Yogi is angry as Rahul plans to visit tragedy-hit Gorakhpur

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.

Kolkata, Jan 1: US-based Bangladeshi author and playwright Sharbari Zohra Ahmed feels that the people of the country of her origin are more alike than different from Indians as they were originally Hindus.

But Bangladeshis now want to forget their Hindu roots, said the author, who was born in Dhaka and moved to the United States when she was just three weeks old.

Ahmed, who is the co-writer of the Season 1 of 'Quantico', a popular American television drama thriller series starring Priyanka Chopra, rues that her identity as a Bengali is getting lost in Bangladesh due to the influence of right-wing religious groups.

"How can Bangladesh deny its Hindu heritage? We were originally Hindus. Islam came later," Ahmed said while speaking to PTI here recently.

"The British exploited us, stole from us and murdered us," she said about undivided India, adding that the colonialists destroyed the thriving Muslin industry in Dhaka.

Ahmed said the question of her belief and identity in Bangladesh, where the state religion is Islam, has prompted her to write her debut novel 'Dust Under Her Feet'.

The British exploitation of India and the country's partition based on religion has also featured in her novel in a big way.

Ahmed calls Winston Churchill, the British prime minister during World War II, a "racist".

"He took the rice from Bengal to feed his soldiers and didn't care when he was told about that.

"During my research, I learnt that two million Bengalis died in the artificial famine that was created by him. When people praise Churchill, it is like praising Hitler to the Jews. He was horrible," she said.

The author said her novel is an effort to tell the readers what actually happened.

"Great Britain owes us three trillion dollars. You have to put in inflation. Yet, they (the British) still have a colonial mentality and white colonisation is on the rise again," Ahmed, who was in the city to promote her novel, said.

The novel is based in Kolkata, then Calcutta, during World War II when American soldiers were coming to the city in large numbers.

The irony was that while these American soldiers were nice to the locals, they used to segregate the so-called "black" soldiers, the novelist said.

"Calcutta was a cosmopolitan and the rest of the world needs to know how the city's people were exploited, its treasures looted, people divided and hatred instilled in them," she said.

"Kolkata was my choice of place for my debut novel since my mother was born here. She witnessed the 'Direct Action Day' when she was a kid and was traumatised. She saw how a Hindu was killed by Muslims near her home in Park Circus area (in the city)," Ahmed said.

Direct Action Day, also known as the Great Calcutta Killings, was a massive communal riot in the city on August 16, 1946 that continued for the next few days.

Thousands of people were killed in the violence that ultimately paved the way for the partition of India.

'Dust Under Her Feet' is set in the Calcutta of the 1940s and Ahmed in her novel examines the inequities wrought by racism and colonialism.

The story is of young and lovely Yasmine Khan, a doyenne of the nightclub scene in Calcutta.

When the US sets up a large army base in the city to fight the Japanese in Burma, Yasmine spots an opportunity.

The nightclub is where Yasmine builds a family of singers, dancers, waifs and strays.

Every night, the smoke-filled club swarms with soldiers eager to watch her girls dance and sing.

Yasmine meets American soldier Lt Edward Lafaver in the club and for all her cynicism, finds herself falling helplessly for a married man who she is sure will never choose her over his wife.

Outside, the city lives in constant fear of Japanese bombardment at night. An attack and a betrayal test Yasmine's strength and sense of control and her relationship with Edward.

Ahmed teaches creative writing in the MFA program in Manhattanville College and is artist-in-residence in Sacred Heart University's graduate film and television programme.

May 28: Congress President Sonia Gandhi on Thursday asked the central government to unlock its coffers and help the needy affected by the coronavirus-induced lockdown.

In a video message posted as part of the Congress' 'Speak Up India' campaign, she lamented that even though the country is passing through a serious economic crisis with loss of livelihood due to the pandemic and the lockdown, the central government has not heard the cries of pain and trauma of people.

"We again urge the Centre to unlock its coffers and help the needy. Put direct cash of Rs 7,500 per month in the account of every family for the next six months and provide Rs 10,000 immediately; ensure safe and free travel of labourers back home, employment opportunity and rations; and also increase the number of work days under MNREGA to 200 days to facilitate jobs in villages," Gandhi said.

"Instead of loans, provide financial relief to small and medium industry so that crores of jobs are saved and the country progresses," she said in her video message on the party's social media handles.
