Biosphere Reserves in India

1. At a Glance

• A Biosphere Reserve (BR) is an area identified by national governments to conserve biodiversity and promote sustainable development. It links protected ecosystems with the communities living around them. [1]
• The concept comes from UNESCO's Man and the Biosphere (MAB) Programme (1971). BRs work as "living laboratories" for testing sustainable development. [1]
• India has 18 notified BRs covering 91,425 sq km. 13 of them are in UNESCO's World Network of Biosphere Reserves (WNBR), the highest number in South Asia. [1][4]
• UPSC relevance: the topic is a regular Prelims map and match-the-pair area, and fits GS-III (conservation) and GS-II (federal funding of CSS) in Mains.

2. Why in the News

• International Day for Biosphere Reserves (3 November), proclaimed by UNESCO. PIB issued a backgrounder on India's 18-reserve network for it. [1]
• 27 September 2025: the Cold Desert BR (Himachal Pradesh) became India's 13th WNBR site. It was one of 26 new sites added at the 5th World Congress of Biosphere Reserves, Hangzhou (China). [2][3]
• Integrated Management Plans (IMPs) have been piloted since 2022–23 for four BRs. [1]

3. Background & Evolution

• 1971: UNESCO launched the MAB Programme to bring a scientific approach to how people relate to their environment. [1]
• 1986: India started its Biosphere Reserve programme. Nilgiri became the first BR, set up under the Indian National MAB Programme. [5][7]

• The notification date is uncertain: one source gives 1.9.1986 [5] and another gives 1.8.1986 [7].

• 28.07.1997: Dibru-Saikhowa (Assam) was notified. [7]

• 2000: Nilgiri became India's first BR recognised by UNESCO. [6]
• 2009: Cold Desert BR was notified nationally. [1]
• 2020: Panna (Madhya Pradesh) joined the WNBR as India's 12th site. [8][9]
• 2022–23 onwards: five-year Integrated Management Plans were piloted. [1]
• 2025: Cold Desert became the 13th WNBR site. [1][3]

4. Core Static Facts

Three functions [1]

• Conservation: biodiversity, genetic resources, ecosystems, landscapes and cultural diversity.
• Sustainable economic development: activities within ecological limits and local cultural values.
• Scientific support (logistic function): research, monitoring, education and training.

Zonation (global average split: 18% core / 30% buffer / 52% transition) [1]

• Core: strictest protection. Only compatible research and monitoring are allowed.
• Buffer: environmental education, research and regulated ecotourism. It reduces pressure on the core.
• Transition: settlements, livelihoods, responsible agriculture and sustainable forestry.

Biodiversity levels (CBD definition) [1]

• Genetic diversity: variation within a species, e.g. rice varieties.
• Species diversity: the range of species.
• Ecosystem diversity: forests, grasslands, wetlands, coral reefs.

Cold Desert BR profile [3]

• Area: 7,770 km², at 3,300–6,600 m altitude.
• Includes Pin Valley NP, Chandratal, Sarchu and Kibber WLS.
• Population: about 12,000.
• UNESCO calls it India's first high-altitude cold-desert BR.

5. Multi-Dimensional Analysis

Environmental

• BRs conserve at three levels: genes, species and ecosystems. They support food security, water availability and climate resilience. [1]
• The zones shift from strict protection to managed use. This gives a landscape-level alternative to "fortress" protected areas. [1]
• Cold Desert adds a high-altitude cold-arid ecosystem to the WNBR. Before it, India's WNBR sites were mostly forest and coastal ecosystems. [3]

Social / Tribal

• The transition zone formally recognises settlements and livelihoods inside the reserve. [1]
• Lantana crafts (Nilgiri): indigenous communities make crafts from removed Lantana camara. This turns an invasive weed into income for artisans and raises awareness of invasive species. [1]
• Women for Bees (Nilgiri): a UNESCO initiative linking women's empowerment with biodiversity. [6]

Economic

• Regulated ecotourism in buffer zones and sustainable forestry and agriculture in transition areas earn income for local people while keeping ecosystems intact. [1]
• Community enterprises such as Lantana crafts show that conservation can earn money. [1]

Administrative / Federal

• Funding is a CSS with Centre–State sharing (60:40, or 90:10 for NE and Himalayan States). This means States' fiscal capacity and Forest Department capacity shape what gets done. [1]
• IMPs bring together reserve authorities, research institutions and local communities. Their priorities are habitat restoration, monitoring, research and livelihoods. [1]
• UNESCO may approve WNBR entry subject to documents being submitted, so national reporting quality matters. [10]

Legal

• National Parks and Wildlife Sanctuaries mainly protect wildlife and habitats under wildlife protection laws. BRs take a broader, community-linked approach. [1]
• Analytical point (no source): BRs are mainly an administrative and programmatic designation. Strict legal protection usually comes from the national parks or sanctuaries inside the core.

