With the official addition of Himachal Pradesh's Cold Desert Biosphere Reserve to UNESCO's World Network of Biosphere Reserves, India has become the 13th country to get this status. The reserve, which is roughly 7,770 square kilometres in size and is situated in the trans-Himalayan region of Lahaul and Spiti, has difficult high-altitude terrain, uncommon fauna, delicate ecosystems, and human populations that have long coexisted with this hard climate.
The decision to include the Cold Desert Biosphere Reserve in the World Network of Biosphere Reserves (WNBR) was made at UNESCO’s 37th session of the International Coordinating Council of the Man and the Biosphere (MAB) programme. With this addition, India now has 13 biosphere reserves recognised globally. UNESCO also announced 26 new biosphere reserves across 21 countries during the same period.
Officials have described the Cold Desert Reserve as India’s first high-altitude cold desert biosphere, reflecting its status as one of the coldest and driest ecosystems in the WNBR.
The Cold Desert Biosphere Reserve is spread over roughly 7,770 square kilometres in the Lahaul and Spiti district of Himachal Pradesh. Its altitudes range from about 3,300 to 6,600 metres. The topography includes windswept plateaus, glacial valleys, alpine lakes, high deserts and rugged terrain.
The reserve encompasses key protected areas such as Pin Valley National Park, Kibber Wildlife Sanctuary, Chandratal Wetland, and the Sarchu plains. Internally, the biosphere is divided into three functional zones — core, buffer and transition — intended to balance strict conservation, sustainable use and community engagement.
Despite its severe conditions, the Cold Desert region is home to a variety of life. There are hundreds of plant species found there, including endemics and medicinal herbs. There are 119 bird species and 17 animal species in the fauna, with the snow leopard serving as a flagship species. Blue sheep, Himalayan wolves, and Himalayan ibex are among the other creatures.
The reserve's dispersed high-altitude communities are home to about 12,000 inhabitants. The traditional livelihoods of these populations include pastoral activities like herding goats and yaks, growing barley and peas, using herbal remedies like Tibetan amchi or Sowa Rigpa, and managing delicate natural resources through traditional local councils.
It is anticipated that the UNESCO inscription will support efforts to build climate resilience in mountainous ecosystems, encourage responsible ecotourism, and deepen research collaborations. State forest officials have praised the action, stating that it puts the area on the map of global conservation.
The recognition, according to Union Environment Minister Bhupender Yadav, demonstrates India's dedication to sustainable development and biodiversity preservation. Additionally, he stated that the decision was made in conjunction with other UNESCO initiatives, such the expansion of India's Ramsar wetland sites.
Regardless of the status and opportunity that come with recognition, the Cold Desert region is under a lot of pressure. Its delicate alpine ecosystem is susceptible to the effects of climate change, including temperature extremes, altered precipitation patterns, and glacial retreat. Another issue is the pressure from tourists, particularly in delicate areas. It would be crucial to strike a balance between community livelihoods and protection. Local involvement and efficient governance will be crucial since the biosphere model aims to integrate conservation and human activity.
