Previous govts hated development, says PM Modi

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.

Thiruvananthapuram, Mar 30: Kerala reported 32

Kannur reported 15 cases, while Wayanad and Idukki reported two each, Chief Minister Pinarayi Vijayan told reporters here after a COVID-19 review meeting.

Of the 32 cases, 17 had come from abroad and 15 had been infected through contact.

A total of 213 people are presently under treatment in Kerala.

At least 1.50 lakh people are under surveillance in the state and 623 are in isolation wards of various hospitals.

New Delhi, Mar 2: As communal violence spiked in north-east Delhi earlier this week, Hindu, Muslim and Sikh residents of a colony came together and stood guard against frenzied mobs which ran riot in nearby areas vandalising homes, shops and torching cars.

They have not let their guard down even as the situation is limping back to normalcy following four days of violence that has claimed at least 42 lives and left over 200 injured.

The B-Block colony in Yamuna Vihar has a Hindu-dominated Bahjanpura on one side and Muslim populated Ghonda on the other.

People from all faiths in the locality sit outside their homes at night and deal with any suspected outsider, Arib, a dentist in his 30s, said.

"It is the sloganeering by mobs that causes panic in the dead of night. Such slogans are from both sides and we hear groups of people moving forward towards our area.

"This is where we let the Muslim locals deal with Muslim groups and Hindu residents deal with Hindu groups coming from outside," he said.

Businessmen, doctors and people working at government offices stuck together as violence reached its crest on Monday and Tuesday, and have been guarding the locality round the clock.

Earlier, the locals had claimed inadequate police deployment in the area, but were satisfied as patrolling by security personnel increased in the last two days.

Charanjeet Singh, a Sikh who owns a transport firm, said residents have ensured that not too many people gather to guard the colony at night. It has been decided not use sticks or rods, an idea which seems to have worked in maintaining peace, he said.

"I was 10 years old when we came to this locality from Uttar Pradesh's Meerut in 1982. There were riots in 1984 and tension in 2002, but even then our area remained peaceful. We have always been united and that is the way we have helped each other," Singh, who is now in his 50s, told PTI.

Faisal, a businessman in his 30s, said after two days of major violence, there was palpable tension in the area. "Nobody could sleep in the neighbourhood even on Wednesday and Thursday when the situation was brought under control," he said.

Faisal said around 4 am on Wednesday, three to four miscreants had torched a car, but were chased away by vigilant residents. They raised an alarm and others gathered, saving other vehicles parked nearby from being damaged, he added.

On the idea of not keeping sticks while guarding B-Block, Singh said, "Violence begets violence, crowd begets crowd. We thought if somebody would see sticks or rods in our hands from a distance and large crowds standing guard, it is likely they would want to come prepared. This could fuel violence."

"Now, if there is some young man returning late in the night, we identify if he belongs to our area. If not, we normally inform him about the situation and guide him to his destination, if required," he added.

Seventy-year-old V K Sharma said people in his colony never had any trouble with each other, as he blamed "outside elements" for the violence in north-east Delhi.

"Some people have some problem with symbols. If they find a particular religion's symbol on a shop, home or a car, they vandalise it.

"This is on both sides, Hindus as well as Muslims. But not all people in all religion are like that. There are good people who outnumber these handful people involved in violence," he said.

The violence happened for two days but it would take months for fear to subside, Sharma said, as he took out his two granddaughters, aged nine and two, out for ice cream.

"I cannot reduce the tension outside my home, but at least I can make these kids feel good by reducing their craving for ice cream,” he added.

Colony resident Shiv Kumar, a property consultant, and Wasim, a government official, said they too were members of this voluntary guards' team of the colony which stays up at night to fend off miscreants.
