Q.How does biodiversity vary in India? How is the Biological Diversity Act, 2002 helpful in conservation of flora and fauna?

Body

Variation in Biodiversity across India

• Diverse Ecosystems: India spans diverse habitats from deserts and grasslands to marine zones. For example, the Western Ghats host tropical evergreen forests with endemic species like the Nilgiri Tahr.
• Climatic Zones: Variations range from tropical rainforests in the Andaman & Nicobar Islands to alpine vegetation in the Himalayas, which support species like the snow leopard.
• Species Richness: Unique habitats like the Sundarbans mangroves host the Bengal tiger and diverse estuarine species.
• Endemism: Isolated regions like the Andaman and Nicobar Islands exhibit high endemism, such as the Andaman wild pig.
• Biodiversity Hotspots: India contains four global biodiversity hotspots: the Himalayas, Western Ghats, Indo-Burma, and Sundaland.
• Agrobiodiversity: India possesses a rich repository of indigenous crop varieties (e.g., thousands of native rice varieties) adapted to local microclimates.

• Regulation of Biological Resources: It controls access to biological resources, requiring commercial and research entities to obtain prior approval, preventing unauthorized exploitation.
• Decentralized Conservation (BMCs): It mandates the creation of Biodiversity Management Committees (BMCs) at local body levels to document resources via People’s Biodiversity Registers (PBRs).
• Sustainable Use: It provides guidelines to ensure biological resources are harvested sustainably without causing species depletion.
• Protection of Traditional Knowledge: It prevents biopiracy by protecting the intellectual property rights of indigenous communities regarding local flora and fauna.
• Access and Benefit Sharing (ABS): It ensures that commercial profits derived from local biological resources are shared equitably with local custodians.
• Institutional Framework: It established a three-tier regulatory structure: the National Biodiversity Authority (NBA), State Biodiversity Boards (SBBs), and local BMCs.
