Recently, the Cold Desert Biosphere Reserve (CDBR) in Himachal Pradesh has been included in UNESCO’s World Network of Biosphere Reserves (WNBR), along with 25 other sites globally.¹

Notably, São Tomé and Príncipe (Central Africa) became the first nation to have its entire territory designated as a biosphere reserve.

Key Facts: Cold Desert Biosphere Reserve (CDBR)

• Location: Situated in the Trans-Himalayan region of Himachal Pradesh, the reserve spans the Spiti Wildlife Division and parts of the Lahaul Forest Division, with altitudes ranging from 3,300 to 6,600 meters.²

• Establishment: Designated as a biosphere reserve in 2009, it is India’s 16th BR and the first to represent a high-altitude cold desert ecosystem.³

• Landscape and Ecosystem: It integrates several protected areas, including Pin Valley National Park, Kibber Wildlife Sanctuary, and the Chandratal Wetland.⁴ Its landscape comprises windswept plateaus, glacial valleys, and alpine lakes, making it one of the coldest and driest ecosystems in the WNBR.⁵

• Biodiversity:

  • Flora: It is rich in unique plant life, including 14 endemic and 62 threatened species. Key medicinal plants like Salix spp. and hardy vegetation such as Himalayan birch (Betula utilis) are found here.

  • Fauna: It provides a critical habitat for rare and endangered species, including the Snow Leopard (as a flagship species), Himalayan Wolf, Tibetan Antelope, Himalayan Brown Bear, and the Himalayan Ibex.

Understanding Biosphere Reserves (BR)

• Definition: A Biosphere Reserve (BR) is an international designation by UNESCO under its Man and the Biosphere (MAB)⁷ Programme. They are recognized as significant natural and cultural landscapes that aim to reconcile biodiversity conservation with sustainable human development.⁸ This is a key method of in-situ conservation.

• Three Core Functions:

  1. Conservation: To protect ecosystems, species, and genetic diversity.⁹

  2. Sustainable Development: To foster economic and social growth that is culturally and ecologically sustainable.

  3. Logistic Support: To facilitate research, monitoring, education, and training related to conservation and sustainable development.¹⁰

• Zonal Structure: BRs are structured into three interrelated zones to fulfill their functions:¹¹

   

  • Core Area: A strictly protected zone for conserving biodiversity.¹² It is often an existing National Park or Wildlife Sanctuary.

     

     

  • Buffer Zone: Surrounds the core area. Activities compatible with sound ecological practices, such as research, education, and eco-tourism, are permitted.¹³

     

     

  • Transition Area: The outermost zone where communities practice socio-culturally and ecologically sustainable economic activities.

What is the World Network of Biosphere Reserves (WNBR)?

• About: The WNBR is a dynamic global network of sites of excellence operating under UNESCO’s MAB Programme.¹⁴

• Objective: It serves as a unique tool for international cooperation by promoting the exchange of knowledge, experiences, and best practices among biosphere reserves worldwide.¹⁵ It encourages North-South and South-South collaboration.

• Global Reach: The WNBR now includes 785 sites in 142 countries.¹⁶

Biosphere Reserves in India

• National Programme: India launched its Biosphere Reserve scheme in 1986, aligning with the landscape approach of the UNESCO MAB Programme.¹⁷

• Management and Funding: The scheme is centrally sponsored.

  • Funding Ratio: 90:10 for North Eastern and Himalayan states; 60:40 for other states.¹⁸

  • Management: The State Government prepares a Management Action Plan, which is approved and monitored by the Central MAB Committee.¹⁹

• Statistics: India has established 18 Biosphere Reserves.²⁰ With the inclusion of the Cold Desert BR, 13 of these are now part of UNESCO’s World Network of Biosphere Reserves.

Conclusion

The inclusion of the Cold Desert Biosphere Reserve in the WNBR is a significant recognition of India’s commitment to conserving its unique high-altitude ecosystems. It reinforces the success of the biosphere reserve model, which integrates biodiversity protection, cultural preservation, and sustainable livelihoods for local communities. This achievement strengthens India’s role within the global framework of the Man and the Biosphere (MAB) Programme, promoting a harmonious coexistence between humans and nature.²¹
