Kochi, Jan 11: Two of the four illegal apartment complexes were brought down by controlled implosion here on Saturday.

However, the other two apartments-- Golden Kayaloram and Jain Coral-- will be demolished on Sunday.

The demolition of the first building Holy Faith H2O, slated to be carried out at 11 am, was delayed by 18 minutes while the twin towers of Alfa Serene, which is surrounded by 36 houses, were brought down at 11.43 am.

As per authorities, as many as 343 kgs of explosives were used for the demolition of twin towers of Alfa Serene, which had 80 apartments and 16 floors each.

Section 144 has been imposed within a 200-metre radius of the complexes on Saturday and Sunday. Moreover, traffic has been halted on land, water and air in the evacuation zone during the process.

There are concerns that some concrete pieces of the second tower of the building may have fallen into the lake nearby. It is yet to be estimated if the debris or concrete pieces have affected the buildings nearby.

The four apartment complexes in Maradu were ordered to be demolished by the Supreme Court for violating the Coastal Regulation Zone (CRZ) norms.

Dehradun, Jan 6: Universities are centres of learning and will not be allowed to become "addas" of politics, HRD Minister Ramesh Pokhriyal 'Nishank' has said.

The minister was replying to questions from reporters in Haldwani on Sunday about protests against the amended Citizenship Act across university campuses.

"Universities are centres of learning where the country's future is in the making. We cannot let them become addas of politics," Nishank said.

He accused the opposition parties of trying to turn the universities into hotbeds of politics.

The new legislation passed by Parliament aims to grant citizenship to persecuted religious minorities from Pakistan, Bangladesh and Afghanistan who had taken refuge in India and there is nothing wrong in it, the Union Minister said

"When Pakistan was created, the population of religious minorities there stood at 22 per cent. Today it is a minuscule 3.7 per cent. Persecuted on the basis of their religion, they sought sanctuary in India. The CAA is meant only to grant them citizenship," he said.

Terming the law humanitarian, the minister said it was going to make no difference to the status of Muslims in India and wondered why the Congress was making such a hue and cry about it.

Nishank's press conference in Haldwani was part of the BJP's campaign to create awareness in favour of the amended Citizenship Act.

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.
