Modélisation qualitative des socio-écosystèmes marins en appui à la conservation de la biodiversité

Abstract : The gulf of Morbihan has remarkable marine habitats. They provide ecosystem services favoring the development of human activities. The gulf can thus be considered as a social-ecological system to look at the interactions between uses and marine habitats. Two participatory modeling approaches are implemented to reflect on the conservation of mudflats and Zostera meadows. The first is based on qualitative modeling, through the co-construction of models with scientific experts and local actors. These models are analyzed mathematically in order to look at the responses of the variables of the system following disturbances. The second involves agent-based modeling. Several UML diagrams are constructed in order to reveal the behavior of a user when faced with the introduction of a management measure. The modeled measures are the establishment of a fallow in a recreational shellfish fishing area and the installation of ecological moorings near an island. Qualitative modeling makes it possible to obtain results against scenarios without using quantitative data. UML diagrams show the data needed to evaluate management measures. These two approaches then provide complementary visions to better understand the conservation of marine habitats.
