Production in the Barents Sea Fisheries

As climate change impacts and reshapes ecosystems, human responses and associated socio-ecological effects will likely rival the direct effects. It is thus imperative to bring forward an integrated, quantitative understanding of feedbacks and factors in ecosystem service provision. Relevant indicators serve both as measures for social cost-benefit analysis and as measures of the productive capacity of socio-ecological systems. Sustainability requires maintenance of this productive capacity. High-level considerations as these require a detailed and cross-disciplinary research program to promote a detailed understanding of the value creation process, and the present project will contribute to such an understanding for the Barents Sea ecoregion.

 
We aim to establish production or profit functions for the main fisheries in the Barents Sea. The background is the recent interest in calculations of marine ecosystem wealth measures. This interest is grounded in the need to support ecosystem-based management regimes with measurable indicators for assessing management tradeoffs between species, fisheries, and ecosystem services. Indicators that measures the value to society that is created through more comprehensive and inclusive management schemes are needed to fulfil objectives of sustainable and rational use of marine resources. Further, such indicators provide EBM decision makers with concrete measures of progress.
