Understanding Abandonments in the North American Southwest

The North American Southwest is renowned for its rich archaeological record. Thousands of prehistoric houses and ceremonial centers remain partially standing or form mounds that mark prehistoric villages that were once actively occupied and remain important to the descendants. The visibility of archaeological remains has sparked interest in questions of abandonment among archaeologists and the lay public. We explore reasons for this interest, how it is manifest in archaeological research, and how perception of that research influences popular views of the past and of native people. Our focus is on explanations for the causes of site and regional abandonment as well as on explications of the processes by which abandonments occur. Essential to our perspective is the view that abandonment is a process that involves decisions to move, which may be promoted by dire circumstances, but which are most often settlement strategies. The process of moving requires economic, social, and political decisions about the places from which people move and to which they move.     

The Difficult Place of Deserted Coasts in Archaeology: New Archaeological Research on Cooks Beach (Pukaki), Coromandel Peninsula,New Zealand

Sites which have been occupied semi-continuously in the past present some inherent difficulties for archaeology. Here we present new research from a coastal site on the North Island of New Zealand at Cooks Beach where anthropogenic vegetation changes are seen using microfossil analysis of obsidian tools, sediments and pit fill. The results indicate the initial presence of people in AD 1300–1400 followed by subsequent periods of disuse or abandonment and sweet potato (Ipomoea batatas) cultivation. Around the time of initial settlement, obsidian from this location is found at sites across the country. After AD 1400 the area appears to be deserted for a century or more, after which we see evidence for the cultivation of sweet potato in AD 1500 as evidenced by extensive soil modification and numerous storage pits. There is no evidence of a permanent settlement at the site. The geographic distribution of Cooks Beach obsidian was constricted while the site was used for sweet potato cultivation, a pattern often attributed to increased warfare. It appears cultivation was abandoned after AD 1650 marking a second secession of use, a fact confirmed in AD 1769 when Captain Cook visited the area. We consider the possible drivers for the late abandonment of cultivation at Cooks Beach.     

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.     

Roman Rhine settlement dynamics evidenced by coin distribution in a fluvial environment (Oedenburg,Upper Rhine,France)

On the basis of archaeological and alluvial records, this paper presents the first spatial analysis of artefacts in relation to the evolution of the Rhine River, at the Gallo-Roman site of Oedenburg, during the first four centuries AD. The dataset consisted of several thousand Roman artefacts found by pedestrian prospecting over the last twenty years, over half of which were coins. This dataset was used together with high-resolution topography and geomagnetic mapping, to reconstruct settlement evolution, both on the terrace and in the floodplain. A comprehensive monetary chart has been compiled for the Oedenburg site, which highlights four major phases of settlement. These results provide a possible causal link connecting historical factors and alluvial events with intra-site evolution. Therefore, while changes observed during Phases I (until AD 68), II (AD 69 to AD 180) and III (AD 180 to AD 295) seem largely related to historical and societal events, Phase IV (AD 295 to AD 402) shows patterns of abandonment of the lower part of the floodplain that may well be related to an unusually humid period in the fourth century. These results are set in a broader context, from the Rhine catchment area to the Alps, and are in agreement with the wet conditions also documented in alluvial, lacustrine, geomorphological and palynological records in Germany (Lahn River, Lake Constance, Lake Nussbaumen, Kaisersthul area and the Black Forest). Studying the intra-site spatial distribution of artefacts with high temporal constraints, at a long-lived site with contrasted topography, opens new avenues for the detection of discreet events such as a higher water table, affecting only the lower zone.     

The changing World : A review

Abandoned farmsteads are a characteristic feature of Scotland's marginal uplands. Yet little is known of the quantity or location of these early settlements or indeed, of the date of their abandonment. This paper outlines a method of mapping and dating deserted settlement sites and exemplifies the method by reference to abandonment in the Lammermuir Hills in South East Scotland. In this area alone it appears that more than 230 settlements were abandoned before 1860, and a further 104 over 1860‐1970. The scale of this abandonment is greater than has been generally supposed and must lead to speculation about the extent of former settlement elsewhere in upland Scotland.     

The Late Roman Landscape of the Northern Levant: A view from Tell Qarqur and the lower Orontes River Valley

This paper presents a review and synthesis of archaeological surveys in western Syria and southern Turkey, alongside finds from recent excavations at Tell Qarqur, Syria, revealing regional patterns of late Roman settlement and land use in the lower Orontes River Valley. Survey data show that the late Roman period witnessed a peak in settlement density, with the extension of occupation into previously unoccupied areas and widespread agricultural intensification. Excavations of a typical lowland site at Tell Qarqur reveal an opulent building complex, possibly a church, with a columned hall, elaborate mosaic floor and frescoed interior. Analysis explores the process of agricultural intensification during the late Roman period, the relationship between lowland settlements and the better‐known Dead Cities of the limestone massif to the east, and the ultimate abandonment of the settlement system following the seventh century AD.     

