La conférence SUST-BLACK “Sustainable Development at the Black Sea” s’est tenue à Bucarest les 8 et 9 mai 2019, au Palais du Parlement Roumain. Cette conférence est un événement de la présidence roumaine du Conseil de l'UE, soutenu par la Commission européenne. http://www.sust-black.ro/Vue du Palais du Parlement roumain à BucarestDans le cade de cette conférence, l’équipe de la mission archéologique a présenté une contribution sur le thème «&#160;Submerged&#160;Neolithic Landscapes in the Danube Delta ».&#160;À l’occasion de cette conférence sera publiée la «Déclaration de Bucarest» qui lancera le programme de recherche stratégique et d'innovation pour la mer Noire. Des chercheurs et des parties prenantes de pays du bassin de la mer Noire et d’autres pays d’Europe ont déjà apporté d’importantes contributions à ce document, offrant ainsi un excellent exemple de diplomatie scientifique dans ce domaine. Le programme stratégique de recherche et d'innovation pour la mer Noire jouera un rôle majeur dans l'amélioration de la connaissance du bassin marin lui-même, de ses opportunités pour la croissance bleue.Salle de la conférenceRésumé de notre communication :Titre : Submerged Neolithic landscapes in the Danube Delta Delta: geo-archaeological and bio-archaeological approaches around the tell of Taraschina (5000-3500 BC)by Laurent Carozza (1), Costantin Haită (2), Jean-Michel Carozza (3), Adrian Bălășescu (4), Valentin Radu (2), Mihaela Danu (5), Cristian Micu (6), Albane Burens (1)Coasts and deltas are "hot spots" for biodiversity. These environments, subject to global changes, constitute sensitive ecosystems whose management requires a long-term understanding of the mechanisms of formation and functioning. Since 2010, an international research project has been attempting to reconstruct the evolutionary trajectories of one of the largest hydrological complexes: the Lower Danube and its delta.&#160;The Franco-Romanian team initiated a research project focusing on the study of agro-pastoral communities that inhabited the Danube Delta during the 5th millennium BC. This project focuses on the relationships between the Chalcolithic societies of Gumelnița culture and their environment. In the particular context of the Danube Delta, these communities have been exposed to sudden environmental changes, and more specifically to changes in the hydrosystem.&#160;The excavation of the submerged tell of Taraschina, now located in the center of the Danube Delta, is being carried out with a view to rebuilding the link between societies and their environment. In particular, the link between geomorphological - bio-geographic - mobility and adaptation strategies of human communities must be observed. Archaeological horizons provide data that allow us to reconstruct, at high temporal resolution, the impact of these communities on their environment and biodiversity. At the local level, archaeozoological studies dedicated to invertebrates (bivalves and snails) and vertebrates (fish, reptiles, birds, mammals), palynological studies and the analysis of phytoliths have provided very important information to reconstruct the environments and their exploitation. Thus it was possible to highlight cereal processing practices at the Taraschina site and in its surrounding environment. Archaeological data show a succession of crises during the second half of the 5th millennium BC (around 4350-4250 BC and around 4150-4050 BC).1- CNRS UMR 5602 Géographie de l’Environnement (Toulouse) responsable de l’International Research Project «&#160;IRP Geo-archaeology of lower Danube and its delta&#160;»&#160;et mission archéologique Danube2- Musée National d’Histoire de la Roumanie (Bucarest)3- La Rochelle Université, UMR 7266 LIENSs (La Rochelle)4- Académie Roumaine, Institut d’archéologie «&#160;Vasile Pârvan&#160;» Bucarest5- Université Alexandru Ioan Cuza de Iasi, Faculté de Biologie, Département de Recherche Scientifique6- Institut de Recherche Eco-Museal «&#160;Gavrilă Simion&#160;» de Tulcea
