India tops world in pollution deaths in 2015

The overall findings of the Lancet Commission on Pollution and Health (2017) were covered in a previous blog post. This post is about the references to India in the Report. The figures are based on data obtained from more than 75 Indian sites.

Main points on pollution and health in India and the other developing countries:
·      While almost all (92%) pollution-related deaths occurred in low- and middle-income countries, the greatest impacts are seen in countries that are undergoing rapid development and industrialisation — with pollution responsible for up to one in four deaths in the most severely affected countries like India, Pakistan, China, Bangladesh, Madagascar and Kenya.
·      India and Bangladesh recorded the largest increases in pollution-related deaths among the 10 most populous countries for the year.

·      In 2015, the maximum number of deaths due to pollution occurred in India (25 lakh) followed by China (18 lakh). Thus, nearly a quarter of global fatalities due to pollution were in India.

·      Air pollution alone killed more than 18 lakh lives in India. Most of these deaths were caused by heart disease, stroke, lung cancer and chronic obstructive pulmonary disease, triggered by pollution.
·      More than 50% of global deaths due to ambient air pollution in 2015 occurred in India and China.
·      Particulate matter pollution in the air was severe in several cities in India and China: Average annual concentrations of PM 2.5 (particulates less than 2.5 microns in width) were greater than 100 microgrammes per cubic metre.
·      Water pollution killed nearly 6.46 lakh Indians, while other forms of pollution, including passive smoking and exposure to lead, resulted in the death of another 1.68 lakh people.

The Lancet Commission Report on Global Pollution and Health

The Lancet Commission on Pollution and Health published its Report on October 19, 2017. The Commission is an initiative of The Lancet (one of the world’s most prestigious and widely read medical journals), the Global Alliance on Health and Pollution (GAHP), and the Icahn School of Medicine at Mount Sinai, with additional coordination and input from UNEP, UNIDO and the World Bank.

The aim of the Lancet Commission is to raise global awareness of pollution, end neglect of pollution-related disease, and mobilise the resources and the political will needed to effectively confront pollution. The aim of the Commission is also to reduce air, soil and water pollution by communicating the extraordinary health and economic costs of pollution globally, providing actionable solutions to policy-makers and dispelling the myth of pollution’s inevitability.

The Commission comprises many of the world’s most influential leaders, researchers and practitioners in the fields of pollution management, environmental health and sustainable development.

Main conclusions of the Report
·      Pollution is the largest environmental cause of disease and premature death in the world today. Diseases caused by pollution were responsible for an estimated 9 million premature deaths in 2015—16% of all deaths worldwide— three times more deaths than from AIDS, tuberculosis, and malaria combined and 15 times more than from all wars and other forms of violence. In the most severely affected countries, pollution-related disease is responsible for more than one death in four.
·      Pollution disproportionately kills the poor and the vulnerable. Nearly 92% of pollution-related deaths occur in low-income and middle-income countries and, in countries at every income level, disease caused by pollution is most prevalent among minorities and the marginalised.
·      Despite its substantial effects on human health, the economy, and the environment, pollution has been neglected, especially in low-income and middle-income countries, and the health effects of pollution are under- estimated in calculations of the global burden of disease.
·      Pollution is costly. Pollution-related diseases cause productivity losses that reduce gross domestic product (GDP) in low-income to middle-income countries by up to 2% per year.
·      Pollution endangers planetary health, destroys eco-systems, and is intimately linked to global climate change. Fuel combustion—fossil fuel combustion in high-income and middle-income countries and burning of biomass in low-income countries—accounts for 85% of airborne particulate pollution and for almost all pollution by oxides of sulphur and nitrogen. Fuel combustion is also a major source of the greenhouse gases and short-lived climate pollutants that drive climate change. Key emitters of carbon dioxide, such as electricity-generating plants, chemical manufacturing facilities, mining operations, deforestation, and petroleum-powered vehicles, are also major sources of pollution. Coal is the world’s most polluting fossil fuel, and coal combustion is an important cause of both pollution and climate change.
·      In many parts of the world, pollution is getting worse. Ambient air pollution, chemical pollution, and soil pollution—the forms of pollution produced by industry, mining, electricity generation, mechanised agriculture, and petroleum-powered vehicles—are all on the rise.
·      Chemical pollution is a great and growing global problem. Chemicals and pesticides have repeatedly been responsible for episodes of disease, death, and environmental degradation.
·      Cities, especially rapidly growing cities in industrialising countries, are severely affected by pollution.

Recommendations of the Report
(1) Make pollution prevention a high priority nationally and internationally and integrate it into country and city planning processes.  
(2) Mobilise, increase, and focus the funding and the international technical support dedicated to pollution control.
(3) Establish systems to monitor pollution and its effects on health.
(4) Build multi-sectoral partnerships for pollution control.
(5) Integrate pollution mitigation into planning processes for non-communicable diseases.
(6) Research pollution and pollution control: Research is needed to understand and control pollution and to drive change in pollution policy.
