| In the marine environment, positive law generates multiple zones and regulatory limits that overlap in space, justifying a cartographic representation as a relevant approach to promote understanding (synthetic vision), analysis (highlighting legal anomalies, inconsistencies and redundancies), dissemination and communication to different audiences (awareness-raising). The article presents a methodology leading to the mapping of marine and coastal environmental law in West Africa, using a geographic information base to produce static or interactive cartographic representations via a Geographic Data Infrastructure (GDI). It shows the contribution of this type of mapping to a transversal approach in a multi-activity, multi-sectoral and multi-scale context. A... |

| Between December 2013 and March 2014, a cluster of about 12 storm events hit the coast of Brittany with an exceptional frequency. It was in February that these storm events were the most frequent and particularly virulent. The significant wave heights measured off Finistere reached respectively 12.3 m and 12.4 m during Petra and Ulla storms on February 5 and 14. However, analysis of hydrodynamic conditions shows that only three episodes promoted extreme morphogenetic conditions because they were combined with high spring tide level. The first one occurred on January 1 to 4, it was followed by events from February 1 to 3, and March 2-3. During these three extreme events observed tide levels were above highest astronomical tide level (HAT). Maximum surge... |

| For many conservation scientists, interdisciplinarity and participation can be efficient in the management of biodiversity. For both methods, new tools and new participative processes such as the so-called co-modeling process are required. The key questions addressed in this article are how group dynamics shape the model and why certain perspectives dominate in a process designed to be democratic. It is necessary, therefore, in order to appreciate the design and the legitimacy of the model that has been co-constructed, to address the questions of both the stakeholders' interests and their status in the process. Our case study is a co-modeling program based in a French biosphere reserve. It enabled us to highlight the key role of the mediator who had to... |
