Upland agriculture and environmental risk: a new model of upland land-use based on high spatial-resolution palynological data from West Affric, NW Scotland

Marginality and climatic determinism are common themes in upland archaeology, particularly in northern Britain, but there is increasing evidence to challenge these assumptions, notably in the palynological record. An alternative model for land-use in a highland valley is developed using three high spatial-resolution pollen sequences from north-west Scotland. In spatial terms, land-use was shaped by the landscape but also structured to make the most productive use of the small, fragmented areas of better soil in a peat-dominated environment. Climate change alone provides an inadequate explanation for land-use dynamics. A combination of careful site selection, resource management, and social interactions buffered farmers from risks posed by upland conditions, whilst allowing the flexibility to respond to opportunities created by environmental and socio-economic change, particularly during the early Bronze Age, Bronze Age/Iron Age transition, Iron Age and ‘Little Ice Age’. Implications for the perception of upland farming, for the prediction of responses to environmental risk, and for the expected character and survival of archaeological evidence for past upland and mountain-farming systems are evaluated.     

Historical context and chronology of Bronze Age land enclosure on Dartmoor,UK

The upland of Dartmoor, southwest England, is one of the flagship prehistoric landscapes within Britain owing to the excellent survival of extensive prehistoric coaxial field systems. Archaeological surveys and rescue excavations during the 1970s and 1980s did much to further the understanding of this landscape; however, much remains to be explored, in particular the chronology of enclosure, the nature of the pre-enclosure landscape and the relationship between Bronze Age communities and their environment. Reconsideration of this landscape is important, given the place it holds in our understanding of subdivision of the landscape across northwest Europe during prehistory. This paper presents new palaeoecological data recovered as part of an integrated archaeological and palaeoecological project on northeast Dartmoor. The sequences detailed here include the first dated Neolithic period palaeoenvironmental data from within the prehistoric enclosed land on the moor, providing a longer-term context for enclosure. Neolithic groups are implicated in the first establishment of heathland in the study area at around 3630–3370 cal BC. During the early Bronze Age, reestablishment of hazel scrub in the study area implies reduced use of the upland, although it is not clear whether this is local or indicative of the wider landscape. A combination of pollen and fungal spore data indicates a substantial shift to species-rich grassland with grazing animals at c.1480 cal BC in a phase that lasted 400 years. The later Bronze Age and early Iron Age are characterised by low intensity use of the upland. These data provide new chronological data for land cover change on Dartmoor and whilst they broadly confirm existing models of upland land use in later prehistory, their proximity to the standing archaeology affords a more nuanced interpretation of local change.     

Response to late Bronze Age climate change of farming communities in north east Scotland

Pollen analyses are presented spanning the Bronze and Iron Ages at two sites within one river catchment in north east Scotland, one upland and one lowland site, to test the hypothesis that subsistence agricultural communities relocated their activities in response to major climatic deterioration at the end of the Bronze Age. Such responses were identified, involving the probable cessation of arable farming around the upland site and increases in the intensity of anthropogenic impacts around the lowland site. These changes are consistent with a model that posits a restructuring of agricultural activities, but are not considered indicative of settlement abandonment in the face of climatic stress.     

Bronze Age upland settlement decline in southwest England: testing the climate change hypothesis

The division of land on Dartmoor during the Bronze Age by the construction of moor-wide boundaries known as reaves represents a significant development in agricultural practice and land tenure. Previous research relating to the Dartmoor reaves suggests this way of life may have continued for no longer than 200–400 years. It has been suggested that their abandonment occurred as the result of a deteriorating climate, although there are no published palaeoclimatic reconstructions from the area. We therefore test the hypothesis that on Dartmoor, a marked climatic deterioration occurred in the late Bronze Age that can be linked to the abandonment of the reaves. A palaeoclimatic reconstruction derived from testate amoebae and peat humification analyses is presented from Tor Royal Bog, central Dartmoor, the first such record from southwest England. A major shift to a cooler and/or wetter climate is inferred from ca. 1395 to 1155 cal BC that is coincident with the period hypothesised as encompassing the abandonment. This climatic deterioration is replicated in sites in northern Britain, suggesting it was a widespread event. It is concluded that while the evidence supports a climatically forced retreat, there are a range of other socio-economic factors that must also be taken into consideration.     