Geopolitical / Multilateral

• India has the most WNBR sites in South Asia (13). This supports its standing as a mega-biodiverse country and its record under the CBD. [1]

6. Recent Developments (last 12–18 months)

• 27 September 2025: UNESCO's 37th MAB International Coordinating Council session took place during the 5th WCBR in Hangzhou. Cold Desert was inscribed as India's 13th WNBR site. [2][3]
• August 2025: UNESCO's advisory committee document recommended approving new BRs subject to documents being submitted. [10]
• November 2025: PIB published the backgrounder "Sustaining Life, Celebrating Nature: India's Biosphere Reserves". It gives 18 BRs, 91,425 sq km and 13 in the WNBR. [4]
• 3 November (International Day for Biosphere Reserves): PIB backgrounder on the BR concept, the CSS funding pattern and the four IMP pilot reserves. [1]
• IMP pilots (since 2022–23): Nanda Devi, Pachmarhi, Dehang-Dibang, Agasthyamalai. [1]

7. Prelims Hooks

• India has 18 notified BRs. 13 are in UNESCO's WNBR. [1]
• India has the highest number of WNBR sites in South Asia. [1]
• UNESCO launched the MAB Programme in 1971. [1]
• India started its BR programme in 1986. Nilgiri was the first BR. [5][7]
• Nilgiri was the first Indian BR in the WNBR, in 2000. [6]
• Cold Desert BR (Himachal Pradesh) was notified in 2009 and joined the WNBR in 2025 as India's 13th site. [1][3]
• Cold Desert was inscribed at the 5th World Congress of BRs, Hangzhou, China. [3]
• Panna (MP) became India's 12th WNBR site in 2020. [8][9]
• Largest BR: Great Rann of Kutch, Gujarat (12,454 sq km). [4]
• Global average zone split: 18% core, 30% buffer, 52% transition. [1]
• The scheme is "Biodiversity Conservation", a CSS under the umbrella "Conservation of Natural Resources and Ecosystems". [1]
• Funding is 60:40, or 90:10 for NE and Himalayan States. [1]
• The Biosphere Reserve Division of MoEFCC administers the scheme. State Forest Departments implement it. [1]
• IMP pilot BRs are Nanda Devi, Pachmarhi, Dehang-Dibang and Agasthyamalai. [1]
• India holds about 7–8% of recorded species on 2.4% of global land area. [1]

8. Why a Biosphere Reserve Has No Law of Its Own

• A biosphere reserve is a scheme, not a legal category
• In Parliament, the government describes the Biosphere Reserve programme as a scheme that has run since 1986, with money given to States [11].
• No Indian statute (an Act passed by Parliament) creates a "biosphere reserve" the way the Wildlife (Protection) Act, 1972 creates a National Park or a Wildlife Sanctuary.

• So the strict protection in the core comes from the National Park or Sanctuary that already sits inside it, not from the biosphere reserve label [1].

• The buffer and transition zones are the weak part

• These two zones hold the ecotourism, farming and settlements that the BR model depends on [1].
• Since the BR label carries no penalties, rules in these zones must come from other tools. One example is Eco-Sensitive Zones (regulated belts around protected areas) under the Environment (Protection) Act.

• Where no such tool applies, the zoning map only guides decisions. It does not bind anyone.

• The UNESCO tag does not add legal force either

• PIB itself notes that biosphere reserves "remain under the sovereign jurisdiction" of the country where they lie [17].
• A country can leave the World Network just by informing the MAB Secretariat [12].
• UNESCO can review a site and name it publicly. It cannot stop a road or a mine inside it.

9. Plans on Paper, but Little Data and Late Money

• Monitoring needs baseline data first, and some reserves did not have it
• Baseline data is the first measurement of an ecosystem. Without it, nobody can say whether things are getting better or worse.
• A CAG performance audit found that the Gulf of Mannar Biosphere Reserve kept no baseline data on its coral reefs until 2018 [15].
• The first baseline survey was done only in 2019, and the money came from a separate national climate adaptation fund [15].

• A reserve set up to protect a marine ecosystem therefore ran for years without measuring that ecosystem.

• Under a CSS, if the Centre's money is late, the State's money cannot be spent either

• CSS (Centrally Sponsored Scheme) means the Centre and the States share the cost: 60:40 here, or 90:10 for NE and Himalayan States [1].
• A CAG State Finances audit found that the entire budget provision for the Similipal Biosphere Reserve was surrendered (returned unspent) because the funds were never released [16].

