The Impact

Geochemical data of 10Be, 14C, δ18O obtained from natural archives (tree rings, ice sheets, varves, corals) indicates that the climate during the Holocene was not stable. The cosmogenic isotope fluctuations are bound by the periodicity on solar activity and climatic changes. The sharpest and most abrupt climatic deteriorations are registered in the Early and Middle Holocene at 8200, 5800, 5400, 4300, and 2800 cal BP. These events are characterized by cold conditions. The impact of climate on human communities in steppe depressions in southern Siberia (Nazarovo, Minusinsk, and Turano-Uyuk) was noticeable. The differences of local landscape-climatic conditions in these depressions were connected with global climatic changes to determine the processes of occupation, development, and migrations of ancient societies during the Neolithic, Bronze Age, and Iron Age. The chronology of archaeological cultures was also correlated with the local and global climatic changes during the Early and Middle Holocene in southern Siberia. Here, we generalize the literature data about Holocene climatic changes and archaeological cultures in the southern Siberia region.

History Of

This paper describes the morphology of a small piece of the Chalk escarpment near Brook in east Kent, and reconstructs its history since the end of the Last Glaciation. The escarpment contains a number of steep-sided valleys, or coombes, with which are associated deposits of chalk debris, filling their bottoms and extending as fans over the Gault Clay plain beyond. Here the fans overlie radiocarbon-dated marsh deposits of zone II (10 000 to 8800 B.C.) of the Late-glacial Period. The debris fans were formed and the coombes were cut very largely during the succeeding zone III (8800 to 8300 B.C.). The fans are the products of frost-shattering, probably transported by a combination of niveo-fluvial action and the release of spring waters; intercalated seams of loess also occur. The molluscs and plants preserved in the Late-glacial deposits give a fairly detailed picture of local conditions. The later history of one of the coombes, the Devil’s Kneadingtrough, is reconstructed. The springs have effected virtually no erosion and have probably always emerged more or less in their present position. In the floor of the coombe the periglacial chalk rubbles of zone III are covered by Postglacial deposits, mainly hillwashes. They are oxidized and yield no pollen, but contain rich faunas of land Mollusca, which are presented in the form of histograms revealing changing local ecological and climatic conditions. During most of the Post-glacial Period, from the end of zone III until about the beginning of zone VIII, very little accumulation took place on the coombe floor. But below the springs there are marsh deposits which span much of this interval. They yield faunas of considerable zoogeographical interest. The approximate beginning of zone VII a (Atlantic Period) is reflected by a calcareous tufa, which overlies a weathering horizon, and represents an increase in spring flow. Two clearance phases are deduced from the molluscan record. The first may have taken place at least as early as the Beaker Period (Late Neolithic/earliest Bronze Age); the second is probably of Iron Age ‘A’ date. In Iron Age times the subsoil was mobilized and a phase of rapid hillwashing began. As a result the valley floor became buried by humic chalk muds. The prime cause of this process was probably the beginning of intensive arable farming on the slopes above the coombe; a possible subsidiary factor may have been the Sub-Atlantic worsening of climate. The muds yield pottery ranging in date from Iron Age ‘Kentish first A’ ( ca . 500 to ca . 300 B.C.) to Romano-British ware of the first or second centuries A.D. Evidence is put forward for a possible climatic oscillation from dry to wet taking place at about the time of Christ. In the later stages of cultivation, possibly in the Roman Era, the valley floor was ploughed and given its present-day form.

Introduction. Recent archaeological studies deal with the integration of natural science disciplines. Such scientific interaction includes the reconstruction of climatic changes, human adaptation to the changing conditions of nature, study of sociocultural specifics in nomadic groups as well as rising archaeological cultures, with emphasis on the interconnection between the fluctuations of steppe environmental conditions and steppe populations. Analysis. The article presents the results of the carried out interdisciplinary analysis of classic and modern archaeological studies and natural science disciplines. This allows evaluating the specifics of different factors (paleoclimatic, sociocultural, etc.) influencing the “steppe-human” system in a new way. Such factors as registered climatic changes, spreading areas of archaeological cultures, mortuary funeral rites, results of paleoanthropological examination, written records and ethnographic data provide evidence to reconstructing different time-span events of early nomads’ history in one context. The reconstruction of historical reality shows quite strong correlation between the environment and specific features in the development of ancient steppe societies. Human has high adaptive abilities to changing factors. However, the steppe population mode of life is extremely conservative and it has practically never changed during the Sarmatian or Sauromatian history. Climate fluctuations over the steppe area influenced the demographic and social structure of nomadic society. During auspicious periods, nomadic communities became populous and active politically and military. If negative factors dominated, the population tended to decrease and the social structure tended to simplify. Critical indicators of aridization and humidization in Eurasian steppes are followed with the population outflow, which is evidenced by small amount of archaeological sites or even by vanishing of cultures. Results. Thus, the authors conclude that when studying archaeological sites of the Early Iron Age nomadic cultures, it is necessary to consider the steppe and human as a single organism responsive to changing and a strong impact of environmental and socio-cultural factors.