A multi-proxy palaeoenvironmental investigation of the findspot of an Iron Age bog body from Oldcroghan,Co. Offaly,Ireland

In 2003, the remains of an Early Iron Age bog body, known as ‘Oldcroghan Man’, were recovered during the cutting of a drainage ditch in a bog in the Irish Midlands. Only some fingernails and a withe fragment remained undisturbed in situ in the drain face, providing the sole evidence for the original position of the body. A detailed reconstruction of the depositional context of the body has been undertaken through multi-proxy analyses of a peat monolith collected at the findspot. The palynological record shows that the surrounding area was the focus of intensive human activity during the Later Bronze Age, but was largely abandoned during the Bronze Age–Iron transition in the mid-first millennium BC. In the mid-4th century BC, a bog pool developed at the site, evidenced in the stratigraphic, plant macrofossil, testate amoebae and coleopteran records. Plant macrofossil and pollen analysis of peat samples associated with the fingernails suggests that the body was deposited in this pool most likely during the 3rd century BC. The absence of carrion beetle fauna points to complete submergence of the body within the pool. Deposition occurred shortly before or around the time that the surrounding area again became the focus of woodland clearance, as seen in the extended pollen record from the peat monolith. This period corresponds to the Early Iron Age in Ireland, during which renewed cultural connections with Britain and continental Europe can be seen in the archaeological record and widespread forest clearance is recorded in pollen records from across Ireland. The palaeoenvironmental results indicate, therefore, that the demise of Oldcroghan Man took place at a pivotal time of socio-economic and perhaps political change.     

Dynamics of pioneer colonisation in the Early Iron Age in the Duero basin (Central Iberia,Spain): Integrating archaeological and palynological records

Abstract

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.     

Characterising the late prehistoric, ‘Romano-British’ and medieval landscape, and dating the emergence of a regionally distinct agricultural system in South West Britain

Palaeoenvironmental evidence for the character of lowland cultural landscapes during the last 2500 years in Britain is poorly understood, owing to a combination of an over-reliance on data from upland sequences, and because lowland mires are typically located in positions marginal to areas of settlement and agriculture. This paper presents an attempt to derive environmental evidence for this time period from a lowland context in order to characterise the key periods of change and continuity in the lowlands. The study focuses on mid-Devon, in South West Britain, and uses small pollen sites which are embedded within the historic landscape. The South West is a particularly poor region for lowland environmental data, and has until now been reliant on upland sequences. The results show that continuity, rather than abrupt change, has characterised the landscape from the later Iron Age to the early medieval period (around cal AD 800). There is no palynologically distinct Roman period in the data, contrary to evidence from the high uplands of Exmoor that suggests a decline of the agricultural system during the immediate post-Roman period. Around cal AD 800 there is a change in the agricultural system from predominantly pastoral activities to one that led to relatively high proportions of cereal pollen appearing in the sequences, which is interpreted here as marking the onset of convertible husbandry, a regionally distinct agricultural system which is recorded from AD 1350, but whose origins are not documented. This agricultural system remained in place until the post-medieval period, when the predominant agricultural regime returned to pastoralism around AD 1750. The data clearly show discrepancies between the high uplands and the lowlands, demonstrating the potential hazards of extrapolating upland sequences to lowlands environments.     

