Nomadic Yak Herders of Bhutan

The nomadic and semi-nomadic yak herders of Bhutan, collectively referred to as Brokpa (literally "herders" or "highlanders" in Dzongkha), are among the most culturally distinctive communities in the Himalayan region. These highland pastoral peoples have practised transhumant yak herding for centuries across Bhutan's northern alpine zones, moving their herds seasonally between high-altitude summer pastures and lower winter camps. The major yak-herding communities are found in Merak and Sakteng in Trashigang Dzongkhag, Laya in Gasa Dzongkhag, and highland areas of Bumthang, Haa, and Paro districts. The ethnic groups involved in yak raising include the Brokpas and Dakpas of central and eastern Bhutan, the Bjops of western Bhutan, and the Lakhaps of the west-central region.^[1]

Yak herding represents one of the oldest forms of human adaptation to the harsh conditions of the high Himalayas. The yak (Bos grunniens) is superbly adapted to high altitudes, capable of thriving at elevations above 3,000 metres where conventional cattle cannot survive. For Bhutan's highland communities, the yak has historically been the foundation of economic life, providing milk, butter, cheese, meat, wool, hair for weaving, hides, and dung for fuel. The animals also serve as pack animals on the high mountain trails that connect Bhutan's isolated northern valleys. Despite their cultural and economic significance, yak-herding communities are today among the most marginalised in Bhutan, facing existential pressures from climate change, rural-urban migration, declining yak populations, and limited access to modern services.^[2]

Transhumant Pastoralism

The yak-herding communities of Bhutan practise transhumance — the seasonal movement of livestock between fixed summer and winter pastures at different altitudes. This system, known locally as drukor, is finely calibrated to the ecological rhythms of the Himalayan highlands. During the warmer months (roughly May to September), herders drive their yaks to high-altitude alpine meadows above the tree line, where lush grasses provide rich grazing. As temperatures drop with the approach of winter, herders descend with their animals to lower valleys, where they shelter in semi-permanent camps and supplement their subsistence through barter and trade with agricultural communities at lower elevations.^[3]

The barter economy has historically been central to the Brokpa way of life. Around the time of the first frost, herders descend to villages to trade yak products — butter, dried cheese (chugo), meat, and wool — for items they cannot produce themselves, including rice, salt, chillies, and kerosene. This reciprocal exchange between highland and lowland communities has sustained a web of economic and social relationships across Bhutan's vertical landscape for generations.

The Brokpa of Merak and Sakteng

The best-known yak-herding community in Bhutan is the Brokpa of Merak and Sakteng, two remote villages in the far east of the country within Trashigang Dzongkhag. The Brokpa are ethnically distinct from other Bhutanese, tracing their origins to the Tshoona region of Tibet, from which they are believed to have migrated several centuries ago. They speak Brokkat, a language distinct from Dzongkha and Sharchopkha. The Brokpa are immediately recognisable by their distinctive headgear — the tsipee cham, a black felt hat made from yak hair, with a flat crown and dangling twisted tufts that serve to channel rainwater away from the face. Their clothing, woven from yak wool, and their semi-nomadic way of life set them apart from the settled agricultural communities that predominate in most of Bhutan.^[4]

Merak and Sakteng sit within the Sakteng Wildlife Sanctuary, one of the few protected areas in the world established partly to protect the habitat of an animal whose existence has not been scientifically confirmed — the migoi (yeti) of Bhutanese folklore. The sanctuary also protects the alpine meadows and temperate forests upon which the Brokpa's transhumant economy depends.

Highland Communities of Western Bhutan

In western Bhutan, the Layap people of Laya in Gasa Dzongkhag are another prominent yak-herding community. Living at elevations of approximately 3,800 metres, the Layap are known for their distinctive conical bamboo hats and their reliance on yak herding and the collection of cordyceps sinensis (yartsa gunbu), a highly valued medicinal caterpillar fungus. The sale of cordyceps has in recent decades provided a significant supplementary income for highland herders, though the trade is tightly regulated by the government and its long-term sustainability is uncertain. Further south, in the highland valleys of Haa, Paro, and Bumthang, smaller communities of yak herders maintain the pastoral traditions of their forebears, though in many cases on a diminishing scale.^[5]

Climate Change and Environmental Pressures

Climate change poses a severe and growing threat to Bhutan's yak-herding communities. Research conducted with highland herders has documented perceptions of warming temperatures, longer vegetation growing periods, increased rainfall variability, decreased water availability in some areas, ascending snow lines, and more frequent flash floods and landslides. Particularly concerning is the encroachment of rhododendron and other woody shrubs into alpine meadows, which has reduced the size and quality of grassland pastures available for yak grazing. Herders in northern Bhutan have reported these changes with increasing alarm, noting that conditions they relied upon for generations are shifting in unpredictable ways.^[6]

The United Nations Development Programme (UNDP) has supported efforts to enhance the resilience of highland communities in Gasa (Laya), Trashigang (Merak and Sakteng), and other areas, introducing initiatives to combat climate-induced challenges such as pasture degradation, water scarcity, and the increased incidence of livestock diseases in warming conditions.^[7]

Declining Yak Populations and Youth Migration

Bhutan's yak-herding communities face a convergence of socioeconomic pressures that threaten the viability of the pastoral way of life. Research on the Brokpa of Merak and Sakteng has documented a significant decline in the number of households engaged in yak herding — from a time when most households owned yaks to the present, when fewer than 20 per cent of households do so. The decline is driven by multiple factors: a shortage of labour resulting from young people leaving villages for education and employment in urban areas; overgrazing and the shrinking of rangelands; low productivity of yaks resulting from inbreeding; disease outbreaks; and a shrinking market economy for traditional yak products.^[8]

The pull of modernisation and urban life is particularly acute among younger Brokpa, who increasingly seek formal education and salaried employment rather than the physically demanding and economically uncertain life of transhumant herding. This generational shift threatens the continuity of traditional ecological knowledge and pastoral skills that have been passed down orally for centuries.

Government and Development Responses

The Royal Government of Bhutan and international development partners have recognised the precarious situation of highland herding communities and have implemented programmes aimed at improving their livelihoods and resilience. Initiatives include the provision of veterinary services, the introduction of improved yak breeds to address inbreeding, the development of value-added yak products for commercial markets, and the construction of basic infrastructure (trails, bridges, and solar power installations) to reduce the isolation of highland communities. The Gross National Happiness framework, with its emphasis on equitable development and cultural preservation, provides a policy rationale for investing in the welfare of these small but culturally significant communities.^[9]

Cultural Significance

Beyond their economic role, Bhutan's yak-herding communities are custodians of unique cultural traditions, languages, oral histories, and ecological knowledge. The Brokpa of Merak and Sakteng, the Layap of Laya, and other highland groups represent a way of life that predates the formation of the modern Bhutanese state and embodies a form of human adaptation to extreme environments that is rapidly disappearing across the Himalayan region. Their preservation is not only a matter of livelihoods but of cultural diversity and heritage.
