Who has to bear the Global Burden Of Disease ?
This year the annual festival of Diwali in India is influencing the country’s social and geological climate long after it’s actual date of 19th October 2017. After the Supreme Court of India had banned the sale of Diwali Crackers[1] [2] in the National Capital Region of Delhi, the topic was the subject of a lot of debate in India coupled with curiosity regarding the impact of the ban on the ambient air quality.
Shortly after Diwali, the media started reporting some reduction in levels as compared to 2016, but cautioned that the levels were still high. The fact that the high pollutions levels were also attributable to the still weather, was not adequately highlighted [3]. In fact when the region started experiencing favorable weather conditions, the air quality improved. At the same time the Center for Science and Environment[4] argued that the situation could have been worse without the Diwali crackers ban.
“There was a definite decline in burning of firecrackers because of the ban. But the high moisture content and calm winds on Friday (the day after Diwali) trapped pollutants, making some parts of Delhi more polluted than others,” – Central Pollution Control Board member-secretary A Sudhakar.
As if to reprimand the people in Delhi (NCR) of their obstinate behavior, news of a “study published in the Lancet Journal” was reported by most media houses [5][6]. By clubbing it in context of the rise in pollution levels after Diwali, it was indirectly implied that bursting Diwali Crackers may cause the death of millions of people in India.
This prompted me to actually read the Lancet Report so as to understand what the study was really all about.
The report of the Lancet Commission on pollution and health comments on data in 2015. It is a two-year project .More than 40 international health and environmental authors led by environmental scientist Philip Landrigan [7] were involved. Prominent authors from India include:
- Member of Parliament, Economist and politician (Indian National Congress), former Minister of State for Environment, Mr. Jairam Ramesh [8]
- Prof. Mukesh Khare [9], IIT Delhi, Chairman of State Environment Impact Assessment Authority.
Interestingly, Prof.Khare was also part of the following study [10] regarding the influence of odd–even car trial on fine and coarse particles in Delhi, which concluded:
“Any further trial will need to be planned very carefully if an effect due to traffic alone is to be differentiated from the larger effect caused by changes in meteorology and especially wind direction.”
