Total marine fisheries extractions by country in the Baltic Sea: 1950-present

Abstract:This article aims at contributing to governance conceptualization and its application to case study analyses. Two of the challenges which the theoretical and empirical work in the article addresses concern the facilitation of comparability of diverse governance cases and a specification of several key mechanisms of governance formation and reform. A proposed model of the architecture of governance systems -their major components and inter-linkages -contributes, as argued and illustrated here, to greater comparability among cases and with the possibility of improved accumulation of knowledge about governance systems. These tools are applied to empirical cases of governance structure and their functioning and reformation. Baltic fisheries, a complex, multi-level case of commons governance, is considered in some detail in order to illustrate and elaborate the key factors of power, knowledge, and conflict in the functioning and transformation of governance systems. In addition to the Baltic fisheries case, we consider briefly for comparative purposes chemicals and gender relations as additional areas of EU governance. The paper is divided into four sections. Section I introduces the basic conceptualization and tools of analysis. Section II presents the case of Baltic fisheries. Section III elaborates the key concepts and tools presented in Section I, in particular considering additional cases of the functioning of governance systems. Section IV is a brief conclusion.

Legal requirement in Europe asks for Ecosystem-Based Fisheries Management (EBFM) in European seas, including consideration of trophic interactions and minimization of negative impacts of fishing on food webs and ecosystem functioning. This study presents the first mass-balanced ecosystem model focused on the western Baltic Sea (WBS). Results show that heavy fishing pressure exerted on the WBS has forced top predators such as harbour porpoise and cod to cover their dietary needs by shifting from forage fish to other prey or find food outside of the model area. The model was then developed to explore the dynamics of four future fishery scenarios: (1) business as usual (BAU), (2) maximum sustainable fishing (F = FMSY), (3) half of FMSY, and (4) EBFM with F = 0.5 FMSY for forage fish and F = 0.8 FMSY for other fish. Simulations show that BAU would perpetuate low catches from depleted stocks with a high risk of extinction for harbour porpoise. In contrast, the EBFM scenario would allow the recovery of harbour porpoise, forage fish and cod with increases in catch of herring and cod. EBFM promotes ecosystem resilience to eutrophication and ocean warming, and through the rebuilding of commercial stocks increases by more than three times carbon sequestration compared to BAU. The model provides an interrelated assessment of trophic guilds in the WBS, as required by European law to assess whether European seas are in good environmental status.
