Agricultural slope management and soil erosion at La Laguna,Tlaxcala, Mexico

Several superimposed systems of agricultural terracing are preserved at the archaeological site of La Laguna in central Mexico. Excavations uncovered complex stratigraphic sequences of terrace fills and colluvial deposits. Their chronology was established by radiocarbon, optically stimulated luminescence (OSL), and the presence of diagnostic features and artifacts. The Formative occupations of the site (ca. 600–400 BC and 100 BC–AD 100) resulted in severe erosion and exposure of indurated subsoil horizons. In the Middle to Late Postclassic (AD 1150–1520) stone-walled terraces were built to recover the degraded slopes for cultivation. Renewed reclamation works have been undertaken since the Colonial period, eventually taking the form of sloping-field terraces with berms planted in maguey. The reconstructed sequence of local land use underscores the risks of dating agricultural features by association with sherd scatters, as well as the complexity of the relationships between demographic variables, agricultural intensity and terracing.     

Early Middle Ages Houses of Gien (France) from the Inside: Geoarchaeology and Archaeobotany of 9th–11th c. Floors

ABSTRACT

At Gien (France), indoor floors from early Middle Ages occupation (8th–10th c. AD) are very well preserved, providing a new reference for archaeological investigation in northern France. This site is located on an outcrop, 20 m above the Loire valley, where a 15th c. castle stands now. The medieval occupation combines high-status houses with crafting and agricultural areas. They constitute a new urban nucleus, which grew 2?km east from an ancient Roman settlement. During the rescue excavation, four buildings of different status were sampled and studied using an integrated approach, combining stratigraphy, micromorphology, chemical, macro-remain and phytolith analyses. Micromorphological investigations helped to identify 74 built floors, from 0.5 to 150?mm thick, made with transformed local clay or imported silty earth. Mineral floors were covered by vegetal ones, consisting of crop processing refuse. These litters include an abundance of phytoliths and some seeds, both produced by cultivated cereals, which were processed in situ, such as Triticum durum, Secale cereale and Hordeum vulgare. The refuse above the mineral and vegetal floors were trampled. They were produced not only by domestic activities, such as cooking and eating, but also by metallurgic activities and animal husbandry. The investigation of a contemporary pit indicated that, despite the large amount of refuse, floors were well maintained and regularly rebuilt. The spatial distribution of waste indicated that a single space could be dedicated to several activities, which were not necessarily separated by new floors. Moreover, the total absence of bioturbation allowed the study of a stage of dark earth formation, by comparing it to the contemporaneous mechanical disturbance of a part of the strata which occurred when building new floors. All these results give new evidence of the richness and the complexity of the early Middle Ages town, in addition to help identifying the activities which could take place in early castral areas.     

Flaked-Stone Artifacts in Greece during the Historical Period

Abstract

The evidence for historical flaked-stone artifacts in Greece is summarized. In recent years a number of such artifacts have been recognized in stratified deposits of the early Iron Age, the Protogeometric, Geometric, and Classical periods. Historical flaked-stone artifacts were probably used for making agricultural tools and were low-cost substitutes for metal. The evidence indicates that an ancient Greco-Roman flaking tradition may bridge the gap between the latest Bronze Age tradition and the gun-flint and threshing sledge flint knappers of recent times. An economic model of innovation is used to explain the use of stone tools after the introduction of metal.     

Identification and assessment of secondary refuse aggregates

Secondary refuse contains a wealth of information on the people who generated it. This article identifies some means by which archaeologists can identify and characterize secondary refuse aggregates — localized, high-density deposits of artifacts that have been discarded away from their place of use. A variety of studies of archaeological deposits — from prehistoric and historical archaeology, ethnoarchaeology, and modern material culture studies — provides hypotheses and a comparative database for discussion. I suggest that socioeconomic and demographic factors operating in a society greatly affect the composition of secondary refuse aggregates and propose some hypotheses regarding the directions and magnitudes of these relationships.     

Mossland Reclamation and Refuse Disposal in the Manchester area in the nineteenth century

Abstract

Mossland reclamation is a distinctive feature in the formation of the English cultural landscape. Most mosslands were reclaimed purely for agricultural purposes. Manchester's growth in the later nineteenth century brought acute problems of refuse disposal. Carrington and Chat Mosses were acquired by Manchester Corporation for the dumping of that refuse. Between 1886 and 1910, the two mosses absorbed 20 per cent of all refuse. At the same time, but originally less important these two mosslands were converted into agricultural land. The reclamation of Carrington and Chat Mosses is a fine example of the influence of towns in the nineteenth century on the agricultural development of their hinterlands.     

