ABSTRACT. We seek to contribute to the scholarship on operationalizing resilience concepts via a working resilience indicator framework. Although it requires further refinement, this practical framework provides a useful baseline for generating awareness and understanding of the complexity and diversity of variables that impinge on resilience. It has potential value for the evaluation, benchmarking, monitoring, and reporting of marine system resilience. The necessity for such a framework is a consequence of the levels of complexity and uncertainty associated with climate change and other global change stressors in marine socialecological systems, and the problems involved in assessing their resilience. There is a need for: (1) methodologies that bring together knowledge from diverse sources and disciplines to investigate the complexity and uncertainty of interactions between climate, ocean, and human systems and (2) frameworks to facilitate the evaluation and monitoring of the social-ecological resilience of marine-dependent sectors. Accordingly, our main objective is to demonstrate the virtues of combining a case study methodology with complex adaptive systems approaches as a means to improve understanding of the multifaceted dynamics of marine sectors experiencing climate change. The resilience indicator framework, the main product of the methodology, is developed using four case studies across key Australian marine biodiversity and resource sectors already experiencing impacts from climate and other global changes. It comprises a set of resilience dimensions with a candidate set of abstract and concrete resilience indicators. Its design ensures an integrated approach to resilience evaluation.

Non-compliance is a tenacious problem in recreational fisheries management, posing a risk to marine conservation and socio-ecological systems by, for example, undermining management efforts and creating conflict between resource user groups. In fisheries management, deterrence-based approaches have traditionally been used to tackle non-compliance. However, enforcement is often limited in recreational fisheries and an alternative approach is needed to improve compliance. In this paper, we explore the lessons from behavioural economics and apply nudge theory as the basis of alternative management approaches. Nudge theory argues that through positive reinforcement or indirect suggestion, voluntary compliance can be achieved. We test the influence of a nudge, based on a descriptive social norm, through an economic laboratory experiment in a recreational fisheries context. Our results show that the presence of this nudge can increase compliance behaviour by 10%. We find that a nudge was more effective when deterrence is low, but its effects become weaker when deterrence is already high. We also find heterogeneity across individual’s responses to the nudge and risk preferences significantly related to compliance behaviour. Nudges based on social norms have the potential to complement traditional deterrence methods and could prove successful as a cost-effective compliance tool in the marine environment.
