    • Prospects for Valuation in Marine Decision Making in Europe 

      Tinch, Rob; Hynes, Stephen; Armstrong, Claire W.; Chen, Wenting (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12)
      There is now high-level recognition that the UN Sustainable Development Goals can only be achieved if the decline of ecosystems and biodiversity can be halted and reversed. This will require effective control of ongoing pressures, meaningful protection and enforcement of protected areas, and significant investments in ecosystem restoration. This paper explores the possible use of economic valuation ...
    • Public Perceptions of Deep-Sea Environment: Evidence from Scotland and Norway 

      Ankamah-Yeboah, Isaac; Xuan, Bui Bich; Hynes, Stephen; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-10)
      Knowledge of people's understanding of environmental problems is vital for the effective implementation of the ecosystem approach to marine management. This is especially relevant when conservation goals are aimed at ecosystems in the deep-sea that are remote to the consciousness of most people. This study explores public perceptions of the deep-sea environment among the Scottish and Norwegian public. ...
    • Rebuilding the Northeast Arctic Cod Fisheries - Economic and Social Issues 

      Armstrong, Claire W.; Eide, Arne; Flaaten, Ola; Heen, Knut; Kaspersen, Inga Wigdahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      The Northeast Arctic cod (NEA cod) fisheries in Norway are now one of the richest cod fisheries in the world. In the past the fishery has experienced several stock declines and low economic returns. In this paper we review management approaches applied over 20 years to address one of the most severe crises in the fishery. Emphasis is on management strategies and the measures carried out to ensure ...
    • A review of bioeconomic modelling of habitat-fisheries interactions. 

      Foley, Naomi; Armstrong, Claire W.; Kahui, Viktoria; Mikkelsen, Eirik Inge; Reithe, Siv (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of ...
    • 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 ...
    • Subjective well-being and stated preferences: Explorations from a choice experiment in Norway 

      Vondolia, Godwin Kofi; Hynes, Stephen; Armstrong, Claire W.; Chen, Wenting (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-01)
      Subjective well-being valuation has recently grown in use with applications in the fields of environment, health, and cultural heritage. With this methodology values are based on how non-market goods impact on self-reported measures of well-being such as life satisfaction. Despite the differences in theoretical foundations of subjective well-being and preference-based valuation methods, recent ...
    • 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 ...
    • Trading off Tourism and Fisheries 

      Bui, Bich Xuân; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-22)
      This paper presents a deterministic bioeconomic model in which the creation of a marine protected area (MPA) is not only a fisheries management tool but also introduced in order to provide tourism amenity benefits. The theoretical model is illustrated with analysis of the Nha Trang Bay (NTB) MPA in Khanh Hoa province in Vietnam, where the anchovy purse seine fishery is considered. An amenity value ...
    • Trading Off Tourism for Fisheries 

      Xuan, Bui Bich; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-22)
      This paper presents a deterministic bioeconomic model in which the creation of a marine protected area (MPA) is not only a fisheries management tool but also introduced in order to provide tourism amenity benefits.

    • 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 blue carbon changes in the Arctic ocean 

      Armstrong, Claire W.; Foley, Naomi; Slagstad, Dag; Chierici, Melissa; Ellingsen, Ingrid H.; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-25)
      The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO<sub>2</sub> supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and not yet estimated for the Arctic Ocean. With the severe climatic changes in the Arctic Ocean, impacting sea ice and potentially the vertical carbon transport mechanisms, ...
    • Valuing High Seas Ecosystem Conservation 

      Bui, Bich Xuân; Armstrong, Claire W.; Ankamah-Yeboah, Isaac; Hynes, Stephen; Needham, Katherine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
      The high seas provide a variety of ecosystem services that benefit society. There have, however, been few attempts to quantify the human welfare impacts of changes to the delivery of these benefits. We assessed the values of several key ecosystem service benefits derived from protecting ecosystems in the high seas of the Flemish Cap through choice experiments conducted in Canada, Norway, and Scotland. ...
    • Valuing the ecosystem service benefits from kelp forest restoration: A choice experiment from Norway 

      Hynes, Stephen; Chen, Wenting; Vondolia, Godwin Kofi; Armstrong, Claire W.; O'Connor, Eamonn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-08)
      Habitat loss and degradation are recognised as the most important causes of species decline and extinction in marine ecosystems. It is also widely recognised that a range of restoration actions are now essential to halt further decline. From a policy perspective, demonstration that restoration activity is in the interest of society is an important goal. In this paper, the welfare impacts of restoring ...
    • 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. ...
