Is air pollution a South Asian crisis?, Pg10

Key Highlights:

• In November 2024, eastern and northern Pakistan and northern India experienced a severe pollution event known as the '2024 India-Pakistan Smog'.
• Lahore and Delhi competed for the title of the most polluted city globally, with high AQI readings.
• Bangladesh and Nepal also face significant air pollution issues, with Dhaka and Kathmandu experiencing worsening AQI levels.
• A World Bank study estimates that high AQI levels in India result in about 3% of its GDP being spent on healthcare and lost labor capital.

Reducing Air Pollution in South Asia (2).png

Detailed Insights:

• The Indo-Gangetic Plain's topography contributes to a trans-national haze due to limited natural air ventilation and pollutant dispersal.
• Anthropogenic sources like industrial and vehicular emissions, and burning solid fuel, are major causes of poor air quality in South Asia.
• A UNEP report indicates that current consumption and production patterns drive climate change, exacerbating the air pollution crisis.
• Mitigation requires long-term strategies focusing on decarbonization, agricultural reforms, and reduced industrial emissions across borders.
• Poorly planned development, including increased vehicle sales and construction, contributes to deteriorating air quality in cities like Mumbai.
• A regional airshed scale management strategy is crucial for tackling air pollution effectively, as highlighted by an IIT Bhubaneshwar study.

Key Concepts Involved:

• AQI (Air Quality Index): A measure of air quality based on pollutants, indicating health risks.
• Anthropogenic Sources: Pollution sources caused by human activities, like industry and transportation.
• Decarbonization: Reducing carbon emissions through alternative energy and sustainable practices.