Abstract. The evolution of heathlands during the Holocene has been registered in various soil records. Paleoecological analyses of these records enable reconstruction of the changing economic and cultural management of heaths and the consequences for landscape and soils. Heaths are characteristic components of cultural landscape mosaics on sandy soils in the Netherlands. The natural habitat of heather species was moorland. At first, natural events like forest fires and storms caused small-scale forest degradation; in addition on that, the forest degradation accelerated due to cultural activities like forest grazing, wood cutting, and shifting cultivation. Heather plants invaded degraded forest soils, and heaths developed. People learned to use the heaths for economic and cultural purposes. The impact of the heath management on landscape and soils was registered in soil records of barrows, drift sand sequences, and plaggic Anthrosols. Based on pollen diagrams of such records we could reconstruct that heaths were developed and used for cattle grazing before the Bronze Age. During the late Neolithic, the Bronze Age, and Iron Age, people created the barrow landscape on the ancestral heaths. After the Iron Age, people probably continued with cattle grazing on the heaths and plaggic agriculture until the early Middle Ages. Severe forest degradation by the production of charcoal for melting iron during the Iron Age till the 6th–7th century and during the 11th–13th century for the trade of wood resulted in extensive sand drifting, a threat to the valuable heaths. The introduction of the deep, stable economy and heath sods digging in the course of the 18th century resulted in acceleration of the rise of plaggic horizons, severe heath degradation, and again extension of sand drifting. At the end of the 19th century heath lost its economic value due to the introduction of chemical fertilizers. The heaths were transformed into "new" arable fields and forests, and due to deep ploughing most soil archives were destroyed. Since AD 1980, the remaining relicts of the ancestral heaths are preserved and restored in the frame of the programs to improve the regional and national geo-biodiversity. Despite the realization of many heath restoration projects during the last decades, the area of the present heaths is just a fraction of the heath areal in AD 1900.

Tem havido a expansão do complexo sucroalcooleiro para as regiões Centro-Norte do país, devido ao aumento da demanda pelo etanol, tornando relevante a elaboração do zoneamento agroclimático para a cultura da cana-de-açúcar para essas regiões, notadamente para o estado do Tocantins. As informações climáticas e edáficas favorecem a determinação de áreas mais aptas ao cultivo e à mecanização. Por outro lado poderá ocorrer a elevação do risco climático nas regiões produtoras devido à possível influência das mudanças do clima. O presente estudo visou simular o impacto das mudanças do clima sobre o zoneamento agroclimático para a cana-de-açúcar no Tocantins, considerando os dados do modelo GFDL e cenários de emissão B1 e A1B, para o período de 2021 a 2050. Os resultados mostraram que tanto para as condições climáticas atuais, quanto para projeção do modelo, não há restrição térmica para o desenvolvimento da cultura, e que para obter boa produtividade no Estado será necessário, de forma geral, a utilização de irrigação nos períodos de deficiência hídrica. Constatou-se que, existe potencial para a produção, apesar da predominância da classe de aptidão “restrita”, e que as regiões potenciais com condições agroclimáticas favoráveis, estão localizadas no sul, sudeste e centro do Estado. As simulações dos cenários de emissões indicam fortes restrições hídricas para o Tocantins, com grande redução de áreas consideradas “aptas” e “marginais”, e aumento das áreas “restritas” ao cultivo da cana-de-açúcar. A B S T R A C T There has been an expansion trend of ethanol demand, the tendency to expansion of the complex sugarcane industry in the Center-North region requires an elaboration of agroclimatic zoning for sugarcane culture, especially in Tocantins State. The climatic and edaphic informations favor the determination of most suitable areas for cultivation and mechanization. On the other hands, it may occur an elevation of the climatic risk in the producing regions due to the possible influence of climate change. This study aimed to simulate the impact of climate change on agroclimatic zoning for sugarcane in Tocantins, considering the data generated by GFDL model and B1 and A1B emission scenarios for the period between 2021and 2050. Results showed that for both the current climatic conditions and the projected models there is no thermal restrictions for cane development and to obtain good productivity it will be necessary to irrigate the crops during the drought periods. It was found that there is potential for the production , despite the predominance of "; restricted "; aptitude class, and that the potential regions with favorable agroclimatic conditions, are located in the south, southeast and center of the State. Simulations of emissions scenarios indicate strong water restrictions to Tocantins, with great reduction in areas considered ";apt"; and ";marginal";, and increase of the ";restricted"; areas for the sugarcane cultivation.