Climate deterioration and land-use change in the first millennium BC: perspectives from the British palynological record

Climate deterioration at around the time of the Bronze Age/Iron Age transition has for long been argued to have resulted in upland abandonment in northern and western Britain, and recent research has provided evidence that a major climate downturn from 850 cal BC caused settlement abandonment in western Europe and potentially worldwide. It is, however, unclear to what extent only ‘marginal’ sites were affected, due to the lack of any systematic attempt to view the evidence for settlement and land-use change across a range of landscape types with differing sensitivities to environmental change. This paper addresses this issue by an evaluation of 75 pollen sequences spanning the late Bronze Age and early Iron Age in Britain to assess whether climatic deterioration was sufficient to cause widespread land abandonment. The results provide no evidence for wholesale land-use change at this time; the overall picture is one of continuity of land use or even increased agricultural activity. There are, however, hints of regional variability, with a greater tendency to abandonment of upland areas in Wales, and signs of woodland regeneration in agriculturally productive areas of lowland central southern England. The latter pattern may reflect a combination of rising ground-water levels affecting local land-use in the immediate vicinity of the mires which provide the source of the pollen data, against a backdrop of regional-scale social and economic changes at the Bronze Age-Iron Age transition.     

Local diversity in settlement,demography and subsistence across the southern Indian Neolithic-Iron Age transition: site growth and abandonment at Sanganakallu-Kupgal

The Southern Indian Neolithic-Iron Age transition demonstrates considerable regional variability in settlement location, density, and size. While researchers have shown that the region around the Tungabhadra and Krishna River basins displays significant subsistence and demographic continuity, and intensification, from the Neolithic into the Iron Age ca. 1200 cal. BC, archaeological and chronometric records in the Sanganakallu region point to hilltop village expansion during the Late Neolithic and ‘Megalithic’ transition period (ca. 1400–1200 cal. BC) prior to apparent abandonment ca. 1200 cal. BC, with little evidence for the introduction of iron technology into the region. We suggest that the difference in these settlement histories is a result of differential access to stable water resources during a period of weakening and fluctuating monsoon across a generally arid landscape. Here, we describe well-dated, integrated chronological, archaeobotanical, archaeozoological and archaeological survey datasets from the Sanganakallu-Kupgal site complex that together demonstrate an intensification of settlement, subsistence and craft production on local hilltops prior to almost complete abandonment ca. 1200 cal. BC. Although the southern Deccan region as a whole may have witnessed demographic increase, as well as subsistence and cultural continuity, at this time, this broader pattern of continuity and resilience is punctuated by local examples of abandonment and mobility driven by an increasing practical and political concern with water.     

First contribution of the excavation and chronostratigraphic study of the Ruways 1 Neolithic shell midden (Oman) in terms of Neolithisation,palaeoeconomy, social-environmental interactions and site formation processes

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.     

Long-Term Occupation and Seasonal Settlement of Eastern Eurasian Pastoralists at Begash,Kazakhstan

Abstract

Recent excavations of the prehistoric pastoralist settlement of Begash, located in the Semirech'ye region of eastern Kazakhstan, provide evidence of one of the earliest pastoralist settlements in the eastern Eurasian steppe region. The archaeological complex at Begash includes a multi-period cemetery and rock art in addition to the settlement—a site complex that is well distributed throughout the koksu River Valley. Excavations at Begash have revealed three major phases of architectural development and six phases of material transition and site use, dated by a series of 34 calibrated radiocarbon AMS dates. These data demonstrate that mobile pastoral populations were active in the Dzhungar Mountains and koksu River Valley (Semirech'ye) as early as 2460 CAL B.C., more than 800 years earlier than previous theories suggested. Pastoralist activity at this domestic locale spans nearly 4000 years, with no archaeological evidence for long-term abandonment of the site in prehistory. Rather the occupational phases of the site are only interrupted by short-lived periods of disuse followed by centuries of re-engagement by local pastoralist communities. Thus, the broadly continuous record of material culture, domesticated faunal remains, and settlement at Begash index a local evolution of herding economies in Semirech'ye throughout the Bronze Age, beginning in the middle part of the 3rd millennium B.C. Ultimately, the data from Begash contribute a new perspective on the dynamic nature of Eurasian mobile pastoralists while also illustrating broad continuity in the settlement ecology of local populations that had a key role in the regional transmission of numerous innovations throughout the Bronze Age and later.     

