EgeUn###, Environmentally transformative human use of land accelerated with the emergence of agriculture, but the extent, trajectory, and implications of these early changes are not well understood. An empirical global assessment of land use from 10,000 years before the present (yr B.P.) to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers, and pastoralists by 3000 years ago, considerably earlier than the dates in the land-use reconstructions commonly used by Earth scientists. Synthesis of knowledge contributed by more than 250 archaeologists highlighted gaps in archaeological expertise and data quality, which peaked for 2000 yr B.P. and in traditionally studied and wealthier regions. Archaeological reconstruction of global land-use history illuminates the deep roots of Earth's transformation and challenges the emerging Anthropocene paradigm that large-scale anthropogenic global environmental change is mostly a recent phenomenon., National Science FoundationNational Science Foundation (NSF) [CNS 1125210], This material is based upon work supported by the National Science Foundation under grant no.

Pollen, non-pollen palynomorphs and charcoal from a colluvial soil surrounded by prehistoric petroglyphs (Campo Lameiro, NW Spain) were studied in order to assess the nature of human activities and their impact on Holocene vegetation patterns. Several phases of anthropogenic impact were observed. (i) Between 7.6 and 6.5 ka cal BP, synanthropic taxa (Urtica dioica type, Plantago lanceolata type) and coprophilous fungi (e.g. Sporormiella-type) are indicative of early (pre-agricultural) creation of small patches of pasture using fire, possibly for incipient animal husbandry or as part of a deliberate strategy to improve game availability. Such activities only had a minor effect on the deciduous Quercus-dominated forest established earlier during the Holocene Thermal Maximum. (ii) Between 5.9 and 4.8 ka cal BP a more intense signal indicative of pastoral activity was detected, corresponding to the Neolithic period. (iii) Between 4.8 and 3.4 ka cal BP, which fits within the hypothetical timeframe of petroglyph creation, the synanthropic and humidity (e.g. Cyperaceae, Mougeotia) indicators diminished while charcoal concentration increased, which can be explained by Mid-Holocene cooling/drying (Neoglaciation) in combination with reduced human impact, or by non-pastoral activities in the area possibly in association with the development of the rock art culture, converting pasture to protected open ground through anthropogenic fires. (iv) During the Late Bronze Age and Early Iron Age (3.4–2.5 ka cal BP), grazing pressure and fire regime intensity are high, coinciding with evidence of regional forest regression, despite an amelioration in climate. (v) Later phases, not corresponding to prehistoric rock art contexts, include a phase of heavy grazing and reduced fire frequency (from ca. 2.5 to 1.2 ka cal BP) as well as the near complete elimination of the deciduous woodland, the expansion of ericaceous shrubland and the evidence of local agriculture and afforestation. These results are consistent with earlier studies in the area and highlight the spatial heterogeneity in the vegetation especially during periods of prehistoric anthropogenic interference., This research was supported financially by the Spanish Ministry of Science and Education under the framework of the CONSOLIDER-INGENIO 2010 program “Programa de Investigación en Tecnologías para la conservación y valorización del Patrimonio Cultural (TCP)” (CSD2007-00058) and by “Paleopaisaje y prehistoria del Futuro Parque de Arte Rupestre de Campo Lameiro, Pontevedra” (PGIDT02CCP60601).

In recent years, the notion of landscape learning has been the object of increasing attention when discussing the neolithization of Europe. The landscape learning model stresses the necessity of gathering environmental information about a previously unfamiliar region. Therefore, it is particularly relevant in cases where the beginning of a farming economy is better explained in relation to the movements of peoples (colonization), rather than to the adoption of crops and livestock by pre-existing hunters and gatherers (acculturation). Unlike other Iberian regions, where the adoption of agriculture runs parallel to that of animal husbandry, the available data on the neolithization process of the Sierra de Gredos mountain range seem to suggest that raising livestock may have preceded plant cultivation. Based on an interdisciplinary and multi-proxy approach, this paper explores the idea that the adoption of a food-producing economy in the Amblés Valley (Ávila, Central Iberia) may have been connected with pastoralism. In this context, landscape learning provides a model for analyzing how Early Neolithic herders in their seasonal movements were capable of wayfinding by memorizing spatial features that functioned as visual landmarks.

Recent archaeological excavations (2016–2019) in the city of Tamuda (northern Morocco) yielded evidence of commercial milling and bread-making facilities dated to the Mauretanian period (first century BC). This article presents the results of the excavation of two Mauretanian buildings (E0 7 and E0 8) in the Eastern Quarter, in which evidence for flour milling and, indirectly, the preparation of bread were found. These buildings included four rooms used for milling (with low quern-stones of the rotary, saddle, and Pompeian types), as well as warehouses (full of amphorae) and other rooms of undetermined functions. Palynological analysis has indicated the milling of cereal, peas, and faba beans, while soil micromorphology revealed the roasting of hazelnuts and raised the possibility of using fish bones for the production of fish flour. Especially relevant was the discovery of a circular clay mold decorated with a heroic fishing scene, used for the decoration of bread and pies. These elements demonstrate the chaîne opératoire of bread-making—milling, dough production and decoration, and other food processing activities. This is the first time that archaeometric techniques are applied to study milling facilities in Morocco, and it is the only known association of bread stamps and pre-Roman milling facilities in North Africa., This article is the outcome of the agreement signed by the Direction du Patrimoine of the Moroccan Ministry of Culture and the University of Cádiz.

Current knowledge of climate change effects on forest ecology and species conservation should be linked to understanding of the past-time. Abies pinsapo forests constitute a model of an endangered ecosystem, highly vulnerable to ongoing warming, whose populations have been declining for centuries, while the drivers of this local depletion trend remain poorly understood. We hypothesized that long-term disturbances, both human- and natural-induced, have shaped A. pinsapo forests, contributing to these decline processes. Until today, studies using fossil pollen record to identify past climate impacts and land-use changes on A. pinsapo populations have not been done. Here, we investigate forests’ dynamics since the late Holocene (1180 cal. AD to present) in Southern Iberian Peninsula from a fossil pollen record by comparing the results obtained with climate fluctuations and land-uses changes. The pollen sequence shows a phase of stability during the Islamic Period (~1180–1400 cal. AD; ‘Medieval Climate Anomaly’), followed by increasing degradation at Christian Period concurrent with ‘Little Ice Age’ (LIA) (ca. 1487–1530 cal. AD). The Modern Period (1530–1800 cal. AD; LIA) is linked to intensive forest management, related to the naval industry. Afterwards, a progressive reduction is recorded during the Contemporary Age period (‘Industrial Period’) until ‘Recent Warming’. In short, historical severe forest management coupled with increasing aridity since LIA appear to influence A. pinsapo forest current species composition and poor structural diversity. These disturbances might be limiting the resilience of A. pinsapo forests under a climate change scenario. A selected forest management could promote a more complex forest structure.

Este artículo está sujeto a una licencia CC BY 4.0, Este trabajo pretende analizar la construcción de los paisajes medievales en el Sur del Duero. La imagen que se ha elaborado desde los estudios centrados en el registro escrito enfatizan un incremento de la actividad agraria a partir del siglo XII, como consecuencia de la repoblación. Sin embargo, el análisis del caso de Monleras, una población situada en la comarca de la Ramajería (Salamanca) revela una situación más compleja. Mediante el estudio combinado del registro escrito, de los datos arqueológicos y de dos análisis paleopalinológicos sobre sendos bonales, se ha podido reconstruir una evolución distinta. Estos espacios evidencian una ocupación antrópica desde finales del siglo IX y en el siglo X, cuando se había producido aparentemente un cambio en los patrones de asentamiento que habían definido a los siglos posromanos. Por otro lado, se produjo una transformación con una intensificación de la cerealicultura desde comienzos del siglo XII, aprovechando las favorables condiciones medioambientales que habían generado los humedales. En la Baja Edad Media y a comienzos del periodo moderno, los humedales se fueron progresivamente secando, dando lugar a un paisaje de dehesa, que ha caracterizado tradicionalmente a esta comarca. Estos cambios fueron efectuados por la población local, sin que hubiera una injerencia externa (señorial o del poder urbano) y posiblemente como parte de una acción colectiva. Se puede concluir el importante papel de la resiliencia de los habitantes ante los cambios sociales y medioambientales. Aunque estos datos se refieren a un caso de estudio específico, implican la necesidad de profundizar en la agencia local y en el dinamismo en los procesos de construcción de los paisajes medievales.

