Effects of climatic variability on three fishing economies in high-latitude regions: Implications for fisheries policies

摘要

Research exploring how climatic variability impacts fishing economies in high-latitude regions was conducted in south-central Iceland and southwest Alaska during 2001-2004. Important differences were found regarding the economic impacts of climatic variations in the commercial economies in Iceland and Alaska, versus in the native subsistence economies in Alaska. In general, the commercially inclined economies in both regions seemed less resilient to ordinary climatic variability. Moreover, both of the commercial economies were importantly influenced by fluctuations in global fish markets that are prompted by climatic variations occurring in regions that are geographically very distant from them. A better understanding of how climatic variability affects fishing economies in high-latitude regions will help in the development of more sustainable fisheries policies for these regions, which may already be experiencing radical climatic and ecological change.
