Cold Desert Biosphere Reserve (CDBR)

The Cold Desert Biosphere Reserve (CDBR), located in Himachal Pradesh, India, has recently earned global recognition as it has been included in the World Network of Biosphere Reserves (WNBR) by UNESCO, alongside 25 other biosphere reserves from different countries.

Key Facts about the Cold Desert Biosphere Reserve

  1. Location:

    • Region: Situated in the Trans-Himalayan region, the reserve spans the Spiti Wildlife Division and adjacent areas of the Lahaul Forest Division, including the Baralacha Pass, Bharatpur, and Sarchu. The altitudes range from 3,300 to 6,600 meters.

    • Established: The CDBR was declared in 2009 as India's 16th biosphere reserve and the first high-altitude cold desert biosphere reserve in the country.

  2. Landscape:

    • The landscape integrates several protected areas, including Pin Valley National Park, Kibber Wildlife Sanctuary, and the Chandratal Wetland.

    • Characterized by windswept plateaus, glacial valleys, alpine lakes, and high-altitude desert, it is one of the coldest and driest ecosystems in the world, making it a unique biosphere reserve.

  3. Floral Diversity:

    • The reserve is home to 14 endemic plant species, 68 native species, and 62 threatened plant species, including key medicinal plants such as Salix spp., Betula utilis, and others.

    • It also supports alpine grasses, medicinal herbs, and rare stands of species like Willow-leaved Sea-buckthorn, Himalayan Birch, and Persian Juniper.

  4. Faunal Diversity:

    • The CDBR is home to rare and endangered species, such as:

      • Snow Leopard

      • Himalayan Wolf

      • Tibetan Antelope

      • Himalayan Brown Bear

      • Himalayan Griffon

      • Himalayan Ibex

      • Bearded Vulture

      • Red Fox

      • Tibetan Gazelle

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

  • Definition: The World Network of Biosphere Reserves (WNBR) is a dynamic network of protected areas across the globe that serves as a platform for international cooperation in biodiversity conservation, research, and sustainable development.

  • UNESCO Affiliation: The WNBR operates under the UNESCO’s Man and the Biosphere (MAB) Programme, a global initiative that promotes eco-friendly sustainable development.

  • Global Coverage: The network currently includes 785 sites across 142 countries, covering over 1 million square kilometers of natural areas protected since 2018—equivalent in size to Bolivia.

Role and Function of Biosphere Reserves

A Biosphere Reserve (BR) is a designation given by UNESCO to areas that aim to balance conservation of biodiversity with sustainable economic development. These reserves act as living laboratories for research and education about the environment and sustainable human activities.

  • Three Key Functions of a Biosphere Reserve:

    1. Conservation: Protecting biodiversity and cultural heritage.

    2. Economic Development: Promoting environmentally and socially sustainable growth.

    3. Logistic Support: Facilitating research, education, and capacity building.

  • Structure of Biosphere Reserves:

    1. Core Areas: Strictly protected for conservation of ecosystems and species.

    2. Buffer Zones: Surround the core areas and are used for eco-friendly activities such as research and education.

    3. Transition Zones: Areas where communities engage in sustainable practices that benefit both people and the environment.

Criteria for Designating a Biosphere Reserve:

  • A protected and minimally disturbed core area with significant conservation value.

  • A focus on preserving traditional tribal or rural lifestyles and incorporating local community knowledge in biodiversity conservation.

  • Ensuring large enough areas for sustainable populations and ecosystems across various trophic levels (e.g., plants, herbivores, predators).

Biosphere Reserves in India

  • India launched the Biosphere Reserve scheme in 1986, guided by UNESCO’s MAB Programme.

  • The country has 18 Biosphere Reserves, with 13 of them listed under UNESCO’s World Network of Biosphere Reserves (WNBR).

Funding and Management:

  • The Indian government provides financial assistance to Biosphere Reserves in a 90:10 ratio for the North-Eastern and Himalayan States, and 60:40 for other states for their maintenance and development.

  • Each Biosphere Reserve has a Management Action Plan, which is prepared by the State Government and approved by the Central MAB Committee.

Conclusion:

The inclusion of the Cold Desert Biosphere Reserve (CDBR) in the World Network of Biosphere Reserves further cements its role in global conservation. The reserve plays an essential role in the preservation of rare species, especially in high-altitude ecosystems like the Trans-Himalayan region, which are increasingly threatened by climate change.
