Senior Cong leaders are egoistic, inaccessible: Cadre complain to Rahul Gandhi

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.

Beijing, Feb 18: Police in China have arrested a prominent activist who had been a fugitive for weeks and criticised President Xi Jinping's handling of the coronavirus epidemic while in hiding, a rights group said Tuesday.

Anti-corruption activist Xu Zhiyong was arrested on Saturday after being on the run since December, according to Amnesty International.

China's ruling Communist Party has severely curtailed civil liberties since Xi took power in 2012, rounding up rights lawyers, labour activists and even Marxist students.

The death this month of a whistleblowing doctor who was reprimanded by police for raising the alarm about the deadly new virus before dying of it himself triggered rare calls for political reform and freedom of speech.

The "Chinese government's battle against the coronavirus has in no way diverted it from its ongoing general campaign to crush all dissenting voices," said Patrick Poon, China researcher at Amnesty International, in an emailed statement.

Another source, who spoke to news agency on the condition of anonymity, said Xu had been arrested in the southern city of Guangzhou.

Guangzhou police did not respond to requests for comment.

Xu went into hiding after authorities broke up a December gathering of intellectuals discussing political reform in the eastern coastal city of Xiamen in Fujian province, prior to the coronavirus crisis.

Over a dozen lawyers and activists were detained or disappeared after the Xiamen gathering, according to rights groups -- and Xu's detention appears linked to his presence at the meeting, explained Poon.

But while on the run, Xu continued to post information on Twitter about rights issues.

On February 4 Xu released an article calling on Xi to step down and criticised his leadership across a range of issues including the US-China trade war, Hong Kong's pro-democracy protests and the coronavirus epidemic, which has now killed nearly 1,900 people.

"Medical supplies are tight, hospitals are filled with patients, and a large number of infected people have no way to be diagnosed," he wrote. "It's a mess."

"The coronavirus outbreak shows just how important values like freedom of expression and transparency are -- the exact values that Xu has long advocated," Yaqiu Wang, China researcher at Human Rights Watch, told news agency.

But the disappearance of Xu illustrates how the Chinese state "persists in its old ways" by "silencing its critics", she said.

Xu -- who founded a movement calling for greater transparency among high-ranking officials -- previously served a four-year prison sentence from 2013 to 2017 for organising an "illegal gathering".

"That he was a fugitive for so many days while continuing to speak out, that in itself was... a kind of challenge to (Chinese authorities)," said Hua Ze, a long-time friend of Xu who told AFP she lost contact with the Chinese activist on Saturday morning.

New Delhi, Jul 16: India's pharmaceutical industry will be able to produce Covid-19 vaccines not just for the country but also for the entire world, according to Microsoft co-founder and philanthropist Bill Gates.

A lot of "very important things have been done" in India and its pharma industry is doing work "to help make the coronavirus vaccine building on other great capacities that they have used for other diseases", said the Co-Chair and Trustee of Bill and Melinda Gates Foundation.

Speaking in a documentary -- Covid-19: India's War Against The Virus -- to be premiered on Discovery Plus this (Thursday) evening, Gates said India also faces a huge challenge due to the health crisis because of its gigantic size and urban centres with a lot of population density.

Commenting on the strength of India's pharma industry, he said, "India has a lot of capacity there -- with the drug and vaccine companies that are huge suppliers to the entire world. You know, more vaccines are made in India than anywhere-- starting with Serum Institute, that's the largest."

He further said, "But (there are) also Bio E, Bharat (Biotech), many others. They are doing work to help make the coronavirus vaccine, building on other great capacities that they have used for other diseases."

Stating that India joined Coalition for Epidemic Preparedness Innovations (CEPI), which is a group working on a global basis to build vaccines platforms, Gates said, "I am excited that the pharmaceutical industry there will be able to produce not just for India but also for the entire world. (This is) What we need to reduce the deaths and make sure we are immune, which is how we end the epidemic."

Gates said Bill and Melinda Gates Foundation is also a "partner with the government, particularly with the department of biotechnology, the Indian Council of Medical Research (ICMR) and the office of the principal scientific advisor provide advice and help about getting these tools going".

Commenting on the deadly virus breaching India's borders in the documentary which was shot extensively during the period of lockdown, he said, "India is still at the beginning of this, but there's a lot of very important things have been done.

“It's a huge challenge with India because you've got a gigantic country. You've got your urban centers with a lot of density-- and so that-- drives the spread. You have people moving around."

He, however, added: "Yet people are stepping up... Looking at how we reduce the spread while trying not to reduce food availability, equipment that people need."

Highlighting Gates foundation's role, he said it has "worked for the Indian government on health issues like introducing new vaccines over the last decade; and so when Covid-19 came along, we stepped in and said you know where are the gaps, we have been funding work on detection and isolation.

“We have been particularly active in UP and Bihar where we have done health delivery in the past."

The foundation is also working with the department of personnel and training to take their online training platforms and "are now using that guidance to help their frontline health workers", Gates said.
