Air Pollution — Prelims Strategy
Prelims Strategy
For Prelims, the Vyyuha approach emphasizes precise factual recall and conceptual clarity. Focus on the definitions of key pollutants (PM2.5, PM10, SOx, NOx, O3), their sources, and health impacts. Memorize the specific provisions and years of key acts like the Air (Prevention and Control of Pollution) Act, 1981, and the Environment (Protection) Act, 1986.
Understand the structure and functions of bodies like CPCB, SPCBs, and CAQM. Crucially, know the components and categories of the Air Quality Index (AQI) and the targets of the National Clean Air Programme (NCAP) (e.
g., 20-30% reduction by 2024 with 2017 as base year). Be familiar with major government initiatives like BS-VI norms, GRAP, and schemes promoting electric vehicles. Pay attention to constitutional articles (21, 48A, 51A(g)) and their interpretations.
Recent data points (e.g., WHO guidelines, India's pollution-related death figures, EV sales) and significant current affairs (Supreme Court rulings on stubble burning) are also high-yield areas. Practice MCQs that test your ability to differentiate between similar concepts and identify correct statements about policies and their objectives.
The trap options often involve incorrect years, percentages, or misattribution of provisions.
