Traditional Ecological Knowledge & India's Biodiversity Heritage

Key Concepts

• Traditional Ecological Knowledge (TEK) is the cumulative body of knowledge, practices, and beliefs about the relationship between living beings (including humans) and their environment, evolved by adaptive processes and handed down through generations
• India's TEK is embedded in sacred groves, pastoral traditions, traditional water harvesting systems, indigenous agricultural varieties, and community-managed forests
• The Biological Diversity Act, 2002 provides the legal framework for TEK documentation through People's Biodiversity Registers (PBRs)
• Biopiracy — the patenting of India's traditional knowledge by foreign corporations without benefit-sharing — has been successfully challenged in the turmeric case (1997) and neem case (EPO)
• Relevant for GS-1 (cultural heritage), GS-3 (environment, biodiversity, IPR), and occasionally GS-2 (governance, Biodiversity Act)

What is Traditional Ecological Knowledge (TEK)?

TEK is distinct from conventional scientific knowledge in that it is:

• Localised — developed for specific ecosystems, landscapes, and species
• Oral and practice-based — transmitted through demonstration, ritual, and community memory rather than textbooks
• Holistic — integrates ecological, spiritual, social, and ethical dimensions
• Dynamic — adapted over generations as environments and communities change

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) formally recognises TEK as a "distinct, valued system of knowledge" that complements mainstream science for biodiversity conservation.

Sacred Groves — Community Conservation

Sacred groves (Dev Van, Orans, Kavu) are patches of forest protected by communities on the basis of religious and cultural beliefs.

Sacred groves serve as in situ conservation reservoirs — protecting biodiversity, maintaining watershed functions, and preserving rare and endemic species. India has an estimated 100,000+ sacred groves across the country, forming an informal network of protected areas that predate formal conservation law by millennia.

Pastoral Communities and Transhumance

India's pastoral communities maintain ecological knowledge systems built around seasonal movement (transhumance):

• Van Gujjars (Uttarakhand/Himachal Pradesh): nomadic buffalo herders who move between valley pastures in winter and Himalayan meadows (bugyals) in summer; possess deep knowledge of forest resources and medicinal plants
• Todas (Nilgiri Hills, Tamil Nadu): maintain sacred dairy herds and sacred groves (mund) in the Nilgiri Hills; their knowledge was instrumental in UNESCO's inscription of the Nilgiris as a Biosphere Reserve
• Rabaris (Rajasthan/Gujarat): camel and livestock herders with extensive knowledge of arid-zone ecology

Traditional Water Harvesting Systems

India's pre-modern water management systems represent a sophisticated TEK tradition adapted to diverse regional ecologies:

The johad revival movement in Rajasthan, led by water conservationist Rajendra Singh (Magsaysay Award 2001, Stockholm Water Prize 2015), restored hundreds of johads and revived rivers in the Alwar district — a landmark example of TEK-based ecological restoration.

Traditional Agricultural Varieties and Biodiversity

India is one of the world's mega-biodiverse countries and a Vavilov Centre of Origin for several crop species (rice, mango, sugarcane, among others).

• Indian farmers have maintained over 100,000 varieties of rice over millennia through participatory selection — FAO estimates India has one of the world's richest rice genetic diversities
• Tribal and traditional farming communities maintain diverse seed systems, including drought-resistant, flood-tolerant, and salt-tolerant varieties that are increasingly valued for climate adaptation
• The Protection of Plant Varieties and Farmers' Rights Act (PPV&FR Act), 2001 protects farmers' rights to save, use, sow, resow, exchange, and sell their traditional seed varieties

Biological Diversity Act, 2002 — People's Biodiversity Registers

The Biological Diversity Act, 2002 provides the legal framework for conserving India's biodiversity and TEK:

As of November 2023, India has approximately 268,031 PBRs prepared and 277,688 BMCs constituted across 28 states and 8 Union Territories.

Biopiracy and India's Response

Biopiracy is the appropriation of traditional knowledge and biological resources by corporations or individuals without the permission or fair compensation of the communities that developed them.

Turmeric Case (1997)

• In 1995, the US Patent and Trademark Office (USPTO) granted a patent to the University of Mississippi Medical Center for the use of turmeric in wound healing
• India's CSIR (Council of Scientific and Industrial Research) challenged the patent by submitting documented evidence from ancient Sanskrit texts and modern Indian scientific literature
• USPTO revoked the patent in 1997 — agreeing it was not novel, as turmeric's wound-healing use was well-documented prior art in India
• First successful challenge to a biopiracy patent involving Indian traditional knowledge

Neem Case (EPO)

• The European Patent Office (EPO) granted a patent to W.R. Grace (USA) and the USDA for a method of using neem oil as a fungicide
• A legal challenge was filed by India, the Research Foundation for Science, Technology and Ecology (RFSTE), and IFOAM
• EPO revoked the patent citing lack of novelty and inventive step — neem's anti-fungal properties were documented traditional knowledge

Traditional Knowledge Digital Library (TKDL)

India's response to biopiracy — the TKDL is a digitised, searchable database of over 360,000 formulations from Ayurveda, Unani, Siddha, and Yoga, formatted to meet international patent classification standards so that patent examiners worldwide can identify prior art from Indian traditional knowledge.

