Lesson 6. Environment & Ecology: Biodiversity to Climate Governance
Environment & Ecology has evolved from a niche topic to a major, non-negotiable segment, deeply integrated with current affairs. The syllabus revolves around core ecological concepts (ecosystems, food chains, keystone species), biodiversity (types, significance, threats), and conservation efforts (in-situ like Protected Areas, ex-situ like zoos). A thorough knowledge of international conventions and protocols (UNFCCC, CBD, CITES, Ramsar, Montreal Protocol) and India’s specific commitments and initiatives (National Action Plan on Climate Change, its missions, Green India Mission) is essential. Topics frequently tested include protected area network (National Parks, Wildlife Sanctuaries, Tiger Reserves—their location and species), endangered species (Great Indian Bustard, Snow Leopard), and environmental issues (air pollution, waste management, wetland conservation). Recent developments like the Kunming-Montreal Global Biodiversity Framework, COP28 outcomes, or India’s Green Hydrogen Mission are typical current-affairs-cum-environment questions. Understanding the intersection of environment with tribal rights (Forest Rights Act) and infrastructure projects is also key. Additional Resources: Shankar IAS Academy’s ‘Environment’ book is a comprehensive primer. The official websites of the MoEFCC, UNFCCC, and Convention on Biological Diversity are primary sources for policy documents. The ‘Down To Earth’ magazine provides excellent analytical coverage of environmental issues. The ENVIS centres’ portals offer state-specific ecological data.
