Management Forcing Increased Specialization in a Fishery System

Adaptations and well-being: Gulf of Alaska fishing families in a changing landscape

Over the last three decades, fishing families in the Gulf of Alaska have adapted to numerous multifaceted conditions in response to near constant flux in stocks, markets, governance regimes, and broader sociocultural and environmental changes. Based on an analysis of seven focus groups held across Gulf of Alaska fishing communities, this study explores the variety of strategies that families across the Gulf have employed to adapt to changing conditions from the 1980s to the present day. Furthermore, the study examines how those strategies have evolved over time to accommodate cumulative effects and synergisms. While families continue to employ long-standing adaptation strategies of fisheries portfolio diversification and increasing effort, they are also integrating new adaptations into their framework as changing management systems, demographics, and technologies shift how choices about adaptations are made. This study also demonstrates how adaptations have implicit intra- and inter-personal well-being tradeoffs within families that, while potentially allowing for sustained livelihoods, may undermine other values that individuals and families derive from fishing.

An empirical model of the Baltic Sea reveals the importance of social dynamics for ecological regime shifts

Regime shifts triggered by human activities and environmental changes have led to significant ecological and socioeconomic consequences in marine and terrestrial ecosystems worldwide. Ecological processes and feedbacks associated with regime shifts have received considerable attention, but human individual and collective behavior is rarely treated as an integrated component of such shifts. Here, we used generalized modeling to develop a coupled social-ecological model that integrated rich social and ecological data to investigate the role of social dynamics in the 1980s Baltic Sea cod boom and collapse. We showed that psychological, economic, and regulatory aspects of fisher decision making, in addition to ecological interactions, contributed both to the temporary persistence of the cod boom and to its subsequent collapse. These features of the social-ecological system also would have limited the effectiveness of stronger fishery regulations. Our results provide quantitative, empirical evidence that incorporating social dynamics into models of natural resources is critical for understanding how resources can be managed sustainably. We also show that generalized modeling, which is well-suited to collaborative model development and does not require detailed specification of causal relationships between system variables, can help tackle the complexities involved in creating and analyzing social-ecological models.
