Minorities feel safe under PM Narendra Modi, will vote for him: Shahnawaz Hussain

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 23: With an increase of 14,933 new cases and 312 deaths in the last 24 hours, India's COVID-19 count reached 4,40,215 on Tuesday.

According to the latest update by the Union Ministry of Health and Family Welfare (MoHFW), 14,011 deaths have been recorded due to the infection so far in the country.

The rise in confirmed cases today is lower than the highest spike of 15 thousand plus cases registered on Sunday.

The count includes 1,78,014 active cases, and 2,48,190 cured/discharged/migrated patients.

Maharashtra with 1,35,796 confirmed cases remains the worst-affected by the infection so far in the country. The state's count includes 61,807 active, 67,706 cured, discharged patients while 6,283 deaths have been reported due to the infection so far.

Meanwhile, the national capital's confirmed coronavirus cases reached 62,655.

2,233 deaths have been reported in Delhi due to the infection so far.

Tamil Nadu has reported 62,087 cases so far with toll increased to 794.

Bhopal, Mar 15: Madhya Pradesh Chief Minister Kamal Nath on Saturday sought the intervention of Home Minister Amit Shah for the "release" of 22 Congress MLAs in Karnataka, saying they had been held "captive" and were under "pressure".

In a letter to Shah, Chief Minister Nath said the BJP's demand for floor test had "no meaning" till the MLAs do not reach the state.

He said that the MLAs do not have any means of personal communication and all efforts to reach them have failed.

In the four-page letter, Nath said Governor Lalji Tandon had told him that the responsibility of security of those who will come to meet the Speaker should be with the CRPF but as the Chief Minister, it is his duty to ensure the security of all residents of the state including MLAs.

"I assure you that if these 22 MLAs are released by the Karnataka Police, then I will ensure maximum security by the state government so that they are able to convey their views without fear and take part in the proceedings of the assembly," Nath said.

He urged Shah to use his powers as Home Minister so that 22 MLAs safely reach Madhya Pradesh and discharge their responsibilities "without fear or greed" in the assembly session beginning on March 16."

Chief Minister Nath said that he had been informed that the MLAs had been deprived of all personal communication facilities.

He said that a father was not allowed to meet his son and two ministers who were accompanying the father of the legislator were "arrested" and manhandled by the Karnataka Police.

"My efforts to reach them as also of their relatives have failed which proves my apprehension that they are under captivity."

He said the videos released in the name of MLAs to "mislead" the people of the state were similar. "This proves that all these MLAs are under pressure and they are being forced to act in a particular way," he said.

Nath said that he was drawing Shah's attention to the developments in the state since March 3 which were aimed at destabalising the government.

He said three Congress MLAs, one BSP, and one independent MLA were taken to Gurugram and two ministers of his government were able to "rescue" the BSP legislator.

He said the three Congress MLAs and the independent MLA were later taken to Bengaluru by the BJP. He said a BJP MLA and a party functionary accompanied them.

"Later, 19 Congress MLAs were taken to Bengaluru in chartered planes and the arrangement was done by the BJP," he said, adding that they were accompanied by two former BJP MLAs and a former minister.

Kamal Nath said the number of MLAs in Bengaluru grew to 22 and they are all in the protection of the Karnataka Police.

He said some BJP leaders from Madhya Pradesh can be seen in pictures of the place where the MLAs were staying. "All reported expenses on these MLAs are being borne by the BJP," he said.

He said the BJP leaders had told the media about the resignation of MLAs and they had not presented themselves before the assembly Speaker.

Kamal Nath said he was concerned about the security of the MLAs and had written to the Governor earlier.

"You would agree with me that the demand for floor test has no meaning till the 22 MLAs are in captivity. This is unprecedented that the BJP is demanding floor test and several Congress MLAs have been kept outside the state,' he said.