Recent Developments (2024–2026)

India's Nagoya Protocol First National Report — ₹216 Crore in Benefit-Sharing (February 2026)

India submitted its first National Report on the Nagoya Protocol to the Convention on Biological Diversity (CBD) in February 2026, covering the period November 2017 – December 2025. The Nagoya Protocol (adopted 2010, in force 2014) operationalises the CBD's third objective of fair and equitable sharing of benefits arising from the use of genetic resources and associated traditional knowledge. India's report revealed that ₹216.31 crore ($28 million) was mobilised through National Biodiversity Authority (NBA) approvals during this period, with ₹139.69 crore disbursed to beneficiaries — including Biodiversity Management Committees (BMCs), local communities, farmers, and traditional knowledge holders. India accounts for over 60% of all International Research Cooperation Certificates issued globally under the Protocol.

At COP16 (Biodiversity Conference of Parties, Cali, Colombia, 2024), a landmark decision established a new permanent subsidiary body for the preservation and protection of indigenous peoples' knowledge, practices, and innovations — ensuring that indigenous and local communities can meaningfully participate in biodiversity governance and benefit-sharing. India actively supported this body's establishment, given the scale of India's traditional ecological knowledge (TEK) systems — from the johad (Rajasthan) to kuhls (Himachal Pradesh) to sacred Dev Van groves. COP16 also made progress on the Kunming-Montreal Global Biodiversity Framework's 30x30 target (protecting 30% of land and oceans by 2030).

UPSC angle: Nagoya Protocol, NBA, Benefit-Sharing, and COP16 outcomes are core GS3 (Environment/Biodiversity) topics. For GS1, the traditional knowledge communities whose practices are being protected — johad builders, sacred grove custodians, kani shawl weavers, tribal practitioners — represent the living continuity of India's ecological heritage. The ₹216 crore benefit-sharing figure demonstrates TKDL and Nagoya Protocol effectiveness.

Forest Rights Act and Community Forest Resource Rights — 22+ Lakh Claims 2024–25

The Forest Rights Act (FRA) 2006 — which recognises tribal and forest-dwelling communities' rights over forest land and resources, including rights over community forest resources (CFRs) which are a core mechanism for community-based TEK conservation — saw 22+ lakh individual forest rights (IFR) and 1.1+ lakh community forest rights (CFR) titles distributed as of 2024–25, per Ministry of Tribal Affairs data. CFRs give village gram sabhas collective governance rights over forest areas where communities have traditionally practised ecological knowledge — sustainable harvesting, forest water harvesting, sacred grove protection, and medicinal plant cultivation.

The IPBES Global Assessment on Indigenous and Local Knowledge (2019 onwards, updated in 2024 reports) formally recognised that TEK-based management systems deliver better biodiversity outcomes than purely scientific approaches in many ecosystems. India's People's Biodiversity Registers (PBRs) — now over 268,031 PBRs across India — document local ecological knowledge, traditional varieties, and conservation practices at the village level, forming a primary database for NBA's benefit-sharing decisions and TKDL's biopiracy prevention.

UPSC angle: FRA 2006 implementation (22+ lakh IFR, 1.1 lakh CFR as of 2024–25) and People's Biodiversity Registers are both GS3 (Environment) and GS2 (Social Justice, Tribal Rights) topics. For GS1, the TEK component — sacred groves, traditional water harvesting, medicinal plant knowledge — links directly to India's cultural heritage and ancient ecological practices tested in UPSC GS1 questions.

PYQ Relevance

• UPSC Prelims: Sacred groves regional names; BD Act 2002 institutions; PBRs definition; biopiracy cases (turmeric, neem)
• GS-3 Mains: "Discuss how traditional ecological knowledge can complement modern conservation efforts in India"
• GS-3: Biopiracy, TKDL, CBD (Convention on Biological Diversity) implementation

Exam Strategy

• Sacred groves: learn at least 4 regional names — Orans (Rajasthan), Dev Van (Uttarakhand), Kavu (Kerala), Sarna (tribal, Jharkhand)
• BD Act institutions: NBA → SBBs → BMCs → PBRs (national to local)
• Biopiracy: Turmeric case = USPTO revoked 1997; Neem case = EPO revoked — both successful for India
• TKDL = preventive tool; PBRs = documentation and community rights
• Johad = check dam (Rajasthan); Kuhl = irrigation channel (Himachal Pradesh) — geography-based questions often test these
