India No. 3 in world in realty price rise

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.

Kochi, Jan 22: The Left front government in Kerala on Monday decided to inform the Centre it would not cooperate with the updation of the NPR, saying there were fears among the public about the process and it has the "Constitutional responsibility" to alleviate them and ensure law and order.

A special cabinet meeting, chaired by Chief Minister Pinarayi Vijayan here, decided to inform the Registrar General and Census Commissioner under the Union Home Ministry that it was unable to cooperate with anything with regard to the updation of the NPR.

"The decision was taken as it was the Constitutional responsibility of the government to alleviate the fears of general public and ensure law and order situation in the state," a Chief Minister's Office release said.

However, the state would fully cooperate with the census procedures, it said.

The LDF government, which has been on a warpath against the Centre over the Citizenship Amendment Act, has last month stayed all activities related to updation of NPR, considering 'apprehensions' of public that it would lead to NRC in the wake of the controversial CAA.

"As the NPR is a process that leads to the National Register of Citizens (NRC), there is a sense of fear among the people that its implementation could lead to widespread insecurity", the CMO release said on Monday.

The experience of the state which had already compiled the NRC was an example for this, it added, in apparent reference to Assam.

Kerala had already stopped all procedures regarding the NPR updation, the release said adding there was also a report of the state police that the if the government went ahead with the procedures, it would adversely impact the law and order situation.

The district collectors have also informed the government that the Census procedures would be affected if the updation of the NPR was done along with it, the CMO release said.

The CPI(M)-led LDF government had recently convened a meeting of political parties and socio-religious organisations here on December 29 in the wake of the concerns among people in various stratas of the society, it said.

A special assembly session was convened and a resolution was passed requesting the Centre not to implement the CAA and the government had also approached the apex court against the law, it added.

New Delhi, Feb 29: Former RBI governor Raghuram Rajan has said slowdown in growth is due to the current government focussing more on meeting its political and social agenda rather than paying attention to the economy.

India can still reverse its slowing economic growth by paying attention to key issues, he said. "It's a sad story, I think most recently, it is politics," Rajan said in response to a question on what was stopping India's growth which remains below potential.

In an interview to Bloomberg TV, Rajan said unfortunately the current government after a massive election win has "focussed more on fulfilling its political and social agenda rather than paying attention to the economic growth".

"Unfortunately, this drift has continued a pace of slowing growth, which was precipitated initially by some actions the government took such as the demonetisation and a poorly rolled out Goods and Services Tax (GST) reform," Rajan said.

India's GDP growth hit nearly 7-year low of 4.7 per cent in the December quarter, as per official data released on Friday.

The GDP growth for the quarter is the lowest since January-March of 2012-13.

In the interview, which was telecast before the official numbers were released, Rajan said India has not paid sufficient attention to cleaning up the financial sector and unfortunately, that is leading to the slowing growth.

"These are things that they can change if attention is paid to them and appropriate actions are taken," Rajan, Professor of Finance at University of Chicago Booth School of Business, said.

On being asked about the spread of the coronavirus globally and its impact, he said there will certainly be some legacy issues in terms of business rethinking in the global supply chain.

"If it is disrupted anywhere, the entire supply chain is held ransom and companies are going to start rethinking that should we actually have these really spread out global supply chain or to bring them back closer home and how much diversification should we have. Should we have multiple production sites across the world rather than have it focussed primarily in Asia," he said.
