Environmental Pollution — Prelims Strategy
Prelims Strategy
For Prelims, the strategy for Environmental Pollution (ENV-02) must be highly factual and detail-oriented. Focus on memorizing key data, names, and years. Firstly, master the constitutional provisions: Article 48A and 51A(g) are absolute must-knows.
Secondly, thoroughly learn the major environmental laws: Water Act 1974, Air Act 1981, and Environment Protection Act 1986. Understand their primary objectives, the year of enactment, and the key institutions they established (CPCB, SPCBs).
Pay close attention to the specific types of pollution and their characteristic pollutants (e.g., PM2.5, SOx, NOx for air pollution; heavy metals, nitrates for water/soil). Identify the major sources for each pollution type (e.
g., vehicular, industrial, agricultural). Crucially, keep track of recent government initiatives and policies like the National Clean Air Programme (NCAP) – its targets, base year, and key features – and BS-VI emission norms.
Landmark Supreme Court judgments (e.g., M.C. Mehta cases, Vellore Citizens Welfare Forum) are frequently tested; remember the case names, years, and the principles they established (e.g., absolute liability, polluter pays, precautionary principle).
Finally, practice numerous MCQs to identify common traps, such as confusing the year of an act or the specific body it established. Create flashcards for quick recall of facts, figures, and legal provisions.
