At poll rally, Yogi calls Indian Army 'Modi ji ki sena'

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.

United Nations, Jun 6: The COVID-19 pandemic, which has presented challenges for several nations, could be an “opportunity” for India to speed up the health insurance scheme Ayushman Bharat, especially with a focus on primary healthcare, WHO chief Tedros Adhanom Ghebreyesus has said.

WHO Director-General Ghebreyesus was responding to a question on the COVID-19 situation in India, where the number of coronavirus cases are increasing rapidly. India went past Italy on Friday to become the sixth worst-hit nation by the COVID-19 pandemic.

India saw a record single-day jump of 9,887 coronavirus cases and 294 deaths on Saturday, pushing the nationwide infection tally to 2,36,657 and the death toll to 6,642, according to the health ministry.

"Of course COVID is very unfortunate and it's challenging for many nations but we need to look for opportunities too. For instance for India, this could be an opportunity to speed up Ayushman Bharat, especially with a focus on primary health care. I know there is a very strong commitment from the government to speed up the implementation of Ayushman Bharat and with primary healthcare and community engagement, I think we can really turn the tide,” Ghebreyesus said during a press briefing in Geneva on Friday.

Ayushman Bharat is the world’s largest health insurance scheme and was launched by the Narendra Modi government in 2018. Last month, Modi had said that the number of people who have benefited from the scheme crossed the one crore-mark.

The scheme aims to cover more than 500 million beneficiaries and provide coverage of Rs 500,000 per family per year.

Referring to the Ayushman Bharat scheme, Ghebreyesus added that “using and speeding up what has started could actually help in India and that's what WHO was very appreciative by the way when Ayushman Bharat started. And this could be a very good opportunity actually to test that and speed up and use it to really fight this pandemic.”

New Delhi, May 8: India's count of COVID-19 cases on Friday rose to 56,342 including 1,886 deaths, according to the Ministry of Health and Family Welfare.

Currently, there are 37,916 active cases while 16,539 COVID-19 positive patients have been cured/discharged and one has migrated.

Maharashtra has the highest number of cases with 18,120 followed by Gujarat with 7,013 cases and Delhi with 5,980 cases.
