Biological Diversity Act, 2002

The Biological Diversity Act, 2002 (Act No. 18 of 2003) was enacted by the Indian Parliament to give domestic legal effect to the Convention on Biological Diversity (CBD), signed at the Rio Earth Summit in 1992 and ratified by India in 1994. The Act rests on the three core objectives of the CBD as stated in Article 1 of that Convention: conservation of biological diversity, sustainable use of its components, and fair and equitable sharing of benefits arising from the utilisation of genetic resources (the "ABS" principle). It came into force in 2003, with the Biological Diversity Rules, 2004 operationalising its provisions. The Act was further supplemented by the Nagoya Protocol on Access and Benefit-Sharing (2010), which India ratified in 2014, reinforcing the benefit-sharing architecture domestically through the Guidelines on Access to Biological Resources and Associated Knowledge and Benefits Sharing, 2014.

The Act establishes a three-tier institutional structure. At the apex stands the National Biodiversity Authority (NBA), a statutory body headquartered in Chennai, established under Section 8 and operational since October 2003. State Biodiversity Boards (SBBs) are constituted under Section 22 at the state level, while Biodiversity Management Committees (BMCs) are created under Section 41 at the local level by every local body (panchayat and municipality) to promote conservation and maintain People's Biodiversity Registers documenting local bioresources. Sections 3 and 4 require prior approval of the NBA before foreigners, non-resident Indians, or foreign corporations can access biological resources or associated traditional knowledge, or transfer research results, or apply for intellectual property rights such as patents based on Indian bioresources. Indian citizens and entities need only give prior intimation to the relevant SBB under Section 7. The Act exempts normal trade in commodities and local cultivators, vaids, and hakims using bioresources traditionally.

The Act was famously invoked in the bio-piracy disputes over the neem and turmeric patents and, notably, the Bt brinjal case, where the NBA initiated action against Mahyco-Monsanto in 2011 for alleged access to local brinjal varieties without approval. The landmark amendment is the Biological Diversity (Amendment) Act, 2023, which decriminalised offences (replacing imprisonment with monetary penalties adjudicated by Section 24-style proceedings), exempted registered AYUSH practitioners and cultivated medicinal plants from benefit-sharing obligations, and eased compliance for Indian companies registered under domestic law. As of 2026, the amended framework governs access and benefit-sharing, drawing both praise for promoting the AYUSH sector and criticism from conservationists who argue it dilutes biodiversity safeguards.

For the UPSC examination, this Act is a high-frequency theme in General Studies Paper III (Environment and Ecology) and occasionally GS Paper II (statutory bodies). Prelims questions typically test the three-tier structure (NBA–SBB–BMC), the distinction between Section 3 approval for foreigners and Section 7 intimation for Indians, and the linkage with the CBD and Nagoya Protocol. Mains questions probe benefit-sharing, bio-piracy, the 2023 amendment's implications, and the role of People's Biodiversity Registers in decentralised conservation. Candidates should also connect the Act to Articles 48A and 51A(g) of the Constitution.
