A CLEAN AIR ASIA INDIA INITIATIVE
A study from the Indian Institute of Technology, Delhi, on another possible developmental impact of air pollution it is said to be the first study to estimate the association of early-life exposure to ambient PM2.5 on child height-for-age at the range of ambient pollution exposures observed in India.
Air pollution imposes enormous public health and economic burdens in northwest India. Groundwater conservation policies appear to be exacerbating the crisis by concentrating agricultural burning in the late fall with a 39% higher peak fire intensity occurring when meteorological conditions favour poor air quality. Reconciling food security, resource depletion and environmental quality tradeoffs is necessary for achieving sustainable development in the breadbasket region of India.
More than 660 million Indians live in areas that exceed the Indian National Ambient Air QualityStandard (NAAQS) for fine particulate (PM2.5) pollution. Our research suggests that if India wereto meet its own standards, life expectancy would increase by more than one year on average.Moreover, if India were to meet the WHO’s air quality standard, its people would live aboutfour years longer on average.
Scalable exposure assessment approaches that capture personal exposure to particles for purposes of epidemiology are currently limited, but valuable, particularly in low-/middle-income countries where sources of personal exposure are often distinct from those of ambient concentrations.
A new study from the University of Arizona and the Georgia Institute of Technology finds that air pollution from coal-fired power plants and other sources is weakening the monsoon, placing in peril food security in India, China, Pakistan, Thailand and other countries.
The rapid economic growth and steep population increase in India’s urban areas, and the lack of policy measures to control pollution in these regions, are causing public health problems, significant environmental degradation, including of air, water, and land, and increased production of greenhouse gases. Together, these undermine the potential for sustainable socio-economic development of the country, and will particularly have severeimplications for the poor.
Since the pre-industrial era, anthropogenic activities have resulted in a significant increase in anthropogenic aerosol burden, which in turn has affected Earth’s radiative balance.
Air quality in megacity Delhi affected by countryside biomass burning
Air pollution due to crop stubble burning in northern India is a leading risk factor of acute respiratory infections and causes an estimated economic loss of $30 billion annually, according to a study unveiled Monday.
This is an updated factsheet from the Natural Resources Defense Council and partners at the Public Health Foundation of India and Indian Institute of Public Health-Gandhinagar. It aims to “highlight city efforts and share knowledge among cities
It ranks “extreme weather events” and “failure of climate change mitigation and adaptation” as the top two risks, based on a survey of 1,000 leaders in the public sector, private sector, academia and civil society.
Studies have estimated sector-specific premature mortality from ambient PM2.5 exposure in India and shown residential energy use is the dominant contributing sector. In this study, we estimate the contribution of PM2.5 and premature mortality from six regions of India in 2012 using the global chemical transport model.
Premature mortality from current ambient fine particulate (PM2.5) exposure in India is large,but the trend under climate change is unclear. Here we estimate ambient PM2.5 exposure upto 2100 by applying the relative changes in PM2.5 from the baseline period (2001–2005) derivedfrom Coupled Model Inter-comparison Project 5 (CMIP5) models to the satellite-derivedbaseline PM2.5.
Air pollution is a major planetary health risk, with India estimated to have some of the worst levels globally.To inform action at subnational levels in India, we estimated the exposure to air pollution and its impact on deaths, disease burden, and life expectancy in every state of India in 2017.
The report finds that the value of health gains from climate action would be approximately double the cost of mitigation policies at the global level, and the benefit-to-cost ratio is even higher in countries such as China and India.
Gati Foundation, a Dehra Dun, Uttarakhand based, is a research and policy think-tank has come up with a new report on impacts of air pollution on health.
The researchers wanted to know how replacing coal-fired powerplants in China and India with clean, renewable energy could benefit human health and save lives in the future. They found that eliminating harmful emissions from powerplants could save an estimated annual 15 million years of life in China and 11 million years of life in India.

A recent report from the Centre for Science and Environment in Delhi that provides an analysis and ranking of 14 cities in India.
A report written by researchers from the University of Colorado and the University of Kansas.
This report from Harvard University and the University of Chicago presents their recommendations towards cleaning India’s air. The recommendations include: Improving emissions monitoring by better aligning incentives of auditors, providing regulators with real-time data on polluters’ emissions, applying monetary charges for excess emissions, providing the public with information about polluters, and using markets to reduce abatement costs and pollution.
A recent report from The Energy and Resource Institute in Delhi identifies major sources of pollution in Delhi NCR.
Researchers compared India’s existing and planned policies to a more aggressive plan to reduce emissions. They used a high-resolution computer model to estimate the pollution levels people breathe at ground level throughout India and test how different emissions policies would affect their exposure and health.
The air pollution status in Delhi has undergone many changes in terms of the levels of pollutants and the control measures taken to reduce them in the past 10 years. This report provides an evident perception of Delhi’s Air pollution status and its health effect and the control measures adopted in the city. The report was published in 2013 in Indian Journal of Community Medicine.
This study by National Environmental Engineering Research Institute includes components like assessment of present air quality status at seven different sites in Mumbai, quantification of percentage share of air pollutant emissions attributable to transport, industrial, commercial, residential and other activities. It also included projected growth trend in emissions for the next 5 and 10 years from various source categories. Different impact scenarios were generated for the development of an appropriate action plans and finally to delineate the impact of implementation of sector wise short and medium term interventions for air quality improvement.
The study focuses on assessing the status of respiratory morbidity in Delhi over a four years period from 2000-2003. An attempt was made to investigate the role of important pollutants (SO(2), NO(2), SPM and RSPM) and various meteorological factors (temperature minimum & maximum, relative humidity at 0830 and 1730 hrs. and wind speed) in being responsible for respiratory admissions on account of COPD, asthma and emphysema.
Development and urbanization over the past decade have led to rapid increase in the population of Delhi, the metropolitan city of India. Consequently, there has been a tremendous increase in the number of vehicles, which are causing very high levels of air pollution. The study shows the trend of air pollutants in delhi over a decade from 2000 to 2010.
The study was done in Shahdara industrial area of Delhi in 2000 and examined the effects of indoor and outdoor air pollutant levels on the respiratory health of 394 children aged 7 to 15 years.
The study done in Indore city shows the effect on the effect of air pollution on plant morphology. The leaves of a more polluted site recorded a reduction in chlorophyll content in the leaves of Bougainvillea spectabilis and Delbergiasisoo plant due to probable emissions of SO2, NO2, and other gases in the air. The parameter, pH of leaf wash, and electrical conductivity of leaf wash showed that air pollutant content like SO2 , NO2 and suspended particle matter affect the physiology of plants.