The article offers results of preliminary archaeological investigations, conducted by Scientific Research Center «Rescue Archaeological Service» (Institute of Archaeology, National Academy of Sciences of Ukraine) in 2007 and 2017, prior to the construction project of the bypass road around Berezhany town in Ternopil region. It provides information concerning the newly discovered archeological sites as well as the elaboration of the obtainable data on formerly revealed sites in the surroundings of villages Lisnyky, Lapshyn, Hayok and Hlynovychi. According to archival and bibliographic data, archaeological surveys were previously conducted in 2006 by the expeditions of Mykhailo Filipchuk and Mykola Bandrivsky nearby villages Lapshyn and Hynovychi. However, the summaries of these surveys are insufficiently published and besides presenting the incoherent results, which cause some confusion in the number of sites. In 2007, expedition of Rescue Archaeological Service has re-examined the multi-layered settlement Hynovychi I, collecting the items from the Late Paleolithic to the Early Iron Age. Subsequent rescue archeological excavations were carried out in 2008 by the expedition led by Bohdan Salo. Ancient Rus settlement Hlynovychi III was discovered adjacent to the previous site. Around the village Lapshyn, additional archeological sites were discovered, namely Lapshyn III, IV, V, and VI, which behold several phases of the region’s inhabitants starting from the Paleolithic and until the Age of Principalities. Materials of Vysotsko and Chernyakhiv cultures are predominant on these sites. Four groups of barrows were located on the forested hills near village Lisnyky, named therefore Lisnyky I, II, III, and IV. They contain a total of 20 barrows, which could be dated to the Bronze Age. Altogether, the explorations of 2007 and 2017 has newly discovered or identified ten archaeological sites, including settlements and burrow necropolises. Seven previously known settlement were localized due to the updated information. As a result, the archeological map of the region was significantly supplemented, with the names and numbers of archaeological sites well-coordinated. Some of the ancient settlements and the barrow groups are located along the route of future bypass road, thus making it necessary to conduct preventive archaeological excavations. The results of intended studies will definitely clarify cultural and chronological identity of these sites. Key words: archeological surveys, preventive archeological studies, assessments of the impact on the archeological heritage, bypass road around Berezhany town, settlement, barrow group, Paleolithic, Bronze Age, Early Iron Age, Late Antiquity, Vysotsko culture, Chernyakhiv culture, Age of Principalities.

Since the 1990s, the Schwaz-Brixlegg mining district in the Lower Inn Valley, North Tyrol, Austria, features excavations on mostly Late Bronze (LBA) to Early Iron (EIA) Age sites, focusing on the reconstruction of metallurgic activities and of all aspects related to it. This paper reviews the Schwaz-Brixlegg archaeozoological materials and compares them with those from contemporaneous mining (copper and salt) sites on the Eastern Alps, to assess diet and subsistence strategies of the early alpine, geo-resource-centered, communities. The faunal remains from Schwaz-Brixlegg document a change in diet for the Lower Inn Valley area from the LBA to the EIA exemplified by a shift from a pig-based economy to another one based on cattle and occasionally small ruminants. These species were most often brought whole to the sites and only occasionally as meat cuts (in particular, ribs). Age and sex profiles indicate that miners consumed high-quality meat. As is also documented on prehistoric mining sites from the Eastern Alps, butchery marks evidence a standardized slaughtering process car- ried out by professional butchers. At Weißer Schrofen, pig was the main meat provider during the LBA, whereas cattle and sheep/goat were more important as dairy products and wool/skin providers. This pattern changed in the EIA, when sheep became the dominating meat supplier at the site of Bauernzeche. This shift may reflect an adaptation to climate changes, which determined the amount of fodder available for stocks, and/or to the impact of cultural and economic developments taking place during the Final Bronze Age. Variations on the faunal assemblages might also reflect agents such as topography and altitude. All in all, a logistic balance between miners (consumers) and peasants (producers) is revealed although more information is required (e.g. archaeobotany), to shed more light on the major changes recorded in the EIA. Based on gnawing marks from Weißer Schrofen, some of the dogs there must have been large-sized. Although this may constitute an exceptional case for the Bronze Age, similar results were reported from the EBA Brixlegg settlement at Mariahilfbergl. Future research is needed to elucidate the possible functional role of dogs in the context of early mining activities.

