How global change challenge coordination amongst action situations in coastal systems: a case study from Languedoc, France

Therville C., Brady U., Barreteau O., Bousquet F., Mathevet R., Dhenain S., Grelot F., Anderies J.M.. 2017. In : Resilience 2017. Stockholm : s.n., p. 398-399. Resilience 2017 : Resilience frontiers for global sustainability, 2017-08-20/2017-08-23, Stockholm (Suède).

Coastal areas around the world are facing multiple challenges leading to diverse adaptations to manage their vulnerability. Since coastal regions represent complex social-ecological systems (SES) that are characterized by high interdependency among individual components, adaptations can have a wide range of positive and negative consequences. To better anticipate these feedbacks and identify interdependencies among multiple components of a SES, frameworks of analysis can be particularly useful. We used Anderies et al.'s (2004, 2015) Robustness Framework to analyse a case study located along the Languedoc coastline in southern France. Through the examples of land-use planning and coastal management policies, we identified the main changes taking place, the responses to those changes, and resulting consequences at the system scale. We found that the presence of multiple, interacting global changes place growing pressure upon resources and infrastructures, leading to a redefinition of social organization. The study highlights the importance of envisioning coastal SES at multiple scales and considering them as a combination of nested and interdependent feedback systems where choices made in separate decision-making contexts will have cross-scale implications for the whole SES. This modular configuration can be seen as a network of adjacent action situations and raises challenges about the definition of modules' boundaries and coordination. Refining the robustness framework with additional institutional analysis can be helpful to analyze multiple interdependencies, to foresee consequences of adaptation in inter-related decisional contexts, and to promote collective action to cope with global change along coastlines.
