Polar regions are naturally dynamic environments. Ecosystems in polar regions, and the people who rely on them, have adapted to natural variability and dynamic nature of polar environments. Fish populations in polar regions are known to exhibit cycles of productivity, and shift their distribution across hundreds of kilometres in response to changes in winter sea ice cover and concomitant summer ocean conditions. Management of the productive fisheries in polar regions is also designed to allow for these changes, using adaptive and ecosystem-based approaches that buffer populations from overexploitation and also stabilise fisheries, livelihoods and food resources. Indigenous Peoples diversify their subsistence harvest across species and resources and, therefore, similarly stabilise food and nutritional security.
