Good for glaciers,bad for people? Archaeologically relevant climate models developed from reconstructions of glacier mass balance

We present a new climate and vegetation model, and discuss applications with a study of medieval land degradation and settlement abandonment in þórsmörk, Iceland. Existing meteorological data are used as the starting point for modelling glacier snowlines (equilibrium lines), and this is developed to model seasonal snowcover, potential vegetation and growing season. The current status and past fluctuations of glaciers across Iceland provide independent spatial and temporal constraints to the model. In þórsmörk, there was extensive landscape degradation and settlement abandonment in the late Medieval period, with an unclear role for climate change. Modelling of the landscape impacts of a 1 °C fall in temperatures shows that climatically induced degradation through reduced vegetation, growing season, and increased snowcover had limited effects on the once settled area, highlighting the importance of anthropogenically driven change. High resolution modelling offers a significant potential for assessing ‘what if’ questions, and identifying key empirical tests.     

Bronze Age landscape dynamics: spatially detailed pollen analysis from a ceremonial complex

The late Neolithic and early Bronze Age are periods marked by the construction of conspicuous concentrations of ‘ritual’ complexes, used for funerary rituals, seasonal gatherings and communal activities. Understanding the environmental context of monuments may provide detailed insights into relationships between the physical environment and the activities undertaken at individual monuments. Raised burial mounds (barrows) are generally assumed to have been constructed in open landscapes (the so-called ‘landscape openness’ hypothesis) thus rendering them highly visible in the surrounding landscape. This paper seeks to test to what extent vegetation (and in particular openness) around a dense concentration of barrows was actively managed, using three pollen sequences in close spatial juxtaposition to the archaeology. The local vegetation histories, supported by radiocarbon dating, demonstrate spatial differences in vegetation pattern both during the time of monument construction and use (c. 2000–1500 cal BC) and during subsequent periods. They do not support the ‘landscape openness’ hypothesis. This suggests that there is no single ‘blueprint’ for vegetation structure on and around these types of monument complexes. There is no evidence for major restructuring of the landscape during the early Bronze Age. The data describe a major transformation of the vegetation around 1500 cal BC (the Middle Bronze Age) in an area not known for archaeology of this date. This serves to emphasize the role of palaeoecology in augmenting the archaeological record of landscape re-organisation and transformation in prehistory.     

Historic landscape management: a validation of quantitative soil thin-section analyses

The archaeological interpretation of past land management practices can be greatly enhanced through examination of soil thin sections. Features relating to manuring practice are among those key to interpreting agricultural practices. The sources and the processes leading to the distribution of these manure materials may further improve knowledge of the past landscape utilisation. The use of quantitative analyses to examine soil thin sections opens the possibility of considering these relationships between manured areas in greater detail and to extract more subtle spatial and temporal changes in past management. In this study the validation of this methodology has been tested with quantitative image analysis methods used to examine manure inputs to a well-documented historical landscape of Papa Stour, Shetland, where intensive manuring has been practised until the 1960s. By using both historic and ethnographic evidence to validate the image analysis protocol, differences in spatial and temporal distribution are examined for the practices of manuring with both fuel residues and with turf. The validation of the hypotheses expected from ethnographic and historical data that quantitative soils-based evidence allows the definition of variations in manuring strategies and provides a more secure basis from which to interpret manuring management strategies in archaeological landscapes.     

LANDSCAPES OUT OF ORDER: STUDYING THE INNER URBAN FRINGE BEYOND THE RURAL – URBAN DIVIDE

Contemporary accounts of the inner urban fringe tend to focus on the transition from rural to urban land use and rural–urban conflicts, rather than highlighting the landscape at the city edge in its own right. It is argued in this paper that such dichotomous accounts neglect the complexity, values and conflicts of fringe landscapes. The study illustrates that an investigation into the relationship between attempts within spatial planning to design orderly places for urban expansion and the evolvement of places out of order offers a way to analyse landscape transformations at the fringe beyond the rural–urban divide. This approach will offer a multifaceted analysis of the landscape, which in turn will facilitate a more open discussion on land use and values within planning. A theoretical discussion on the interplay between ordered and disordered places is followed by a case study of the interactions between a disordered place and the ambitions within spatial planning to create order. The study has been conducted at the fringe of Burlöv (in southernmost Sweden). By way of conclusion, the findings of the case study are summarized, along with arguments that underline the need for further case studies of fringe landscapes.     

