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.

Seventy-seven per cent children below five years of age in Jammu and Kashmir were not able to access basic healthcare services like immunisation during the lockdown imposed to curb the spread of COVID-19, CRY said on Monday citing a study.

The 'Rapid Online Perception Study about the Effects of COVID-19 on Children' was conducted during the first and second phases of the lockdown based on responses of parents and primary caregivers from all across the country, including Jammu and Kashmir, the NGO said in a statement.

It said a total of 387 respondents from Jammu and Kashmir participated in the study.

"Seventy-seven per cent children of age 0-5 years were not able to access basic healthcare services such as immunisation during lockdown - necessarily imposed to curb the spread of COVID-19 pandemic in Jammu and Kashmir," Child Rights and You (CRY) said.

It said as immunisation programmes witnessed a major setback during the lockdown across the country, the results of the survey across 23 states and Union Territories found nearly 50 per cent of parents with children below five years of age unable to access immunisation services.

"Worryingly, the figure was considerably high in Jammu and Kashmir with 77.14 per cent children below five years unable to get immunisation services," it added.

According to the study, in Jammu and Kashmir, nearly 35 per cent of the respondents said their children did not receive medical help during the lockdown, resulting in difficulties to cope with their children's illnesses and health hazards.

The study also talks about more systemic arrangements and logistical preparedness to ensure that children with no or compromised digital reach are not deprived from their Right to Education.

With online classes introduced as a substitute of schools during the lockdown, access to education for children remained a major issue of concern, as many of them, especially the ones from marginalised and financially poorer backgrounds found it difficult without smartphones and internet access.

The survey's findings revealed that nationally only 41 per cent households with children of school-going age could access online classes on a regular basis.

"Almost 90 per cent parents and primary caregivers reported that the lockdown has increased the screen time of their child to great or some extent. About half of the households recorded an increase of children's exposure to online activities during lockdown," it said.

The NGO said around 76 per cent parents agreed that they could keep a watch of their children's online activity to some extent.
