10 Objectives and research questions The project recognizes that global changes in climate change and human activities may affect utilization of marine ecosystem services (ES) in the northernmost part of Norway. By providing reliable monetary and non-monetary values of marine ES in an amended cost-benefit analysis (CBA) framework and as input in bio-economic models the project aims to deliver improved tools for decision-making on trade-offs between different uses of marine ES spatially and across stakeholders. 1) Set up model to show private and commercial activities dependence on ES 2) To amend standard CBA framework and bio-economic models to better include nonmonetary values 3) Demonstrate valuation methods in regionspecific case studies 4) Analyse how value information can be used for trade-offs in policy and decision making

12 Aquaculture expansion in Arctic Norway Five-fold increase, super-proportional share in Arctic Norway Climate change implies higher sea temperature in the north With more intensive fish farming the sealice infestation of wild salmon may increase? Sea-bed impacts? Effects on wild fisheries?

13 Valuation workshops taking into account uncertainties Parallel workshops; one were we present info about the aquaculture expansion and possible environmental effects as relatively certain and one where the same information is presented, but as uncertain The participants are given exactly the same survey-questions, only info differ Does uncertainties regarding the valuation scenarios affect peoples responses? If yes; how does it change their responses? Meridian.org

14 Mining ( ) Sea tailings deposits, Repparfjord = national salmon fjord Electronic survey in Finmark county In the survey people are asked to trade-off between mining and new jobs and environmental aspects (ecosystem services) Non-monetary assessment collected through in-depth interviews with stakeholders in and around Kvalsund municipality

15 Marine fishing tourism The coastal cod and it s diverse uses; traditional fisheries, tourist fishers, and recreational fishing for locals But; stocks have been declining for years, and the British SEAFISH has rated it as follows: Norwegian coastal cod has been scored a high risk. Although the spawning stock biomass appears stable, it is close to the lowest observed level. Recruitment has also been at a low level in recent years.

16 Marine fishing tourism Internet-based survey asking people to assess the three different uses of the coastal cod. Results from the survey will be used as input in bio-economic modelling PhD-student will work on this case This case-study will also be related to the research project Coast benefits This case study will be a comparative study together with a Portuguese study

17 Sea transport and oil spill risk Huge quantities of crude oil and refined petroleum products are transported by ship between production sites, refineries and points of consumption. Oil shipments account for about 30% of global maritime trade. Based on existing work by Menon on WTP for increased oil-spill security Comparative study between Norway (Lofoten islands) and Portugal (Sines, one of Europe s largest oil refineries)
