Settlement history, land holdings and landscape change, Eyjafjallahreppur, Iceland

In this paper we focus on a region in south Iceland and assess the confidence with which it is possible to determine the changing patterns of settlement history for a region and relate it to contemporaneous land boundaries. For a geographically coherent group of up to 38 possible farm sites in the northern and western part of Eyjafjallahreppur, south Iceland, the timing of occupation and abandonment is assessed. In addition, boundaries of landholdings, probable status and inter-site relationships are identified. Currently only 10 sites are occupied. There is some uncertainty over the location of the earliest settlements, but after the 11th century, successful principle farm sites such as Dalur, Seljaland and Mörk remain in the same locations. As a result, recent data on landholdings combined with a knowledge of the form of landholding sub-division, offers insights into pre-modern times, with some data relevant to medieval times. An ‘abandoned frontier’ exists in the inland area of Þórsmörk, but abandonment is not restricted to the uplands; it has occurred throughout the region. Most desertion occurred before the cold phases of the Little Ice Age in the 18th century. Overall, much farm desertion can be attributed to landscape destruction as a result of river migration, but it is also biased towards small dependent farms often established for social reasons (such as the property requirement for marriage) and evidently insufficiently resourced for long term success in a changing physical environment

Degrees of success : evaluating the environmental impacts of long term settlement in South Iceland.

This paper focuses on the occupation and landscape history of Dalur and Mörk, two areas of long-term settlement in the Eyjafjallahreppur district of southern Iceland. The aim is to illustrate the importance of evaluating not only farm occupation and abandonment, but also to assess the complexities of the environmental interactions of long-term settlements. Environmental records are assessed using data from 50 sediment profiles, constrained by tephrochronology, located in the farm infields (tún) and outfields (hagi). This record indicates that despite similar outward appearances today, the environs of Dalur and Mörk have experienced different histories of environmental change over the last 1000 years. At least 14 subsidiary settlements were at one time or another established within Dalur, or were dependent on the Church farm there. Ten of these settlements were subsequently abandoned and sediment accumulation rates, a proxy indicator of erosion, remained low, indicating restricted local human impact. We conclude that this illustrates the importance of access and rights to additional resources out with the principal farm. In addition, much of the immediate environs of the main farm site was probably un-wooded at the time of settlement, so the total degree of vegetative change was limited. In contrast, palaeoenvironmental data indicates that the environs of Mörk were extensively wooded at the time of Landnám, but this woodland was rapidly cleared and this was followed by several centuries of landscape instability. In a cultural contrast, the landholdings of Mörk experienced less subdivision with a total of only five dependent farms established across the land belonging to three main farms (all of which had chapels). From the early 10th to 14th centuries there was significantly enhanced erosion within the Mörk landholdings, but this stabilised and the principal farms endured and to form sites of long-term settlement. The ownership of additional resource rights, including woodland further up-valley, may have made the crucial contribution to long term endurance

An over-optimistic pioneer fringe ? environmental perspectives on medieval settlement abandonment in Þórsmörk, South Iceland.

We assess environmental factors that may have contributed to farm abandonment in Þórsmörk, south Iceland. Here farms were established during the initial Norse colonisation of Iceland and abandoned by the 13th century AD. Soil erosion has been identified as a possible factor in this settlement change. This hypothesis is assessed using sediment profiles constrained by tephrochronology in Þórsmörk and the nearby area of Stakkholt. In Þórsmörk, there is evidence for episodes of landscape instability between the 10th and 13th centuries and localised episodes of soil erosion to bedrock that ended before 1300 AD and the onset of the Little Ice Age (LIA) climate changes. This early instability is absent from Stakkholt. Later LIA stability in Þórsmörk contrasts with episodes of instability in Stakkholt. The implication is that Þórsmörk was sensitive to early settlement impacts that lead to extensive erosion. After farm abandonment in Þórsmörk, the surviving woodland was successfully conserved as a valuable source of wood and charcoal for lowland farms where woodland resources had been depleted. Mounting pressure on woodland resources in the 11th -12th centuries could have been an important factor in determining the precise timing of abandonment

Charcoal production during the Norse and early medieval periods in Eyjafjallahreppur, Southern Iceland

