Poll schedule for five states announced, UP votes in 7 phases

New Delhi, Feb 18: Election strategist-turned-politician Prashant Kishor on Tuesday questioned the Nitish Kumar government's development model, even as he sneered at the chief minister for making ideological compromises to stay in an alliance with the BJP.

Kishor, who has been vocal about his opposition to the Citizenship (Amendment) Act (CAA), said Kumar needs to spell out whether he is with the ideals of Mahatma Gandhi or those who support Nathu Ram Godse.

"Nitish ji has always said that he cannot leave the ideals of Gandhi, JP and Lohiya... At the same time, how can he be with the people who support the ideology of Godse? Both cannot go together. If you want to stay with the BJP, I don't have any problem with it but you cannot be on both sides," he said.

"There has been a lot of discussion between me and Nitish-ji on this. He has his thought process and I have mine. There have been differences between him and me that the ideologies of Godse and Gandhi cannot stand together. As the leader of the party you have to say which side you are on," he added.

In a direct assault on Kumar's model of governance, Kishor said Bihar was the poorest state in 2005 and continues to be so.

"There has been development in Bihar during the last 15 years, but the pace has not been as it should have," he added.

New Delhi, Jun 13: India's COVID-19 tally on Saturday witnessed its highest-ever spike of 11,458 cases, according to the Union Ministry of Health and Family Welfare (MoHFW).

A total of 386 deaths have been reported due to the infection during the last 24 hours.

The total number of coronavirus cases in the country now stands at 3,08,993 including 1,45,779 active cases 1,54,330 cured/discharged/migrated and 8,884 deaths.

COVID-19 cases in Maharashtra continue to soar with the number reaching 101141. Tamil Nadu's coronavirus count stands at 40,698 while cases in Delhi reached 36,824.

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.