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.     

SPACE,PRESSURES AND THE MANAGEMENT OF THE GREEK LANDSCAPE

Landscapes are the result of the interaction of natural and human factors, with many dimensions; they are part of natural and cultural heritage and an important component of the quality of life. Greece has heterogeneous and mixed landscapes issuing from both geomorphology and the impact of complex human systems. Despite the existence of many and early legislative efforts, Greece has a relatively poor history of spatial planning and landscape has been particularly neglected. The adoption of the European Landscape Convention (ELC) in 2010 provides an updated strategic context for integrating landscape in spatial planning. In this article, we seek to contribute to the discussion of landscape policies and the inclusion of the landscape level in the spatial planning national framework. We identify the dominant landscape types by categorizing landscapes at the national scale with reference to the (combined) presence of three different components: geomorphology, land cover and coasts/islands. Then, we investigate the most important processes of change for each type and link these processes with spatial planning policy. The identification of these dynamics sheds light on current and future trajectories of the changes of Greek landscapes, thus providing challenges for its management in the context of the ELC. The case study concerns the regional level; we focus on Attica, Thessaly, Epirus and the Cyclades and identify the principal characteristics according to the proposed landscape typology.     

Capturing spatial patterns of rural landscapes with point cloud

Over the past few decades, rural landscapes have been the subject of increasing international cultural heritage research, and one of the most important issues under investigation at both theoretical and pragmatic levels concerns how to identify the spatial character of rural landscapes for conservation purposes. This article establishes an innovative approach adopting a cultural landscape perspective with the support of point cloud technologies to capture spatial patterns of rural landscapes. This approach was explored by reference to Tunpu villages in Guizhou, China—these being a specific kind of military fortress settlement. Cultural landscape values and landscape characters of Tunpu villages were identified using historical research and document analysis. Aerial and terrestrial photogrammetry and laser scanning systems were combined to collect and process spatial information at environmental, village, and architectural scales. Point cloud models can quantitatively represent villages' spatial patterns and inform the interpretation of their heritage significance. We conclude that the strengths of point cloud technologies could meet the requirements of rural landscape heritage documentation from a cultural landscape perspective. This mixed‐technology approach could also greatly improve the efficiency and precision of traditional rural landscape documentation, which has the potential to change methodologies applied to rural landscape research and management.     

LEGACIES OF CHANGE: THE SHAPING OF CULTURAL LANDSCAPES IN A MARGINAL MEDITERRANEAN MOUNTAIN RANGE,THE GARRAF MASSIF,NORTH‐EASTERN SPAIN

Human conceptions of landscape have influenced the shaping of landscapes as much as landscape configurations have modelled human perceptions. In this article a new theoretical approach to long‐term cumulative landscape change is tested on the Garraf Massif (Baix Llobregat, north‐eastern Spain). Thanks to its ancient occupation, physical character and location near to the city of Barcelona, the area provides a good illustration of how human‐induced landscape change has shaped new, and sometimes conflicting, landscape perceptions. These perceptions then play an equally active role in altering the previously ‘inherited landscape’ in a long‐term cyclical process that can be studied through the combined use of historical, palaeoenvironmental and archaeological records.

The rise of cultural landscapes

The new interest in cultural landscapes is forcing a reappraisal of concepts of countryside heritage. First the traditional split between cultural and natural values is challenged. Second, modern landscape studies emphasise the subjectivity of landscape assessment, and this is subverting the former tendency to aspire to objectivity in evaluation. The acceptance of ‘associative’ value in landscape is an indicator of this. Modern landscape studies also emphasise the interrelationships between processes and aspects of value, and this is encouraging specialists to communicate across disciplinary frontiers. The desire by ecologists in the mid‐1980s to have cultural landscapes inscribed on the World Heritage list caused a re‐assessment of the World Heritage Criteria, and an initiative by ICOMOS brought this process to a conclusion in 1992. However the reappraisal of concepts of countryside value imply that there are many other philosophical and practical matters still to be resolved.     

GIS,Archaeological Survey,and Landscape Archaeology on the Island of Kythera,Greece

Abstract

GIS and quantitative analysis are used to explore a series of simple but important issues in GIS-led survey. we draw on information collected during intensive archaeological field survey of the island of Kythera, Greece, and consider four questions: the relationship between terracing and enclosed field systems; the effect of vegetation on archaeological recovery; site definition and characterization in multi-period and artifact-rich landscapes; and site location modelling that considers some of the decisions behind the placing of particular Bronze Age settlements. we have chosen GIS and quantitative methods to extract patterns and structure in our multi-scalar dataset, demonstrating the value of GIS in helping to understand the archaeological record and past settlement dynamics. The case studies can be viewed as examples of how GIS may contribute to four stages in any empirically based landscape project insofar as they move from the spatial structure of the modern landscape, to the visibility and patterning of archaeological data, to the interpretation of settlement patterns.     

SHADOWS OF PLANNING: ON LANDSCAPE/PLANNING HISTORY AND INHERITED LANDSCAPE AMBIGUITIES AT THE URBAN FRINGE

The history of vernacular landscapes at the urban fringe is poorly studied, limiting our understanding of the contemporary character of the fringe and our knowledge of the urbanization process. This article argues the necessity of a combined analysis of the legacies of planning and the footprints of former landscape ideals in order to understand the conditions for spatial planning at the urban fringe. After first introducing the methodological use of landscape/planning history, the article focuses on the Swedish discourse on landscape change and landscape planning concerning the urban fringe in the 1930s. Particular focus is placed on the discourse on agricultural landscapes at the urban fringe. The third section of the article presents an examination of the footprints of the ‘landscape convention’ (i.e. an agreement on the meaning of landscape in relation to law and justice) resulting from the landscape discourse of the 1930s. The article argues that the legacy of the 1930s explains some of the difficulties arising when planners of today aim to utilize the farm landscape as a resource for recreation at the urban fringe. The shadow of the landscape discourse of the 1930s also creates difficulties in dealing with peri‐urban landscapes in Swedish planning and Swedish law. With the ongoing discourse on how to implement the European Landscape Convention, such knowledge is particularly useful.     

Human impact and landscape utilization from the Mesolithic to medieval time traced by high spatial resolution pollen analysis and numerical methods

Pollen analysis in relation to archaeological excavations has been carried out by the coast of central Norway to investigate for the first time long-term human impact on the vegetation in this region. A total of 297 samples from eleven archaeological sites and connected bogs/peat profiles reveal the vegetation development from the Mesolithic until today. Principal Component Analysis (PCA) is used to identify and elucidate the development through time and space, and the results of pollen diagrams from bogs are compared to the results of on-site pollen data. Human impact has transformed the vegetation to a varying degree in different time periods. A dense population connected to the shoreline is slightly visible as opening-up of the forest in the Mesolithic, whereas re-use of Mesolithic settlement sites for cultivation and grazing in the Late Neolithic and Early Bronze Age (from c. 2300 cal BC) is clearly documented by palaeobotany but weakly recorded in the archaeological record. Areas for settlement and cultivation are found from the Late Bronze and Iron Ages and pollen analysis contributes to a detailed picture of utilization of the landscape. The investigation shows the potential of combining archaeological and botanical data and analysing several small pollen sequences within an excavation area to reveal spatial patterns in vegetation development and human impact through time.     

