BIOSPHERE RESERVES

DEFINITION
- Biosphere: Narrow zone where land, water and air interact to support life.
- Biosphere Reserves: Large areas of terrestrial/coastal ecosystems promoting conservation + sustainable use.

ORIGIN & GOVERNANCE
- Launched under UNESCO Man and Biosphere Programme (MAB), 1971.
- Internationally recognized but under sovereign control of national governments.
- Falls under IUCN Category V Protected Areas.

CRITERIA FOR DESIGNATION
- Pristine core area with high conservation value.
- Must cover a large biogeographic unit capable of sustaining trophic levels.
- Involvement of local communities and use of traditional knowledge.
- Potential to preserve tribal/rural sustainable lifestyles.

ZONATION PATTERN
1. CORE ZONE
- Strictly protected; no human interference.
- May contain endemic species & gene pools.
- Often overlaps with national parks/sanctuaries.
- Protected under Wildlife Protection Act, 1972.

2. BUFFER ZONE
- Surrounds core zone.
- Limited activities allowed: grazing, fishing, tourism, restoration.
- Research and education encouraged.

3. TRANSITION ZONE
- Outermost, inhabited zone.
- Settlements, agriculture, forest management allowed.
- Focus on sustainable development & cooperation.

MAN & BIOSPHERE PROGRAMME (MAB)
- Aim: Improve relationship between humans and environment.
- Provides scientific basis for sustainable use of resources.
- Governing Body: MAB International Coordinating Council (MAB-ICC).
- Advisory Bodies: Advisory Committee & International Support Group.

WORLD NETWORK OF BIOSPHERE RESERVES (WNBR)
- Global network of model conservation sites.
- Goals:
  • Harmonize people-nature relationship
  • Promote knowledge exchange
  • Reduce poverty & improve well-being
  • Support SDGs & Agenda 2030
- 686 reserves in 122 countries (including 20 transboundary sites).

Functions
- Study climate & ecological changes.
- Research ecosystem–society interactions.
- Improve human welfare in high-impact areas.
- Facilitate knowledge transfer & environmental education.

MAB & INDIA
Timeline:
- 1979: India formed MAB Committee; identified 13 ecosystems.
- 1986: Nilgiri became India’s first biosphere reserve under MAB.
- 2020: Panna BR added to UNESCO list.

15. Agasthyamala (TN–Kerala–Karnataka)
16. Nilgiri (TN–Kerala) – FIRST
17. Gulf of Mannar (Tamil Nadu)

RELATIONSHIP WITH OTHER PROTECTED AREAS
- BRs do NOT replace National Parks & Wildlife Sanctuaries.
- They enhance the PA network by focusing on:
  • Entire ecosystem conservation (not just flagship species)
  • Larger stakeholder and community participation
  • Global recognition under UNESCO

KEY DIFFERENCES (PA vs BR)
- NP/WS: Strict protection; minimal local involvement.
- BR: Community participation, sustainable development focus.
- BRs have international recognition via MAB.

INTERNATIONAL STATUS
- UNESCO designation aims to balance conservation & development.
- Requires national nomination and meeting MAB criteria.
