Why this topic matters · 9 min read
Biodiversity Conservation is a high-frequency topic in both UPSC Prelims and Mains. Prelims tests facts about hotspots, protected area categories, conventions, and species classifications. Mains (GS-3) asks for analytical answers on threats, policy responses, and India-specific conservation models. Expect 2-4 Prelims MCQs annually and at least one Mains question every alternate year. Current affairs angles like COP-15 Kunming-Montreal framework, Project Cheetah, and Aichi Targets keep this topic evergreen.
Levels and Types of Biodiversity
Biodiversity exists at three levels: genetic (variation within a species), species (variety of species in an area), and ecosystem (variety of habitats and ecological processes). India is one of 17 mega-diverse countries, hosting about 7-8 percent of recorded species on just 2.4 percent of the world's land area. This disproportionate richness makes India a focal point for conservation discussion.
- Three levels: Genetic, Species, Ecosystem — remember GSE.
- India has 4 of the 36 global biodiversity hotspots: Western Ghats, Eastern Himalayas, Indo-Burma, and Sundaland (Nicobar islands portion).
- Mega-diverse countries are identified by IUCN and Conservation International — India ranks among top 3 in Asia.
- Endemism is a key hotspot criterion: area must have lost over 70 percent of original habitat and have 1500-plus endemic plant species.
- India holds about 45,000 plant species and 91,000 animal species on record.
Threats to Biodiversity
The primary drivers of biodiversity loss are summarized by the acronym HIPPO: Habitat destruction, Invasive species, Pollution, Population (human overuse), and Over-exploitation. Climate change is now often added as a sixth driver. In India, habitat fragmentation due to infrastructure expansion, poaching of tigers and elephants, and invasive species like Lantana camara in forest understories are the most visible threats.
- Habitat loss is the single biggest threat globally and in India — drives 80 percent of species declines.
- Invasive alien species: Lantana camara, Water Hyacinth (Eichhornia), Parthenium are top Indian examples.
- Overexploitation includes illegal wildlife trade — India is both a source and transit country.
- Pollution: pesticide runoff causes bee colony collapse; industrial discharge harms aquatic biodiversity.
- Climate change is shifting species ranges poleward and upward — disrupts phenological cycles.
In-situ Conservation
In-situ means conserving species in their natural habitat. India's protected area network is the backbone of in-situ conservation. It includes National Parks, Wildlife Sanctuaries, Conservation Reserves, and Community Reserves under the Wildlife Protection Act 1972. Biosphere Reserves are managed under UNESCO's Man and Biosphere programme and allow limited human use in buffer and transition zones.
- India has 106 National Parks, 567 Wildlife Sanctuaries, 97 Conservation Reserves, 220 Community Reserves (approx. as of 2024).
- National Park: highest protection, no human activity permitted, boundaries fixed by legislature.
- Wildlife Sanctuary: some human activity allowed, boundaries can be altered by state government.
- Biosphere Reserve: core zone (strict), buffer zone (research), transition zone (human use) — think three concentric circles.
- 18 Biosphere Reserves in India; 12 are under UNESCO World Network of Biosphere Reserves.
- Ramsar Sites (wetlands of international importance) — India has 75-plus Ramsar sites, highest in Asia.
- Tiger Reserves under Project Tiger (1973) are governed by NTCA — India has 54 Tiger Reserves.
Ex-situ Conservation
Ex-situ means conserving species outside their natural habitat. This is a backup strategy when wild populations are critically low. Methods include zoos, botanical gardens, seed banks, cryopreservation, and tissue culture. India's National Bureau of Plant Genetic Resources (NBPGR) maintains one of the world's largest seed gene banks. Ex-situ is complementary to in-situ, not a replacement.
- Seed banks: NBPGR in New Delhi stores over 4 lakh seed accessions.
- Zoological parks under Central Zoo Authority — three categories: large, medium, mini zoos.
- Cryopreservation stores genetic material at very low temperatures for future use.
- Botanical gardens: Indian Botanical Garden, Howrah is the oldest and largest.
- Captive breeding programs: gharial, red panda, snow leopard.
- Gene banks for livestock breeds maintained by NBAGR (National Bureau of Animal Genetic Resources).
Key International Conventions and Frameworks
UPSC frequently tests the provisions and conference outcomes of international biodiversity agreements. The Convention on Biological Diversity (CBD, 1992, Rio Earth Summit) is the overarching framework with three objectives: conservation, sustainable use, and fair sharing of benefits from genetic resources (Access and Benefit Sharing — ABS). The Nagoya Protocol (2010) operationalized ABS. The Kunming-Montreal Global Biodiversity Framework (COP-15, 2022) set the landmark 30x30 target.
- CBD adopted at Rio 1992, entered into force 1993 — USA is a notable non-party.
