Anthropogenous savannas on the French Guiana coast

Stéphen Rostain (CNRS/Panthéon-Sorbonne University)

Abstract

Coastal savannas of French Guianas are covere by thousands of raised fields, built between 900 and 1400 AD by Arauquinoid groups. Stereoscopic analyses and surveys resulted in a complete and precise map of the Pre-Columbian earthworks along the western French Guiana coast, from Cayenne Island to the Maroni River. Topographical location and the shape of fields is indicative of differences in adaptation to the hydrographical conditions and to the nature of the soil. Some hydrological constructions are associated with the raised fields. Other earthworks are found like causeways that cut through the swamps. Residential sites also show complex internal organization. Ancient communities did manage their territory in specific pattern. French Guiana coastal landscapes not only result from natural process, but also from old human activities.
