By focusing on an extended chronology, and relying on the update of known and new archaeological and palaeonvironmental sequences, PAL investigates how the Alimini Lakes disctrict (Apulia, S Italy) has changed over the past 10ka (the Holocene), a period witnessing great climatic environmental and social change. Holocene climate change is amplified in coastal wetlands, greatly affecting hydrology vegetation and people. Likewise, socio-economical changes (e.g. the introduction of agriculture) play a fundamental role in the shaping of wet landscapes. Under the combined action of environmental and human factors, coastal wetlands are prone to rapid and drastic ecological shifts and constitute ideal locations for developing a geoarchaeological approach. The results of the first year of research are presented here and include (1) the visit, description and GPS positioning of previously and newly discovered archaeological areas (cave and open air sites), (2) sampling of two Holocene sedimentary sequences from the Alimini Lakes disctict, (3) the results of the preliminary analyses (including AMS radiocarbon dating) carried out on the samples. The relocation of new and previously found archaeological sites was necessary to overcome some confusions caused by the contrasting published information. Relocated archaeological sites were normalized in a GIS environment. Two main Pleistocene/Holocene palaeoenvironmental sequences were sampled within the Alimini Lakes district: (1) the Frassanito dune reference sequence, obtained from a portion of the coastal dune (up to 10 m high) bordering the trait of the Adriatic coast situated in front of the Alimini lakes, (2) the ALI G 1 core (9m long) sampled on the W shore of Alimini Grande Lake. The multiproxy study of these sedimentary sequences provides a record of Holocene environmental changes that allows contextualizing the local signature in the wider central and eastern Mediterranean region, by comparison with published and ongoing studies of similar Mediterranean wetlands. These data, correlated to the archaeological record available for the wider central Mediterranean region, will allow the understanding of the differences between human response to climate change and anthropogenic impact on the environment at the local and regional scales.

The original Upper Pleistocene hillslope has been dissected by deep gullies leaving relict slope pediments. Holocene filling of the Basento river valley and gullies occurred as a succession of downcut and fill episodes. A first phase of accumulation occurred in the Late Neolithic, which was followed by a downcutting between 4500 and 3700 cal. yr BP. A second deposition phase took place in the Greek–Roman period between 2800 and 1620 cal. yr BP, which was interrupted at around 2500 cal. yr BP. Another downcutting phase took place between 1620 and 1500 cal. yr BP, followed by a deposition phase between 1440 and 1000 cal. yr BP. After 1000 cal. yr BP a deep downcutting took place. Evidence collected with this study, coupled with climate data recorded in other Italian and European locations, suggests that filling and downcutting episodes in Fossa Bradanica were predominantly climate-driven. Anthropogenic impact only intensified or weakened these processes.
