In September 2025, the trans-Himalayan landscape of Lahaul-Spiti in Himachal Pradesh was officially included in UNESCO’s World Network of Biosphere Reserves (WNBR) under the Man and the Biosphere (MAB) Programme. It became India’s first high-altitude Cold Desert Biosphere Reserve and India’s 13th UNESCO Biosphere Reserve. The recognition was announced during the 37th MAB-ICC Meeting held in Hangzhou, China.
The Cold Desert Biosphere Reserve spreads across nearly 7,770 square kilometres in the trans-Himalayan region. It covers the entire Spiti Wildlife Division and adjoining areas of the Lahaul Forest Division.The reserve includes major ecological regions such as:
The biosphere reserve lies at elevations ranging from nearly 3,300 metres to 6,600 metres above sea level. The landscape consists of:
The region falls within the Indian Himalayan Biogeographic Province and is considered among the coldest and driest ecosystems in UNESCO’s biosphere reserve network.
The reserve follows the standard UNESCO biosphere zonation model.
| Zone | Area |
|---|---|
| Core Zone | 2,665 sq km |
| Buffer Zone | 3,977 sq km |
| Transition Zone | 1,128 sq km |
The zonation supports both biodiversity conservation and sustainable livelihood activities.
The recognition came under UNESCO’s Man and the Biosphere (MAB) Programme, an intergovernmental scientific initiative that aims to improve the relationship between humans and nature.The programme promotes:
The MAB Programme integrates natural sciences and social sciences to create environmentally sustainable and culturally appropriate development models.The inclusion of Spiti in the WNBR is part of UNESCO’s broader effort to promote innovation, sustainability, and ecological stewardship.
The reserve represents a unique cold desert ecosystem shaped by:
The region supports a rich diversity of flora and fauna despite severe climatic conditions.
The reserve contains:
Another assessment mentions:
The area also contains numerous medicinal plants associated with the traditional Sowa Rigpa (Amchi) healing system.
The Cold Desert Biosphere Reserve is home to several high-altitude Himalayan species.
The region contains more than 800 Blue Sheep, creating a strong prey base for large carnivores such as the snow leopard.
The reserve reportedly supports:
The Snow Leopard acts as the flagship species of the biosphere reserve. Its presence indicates ecological stability in the high-altitude Himalayan ecosystem.The conservation of snow leopard habitats also helps protect:
Pin Valley and areas around Kibber and Langza are important habitats for snow leopards.
The trans-Himalayan region is not an uninhabited wilderness. Around 12,000 inhabitants live in scattered settlements across the biosphere reserve.The local population practices:
Community institutions and Buddhist monastic traditions regulate the use of fragile alpine resources.Ancient gompas (Buddhist monasteries) and stone villages form an important part of the cultural landscape.
UNESCO recognition is expected to encourage:
The region is suitable for:
The biosphere status also increases emphasis on regulated tourism in ecologically sensitive zones.
Despite international recognition, the region remains environmentally fragile.Major concerns include:
Peak winter conditions and heavy snowfall further increase ecological vulnerability.
The inclusion of Spiti in UNESCO’s WNBR has multiple implications.
The recognition places India’s trans-Himalayan ecosystems prominently on the global conservation map.
With the inclusion of the Cold Desert Biosphere Reserve, India now has 13 UNESCO Biosphere Reserves in the World Network of Biosphere Reserves.The Cold Desert Biosphere Reserve is:
