Climate resilience and risks of rigidity traps in Iceland’s fisheries

Iceland’s fisheries system is well-governed, data-rich, and has adapted to past ecological change. It thus provides an opportunity to identify social-ecological attributes of climate resilience and interactions among them. We elicited barriers and enabling conditions for adaptation in Iceland’s fisheries from semi-structured expert interviews, using projections of fish habitat shifts by mid-century to guide discussion. Interviewees highlighted flexible management, highly connected institutions that facilitate learning, ample assets to expand adaptive options, and cultural comfort with change. However, examining how these attributes interact in reinforcing feedback loops revealed potential rigidity traps, where optimization for resilience to stock shifts may render the system more vulnerable to extreme environmental change and social backlash. This study articulates resilience attributes that Iceland and other fisheries systems might prioritize as the climate changes. It further explores circumstances in which these same attributes risk forming traps, and potential pathways to escape them.
