Impact on Biodiversity — Prelims Strategy
Prelims Strategy
For Prelims, mastering 'Impact on Biodiversity' requires a strong foundation in core concepts and factual details. Begin by clearly defining key scientific terms like 'phenological mismatch,' 'trophic cascades,' 'extinction debt,' 'thermal tolerance,' 'ocean acidification,' and 'range shifts.
' Understand the specific mechanisms through which climate change affects biodiversity (temperature, precipitation, extreme events, sea-level rise). Focus on vulnerable Indian ecosystems – Western Ghats, Eastern Himalayas, Sundarbans, and coral reefs of Andaman & Lakshadweep – memorizing their specific threats and unique biodiversity.
Pay close attention to international conventions (CBD, CITES, Ramsar, Paris Agreement Article 6.8) and their relevance to biodiversity and climate. Familiarize yourself with India's legal frameworks (Wildlife Protection Act 1972, Biological Diversity Act 2002, Forest Rights Act 2006) and their key provisions.
Practice MCQs that test conceptual understanding, specific examples, and the interlinkages between climate change and biodiversity. Create flashcards for facts, figures, and definitions. Regularly revise the latest reports from IPCC and outcomes from global conferences (e.
g., CBD COP15, recent COPs) to stay updated on current affairs hooks. Remember, Prelims often tests your ability to distinguish between similar-sounding concepts and identify correct examples.
