UNESCO’s Man and the Biosphere (MAB) Programme
Launched 1971 · “Living laboratories for sustainable development” · 785 sites in 142 countries
💡 Biosphere Reserve = A Graduated Hospital Ward for the Entire Ecosystem
Unlike a National Park (ICU — no human entry) or a Wildlife Sanctuary (general ward — limited activity), a Biosphere Reserve is like a full residential health campus. People live and work inside it. The innermost zone is the ICU (Core — no disturbance). The middle zone is the treatment zone (Buffer — controlled research/tourism). The outer zone is where residents go about daily life under careful guidance (Transition — human settlements, sustainable farming, traditional practices). The philosophy: “People are not separate from nature — conservation works best when local communities are partners, not obstacles.”
UNESCO MAB Programme — Key Facts
- Launched: 1971 by UNESCO | An intergovernmental scientific programme
- Objective: “To establish a scientific basis for the improvement of relationships between people and their environments” | Promotes conservation of biodiversity + sustainable use of natural resources + improvement of human well-being
- World Network of Biosphere Reserves (WNBR): 785 sites in 142 countries as of 2025 — the 5th World Congress of Biosphere Reserves (September 2025, Hangzhou, China) added 26 new sites (highest number in 20 years)
- Three functions of a BR (key for UPSC):
- Conservation: Protecting biodiversity and cultural diversity
- Development: Promoting economic and social development that is socioculturally and ecologically sustainable
- Logistic support: Supporting demonstration projects, environmental education, research and monitoring
- Designation process: Country nominates → UNESCO’s International Coordinating Council (ICC-MAB) reviews → UNESCO recognizes | National BRs can exist without UNESCO recognition (India has 18 national BRs, 13 UNESCO-recognized)
- India’s BR scheme: Government of India launched the Biosphere Reserve scheme in 1986 under the UNESCO MAB Programme | India is a signatory to the MAB landscape approach
- Funding in India: 90:10 Central:State ratio for NE Region States + 3 Himalayan states | 60:40 for other states | Management Action Plans prepared by State Government and approved by Central MAB Committee
- Difference from Protected Area: BRs are UNESCO designations — NOT legal categories under India’s WPA 1972. A BR can overlap with NPs, WLS, Tiger Reserves, Ramsar Sites — same geographical area can have multiple designations simultaneously. Example: Manas is simultaneously UNESCO WHC + Tiger Reserve + Biosphere Reserve + National Park + Ramsar Site.
- 50th anniversary: 2025 marks the 50th anniversary of UNESCO’s MAB Programme — celebrated at 5th World Congress of Biosphere Reserves, Hangzhou, China (September 2025)

The Three-Zone Model — Structure of a Biosphere Reserve
Core → Buffer → Transition — from maximum protection to sustainable human use
🔵 CORE ZONE — Inviolate Nucleus
Strictly protected | Legally corresponds to a National Park or Sanctuary (under WPA 1972) | Minimal human disturbance | Scientific monitoring permitted | No extraction of resources | Contains most sensitive biodiversity | Only research with special permits | Example: In Nilgiri BR, the core = Silent Valley NP + Mudumalai NP + other NPs
🟣 BUFFER ZONE — Controlled Use Area
Surrounds the core | Scientific research, education, eco-tourism, low-impact activities allowed | No permanent settlements in most cases | Acts as a transition between the strict core and human-inhabited transition zone | Must not impair core zone conservation | Corresponds to Wildlife Sanctuaries in most cases
⬜ TRANSITION ZONE (Cooperation Zone)
Outermost zone | Human settlements, traditional use of resources, sustainable agriculture, eco-friendly tourism, fishing allowed | Local communities live here | Demonstrates how human activities and conservation can coexist | Where indigenous/traditional knowledge is practiced | Also called the “zone of cooperation” — communities are active partners
BR Zones vs Protected Area Legal Framework — UPSC Key Comparisons
- BR is NOT a legal category: Unlike National Parks or Wildlife Sanctuaries, a Biosphere Reserve is NOT declared under any specific section of the WPA 1972. It is a UNESCO/MoEFCC administrative designation overlaid on existing PAs.
- Core zone ≈ National Park/Sanctuary: The core of a BR usually corresponds to an existing NP or WLS with full legal protection. E.g., Nanda Devi NP forms the core of Nanda Devi BR.
- BRs are always larger than NPs: Because they include the buffer and transition zones around the existing NP/WLS. The BR encompasses much more land than the NP at its core.
- Multiple overlapping designations: Sundarbans = NP + Tiger Reserve + BR + UNESCO WHC + Ramsar Site — all simultaneously. Each designation adds different conservation obligations and funding streams.
