The inclusion of the Cold Desert Biosphere Reserve (CDBR) in Himachal Pradesh into UNESCO’s World Network of Biosphere Reserves (WNBR) marks a milestone in India’s biodiversity conservation journey. Spanning 7,770 sq km across Lahaul-Spiti district, this cold desert ecosystem is among the driest and harshest environments on Earth, yet home to unique flora, fauna, and resilient human communities.

Constitutional Provisions for Biodiversity Protection in India

India’s commitment to biodiversity conservation is backed by strong constitutional safeguards:

• Article 48A (Directive Principles of State Policy): The State shall endeavour to protect and improve the environment and to safeguard forests and wildlife.
• Article 51A(g) (Fundamental Duties): It is the duty of every citizen to protect and improve the natural environment including forests, lakes, rivers, and wildlife, and to have compassion for living creatures.
• Schedule VII (Union & Concurrent Lists): Provides legislative powers for Parliament and State Legislatures to enact laws for forests, wildlife protection, and biodiversity management.

What is a Biosphere Reserve?

A biosphere reserve is a designated area that aims to balance biodiversity conservation with sustainable use of natural resources, while also involving local communities.

The Three Zones of a Biosphere Reserve:

1. Core Zone: Strictly protected ecosystem for conservation of biodiversity, monitoring, and research.
2. Buffer Zone: Surrounds the core, permits limited human activity such as eco-tourism, research, and education.
3. Transition Zone: Outermost area where communities live and sustainable resource use is promoted.

Cold Desert Biosphere Reserve (CDBR), Himachal Pradesh

• Location: Trans-Himalayan region, covering Spiti Wildlife Division & adjoining Lahaul Forest Division.
• Altitude Range: 3,300 m to 6,600 m.
• Zones: Core (2,665 sq km), Buffer (3,977 sq km), Transition (1,128 sq km).
• Protected Areas Integrated:
  • Pin Valley National Park
  • Kibber Wildlife Sanctuary
  • Chandratal Wetland
  • Sarchu Plains

Biodiversity Highlights:

• Flora: 655 herbs, 41 shrubs, 17 tree species, including 47 medicinal plants linked to the Sowa Rigpa/Amchi system of Tibetan medicine.
• Fauna: 17 mammal & 119 bird species, including:
  • Snow Leopard (flagship species)
  • Himalayan ibex
  • Himalayan wolf
  • Blue sheep (primary prey base, >800 in Spiti valley)

Socio-Cultural Significance:

• Population: ~12,000 inhabitants in scattered villages.
• Livelihoods: Pastoralism, yak & goat herding, barley & pea farming.
• Cultural Fabric: Deeply connected with Buddhist monasteries, community councils, and traditional Tibetan medicine.

World Network of Biosphere Reserves (WNBR)

• Established under UNESCO’s Man and the Biosphere (MAB) Programme.
• A dynamic and participatory network of areas recognized for their ecological and cultural value.
• As of 2024: 785 sites in 142 countries.
• With CDBR’s inclusion, India now has 13 biosphere reserves in the WNBR.

Biosphere Reserves in India under WNBR

India has 18 notified biosphere reserves, of which 13 are part of WNBR:

1. Nilgiri
2. Gulf of Mannar
3. Sundarbans
4. Nanda Devi
5. Nokrek
6. Pachmarhi
7. Similipal
8. Achanakmar–Amarkantak
9. Great Nicobar
10. Agasthyamalai
11. Khangchendzonga
12. Panna
13. Cold Desert (newly added)

Ecological and Socio-Cultural Significance of CDBR’s Inclusion

• Ecological: Enhances global recognition of fragile Trans-Himalayan ecosystems; strengthens conservation of snow leopards, medicinal plants, and alpine habitats.
• Socio-Cultural: Highlights traditional Tibetan practices, Buddhist monastic heritage, and community-led sustainable resource use.
• Tourism & Climate Change: Draws attention to pressures of mass tourism and climate vulnerabilities in high-altitude ecosystems.

The Man and the Biosphere (MAB) Programme

• Launched: 1971 by UNESCO.
• Objective: Promote conservation of biodiversity, sustainable development, and research on human-environment interaction.
• Unique Feature: Integration of local communities into conservation planning, unlike strict nature reserves.

Flagship Species in Conservation Planning

• A flagship species is a charismatic or ecologically significant species chosen to represent conservation goals in a region.
• Example: The Snow Leopard in CDBR serves as a flagship species—its survival ensures the protection of entire ecosystems and prey species such as blue sheep.

Conclusion

The inclusion of Himachal Pradesh’s Cold Desert Biosphere Reserve in the UNESCO WNBR list is not just a recognition of its unique ecology but also a reminder of the delicate balance between conservation and community livelihoods. As India strengthens its global standing with 13 biosphere reserves in the WNBR, the emphasis must remain on safeguarding biodiversity, promoting sustainable tourism, and empowering local communities to steward these fragile ecosystems.