- Cartagena Protocol (2000): covers safe transfer of Living Modified Organisms (LMOs) — biosafety.
- Nagoya Protocol (2010): Access and Benefit Sharing from genetic resources — India ratified 2012.
- Aichi Biodiversity Targets (2010-2020, Nagoya): 20 targets in 5 strategic goals — largely unmet globally.
- Kunming-Montreal Framework (COP-15, 2022): 30x30 target — 30 percent of land and oceans protected by 2030.
- CITES: controls international trade in endangered species — three appendices based on threat level.
- Ramsar Convention (1971): focused on wetland conservation — oldest modern environmental convention.
India-Specific Conservation Legislation and Programs
India's domestic legal framework is robust on paper. The Wildlife Protection Act 1972 is the primary law; it was significantly amended in 2022. The Biological Diversity Act 2002 implements CBD commitments and establishes the National Biodiversity Authority (NBA). Project Tiger (1973) and Project Elephant (1992) are flagship species recovery programs. India's forest-dwelling communities are protected under the Forest Rights Act 2006, which UPSC links to conservation versus livelihood tension.
- Wildlife Protection Act 1972: Schedules I-IV list protected species — Schedule I gets highest protection.
- 2022 Amendment restructured schedules from 6 to 4 and gave NTCA statutory powers.
- Biological Diversity Act 2002: NBA at national level, State Biodiversity Boards, local Biodiversity Management Committees.
- Project Tiger: 54 reserves, India holds 70 percent of world's wild tigers — 3682 tigers in 2022 census.
- Project Elephant: 33 Elephant Reserves, elephant corridors are a major conservation-conflict issue.
- Project Cheetah (2022): reintroduction of African cheetahs into Kuno National Park — first intercontinental translocation.
- Forest Rights Act 2006: grants land and forest rights to Scheduled Tribes and Other Traditional Forest Dwellers.
⚠ Common mistakes to avoid
- Confusing National Park and Wildlife Sanctuary: remember, in a National Park even the boundary cannot be changed without Parliament's approval; in a Sanctuary it can be changed by the state government.
- Mixing up Cartagena Protocol (biosafety, LMOs) with Nagoya Protocol (Access and Benefit Sharing) — both are under CBD but address entirely different issues.
- Thinking all Biosphere Reserves are Ramsar Sites or UNESCO World Heritage Sites — they are separate designations with separate criteria.
- Stating that CITES bans all trade in listed species — Appendix I bans trade, but Appendix II allows regulated trade and Appendix III is a national listing request.
- Confusing Aichi Targets (2010-2020, largely failed) with Kunming-Montreal 30x30 targets (2022-2030, current framework) — UPSC expects you to know both and distinguish them.
🧠 Memory aids
- HIPPO for threats: Habitat loss, Invasive species, Pollution, Population pressure, Over-exploitation — imagine a HIPPO destroying a forest.
- GSE for biodiversity levels: Genetic, Species, Ecosystem — think of it as zooming out from DNA to forest.
- For hotspots remember WEIS: Western Ghats, Eastern Himalayas, Indo-Burma, Sundaland — four corners of India (roughly).
- CBD's three goals: CSA — Conservation, Sustainable use, Access and benefit sharing — think of it as a CSA (Community Supported Agriculture) giving back to nature.
- 30x30 for Kunming-Montreal: Thirty percent protected by 2030 — same number repeated twice makes it easy.
🎯 UPSC CSE exam tips
- Prelims frequently asks which species is under which CITES Appendix or which Schedule of WPA — make a quick table: tiger, elephant, snow leopard are all Schedule I and CITES Appendix I.
- For Mains, the examiner expects you to link conservation with tribal rights (FRA 2006) and the conservation vs development debate — avoid one-sided answers; show balance between ecological security and livelihood.
- Recent Prelims (2022, 2023) asked about Ramsar sites added from India, and about the Kunming-Montreal framework — stay current with each year's additions.
- Questions on Project Cheetah often appear as a statement-based MCQ testing whether African cheetah or Asiatic cheetah was introduced — it is African cheetah (Namibia and South Africa), as Asiatic cheetah is critically endangered in Iran.
- In Mains answers on biodiversity, use the DPSIR framework (Drivers, Pressures, State, Impact, Response) as a structure — it signals analytical thinking to the examiner.

Q4 · hard · AI-verified
Which of the following best explains why 'biodiversity hotspots' are considered both important for conservation AND paradoxically vulnerable?
- They are located exclusively in tropical regions and receive excessive rainfall, making them unsuitable for human habitation but prone to flooding.
- They contain the highest number of migratory species, which makes conservation difficult as the species cross multiple national jurisdictions.
- They harbour exceptional concentrations of endemic species but have already lost at least 70% of their original primary vegetation.
- They are vulnerable because they are entirely marine ecosystems exposed to ocean acidification, despite being rich in coral reef biodiversity.
