150 missing, toll could rise in Assam boat accident

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.

Guwahati, Feb 13: Hours after Assam's updated citizenship data disappeared from the website 'nrcassam.nic.in', an FIR was filed against a former NRC official for allegedly failing to submit the password to the sensitive document before quitting her job.

Talking to news agency on Thursday, NRC state coordinator Hitesh Dev Sarma said the complaint against former NRC project officer was filed under Official Secrets Act in Paltan Bazar police station here, as she "did not provide the password to the document, despite written reminders".

"She failed to surrender the password even after tendering her resignation on November 11 last year. She was a contractual employee and no longer authorised to hold the password, after quitting her job. An FIR has been filed against the former NRC project officer on Wednesday for violating the Official Secrets Act," he said.

Sarma also stated that the NRC office had written to her on several occasions for submitting the password, but did not get any response.

"We knew (she had resigned) and, therefore, sent several letters to her for handing over the password. But as she did not respond all these months, we filed a complaint against her yesterday for violating the Official Secrets Act.

"We must know if she has tampered with the sensitive information, after resigning," he added. The NRC state coordinator, however, refuted allegations of "malafide intent" involved in the matter.

"...this (cloud service provided by IT major Wipro) was not renewed by the earlier coordinator. So, the data went offline from December 15 last year. I assumed charge only on December 24," Sarma, who had gone on leave for a weeks after being appointed as the NRC state coordinator, clarified.

He also said that the state coordination committee had discussed the issue in its meeting on January 30 and wrote to Wipro during the first week of February.

"Once Wipro makes the data live, it will be available to the public. We hope that people will be able to access it in the next 2-3 days," Sarma claimed.

Reacting to the development, Wipro had said: "The IT Services Contract was not renewed by the authorities upon its expiry in October, 2019. However, as a gesture of goodwill, the company continued to pay the hosting service fee until January-end, 2020."

In another FIR filed with state criminal investigation department on Wednesday, NGO Assam Public Works (APW) alleged that former NRC Assam coordinator Prateek Hajela tampered with the final NRC list - published on August 31, 2019.

APW member Rajib Deka, in his complaint, accused Hajela of disobeying orders and directions of the Supreme Court, forgery of public register and committed offences under cyber laws for altering or changing public records by misusing his powers and position.

The NGO also said that after publication of the final list, several social networks and sections of the media had reported anomalies, insisting that many 'doubtful' persons were able to insert their names in the final list.

The Centre on Wednesday asserted that NRC data in Assam was safe even though some technical issues have been detected, which would be resolved soon.

Senior journalist-cum-RTI activist Saket Gokhale had sent an application to the NIC, the IT wing of the government, seeking a copy of the contract with Wipro.

"The Assam NRC data suddenly vanishing from the website (& the lack of data security) is incredibly shady. I've filed an RTI with the NIC specifically asking about details of the contract with Wipro, name of the cloud service provider, & all contracts signed for hosting this," he tweeted, while attaching a copy of the RTI application.

Leader of the Opposition in Assam Assembly and Congress leader Debabrata Saikia has also written to the Registrar General of India, requesting him to look into the fiasco urgently.

"It is a mystery as to why the online data should vanish all of a sudden, especially as the process to file appeals was yet to begin, all because of the go-slow attitude adopted by the NRC Authority. There is, therefore, ample scope to suspect that disappearance of online data is a malafide act," he had insisted.

United Nations, Jun 6: The coronavirus disease has not "exploded" in India, but the risk of that happening remains as the country moves towards unlocking its nationwide lockdown that was imposed in March to contain the Covid-19, according to a top WHO expert.

WHO Health Emergencies Programme Executive Director Michael Ryan on Friday said the doubling time of the coronavirus cases in India is about three weeks at this stage.

“So the direction of travel of the epidemic is not exponential but it is still growing,” he said, adding that the impact of the pandemic is different in different parts of India and varies between urban and rural settings.

“In South Asia, not just in India but in Bangladesh and...in Pakistan, other countries in South Asia, with large dense populations, the disease has not exploded. But there is always the risk of that happening,” Ryan said in Geneva.

He stressed that as the disease generates and creates a foothold in communities, it can accelerate at any time as has been seen in a number of settings.

Ryan noted that measures taken in India such as the nationwide lockdown have had an impact in slowing transmission but the risk of an increase in cases looms as the country opens up.

“The measures taken in India certainly had an impact in dampening transmission and as India, as in other large countries, open up and as people begin to move again, there's always a risk of the disease bouncing back up,” he said.

He added that there are specific issues in India regarding the large amount of migration, the dense populations in the urban environment and the fact that many workers have no choice but to go to work every day.

India went past Italy 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.

The lockdown in India, was first clamped on March 25 and spanned for 21 days, while the second phase of the curbs began on April 15 and stretched for 19 days till May 3. The third phase of the lockdown was in effect for 14 days and ended on May 17. The fourth phase ended on May 31.

The country had registered 512 coronavirus infection cases till March 24.

The nation-wide lockdown in containment zones will continue till June 30 in India but extensive relaxations in a phased manner from June 8 are listed in the Union home ministry's fresh guidelines on tackling the Covid-19 pandemic issued last week.

WHO Chief Scientist Soumya Swaminathan said the over 200,000 current coronavirus cases in India, a country of over 1.3 billion people, "look big but for a country of this size, it's still modest.”

She stressed that it is important for India to keep track of the growth rate, the doubling time of the virus and to make sure that that number doesn't get worse.

She said that India is a “heterogeneous and huge country” with very densely populated cities and much lower density in some rural areas and varying health systems in different states and these offer challenges to the control of Covid-19.

Swaminathan added that as the lockdown and restrictions are lifted, it must be ensured that all precautions are taken by people.

“We've been making this point repeatedly that really if you want behaviour change at a large level, people need to understand the rationale for asking them to do certain things (such as) wearing masks,” she said.

In many urban areas in India, it's impossible to maintain physical distancing, she said adding that it then becomes very important for people to wear appropriate face coverings when they are out, in office settings, in public transport and educational institutions.

“As some states are thinking about opening, every institution, organisation, industry and sector needs to think about what are the measures that need to be put in place before you can allow a functioning and it may never be back to normal.”

She said that in many professions working from home can be encouraged but in several jobs, people have to go to work and in such cases measures must be put in place that allow people to protect themselves and others.

“I think communication and behaviour change is a very large part of this whole exercise,” she added.