An early Iron Age assemblage of faience beads from Ashkelon,Israel: chemical composition and manufacturing process

The microstructure and chemical composition of eight faience beads from an early Iron Age (12th century BCE) assemblage found in the ancient city port of Ashkelon (Israel) are determined by means of FTIR spectrometry, pXRF, microRaman and SEM-EDS analysis. The results are compared with published data of Egyptian and Near Eastern artifacts. Each sample exhibits a hue which is obtained by adding a specific colorant to the glazing mixture. A new gray chalcopyrite-manganese-based colorant was identified. Cementation glazing was most likely used in the manufacturing process of the specimens analyzed, except for the blue bead, which is an Egyptian blue frit. The results suggest that these objects represent a unique assemblage, quite different from contemporary Egyptian and Near Eastern materials, and provide new information regarding the Iron Age faience evidence in the southern Levant.     

The chalcolithic period in the Levant

The Levant of the fourth millennium B.C. was scattered with numerous small farming communities. The agricultural activities were based on growing barley, wheat, lentils, and fruit trees. This was accompanied by raising sheep-goats, pigs, and cattle and occasionally using marine resources. The architecture and the thick accumulation of debris loaded with pottery refuse indicate that the sites were sedentary and occupied for long periods. The social organization of these communities does not seem to have been very complex. The evidence argues against the existence of hierarchies and high-status social units that had the power to dominate and permanently regulate production and distribution. The evidence of religious activities also indicates that a priesthood, if it existed, was not dominant in the regulation of social and economic activities. The rapid cultural changes in the Levant during the late fourth and early third millennium were probably caused by the impact of the events in Egypt and Mesopotamia. The local modifications were readjustments to the large-scale changes in the Near East which influenced the rural and provincial Levantine Chalcolithic societies.     

Ancient Maya Agricultural Installations and the Development of Intensive Agriculture in NW Belize

Abstract

Archaeological study of the spatial arrangement of agricultural features such as terraces and berms yields insight into the scale, mode, and tempo of farm production and the social organization of farming communities. Data from five regions of the Maya lowlands where such features have been extensively documented demonstrate the range of strategies employed by the ancient Maya to organize agricultural production. In some previously studied regions of the lowlands, spatial patterns suggest centralized management of farmland by state institutions, while in others a smallholder strategy seems evident. In the Río Bravo region of NW Belize, the organization of agricultural labor centered neither on the state nor on the individual farm family, but on the farm community. Moreover, the incremental conversion of open lands to terraced agricultural fields was part of a long-term interactive sequence of environmental change and human response over centuries of occupation. This sequence demonstrates that the ancient Maya not only adapted to a degraded environment but used it to their advantage, developing new technologies that were successful for several centuries prior to their ultimate failure. The agricultural history of the lowland Maya demonstrates that indigenous systems of resource management in fragile environments such as the tropics were not always deleterious. The innovations and successful adaptations of ancient farmers should also be recognized.     

Coupling Hydrotoponymy and GIS Cartography: A Case Study of Hydrohistorical Issues in Urban Groundwater Systems,Porto, NW Portugal

The aim of this multidisciplinary study is to retrospectively examine hydrohistorical issues, namely hydrogeographic, hydrotoponymical and hydrogeological features, in order to assess the evolution of the Porto urban groundwater system (NW Portugal). To achieve these goals, the comparison of two main field inventories in a large urban region was performed by (i) historical mapping of sources and groundwater data from scientific reports spanning the late 17th century to the early 20th; and (ii) hydrogeologic and hydrotoponymical field inventory performed under current conditions. These field inventories permitted the location of springs, dug wells, fountains, public washing places and underground water galleries, which collected groundwater to supply the population of Porto until the early 20th century. This study also allowed the development of a hydrotoponymical classification for urban areas and a field hydrotoponymical inventory data sheet. This research integrated several techniques based on historical hydrogeography, hydrogeology and urban geosciences. The results of the field inventories were combined into both a database and a Geographical Information System (GIS) platform. This unified methodology allowed a cross‐check and analysis of several levels of information, namely hydrotoponymy, hydroclimatology, hydrogeology, structural geology and geomorphology. This perspective led to an assessment of the evolution of the quality of water resources in large urban areas over time. In addition, the role of hydrotoponymical features is presented in order to support the hydrogeological conceptual model for large urbanised areas.     

