New Delhi, May 2: With 2,293 new cases in the last 24 hours, the highest number of cases in a single day, India's COVID-19 tally reached 37,336 on Saturday, including 1,218 deaths, according to the Ministry of Health and Family Welfare.
As many as 71 deaths were reported in the last 24 hours.

Out of the total number, 9,951 people have been cured/discharged/migrated.

In the state of Maharashtra, the number of coronavirus positive cases has crossed the 10,000-mark with at least 485 deaths.

The positive cases in Maharashtra has reached 11,506, including 1,879 discharged cases.

After Maharashtra, Gujarat has the most number of COVID-19 cases (4,721). The state has reported 236 deaths, while 735 people have been discharged.

The Centre on Friday extended the ongoing nationwide lockdown for two more weeks with effect from May 4 till May 17 while allowing different sets of relaxations in red, orange and green zones.

New Delhi, May 6: Taking a cue from states, the Centre announced one of the steepest hikes in duties on petrol and diesel in the recent past, by raising it by Rs 10 and Rs 13 per litre, respectively, in a notification issued late on Tuesday.

Retail prices, however, will see no change as the price hike will be absorbed by oil marketing companies against the fall in crude prices.

Road and infrastructure cess was hiked by Rs 8 for petrol and diesel and the special additional excise duty (SAED) was hiked by Rs 2 per litre and Rs 5 per litre, respectively. While the road cess will only go into the Centre’s coffers, the hike on account of SAED will be passed on to states via devolution at 42 per cent. Hence, the states will get only Rs 0.84 per litre in case of petrol and Rs 2.1 in case of diesel.

The decision comes after several states increased the value added tax (VAT) on petrol and diesel making use of the lower price regime. The Delhi government on Tuesday increased VAT on petrol and diesel to 30 per cent each, from 27 and 16.75, respectively. As a result, the price of petrol in Delhi increased by Rs 1.67 to Rs 71.26 a litre and diesel by Rs 7.10 to Rs 69.29 in Delhi on Tuesday.

Amid falling international crude oil prices, the Centre introduced an enabling provision in March to raise excise duty on petrol and diesel by Rs 8 per litre in the Finance Act. The government had on March 14 raised excise duty on petrol and diesel by? 3 per litre each, which was to help raise an additional ?39,000 crore in revenue annually.

This duty hike included Rs 2 a litre increase in SAED and Rs 1 in road and infrastructure cess. It raised SAED to Rs 10 for petrol and Rs 4 for diesel. The limit has now been increased to Rs 18 a litre in case of petrol and Rs 12 in case of diesel by way of amendment of the Eighth Schedule of the Finance Act.

Economists said the move would impact retail inflation by over half a percentage point at least. “With lower consumption, there was loss of revenue for Centre and states, who earn Rs 6 trillion annually or Rs 50,000 crore monthly from fuel. Amid lockdown in April, the collection must have come down to just Rs 5,000 crore, and this will hold for May.

This means that Centre and states have lost 20 per cent of annual revenue from fuel. Hence, they have hiked duties to recover losses,” said Madan Sabnavis, chief economist, CARE Ratings. He added that the hike will impact inflation by at least 0.6-0.7 percentage points.

According to industry experts, an estimate of the additional government revenue cannot be made as the consumption of petrol and diesel has dropped to 40 per cent of what it was before the lockdown. The duty hike comes following a drop in international crude oil prices in April, owing to lower consumption figures globally. At 11.50 pm on Tuesday, Brent was priced at $30.67 a barrel, while West Texas Intermediate (WTI) crude was seen at $24.36 a barrel. On Monday, the Indian basket of crude oil was priced at $23.38 a barrel, after touching a 15-year low last month.

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.