The Iberian Peninsula is an area of the Western Mediterranean among the most sensitive to climatic and anthropogenic change. It has formed the centre-piece of numerous palaeoenvironmental studies of mountain and valleys, covering different chronologies and historical periods. These studies, however, include no palaeoenvironmental background to the Roman military conquests of the late third to the late first centuries B.C. This paper presents palynological evidence from two Roman military camps, A Recacha and A Granda das Xarras, in the mountains of Northwest Iberia. The main results reflect anthropic activities that shaped the landscape since at least the end of the third millennium B.C., with the presence of montane heaths and deciduous forests. During the first millennium B.C., a modest increase in anthropic activity was detected, possibly due to seasonal grazing. Throughout the Roman conquest, slightly increased signs of anthropogenic activity on the local landscape are detected, leaving a landscape which has changed little throughout the two thousand years that have since passed., This research was developed within the framework of the IVGA Project and the results are part of project LOKI (Local Economies, Imperial Economy: Western Iberia (II B.C.–II A.D.) PID2019-104297GB-I00) and ‘Cultural Landscapes in the Northern and Northwestern Iberian Peninsula: Urban, Agrarian and Mining territories’ (NyNO) (PIE CSIC 202010E147). Support from the municipal councils of Candín, Ibias and Navia de Suarna and from the regional administration on Cultural Heritage from Castilla y León, Asturias and Galicia was gratefully received. The collaboration of the CSIC research groups ‘Social Structure and Territory. Landscape Archaeology’ (EST-AP) and ‘Environmental Archaeology’ has been crucial

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo‐Arabian monsoon, marine upwelling activity and eustatic variations in the Mid‐Holocene. On the local settlement scale, this transect is based on fine stratigraphic excavations and permits the reconstruction of the site formation processes and site catchment analysis. A large number of studies have been conducted on the Ruways‐1 site, focusing on a deep stratified sequence corresponding to three millennia of occupation. These studies include on‐site climate‐environmental signal analysis, local palaeogeography and environmental reconstruction, reservoir effect studies, typo‐technological studies, palaeoeconomic strategies, anthropological studies, sclerochronological studies and, finally, site formation processes, the understanding of which makes it possible to explain the potential and limits of the archaeological excavation. The first results confirm the richness of these archaeological archives for documenting the socio‐environmental dynamics, but also the richness of its complex sedimentary structure and the importance of conducting fine and multidisciplinary excavations to answer questions about the rhythms and functions of occupations and the causalities of socio‐environmental changes., Agence Nationale de la Recherche, Grant/Award Number: ANR‐16‐CE03‐00007; French National Research Agency; Ministère de la Culture et de la Communication

The climatic and environmental history of the SW Iberian Peninsula is explored tofill in the gap ofcontinental palaeoclimate data by a high-resolution study of Lake Medina sediments from core Co1313. Amulti-proxy approach comprising sedimentary facies analysis, elemental geochemistry, mineralogy,palynology and micropaleontology was employed to reconstruct the complex limnological response toclimate change and catchment dynamics since the early Holocene. The further definition of abruptclimate change events was supported by a robust age model and rapid sediment accumulation rate at thestudy site. Proxies indicate arid and warm climate conditions during the Early Holocene, from around 9.5to 7.8 cal ka BP, with a desiccation event at 8.8 cal ka BP as well as tentative evidence for the regionalexpression of a cold and abrupt arid climate event centering on ca. 8.2 cal ka BP. The Holocene ClimateOptimum, from around 7.8 to 5.5 cal ka BP, is characterized by a humid climate and maximum lake level.Anoxic bottom water conditions are indicated by the preservation of sediment laminae and the occur-rences of Sulfur mottles, which were observed for thefirst time within Holocene sediments of salinelakes. Mid-to Late Holocene times are governed by the 4.2 cal ka BP dry event as well as progressivearidification accompanied by the development of typical Mediterranean low-land vegetation. Duringrecent times, further progressive loss in precipitation as well asfluctuating but overall increasinganthropogenic influence on Lake Medina sediments is observed

A new record from a long sediment core (S3) in Navamuño (1505 m asl, western Iberian Central System) provides the reconstruction of the vegetation history and environmental changes in the region between 15.6 and 10.6 ka cal BP, namely during the Late Glacial and the early Holocene, using a multiproxy analysis (pollen-based vegetation and climate reconstruction, sedimentary macrocharcoals, loss-on-ignition, magnetic susceptibility and X-ray fluorescence (XRF) measurements). The results are then compared with other sequences from the Iberian Central System and the whole Iberian Peninsula in order to better understand the past dynamics of the main forest constituents. The pollen record shows a shift from open pine forests ∼15.6–14.7 ka cal BP (Oldest Dryas) to mixed open pine-birch woodlands ∼14.7–14.0 ka cal BP (Bølling). Woodlands were succeeded by a steppe-like landscape until ∼13.4 ka cal BP (Older Dryas), which was replaced again by high-mountain pine forests and riparian woodlands ∼13.4–12.6 ka cal BP (Allerød). A great development of cold steppe grasslands linked to the decline of birch woodlands is documented ∼12.6–11.7 ka cal BP (Younger Dryas). The early Holocene (11.7–10.6 ka cal BP) was characterized by a progressive reforestation of the study area by pine and birch forests in the highlands and oak woods in the lowlands. Temperate tree taxa (Carpinus betulus, Castanea sativa, Corylus avellana, Fraxinus, Juglans, Tilia, and Ulmus) were also common but likely at lower elevations. Pollen of Fagus sylvatica was already recorded during the Late Glacial and the early Holocene. The marked increasing local fire activity during the warmer and wetter Allerød oscillation could be related to a rise in tree cover, supporting the climatically driven character of these fires. Nevertheless, the strong increase in fire activity during the Younger Dryas would probably be related to growing tree and shrub mortality, as well as to the wet/dry biphasic structure of this stadial. The standard “Modern Analogue Technique” has been also applied to the Navamuño sequence to provide quantitative climate estimations for the Late Glacial and the early Holocene periods. This record is one of the few continental archives that show the climatic trend between the Late Glacial and the early Holocene in central Iberia, agreeing with many other regional records from the Western Mediterranean.

The aim of this work is to reconstruct the periods of growth and decline of human populations in Morocco and their potential impacts on the landscapeover the past 10,000 years. In order to estimate the trends in the human population size between 10,000 and 3000 years ago, we used a summedprobability distribution (SPD) of radiocarbon dates from a wide range of archaeological sites throughout Morocco. Landscape changes were identified andquantified from a dataset of fossil pollen records. Different anthropogenic pollen markers, as well as natural vegetation groups and taxonomic richnesswere used to analyse the relationship between long-term trends in human population expansion or regression and type of impact on the landscape. Thesub-regions of Morocco have different topographies and climates, which have either favoured or prevented the establishment and/or spread of humanpopulations. In order to identify the areas most significantly impacted by humans and the timing of such impacts, we have reconstructed and compared the same past anthropogenic and landscape proxies along with the population trends within the lowlands and mountainous areas. The lowlands were morestrongly impacted earlier in the Holocene than the mountainous areas. Anthropogenic markers indicate that farming expanded in the lowlands duringthe first major expansion of human populations between ca. 7200 and 6700 cal. yr BP at the start of the Neolithic period. In the Atlas and Rif Mountains,anthropogenic impact is not clearly detectable in any of these areas before 4000 cal. BP.

