Spanning 7,770 square kilometers across the trans-Himalayan region at altitudes of 3,300 to 6,600 meters, the reserve includes Pin Valley National Park, Chandratal, Sarchu, and Kibber Wildlife Sanctuary.

UNESCO has added India’s Cold Desert Biosphere Reserve to its World Network of Biosphere Reserves (WNBR), marking the country’s first high-altitude cold desert reserve and its 13th UNESCO biosphere site, the organization announced at the 5th World Congress of Biosphere Reserves in Hangzhou, China.

Spanning 7,770 square kilometers across the trans-Himalayan region at altitudes of 3,300 to 6,600 meters, the reserve includes Pin Valley National Park, Chandratal, Sarchu, and Kibber Wildlife Sanctuary. It features glacial valleys, alpine lakes, and one of the world’s coldest, driest ecosystems, hosting 732 vascular plant species, including 30 endemics, and iconic fauna like the snow leopard, Himalayan ibex, and golden eagle.

Home to 12,000 people in scattered villages, the region sustains traditional practices such as yak herding, barley farming, and Tibetan herbal medicine, guided by Buddhist monastic traditions and community resource management.

“This designation highlights India’s commitment to balancing conservation with sustainable development in fragile, culturally rich ecosystems,” said Tim Curtis, Director of UNESCO’s Regional Office for South Asia. “Biosphere reserves are learning hubs for fostering harmony between people and nature.”

Announced during the 50th anniversary of UNESCO’s Man and the Biosphere (MAB) Programme, the Cold Desert joins 26 new sites in the WNBR, now totaling 785 globally. The MAB promotes interdisciplinary approaches to biodiversity conservation, sustainable economic development, and research, with biosphere reserves serving as models for local solutions to global challenges.

The 5th World Congress, attended by over 3,000 participants from more than 100 countries, marks the first time the event has been held in Asia, underscoring the MAB’s growing global inclusivity.
