Delhi Smog: Odd-Even Car Rule May Return; Consider Cloud Seeding to curb Pollution : HC

The court said that though stubble-burning was the "visible villain", authorities should address the "other elephants in the room" such as dust generated by road and construction activity as well as vehicular and industrial pollution.

New Delhi, November 9, 2017 : The Delhi High Court on Thursday said there was an “emergency situation” vis-a-vis pollution in Delhi-NCR region and asked the Delhi government to consider vehicular odd-even scheme and cloud seeding to induce artificial rain.

The court also asked the Centre to hold meetings with Delhi and National Capital Region authorities to bring in short-term measures to control pollution immediately and to submit a report to it on November 16, the next date of hearing.

Issuing a slew of direction as immediate measures to control pollution in Delhi-NCR, the court banned felling of trees, ordered sprinkling of water on roads to control dust and strict enforcement of construction code to ensure that the air was not polluted.

A Division Bench of Justice S. Ravindra Bhat and Justice Sanjeev Sachdeva also directed the Chief Secretary in the Ministry of Environment and Forest and Climate Control to call an emergency meeting with his counterparts in Delhi, Haryana, Punjab, Rajasthan and Uttar Pradesh and pollution control agencies within three days to discuss ways to curb pollution.

The bench said the Chief Secretaries will also consider the feasibility of cloud seeding to bring down air pollution. This, the bench said, was not a very expensive process and Bengaluru had adopted it.

The court asked the Delhi government to consider bringing back the odd-even scheme — under which vehicles of odd and even registration numbers, with exceptions, ply on roads on designated days — to control traffic congestion and unclog the capital.

But the court questioned the government move to increase parking rates by four times.

“If somebody has to go to a hospital or buy important items, he ends up paying four times more for the parking,” the bench said.

The court said that though stubble-burning was the “visible villain”, authorities should address the “other elephants in the room” such as dust generated by road and construction activity as well as vehicular and industrial pollution.

“London has faced this kind of air pollution. They term it as pea soup fog, which is a killer fog. This is a deadly mixture of construction and vehicular dust and other factors,” the bench said.

The court also directed the Delhi government to conduct a survey of all hospitals in the national capital on availability of oxygen to deal with emergency situations with regard to vulnerability of children and senior citizens.

It told the Delhi government to strictly regulate the entry of trucks into the city.

The court was hearing a suo motu case it initiated in 2015 to control air pollution in the national capital. (IANS)

Reduction in Air Pollution May Increase Life-Expectancy: Study

Findings of a Research indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution

Reductions in Air Pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, a new study suggests.

The study, published in the journal Annals of the American Thoracic Society, reviewed interventions that have reduced air pollution at its source. It looked for outcomes and time to achieve those outcomes in several settings, finding that the improvements in health were striking.

Starting at week one of a ban on smoking in Ireland, for example, there was a 13 per cent drop in all-cause mortality, a 26 per cent reduction in ischemic heart disease, a 32 per cent reduction in stroke, and a 38 per cent reduction in chronic obstructive pulmonary disease (COPD). Interestingly, the greatest benefits in that case occurred among non-smokers.

“We knew there were benefits from pollution control, but the magnitude and relatively short time duration to accomplish them were impressive,” said lead author Dean Schraufnagel from the American Thoracic Society in the US.

“Our findings indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution. It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately,” Schraufnagel added.

According to the researchers, In the US a 13-month closure of a steel mill in Utah resulted in reducing hospitalisations for pneumonia, pleurisy, bronchitis and asthma by half.

School absenteeism decreased by 40 per cent, and daily mortality fell by 16 per cent for every 100 µg/m3 PM10 (a pollutant) decrease.

Women who were pregnant during the mill closing were less likely to have premature births.

A 17-day ‘transportation strategy,’ in Atlanta, Georgia during the 1996 Olympic Games involved closing parts of the city to help athletes make it to their events on time, but also greatly decreased air pollution.

In the following four weeks, children’s visits for asthma to clinics dropped by more than 40 per cent and trips to emergency departments by 11 per cent. Hospitalizations for asthma decreased by 19 per cent.

Similarly, when China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.

“Fortunately, reducing air pollution can result in prompt and substantial health gains. Sweeping policies affecting a whole country can reduce all-cause mortality within weeks,” Schraufnagel said.
