Abstract
Estuaries and coastal zones refl ect confl icting processes due to their
positions at the interface between terrestrial and marine environments.
The estuary of the Seine is an example of such a continuum and is affected
by numerous human activities. Although degradation started in the middle
of nineteenth century, the Seine estuary remains an important area for
biodiversity as well for the food web involving fi sh and birds. The estuary
area has been affected by intense historic anthropogenic pressures and,
more recently, by new human activities, including harbour extension,
aggregate extraction and the development of offshore wind farms.
Nowadays, harbour projects continue to highlight the existing ecological
compartments and are still studied independently. French and European
regulations, including reforms of the harbour status, should ensure a better
integration of natural heritage protection into the integrated coastal zone
management process. However, there is a paradox between the declaration
of the French state, which encourages a global management plan for the
Seine Estuary, and sectoral territorial approaches adopted by the managers. This paper presents an analysis of the current contrasted situation in
the administration of territories, which favours sectoral management
rather than a unique ecosystem-based management process.

Introduction
The Seine estuary represents a territory associated
with dense activities, but which remains an area
of exceptional natural heritage, corresponding to
a space of numerous confl icts crystallising
many different interests: industrial and harbour
activities, fi shing, aggregate extraction, tourism
and agriculture. Multiple actors are concerned:
