Abstract : Over the centuries society has modified its representation of marine space, moving from the concept of " empty oceans " to that of " saturated seas ".Indeed, in addition to " traditional " established activities (commercial fishing, navigation etc.) have been superimposed the intensification of certain practices (extraction of marine aggregates, leisure navigation etc.) and also new activities which, until now, have been purely terrestrial or coastal but which are destined for development in the open sea (marine renewable energy, offshore aquaculture etc.). In the face of these new developments, the necessity of conserving the marine environment has also encouraged the multiplication of marine protected areas (marine nature parks, Natura 2000 sites, etc.). There is thus an increase in the demand for maritime space which the actual availability of space cannot respond to, outside of integrated management enabling the cohabitation between all the various maritime activities. But the particularities of maritime space call for a specific approach. Nowadays, Integrated Coastal Zone Management (ICZM) is a procedure which is recognized at an international level in response to these issues. But its applications are still too often limited to an experimental stage and the feedback on experiments show that they are limited to coastal land or to confined maritime spaces.It is in this context that Maritime Spatial Planning (MSP) would seem to be useful, enabling the extension of the principles of ICZM towards the sea. After studying the implications of MSP, in particular thanks to the analysis of existing experiences at an international level, this thesis focuses on an evaluation of the position of France in relation to MSP in the context of the elaboration of its strategy of Integrated Management of the Sea and Coastline (IMSC).The theoretical aspects of MSP are compared to the conditions on the ground at different levels and, in particular, to those of the maritime basin of Lorient.This approach enables the identification of key elements and issues related to the application of MSP in the context of metropolitan France.