Knowledge of the current status of Fagus sylvatica in the Western Pyrenean Region (Northern Iberian Peninsula) is based on its widespread presence in mountain areas. However, the past evolution of this taxon and its links to natural and anthropogenic activities is not well defined. We have compiled all the published palaeobotanical data (macro and micro remains) on this region, including both natural and archaeological deposits and with particular emphasis on available radiocarbon dates. To support our analysis of the evolution of F. sylvatica, we present the palynological study of a new sequence (Gesaleta, Navarre), covering the last 11,400 cal yr BP. The main results of this paper suggest the ancient presence of F. sylvatica in the Western Pyrenean Region from at least the Late Pleistocene and Early and Middle Holocene, with a clear expansion from ca 4,500–3,500 cal yr BP, although with some regional differences. This was the point when European beech became one of the main actors in mountain forests, where it has been exploited for a variety of anthropogenic activities, Mónica Ruiz-Alonso and Sebastián Pérez-Díaz are funded by the Programa Estatal de Promoción del Talento y su Empleabilidad en I + D + i (Juan de la Cierva).

Agrarian landscapes are among the least understood features of first millennium B.C. societies in the western Mediterranean. Studies of such landscapes in the context of the Iberian Iron Age have been based essentially on the archeological record in places used for purposes other than farming, particularly settlements and areas reserved for burials and rituals, or on the identification of the possible use of fertilizers. Here we present a multiproxy analysis of an agrarian landscape based on geoarchaeological and paleoenvironmental studies in a mountainous region in southeastern Iberia. The findings confirmed the existence of farmland cultivated as early as the first millennium B.C. in the high Jutia Valley in the Spanish province of Albacete. These results suggest that coordinated analyses can be highly useful for identifying enduring agricultural practices, while contributing to a fuller understanding of western Mediterranean agrarian landscapes and their millenarian resilience, attributable to the coevolution of human communities and the environment

This paper presents the archaeobotanical and archaeozoological data of the 6th to 4th millennia cal BC sequence recently documented at Dehesilla Cave, and puts forward an interdisciplinary approach to the significant ecological patterns from this key archaeological site in the Southern Iberian Peninsula throughout the entire Neolithic period. Results indicate an ecological scenario characterised mainly by oak and wild olive forests, and human populations with agricultural practices and herds of mainly sheep and goats. However, this general panorama must have undergone several remarkable fluctuations. The first Neolithic populations of Dehesilla Cave, dated around the mid-6th millennium cal BC and linked to the Mediterranean impressa pottery complex, do not yet display evidences of agriculture, while all of the subsequent Early Neolithic levels indicate a model of small-scale populations with a mixed economy but still with a greater component of livestock. The second quarter of the 5th millennium cal BC shows a marked accentuation of the monoculture of naked wheats, which could have been related to the transition from an intensive to an extensive farming system. This may have entailed a selective pressure on the environment, leading to a large deforestation spanning the second half of the 5th millennium cal BC and the constitution of relatively open thermo-Mediterranean forests with a physiognomy similar to that of the dehesa. These ecological patterns are discussed within a review of the current state of the art of the use of plant and animal resources by the Neolithic human populations in the southern regions of the Iberian Peninsula.

Lake Medina is a small, shallow and endorheic salt lake sensitive to climate variation in south-western Spain, close to Cádiz in western Andalusia. It is located in an evaporitic and karstic environment, and a saline lake affected by highly seasonal precipitation and evaporation. Geochemical and mineralogical data of core CO1313 combined with a robust age model show variation that contributes to the understanding of palaeoenvironmental and palaeoclimatic change. This study shows a pollen record that has been conducted on core CO1313, together with charcoal and non-pollen palynomorph analyses. The environmental and climatological history reconstruction of Lake Medina starts in early Holocene times (at 9.5 cal. ka BP) and shows intensified pasture and land use during middle-Holocene times as well as the 8.2 and 4.2 cal. ka BP abrupt climate events. Oxidation of plant remnants and resulting non-preservation at certain times reinforces the hypothesis of intense climate effects on vegetation during the 4.2 cal. ka BP climate event. Yet, oxidation of plant residues during other episodes shows other periods that were also affected by reduced precipitation. From around 2 cal. ka BP onwards, a recent trend towards aridification and enforced seasonality was detected.

Cedrus atlantica (Atlas cedar) is a relict and endemic endangered species from northwestern African mountains, whose distribution range has undergone a dramatic reduction over recent decades. Long-term studies are needed for a better understanding of the development of its range as well as for assisting in the implementation of sustainable conservation measures. The multi-proxy analysis of a high-resolution fossil record of 180 cm depth allowed us to depict the final demise of an Atlas cedar population from the western Rif Mountains (Jbel Khesana), despite its high resilience during the last ~4000 years. Currently, Atlas cedar trees are not observed in Jbel Khesana but they still occur in the nearby area as scattered populations on a few mountain tops at altitudes higher than 1400 m a.s.l. Our data show an initial relatively stable period (~4000¿2400 cal. yr BP) followed by a phase where both climatic and human-induced disturbances cause an alternate dominance of oaks and Atlas cedars (2400~1550 cal. yr BP). Then, the increasing aridity and human activities favoured the depletion of Atlas cedar forests (~1550¿800 cal. yr BP). Our record shows that Atlas cedar forests have recovered after each deforestation event, which reveals a high resilience of the species until the mid-20th century, when they became extinct in the study area. The main driver of their local extinction may be attributed to the strong human pressure. Management measures of Atlas cedar in the Rif Mountains should aim at limiting intensive loggings and protecting the existing populations for their local regeneration.

