Creator:: Paulsen, Harmony
Abstract:: Human adaptation to change is an essential determinant in the resilience of complex social-ecological systems. In the field of water policy and management it has become increasingly clear that traditional government actors cannot fully address emerging water problems at every scale given a demonstrated lack of resources, increasing variability in...

Creator:: Ravn-Jonsen, Lars, Andersen, Ken H., and Vestergaard, Niels
Abstract:: Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...

Creator:: Poudel, Diwakar and Steinshamn, Stein Ivar
Abstract:: This study investigates optimal catch of Barents Sea stocks, namely Northeast Arctic Cod and Capelin in multispecies ecosystem. We solve a multispecies age structured bioeconomic model for predator-prey interaction. Barents Sea stock data from ICES are employed for model application. Among others, we also include sustainability constraint in the model...

Abstract:: The paper puts forward a model of the Pearl River Delta (PRD) fishery in the South China Sea that integrates the ecological, social and economic costs and benefits of fisheries activities in a multidisciplinary framework. In particular, In particular, we developed integrated model by linking a regional Social Accounting Matrix...

Creator:: Abbott, Joshua K. and Fenichel, Eli P.
Abstract:: Fisheries sustainability is a much sought-after goal. Yet, “sustainability” is often too ambiguously defined to be of much practical guidance to policymakers. Furthermore, fisheries managers are increasingly expected to assess and manage fisheries in an “ecosystem-based” manner – accounting for the ecological interdependencies of species and their coupling with the...

Full Text:: Comprehensive Fishery Wealth: A Bioeconomic, Ecosystem- Based Approach to Measuring Fisheries Sustainability

Creator:: Hutniczak, Barbara
Abstract:: Multispecies fisheries pose a considerable management difficulty with respect to quota allocation between species. Externalities of direct control over the harvest may include, among others, creation of unbalanced predator‐prey relationships in the environment. That, in turn, may affect the individual economic incentives of fishing vessels. Combining economic and ecological factors...
