• Balancing conservation goals and ecotourism development in coastal wetland management in Sri Lanka: A choice experiment 

      Dushani, Salpage Nesha; Aanesen, Margrethe; Vondolia, Godwin K (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-15)
      Understanding the tradeoff between tourism development and environmental conservation is essential for the sustainable management of ecotourism. Accordingly, we conducted a choice experiment (CE) using valuation workshops to estimate the preferences of foreign tourists for ecotourism development and biodiversity conservation in Rekawa coastal wetland in Southern Sri Lanka. Transforming preferences ...
    • Cost-benefit analysis of aquaculture expansion in Arctic Norway 

      Aanesen, Margrethe; Mikkelsen, Eirik Inge (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)
      According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up a ...
    • Demographic and economic disparities among Arctic regions 

      Schmidt, Jennifer Irene; Aanesen, Margrethe; Klokov, Konstantin; Kruschov, Sergei; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-20)
      We use demographic and economic indicators to analyze spatial differences and temporal trends across 18 regions surrounding the Arctic Ocean. Multifactor and cluster analysis were used on 10 indicators reflecting income, employment and demography from 1995 to 2008. The main difference is between regions with high population densities, low natural growth rate, and low unemployment (Russia, Norway ...
    • Do we choose differently after a discussion? Results from a deliberative valuation study in Ireland 

      Aanesen, Margrethe; Armstrong, Claire W.; Van Rensburg, Tom M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      A criticism against individual-based stated preference surveys is that people seldom make choices in social isolation. An approach used in response to this is deliberative valuation. We conduct a series of valuation workshops including a choice experiment. This involves providing respondents with information and opportunity to discuss. They made their choices individually both before and after the ...
    • Global ecological, social and economic impacts of marine plastic 

      Beaumont, Nicola J; Aanesen, Margrethe; Austen, Melanie C.; Borger, Tobias; Clark, James R; Cole, Matthew; Hooper, Tara; Lindeque, Penelope K.; Pascoe, Christine; Wyles, Kayleigh J (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-27)
      This research takes a holistic approach to considering the consequences of marine plastic pollution. A semi-systematic literature review of 1191 data points provides the basis to determine the global ecological, social and economic impacts. An ecosystem impact analysis demonstrates that there is global evidence of impact with medium to high frequency on all subjects, with a medium to high degree of ...
    • Informing management strategies for a reserve: Results from a discrete choice experiment survey 

      Bui, Bich Xuan; Sandorf, Erlend Dancke; Aanesen, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-18)
      It is well-known that operating within the boundaries of a national park provides commercial actors with the opportunity to charge a price premium, though this has to a lesser degree been demonstrated for marine protected areas. We estimate national tourists' willingness-to-pay a price premium for boat trips in the Nha Trang Bay Marine Protected Are, Vietnam, using a discrete choice experiment. Our ...
    • Is the Sri Lankan ecotourism industry threatened by climate change? A case study of Rekawa coastal wetland using contingent visitation approach 

      Salpage, Nesha Dushani; Aanesen, Margrethe; Amarasinghe, Oscar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-02)
      This study investigates intended visitation behavior of tourists toward Rekawa wetland under anticipated climate change (CC) scenarios. An interview-based contingent visitation survey was conducted with 365 foreign and domestic tourists to estimate the effects of CC on future visitation. Based on two IPCC scenarios using two direct and three indirect climatic factors, we composed a CC environmental ...
    • Nemo-effekten og koraller 

      Armstrong, Claire W.; Aanesen, Margrethe (Journal article; Tidsskriftartikkel, 2014-05-07)
      Bryr den norske befolkningen seg om dyphavet og de organismer som lever der selv om vi ikke har noen direkte nytte av dem? Er vi villig til å ofre økonomisk aktivitet som fiskeri og oljevirksomhet for beskytte miljøet i dyphavet? Vår studie sier ja.
    • People do care about the deep sea. A comment on Jamieson et al. (2020) 

      Armstrong, Claire W.; Aanesen, Margrethe; Hynes, Stephen; Tinch, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-23)
      In a paper in this journal entitled “Fear and loathing of the deep sea: why don’t people care about the deep sea?”, Jamieson et al. (2020) pose this question and answer it with many interesting perspectives from psychology, ocean literacy and philosophy. However, there is an inherent assumption in the question they ask that people do not care about the deep sea. In order to assess this assumption, ...
    • The Political Game of European Fisheries Management 

      Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-14)
      European fisheries activities are subject to a hierarchy of regulatory authorities. This raises questions regarding the implications of strategic interaction between different authority levels concerning the regulation of these activities. We apply a bio-economic objective function where fishers and regulators have environmental, economic and social preferences, and where fishers are subject to ...
    • Sequential bargaining, external effects of agreement, and public intervention 