Composing communities: Chalcolithic through Iron Age survey ceramics in the Marmara Lake basin,western Turkey

Abstract

Diachronic survey in the Marmara Lake basin of western Turkey confirms long-term settlement activity from the 5th millennium b.c. to the present. Here we present the results from a study of ceramics and settlement distribution pertaining to the Chalcolithic through the Iron Age periods (ca. 5th/4th–1st millennium b.c.). Our dataset confirms the value of a multi-pronged approach when establishing ceramic typologies from survey datasets, incorporating distribution in the landscape with macroscopic, microscopic (petrographic), and chemical (Instrumental Neutron Activation) analyses. Our results offer valuable insights into continuity as well as change of ceramic recipes in western Anatolia during the rise of urbanism in the Middle to Late Bronze Age followed by the establishment of an imperial realm in the Iron Age. From a methodological perspective, our results illustrate the value of macroscopic and chemical approaches, including principal component, distribution, density, and discriminant analyses that can be refined further by petrography, for the interpretation of surface survey ceramics.     

Prehistoric activity and environment on the North York Moors

A synoptic view and interpretation of archaeological material from the mesolithic to the end of the Iron Age is provided, and this is viewed in the context of available palaeoenvironmental information. The evidence of various settlement forms suggests that mesolithic folk occupied the region for a long period, but their environmental impact appears to have been low although not negligible. In neolithic times a probably higher population density was capable of more thorough changes of vegetation but the total permanent alteration of ecosystems is thought to be small. Evidence for settlement is entirely inferential. By contrast, the Bronze and Iron Ages were periods of considerable clearance of forest and subsequent ecological changes like the leaching of soils increased, and traces of settlement are plentiful. New data on Iron Age settlements shows a downward movement of settlement sites and some Celtic fields are noted, though they are sparse compared with other uplands in Great Britain. A number of unanswered questions are posed, mostly about the nature of the settlement pattern in mesolithic, Bronze Age and Iron Age times. No complete synthesis of archaeological and palaeoenvironmental data is yet possible at this scale but certain parts of the moors have a high potential for reconstructing prehistoric geography.     

The influence of climatic change on the Late Bronze Age Collapse and the Greek Dark Ages

Between the 13th and 11th centuries BCE, most Greek Bronze Age Palatial centers were destroyed and/or abandoned. The following centuries were typified by low population levels. Data from oxygen-isotope speleothems, stable carbon isotopes, alkenone-derived sea surface temperatures, and changes in warm-species dinocysts and formanifera in the Mediterranean indicate that the Early Iron Age was more arid than the preceding Bronze Age. A sharp increase in Northern Hemisphere temperatures preceded the collapse of Palatial centers, a sharp decrease occurred during their abandonment. Mediterranean Sea surface temperatures cooled rapidly during the Late Bronze Age, limiting freshwater flux into the atmosphere and thus reducing precipitation over land. These climatic changes could have affected Palatial centers that were dependent upon high levels of agricultural productivity. Declines in agricultural production would have made higher-density populations in Palatial centers unsustainable. The ‘Greek Dark Ages’ that followed occurred during prolonged arid conditions that lasted until the Roman Warm Period.     

When the Giant Falls: Endurance and Adaptation at Çadır Höyük in the Context of the Hittite Empire and Its Collapse

At the end of the Late Bronze Age, around 1200 b.c., the Hittite Empire of Anatolia collapsed. While that collapse has been well studied, the effects on Hittite-held lands are less so, with many archaeologists positing an abandonment in Hittite territories for a period of time early in the Iron Age. Recent excavations at Çad?r Höyük, 70 kilometers from the Hittite capital, have revealed both typical Hittite material culture belonging to the Late Bronze Age, including mass-produced ceramics and massive fortifications, as well as evidence suggesting that the site’s residents faced challenges, and adapted accordingly, in the wake of Hittite withdrawal and collapse, during the Early Iron Age. The architecture, ceramics, and zooarchaeological evidence from this rural settlement suggest ways in which residential continuity, cultural resilience, and technological and economic adjustments allowed inhabitants to survive and rebound in the face of political instability.     