[EN] The study of the Neolithic in the Levant of the Iberian Peninsula has a long research trajectory, being well known in some river valleys such as Serpis or Clariano. The excavation of a large number of cave and open-air deposits has made this area an outstanding reference on a peninsular scale and in the western Mediterranean. However, other nearby river basins such as the Vinalopó basin have not yet had sufficient sequential bases for their characterization. The first proposals, established from the material remains found in various open-air sites and in caves, had led to consider that the process of neolithization would begin at the end of the sixth millennium cal BC, almost half a century after the presence of agricultural communities along the Serpis river. The process of Neolithic implantation in the Vinalopó had to be explained, therefore, as a result of the population expansion from the Serpis. However, new excavations and studies come to expand the range of possible explanations. Regarding the archaeological evidence documented during the excavations at Cova dels Calderons (La Romana, Alicante), we present new data, especially sedimentological, paleobotanical, archeozoological and new absolute dates. These allow us to reflect on the neolithization process of the territories in the Southern Valencian region, specifically in the Vinalopó river basin. These data make possible to formulate a new hypothesis which considers that the presence of Neolithic groups in that territory would occur much earlier than it was considered to date. This hypothesis leads us to two new possible scenarios: either the arrival of the first Neolithic groups to the northern areas of Alicante occurred in earlier times, or the origin of the first Neolithic populations in the southern areas of Alicante is not what it has been thought to date –northern basins such as the Serpis river one–. Considering this, the southern route to access these areas seems the most possible option., [ES] El estudio del Neolítico en el Levante de la península Ibérica cuenta con una larga trayectoria investigadora, siendo bien conocido en algunos valles como el Serpis o el Clariano. La excavación de un buen número de yacimientos en cueva y al aire libre ha posibilitado que esta zona sea un referente destacado a escala peninsular y del Mediterráneo occidental. Sin embargo, otras cuencas fluviales muy cercanas como la del río Vinalopó no han contado hasta el momento con suficientes bases secuenciales para su caracterización. Las primeras propuestas, establecidas a partir de los restos materiales hallados en diversos yacimientos al aire libre y en cueva, habían llevado a considerar que el proceso de neolitización se iniciaría a finales del VI milenio cal BC, casi medio siglo después de la presencia de comunidades agrícolas a lo largo del río Serpis. El proceso de implantación neolítica en el Vinalopó debía explicarse, por tanto, como resultado de la expansión poblacional desde el Serpis. Sin embargo, nuevas excavaciones y estudios vienen a ampliar el abanico de posibles explicaciones. Así, a propósito de las evidencias arqueológicas documentadas en la excavación de la Cova dels Calderons (La Romana, Alicante), se exponen nuevos datos sobre la ocupación neolítica, en especial sedimentológicos, paleobotánicos, arqueozoológicos y nuevas dataciones absolutas, que permiten reflexionar sobre el proceso de neolitización de las tierras meridionales valencianas y, más en concreto, de la cuenca del río Vinalopó. Ello permite configurar una nueva hipótesis que viene a considerar que la presencia de grupos neolíticos en dicho territorio es más antigua que lo planteado hasta la fecha. Esta hipótesis, a su vez, lleva a inferir dos nuevos escenarios posibles: o bien, que el momento de llegada de los primeros grupos neolíticos a las tierras del norte de Alicante fue más antiguo de lo propuesto, o bien que la procedencia planteada para las primeras poblaciones neolíticas del sur de Alicante no sea la hasta ahora considerada –origen en cuencas más septentrionales como la del Serpis–, siendo la vía sur la más probable., [EU]Iberiar penintsulako Levante aldean Neolitikoaren azterketak ibilbide luzea du ikerketari dagokionez, eta oso ezagunak dira haran batzuk, hala nola Serpis edo Clariano. Leizean eta aire zabalean aztarnategi kopuru handia induskatu direnez, eremu hori erreferente nabarmena da penintsula mailan eta mendebaldeko Mediterraneoan. Hala ere, oso gertu dauden beste ibai-arro batzuetan, Vinalopó ibaian, esaterako, ez dira orain arte karakterizatu ahal izateko nahikoa oinarri sekuentzial bildu. Aire zabalean eta leizean dauden aztarnategi ugaritan topatutako hondakin material ugaritatik abiatuta egindako lehen proposamenen arabera, uste izan da neolitizazio-prozesua cal BC VI milurte amaieran hasiko zela, Serpis ibaian zehar nekazaritzako komunitateen presentzia baino ia mende erdi geroago. Vinalopóko ezarpen neolitikoaren prozesua, beraz, Serpisetik populazioa zabaldu izanaren ondorioa dela uste da. Baina egindako indusketa eta azterketa berriek azalpen posibleak ugaritu dituzte. Hala, Cova dels Calderons-eko (La Romana, Alacant) indusketan dokumentatutako ebidentzia arkeologikoak direla eta, okupazio neolitikoaren inguruan datu eta datazio absolutu berriak agertu dira, bereziki sedimentologikoak, paleobotanikoak eta arkeozoologikoak. Horrek guztiak Valentziako hegoaldeko lurretako, eta zehatzago, Vinalopó ibai-arroko neolitizazio-prozesuari buruz hausnartzea ahalbidetzen du. Hala, hipotesi berri bat eragin du: lurralde horretan talde neolitikoen presentzia izan zitekeen orain arte planteatutako data baino lehenagotik. Hipotesi horrek, era berean, bi egoera posible berri dakartza: alde batetik, lehen talde neolitikoak Alacant iparraldera proposatutako data baino lehen iritsi izana, edo beste alde batetik, Alacant hegoaldeko lehen populazio neolitikoetarako planteatutako jatorria ez izatea orain arte kontuan hartutakoa (iparralderago dauden lekuetatik etorri izana, adibidez Serpisetik), eta hegoaldeko bidea izatea probableena.

The study of anthropogenic activities in prehistoric landscapes has increased greatly in recent decades in theNorthern Iberian Peninsula, particularly through pollen records from low altitude areas where settlement wasmore frequent throughout Prehistory. However, little is known about the evolution of landscapes in highlands,particularly in the Basque-Cantabrian mountains (Northern Iberia). In this paper, we analyze human dynamics inmountain landscapes through the multiproxy analysis of Arbarrain mire from c. 8200 cal BP. Obtained mainresults show the predominance of deciduous forests in the whole sequence, with presence of pinewoods at aregional scale. Thefirst evidence of anthropization of mountain environments is dated c. 6800 cal BP, in relationwith the early Neolithic. During the Mid-late Neolithic evidences of human impact on the landscape increases inparallel to the development of the megalithic structures. The Chalcolithic shows a decrease in the anthropogenicactivities in mountains. Finally, during the Bronze Age, Iron Age and Historical Period, from c. 4000 cal BP,mountain ecosystems reflect the expansion ofFagus, clearly linked with a further increase in human activity,origin of current landscape configuration.

This paper presents the first comprehensive pan-Iberian overview of one of the major episodes of cultural change in later prehistoric Iberia, the Copper to Bronze Age transition (c. 2400–1900 BC), and assesses its relationship to the 4.2 ky BP climatic event. It synthesizes available cultural, demographic and palaeoenvironmental evidence by region between 3300 and 1500 BC. Important variation can be discerned through this comparison. The demographic signatures of some regions, such as the Meseta and the southwest, diminished in the Early Bronze Age, while other regions, such as the southeast, display clear growth in human activities; the Atlantic areas in northern Iberia barely experienced any changes. This paper opens the door to climatic fluctuations and inter-regional demic movements within the Peninsula as plausible contributing drivers of particular historical dynamics.

This paper describes the patterns and processes of vegetation change and fire history in the Late Holocene (c. 3,140 cal BP) palaeoecological sequence of El Tiemblo, in a mountainous area in central Spain (Gredos range, Spanish Central System), and provides the first Iberian pollen sequence undertaken within a Castanea sativadominated woodland. These new data reassess not only the autochthonous nature of the species in the region and in the Iberian Peninsula, but also the naturalness of well-developed sweet chestnut forests. The study focuses on anthropogenic dynamics linked both to the effects of livestock husbandry and the use of fire for forest clearance. With this aim, non-pollen palynomorphs (coprophilous fungi ascospores) and charcoal accumulation rate are useful indicators for assessing the increasing role of human influence on vegetation, We sincerely thank three anonymous reviewers and the editor for their constructive suggestions and comments.

Little is known about the impact of human activities during Roman times on NW Iberian mining landscapes beyond the geomorphological transformations brought about by the use of hydraulic power for gold extraction. We present the high-resolution pollen record of La Molina mire, located in an area intensely used for gold mining (Asturias, NW Spain), combined with other proxy data from the same peat core to identify different human activities, evaluate the strategies followed for the management of the resources and describe the landscape response to human disturbances. We reconstructed the timing and synchronicity of landscape changes of varying intensity and form occurred before, during and after Roman times. An open landscape was prevalent during the local Late Iron Age, a period of relatively environmental stability. During the Early Roman Empire more significant vegetation shifts took place, reflected by changes in both forest (Corylus and Quercus) and heathland cover, as mining/metallurgy peaked and grazing and cultivation increased. In the Late Roman Empire, the influence of mining/metallurgy on landscape change started to disappear. This decoupling was further consolidated in the Germanic period (i.e., Visigothic and Sueve domination of the region), with a sharp decrease in mining/metallurgy but continued grazing. Although human impact was intense in some periods, mostly during the Early Roman Empire, forest regeneration occurred afterwards: clearances were local and short-lived. However, the Roman mining landscape turned into an agrarian one at the onset of the Middle Ages, characterized by a profound deforestation at a regional level due to a myriad of human activities that resulted in an irreversible openness of the landscape., This work was funded by the projects HAR2008-06477-C03-03/HIST, CGL2010-20672 (Plan Nacional I+D+i, Spanish Ministry of Science and Innovation), 10PXIB200182PR (General Directorate of I+D, Xunta de Galicia), and CDS-TCP (CSD2007-00058, Programa Consolider-Ingenio 2010)

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic-Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/. dicoccum, Triticum durum and Triticum aestivum/. durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry. © 2013 Elsevier Ltd., The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP7/2007–2013)/ERC Grant Agreement n° 230561.

