Contributions to the agrarian history of Eastern Arabia II. The cultivars

Following on from an earlier study of agricultural implements and cultivation techniques in eastern Arabia, this paper presents the palaeobotanical and ethnohistoric evidence available on early cultivars in the region from the late 4th millennium B.C. through the pre-modern era. The introduction of new crops is discussed and, where possible, the evidence is marshalled which pertains to the origins of those new introductions and the dates of their arrival in the Gulf region.     

Clearances and Clearings: Deforestation in Mesolithic/Neolithic Britain

Clearances, interpreted from pollen records during the Mesolithic and Neolithic of Europe, are generally ascribed to purposive deforestation which is compatible with the transition model, whereby early Neolithic economic strategies are a development of late Mesolithic intensification of wild plant food husbandry. This paper considers the role of natural processes in creating clearings and the role of inadvertent impact of human activity on forest processes, including woodland regeneration. The role of climate, wind-throw and lightning strikes in creating clearings and forest instability is emphasised and the evidence discussed from sites which may be interpreted as resulting from opportunistic human use of natural clearings. Unfortunately, regional pollen diagrams lack sufficient spatial resolution to detect the size of isolated clearings or establish the spatial variation in forest composition that was intimately related both to forest ecology and the effects of subtle human impacts. This may be the major reason for an apparent contradiction between pollen evidence of Neolithic impact and the archaeological record. Moreover, early Neolithic agricultural activity may have been concentrated in valley bottoms, which is undetectable in regional pollen diagrams. Alternative models need to be considered, which include culturally specific exploitation of the local environment, along with the inadvertent ecological repercussions of pre-agricultural and early-agricultural human activities in naturally dynamic woodlands.     

Natron as a flux in the early vitreous materials industry: sources,beginnings and reasons for decline

Natron deposits, the best known of which being those at Wadi Natrun in Egypt, have been used as the flux in the production of vitreous materials from the early 4th millennium BC onwards. In the present paper, the history of the use of natron as a flux is traced from its beginnings in the glaze of Badarian steatite beads, through its use in glass production starting in the 1st millennium BC, until its apparent shortage during the 7th to 9th centuries AD, and its subsequent replacement by plant ash during the 9th century AD. Documentary evidence for possible natron sources in Egypt, including the Wadi Natrun, and around the eastern Mediterranean is summarised, and the results of recent fieldwork at the Wadi Natrun and at al-Barnuj in the Western Nile Delta are presented. The possible reasons for the apparent shortage of natron from 7th to 9th centuries AD and its subsequent replacement by plant ash as the flux used in glass production during the 9th century AD are then considered. These include the possibility that, because of the massive scale of glass production, the demand for natron exceeded its supply; the possible effect of climatic changes; and the potentially disruptive role of political events in the Wadi Natrun–Delta region.     

Galilee Blooming: First palynological and archaeological data from an Early Byzantine Cistern at Horvat Kur

Abstract

Preliminary archaeological and palynological results are presented from an early Byzantine cistern of the village Horvat Kur in eastern Lower Galilee/Israel. The rural site was settled from the Hellenistic until the Early Arab period, its synagogue was constructed shortly after 425 AD and renovated sometimes during the 2nd half of the 6th century AD. It was abandoned probably as a consequence of the earthquake of 749 AD. The intact and properly sealed cistern contained complete or fully restorable pottery. Two cooking pots from the early 5th century AD comprised sediments which was sampled for palynological purposes. Both samples, as well as a sample from the soil beneath one of the pots and a modern surface sample from the site, revealed well preserved palynomorphs in comparably high concentration showing a great potential of the cistern as a pollen archive. The pollen content points to an open, grassy semiarid landscape with an apparent scarcity of cultivars and trees in the vicinity of the site and an abundance of herbs, especially Asteraceae, which are still commonly found in modern regional vegetation.     

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.     

Detecting the environmental impact of the Baltic Crusades on a late-medieval (13th–15th century) frontier landscape: palynological analysis from Malbork Castle and hinterland,Northern Poland

Palaeoecological analysis of peat deposits from a small bog, combined with pollen analysis of sediments infilling the moat of the nearby Teutonic Order castle at Malbork, have been used to examine the ecological impact of the Crusades on the late-medieval landscape of Northern Poland. Studies of the environmental impact of the Crusades have been almost exclusively informed by written sources; this study is the first of its type to directly investigate the environmental context of Crusading as a force of ecological transformation on the late-medieval Baltic landscape. The pollen evidence from Malbork Castle and its hinterland demonstrate that the 12th/13th–15th centuries coincide with a marked transformation in vegetation and land-use, characterized by clearance of broadleaved woodland and subsequent agricultural intensification, particularly during the 14th/15th centuries. These changes are ascribed to landscape transformations associated with the Teutonic Order’s control of the landscape from the mid-13th century. Human activity identified in the pollen record prior to this is argued to reflect the activities of Pomeranian settlers in the area. This paper also discusses the broader palaeoecological evidence for medieval landscape change across Northern Poland.     