The cultural landscape near the ancient city of Tharros (central West Sardinia): vegetation changes and human impact

The evolution of the cultural landscape in coastal western Sardinia is investigated by means of pollen analysis in the Mistras Lagoon sediments, near the ancient city of Tharros, with particular attention to changes in evergreen vegetation and the impact of human activity. The pollen diagram, spanning the time interval from 5300 to 1600 cal BP, documents the influence of man, climate, and geomorphic dynamics on the evolution of a semi-open evergreen vegetation landscape and variations in extent of a salt-marsh environment. Anthropogenic indicators and microcharcoals concur in depicting increased land use coinciding with the Nuragic, Phoenician, Punic and Roman dominations. Pollen data, along with archaeobotanical evidence, suggest a prevailing arable farming economy, vocated to Vitis and cereals exploitation, during the Nuragic phase until 2400 cal BP, replaced since then by a prevailing stock rearing economy. Between 2050 and 1600 cal BP, a less intensive human impact on the landscape is profiled, consistently with the archaeologically documented abandonment of the rural villages in favour of a slow urbanization, experienced by the Sinis territory in Imperial times. The pollen record provides new insights into the history of important economic plants in the Mediterranean, such as Vitis, Olea and Quercus suber. The results of the pollen analysis reveal how the records of these taxa are primarily influenced by the cultural development of the Sinis region and secondarily by dynamics involving the natural companion vegetation.     

Calibration and Test of a Discrete Choice Model with Endogenous Choice Sets

Conventional discrete choice models assume implicitly that the choice set is independent of the decisionmaker's preferences conditional on the explanatory variables of the models. This assumption is implausible in many choice situations where the decisionmaker selects his or her choice set. This paper estimates and tests a discrete choice model with endogenous choice sets based on Horowitz' theoretical work. To calibrate the model, a new probability simulator is introduced and a sequential estimation procedure is developed. The model and calibration methods are tested in an empirical application as well as Monte Carlo simulations. The empirical results are used to test the theory of endogenous choice sets and to examine the differences between the new model and a conventional choice model in parameter estimates and predicted choice probabilities. The empirical results strongly suggest that ignoring the endogeneity of choice sets in choice modeling can have serious consequences in applications.     

Cultural landscape protection in Australia: The Wingecarribee Shire study

Abstract

The concept of cultural landscapes as remarkable windows onto the past, and rich historical documents that can be read has gained increasingly wide acceptance in Australia over the past few years. Allied to this, and informing it. is the way in which landscape as a cultural construct plays a major role in attachment to place and sense of Australianness. The understanding of cultural landscapes as a setting where human history is on display is a community movement as well as a professional one. This paper reviews one particular study which focused on heritage evaluation of an historic rural landscape and moves for its protection.     

Alexander von Humboldt's invention of the natural landscape

Landscape took on a new meaning through the new science of plant geography of Alexander von Humboldt (1769–1857). In the seventeenth and eighteenth centuries, “landscape” was foremost a painterly genre. Slowly, painted landscapes came to bear on natural surroundings, but by 1800 it was still not common to designate sites as “landscapes.” Humboldt looked at plant vegetation with a painterly gaze. Artists, according to him, could suggest in their work that an abstract unity lay hidden underneath observable phenomena. Humboldt projected painted landscapes on nature and found its ecological unity. By doing so, he ultimately stripped the concept of landscape from its primary visual meaning.     

Investigating shellfish deposition and landscape history at the Natia Beach site,Fiji

The relationship between environmental variation and subsistence practices is a central point of discussion in much Oceanic archaeology. While human predation can significantly reduce prey populations, environmental variation also contributes to reductions in prey abundance, possibly leading to increased human competition and resource scarcity. At the Natia Beach site, Nacula Island, Fiji, geoarchaeological evidence suggests that coastal progradation began soon after initial occupation of the coastal plain. Additionally, at approximately 650 BP a marked increase in clay and silt deposition occurred. Changes in coastal geomorphology may be explained by landscape response to regional Mid-Holocene sea level fall combined with human induced soil erosion due to upland settlement. Smaller scale environmental changes associated with climate variability may have also played a role. Additionally, landscape change appears to have had a measurable impact on local nearshore mollusks that are sensitive to high levels of water turbidity. Minor evidence of human exploitation is observable in this shellfish assemblage, although changes in predation pressure may have allowed shellfish populations to recover. Increased ceramic diversity and fortified settlements also appear at approximately 650 BP on Nacula and other parts of Fiji. The suite of changes at Natia may be explained by processes of regional and local environmental changes, and human adaptation in terms of subsistence, spatial organization, and competition.
