Geoarchaeology: Where Geosciences Meet the Humanities to Reconstruct Past Human–Environment Interactions. An Application to the Coastal Areas of the Largest Mediterranean Islands

Abstract

The study of past Human–Environment interactions has long been seen at a very local scale, that of sites of human occupation. Geoarchaeology differs from the traditional concepts of Environmental Archaeology and Landscape Archaeology in this respect since it adopts a different spatial resolution based on the development of multidisciplinary research at the scale of geographical, geological or geomorphological features. In this paper, we aim to contribute to the definition of coastal geoarchaeology where environmental holistic studies can be developed, thus integrating both continental and marine dynamics. A specific application is realized here for the largest Mediterranean islands where heterogeneity can be observed in research over the last decades. For this reason, we divide the Mediterranean Basin into four areas in order to review the main works conducted. In general, investigating coastal environments represents an exciting opportunity to reconstruct past landscapes and to evidence the long-term history of human occupation and land use by employing a wide range of proxies. We focus in particular on the coastal wetlands of Corsica, where a large number of lagoons have been cored since the early 2010s. Multiproxy laboratory analyses reveal a history of the complex relationships between past human societies and their environments which is complementary to existing archaeological studies.
