UPSC Editorial Analysis: Tackling Poor Air Quality in India

*General Studies-3; Topic: Conservation, environmental pollution and degradation, environmental impact assessment.*

Introduction

• Air pollution is one of the most significant environmental risks in India, with levels of particulate matter (PM10 and PM2.5) exceeding World Health Organization (WHO) guidelines in most cities.

• Its persistence year-round, exacerbated by winter conditions, poses challenges for public health, economic productivity, and environmental sustainability.

• Addressing air pollution requires systemic reforms and multifaceted interventions across sectors.

Key Sources of Air Pollution in India

• Transport Sector

• Dominance of Fossil Fuels: Increasing vehicle numbers and poor vehicular standards contribute significantly to PM2.5 emissions.

• Traffic Congestion: High congestion levels exacerbate emissions, even in cities with metro systems due to inadequate last-mile connectivity.

• Policy Challenges: Although Delhi-NCR enforces a 10-year age limit on commercial vehicles, implementation is inconsistent. The slow transition to electric vehicles (EVs) reflects a lack of infrastructure and incentives.

• The slow transition to electric vehicles (EVs) reflects a lack of infrastructure and incentives.

• Public Transport Deficiency: Suboptimal performance of public transportation systems increases dependency on private vehicles.

• Industrial Sector

• Usage of Polluting Fuels: Biomass, coal, and unauthorized fuels dominate medium and small-scale enterprises. Poor operational practices and lack of emissions monitoring undermine installed air pollution control devices.

• Poor operational practices and lack of emissions monitoring undermine installed air pollution control devices.

• Municipal Waste Management

• Open Burning of Waste: Inefficiency in waste segregation leads to increased landfill fires and burning of municipal solid waste. Lack of infrastructure for waste treatment remains a major challenge.

• Lack of infrastructure for waste treatment remains a major challenge.

• Re-Suspended Dust

• Urban Infrastructure Gaps: Dust from unpaved roads, construction sites, and barren lands contributes heavily to PM10 levels.

• Agriculture

• Stubble Burning: Parali burning in northern states like Punjab and Haryana exacerbates winter air pollution in Delhi-NCR.

• Unsustainable Practices: Excessive fertilizer use leads to ammonia emissions, further degrading air quality.

• Rural Emissions

• Biomass Burning: Rural households use biomass for cooking and heating, leading to high emissions of particulate matter.

• Regional Contribution: Emissions from rural areas impact urban air quality due to interconnected airsheds.

Impacts of Air Pollution

• Public Health

• Increases the prevalence of respiratory diseases, cardiovascular issues, and lung cancer. Worsens health inequities, as marginalized populations are most affected.

• Environmental Degradation

• Affects biodiversity and soil quality, especially in regions reliant on agriculture.

Lessons from China

• Beijing’s Phased Approach

• 1970–1990: Focused on controlling emissions from coal-fired plants. 1990–2000: Addressed industrial and vehicular emissions. 2000 Onwards: Adopted a regional pollution strategy targeting complex sources.

Policy Recommendations

• Regional Airshed Management: Adopt a regional approach to manage emissions, as pollution often transcends city boundaries.

• Integration with Climate Policy: Align air quality goals with carbon emission reduction strategies to maximize impact.

• Public Health Budget Allocation: Redirect a portion of the health budget toward air pollution mitigation measures.
