© contributed Workshop on Ecosystem-Based Management Concludes: Managing Arctic marine ecosystems requires international, multidisciplinary, and cross-sectoral cooperation December 17, 2024 To promote healthy and productive oceans and enhance sustainability of Arctic Ocean industries, the Norwegian Chairship of the Arctic Council (2023-2025) has focused on integrated ocean management. One important tool for regulating human activities to avoid critical impacts on the ecosystem is the Ecosystem Approach to Management. As part of its Chairship Program, Norway hosted the third International Conference on Ecosystem Approach to Management in Arctic Large Marine Ecosystems earlier this year. To follow up on the conference’s important outcomes, the Norwegian Chairship and international partners recently convened a workshop in Copenhagen, Denmark, to identify effective ways to promote international collaboration for producing, accessing, synthesizing, and sharing knowledge of the Central Arctic Ocean among organizations and Working Groups involved in the production of relevant knowledge, and those using this knowledge as a basis for advice and management decisions.Arctic warming, retreating sea ice, and increased human activity are causing unprecedented changes with far-reaching consequences for Arctic marine ecosystems and the communities that rely on them. Ecosystem-based management – or ecosystem approach to management (EA) – is an established practice that offers approaches to address these challenges. The third International Conference on Ecosystem Approach to Management in Arctic Large Marine Ecosystems (LMEs), held in April 2024 in Tromsø, Norway, highlighted the importance of effective cooperation to ensure a safe and sustainable future for the Arctic. The Arctic Council and other international bodies view the ecosystem approach to LMEs as an important ongoing and future step to achieve this.

To follow up on these outcomes and prepare for continued work under the upcoming Arctic Council Chairship of Kingdom of Denmark commencing in May 2025, a workshop was held in Copenhagen, Denmark, from 10-12 December 2024. The workshop brought together 28 in-person and 11 online representatives from organizations representing Arctic governance, science and Indigenous Peoples to discuss and identify effective ways to promote international collaboration that can produce, share, access, synthesize, and make evidence-based advice relevant to EA in Arctic LMEs. During three intensive workshop days, participants discussed the information needed by organizations with mandates to provide management advice or make management decisions. They explored who can produce and deliver this information, and how the collection, assessment, synthesis and sharing of relevant information can be made more effective across the involved organizations and Working Groups.
