Marine Pollution — Prelims Strategy
Prelims Strategy
For Prelims, a strong foundational understanding of marine pollution is non-negotiable. Begin by mastering the definitions of key terms like eutrophication, bioaccumulation, biomagnification, and different types of plastics (macro, micro, nanoplastics).
Pay close attention to the major sources of pollution, distinguishing between land-based and sea-based contributions, and specific examples for each. Memorize the core international conventions: MARPOL (Annexes are important), UNCLOS (Part XII), London Protocol, Basel, and Stockholm Conventions – know their primary focus.
Similarly, for India, be thorough with the Environment (Protection) Act, Water Act, and especially the Coastal Regulation Zone (CRZ) Notification, 2019, including its categories and restrictions. Government initiatives like Swachh Sagar Abhiyan, Blue Flag certification, and the Single-Use Plastic ban are high-priority.
Focus on the nodal agencies responsible for marine pollution control in India (e.g., Indian Coast Guard for oil spills). Practice MCQs that test direct facts, cause-effect relationships, and the correct pairing of conventions with their objectives.
Vyyuha's advice: create flashcards for conventions and their provisions, and regularly update your knowledge with current affairs related to marine pollution, noting specific dates and research findings.
