Biodiversity — Prelims Strategy
Prelims Strategy
For Prelims, biodiversity demands a meticulous, fact-oriented approach. Begin by mastering the core definitions: genetic, species, and ecosystem diversity, along with their measures (richness, evenness, Shannon, Simpson indices).
Pay close attention to India's status as a megadiverse country, its percentage of global species, and the specific characteristics of its four biodiversity hotspots (Western Ghats, Eastern Himalaya, Indo-Burma, Sundaland/Nicobar Islands) – including key endemic flora and fauna.
Memorize the years and key provisions of crucial Indian laws like the Wildlife Protection Act (WPA) 1972, Biological Diversity Act (BDA) 2002, and Forest Rights Act (FRA) 2006, along with the institutional bodies they establish (NBA, SBBs, BMCs).
Similarly, for international conventions (CBD, CITES, Ramsar, Nagoya, Cartagena), focus on their objectives, year of adoption, and India's role and commitments. Current affairs are paramount: track new protected area designations (National Parks, Wildlife Sanctuaries, Ramsar Sites), significant species discoveries or reintroductions (e.
g., Project Cheetah), and outcomes of major international conferences (e.g., Kunming-Montreal GBF, 30x30 target). Use mnemonics and flashcards for quick recall of lists and numbers. Practice numerous MCQs, paying attention to 'trap' options that often confuse similar concepts or misattribute objectives between conventions.
A strong foundation in these factual aspects will ensure high scores in this segment.
