Our understanding of the Later Stone Age (LSA) on the Greater Mapungubwe Landscape has until now been fairly limited. However, it is a landscape upon which foragers witnessed and partook in agriculturalist state formation between AD 900 and 1300, altering their cultural behaviour to suit their changing social and political topography. Nowhere else in southern Africa were foragers part of such developments. For this project a landscape approach was used to study the various changes in the regional LSA record as well as the way in which foragers interacted with farmers. In order to address these issues, data were obtained from an archaeological survey followed by an excavation of seven sites in north-eastern Botswana, part of the Greater Mapungubwe Landscape. These finds indicate that the local forager record varies chronologically and spatially, which had not previously been recorded. Foragers also used a variety of site types and in each a different forager expression was deposited, providing indications of their changing settlement pattern. Notably, this included a gradual movement into agriculturalist homesteads beginning by at least AD 1000 and concluding by AD 1300, when the Mapungubwe capital was abandoned. Thus, interactions, at least in some cases, led to assimilation. There is also clear evidence of exchange with agriculturalists at many of the excavated sites, but this does not always seem to be related to their proximity with one another. Performing a landscape study has also made it possible to make two general conclusions with regard to LSA research. First, these data challenge ethnography, displaying its limitations particularly with linking modern Bushman practices, such as aggregation and dispersal patterns or hxaro gift exchange, to LSA foragers. Second, a full landscape understanding combines the archaeology of multiple cultural landscapes and in this case also crosses national borders, two themes often neglected in southern African archaeological studies.

L’approche géoarchéologique a pour objectif de discuter l’intérêt des archives sédimentaires des rammadiyat pour appréhender les dynamiques d’occupation des sols au Capsien et Néolithique. Les rammadiyat se présentent sous forme de monticules dont la stratigraphie est peu exprimée. Les fouilles récentes ont mis en évidence des sols d’occupation renouvelant les questionnements sur les modes d’occupation de ces populations capsiennes. L’approche géoarchéologique repose sur la micromorphologie des sols. Elle a été menée sur 5 sites capsiens de Tunisie et d’Algérie. Elle a permis de caractériser les modes de formation de ces rammadiyat. Les informations recueillies montrent que les rammadiyat relèvent principalement des processus liés aux activités humaines, qui ont interagi à des degrés variables avec les processus naturels. Elles ont permis de construire un modèle qualitatif de la dynamique de formation des rammadiyat, exprimé par une classification des faciès sédimentaires identifiés, selon les pratiques d’aménagement, selon les activités et selon le degré de fréquentation. Ce modèle met en évidence un premier schéma de l’organisation spatiale des sols d’occupation, matérialisant trois types espaces : un espace construit (bâtiment), un espace de cour segmenté avec des aires domestiques, voies de passage et zones de rejets et un espace peu fréquenté, en marge de l’occupation principale. L’enregistrement sédimentaire témoigne d’un mode d’occupation continu, localement rythmé par des variations dans le degré de fréquentation. Des épisodes d’abandon temporaire ou de très faible fréquentation sont ainsi observés. Cependant, leur généralisation à l’ensemble du site reste à préciser. / The aim of the geoarchaeological approach is to discuss the interest of sedimentary archives of rammadiyat, in order to understand the dynamics of soil occupancy at the Capsian and Neolithic period. The rammadiyat present the shape of a small mound, whose stratigraphy is quite undifferentiated. Recent excavations show the presence of occupation surfaces, renewing the questions about the settlement strategies and of these capsian populations. The geoarchaeological approach is based on soil micromorphology .This research was conducted on 5 capsian sites in Tunisia and Algeria and allowed us to characterize the formation processes of these rammadiyat. The collected data show that rammadiyatis mainly formed by anthropic processes related to human activity interacting with natural processes on varying degrees. It’s then possible to construct a qualitative model relating to the formation dynamics of rammadiyat, expressed by a classification of the identified sedimentary facies, according to the building practices, the activities and the intensity of human occupation. This model highlights a first framework of the spatial organization of occupation surfaces, materializing three types of spaces: a built space (dwelling), a segmented yard space with domestic areas, passageways and dump areas, and a marginal area, showing a sporadic occupation. The sedimentary record shows a continuous occupancy, locally punctuated by variations in the intensity of human occupation. Episodes of temporary abandonment or very low occupation are observed. However, their generalization to the whole site remains to be clarified.
