Documenting and learning from past transitions helps policy‐makers cope with such challenges. The agricultural revolution in Cantabrian Spain (ca. 7000 cal a bp) was one major adaptation of hunter‐gatherers to a changing environment that started with the Last Glacial Maximum (ca. 24 000 cal a bp) and lasted until the Mid‐Holocene (ca. 5300 cal a bp). Classic approaches to documenting prehistoric cultural timelines are based on manufacturing and technology, thus limited in their ability to describe the sustainability of past societies. Energy regimes, a functional societal approach independent from time, investigate and consider patterns of resource and energy use in various cohabiting and cooperating cultural phases. To examine past energy regimes, a database of archaeological remains was compiled to document four indicators: mobility, e...

The results show a sedimentary recordinterpreted as a model of very short occupation settlement (from Cal BC 5360 to 5225 to Cal BC 4480 to 4865), with abundance ofrests of ceramics “a la almagra” (red ochre) and impressed potteries without Cardium features, as well as lithic and in bone industries. The assemblage has been characterized as Ancient Neolithic from the South of the Iberian Peninsula

In order to reconstruct the palaeogeographic evolution of the alluvial area of Itálica during the second half of the Holocene, our research has focused on the study of the fluvial paleoforms and the alluvial soil-sedimentary sequence, with special emphasis on the analysis of the geoarchaeological records. Ancient maps and aerial photographs of various scales and diverse dates have been interpreted. Borehole cores and profiles, manually or mechanically opened, have also been done to obtain samples for laboratory tests of the representative floodplain soils and sediments. The chronologies provided by the archaeological record were completed with several radiocarbon dates. From these results we propose a possible solution at a local level to the traditional discussion about the existence and location of the ancient harbour of Italica; and for the alluvial plain as a whole, a double alternating palaeogeographic sequence trending to millennial-submillennial scale has been reached. The first one occurring controlled by hydrologic and climatic factors, modulated by a prolonged and extended human pressure on the basin, and showing a succession of four main stages characterized by the predominance of alluvial filling (4833-3206 cal BP; 3130-1989 cal BP; 1620 cal BP-XI century AD; and around the last 500 years), which are separated by periods of stability that favored alluvial soils formation; meanwhile, the second sequence presents short-time terms prone to riverbed design shifting (period prior to Late Bronze; Roman-republican era; central Middle Age), also separated by lengthy phases of morpho-hydrographic stability. In the latter case the main factor does not seem to be, as in the first of those, hydro-climatic shifts and land use changes, but rather the last small regional fluctuations of sea level that came with the second part of the Holocene.

Nineteen hand cores and three mechanical drill cores allowed reconstructing the history of infill. Overlying the erosional surface incising the Mio-pliocene pre-estuarine deposits there follows a succession of fluvio-marine deposits (ca. 9000 calBP), an open estuarine facies with central basin muds and sandy tidal delta interbeds, with a maximum ca. 6.500 calBP, and a transition to tidal flat deposits after ca. 2800 calBP. Two episodes of extreme wave energy at ca. 3000 calBP and ca. 195 calBP were identified and interpreted as tsunami surges, the latter ascribed to the catastrophic Lisbon earthquake and the related tsunami.

For that purpose, the alluvial archives adjacent to the Montelirio tholos site (Santiponce-Seville sector) have been studied, with special emphasis on the analysis of climatic, hydro-geomorphological, anthropic and eustatic factors recorded during the second half of the Holocene close the mouth of the Guadalquivir. Results allow to establish the existence of four large phases characterized by a predominance of alluvial sedimentation (4833-3206 cal BP; 3130-1989 cal BP, 1620 cal BP-XI century AD, and last 500 years), separated by as many episodes of stability favorable to the development of alluvial soils. From the Palaeoenvironmental point of view, it is concluded that only the first of these alluvial phases, (between the Chalcolithic and the Bronze Age), can be unequivocally associated with arid and cold conditions, assuming that these climatic features could be the most adequate for a higher incidence of floods and the accumulation of sediments. However, the strong anthropic impact recorded in this period in the Guadalquivir valley suggests that part of this aridity conditions and this tendency towards sedimentary accumulation also has to do with the human impact on vegetation cover and soils.

Firstly, we analyse the main geologic features (lithology, petrography, structures...) of the 42 capstones that cover its long corridor (over 36 m in length and an average width of 1.8 m); among these rocks, 29 of them are sandstones (67.4%), 10 are grey or green shale (23.2%) and three are granite (6.9%). Secondly, we locate potential source areas of these materials, concluding that both granites and shales, either grays or green, come from palaeozoic outcrops located on the southern edge of the Iberian Massif (Sierra Morena, around Gerena-Aznalcóllar, Sevilla), while sandstones, most likely, came from of the outcrops of Mio-Pliocene facies of the El Aljarafe marine sequence.

The data obtained confirm its usefulness in geoarchaeological studies and support the results of the archaeological researchs. Physical chemistry parameters such as organic carbon, organic matter calcination, hygroscopic humidity, electrical conductivity (salinity), texture, as well as the total chemical elements analysis are identified as the most useful for the geoarchaeological interpretation of the profile.

(2000) to evidence the intensity of human activity on the Earth's surface has been evaluated for years by the Anthropocene Working Group (AWG). Recently it has been constituted as a new unit, after the Holocene, within the International Chronostratigraphic Table. Human-induced climate change and its ability to affect the global functioning of the planet today are two indicators that justify reasonably the establishment of that new epoch. Anthropisation, the current scenario of climate change and the consequences that arise from the point of view of the security of states and people are currently important subject of discussion taht attract scientifics'attention.

From a geoarchaeological approache, the historical landscapes of the floodplains of Santiponce (Italica), Seville (Hispalis) and Coria del Río (Caura) are reinterpreted.