Palynological analyses were carried out on layers from the site of La Vereda in Burguillos (Sevilla), in southern Spain. The layers dated to the 3rd century AD, around the time of the abandonment of the present excavated area. Data from pollen and non-pollen palynomorphs contributed to add details on the function of the site and their structures. During Roman times, cereals, flax and olive were cultivated, and human activities highly influenced the landscape., Análisis arqueopalinológicos se llevaron a cabo en contextos del yacimiento de La Vereda (Burguillos, Sevilla), en el sur de España, ubicados cronológicamente en el siglo III d.C. en el momento de abandono hasta la actualidad del área excavada. Los datos aportados por el estudio de pólenes y microfósiles no polínicos contribuyen notablemente a detallar la función de determinadas estructuras documentadas en el sitio. En época romana se cultivaron cereales, lino y olivos, en un paisaje muy alterado por las actividades antrópicas, El trabajo palinológico ha sido financiado por el Proyecto de investigación de Excelencia P11RNM-7033 de la Junta de Andalucía; y la parte arqueológica por el proyecto HAR2013-43599P y HAR2016-78691P del MINECO

Following palaeobotanical, sedimentological and archaeological research recently conducted on and around the tell of Dikili Tash (Eastern Macedonia, Greece), we present continuous palaeoenvironmental data on this multiperiod site. This study combines pollen, non-pollen palynomorphs (NPPs), macro-charcoal and sedimentological analyses that are compared with archaeological data from the Middle Neolithic to Antiquity period. It provides an overview of the local environment near the former Tenaghi-Philippon marsh and a comprehensive view of human impact on vegetation cover in lowlands. As early as ca. 4550 cal BCE, an initial phase of change in vegetation cover, has been recorded. This period, in the Eastern Mediterranean region, is one of intensifying human activities and social interactions into the Balkan region, which resulting in the foundation and transformation of early Late Neolithic societies. Although the palynological record does not show the crops species grown, the intensive clearance resulted in the increase of open herbaceous landscapes with anthropogenic indicators. This, as well as the increase of macro-charcoal values strongly supports a more or less continuously shaping of the landscape by human induced fires. New tree species that also became established at this time include Olea and Castanea. The presence of three main formations can be argued from the Early Neolithic to Antiquity: (1) riparian vegetation, (2) oak woodlands and (3) open vegetation in the form of wooded grasslands. Beyond the responses to climate changes, the vegetation composition reflects a regionally diversified land management system as indicated by a greater diversity in cultivated or harvested plants. The study reveals two phases of decline in land use directly on the edge of the marsh, although indicators of anthropogenic disturbance of the vegetation never entirely disappear during these periods between 3900 and 3300 cal BCE at the transition from the Late Neolithic (LNII) to the Bronze Age and from 1650 to 800 cal BCE when we observe a reorganization of the settlement on the higher slopes. In contrast, four periods are characterized by an increase in land use extension and intensification: Late Neolithic (4500–3900 cal BC); Early to Middle Bronze Age (3000–1600 cal BCE), the Iron Age (1000–800 cal BCE) and Antiquity during the Macedonian (ca. 357–148 cal BCE) and Roman periods (148 cal BCE–cal 395 CE), This study is part of the framework of the international PaleoMexINEE Research Program, itself a component of the Mediterranean Integrated Studies at Regional and Local Scales [MISTRALS] support by the INEE and INSU of the CNRS.

12 páginas, 5 figuras., [ES] Se presentan los resultados de una caracterización palinológica realizada en un perfil en el cual se ha identificado una probable estructura de cultivo artificial (terraza) de finales de la Edad del Hierro, asociada a un castro en Galicia. El análisis combinado de las evidencias estratigráficas y palinológicas permite proponer una secuencia de transformación del paisaje en la que, de forma poco esperable, la mayor intensificación en el uso de la zona, correspondiente a la ocupación del castro y el desarrollo de estructuras agrarias, coincide con un episodio de incremento de los espacios forestales en el entorno. Sin embargo, el análisis realizado permite documentar la progresiva construcción de un paisaje cada vez más antropizado y donde los efectos de la acción humana se van haciendo más visibles., [EN] A series of samples extracted from the stratigraphic profile of a possible cultivation terrace located in the surroundings of an Iron Age hillfort in Galicia were used for pollen analysis. The combined results of both the stratigraphic information and the pollen analysis allow the proposal of a sequence of landscape transformation where, rather unexpectedly, the greater intensification in the use of the area, corresponding to the occupation of the hillfort and the construction of cultivation structures, coincides with an increase in the forested areas in the environment. However, the results of the analysis also document the construction of a landscape in which the effects of human action are progressively more visible.

This paper focuses on pollen, spores, non‐pollen palynomorphs (NPPs) and certain geochemical elements from the ombrotrophic blanket bog of Zalama (Basque‐Cantabrian Mountains, northern Iberian Peninsula), with the support of a robust chronology based on 17 AMS 14C dates. The main results related to the last 8000 years show that, during the early middle Holocene, pines and deciduous forests were the most extensive tree formations. At the beginning of the succession, pines reach 44%, showing regional presence, whereas after 7600 cal. a BP, deciduous forests were particularly abundant. From c. 6500 cal. a BP the pollen diagram constructed from our samples shows the first anthropogenic evidence, linked with the new economic practices related to the Neolithic of the Basque‐Cantabrian Mountains. From 3300 cal. a BP the expansion of Fagus sylvatica is particularly clear, and has since then become one of the dominant forest species in this region. We also discuss the Holocene evolution of other noteworthy plant communities in southwestern Europe, such as Taxus baccata, Juglans and shrublands., S.

Despite increasing interest in the relationship between culture transformation and abrupt climate change, their complexities are poorly understood. The local impact of global environmental fluctuations depends on multiple factors, and their effects on societal collapse are often assumed rather than demonstrated. One of the major changes in west European later prehistory was the Copper to Bronze Age transition, contemporaneous with the 4.2 ky cal. BP event. This article offers a multi-dimensional insight into this historical process in the Iberian Peninsula from a multi-proxy and comparative perspective. Three study areas, representative of diverse ecological settings and historical trajectories, are compared. Using radiocarbon dates, 13C discrimination (Δ13C) values on C3 plants, and high-resolution palynological records as palaeoclimatic and palaeodemographic proxies, this study tracks the uneven signals of Holocene climate. The wettest Northwest region features the most stable trend lines, whereas the Southwest exhibits an abrupt decrease in its demographic signals c. 4500 cal. BP, which is then followed by a subsequent rise in the neighbouring Southeast. These lines of evidence suggest the possibility, never previously noted, of demic migration from the Southwest to the Southeast in the Early Bronze Age as a contributing factor to the cultural dynamics of southern Iberia.

The Western Massif of the Picos de Europa (latitude 43° N, longitude 4–5° W) includes some of the highest peaks in the Cantabrian Mountains. This massif was heavily glaciated during the Last Glaciation, though the post-glacial environmental evolution is still poorly understood. Using a complementary geomorphological and sedimentological approach, we have reconstructed the environmental events occurred in this massif since the last Pleistocene glaciation. The geomorphological distribution of glacial landforms suggests the occurrence of four main glacial stages: maximum glacial advance, glacial expansion after the maximum advance, Late Glacial and Little Ice Age. Moreover, a 5.4-m long sedimentary sequence was retrieved from the karstic depression of Belbín providing a continuous record of the paleoenvironmental conditions in this area since the Last Glaciation until nowadays. This section suggests that the maximum glacial expansion occurred at a minimum age of 37.2 ka cal BP, significantly prior to the global Last Glacial Maximum. Subsequently, periglacial processes prevailed in the mid lands of the massif until glaciers expanded between 22.5 and 18.7 ka cal BP. Following the melting of the glaciers, a shallow lake appeared in the Belbín depression. Lake sediments do not show evidence of a cold stage during the Late Glacial, when moraine systems formed at higher locations. The terrestrification of this lake started at 8 ka cal BP and the area turned into grassland. At 4.9 ka cal BP the existence of charcoal particles in the sediments of Belbín sequence reveals the onset of human occupation in the massif through the use of fire activity for grazing purposes. Finally, the presence of moraines inside the highest northern cirques shows evidence of the last glacial phase that occurred during the Little Ice Age cold event. Since then, the warming climate has led to the melting of these glaciers and periglacial processes prevail in the high lands of the massif., The authors acknowledge the support provided by the Picos de Europa National Park during the fieldwork developed between 2005 and 2011.