• So a delay at one level of government stops the work at both levels.

• Exam precision on the 90:10 ratio

• The Minister's Lok Sabha reply says 90:10 applies to the NE States and three Himalayan States [11].

• That is narrower than "all hill States". It sharpens the trap already listed in the note's Section 10.

• Only 4 of the 18 reserves have the new management plan

• Integrated Management Plans (IMPs) are being piloted only in Nanda Devi, Pachmarhi, Dehang-Dibang and Agasthyamalai [1].
• The other 14 reserves are not yet in this pilot.

10. What the UNESCO Tag Gives, and How a Country Can Lose It

• The tag comes with a test every ten years
• UNESCO reviews each biosphere reserve every 10 years. This is called the periodic review [12].
• It checks whether the site still works as a reserve: its zoning, its size, and how far local communities are involved [12].

• This outside check is the main thing the WNBR adds. It gives India no extra money and no extra legal power.

• Many old reserves around the world have failed this test

• 61 sites from 14 countries have been withdrawn from the World Network [12].
• Many were designated in the 1970s and 1980s. They could not meet UNESCO's newer rules (the Seville Strategy), for example the rule that people must live and work in the transition zone [12].

• Even large countries leave: in 2024 the MAB Council approved requests from the United States and Bulgaria to withdraw some of their reserves [13].

• UNESCO is now pushing harder

• UNESCO's draft Hangzhou Strategic Action Plan (2026–2035) refers to an "exit strategy". Under it, every reserve must either work fully under the Statutory Framework or leave the network voluntarily [14].

• India's older WNBR sites, such as Nilgiri (listed in 2000) [6], will be judged on how they work today, not on how they were designed.

• Getting the tag is slow

• An earlier Lok Sabha reply said 12 Indian reserves were in the WNBR and 6 were "under consideration" [11].
• Since then only one more, Cold Desert, has been added. It was notified in 2009 and listed in 2025, a gap of 16 years [1][3].
• UNESCO approves new sites "subject to documents being submitted" [10]. So weak paperwork and missing monitoring data (see the Gulf of Mannar case above) slow India down.

11. Is "Conservation With People" Real or Just a Label?

• The strongest objection
• Critics can say a biosphere reserve only draws a new line around National Parks that already exist.
• It gives no new legal protection (see the first section) and depends on a small CSS that States may not be able to match [1][16].

• On this view, the "people-friendly" image is a label, while the real protection is still the old fortress-style National Park in the core.

• What is right about it

• The legal point is correct. The core's protection is borrowed from the Wildlife (Protection) Act, not created by the BR [1].

• The money point is also fair. The Similipal surrender shows that CSS funds can fail to arrive [16].

• Why the model still has value

• It plans for the whole landscape, including villages and farms. That is something a National Park cannot do legally.
• It provides a 10-year outside review that no Indian law on protected areas provides [12].

• Community enterprises, such as Lantana crafts in Nilgiri, show that the transition zone can produce real income [1].

• Balanced line for an answer: biosphere reserves add a planning and review layer, not a protection layer. Their value depends on whether States fund and use that layer.

12. What MoEFCC and the States Should Do Next

• The MoEFCC Biosphere Reserve Division should require baseline surveys before extending IMPs
• The CAG's Gulf of Mannar finding shows that plans without baseline data cannot be checked [15].

• Every new IMP, beyond the four pilots, should start with a measured baseline of the ecosystem it protects [1].

• Run India's own review before UNESCO does

• UNESCO's 10-year periodic review and the draft Hangzhou "exit strategy" will test India's 13 WNBR sites [12][14].

• The Indian National MAB Committee [7] could use the same checklist (zoning, community role, monitoring) on all 18 reserves. Weak sites would then be fixed before they are named in a UNESCO review.

• Release Central funds on time so the State share is not lost

• In a CSS, a late Central release can make the whole State provision lapse, as happened at Similipal [16].

• The Ministry could release funds on a fixed calendar linked to each reserve's approved annual plan.

• Give the buffer and transition zones legal backing where they are under pressure

• States and MoEFCC can line up BR buffer boundaries with notified Eco-Sensitive Zones under the Environment (Protection) Act.
• Then the zoning map will have rules that can actually be enforced.