The Iron Age lower settlement at Kabri revisited

ABSTRACT

During the 2017 excavation season at Tel Kabri, Iron Age remains were found cutting into the western part of the Middle Bronze Age palace. These remains consisted of a segment of a large structure and a series of sizable pits. Similar Iron Age remains were unearthed during previous soundings in Areas D and F of the excavation and were loosely dated to the Iron Age II. The ceramic assemblage from these soundings demonstrated a disproportionate number of imports and cooking pots, which prompted the excavators to suggest that the lower settlement was engaged in the processing of agricultural products connected to the nearby forts located elsewhere on the tell. A recent re-examination of the pottery from the previous excavations suggest that the forts could have only existed during the Iron Age IIA and IIC. Our examination of the pottery indicates that the imports can be dated to the Iron Age IIA, while the large number of cooking pots should mostly be dated to the Iron Age IIC. We would therefore like to suggest a new interpretation for the function of the lower settlement at Kabri during the Iron Age II in relation to the forts and the political reality in the Galilee at that time.     

The Bronze Age landscape of the Bjäre peninsula,southern Sweden,and its relationship to burial mounds

Palaeoecological analyses from a small fen deposit, combined with pollen analysis from buried soil profiles under prehistoric burial mounds, have been used to investigate the timing and vegetation change associated with the Holocene development of a cultural landscape in southern Sweden. Traditional pollen analysis is complemented with plant macrofossil analysis and soil pollen analysis from within and in close proximity to the burial mounds in the coastal Bjäre peninsula, well known for its high density of well-preserved Bronze Age monuments. The vegetation development is linked to the construction of the burial mounds. A marked increase of cultural impact on the landscape is recorded during the Neolithic–Bronze Age transition and estimates of landscape openness suggest that by the onset of the Bronze Age, forest cover was only 20–40%, falling to 10% in the immediate vicinity of the burial mounds themselves. The coastal strip appears to have been affected by human activity to a greater extent and at an earlier date than sites from further inland in southern Sweden and the Bronze Age burial mounds were most likely designed to be visible in a largely deforested landscape.     

Bronze Age Field Systems in the Thames Valley

In the last two decades excavation along the River Thames has shown the remarkable survival of Bronze Age field systems. A managed farming landscape emerged in this lowland area during the Middle Bronze Age and continued to develop until the end of the Late Bronze Age. In the latter period the field systems were divided into several regional groups in each of which there was a high status settlement and a concentration of river metalwork. They provide evidence for a predominantly pastoral economy in the Thames Valley on a scale which may have supported an increasingly hierarchical society. Settlements and field systems were abandoned during the Late Bronze Age, and by the Bronze Age–Iron Age transition new sites were largely confined to the extreme upper reaches of the Thames, an area which had been peripheral to the alliance and exchange system that had operated downstream.     

Cultivation History Beyond the Periphery: Early Agriculture in the North European Boreal Forest

We have investigated the environmental history of human occupation and the development of agriculture in the eastern interior Lake District of Finland. The material consists of archaeological data, which is reviewed in topographical and agrogeological context, and pollen analytical evidence of agricultural indices from eight precisely dated (varved) lake sediment sequences. Before the Viking Age, archaeological evidence, consisting of stray finds, dwelling sites, and graves, is very scarce. Iron Age finds are clearly confined to the lowland environs with silty and clayey soils. During the Viking Age, the number of stray finds multiplies and the first cemeteries are established. Comparison between Viking and Crusade Period finds reveals a topographic shift toward higher locations and morainic soils. Most of the cup-stones are located on upland sites—that is, not in connection with known Iron Age sites. These are interpreted as medieval indicators of slash-and-burn farming of the fertile but stony supraaquatic morainic soils. There is pollen analytical evidence of sporadic cultivation in the area from the Bronze Age onward. Afterca. AD 700, the occurrence of cereal pollen grains becomes regular but remains discontinuous at each site until after the turn of the millennium. There is then an exponential rise in the cereal pollen rain, indicating a fully agricultural population.     

