Outrage over diktats: No jeans for girls in Bhiwani college, no black dress at CM's Bijnor event

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, Apr 24: The Jamia Coordination Committee (JCC) on Friday accused Delhi Police of framing two of its members - Meeran Haider, Safoora Zargar, along with student leader Umar Khalid, as part of "an imaginary conspiracy behind the recent North East Delhi riots".

While Haider was arrested on April 2, Zargar was taken in custody on April 10 for their alleged involvement in fuelling the riots.

"These arrests by the police have little ground, and the charges seem to have no rhyme or reason. Safoora was even granted bail in the case she was initially arrested in, following which she was arrested and had heavier charges placed against her," the JCC said in a statement.

Meeran, Safoora and Umar have been charged under the Unlawful Activities (Prevention) Act (UAPA), which allows curbing of fundamental rights in order to protect the sovereignty of India. The JCC, however, claimed that in this case, the Act is being used to suppress their voices.

"This Act has been used against many activists working to protect constitutional morality, a list which now includes members of the JCC, a wholly constitutionalist collective of students and alumni," the JCC said, defending its members.

JCC maintained it had no role in Delhi riots, but apprehended that more people will be arrested by the Delhi Police as part of its conspiracy against students and protestors.

"It is almost certain that more protesters will be framed and arrested in the conspiracy invented by the Delhi Police. JCC reiterates that it played no part in the riots, and this fact will be proved before any court of law," it said in a statement.

It also demanded political parties, and university administration take a stand for the two accused JCC members and student leader Umar Khalid.

The JCC came into existence after a violent face-off between Delhi Police and unruly anti-CAA protestors left Jamia Millia Islamia vandalised. It was after this, that a group of students from the Jamia Millia formed it to decide upon the future course of actions in protest against the CAA and the police action.

May 7: Two people, including a child, were killed and nearly 70 hospitalised after a gas leak at a chemical plant in Andhra Pradesh's Visakhapatnam in the wee hours of Thursday, officials said.

People in Gopalapatnam area, where the chemical plant, LG Polymers, is located, complained of irritation in eyes, breathlessness, nausea and rashes on their bodies.

District Collector V Vinay Chand said two people were killed due to the gas leak, while some are in a critical condition.

Close to 70 people have been admitted to the King George Hospital after for treatment, he said.

TV channels showed people lying unconscious on roads.

Teams of the National Disaster Response Force (NDRF) have rushed to the spot.

Reports said the gas leak has been contained.

Chief Minister Y S Jagan Mohan Reddy enquired about the incident and directed the Visakhapatnam district collector to ensure proper medical care for the affected people.