13. Anchors for Answers

• Data: 18 notified BRs (91,425 sq km), only 13 in UNESCO's WNBR [4]; 61 biosphere reserves from 14 countries withdrawn from the World Network so far [12]
• Report/Committee: CAG Performance Audit on Conservation of Coastal Ecosystems found no coral baseline data at Gulf of Mannar BR till 2018 [15]; CAG State Finances Audit showed the full Similipal BR provision surrendered because funds were not released [16]
• Law/Case: No BR-specific statute exists; core protection comes from National Parks and Sanctuaries under the Wildlife (Protection) Act, 1972 [1]; Eco-Sensitive Zones under the Environment (Protection) Act, 1986
• Comparison: USA and Bulgaria withdrew reserves in 2024 [13]; UNESCO's draft Hangzhou Strategic Action Plan 2026–35 sets an "exit strategy" for reserves that do not function [14]
• Scheme: "Biodiversity Conservation" CSS under "Conservation of Natural Resources and Ecosystems" (60:40; 90:10 for NE and three Himalayan States) [1][11]; IMPs piloted in 4 BRs since 2022–23 [1]

14. Mains Relevance

• GS-III: Conservation, environmental pollution and degradation, environmental impact assessment. Also biodiversity and in-situ conservation.
• GS-II: Government policies and interventions; Centre–State fiscal relations through CSS cost sharing; important international institutions (UNESCO).
• GS-I: Distribution of key natural resources; physical geography of biogeographic zones.
• Possible question stems: 1. Biosphere reserves represent a shift from 'fortress conservation' to 'conservation with people'. Discuss with reference to the zonation model and Indian examples. (15 marks) 2. Only 13 of India's 18 biosphere reserves are in UNESCO's World Network. What does international recognition add, and what limits the effectiveness of biosphere reserves in India? (10 marks) 3. How do community-based initiatives inside biosphere reserves reconcile livelihoods with conservation? Illustrate with examples. (10 marks)

15. Related Topics to Study Next

• Protected Areas under the Wildlife (Protection) Act, 1972 (NP, WLS, Conservation and Community Reserves): needed for the BR vs PA distinction.
• UNESCO World Heritage Sites (natural): a different UNESCO list that is easy to confuse with the WNBR. Some sites appear on both (e.g. Nanda Devi, Sundarbans).
• Ramsar Sites: another international designation that overlaps BR geography.
• Convention on Biological Diversity and the Kunming-Montreal GBF (30x30): BRs count toward area-based conservation targets.
• Biodiversity Act, 2002 and the 2023 amendment: the statutory biodiversity governance framework (NBA, SBBs, BMCs).
• Invasive alien species (Lantana, Prosopis): connects to the Nilgiri Lantana-craft example.
• Eco-Sensitive Zones: a buffer-type regulatory tool under the EP Act around PAs.
• Biogeographic zones of India: BR locations map onto them (Desert, Himalaya, Western Ghats, and others).

16. NCERT Concepts to Revise

• Biosphere reserve (Geography): The core topic: the core, buffer and transition zones and how a reserve differs from a national park.
• Man and Biosphere Programme (Geography): UNESCO's 1971 programme behind the World Network, the 10-year review and India's 13 listed sites.
• Centrally sponsored schemes (Economy): BR funding is a 60:40 Centre-State scheme, and late Central money stalled work at Similipal.
• Wildlife (Protection) Act 1972 (Geography): Core-zone protection comes from national parks and sanctuaries under this Act, not from the BR label.
• Environment Protection Act 1986 (Geography): Eco-Sensitive Zones under this Act are suggested as the way to give buffer zones enforceable rules.
• Nilgiri Biosphere Reserve (Geography): India's first BR (1986) and first on UNESCO's list (2000); also the Lantana-craft example.

17. Common Errors / Trap Areas

• Notified vs WNBR: 18 notified ≠ 13 UNESCO-recognised. The five not in the WNBR are a frequent elimination-style question. Cold Desert was notified in 2009 but reached the WNBR in 2025. Don't mix up the two years. [1]
• Smallest BR conflict: PIB 2025 names Nokrek (820 sq km) [4], but an older MoEF table lists Dibru-Saikhowa at 765 sq km [7]. Check the latest MoEFCC list before the exam.
• Global count conflict: PIB gives 797 BRs in 145 countries [1], while UNESCO gave 785 at the September 2025 congress [3]. The number keeps changing, so quote it with its date.
• Nilgiri dates: national designation in 1986 vs WNBR entry in 2000 [5][6]. The exact 1986 notification date also differs between sources (1.8.86 vs 1.9.86). [5][7]
• Activities by zone: ecotourism and education belong to the buffer; settlements and agriculture belong to the transition area. The core allows only research and monitoring. [1]
• Funding ratio: 90:10 applies to NE and Himalayan States, not to all special-category or hill areas generally. Also, the scheme is a CSS, not a Central Sector scheme. [1]
