Bengaluru, Apr 8: The University Grants Commission (UGC) has asked all universities and higher education institutions across the nation to set up helpline to combat mental health issues among students during the Covid-19 crisis and nation-wide lockdown period.

In an official circular, the UGC stated that, "It is important to address psychological concerns of students and to address mental health and for the well-being of students, universities/colleges and higher education institutions should setup mental health helplines."

These helplines need to be monitored by counselors and other identified faculty members. "It is important for students to stay calm and stress-free. This can be achieved through telephones, e-mails, digital and social media platforms," says UGC.

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.

India is among 58 nations, including 27 European Union members, who have moved a draft resolution demanding evaluation of the World Health Organisation (WHO)'s response towards the novel coronavirus pandemic.

The European Union-led draft resolution on global COVID-19 response is set to be tabled at the upcoming World Health Assembly on Monday.

The draft resolution demands initiation "at the earliest appropriate moment to review experience gained and lessons learned from the WHO-coordinated international health response to COVID-19".

"We are deeply concerned by the morbidity and mortality caused by COVID-19 pandemic, the negative impacts on physical and mental health and social well-being, the negative impacts on economy and society and the consequent exacerbation of inequalities within and between countries," read the draft.

"We express solidarity to all countries affected by the pandemic, as well as condolences and sympathy to all the families of the victims of COVID-19," it added.

The resolution says timelines are to be evaluated regarding "recommendations the WHO made to improve global pandemic prevention, preparedness, and response capacity".

The WHO on January 23 declare a global health emergency, but did not declare it and waited for a week for its director-general Tedros Adhanom Ghebreyesus to return from China.

By that time, COVID-19 cases increased 10 times and the virus entered 18 countries.

According to Health Policy Watch, till as late as February, the WHO did not support countries for imposing travel restrictions to China.

"When countries began evacuating their citizens from Wuhan, the COVID-19 epicentre, the WHO said it did not favour this step".

The WHO finally declared it a pandemic on March 11.

The global health body has come under criticism not just from the US for its response being "China-centric".
