Kerala to object state banker’s committee’s recovery procedures on farmer loans

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, Apr 28: With 1,594 new cases of COVID-19 reported in the last 24 hours and 51 deaths, India's total count of coronavirus cases surged to 29,974, said the Union Ministry of Health and Family Welfare on Tuesday.

The total cases are inclusive of 7,026 cured and discharged patients, one migrated and 937 deaths.

At present, there are 22,010 active COVID-19 cases in the country.

Addressing a press conference here, Lav Agarwal, Joint Secretary, Union Health and Family Welfare Ministry, said that in the last 28 days, 17 districts have had no new Covid-19 cases. "This means we need to maintain constant vigil," he added.

Thiruvananthapuram, Jan 25: Kerala Chief Minister Pinarayi Vijayan on Friday asked the state's MPs to take up the matter of deaths of eight Keralites at a resort in Nepal early this week, with the Centre to pursue the matter with the neighbouring country's government.

He was speaking to the MPs at the customary meeting that the Chief Minister has with all MPs ahead of every session of the parliament.

"The demand has come from the families of the victims for a fair probe on what happened and adequate compensation. For this, you (MPs) should take it up with the Centre. A probe has to be done by the Nepal authorities and the Centre should pursue this with them," Pinarayi reportedly stated. 

"We (the state government) have already taken the issue with the Centre and will now send a detailed letter on the need for a fair probe by the Nepal authorities," he added.

The eight dead include Praveen Krishnan Nair, who worked in the UAE and was on a short vacation here, when the tragedy struck the family. His wife Saranya, a second year M.Pharma student, and their three children, were also killed.

On Friday morning, it was a goodbye that Thiruvananthapuram has perhaps not seen before, as hundreds of people, many of them strangers, came to pay last respects to the five members of the Nair family.

The family of Praveen Nair decided to bury the bodies of the three children and cremate the bodies of Praveen and Saranya. It was also decided to bury the ashes of the couple alongside their three children in the compound of their house.

The second family hailed from Kozhikode and the bodies of Ranjith, an IT professional, his wife, who works in a cooperative bank and their younger child, who slept in the same room as that of Praveen, arrived at the Kozhikode airport on Friday morning.

State Transport Minister A.K. Saseendran and many others were there to receive the bodies, which were first taken to Ranjith's new home that is almost complete.

From there it was taken to a hall for all to pay their last respects and then to the family home of Ranjith where the cremation took place.

Watching everything happening was Ranjith's elder son, seven-year-old Madhav, who escaped that night in Nepal as he was sleeping in another room.

Madhav had arrived from Delhi on Thursday and was unaware of the tragedy as he was busy moving around in a new bicycle, which his relatives had bought to keep him busy.