Using event-history analysis to examine the causes of semi-sedentism among shifting cultivators: a case study of the Haudenosaunee,AD 1500–1700

Event-history analysis is often used in the social sciences to study the occurrence of particular events over the lifespan of individuals and the impact of various factors on the rate at which those events occur. Like individuals, settlements can be analyzed and important events, such as founding or abandonment, can be studied using this method. Thus, as Richard Paine (1992) has noted, the technique can be useful in archaeological investigations of settlement processes. In this research we use it to explore the causes of settlement abandonment among a temperate shifting cultivators in an attempt to better understand the ecology of this adaptation and in order to evaluate the merits of the method. The sixteenth- and seventeenth-century Haudenosaunee (Iroquois) of northeastern North America present an interesting case study for applying event-history analysis to archaeological settlement dynamics because of the wealth of archaeological settlement data and detailed historic record that allows us to parse out historical factors and analyze the remaining ecological factors. We use event-history analysis as an alternative means for evaluating the relative and absolute effects of several variables that may have been predictive of the lifespan of settlements and the timing of their removal. The results suggest that the decision to move from a village was a complex process in which the population size of a village may have been the single most important, but not the only, determinant of settlement duration.     

The potential of chironomid (Insecta: Diptera) larvae in archaeological investigations of floodplain and lake settlements

The head capsules of chironomids (Insecta: Diptera) are well preserved in sediments and can be recognised to a high taxonomic level, usually genus and sometimes species. Work on lake sediments has shown that they can be accurate indicators of water temperature, oxygen regimes, and nutrient status (particularly total phosphorus and chlorophyll-a), as well as heavy metal pollution. No systematic chironomid analyses, however, have previously been undertaken on archaeological deposits. In order to address this we assessed the use of chironomids in three types of archaeological deposit; firstly, a lake core at the edge of a lake settlement (crannog), secondly, a palaeochannel infill adjacent to a multi-period settlement site and lastly, a Roman well deposit from a floodplain environment. The chironomid assemblages are shown to vary significantly both between and within the sites and reflect the immediate environment and the adjacent area. The lake sediment assemblage reflects the construction of the crannog through elevated levels of organic detritus, wood and woody debris. The palaeochannel assemblage reveals changing natural conditions and nutrient enrichment probably associated with settlement during the Saxon period. The well assemblage is taxonomically restricted and indicative of organic debris, dead plant material, animal dung and possibly human effluent deposited after abandonment of the well. Dry storage of the palaeochannel and well sediments for several years did not appear to affect the concentration or state of preservation of the head capsules. The chironomid reconstructions are shown to provide an additional indicator of human activity which has the potential to provide quantitative data on the character of aquatic environments associated with archaeological sites.     

A Test of Ideal Free Distribution Predictions Using Targeted Survey and Excavation on California’s Northern Channel Islands

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.     

Urbanization in Iron Age Europe: Trajectories,Patterns, and Social Dynamics

The development of the first urban centers is one of the most fundamental phenomena in the history of temperate Europe. New research demonstrates that the earliest cities developed north of the Alps between the sixth and fifth centuries BC as a consequence of processes of demographic growth, hierarchization, and centralization that have their roots in the immediately preceding period. However, this was an ephemeral urban phenomenon, which was followed by a period of crisis characterized by the abandonment of major centers and the return to more decentralized settlement patterns. A new trend toward urbanization occurred in the third and second centuries BC with the appearance of supra-local sanctuaries, open agglomerations, and finally the fortified oppida. Late Iron Age settlement patterns and urban trajectories were much more complex than traditionally thought and included manifold interrelations between open and fortified sites. Political and religious aspects played a key role in the development of central places, and in many cases the oppida were established on locations that already had a sacred character as places for rituals and assemblies. The Roman conquest largely brought to an end Iron Age urbanization processes, but with heterogeneous results of both abandonment and disruption and also continuity and integration.     

Regional Survey and the Boom-and-bust Countryside: Re-reading the Archaeological Evidence for Episodic Abandonment in the Late Roman Corinthia

This paper reexamines the archaeological evidence for three episodes of rural abandonment and resettlement in the countrysides of Late Roman Greece (200–700 CE): an abandoned Late Hellenistic-Early Roman countryside (second century BCE to third century CE), a decline in the third to early fourth centuries CE, and the Dark Age beginning in the seventh century CE. The first and third episodes of abandonment, especially, have sharply defined Late Antiquity (250–700 CE) as a healthy period of new rural settlement and economic resurgence, and the entire pattern has been described in the terms of “boom-and-bust” demographic and economic cycles. Closer readings of the archaeological data can contribute to more sensitive pictures of continuity and change in settlement and connectivity in the late antique Corinthian countryside and other regions in Greece.     