The study of environmental change during the ‘Little Ice Age’ (‘LIA’) offers a great potential to improve our current understanding of the climate system and human–environment interactions. Here, a high-resolution multiproxy investigation of a Mediterranean mire from central-western Spain, covering the last ~700 years, was used to reconstruct peat dynamics and land-use change and to gain further insights into their relationship with ‘LIA’ climate (temperature and moisture). To accomplish this, concentrations and accumulation rates of major and minor lithogenic (Si, K, Ti, Rb and Zr) and biophilic (C and N) elements, as well as humification indices (UV-absorbance and Fourier-transform infrared spectroscopy (FTIR)) and pollen and non-pollen palynomorphs, were determined. Peatland dynamics seems to have been coupled to changes in solar irradiance and hydrological conditions. Our results point to wetter conditions after the mid-16th century, although with high intra-annual fluctuations. At the late 18th century, when solar activity was systematically higher than before, peat carbon accumulation rates (PCAR) showed a continuous increase and the humification indices suggest a change towards more humified peat. Enhanced soil erosion occurred at ~AD 1660–1800 (SE1), ~AD 1830–1920 (SE2) and ~AD 1940–1970 (SE3), although a minor increase in Si fluxes was also detected by ~AD 1460–1580. All phases coincided with higher abundances of fire indicators, but the changes recorded during the ~AD 1460–1580 event and SE1 coincide with the Spörer and Maunder minima, so a climatic influence on soil erosion cannot be discounted. Changes in the sources of mineral matter to the catchment between ~AD 1550 and ~AD 1650 and since the mid-17th century were likely related to modifications of tree cover and/or variations in wind strength., This work was funded by the projects HAR2013-43701-P (Spanish Economy and Competitiveness Ministry) and CGL2010-20672 (Spanish Ministry of Science and Innovation).

Overlying a palustrine deposit of unknown age (complex FP), and protected from weathering and erosion inside a large cave/rock-shelter cavity, the sedimentary fill of Cueva Antón, a Middle Paleolithic site in SE Spain, corresponds in most part (sub-complexes AS2-to-AS5) to a ca.3 m-thick Upper Pleistocene terrace of the River Mula. Coupled with the constraints derived from the deposit’s paleoclimatic proxies, OSL dating places the accumulation of this terrace in MIS 5a, and radiocarbon dates from the overlying breccia cum alluvium (sub-complex AS1) fall in the middle part of MIS 3; the intervening hiatus relates to valley incision and attendant erosion. The two intervals represented remain largely unknown in Iberia, where the archeology of the early-to-middle Upper Pleistocene is almost entirely derived from karst sites; Cueva Antón shows that this dearth of data, often interpreted in demographic terms, has depositional underpinnings ultimately determined by past climate variation. In early MIS 5a, the paleobotanical evidence indicates climate conditions similar to present, albeit wetter, followed by progressive cooling, reflected in the replacement of Aleppo pine by black pine and, at the very end, juniper-dominated landscapes — the latter characterizing also mid-MIS 3 times. The variation in sedimentary facies and composition of the mollusk assemblages reflects the changing position of the river channel relative to the back wall of the cave. Such changes represented the major constraint for the occupation of the site — most of the time inaccessible to terrestrial mammals, it was used throughout by the eagle-owl, explaining the abundance of rabbit bones. Human occupation occurred during a few, short windows of availability, and is reflected in well-preserved living floors defined by hearths, artefact scatters, and the remains of hunted herbivores. The stone tool assemblages are Middle Paleolithic, which, in Europe, implies a Neandertal identity for their makers and, hence, that Neandertals persisted in the region until GI 8. Cueva Antón’s high-resolution record provides unique, critical information on the paleoenvironments and adaptations of humans in two short windows of time during which wetter conditions existed in SE Iberia, where arid or semi-arid climates prevailed through most of the Upper Pleistocene and the Holocene., Archeological fieldwork and research at Cueva Antón was funded by the Dirección General del Medio Natural de la Región de Murcia, the Municipality of Mula, the University of Murcia, the Fundación Séneca (Murcia), the Ministerio de Ciencia e Innovación (grants HAR2011-24878, HAR2014-52671-P and CGL2012-34717), the Generalitat Valenciana (grant PROMETEOII/2013/016), the Excellence Research Projects Program of the Andalusian Government (grant P11-RNM-7033), and the Leakey Foundation.

Ongoing archaeological research at North Lake Eyasi has produced a wealth of information, including a new hominid fossil and several archaeological sites dating to the end of the Middle Pleistocene. One of the sites (WB9) has been excavated and has produced evidence of multiple processes in its formation, including evidence of functional associations of stone tools and faunal remains which are scarce for this time period. The stone tool industry is based on a core and flake industry, which is not very diagnostic and attributed to MSA. Earlier heavy-duty tools classified as Sangoan may derive from the underlying Eyasi Beds. The stratigraphic provenience of previous fossil hominids is unknown. Surface collections from the Eyasi lake, thus, comprise two different sets of stone tools and fossils, which can only be clearly differentiated in the field. This advises against the use of previously curated collections as a homogeneous sample. Earlier definitions of the Njarasa industry should be revised. This work presents results on the paleoecology of the area and of its paleontological and archaeological information, with special reference to the excavation of WB9, the most complete site discovered in the area so far. This contributes to the limited information available about site functionality and hominid subsistential behaviour in East Africa during the end of the Middle Pleistocene. A technological study from WB9 also shows the variability of stone tool traditions at this time.

The present study aims to review palaeoecological evidence for environmental changes induced by human activities over the last few millennia in the montane landscapes of Morocco. The study is based on well-dated pollen and geochemical records from the Rif and the Middle Atlas mountains, to show spatial and temporal variation in the onset and intensity of exploitation of forest, soil and mineral resources. Before ca. 2000 BP, anthropogenic impact was minimal. At about that time, abrupt changes of the arboreal pollen proportions, with a decline in all tree taxa, indicate a reduction of the forest cover interpreted as being anthropogenic. In the Rif Mountains, increased influx of carbonates (Ca) in the sedimentary records indicates enhanced soil erosion coincident with the reduction in tree cover. In the Middle Atlas, reduced forest cover is linked to geochemical evidence for mining and metallurgy of lead (Pb), copper (Cu) and zinc (Zn). These industrial activities correspond to the expansion of the Roman Empire into Morocco at around AD 40 and show a decline when the Romans were displaced by the Vandals about five centuries later., RC thanks Jean Maley for the friendly incitement to write the present paper.

Estudios recientes indican que las motillas, asentamientos de la Edad del Bronce de La Mancha, pudieron ser las más antiguas captaciones de agua subterránea en la Península Ibérica. Pero ¿por qué no existen motillas en el Campo de Montiel, territorio ubicado tradicionalmente en esta área cultural? En Castillejo del Bonete, sitio arqueológico situado en esa comarca, existe una cueva que fue utilizada y sellada durante la Prehistoria Reciente. Se presenta ahora la primera investigación paleohidrogeológica interdisciplinar en La Mancha, que ha analizado manantiales y niveles de agua subterránea del acuífero de Campo de Montiel, así como el interior de la sima de Castillejo del Bonete. Las conclusiones avanzan una relación entre el sustrato hidrogeomorfológico y la distribución espacial de las motillas. Además permiten descartar que la sima de Castillejo del Bonete fuera utilizada como mina o como acceso al acuífero, dos de las hipótesis de trabajo planteadas. De ese modo cobra fuerza que Castillejo del Bonete fuera un excepcional monumento funerario y simbólico durante el Calcolítico y la Edad del Bronce, perteneciente a una nueva clase de asentamientos desconocidos hasta ahora en el grupo cultural de la Edad del Bronce de La Mancha., Esta publicación ha sido autorizada por la Dirección General de Cultura de la Junta de Comunidades de Castilla-La Mancha (Exp.

