The selection of study regions for the Frozen Commons project reflects our commitment to fostering trust and collaboration with local and Indigenous communities. Our longstanding partnerships and ongoing work in these areas have guided our decision to focus on Tsagaannuur and Bayanzürkh soums in Khövsgöl Province, Mongolia, and the rural and urban communities of McGrath and Nikolai in Alaska, USA.

These regions share common challenges, including limited transportation accessibility, economic reliance on natural resource extraction, and the significant impacts of climate change. Both areas are experiencing increasing climate variability: while some regions face extreme warm periods, others encounter contrasting snow patterns, such as fluctuations between thicker and thinner snow depths.

By applying a collaborative framework, the project seeks to deepen our understanding of these shared issues while honoring the unique environmental and cultural contexts of each location. Through cooperation with local and Indigenous stakeholders, we aim to uncover innovative approaches to adaptation, resilience, and sustainable futures for these frozen landscapes.

Mongolia  is rarely associated with the Arctic. However, Mongolia ranks as the fifth country globally in terms of permafrost extent while experiencing climate warming 2.7% faster than the rest of the world. Similarities with the Arctic are especially evident in the Khövsgöl aimag, home for reindeer, yak and cattle herding communities with similar environmental and cultural forms as well as the common issues faced by communities.

Bayanzürkh: A Heart of Mongolia’s Darkhad Depression

Bayanzürkh, meaning "rich heart" in Mongolian, is a district (soum) in Khövsgöl Province, covering an area of approximately 4,300 square kilometers (1,700 square miles). About 2,600 square kilometers (1,000 square miles) of this land is used as pasture. With a population of around 4,200, Bayanzürkh is home predominantly to the Darkhad people, known for their rich cultural heritage and traditional way of life.

Established in 1931 during the collectivization period of the socialist Mongolian People's Republic, Bayanzürkh's administrative center, Altraga, lies at the confluence of the Altraga and Beltes rivers, close to the Delgermörön River. Located 127 kilometers (79 miles) northwest of Mörön and 798 kilometers (496 miles) from Mongolia’s capital, Ulaanbaatar, Bayanzürkh is also the first settlement encountered when entering the picturesque Darkhad Depression.

The Darkhad Depression is named after its Indigenous people, who have preserved their traditional nomadic herding practices for generations. The Darkhad tend to herds of cattle, horses, sheep, goats, camels, and yaks, which provide essential resources such as milk, meat, clothing, and transportation. Additionally, they sell sheep and goat wool, yak and horse meat, pine nuts, and wild berries to supplement their livelihoods.

Darkhad families move their herds between pastures four to six times a year, adapting to the seasonal changes in grazing conditions. Their portable homes, known as gers or Mongolian yurts, are lightweight and easy to assemble, made of wood frames covered in felt or canvas. Aerial images often reveal circular traces of previous ger locations, which remain visible for years—a testament to their sustainable nomadic lifestyle.

While the community remains connected to others by a bridge, local concerns focus more on the degradation of shared pastures, a pressing issue for the Darkhad who depend so intimately on the land for their way of life.

Tsagaannuur: Home of Mongolia’s Reindeer-Herding Dukha People

Tsagaannuur, meaning “white lake” in Mongolian, is a district (soum) in Khövsgöl Province, covering an area of 5,410 square kilometers (2,088 square miles). As of 2000, the population of Tsagaannuur was 1,317, primarily made up of the Darkhad people, with 269 identifying as Dukha, also known as Tsaatan or “reindeer-herding people.” The soum’s administrative center, Gurvansaikhan, is situated on the shore of Dood Tsagaan Lake.

Tsagaannuur was established in 1985 after being split off from the neighboring Renchinlkhümbe soum. It was originally part of a Soviet-era initiative to create fish processing infrastructure, which disrupted the traditional migration routes of the Dukha people. Families were forced to settle in the village, where adults worked in factories, and children were enrolled in boarding schools. After Mongolia’s peaceful democratic revolution in the 1990s, some Dukha families returned to their traditional reindeer herding practices, though many continue to migrate closer to the village during the school year for their children’s education.

The Dukha, or Tsaatan, are renowned for their deep connection to reindeer, which serve as more than just a source of food and transportation—they hold profound spiritual and emotional significance. These bonds are central to Dukha's identity and traditions. The Dukha primarily inhabit the Eastern and Western Taiga, remote boreal forests where reindeer provide milk, meat, and hides, as well as assistance with transportation.

The Dukha’s traditional dwellings, known as ortz, are cone-shaped tents similar to Native American tipis. In summer, ortz are covered with birch bark, while in winter they are insulated with reindeer hides. Today, 96% of Tsagaannuur soum’s territory is protected land, governed by local and national regulations that affect land use.

Tourism has become a vital source of income for the Dukha. Many families offer visitors handmade souvenirs, accommodations in their ortz, meals, and guide services. However, the Dukha face numerous challenges, including the rapid decline of their population—from 296 in 2000 to just 189 in 2021—and the impacts of climate change.

Global warming has severely disrupted Dukha’s nomadic lifestyle, with snow and ice that traditionally remained frozen throughout the summer now melting in Mongolia’s remote taiga. These changes threaten both their way of life and their unique cultural heritage.
