirus unitedly, the BJP continues to spread the virus of communal prejudice and hatred," she said.

"Grave damage is being done to our social harmony. Our party, we will have to work hard to repair that damage," the Congress president added

Former prime minister Manmohan Singh, former Congress president Rahul Gandhi and top Congress leaders attended the meeting through video conference

This is the second time the CWC, the Congress' top decision-making body, is meeting through video-conferencing in the past three weeks ever since the lockdown was enforced to contain the coronavirus threat.

The Congress president said the coronavirus pandemic has increased disturbingly in the past three weeks and called upon the government to increase testing for it

Gandhi said she has written several times to the prime minister since the lockdown was enforced and suggested several measures and constructive cooperation

"Unfortunately, they have been acted upon only partially and in a miserly way. The compassion, large-heartedness and alacrity that should be forthcoming from the central government is conspicuous by its absence," she said

The Congress chief said the focus of the party must continue to be on successfully engaging with health, food security and livelihood issues.

She claimed that around 12 crore people have lost jobs in the first phase of the lockdown and urged the government to provide a relief package for the MSME sector, which accounts for one-third of the GDP

Gandhi called upon the government to provide food and financial security to migrants and jobless stranded at various places and were desperate to reach back home

"We have repeatedly urged PM there is no alternative to testing, tracing and quarantine. Unfortunately, testing still remains low, testing kits still in short supply," she noted

Gandhi said trade, commerce and industry have come to a virtual halt and crores of livelihoods have been destroyed.

"The central government does not appear to have a clear idea on how the situation will be managed after May 3rd. A lockdown of the present nature after that date would be even more devastating," she said

Former prime minister Manmohan said the success of the lockdown will be judged finally on India's ability to tackle COVID-19

He also said the cooperation between the Centre and states was key to success of the country's fight against coronavirus

Singh said it is necessary to focus on a number of issues in the fight against coronavirus

The fight against COVID-19 would very much depend upon the availability of resources, he noted

Rajasthan chief minister Ashok Gehlot said unless the central government comes forward to financially help states, the fight against COVID-19 will get weakened

"Unless there is a big financial package for states, how will normalcy return to states post lockdown," he asked

Chhattisgarh chief minister Bhupesh Baghel said unless the Centre rises to the occasion and provides financial assistance to states, how will the fight against COVID-19 be won

Puducherry chief minister V Narayanasamy said the Union government has not given any assistance to the states

"How will states survive in times of crisis. We are not enemies but have to act and work together," Narayanasamy said at the CWC meet.
