Air Pollution / Air Quality Management

Air Pollution / Air Quality Management क्या है?

The presence of harmful substances in the atmosphere, including gases, particulate matter, and biological molecules, that cause discomfort, disease, or death to humans, damage other living organisms, or harm the natural environment. Air Quality Management refers to the strategies and policies implemented to monitor, control, and reduce air pollution.

ऐतिहासिक पृष्ठभूमि

Industrialization and rapid urbanization post-independence, particularly since the 1980s, have led to a significant increase in air pollution in India. Major cities like Delhi have consistently ranked among the most polluted globally, leading to public health crises and increased policy focus in recent decades. The Bhopal Gas Tragedy (1984) further highlighted the need for comprehensive environmental protection.

Evolution of Air Quality Management in India

This timeline traces key legislative, policy, and judicial interventions in India's journey towards air quality management, highlighting major milestones and recent developments up to 2026.

Air Quality Management: A Holistic View

This mind map illustrates the interconnected components of air quality management, from sources and impacts to legal frameworks and government initiatives, emphasizing a holistic approach for UPSC preparation.