Este artículo está sujeto a una licencia CC BY 4.0, Precipitation is a key climate parameter of vegetation and ecosystems in the Iberian Peninsula. Here, we use a regional pollen–climate calibration model and fossil pollen data from eight sites from the Atlantic coast to southern Spain to provide quantitative reconstructions of annual precipitation trends and excursions and their regional patterns for the last 11 700 years. The Early Holocene (11 700 to 11 000 cal. a BP) was characterized by high precipitation values followed by a slowly declining trend until about 9000 cal. a BP in the south and about 8000 cal. a BP in the north. From 8000 to 6000 cal. a BP the reconstructed precipitation values are the highest in most records, especially in those located in the Mediterranean climatic region in the southern part of the peninsula, with maximum values nearly 100% higher than the modern reconstructed values. The results suggest a declining precipitation during the Late Holocene in the south, with a positive excursion at around 2500 cal. a BP, while in the north precipitation remained high until 500 cal. a BP. However, the Late Holocene climate reconstructions in the Iberian Peninsula are biased by intensifying human impact on vegetation. The statistical time series analyses using SiZer technique do not indicate any statistically significant high-frequency drought events in the region. In general, our results suggest regional differences in the precipitation patterns between the northern and southern parts of the peninsula, with a more distinct Middle Holocene period of high humidity in the south., This research has been funded by the Academy of Finland (GRASS and HiDyn projects), by the European Research Council (project YMPACT), and through the REDISCO-HAR2017-88035-P (Plan Nacional I + D+I, Spanish Ministry of Economy and Competitiveness), RTI2018-101714-B-I00 (Spanish government), B-RNM-404-UGR18 (ERDF- Andalusian Government) and P18-RT-4963 (Andalusian Government).

This paper focus on the Holocene palaeogeography of the Ja'alan coast from the 6th to the 4th millennium cal. BC, integrating the dynamics of mangroves, lagoons, khors-estuaries and deltas, with sea-level change and the evidence from Neolithic shell middens. The distribution and maturation of mangrove ecosystems along the Arabian coasts has varied considerably, affected by physical forces such as sea-level changes, climate, tidal amplitude and duration as well as the quantity of fresh water inflow associated with the monsoon systems along the Arabian coast. Palaeo-mangroves and lagoons, today replaced by large sabkhas, appear to be correlated to mid-Holocene fossil deltas and estuaries that currently function episodically, depending on the rhythm of winter rains. All these parameters have determined and impacted the location of settlement networks and the economic strategies of the first Arabian farmers along the eastern Arabian coast. The mid-Holocene sea-level highstand stability (5th millennium BC) can be considered to be an optimum period for mangrove development and can be correlated with Neolithic sites around the mangroves. The decline of mangroves since 3000/2500 cal. BC and further degradation is mainly attributed to the prevailing arid climate that reduced summer monsoon effects in the tropical area by favouring the extension of sabkhas. We discuss these aspects based on new archaeological surveys, excavations and geoarchaeological studies.

Davis, B.A.S. et al., Modern pollen samples provide an invaluable research tool for helping to interpret the quaternary fossil pollen record, allowing investigation of the relationship between pollen as the proxy and the environmental parameters such as vegetation, land-use, and climate that the pollen proxy represents. The European Modern Pollen Database (EMPD) is a new initiative within the European Pollen Database (EPD) to establish a publicly accessible repository of modern (surface sample) pollen data. This new database will complement the EPD, which at present holds only fossil sedimentary pollen data. The EMPD is freely available online to the scientific community and currently has information on almost 5,000 pollen samples from throughout the Euro-Siberian and Mediterranean regions, contributed by over 40 individuals and research groups. Here we describe how the EMPD was constructed, the various tables and their fields, problems and errors, quality controls, and continuing efforts to improve the available data.

This study addresses the earliest strategies of permanent occupation in the mountainous regions bordering Northern Meseta in inland Iberia. This piece of work gathers together and discusses archaeological information about settlement in the Late Bronze Age and Early Iron Age and previously published high-resolution palynological cores from three study areas. Its major goal is to assess both archaeological and pollen records in order to gain a better understanding of the dynamics of occupation and transformation of these upland settings. Until cal 700 BC there are no clear signs of permanence in the highlands surrounding the Duero basin, but from that point onwards various initiatives of small-scale spontaneous colonisation have been identified. Colonisation in the Iron Age involved pastoralism, cereal agriculture and a significant use of forestry resources, causing a major anthropogenic impact with irreversible consequences. The outlined account constitutes the first synthetic overview at a macro-regional scale on the beginnings of the integrated and diversified strategies implemented in these upland regions. © Association for Environmental Archaeology 2013., The data examined in this study were partially funded by a Technology Research Consolider Programme for the evaluation and conservation of Cultural Heritage (TCP-CSD2007-00058).

We argue in this paper that Levantine rock art in the Spanish Mediterranean basin allows us to ‘map’ the economic landscape of its makers. Rock art would be the ‘monumental’ side of a dual process of landscape construction: on the one hand, rock art is the first ‘cultural’ action on the landscape beginning in the Early Neolithic; on the other hand, the first evidence of active modification of the Mediterranean vegetation comes from this period. But this evidence as well as other kinds of archaeological remains are still relatively scarce in the uplands; rock art is therefore the most complete type of evidence we can use to support an early use of the Mediterranean upland environment. We use statistical and geographical analysis, together with archaeological, ethnohistorical, and ethnographic sources and pollen data, in order to support the idea of early use and exploitation of the Mediterranean uplands since the Neolithic, and into contemporary times., This work has partially benefited from financial and technical support provided by the Spanish Consolider Program (CSD2007-00058), and the Spanish Plan Nacional de I+D+i, Ministry of Science and Innovation (projects HAR2008-06477-C03-03/HIST and CGL2011-30512-C02-01).

11 páginas, 5 figuras, 3 tablas., A multi-proxy study (pollen and NPPs, geochemical composition and radiocarbon dating), combined with principal components analysis, was applied to a core sampled in the Monte Areo mire (Asturias, N Spain), which covers the last 11,600 years cal BP. Both signals of Holocene climate change and transformations by human activities were recorded. The cooler stage of the early Holocene, the Hypsithermal and the Neoglaciation periods, were indentified but later Holocene abrupt climate changes seem not to have been recorded due to the particular evolution of the fen/mire system and the impact of human activities on the local hydrology. Evidence for human activity included a first phase of pastoralism by 7300 cal BP, and an extraordinary record of adoption and establishment of agriculture. The first evidence of cereal pollen, dated to approximately 6700 cal BP, represents one of the earliest records of agriculture in northern Spain. Contrary to previous studies which, based on assumed biogeographical limitations, proposed a late adoption of agriculture in the area, our results indicate a rapid expansion of agriculture in northern Spain from the eastern to the westernmost areas more in agreement with recent archaeobotanical investigations ([Zapata et al., 2004] and [Zapata et al., 2005]). The research also indicates that climate and human activities interplayed to determine the evolution of the studied area, and that a multi-proxy approach applied to natural archives appropriately located (in areas with evidence of past human occupation) is a productive way to obtain circumstantial evidence of early human activity., This work was funded by the projects HAR2008-06477-C03-03/ HIST (Plan Nacional I+D+i, Ministry of Science and Innovation, Spain), CDS-TCP (CSD2007-00058, Programa Consolider-Ingenio 2010) and AGRIWESTMED (ERC-Advanced Grants, proposal no 230561).