      Aanesen, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      In some bargaining situations, agreement has implications for agents beyond the parties involved, and if so, delays in reaching an agreement or failing to reach an agreement, when this would be profitable, may imply significant welfare losses. The question raised in this paper is whether the intervention of a government, who has a positive valuation of agreement and therefore offers a subsidy, will ...
    • Stakeholder Influence and Optimal Regulations: A Common-Agency Analysis of Ecosystem-Based Fisheries Regulations 

      Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      One aspect of ecosystem-based management is to include new stakeholders. When an environmental NGO (ENGO) gets a say in the fisheries management, this will affect the authorities' optimal regulation. Combining a principal-agent model and a steady-state bioeconomic model, we show that under symmetric information the authorities will moderate their use of regulation as a response to the ENGO's increased ...
    • To tell or not to tell: Preference elicitation with and without emphasis on scientific uncertainty 

      Aanesen, Margrethe; Armstrong, Claire W.; Borch, Trude Kristin; Fieler, Reinhold; Hausner, Vera Helene; Kipperberg, Gorm; Lindhjem, Henrik; Navrud, Ståle (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-01)
      Decisions about the optimal use of coastal and marine resources must be taken under high uncertainty about environmental impacts and may conflict with public perception of the risk associated with current blue growth initiatives. In a discrete choice experiment conducted in valuation workshops in five communities in Arctic Norway, we examine public preferences for various aquaculture expansion paths. ...
    • Trading off co-produced marine ecosystem services: Natural resource industries versus other use and non-use ecosystem service values 

      Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-22)
      Ecosystem services (ESs) may be both non-market and market based. Both may provide important input to societal welfare. Using natural resources, or converting nature in the development of market based ES may impact the access to non-market or more conservationist ES, and vice versa. How does the general public trade-off between these two types of ES? We use two valuation studies in Northern Norway ...
    • Use and non-use values in an applied bioeconomic model of fisheries and habitat connections 

      Armstrong, Claire W.; Vondolia, Godwin Kofi; Aanesen, Margrethe; Kahui, Viktoria; Czajkowski, Mikolaj (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)
      In addition to indirect support to fisheries, marine habitats also provide non-use benefits often overlooked in most bioeconomic models. We expand a dynamic bioeconomic fisheries model where presence of natural habitats reduces fishing cost via aggregation effects and provides non-use benefits. The theoretical model is illustrated with an application to cold-water corals in Norway where two fishing ...
    • Valuing coastal recreation and the visual intrusion from commercial activities in Arctic Norway 

      Aanesen, Margrethe; Falk-Andersson, Jannike; Vondolia, Godwin Kofi; Borch, Trude; Navrud, Ståle; Tinch, Dugald (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-04)
      The coastal zone in the Arctic is being extensively used for recreational activities. Simultaneously, there is an increasing pressure from commercial activities. We present results from a discrete choice experiment implemented in Arctic Norway, revealing how households in this region make trade-offs between recreational activities and commercial developments in the coastal zone. Our results show ...
    • What does stakeholder involvement mean for fisheries management? 

      Aanesen, Margrethe; Armstrong, Claire W.; Bloomfield, Helen J.; Röckmann, Christine (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
    • Willingness to pay for mangrove restoration to reduce the climate change impacts on ecotourism in Rekawa coastal wetland, Sri Lanka 

      Salpage, Nesha Dushani; Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-03)
      This study investigates tourist preferences and willingness to pay (WTP) for restoration of mangroves to reduce the effects of climate change (CC) on ecotourism at Rekawa coastal wetland, Sri Lanka, using a double bounded discrete choice elicitation format in a contingent valuation method. The survey also included socio-economic, demographic, and attitudinal characteristics of respondents. The ...
    • Willingness to pay for unfamiliar public goods: Preserving cold-water coral in Norway 

      Aanesen, Margrethe; Armstrong, Claire W.; Czajkowski, Mikolaj; Falk-Andersson, Jannike; Hanley, Nick; Navrud, Ståle (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-17)
      The world's largest concentration of cold-water coral (CWC) is found off the Norwegian coast. Most CWC discoveries are recent, posing new challenges for Norwegian coastal and fishery authorities regarding the management of deep-sea resources. Scientific knowledge of CWC is limited, and many citizens have not even heard about them. This creates problems for the application of the stated preference ...
    • Willingness to pay to protect cold water corals 

      Armstrong, Claire W.; Aanesen, Margrethe; van Rensburg, Thomas; Sandorf, Erlend Dancke (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-16)
      There is increasing pressure to use currently untapped resources in the deep sea, raising questions regarding ecosystem service trade‐offs in these often unknown areas. We assessed the trade‐offs between protection of cold‐water coral reefs and economic activities, such as fisheries and petroleum extraction, through a survey of a representative sample of the populations of Norway and Ireland. ...
