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, Feb 18: India emerged as the world's fifth-largest economy by overtaking the UK and France in 2019, says a report.

A US-based think tank World Population Review in its report said that India is developing into an open-market economy from its previous autarkic policies.

"India's economy is the fifth-largest in the world with a GDP of $2.94 trillion, overtaking the UK and France in 2019 to take the fifth spot," it said.

The size of the UK economy is $2.83 trillion and that of France is $2.71 trillion.

The report further said that in purchasing power parity (PPP) terms, India's GDP (PPP) is $10.51 trillion, exceeding that of Japan and Germany. Due to India's high population, India's GDP per capita is $2,170 (for comparison, the US is $62,794).

India's real GDP growth, however, it said is expected to weaken for the third straight year from 7.5 per cent to 5 per cent.

The report observed that India's economic liberalisation began in the early 1990s and included industrial deregulation, reduced control on foreign trade and investment, and privatisation of state-owned enterprises.

"These measures have helped India accelerate economic growth," it said.

India's service sector is the fast-growing sector in the world accounting for 60 per cent of the economy and 28 per of employment, the report said, adding that manufacturing and agriculture are two other significant sectors of the economy.

May 27: At a time when India is struggling with the deadly coronavirus, huge swarms of locusts in many states has bought nightmares to the farmers.

Experts warn of extensive crop losses if authorities fail to curb the fast-spreading swarms by June when monsoon rains spur rice, cane, corn, cotton, and soybean sowing.

Locusts entered India after traveling from Africa through Yemen, Iran and Pakistan.

After massive devastation in Pakistan, t swarms of locusts entered India through Rajasthan and Gujarat. The number is so large that the farmers and authorities are feeling helpless in tackling the threat.

The situation has become more alarming as the locusts is spreading across the country at an extremely fast rate. After badly affecting the crops in Rajasthan, Gujarat, Maharashtra, and Madhya Pradesh, the swarm of locust have now entered Uttar Pradesh.

In Rajasthan alone, the locust attack has damaged 5 lakh hectares of crop and nearly 17 districts of Madhya Pradesh have also seen their terror. Earlier from May 2019 to February 2020, too, the locust swarms entered India several times.

Speaking on the current situation, Dr Ram Pravesh, District Agricultural Officer, Agra, Uttar Pradesh said the Department of Agriculture is working with farmers in dealing with the situation. He urged the farmers to inform their Mandal Krishi Adhikari if they require any help.

India's largest-ever locust attack was in 1993 when more than three lakh hectares of cultivated land were completely destroyed.

Earlier in 2020, farmers salvaged their wheat and oilseed crops from a previous locust scourge.
