Changing uses and values of marine
ecosystem services in the Norwegian Arctic
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 non-
monetary values
3) Demonstrate valuation methods in region-
specific case studies
4) Analyse how value information can be used
for trade-offs in policy and decision making
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 sea-
lice infestation of wild salmon may
increase?
• Sea-bed impacts?
• Effects on wild fisheries?
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
Mining (https://www.tekes.fi/globalassets/programmes-and-
services/green-mining/pdac-2015/14.-oystein-rushfeldt----nussir-asa.pdf )
• 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
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.
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
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)