- NP → cannot have human habitation: But the same area can be part of a BR’s transition zone where communities live. This is how BRs incorporate human wellbeing more explicitly.

All four statements are factually accurate and represent the key current affairs from the 5th World Congress of Biosphere Reserves (WCBR) in Hangzhou, China. 1 ✅ 13th UNESCO BR, Sept 27, 2025: UNESCO officially announced the designation during the 37th Session of UNESCO’s International Coordinating Council — Man and the Biosphere (ICC-MAB), held on September 27, 2025. Environment Minister Bhupender Yadav confirmed: “India now has 13 biospheres listed in UNESCO’s World Network of Biosphere Reserves.” The Cold Desert had been nationally designated as a BR since 2009 — but UNESCO recognition came only in 2025. 2 ✅ Lahaul-Spiti, Himachal Pradesh: The Cold Desert BR is located in Lahaul-Spiti district of HP — in the Trans-Himalayan biogeographic province. This is the cold desert region BEHIND the main Himalayan ranges (on the rainshadow side), receiving very little precipitation and experiencing extreme temperatures. 3 ✅ Pin Valley NP + Kibber WLS: The key protected areas within the Cold Desert BR include: Pin Valley National Park (core area), Kibber Wildlife Sanctuary (core area), Chandratal Wetland, and Sarchu Plains. Altitude range: 3,300–6,600 metres. Total area: 7,770 sq km (Core: 2,665 sq km, Buffer: 3,977 sq km, Transition: 1,128 sq km). 4 ✅ First Indian high-altitude cold desert BR in UNESCO WNBR: UNESCO itself called it “India’s first high-altitude cold desert biosphere reserve and one of the coldest and driest ecosystems in UNESCO’s World Network of Biosphere Reserves.” The 50th anniversary of the MAB Programme was also celebrated at the same WCBR event.
Q2. Consider the following statements about Biosphere Reserves in India:
1. The Nilgiri Biosphere Reserve, established in 1986, was India’s first biosphere reserve and also the first to receive UNESCO recognition (in 2000).
2. The Gulf of Mannar Biosphere Reserve was India’s first marine biosphere reserve.
3. The Achanakmar-Amarkantak Biosphere Reserve is the source of both the Narmada River (flowing to the Arabian Sea) and the Son River (flowing to the Bay of Bengal).
4. Khangchendzonga National Park is the core of the Khangchendzonga Biosphere Reserve and is also India’s only Mixed UNESCO World Heritage Site.
Select ALL correct statements:
✅ Answer: (d) All four are correct
1 ✅ Nilgiri = First BR + First UNESCO: The Nilgiri Biosphere Reserve was notified in 1986 as India’s first BR. It spans TN, Karnataka, and Kerala in the Western Ghats — covering Silent Valley NP, Mudumalai NP, Nagarhole NP, Bandipur NP, Mukurthi NP, and several WLS. It was the first Indian BR to receive UNESCO recognition in 2000. “Nilgiri” = Blue Mountain — named after Neelakurinji flowers that bloom once every 12 years. 2 ✅ Gulf of Mannar = First Marine BR: The Gulf of Mannar BR (Tamil Nadu, 1989) was India’s first marine biosphere reserve. It is located between India and Sri Lanka, comprising 21 islands surrounded by coral reefs, seagrass beds, mangroves, and salt marshes. India’s only natural habitat for Dugong (VU) — the “sea cow” that feeds on seagrass — is in this BR. UNESCO recognized it in 2001. 3 ✅ Achanakmar-Amarkantak = Two-ocean watershed: This BR (MP + Chhattisgarh) is geographically unique: the Amarkantak plateau is the source of the Narmada River (which flows westward and drains into the Arabian Sea) AND the Son River (which flows eastward and drains into the Bay of Bengal at the Ganga). From one plateau, water flows to two different seas — a remarkable drainage divide. Achanakmar-Amarkantak BR was UNESCO recognized in 2012. 4 ✅ Khangchendzonga = Only Mixed WHC: Khangchendzonga NP is India’s only Mixed UNESCO World Heritage Site (2016) — inscribed for BOTH natural (Eastern Himalayan biodiversity, Snow Leopard, Red Panda, Mt Khangchendzonga 8,586m — world’s 3rd highest) AND cultural (Lepcha + Bhutia indigenous sacred traditions linked to the mountain). The Khangchendzonga BR received UNESCO recognition in 2018.