Marine resource intensification in Viking Age Europe: the molluscan evidence from Quoygrew,Orkney

This paper addresses whether molluscan evidence from Orkney can shed light on the hypothesis that there was a trend towards the intensification of marine resource use at the end of the first millennium AD. The stratified middens of Quoygrew, which date from approximately the 10th to the 13th centuries, are shown to contain predominantly limpets, which may have been used for baiting fish. From metrical data it is shown that these limpets reduce in size through time. In order to test whether this observation is related to intensification in exploitation, analysis of limpet shoreline location was carried out. In addition, age data were used to demonstrate a lowering of average age which suggests intensification in gathering rather than environmental influences, particularly during the 11th–12th centuries at this site.     

Soils and vegetation history of abandoned enclosures in the New Forest,Hampshire, England

Soil profiles buried beneath earth banks of five abandoned enclosures, ranging in age from late Bronze Age to early 19th century AD, were compared with unburied profiles inside and outside the enclosures. Soil particle size analyses and micromorphological studies show that the banks were constructed of mixed topsoil and subsoil from adjacent ditches; on some banks the soil has begun to podzolize. At the two oldest sites (Dark Hat and Long Slade Bottom, which are late Bronze or Iron Age) the soils within the enclosures were homogenized, probably by occasional cultivation for cereal growing. At Dark Hat an ironpan has developed on the upper surface of a layer compacted by smearing during cultivation. The later enclosures, at Burley Moor (Anglo-Saxon), East Boldre (mediaeval) and Hatchet Gate (early 19th century AD), were probably used entirely for pasture. Pollen assemblages from the buried soils and overlying banks, and chemical comparisons of the buried soils with profiles inside and outside the enclosures together provide new evidence for a history of soil and vegetation changes over the past 2500–3500 years. Heathland vegetation associated with podzolic soils existed on plateau gravels before the late Bronze Age, but on other parent materials heath vegetation and acidic soils with incipient podzolization appeared only in later periods. The present patchy vegetation pattern of mainly deciduous woodland with open areas of ferny grassland and heath seems to have persisted since before the late Bronze Age. The most obvious human influences on the vegetation during the last 2000 years have been periodic temporary use of open areas and woodland clearings for protected grazing.     

Testing the sustainability and sensitivity to climatic change of terrace agricultural systems in the Peruvian Andes: a pilot study

The results of an integrated geoarchaeological and palaeoecological pilot study of a prehistoric agricultural terrace and nearby mire basin are presented. They reveal two stages of terrace construction for the cultivation of Zea mays during the Middle Horizon (615–695 AD) and late, Late Intermediate Period (1200–1400 AD). These stages were strongly associated with evidence for vegetation succession, destabilisation and erosion of the surrounding landscape, and changes in mire surface wetness. The reasons for agricultural terrace abandonment and/or reconstruction are uncertain, with only circumstantial evidence for climatically induced agricultural change.     

Agricultural potential and actualized development in Hawai’i: an airborne LiDAR survey of the leeward Kohala field system (Hawai’i Island)

Archaeological investigations of Hawaiian agriculture have relied on relatively coarse-grained data to investigate archipelago-wide processes, or on fine-grained data to examine patterning within localized zones of agricultural production. These trade-offs between spatial coverage and data resolution have inhibited understanding of both spatial patterns and temporal trends. Our analysis of 173 km² of high-resolution airborne Light Detection and Ranging (LiDAR) data for leeward Kohala, Hawai’i Island identifies spatial and temporal patterning in regional agricultural development. Differential densities of alignments suggest variable levels of agricultural intensity. Agricultural processes of expansion, segmentation, and intensification can also be discriminated, with distinct zones of the field system having undergone different mixes of development. Areas within the field system with moderate to high levels of both average production and variability in production (determined using a climate-driven productivity model) were utilized relatively early in a highly intensified manner; these areas often underwent processes of segmentation and intensification. Less productive areas were developed later and exhibit evidence of expansion with lower amounts of segmentation and intensification, at set levels of intensity. The spatial and temporal variability in agricultural activities was influenced by the diverse environmental conditions across the landscape as well as variation in cultivars and cultivation techniques. Combining the high-resolution LiDAR data from a large area with potential productivity modeling allows for a more fine-grained understanding of agricultural development in this region of the Hawaiian archipelago.     