Timber procurement and the use of woodlands is a key issue in the Norse and Medieval period in the North Atlantic islands. This paper outlines evidence for the timing and mechanisms of Norse deforestation in an area of southern Iceland which is tracked through the mapping and analysis of charcoal production pits. Precise dating of the use of these charcoal production pits within a Bayesian framework is demonstrated through the combination of tephrochronology, sediment accumulation rates and multiple radiocarbon dates on the archaeological charcoal. The implications for using charcoal as a dating medium for radiocarbon dating in Iceland and the wider North Atlantic are then explored. Finally, the nature of the deforestation and human impact on the environment is placed into the context of the Norse landnám across the North Atlantic

Modeling Historic Rangeland Management and Grazing Pressures in Landscapes of Settlement

Defining historic grazing pressures and rangeland management is vital if early landscape threshold crossing and long–term trajectories of landscape change are to be properly understood. In this paper we use a new environmental simulation model, Búmodel, to assess two contrasting historical grazing landscapes in Mývatnssveit Iceland for two key periods—the colonization period (ca. Landnám, A.D. 872–1000) and the early eighteenth century A.D. Results suggest that there were spatial and temporal variations in productivity and grazing pressure within and between historic grazing areas and indicate that land degradation was not an inevitable consequence of the livestock grazing introduced with settlement. The results also demonstrate the significance of grazing and livestock management strategies in preventing overgrazing, particularly under cooler climatic conditions. The model enables detailed consideration of historic grazing management scenarios and their associated landscape pressures

Provenancing Archaeological Wool Textiles from Medieval Northern Europe by Light Stable Isotope Analysis (δ13C, δ15N, δ2H)

We investigate the origin of archaeological wool textiles preserved by anoxic waterlogging from seven medieval archaeological deposits in north-western Europe (c. 700-1600 AD), using geospatial patterning in carbon (δ13C), nitrogen (δ15N) and non-exchangeable hydrogen (δ2H) composition of modern and ancient sheep proteins. δ13C, δ15N and δ2H values from archaeological wool keratin (n = 83) and bone collagen (n = 59) from four sites were interpreted with reference to the composition of modern sheep wool from the same regions. The isotopic composition of wool and bone collagen samples clustered strongly by settlement; inter-regional relationships were largely parallel in modern and ancient samples, though landscape change was also significant. Degradation in archaeological wool samples, examined by elemental and amino acid composition, was greater in samples from Iceland (Reykholt) than in samples from north-east England (York, Newcastle) or northern Germany (Hessens). A nominal assignment approach was used to classify textiles into local/non-local at each site, based on maximal estimates of isotopic variability in modern sheep wool. Light element stable isotope analysis provided new insights into the origins of wool textiles, and demonstrates that isotopic provenancing of keratin preserved in anoxic waterlogged contexts is feasible. We also demonstrate the utility of δ2H analysis to understand the location of origin of archaeological protein samples

Fjölskyldubrúin : fjölskyldustuðningur með börnin í brennidepli

Geðheilbrigðisþjónustan þarf að miða meira að þátttöku og þörfum fjölskyldna í eigin bata og meðferð (1,2). Þegar börn tilheyra fjölskyldu þar sem annað foreldrið eða jafnvel báðir foreldrar eru að glíma við geðsjúkdóm er barnið aðstandandi(3). Geðrænn vandi foreldra hefur áhrif á daglegt líf allra í fjölskyldunni og er þekktur áhættuþáttur fyrir börn sem eiga allt sitt undir öryggi, vernd og góðum uppeldisskilyrðum. Þunglyndi foreldra og þá sérstaklega móður er talinn vera áhættuþáttur sem getur haft áhrif á líðan og virkni barna frá unga aldri (4,5). Foreldrið, sem eðlilegt er, verður upptekið að eigin vandamálum, líðan og er jafnframt að reyna að skilja sin eigin veikindi til að geta tekist á við þau. Við þessar aðstæður er það algengt að börn búi sér til sínar eigin skýringar sem að miklu leyti eru byggðar á misskilningi m.a. um að þau beri ábyrgð á líðan foreldra sinna. Á undanförnum 20 árum hafa rannsóknir á börnum geðsjúkra gefið okkur gagnreynda þekkingu á því hvernig börn reyna að axla ábyrgð fullorðinna þegar foreldrið veikist og getur ekki sinnt foreldraskyldum sínum (6). Geðrænn vandi foreldra getur því aukið líkur á að börn þrói með sér sektarkennd, skömm, óraunhæfa ábyrgðartilfinningu og vonleysi. Þau geta orðið félagslega einangruð og þróað sjálf með sér geðrænan vanda (7,8,9). Það er hins vegar alls ekki sjálfgefið að öll börn lendi í erfiðleikum eða að erfiðleikarnir leiði til geðræns vanda hjá börnunum (10)