📜 UPSC Previous Year Questions (PYQs)
The most important strategy for the conservation of biodiversity together with traditional human life is the establishment of:
(a) Biosphere reserves
(b) Botanical gardens
(c) National parks
(d) Wildlife sanctuaries
✅ Official Answer: (a) Biosphere Reserves
This is a conceptually important PYQ that tests understanding of why BRs are uniquely suited to combine biodiversity conservation WITH traditional human life — which no other category does as explicitly. Why Biosphere Reserves (and not others): National Parks and Wildlife Sanctuaries prohibit or severely restrict human habitation and traditional activities. They essentially exclude local communities from conservation. Botanical Gardens preserve plant species ex situ (outside natural habitat) — not with traditional human communities. Biosphere Reserves are uniquely designed to include the Transition/Cooperation Zone where local communities (including traditional/indigenous communities) continue to practice their traditional livelihoods — farming, herding, fishing, traditional medicine, forest product collection — while contributing to conservation. The philosophy is: traditional knowledge and practices developed over centuries are assets for conservation, not obstacles. The Sowa Rigpa (Tibetan medicine) practitioners in Cold Desert BR, the Bishnoi community near Tal Chhapar, the fisherfolk of Chilika Lake, the Shompen tribe in Great Nicobar — all are integral to the BR management as “knowledge partners.” BRs explicitly recognise that conservation and human culture are not mutually exclusive. This is why BRs are the BEST answer for “conservation together with traditional human life.” The 2014 UPSC exam correctly identified this as the answer.
Consider the following pairs:
National Park — State
1. Dampa Tiger Reserve — Mizoram
2. Gumti Wildlife Sanctuary — Sikkim
3. Saramati Peak — Nagaland
How many of the above pairs are correctly matched?
✅ Official Answer: (d) All three pairs are correctly matched
1 ✅ Dampa Tiger Reserve — Mizoram: Dampa Tiger Reserve is located in Mizoram, western Mizoram near the Bangladesh border. It is one of India’s 58 Tiger Reserves and is among the TRs with zero tigers recorded in the 2022 census — a conservation concern. Area: ~500 sq km. It covers the Lushai Hills (Mizo Hills) in southwestern Mizoram. Correct: Dampa is in Mizoram. 2 ✅ Gumti Wildlife Sanctuary — Sikkim: Gumti Wildlife Sanctuary (also called Kyongnosla Alpine Sanctuary) is in Sikkim. It is located along the Nathu La road near Gangtok. It protects Red Pandas, Rhododendrons, and other alpine species. Note: Do not confuse with the Gumti reservoir/river in Tripura (different state). This specific WLS is in Sikkim — the question is correctly paired. 3 ✅ Saramati Peak — Nagaland: Saramati (also spelled Sharamati) is the highest peak in Nagaland at approximately 3,826 metres above sea level. Located in the Tuensang district of Nagaland, near the Myanmar border. It is the highest point in Nagaland and one of the highest peaks in NE India. The Saramati Peak Wildlife Sanctuary surrounds this peak. Correct: Saramati is in Nagaland.
This is the most common conceptual confusion in this topic — and UPSC has tested it multiple times. National Park: A legal category under India’s Wildlife Protection Act, 1972 (Section 35). Declared by Central or State Government. Strictly protected — no human activities, all rights extinguished inside. ~44,400 sq km, 107 NPs. Legal protection, managed by Chief Wildlife Warden. UNESCO World Heritage Site (WHC): An international designation by UNESCO for sites of Outstanding Universal Value (OUV). Three types: Cultural (monuments, cities), Natural (ecosystems, geology), and Mixed (both). Inscription requires nomination by the host country to UNESCO’s World Heritage Committee. Does NOT provide any legal protection under Indian law — it is an international recognition that creates global attention, funding, and tourism. India has 44 WHC sites (7 Natural + 1 Mixed relevant to our topic). Biosphere Reserve (BR): A UNESCO designation under the MAB Programme — for areas that demonstrate how conservation and sustainable human development can coexist. Three-zone model (Core, Buffer, Transition). NOT a legal category under Indian WPA — it is an administrative/international designation overlaid on existing protected areas. India has 18 nationally designated BRs, 13 UNESCO-recognized. Can the same area be all three? YES, and frequently so! Examples: Sundarbans = NP (legal) + UNESCO WHC (international recognition) + Biosphere Reserve (MAB recognition) + Tiger Reserve + Ramsar Site — 5 simultaneous designations. Manas = NP + Tiger Reserve + UNESCO WHC + Biosphere Reserve + Ramsar = also 5 designations. Kaziranga = NP + Tiger Reserve + UNESCO WHC (but NOT a UNESCO BR — it has no MAB recognition separately). Nanda Devi: UNESCO WHC (1988) + UNESCO BR (2004) — WHC and BR are two separate UNESCO designations the same area can hold simultaneously. The key insight: all these designations come from DIFFERENT authorities (national government under WPA, UNESCO WHC Committee, UNESCO MAB programme) and confer DIFFERENT obligations and benefits. Having multiple designations = stronger legal + international conservation framework.
