Svalbard Global Seed Vault in the context of Crop Trust

Longyearbyen (Urban East Norwegian: [ˈlɔ̀ŋjɛrˌbyːən], locally [ˈlɔ̀ŋjɑrˌbyːən], "Longyear Town") is the world's northernmost settlement with a population greater than 1,000, and the capital and the largest inhabited area of Svalbard. It stretches along the foot of the left bank of the Longyear Valley and on the shore of Adventfjorden, the short estuary leading into Isfjorden on the west coast of Spitsbergen, the island's broadest inlet. As of 2002, Longyearbyen Community Council is an official Norwegian municipality. It is the seat of the Governor of Svalbard. As of 2024, the town's mayor is Leif Terje Aunevik.

Known as Longyear City until 1926, the town was established by and named after American John Munro Longyear, whose Arctic Coal Company started coal-mining there in 1906. Store Norske Spitsbergen Kulkompani (SNSK) took over the mining operations in 1916, and still conducts mining. The German Kriegsmarine almost completely destroyed the town on 8 September 1943, but rebuilding took place after the Second World War. Historically, Longyearbyen was a company town, but most mining operations moved to Sveagruva during the 1990s, and production ceased in 2017 due to immense financial losses suffered by SNSK since 2014 due to market conditions. Meanwhile, the town has seen a large increase in tourism and research. This includes the arrival of institutions such as the University Centre in Svalbard, the Svalbard Global Seed Vault and Svalbard Satellite Station. Svalbard Airport, Svalbard Church and the Svalbardbutikken department store serve the community.

Ex situ conservation (lit. 'off-site conservation') is the process of protecting an endangered species, variety, or breed of plant or animal outside its natural habitat. For example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, such as a zoological park or wildlife sanctuary. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality.

Ex situ management can occur within or outside a species' natural geographic range. Individuals maintained ex situ exist outside an ecological niche. This means that they are not under the same selection pressures as wild populations, and they may undergo artificial selection if maintained ex situ for multiple generations.
