Abstract : In coastal areas, a lot of human conflicts arise both from intense and numerous human uses that may be antagonistic. Even if these competitions for space or for resources take different forms, they may constitute an obstacle for any territorial management strategies. Actually, if these conflicts may be viewed as change promoters, they are also used by the stakeholders themselves to promote a statu quo. Beyond the social aspect of this issue, as traditionally investigated by most of the geographers, this subject area has an important spatial dimension. Explaining the spatial and the temporal processes from which these conflicts arise may be a good way to anticipate and even solve them. Keeping this in mind, this thesis aims at providing concepts and tools to suitably analyse different conflicts of use in a spatial perspective. We first defined the concepts used in this work, and analysed the different existing methods. This bibliographical analysis revealed what could be a spatial approach of the uses conflicts. Secondly, through the example of the Bay of Bourgneuf (Pays-de-Loire, France), the identification and the analysis of spatial structures allowed us to highlight different examples of interactions that generate conflicts. Thanks to this first step, we built a spatial conceptual model revealing the origins of uses conflicts. Taking this into account, particular studies were conducted on different themes: anchorage planning, oyster farming, interactions environment/ recreational shellfishing). These studies were conducted to assess the relevance of the different spatial modelling tools for interaction analyses. Different tools were used in this part of our work, including choremes, individual-based, creations of spatial databases, and algorithms. To put use cases of concepts and tools in an obvious place, we finally formalise the link between the spatial approach of uses conflicts and the development of geopropective.