Hunting intensification and the Hohokam “collapse”

The role of long-term demographic stress in the “collapse” of the Hohokam culture of southern Arizona is an open question. If chronic imbalances between population levels and food production, as opposed to catastrophic events, were key factors in the population decline of the 15th century, then the archaeological record should produce evidence for resource stress prior to the near-abandonment of the region. It is difficult to document resource depression in archaeofaunas from southern Arizona, however, because they are dominated by small game throughout the agricultural sequence. Furthermore, in an ecologically and economically diverse region, it is difficult to apply data from an individual site to a region-wide phenomenon like the Hohokam demographic decline. This study uses data from 85 faunal assemblages to explore hunting strategies from the earliest agricultural villages to the cessation of archaeologically visible occupation of the region. One means of hunting intensification employed by the Hohokam was to diversify beyond a focus on staple rabbit species, through the use of fish, birds, artiodactyls, and smaller terrestrial game. Diversification is measured in this study through evenness indices. These indices suggest that demographic stress was increasing in the dense population centers of the Salt and Gila River basins prior to the “collapse.”     

The Geography of the Anthropocene in New Zealand: Differential River Catchment Response to Human Impact

New Zealand provides a useful environment to test the notion that the Anthropocene is a new geological epoch. There are two well‐dated anthropogenic impact ‘events’: Polynesian settlement c. AD 1280, and European colonisation c. AD 1800. Little attention, however, has been given to regional catchment response to these, although it has been assumed that both Polynesian and European farming and land use management practices significantly increased erosion rates across most of New Zealand. This paper addresses the nature and timing of human impacts on river systems using meta‐analysis of a recently compiled nationwide database of radiocarbon‐dated fluvial deposits. This shows highly variable human impacts on erosion and sedimentation in river systems, which are often difficult to separate from naturally driven river activity. Catchment‐scale data with high resolution dating control record clearer evidence of human disturbance. In Northland, anthropogenic alluviation is recorded from c. AD 1300 linked to early Polynesian settlement, enhanced further in the late 19th and 20th centuries by European land clearance, when sedimentation rates exceeded 25 mm year^?1. This study demonstrates significant geographical variability in the timing of human impact on river dynamics in New Zealand, despite two synchronous phases of human settlement, and highlights the difficulty of formally designating a simple and single ‘Anthropocene Epoch/Age’.     

The Prehistoric Local Environment of Grasshopper Pueblo,Arizona

Abstract

The prehistoric local environment near Grasshopper Pueblo, east-central Arizona, is reconstructed by analysis of mammalian microfauna recovered at the site. Changes in the vegetation surrounding the pueblo during the span of occupation (ca. 1300–1400 A.C.) are described and the present and past environments at the site are contrasted. Paleoenvironmental analyses to date have failed to produce evidence for a rapid prehistoric climatic shift with negative consequences for agricultural productivity.     

Contributions to the agrarian history of Eastern Arabia I. Implements and cultivation techniques

This paper focuses on early agricultural implements in eastern Arabia, examining four hoe blades and an ard share ranging in date from mid-2nd millennium B.C. through the Seleucid or Parthian period. These objects are considered in light of more recent ethnohistoric evidence pertaining to garden cultivation by hand and the plough in the region.     

THE 'ROMANISATION'of TURDETANIA

Summary: Turdetania was one of the Iron Age cultural blocks which emerged after the disintegration of Tartessos in the later 6th century BC. It corresponded largely to the lower Guadalquívir valley of southern Spain. From the early 2nd century BC it formed the heart of the Roman province of Hispania Ulterior and, from the later 1st century BC, Hispania Baetica. This paper sets out to examine the Romanisation of the region from an indigenous perspective rather than a Romano-centric viewpoint. Until the mid-first century BC Roman impact was negligble and merely served to reinforce the Turdetanian prestige goods economy. Subsequently, however, the foundation of coloniae and a consequent increase in commercial activity were catalysts for rapid change. A new hierarchy of dominant and dependent centres arise and, by the early 1st century AD, the agricultural wealth of the region was being more directly exploited for Rome's benefit. This relatively 'delayed'Romanisation is interpreted as native resistance to cultural change.     

The impact of human activities on the natural environment of the Canary Islands (Spain) during the pre-Hispanic stage (3rd–2nd Century BC to 15th Century AD): an overview

Abstract

This paper presents a brief review of archaeological evidence for the impact of the pre-Hispanic population on the environment of the Canary Islands. Prior to human colonisation, the archipelago was an untouched environment with high botanical and faunal biodiversity. The first human settlement can be traced to the early 1st millennium BC; this period of settlement finished at the end of the 15th century AD when the Spanish Crown conquered the archipelago. It has often been assumed that the pre-Hispanic population had little significant impact on the islands' ecosystems. However, abundant evidence for faunal extinctions, deforestation and soil erosion has been recovered from archaeological sites across the islands. This indicates that pre-Hispanic colonisers introduced cultivated plants, opened up the forests to create fields and cut woody vegetation for fuel. They also introduced domestic animals and alien predators resulting in a major depletion of native fauna.     

