SpiceJet cancels over 1,800 flights in domestic sector

New Delhi, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.

New Delhi, Jun 20: A rare celestial event, annular solar eclipse, which is popularly known as the "ring of fire" eclipse, will be visible this Sunday in India.

It will be the first solar eclipse of this year takes place on the summer solstice, which is the longest day in the Northern Hemisphere.

While people living along the path annular eclipse passing through Anupgarh, Suratgarh, Sirsa, Jakhal, Kurukshetra, Yamunanagar, Dehradun, Tapowan and Joshimath will be able to see the annular phase, people in rest of India can witness a partial eclipse, said the Ministry of Science and Technology.

When Moon comes between the Sun and Earth, the shadow falls on the surface of the Earth. The Sun is entirely covered by the Moon for a brief period. Those places that are engulfed by the dark, dense umbral shadow of the Moon experience the total solar eclipse. In the regions that plunge into the soft diffused penumbral shadow of the Moon experience the partial eclipse.

"Annular solar eclipse is a particular case of the total solar eclipse. Like the total solar eclipse, the Moon is aligned with the Sun. However, on that day, the apparent size of the Moon happens to be a wee smaller than the Sun. Hence the Moon covers the central part of the Sun, and the rim of the Sun appear like a 'ring of fire' in the sky for a very brief moment" explains Samir Dhurde of The Inter-University Centre for Astronomy and Astrophysics, Pune.

During the solar eclipse, the apparent size of the Moon is smaller than that of the Sun by 1 per cent, the expert said.

Allying rumours that the eclipse will mark the end of coronavirus, Aniket Sule, Chairperson, Public Outreach and Education Committee of the Astronomical Society of India, said: "Solar eclipse is caused when the Moon comes in front of the Sun for a short time. As seen from Earth eclipses occur somewhere in the Earth 2 to 5 times a year. Eclipses do not impact microorganisms on Earth. Likewise there no danger in eating of stepping out during an eclipse. No mysterious rays come out of the Sun during an eclipse."

Kochi, Apr 24: The central government on Thursday submitted a statement in the Kerala High Court on the three petitions challenging the contract between Kerala government and US-based data analytics company Sprinklr.

Assistant Solicitor General P Vijayakumar filed the statement on behalf of the central government, which is the second respondent in the case.

The statement said that the contract between the Kerala government and Sprinklr dilutes the rights of the people. It stated the contract does not specify the amount of compensation that individuals should receive in case of breach of privacy or misuse of information.

It also said that it was not clear whether the information was collected and handed over to the data analytics firm with full consent of the patients (suspected and otherwise).

''It is always preferable to utilise the services available in the government sector for sharing sensitive data required for analytical purposes.

The Government of India has introduced the 'Aarogya Setu' application for collection of health data and about seven crore Indian citizens have already downloaded the same. All the state governments are advised to promote the said application for fighting the pandemic," the statement said.

It was further submitted that the "Government of India with the support of NIC is capable of providing all the requirements relating to data storage, processing and application which are being offered the third respondent, if a request to that effect comes from the state government."

Kerala Congress leader Ramesh Chennithala and BJP state president K Surendran had earlier approached the Kerala High Court seeking cancellation of the state government's agreement with Sprinklr for processing of data related to COVID-19 patients.