El trabajo atiende a la transformación de las pautas agropastoriles desde la colonización altoimperial y hasta la ocupación aldeana de comienzos del Medievo, siguiendo unos ejes diacrónicos que pivotan sobre la proliferación del hábitat rural, la creciente intensificación agraria y la especialización productiva., [EN] The authors propose an overview of the dynamics of settlement and land use in the region between the Central System and the territory south of the Duero River. The time span is the period between the Roman establishment and the Early Middle Ages. In order to study the settlement patterns, data from a field survey contained in the provincial inventories have been used. In addition, information from recent excavations in rural and urban sites has also been taken into account. Based on this data, a quantitative evaluation of land use in the Amblés Valley (Ávila) has been attempted. To do so, Geographical Information Systems have been applied in order to measure land exploitation. As a complement, palaeopalynological data both from peat bogs and from samples from archaeological sites have been added. The paper focuses on the agropastoral transformations that took place from the Flavian colonization up to the Early Middle Ages. The main aspects discussed following a diachronic point of view are: the spread of the rural habitat, the increasing agrarian intensification and the growing specialization of production.

Most unsuccessful palynological work is never published. As a consequence, pollen analysts waste time re-processing sterile sediments, and the available literature exhibits a uniformly positive record of success in pollen extraction. Here we report failures with Quaternary pollen analyses in the Iberian Peninsula; that is, case studies where it was not possible to extract palynomorphs for pollen counting. Both totally sterile and partially sterile sites are considered. Sites and perspectives for future studies are suggested. The majority of the failed studies are openair archaeological and palaeontological sites, caves and rockshelters, but there are prominent cases of success. Peat bogs have provided positive results, but only with sequences formed under continuous sedimentation processes in marshy environments. Lakes are often successful sites, but a multi-core strategy, following the facies change along a transect from the shore to the depositional centre, is recommended for saline lacustrine deposits, salt marshes and lagoons, especially when there is evidence of temporary desiccation. Cave and rockshelter infills should be considered case-by-case, and these sites definitely require a palyno-taphonomical approach to post-depositional processes. Indurated deposits are sometimes surprising in their high pollen concentration, but one must be prepared for sterility. Coprolites have been insufficiently exploited, and offer a great potential, especially those of Pleistocene Crocuta. This article shows that venturing into sediments assumed a priori to be ‘difficult’, like fluvial terraces, slope deposits, speleothems, cave travertines, and palaeosols, may nevertheless be successful. A summary is proposed of the various factors causing sterility, before, during and after sedimentation.

Cortés-Sánchez, Miguel et al., The impact of late Upper Pleistocene climate change in the western Mediterranean region has been mainly documented through marine records. Archaeological and geomorphological continental records now available for the coast of Málaga complement these records for the second part of the last major glacial episode and the early stages of the Holocene. This paper provides an overview of the archaeological, chronological and palaeoenvironmental data from the end of the Middle Palaeolithic period to the Epipalaeolithic. Sequences from the two major sites, Nerja and Bajondillo, indicate a mosaic-type response of ecosystems to the rapidly shifting conditions of the Last Glacial episode. Terrestrial mammals, for example, show no major variations from present-day communities. Plant remains in contrast, demonstrates the existence of localised refuge areas for species that would not otherwise have survived in the more widely prevailing climatic conditions of the time, whereas remains of fish and, secondarily, birds demonstrate the existence of communities without any present-day analogues combining Mediterranean and Boreal (i.e., northern Atlantic) taxa. From an archaeological standpoint, the major cultural shift is the onset of marine fishing, beginning in the Solutrean. This coincided with the end of the Last Glacial Maximum (LGM) episode. The faunal record also testifies to the rising importance of marine resources more generally. Although the data have not been used systematically to test the validity of the Broad Spectrum Revolution (BSR) hypothesis, the hints for it in the area seem compelling from the start of the Solutrean onwards. © 2008 Elsevier Ltd.

In the Southern Hemisphere, lacustrine sediments started to be deposited with the beginning of the deglaciation at ca 19,000 cal yr BP. At this time the region of Lake Caço was dominated by sparse and shrubby vegetation with dominance of steppic grasses in a poor sandy soil. The landscape did not present any ecological characteristics of a modern Cerrado. However single pollen grains of two Cerrado indicators, Byrsonima and Mimosa, suggest that some Cerrado species were able to survive under the prevailing arid climate, probably as small shrubs. After 15,500 cal yr BP, a sudden increase in the moisture rates is evidenced with the progressive expansion of rainforest showing successive dominance of various associations of taxa. The development of the forest stopped abruptly at the end of the Pleistocene between 12,800 and 11,000 cal yr BP, as attested by strong fires and the expansion of Poaceae. In the early Holocene an open landscape with a relatively high level of water in the lake preceded the progressive expansion of Cerrado species towards a denser forested landscape; fires are recorded from then on, resulting in the physiognomy of the Cerrado we know today. Late Pleistocene paleoenvironmental records from northern Brazil reflect the interplay between insolation forcing of two hemispheres with the local components represented by the interannual shift of the Inter Tropical Convergence Zone and the influence of seasonal equatorwards polar air incursions. © 2005 Elsevier Ltd.

The vegetation history of the Kargaly region has been reconstructed on the basis of pollen analysis of archaeological sediments and one peat bog, the only one found during some years of surveying this area. This latter, Novienky peat bog, located in the steppe transition zone, offers an interesting cultural and natural sequence. Palynological analysis reveals several palaeoecological phases from 4300 B.P. (Bronze Age) to the 18th-19th centuries A.D. (Russian period). Metallurgical activities in Kargaly caused deforestation from the Bronze Age onwards that mainly affected the distribution of birch forests in the region. The palaeoclimatic interpretation of the Novienki pollen diagram is based on the observed changes in the pollen curves of Picea (spruce), Pinus (pine), Abies (silver fir) and Betula (birch). These arboreal taxa are regarded as main climate indicators. The chronology is established on a 14C-dated pollen profile from the lowest peat layer as well as on the regional pollen sequences and archaeological stratigraphies.

[ES] La Cuenca Media del Guadiana ha sido el escenario de una intensa8cupación humana desde La etapa del Calcolítico hasta el periodo romano. Dicha ocupación se ha relacionado desde siempre con la explotación de sus fértiles vegas. Los estudios arqueobotánicos permiten corroborar esta hipótesis y ofrecer una imagen detallada y concreta del desarrollo agrícola y ganadero de estas poblaciones, así como de su capacidad para adaptarse a los cambios económicos y culturales producidos a lo largo de todo el 1 milenio BC., [EN] The Middle Valley of Guadiana has been the scene of an intense human occupation from the Chalcolithic to the Roman period. This occupation has been related from always to the operation of its fertile valleys. Archaebotanical studies allow us to corroborate this hypothes; and to offeer a detailed image and makes specific of cattle and agricultura1 deveiopment of these populations as well as for theircapacity to adapt to the economic aud cultural changes produced throughout the 1 millenium BC.

[ES] Se plantea una reflexión sobre las implicaciones sociales, culturales y cronológicas del mundo funerario al interior del Tajo. Concretamente los datos de la provincia de Toledo; analizados desde los yacimientos del dolmen de Azután y del túmulo del Castillejo, plantean la contemporaneidad de distintas versiones arquitectónicas en el megalitismo antiguo peninsular y la asociación manifiesta entre hábitats y sepulturas. Los nichos económicos, fundamentalmente dehesas cultivadas con zonas aclaradas para la siembra de cereal y para los pastos de los animales, abogan por proponer una economía mixta en un modelo de explotación campesina protagonizado por grupos que acuden de modo recurrente a los mismos lugares desde los momentos más antiguos del Neolítico hasta la Edad del Bronce., [EN] This paper offers a reflection on the social, cultural and chronological implications of the funeral World of the inland Tagus basin. In particular the data of the province of Toledo, analysed from the site of the megaliths of Azutan and the burial mound of the Castillejo, allows us to propose the contemporaneity of several architectural types in the early Megalithic culture of Iberia an the association between habitats and graves. The economic niches, mainly cultivated meadows with areas for sowing grain and pasture for animals, suggest the existence of a mixed economy in a peasant society practised by groups who returned to the same places from the earliest moments of the Neolithic to the Bronze Age.