Temporal changes in Arikara humeral and femoral cross-sectional geometry associated with horticultural intensification

Humeral and femoral cross-sectional properties from three archaeological variants of the Arikara, an American Great Plains Indian tribe, were analyzed for temporal (16th to 19th centuries) changes in long bone architecture, asymmetry, and sexual dimorphism associated with intensification of horticulture during the late protohistoric and early historic periods. There were a number of significant changes in long bone, especially femoral, cross-sectional morphology and asymmetry among females through time that probably reflect increases in the workload necessary to produce surplus crops. Changes in long bone architecture among males are restricted to the humerus and may reflect a greater reliance on firearms. The pattern of sexual dimorphism also changes through time among the Arikara due to a combination of environmental (nutrition and disease) and mechanical factors.     

‘We'll have what they're having’, cultural identity through diet in the English Saxon Period

The roots of the English population lie in diverse cultural origins. Within the second half of the first millennium AD, there were two major migrations, firstly the Saxons in the immediate post-Roman period, and later following the ‘Viking’ incursions of the mid-9th century. This paper considers the visibility of these migrations in the animal economy. Zooarchaeological data from 141 Saxon sites within England were analysed for evidence of diet and animal husbandry. Results indicate that there were signatures specific to native British rural populations in the early Saxon phase, relying largely on a self-sufficient economy, consuming very few wild species or domestic birds. Saxon cultural differences were implied from a number of sites, dependant on the increased importance of cattle in the diet and as culturally symbolic animals signifying status and utilised for trade. There was also evidence for the earliest settlers to have used pigs as a ‘mobile larder’, to provide meat while they established herds and flocks of cattle and sheep. Regional differences were visible in the late Saxon phase, within Wessex and the Danelaw, related to agricultural changes in the midlands and central southern region, and cultural identity, particularly within the heartlands of the northern Danelaw, towards an increase in cattle production.     

Dental Wear and Pathology in the Precolonial Caribbean: Evidence for Dietary Change in the Ceramic Age

This study investigates temporal changes in dietary practices in the Caribbean archipelago during the Ceramic Age (400 BC–AD 1500), through analyses of dental wear and pathology. Some previous studies in the region have suggested that diet and subsistence practices changed over time due to increasing sociopolitical complexity, climate change, or adaptation to island environments rich in marine resources. Both horticultural/agricultural intensification and increased marine focus of the diet over time have been posited, based among other things on faunal and botanical remains, and early ethnohistorical accounts. Local and micro‐regional stable isotope studies of temporal dietary variation have found few indications for change over time, and large regional isotope studies are still lacking. Dentitions from sites throughout the region dating to the Early Ceramic Age (400 BC–AD 600/800) and the Late Ceramic Age (AD 600/800–1500) were analysed in order to assess temporal differences. Intra‐individual rates of wear were calculated using the difference in degree of wear between the adjacent molars and the two groups were compared with principal axis analysis. Caries, antemortem tooth loss, abscesses and dental calculus were recorded per individual and per tooth/socket, and population caries and antemortem tooth loss rates were assessed and compared by age group, tooth class and sex. Comparisons between the two occupation periods revealed significant differences in the rate of dental wear and pathology, indicating a shift in dietary practices over time, coinciding with known social changes. The increase in pathology rates suggests a rise in the consumption of cariogenic foods or preparation techniques that increase cariogenicity. The decrease in rate of wear over time indicates a reduction in abrasivity of the diet. Together these data suggest that there was a growing focus on refined, cariogenic foods, likely horticultural/agricultural produce. Copyright © 2014 John Wiley & Sons, Ltd.     

Pastures lost? A dental microwear study of ovicaprine diet and management in Norse Greenland

The management of ovicaprines by the Medieval Norse farmers in Greenland is explored using dental microwear analysis. Adult and juvenile ovicaprines from Norse contexts in Greenland are shown to exhibit microwear patterns very different to those in modern Greenlandic sheep; while modern sheep demonstrate microwear consistent with low levels of soil ingestion under extensive, low stocking-rate grazing regimes, Norse sheep/goat display striated microwear patterns indicative of high levels of soil ingestion and, potentially, overgrazing. This high abrasive grazing signature is present in the inland region of the Western Settlement from 1150 AD onwards, may be evident in the inland Eastern Settlement from an equally early date and is also detected during the later phases of occupation in the Western settlement (14th and 15th centuries AD). It is argued that these results provide further evidence that maladaptive grazing practices led to a decline in the viability of pastoral farming in Greenland, and, moreover, that overgrazing did not merely occur towards the end of the settlement as a consequence of the worsening climate of the ‘Little Ice Age’ but rather was present in both the Western and the Eastern Settlement from a relatively early date.
