This book results from the joint organization of the XXXVII Rencontres Internationales d’Archéologie et d’Histoire of Antibes and the XIIth Colloquium of the Ager Association. Its main objective is to contribute to the understanding of coastal settlements in light of the exploitation of maritime resources. The aim is to seek a better understanding of the exploitation (i.e. the production and its processing methods) of coastal environments understood as an interface between the land and the sea, and the role of production, circulation and maritime trade for settlements and territorial organization. The land and the sea form two natural spaces with different qualities and discontinuous bioecological systems, yet they create a hybrid environment : human settlements and activities in coastal lands often both reflect and profit from this situation. This volume also paid attention to the distinction between amphibious territories (benefiting from two elements: marshes, lakes and lagoons coastal and rivers, meadows flooded by the sea…) and mixed economies in which communities integrate fishing practices and into their operating systems, which are also agricultural and pastoral.
