Over 250 terrorists killed in IAF air strikes, claims BJP chief Amit Shah

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, May 14: India may witness the death of additional 1.2-6 lakh children over the next one year from preventable causes as a consequence to the disruption in regular health services due to the COVID-19 pandemic, UNICEF has warned.

The warning comes from a new study that brackets India with nine other nations from Asia and Africa that could potentially have the largest number of additional child deaths as a consequence to the pandemic.

These potential child deaths will be in addition to the 2.5 million children who already die before their fifth birthday every six months in the 118 countries included in the study.

The estimate is based on an analysis by researchers from the Johns Hopkins Bloomberg School of Public Health published in the Lancet.  

This means the global mortality rate of children dying before their fifth birthday, one of the key progress indicators in all of the global development, could potentially increase for the first time since 1960 when the data was first collected.

There were 1.04 million under-5 deaths in India in 2017, of which nearly 50% (0.57 million) were neonatal deaths. The highest number of under-5 deaths was in Uttar Pradesh (312,800 which included 165,800 neonatal deaths) and Bihar (141,500 which included 75,300 neonatal deaths).

The researchers looked at three scenarios, factoring in parameters like reduction in workforce, supplies and access to healthcare for services like family planning, antenatal care, childbirth care, postnatal care, vaccination and preventive care for early childhood. The effects are modelled for a period of three months, six months and 12 months.  

In scenario-1 marked by 10-18% reduction of coverage of all the services, the number of additional children deaths could be in the range of 30,000 plus over three months, more than 60,000 over six months and above 120,000 over the next 12 months.

The numbers sharply rose to nearly 55,000; 109,000 and 219,000 respectively for scenario-2, which was associated with an 18-28% drop in all the regular services.

But in the worst-case scenario in which 40-50% of the services are not available, the number of additional deaths ballooned to 1.5 lakhs in the three months in the short-range to nearly six lakhs over a year.

The ten countries that could potentially have the largest number of additional child deaths are Bangladesh, Brazil, Congo, Ethiopia, India, Indonesia, Nigeria, Pakistan, Uganda and Tanzania.

In countries with already weak health systems, COVID-19 is causing disruptions in medical supply chains and straining financial and human resources.

Visits to health care centres are declining due to lockdowns, curfews and transport disruptions, and due to the fear of infection among the communities. Such disruptions could result in potentially devastating increases in maternal and child deaths, the UN agency warned.

Mumbai, Jan 12: Thousands of citizens on Sunday congregated in Mumbai's suburban Jogeshwari to oppose the new citizenship law, the proposed NRC and NPR.

They also condemned last Sunday's violence on the JNU campus in Delhi, where masked men ran riot and attacked students. Leftist organisations had claimed RSS-affiliated ABVP's role in the attack, a charge denied by the students' body.

Former Tata Institute of Social Science (TISS) general secretary Fahad Ahmed told PTI that they assembled under the aegis of 'Hum Bharat Ke Log' in Millat Nagar area.

"Prime minister Narendra Modi should call 56 students from across the country to debate on the CAA, NRC and NPR," Ahmed said in an apparent jibe at Modi's "56 inch chest" remark, which the latter had made ahead of the 2014 Lok Sabha polls.

"Why the PM is not talking to us? Why is he not communicating? Even the Britishers used to talk to Indians whom they ruled, but our PM is not talking to poor people," he alleged.

Bollywood actor Sushasht Singh also spoke on the occasion.

"We are people of this country and such acts (CAA) are tarnishing the image of our country," he said.

At the gathering, people waved banners with slogans like "I Am From Gujarat, My Documents Burned in 2002", "No CAA, Boycott NRC, Stop Dividing India, Don't Divide us", "Save Constitution", written on them.

A large number of police personnel were present at the venue.

The Citizenship Amendment Act (CAA), which was notified on January 10, grants Indian citizenship to non-Muslim minorities migrated to India from Afghanistan, Pakistan and Bangladesh till December 31, 2014, following persecution over their faith.

Massive protests were witnessed against the CAA, mainly by the student community, since its passage by Parliament in December last year.

Opposition parties have been dubbing the CAA an "anti-Muslim" legislation, a charge being debunked by the government.

The Congress and other parties like the TMC have also opposed the proposed National Register of Citizens (NRC) and the National Population Register (NPR).

Union home minister Amit Shah has said that the government won't rest until persecuted refugees are granted Indian citizenship.
