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, Jan 5: A masked mob on Sunday entered the Sabarmati Hostel on the Jawaharlal Nehru University (JNU) campus and assaulted several students and professors with sticks and rods.

"I have been brutally attacked by goons wearing masks. I am bleeding. I was brutally beaten up," JNU Students' Union (JNUSU) president Aishe Ghosh told reporters.

She has been admitted to the AIIMS here for treatment.

Several other students were also injured in the incident.

In a video of the incident, a group of goons with their faces covered can be seen assaulting students with wooden sticks and rods.

A tweet from the official handle of the JNUSU said, "Sabarmati Hostel: right now. They are beating the students who are inside. Knocking on doors with rods. People are jumping from balconies. #SOSJNU #EmergencyinJNU."

"Professors who were trying to protect us have been beaten up. These are unknown ABVP goons, not all are students, they have covered their faces, and they are moving towards the hotels near the West Gate. Stay alert. Make human chains. Protect each other. #SOSJNU #EmergencyinJNU," another tweet added.

Meanwhile, the ABVP's JNU unit claimed in a tweet: "Emergency in JNU. Leftist goons of JNU accompained with their cadre from other universities have crossed every limit. They have proceeded with unimaginable violence on ABVP activists of JNU."

Lucknow, May 27: Uttar Pradesh chief minister Yogi Adityanath has taken a U-turn, two days after he declared that permission would be needed if other states employ workers from UP.

The issue sparked a major controversy and an official spokesman has now said that the government would not include this clause of 'prior permission' in the bye-laws of the Migration Commission.

The government spokesman also said it was working on modalities to set up the commission to provide jobs and social security to migrant workers returning to the state. It has named the migration commission as the "Shramik Kalyan Aayog (Workers welfare commission).

About 26 lakh migrants have already returned to the state and an exercise to map their skills is being carried out to help them get jobs.

Yogi Adityanath has discussed the modalities for setting up the commission and told his officers to complete the skill mapping exercise in 15 days.

A senior official of Team 11, said, "The chief minister discussed the modalities for setting up the commission, as well. There will be no provision requiring other states to seek UP government's prior permission for employing our manpower. The commission is being set up to provide jobs and social security to the workers. We will also link the migrants to the government schemes to provide them houses and loans etc."

Yogi Adityanath said a letter should be sent to all state governments to find out about migrant workers wanting to come back to Uttar Pradesh.

Earlier, the chief minister, while speaking at a webinar on Sunday, had said, "The migration commission will work in the interest of migrant workers. If any other state wants UP's manpower, they cannot take them just like that, but will have to seek permission of the UP government. The way our migrant workers were ill-treated in other states, the UP government will take their insurance, social security in its hands now. The state government will stand by them wherever they work, whether in Uttar Pradesh, other states or other countries."

The statement had sparked a row with some political leaders and parties questioning the move.

Former Congress president Rahul Gandhi sharply criticized Adityanath's stand, saying the workers were not the chief minister's personal property.

"It is very unfortunate that the chief minister of Uttar Pradesh views India in such a way. These people are not his personal property. They are not the personal property of Uttar Pradesh. These people are Indian citizens and they have the right to decide what they want to do and they have the right to live the life they want to live," he had said.

Maharashtra Navnirman Sena chief Raj Thackeray had also taken on Adityanath and said that if UP insists on "permission" before other states can employ workers from there, "then any migrant entering Maharashtra would need to take permissions from us, from the Maharashtra state, our police force too."

Meanwhile, the government spokesman said, "The chief minister is deeply moved by the condition of migrants. They have been treated badly by other states. So, when the chief minister spoke about the need for seeking UP government's permission, he did so as a guardian for workers. It's only his concern for the migrants that came out as a political statement."
