Parties back promotion quota for dalits; SP dissents

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, Jun 5: Around 20 staff members of Delhi Metro Rail Corporation (DMRC) have tested positive for COVID-19, all of them are asymptomatic and are doing well, said DMRC officials.

In a statement, the DMRC said, "Along with the rest of the country, DMRC is also fighting the battle against COVID-19. Delhi Metro's employees have shown exemplary resilience in reporting back to their duties to keep the Metro system in all readiness for the eventual resumption of services."

"Some employees, scattered across the NCR have unfortunately been infected by the virus as well. They are all safe and recovering gradually. However, in this hour of crisis as well, the spirit of Delhi Metro continues to be high," the DMRC stated.

DMRC Managing Director, Dr Mangu Singh, in a message today asked all employees to adhere to social distancing norms and wished those afflicted with the virus a speedy recovery.

"This indomitable spirit will surely help the Delhi Metro, whenever we resume our services in the days ahead," said DMRC.

Jaipur, Jul 13: Congress Legislature Party (CLP) on Monday unanimously passed a resolution supporting Chief Minister Ashok Gehlot-led government and accusing the BJP of destabilising the government by indulging in horse-trading of MLAs.

The CLP also condemned all "undemocratic" acts to weaken Congress party and its government and demanded action against any Congress office-bearers involved in anti-party activities.

"Feared by exemplary works and public service of Congress government, BJP-led conspiracy is trying to destabilise Congress' state government, horse-trading of MLAs and trying to murder democracy by using money and political power," read the resolution.

"It is unfortunate that BJP did not learn lessons from the defeat in the Rajya Sabha elections and are trying to destabilise Congress government using corrupt means. 

This ripping off of democracy by BJP is an insult to 8 crore people of Rajasthan, they will not accept it. CLP meet expresses its confidence in Congress President Sonia Gandhi and leader Rahul Gandhi, and unanimously supports the government led by Ashok Gehlot," it said.

"This meet urges that strict disciplinary action be taken against any office-bearer or member of Legislative Party who indulges in activities against the Congress government, party or gets involved in any conspiracy," read the resolution.

As many as 107 MLAs attended the CLP meeting, which begun in the afternoon and now has been concluded.

"107 MLAs are present at the CLP meeting in Jaipur," Chief Minister Ashok Gehlot's media advisor confirmed to media.

The crisis in Rajasthan Congress intensified with Gehlot and his deputy Sachin Pilot at loggerheads. While Gehlot is blaming BJP for trying to destabilise the state government by poaching MLAs, Pilot is camping in Delhi to speak to the party leadership regarding the political turmoil in the state.

BJP has claimed that the Ashok Gehlot-led government has lost the majority in the state.

"Sachin Pilot was the rightful candidate for the post of Rajasthan Chief Minister but Ashok Gehlot took the charge; a conflict in the party began since then. What is happening today is the result of that conflict. The state government has lost the majority," Rajasthan BJP President Satish Punia said today.
