Poll results a clear message to BJP, it's time to introspect: Shiv 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.

More than 50 million people in India do not have access to effective handwashing, putting them at a greater risk of acquiring and transmitting the novel coronavirus, according to a study.

Researchers from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington in the US found that without access to soap and clean water, over 2 billion people in low- and middle-income nations -- a quarter of the world's population -- have a greater likelihood of transmitting the coronavirus than those in wealthy countries.

According to the study, published in the journal Environmental Health Perspectives, more than 50 per cent of the people in sub-Saharan Africa and Oceania lacked access to effective handwashing.

"Handwashing is one of the key measures to prevent COVID transmission, yet it is distressing that access is unavailable in many countries that also have limited health care capacity," said Michael Brauer, a professor at IHME.

The study found that in 46 countries, more than half of people lacked access to soap and clean water.

In India, Pakistan, China, Bangladesh, Nigeria, Ethiopia, Democratic Republic of the Congo, and Indonesia, more than 50 million persons in each country were estimated to be without handwashing access, according to the study.

"Temporary fixes, such as hand sanitizer or water trucks, are just that -- temporary fixes," Brauer said.

"But implementing long-term solutions is needed to protect against COVID and the more than 700,000 deaths each year due to poor handwashing access," Brauer said.

He noted that even with 25 per cent of the world's population lacking access to effective handwashing facilities, there have been "substantial improvements in many countries" between 1990 and 2019.

Those countries include Saudi Arabia, Morocco, Nepal, and Tanzania, which have improved their nations' sanitation, the researchers said.

The study does not estimate access to handwashing facilities in non-household settings such as schools, workplaces, health care facilities, and other public locations such as markets.

Earlier this month, the World Health Organization predicted 190,000 people in Africa could die of COVID-19 in the first year of the pandemic, and that upward of 44 million of the continent's 1.3 billion people could be infected with the coronavirus, the researchers said. 

Mumbai, Feb 5: Maharashtra Chief Minister Uddhav Thackeray on Wednesday said there was no need to fear the Citizenship Amendment Act, but asserted his government will not allow the proposed National Register of Citizens to be implemented as it would "impact people of all religions".

Throwing out Bangladeshi and Pakistani migrants out of the country was an old demand of the Shiv Sena, the chief minister said in the third and concluding part of his interview to party mouthpiece 'Saamana'.

"I can confidentally say the Citizenship (Amendment) Act (CAA) is not meant to throw Indian citizens out of the country. But, the National Register of Citizens (NRC) is going to impact Hindus as well," the Sena president said.

India has the right to know the number of minorities from neighbouring nations who applied for Indian citizenship after being persecuted in their home countries, he said.

"When they come here, will they get homes under the 'Pradhan Mantri Awas Yojana'? What about employment and education of their children? All these issues are important and we have the right to know," hesaid in the interview to Saamana's executive editor and Sena MP Sanjay Raut.

"As chief minister, I should know where will these people be relocated in my state. Our own people don't have adequate housing. Will these people go to Delhi, Bengaluru or Kashmir, since Article 370 is now scrapped?" he wondered.

Several Kashmiri Pandit families are staying like refugees in their own country. The CAA is not to throw citizens out of the country, Thackeray said.

"However, the NRC will impact Hindus and Muslims and the state government will not allow it to be implemented," he asserted.

Under the NRC, all citizens will have to prove their citizenship. In Assam, 19 lakh people could not prove their citizenship. Of these, 14 lakh are Hindus, Thackeray claimed.

In a veiled attack on his cousin and MNS chief Raj Thackeray, who will lead a rally in support of the CAA and NRC in Mumbai on February 9, the chief minister said the NRC is not yet a reality and there is no need for a 'morcha' in support of or against it.

"If the NRC is enforced, those who are supporting it will also be affected," he said.

Under the NRC, even Hindus will have to prove their citizenship. "I will not allow the law to be enacted. Whether I am chief minister or not, I will not allow injustice to anybody," he said.

The chief minister also took a veiled dig at the Centre's decision to give the Padma Shri award to Pakistani-origin musician Adnan Sami.

"A migrant is a migrant. You can't honour him with the Padma award. Throwing out illegal migrants was the stand of (late Shiv Sena supremo) Balasaheb Thackeray," he said without naming anyone.
