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 30: In a major shift of strategy ahead of the Delhi assembly polls, the Bharatiya Janata Party (BJP) has decided to rope in its senior leaders for massive public rallies.

Its star campaigners like Prime Minister Narendra Modi, Union Home Minister Amit Shah, BJP chief JP Nadda, Uttar Pradesh Chief Minister Yogi Adityanath, and other union ministers would now be addressing massive public rallies in addition to ongoing neighbourhood meetings.

"The big rallies would begin from February 1. While 'Nukkad' meetings will take place till the last day of campaigning, there would be big rallies of the top leadership of the party, " informed a senior party leader.

Sources said the BJP has changed its strategy after the success of its grassroots contact programme as the party wants to consolidate its gains.

"As part of the reworked strategy the BJP has asked its various Mandals to organise public meetings of 10,000-15,000 people in each assembly segment to reach out to the masses," sources added.

While there are two planned for Prime Minister Modi, two have been planned for JDU chief and Bihar Chief Minister Nitish Kumar along with Nadda and Amit Shah. Yogi Aadityanath too would be addressing 12 rallies.

The party is leaving no stone unturned to secure massive gains, which it feels can be converted to victory in the forthcoming polls.

Party sources feel that the relentless campaigning under the guidance of Amit Shah and Nadda has ensured that the morale of party cadre is at an all-time high.

"The neighbourhood meetings have ensured that we have been able to make the people of Delhi aware of the lack of work under the Arvind Kejriwal led Aam Aadmi Party government. They have also been apprised about the anti-national views of the opponents and we think that this is expected to turn the polls into our favour," sources added.

Delhi is scheduled for assembly polls on February 8 and the results for the 70 constituencies will be declared on February 11.

As part of the new strategy, senior leaders like JP Nadda, Amit Shah, Uttar Pradesh chief minister Yogi Adityanath, ministers like Rajnath Singh and Smriti Irani would be holding public rallies in various parts of the city. Several other chief ministers from various BJP ruled states are also expected to be roped in for the campaign.

The strategy for reach out to the masses is an attempt at weakening the hold of AAP on Delhi. With positive feedback coming after the success of the neighbourhood meetings in the past week, the BJP is now looking to increase its potential reach with polls just days away.

Till now the party had deployed 70 union ministers to hold at least one public meeting and one 'padayatra' each as part of the campaign.

New Delhi, Jul 20: Reiterating that China has still occupied India's territory, Congress leader Rahul Gandhi on Monday attacked Prime Minister Narendra Modi saying that he has fabricated a fake strongman image to come to power which has now become India's biggest weakness as he has to protect the idea of 'Chhapan Inch'.

Taking to Twitter, the Congress leader posted a video message and wrote, "PM fabricated a fake strongman image to come to power. It was his biggest strength. It is now India's biggest weakness."

In the video message, speaking on "China's Strategic Game Plan" the Congress leader said: "What is China's strategic and tactical game plan? It is simply not a border issue. The worry I have is that the Chinese are sitting in our territory today. Chinese don't do anything without thinking about it strategically."

"In their mind, they have mapped out the world and they are trying to shape the world. That's the scale of what they are doing. That's what Gwadar is, that is what belt and road is. It is a restructuring of the planet. So when you are thinking about the Chinese you have to understand that that is the level at which they are thinking," he added.

Now at the tactical level, they're trying to improve their position. Whether it is Galwan, whether it's Demchok or whether it is Pangong Lake. The idea is to position themselves, he said.

"They are disturbed by our highway they want to make our highway redundant and if they are thinking larger scale, they want to do something with Pakistan in Kashmir. So it is not simply a border issue. It is a border issue designed to put pressure on the Prime Minister of India," the Congress leader said.

"And they are thinking of putting pressure in a very particular way. And what they are doing, is that they are attacking his image. They understand that it in order for Mr Narendra Modi to be an effective politician; in order for Mr Narendra Modi to survive as a politician, he has to protect the idea of--Chhapan Inch. And this the real idea the Chinese are attacking. They are basically telling Mr Narendra Modi that if you do not do what we say, we will destroy the idea of Mr Narendra Modi as a strong leader," he added.

Gandhi continued saying, now the question is, how will PM Narendra Modi react. Will he take them on? Will he take on the challenge and say absolutely not, I'm the Prime Minister of India. I do not care about my image I'm going to take you on. Or will he succumb to them?

"The worry I have so far is that the Prime Minister has succumbed. The worry I have is, the Chinese are sitting in our territory today and the Prime Minister has said publicly they are not, which to me tells me that is worried about his image and defending his image," said Gandhi.

"And if he allows the Chinese to understand that they can manipulate him because of his image, the Indian Prime Minister will no longer be worth anything for India," he added.
