How does biodiversity vary in India? How is the Biological Diversity Act, 2002 helpful in conservation of flora and fauna?
Approach · directive: “how”
What it asks · Describe how India's biodiversity varies by region and ecosystem, and explain how the 2002 Act, through its institutions and provisions, helps conserve flora and fauna.
The question has 2 parts — answer each
- How biodiversity varies across India: regions, ecosystems, hotspots and endemism
- How the Biological Diversity Act, 2002 helps conserve flora and fauna: aims, institutions, regulation and conservation tools, with their limits
Open with · India is a megadiverse country with about 7-8 per cent of the world's recorded species on about 2.4 per cent of its land area; richness varies with climate, terrain and altitude.
Cover
- Variation by region: Himalayan alpine and temperate forests, the wet evergreen forests of the Western Ghats, the rich north-east, dry Deccan and Thar zones, wetlands, mangroves, coral reefs and islands.
- Hotspots and endemism: four hotspots (the Himalaya, Indo-Burma, Western Ghats and Sundaland, which includes the Nicobar Islands), with high endemism in Western Ghats amphibians, reptiles and plants; crop and livestock diversity too.
- Aims of the Act: to conserve biological diversity, use its components sustainably, and share the benefits of biological resources and related knowledge fairly and equitably; it gives effect to the Convention on Biological Diversity.
- Three tiers: the National Biodiversity Authority, State Biodiversity Boards and local Biodiversity Management Committees, which record local knowledge in People's Biodiversity Registers.
- Regulation: NBA approval is needed for foreign nationals, non-resident Indians and foreign-owned firms to access biological resources; benefit-sharing with local communities; control over intellectual property claims based on Indian resources.
- Conservation tools: notification of Biodiversity Heritage Sites and threatened species; the Act works alongside the Wildlife (Protection) Act, 1972 and the Forest Rights Act, 2006 through community management.
- Limits: weak funding and capacity of local committees, slow registers, thin benefit-sharing so far, and complaints of compliance burden on research and traditional healers.
Close with · India's rich and varied biodiversity is protected best when the Act's local committees are empowered and benefit-sharing reaches the communities that conserve it.

Model answer · 276 words (UPSC limit 250) · Minimalist IAS
India is a megadiverse country holding about 7-8 per cent of the world's recorded species on about 2.4 per cent of its land; that richness is spread unevenly, following climate, terrain and altitude.
How biodiversity varies
- By region: alpine and temperate forests of the Himalaya, wet evergreen forests of the Western Ghats, the species-rich north-east, the dry Deccan and the Thar, and the wetlands, mangroves, coral reefs and islands of the coast.
- Hotspots: four of the world's biodiversity hotspots touch India, the Himalaya, Indo-Burma, the Western Ghats and Sundaland (the Nicobar Islands).
- Endemism: the Western Ghats hold amphibians, reptiles and plants found nowhere else; India's crop and livestock varieties add agricultural diversity.
How the Act helps conservation
- Aims: to conserve biological diversity, use its components sustainably and share the benefits of biological resources and related knowledge fairly, giving effect to the Convention on Biological Diversity.
- Three tiers: the National Biodiversity Authority, State Biodiversity Boards and local Biodiversity Management Committees, which document local species and knowledge in People's Biodiversity Registers.
- Regulating access: foreign nationals, non-resident Indians and foreign-owned firms need NBA approval to use Indian biological resources, and intellectual property claims built on them are checked; benefit-sharing returns value to local communities.
- Conservation tools: notification of Biodiversity Heritage Sites and threatened species, working alongside the Wildlife (Protection) Act, 1972 and community management under the Forest Rights Act, 2006.
Limits
- Local committees lack funds and capacity, registers are slow to complete, benefit-sharing has been thin so far, and researchers and traditional healers complain of compliance burden.
India's varied biodiversity is best protected when the Act's local committees are empowered and benefit-sharing reaches the communities that actually conserve it.