Medieval Coastal Sand Inundation in Britain and Ireland

HISTORICAL, ARCHAEOLOGICAL AND GEOMORPHOLOGICAL data indicate that many of the coastal dune formations of Britain and Ireland underwent significant accretion in the medieval and post-medieval periods. The changes wrought by sand-blows to settlement and agriculture were far-reaching, and in some cases devastating. Contemporary attempts to stave off their effects were in many cases the prelude to settlement shift and abandonment. The desertion of sand-inundated settlements has left a rich but fragile archaeological resource concealed under coastal sand-dunes. Exposure, deflation and erosion remain serious challenges to the management and conservation of these landscapes. Archaeological methods applied in sand-dune landscapes are reviewed, with the aim of outlining the range of techniques and approaches available for research and management.     

Pit Structure Abandonment in the Four Corners Region of the American Southwest: Late Basketmaker III and Pueblo I Periods

Abstract

Anasazi pit structures dating to the Basketmaker III and Pueblo I periods (ca. A.C. 500 to 900) in the Four Corners region of the American Southwest experienced a variety of different processes at abandonment, ranging from dismantling the superstructure to intentional burning. Data from 88 pit structures are used to examine the relationship between these processes and the causes of pit structure abandonment. Results suggest that burning was not usually the result of catastrophic events, such as accident or warfare, but may be part of ritual activities or even a response to insect infestation. The incidence of burning does not seem to increase over time as a result of the postulated transition of pit structures from domestic to ceremonial uses. Dismantled and trash-filled pit structures suggest that new dwellings were often constructed near abandoned ones, perhaps because the old structure was deteriorating. A few pit structures with human bodies on the floor at the time of abandonment may signal the desertion of the entire settlement.     

Anglo-Saxon Economy and Ecology by a Downland Stream: A Waterlogged Sequence from the Anglo-Saxon Royal Settlement at Lyminge,Kent

Palaeoecological and geoarchaeological investigations which cover the Anglo-Saxon period are rare, particularly in chalk downland landscapes which are considered to have limited palaeoenvironmental potential. The present study explores a sequence which can be directly related to the occupation history of the major Anglo-Saxon settlement at Lyminge, Kent. This work demonstrated a sequence of palaeochannels and organic deposits associated with the latter part of an archaeological sequence which spans the 5th to the 11th centuries AD. A range of evidence for the environment and economic activity is presented which suggests landscape continuity, possibly stretching back as far as the Romano-British period. The sequence revealed worked wood and evidence for livestock management and cereal cultivation, some of which is contemporary with the final phases of occupation of a 7th century ‘great hall complex’ and its subsequent transformation into a royal monastery. Agricultural activity following the abandonment of the pre-monastic settlement area caused this stream margin to become gradually buried by ploughwash which displaced the channel over time and sealed the organic deposits. It is incredibly rare to find such organic preservation in direct association with an Anglo-Saxon downland rural settlement and this is the first time that such a sequence has been analysed in association with the latter phases of a known Anglo-Saxon royal and monastic centre.     

Julfar and the urbanisation of Southeast Arabia

The fourteenth-sixteenth-century town of Julfar (al-Mataf) in Ras al-Khaimah (UAE) is one of the most fully investigated archaeological sites in the Gulf, having been the subject of seven different excavation projects. Evidence from the published reports, when brought together, provides a detailed and coherent picture of the development of the site from a small fishing community in the mid-fourteenth century to a fully urbanised settlement by the mid-fifteenth century, and then attests to its eventual decline and abandonment by the late sixteenth century.
Julfar was the first example of true urbanism in this part of Arabia, and therefore marks a significant historical turning point. Its development is believed to have been linked to the expanding mercantile economy of Hormuz, but it occurred at the same time as a period of spectacular rural growth in its own immediate hinterland, evidence for which has been produced by archaeological field survey. Together these phenomena suggest the development of a local market economy, perhaps for the first time, which would have had significant implications for the social and economic structure of the area.     

The Peak Dwellers

LONGBURY BANK, Dyfed is a native British early medieval settlement occupied in the 6th and 7th centuries A. D. The excavations in 1988–89 produced a series of artefacts which provide evidence of high status: imported Mediterranean pottery; continental pottery and glass; fine metalworking debris; and an unusual Type G penannular brooch. The site is unusual in being undefended and it is suggested that it belongs to a newly recognized class of undefended high status secular sites, other possible examples of which are discussed. The site is placed in its historical and landscape context through the use of pre-Norman and later documentation which appears to show a major shift in settlement in the 8th or 9th centuries.