The palaeogeography and Neolithic archaeology of Herm in the Channel Islands

Abstract

The small Channel Island of Herm combines several distinct habitats ranging from steep rocky coasts and a rolling upland plateau in the south to a dune-fringed sandy lowland in the north. Where upland and lowland meet, a line of megalithic tombs constitutes the island’s most striking archaeological feature. Four seasons of fieldwork (2008–2011) have sought to determine the environmental history of northern Herm since the last glacial period and to place the tombs within the broader context of Neolithic activity. A series of trenches and boreholes has revealed the changing morphology of the prehistoric land surface that lies buried beneath the extensive deposits of aeolian sand that cover this part of the island. Results indicate that much of the lowland plain was initially occupied by a shallow marine inlet that was cut off from the sea and progressively infilled starting in the 4th millennium b.c. Pollen and soil sequences reveal how the wooded early Holocene landscape around the edges of this inlet was steadily degraded by human impact and climate. Traces of settlement and cultivation (plowmarks) suggest the megalithic tombs were situated within an agricultural landscape. This finding has relevance for theories that have proposed that islands were favored places for burial by communities visiting from the neighboring mainland. Herm was a locus for settlement and farming as well as for burial during the Neolithic period.     

Microfossil evidence of land-use intensification in north Thailand

Palaeo-environmental data from accumulated lake sediments at Phayao, northwest Thailand, provide a record of vegetation and environmental change from approximately 20,000 years Before Present. This is an important region archaeologically, with claims in the 1970s for an ‘early’ transition to domestication having arisen from a number of cave sites. Multiple indices are used to determine if people had an observable impact on the natural environment, and to determine the timing and magnitude of impacts associated with the development of agricultural land use in the region. An initial increase in sedimentation rate is apparent from ca. mid-2nd C AD. Changes in phytoplankton concentrations are apparent from the late 3rd C AD, and evidence for initial forest disturbance is apparent from the 5th or 6th C AD, with impacts becoming more severe over time to reach a pre-modern maximum in the 11th to the 13th C AD. Changes in agricultural practices are apparent during the 14th C AD, with an increased emphasis on rice agriculture and incipient management of the regenerating forests. Based on these data we suggest that agricultural intensification in the early part of the 1st millennium AD destabilised catchment slopes, through clearance of dryland vegetation and swidden agriculture. There is no direct evidence for the impacts of earlier peoples on the vegetation of the area, which we take to indicate that agricultural intensification was later here than in the lowlands to the east and south.     

Constructing Community Through Refuse Disposal

Unlike archaeologists working in Europe, Southwest Asia, and North America, Africanists have been slow to explore links between culturally structured, everyday practices, and refuse disposal, remaining inclined to view all “midden” accumulations as undifferentiated deposits. However, African ethnographic cases and archaeological researches elsewhere demonstrate that such accumulations can be highly selective and culturally structured compositions. This paper reviews examples that have shown cultural structure in the disposition of spent items. It then explores African ethnographic and archaeological cases, one from Niger and three from East Africa, in which handling of culinary artifacts and products may reveal links between household and community through habitual acts of refuse placement.     

Oldowan behavior and raw material transport: perspectives from the Kanjera Formation

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.     

Eighteenth-century Copenhagen viewed from a refuse dump

Abstract

The excavation of a town refuse dump in Copenhagen has recovered a remarkably rich and varied assemblage of artefacts including ceramics, glass, animal bones, feathers, textiles, gloves, woollen socks, silk stockings and shoes. They were deposited c. 1750–65, but include many objects dating from the early years of the 18th century. Because the deposits were waterlogged, various unusual types of organic evidence were preserved. This paper gives an introduction to the site and its material, and outlines some of its research potential.     

The Roman Well at Piddington,Northamptonshire, England: an Investigation of the Coleopterous Fauna

Abstract

This report presents the entomological evidence obtained from 4th century fills of a Roman well at Piddington, Northamptonshire. Analysis of the Coleoptera remains was restricted to one sample from the lower fill. A large fauna suggested an open, dry environment with areas of vegetation and accumulations of occupation debris nearby. The deposit was formed through a variety of mechanisms including accidental incorporation, natural deposition and possibly the deliberate dumping of refuse.     

The Landes de Gascogne (southwest France): periglacial desert and cultural frontier during the Palaeolithic

During the last glacial period, a large part of the Aquitaine basin (southwest France) was a periglacial desert comprising coversands with low-relief dune fields surrounded by loess accumulations. OSL and radiocarbon dates show that the phase of maximum sand deposition coincides with Marine Isotope Stage (MIS) 2. Peats and gleyic palaeosoils intercalated within the sands at some sites indicate that vegetation cover was able to develop locally during short events, possibly D–O interstadials, due to raised groundwater levels in interdunal depressions. Few Palaeolithic sites have been discovered in the coversand area in contrast to the peripheral loess region. Systematic survey along a future highway corridor demonstrates that this paucity of sites is not the result of insufficient survey nor deep site burial, but rather reflects an archaeological reality. This strongly suggests that the sand area was not attractive for hunter–gatherer populations due to its reduced levels of water resources, and available vegetation and animal biomass. The distribution of cultural markers such as art items and projectile points also shows that the coversand area probably acted as a barrier separating two different cultural sub-areas, one in the Pyrenees and Cantabria, the other in the Périgord. As a consequence, the commonly accepted view that southwest France, as a whole, served as a refugia during the cold and arid phases of the Pleistocene should be replaced by a more complex one that reflects the fact that a large part of the territory was almost unoccupied and that human populations were concentrated along alluvial valleys.     

