Rainwater Harvesting — Prelims Strategy
Prelims Strategy
For Prelims, your strategy for Rainwater Harvesting (RWH) should be highly factual and concept-driven. Prioritize understanding the 'what', 'where', and 'who'. Focus on the names and characteristics of traditional RWH methods (e.
g., Kunds, Johads, Baolis, Ahar-Pyne) and their geographical locations. Memorize the key components of modern RWH systems (catchment, first-flush, filter, storage/recharge structures) and their functions.
Be thorough with the major government schemes (Jal Shakti Abhiyan, MGNREGA, Atal Bhujal Yojana) and their specific RWH-related components. Remember the constitutional provisions (Entry 17 State List, 73rd/74th Amendments) and the National Water Policy (2012) directives.
Pay attention to states that have made RWH mandatory. Questions often test your ability to differentiate between similar terms (e.g., percolation tank vs. recharge pit) or identify the correct benefits (environmental vs.
economic). Practice MCQs that involve matching traditional systems with regions or identifying the correct statements about policy initiatives. Vyyuha advises creating flashcards for key terms, schemes, and examples to ensure quick recall under exam pressure.
Don't just read; actively test yourself on these specifics.
