In Gallia Belgica, the southern part of the Menapian and Nervian civitates, as well as the northern part of the Atrebates territory are characterized by multiple landscapes. The analysis of local pottery production illustrates the complexity of the economic relationships and their different expressions of cultural identity, achieved through an integrated approach of macroscopic, petrographic and chemical description of local kiln site material, combined with a systematical identification of pottery from consumption sites. This method permits us to study the pottery distribution patterns and thus an analysis of economic and cultural interaction. In the western part of the studied area the Menapians preserve the traditional indigenous technique of hand-made pottery, while in the eastern part the Atrebates and the Nervians change to wheel-turned pottery and a choice of specific clays by the middle of the first century AD. The reasons for this difference in choices and techniques are multiple, but the land-use plays a fundamental role. The presence of well-adapted clay material, the production of specific delicacies and foodstuffs and the arrival of exogenous populations, are crucial factors leading to this technical contrast. The integrated approach of studying both the consumption and production material also assists in answering questions about the organization of the potter’s production: identification of clay mixtures, the alteration or upholding of certain mixtures, recognition of testing periods and abandoning of clay mixes, specialization and the conservation, transferring or movement of techniques or of potters. These themes can be developed for pottery kiln sites focusing on the production of wheel-turned pottery, sold for its qualities instead of its contents. ; En Gaule Belgique, la partie méridionale des civitates des Ménapiens et des Nerviens ainsi que le nord du territoire atrébate composent une zone caractérisée par des multiples terroirs.