Inca and colonial settlement,coca cultivation and endemic disease in the tropical forest

A configuration unfolds from early colonial chronicles, the archaeological record and epidemiological evidence that infectious disease was a critical factor in constraining durable pre-Hispanic settlement in the Amazon forest. The Incas' main interest in the wet tropical valleys beyond the mountain front, particularly those northeast of Cuzco the capital, was to grow coca. Quest for the sacred leaf justified intrusions into a hyperendemic zone of mucocutaneous leishmaniasis, a complex protoxoal disease carried by sand flies that results in dermal lesions and grotesque necrosis of the face. In an effort to avoid this disfiguring disease, the Incas carried on trade relations with forest tribes, subjugated some of these tribes to clear the forest for them, and shifted people from analogous climates elsewhere. The most important mechanism was to control the length of the work period of coca labourers from the highlands. Traditional vertical migration of Andean natives and siting of pre-Conquest dwelling sites largely above the zone of leishmaniasis contraction suggest an ancient geographical pattern of disease avoidance. After the Conquest, disease mortality was very high, as Spaniards expanded coca cultivation but disregarded many of the indigenous safeguards. Adjustments to an insalubrious yet compelling environment are more persuasive than agricultural limitations in understanding the deep-seated past aversion of highland Indians to sustained occupance of the selva.     

Changes in regional settlement patterns and the development of complex societies in southeastern Shandong,China

Around the globe, archaeological settlement pattern survey has brought a new spatial, diachronic, and theoretical vantage to the study of early civilizations. This paper provides a new perspective on the rise and reorganization of complex societies in northern China through the synthesis of 11 years of systematic regional survey in southeastern Shandong Province. Based on our surface findings, we suspect that the agricultural colonization of this coastal region occurred primarily during the later half of the Neolithic and was rapidly followed by the development of a four-tiered settlement hierarchy with two primary centers during the Early Longshan period. We also document the reorganization of this regional system during the Bronze Age, and the eventual political integration of this study area under polities centered to the west (and outside the region surveyed). We argue that southeastern Shandong was not merely a backwater or periphery throughout its history, particularly in regard to the Early–Middle Longshan periods when there were centers of great size. Through our long-term and broad-scale perspective, we provide new evidence of how complex societies arose and changed over millennia in northern China.     

The Writing on the Wall: The Concealed Communities of the East Yorkshire Horselads

This paper examines the graffiti found within late 19th and early 20th century farm buildings in the Wolds of East Yorkshire. It suggests that the graffiti were created by a group of young men at the bottom of the social hierarchy—the horselads—and was one of the ways in which they constructed a distinctive sense of communal identity, at a particular stage in their lives. Whilst it tells us much about changing agricultural regimes and social structures, it also informs us about experiences and attitudes often hidden from official histories and biographies. In this way, the graffiti are argued to inform our understanding, not only of a concealed community, but also about their hidden history.     

More than Meets the Eye: A Preliminary Report on Artifacts from the Sediment of Site 31CR314, Queen Anne's Revenge,An Eighteenth-century Shipwreck Off Beaufort Inlet,North Carolina

The excavation of 31CR314, an eighteenth-century shipwreck identified by the North Carolina Department of Cultural Resources as Queen Anne's Revenge, off Beaufort, North Carolina, produced innumerable small artifacts from the sediment. In addition to objects of metal, glass, lithics, wood, and bone, thousands of microartifacts were recovered from the dredge spoil using a sluice and screen system. These microartifacts provide another layer of evidence, corroborating the current hypotheses regarding site formation processes, namely that the site represents a grounded vessel exposed to repeated periods of scour and reburial over nearly 300 years. The evidence provides a model for the formation of shipwreck sites in similar dynamic sand bar environments, where such sites would be exposed to the filtering of light artifacts, and the potential downward migration of artifacts into the substrate. Work at the site has shown that the extricating microartifacts from the sediment, although time-consuming, can make a significant contribution to understanding site formation processes.
