Résumé : International audience
Coral reef resource systems are complex adaptive social-ecological systems providing vital and valuableecosystem services for human societies such as food provision, coastal protection and recreational activities.Their sustainability is questioned in many places around the world as they experience combined effects ofmultiple chronic anthropogenic and natural drivers at local to global scales. From a management perspective,there is a crucial need to understand how the impact of these drivers cascade through the social-ecologicalsystem components. This study develops a transdisciplinary and participatory approach to investigating thesocial-ecological dynamics of a Polynesian coral reef coastal system. A preliminary conceptual model using theDriver-Pressure-State-Impact (DPSI) framework is first being built through participatory modeling workshops.Then, pressure-state relationships are assessed with the help of empirical datasets as a first step towards thevalidation of the DPSI model. Results shows striking social-ecological interactions with different patterns in thelagoon and in the fore reef. Local management should be: (1) less resource-focused to account more specificallyto the existing typology of actors; (2) more spatially-explicit to better distinguish management objectives andactions for the lagoon and the fore reef sub-systems; and (3) more coordinated with terrestrial agencies for acoherent land-sea connection and integration that would both (i) account for existing land-sea interactions and(ii) better reflect the Polynesian cultural heritage that considers nature from ridge to reef as a whole. Suchconceptual models of social-ecological systems are a useful tool to build exploratory scenarios to ultimatelysupport planning decision-making processes.

Résumé : International audience
As climate change continues to impact socio-ecological systems, tools that assist conservation managers to understand vulnerability and target adaptations are essential. Quantitative assessments of vulnerability are rare because available frameworks are complex and lack guidance for dealing with data limitations and integrating across scales and disciplines. This paper describes a semi-quantitative method for assessing vulnerability to climate change that integrates socio-ecological factors to address management objectives and support decision-making. The method applies a framework first adopted by the Intergovernmental Panel on Climate Change and uses a structured 10-step process. The scores for each framework element are normalized and multiplied to produce a vulnerability score and then the assessed components are ranked from high to low vulnerability. Sensitivity analyses determine which indicators most influence the analysis and the resultant decision-making process so data quality for these indicators can be reviewed to increase robustness. Prioritisation of components for conservation considers other economic, social and cultural values with vulnerability rankings to target actions that reduce vulnerability to climate change by decreasing exposure or sensitivity and/or increasing adaptive capacity. This framework provides practical decision-support and has been applied to marine ecosystems and fisheries, with two case applications provided as examples: (1) food security in Pacific Island nations under climate-driven fish declines, and (2) fisheries in the Gulf of Carpentaria, northern Australia. The step-wise process outlined here is broadly applicable and can be undertaken with minimal resources using existing data, thereby having great potential to inform adaptive natural resource management in diverse locations.