The article is devoted to the consideration of the origin and dating of celts with on the side ears, which originate from the settlements of the Late Bronze Age and transition time from the Bronze Age to the Iron Age in the Kazakh steppe and south of Western Siberia (some of which are accidental finds) and are identified by most experts to be antiquities of the Sargarinsko-Aleekseyevskaya, Begazy-Dandybayevskaya, Irmenskaya and Bolsherechenskaya cultures. Previously, such celts were dated to the beginning of the first millennium, BC. At present, there have been certain quantitative and qualitative changes. In particular, the fund of archaeological resources for the Late Bronze Age and transition time from the Bronze Age to the Iron Age had been significantly replenished, and new research concepts have appeared. This gave us the opportunity to compare the archaeological finds of the Late Bronze Age of remote regions, namely the Eastern Europe and the Kazakh steppe and south of Western Siberia. A significant similarity was revealed between the celts of the ancient cultures of the Eastern Europe and the region located east of the Urals. It is suggested that the celts with on the side ears are of Eastern Europe origin. Their appearance among the artifacts of archaeological cultures of Kazakhstan and Southern Siberia is dated to the 14th - 11/10th centuries BC.

<p>The glaciers in the Alps are currently shrinking, in some cases dramatically, due to progressive warming. At some glaciers this recession has made it possible to find tree remains and other organic material at or near the termini. At Pasterze Glacier, such findings have been made since about 1990, allowing new insights into the Holocene evolution and variability of this glacier. Initially, only relocated wood and peat boulders were collected, but around 2010 an in-situ locality became ice-free. Tree remains and other organic material from this site have mainly provided dates for a period of more than a thousand years in the middle Holocene (around 6 ka) proving a continuously smaller extent of this glacier during this period compared to today. Furthermore, a comparative interpretation of all available, some 80 radiocarbon and dendro dates suggests that Pasterze Glacier was probably at least from about 10.2 ka to about 3.5 ka continuously shorter compared to the extent around 2010 AD. For the last nearly 2800 years there is no similar evidence of comparable small glacier extents. Finally, after the early- to mid-Holocene retreat phase, a relatively delayed increase of Pasterze Glacier during the early Neoglacial (in the Alps after about 4 ka) can be deduced. Other glaciers almost reached or even exceeded the later LIA dimensions already during this period.</p><p>Moreover, Pasterze Glacier is also lagging behind the current climatic changes, i.e., its extent is not in equilibrium with the current warming. This circumstance is not only proven by the rapid recession during recent years, but also by simulations with the glacier model OGGM. The simulation results show on the one hand that Pasterze glacier has to melt back for several more kilometres to reach equilibrium with the climatic conditions of 1980-2010. On the other hand, this also documents that the recent climate conditions are already sufficient to allow a recession comparable to the early and middle Holocene stages of this glacier. Both the delayed increase in extent during the early Neoglacial and the considerably delayed current recession can be explained by the size of the glacier and the topographic conditions.</p>

AbstractThe significance of geoarchaeological investigations is indisputable in reconstructing the former environment and in studying the relationship between humans and their surroundings. Several disciplines have developed during the last few decades to give insight into earlier time periods and their climatic conditions (e.g. palynology, malacology, archaeobotany, phytology and animal osteology). Charcoal and pollen analytical studies from the rescue excavation of the MO motorway provide information about the vegetation changes of the past. These methods are used to reconstruct the environment of the former settlements and to detect the human impact and natural climatic changes. The sites examined span the periods of the Late-Copper Age, Late-Bronze Age, Middle-Iron Age, Late-Iron Age, Sarmatian period, Late Sarmatian period, Migration period, Late-Migration period and Middle Ages. The vegetation before the Copper Age is based only on pollen analytical data. Anthracological results show the overall dominance of Quercus and a great number of Ulmus, Fraxinus, Acer, Fagus, Alnus and Populus/Salix tree fossils, as well as the residues of fruit trees present in the charred wood assemblage.