The Potential for Dating the Old Scatness Site,Shetland, By Optically Stimulated Luminescence

A series of deposits from the agricultural infield of the multiperiod settlement mound, Old Scatness, were investigated for their potential to yield optically stimulated luminescence dates. Luminescence properties of quartz grains were found to vary through the sequence, but dates were successfully obtained from five deposits, including anthropogenic soils, windblown sands and sands within midden deposits. Single‐aliquot equivalent dose measurement was found to be the most appropriate method for dating the deposits. The OSL dates obtained accorded well with the dates provided by archaeological evidence and included the post‐medieval, Iron Age, Bronze Age and Neolithic periods of Shetland, while a substantial midden was dated to the Bronze/Iron Age transition.     

SHIFTING SETTLEMENT PATTERNS IN THE SOUTHERN JORDAN VALLEY AND DESERT FRINGES OF SAMARIA DURING THE EARLY BRONZE AGE I PERIOD

Abstract

This study deals with the unprecedented settlement activity during the Early Bronze Age I that has been recently recorded in the Jordan Valley and the desert fringes of Samaria. The increase in the number of sites primarily characterises the latter part of the period (Early Bronze Age IB), and is accompanied by two other important phenomena: population inroads into new regions, and the first appearance of fortified sites. A profound crisis at the end of the period resulted in the almost complete abandonment of the valley sites and the concentration of settlement along the eastern foothills of Samaria.     

The little ice age in the Scottish Highlands and Islands: Documenting its human impact

This paper examines the Little Ice Age in the Scottish Highlands and Islands and uses documentary evidence to show its impact on the farm economy. It has three sections. The first examines how Highland climate may have changed during the Little Ice Age, and notes that increased storminess was probably as much a factor as lower annual mean temperatures. The second takes the most severe phase of the Little Ice Age, the Maunder Minimum, 1645–1715, and uses rests or eases of rent to show how it stressed the farm economy. The third examines evidence for the abandonment of land during the Maunder Minimum. As well as arguing that we need to see abandonment in its social as well as physical setting, it highlights the role played by the temporary abandonment of land and suggests that such abandonment along the western seaboard probably indicates the impact of increased storminess.     

A late Holocene pollen record from Lake Almalou in NW Iran: evidence for changing land-use in relation to some historical events during the last 3700 years

A pollen diagram was prepared from Lake Almalou, a volcanic crater wetland located on the eastern flanks of the Sahand Volcanic Complex in NW Iran. The core provides a 3700-year record of human activity and environmental change in an upland region. We attempt to relate vegetation changes to both climatic change and historical events. Variations of anthropogenic pollen indicators suggest several phases of intensified human activities. Two strongly expressed agricultural phases are dated at about 2450–2220 cal BP (Achaemenid Empire) and 230–30 cal BP (collapse of Safavid Dynasty to the modern period). Historical rather than climatic events appear to be the main controlling factors for upland land-use dynamics. Fruticulture has been practiced in the region at least since the Iron Age, reaching its maximum importance 1500–1250 cal BP during the reign of Sassanid Empire; it declined by the time of Islamic conquest of Iran (651 AD). The Little Ice Age is tangibly recorded by higher lake water levels most probably due to both lower summer temperatures and higher annual precipitations. Low values of cereal-type and cultivated tree pollen during this period may indicate a change in the lifestyle from the cultivation of fields and orchards to a more nomadic life dominated by summer pasture. The modern period (1850 AD onwards) is characterized by expansion of agricultural activities to upland areas and intensified pastoralism.     

Use of ulan-khada bay at lake baikal in the holocene (based on fauna remains)

The article presents the results of studies of faunal remains from the Ulan-Khada multilayered settlement – one of key habitation sites in the Cis-Baikal region providing information for reconstructing environmental and cultural changes during the Holocene. A complete analysis of the fauna assemblage obtained over the course of long-term excavations is given. For the fi rst time, the site's ichthyofauna is described. The mammalian species composition is revised. Species diversity is evaluated across the time span from the Final Mesolithic to the Late Iron Age. These studies have demonstrated that the main activities at the site during the Neolithic and Bronze Age included seal and ungulate (roe and red deer) hunting. Fishing was also important, especially 4.2–3.8 thousand years ago (Bronze Age).
