Abstract english

Ocean acidification (OA) describes a change in the ocean's carbonate chemistry. Whereas its chemical processes are largely understood, the biological and socioeconomic consequences particularly in relation to fisheries are less known. Norway is a major fishing nation worldwide and is potentially affected by OA. To improve the understanding of the socioeconomic consequences of OA, we conducted a risk assessment among the Norwegian counties using a modified version of a risk assessment framework introduced in the Intergovernmental Panel on Climate Change's "Special Report: Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation," which considers risk to be the sum of hazard, exposure, and vulnerability. Our results show that about 13 of 19 counties are likely to experience moderate to high risk from OA. We highlight that the success of integrated risk assessments highly depends on the availability of detailed environmental, economic, and societal data. In the case of Norway, modeling data regarding the progress of OA, improved information on potential biological impacts on a larger number of species, and statistical data on social variables are required. We conclude that although still in its infancy, integrated risk assessments are important prerequisites for any form of interdisciplinary research on OA and the development of successful response strategies.
