Waterfalls,science and aesthetics

Waterfalls and rapids are a subject of study by scientists and scholars from a variety of academic and professional backgrounds. Unlike cave research, known as speleology, which also involves many different disciplines, the study of waterfalls is not generally regarded as a distinct branch of knowledge. Long neglected as subjects of research, waterfalls have received considerable attention since the 1980s. This paper traces the study of waterfalls from the late eighteenth century, a period when both a scientific and an aesthetic interest in landscape developed in Europe, to the present. The work of geographers, geologists and others who studied landforms and landscapes is examined, with particular attention to those who expressed a special interest in waterfalls, notably Alexander von Humboldt. The study argues that the scientific and aesthetic approaches to landscape research are not incompatible and supports the view that both are necessary for a full understanding and appreciation of the environment in which we live.     

Winners and losers. Turnout,results and the flows of vote

Not all general elections can be considered as being equal: some are placed in continuity with the previous political phase and therefore do not change the most relevant features of the party and political system; others, however, tend to represent a watershed between distinct political phases. Without a doubt, the 4 March 2018 Italian general elections belong to the latter category. This article analyses those same elections from three points of view: firstly, it reconstructs and explains electoral turnout, both following a long-term diachronic perspective, as well as comparing the various areas of the country from a territorial point of view. Secondly, similar diachronic and territorial comparisons are conducted with respect to electoral results, so as to clearly identify winners and losers of the 4 of March. Finally, it presents flows of votes in thirty-eight different territorial contexts (cities or electoral constituencies): in this way, it is possible to precisely reconstruct the reasons behind the ‘electoral earthquake’ of 4 March 2018.     

A Comparative Analysis of the Late Woodland–early Mississippian Settlement Landscape in Northern Georgia

To understand the development of complex socio-political phenomena, we need to study not just the origins of central places, but also their emergence. This can be accomplished by taking an historical perspective where we position ourselves before the occurrence we wish to study. Data from the Georgia Archaeological Site File are presented to explore the Late Woodland and Early Mississippian (ca. A.D. 600–1,100) settlement landscape which contextualized the emergence of two prominent Mississippian mound centers: Macon Plateau (also known as Ocmulgee) and Etowah. Our results suggest that the Etowah River valley supported a denser population who had formed attachments to particular points in the landscape compared to the region surrounding Macon Plateau during the Late Woodland to Early Mississippian transition. These social landscapes provided different contexts for the origins of each Mississippian center and influenced later trajectories of cultural development and settlement in each region.     

2001-2008年无锡市土地利用景观格局变化分析

无锡市作为位于长江三角洲地区的核心地域,2000年实施新城市化战略以来城市化水平大幅上升,但对这一时期无锡市土地利用景观变化的研究相对较少。本文从景观生态学的角度研究无锡市2001-2008年间的土地利用景观变化,发现无锡市的土地利用变化速率较快,且递减最快的为耕地,而递增最快的为建设用地及园地;无锡市2000年之前景观格局基本构型以大斑块为主,景观格局较为单一,但2001-2008年该地区剧烈的人类活动使得这些大斑块发生破碎化,导致不同景观类型的斑块数量不断增加,各类用地所占比例的差异逐步减少。总体上看,无锡市的景观多样性在增加,景观优势度在减少。     

Contributions of GIS and Satellite-based Remote Sensing to Landscape Archaeology in the Middle East

This article explores the coevolution of landscape approaches and geospatial tools in Middle Eastern archaeology. From the first aerial reconnaissance programs, archaeologists recognized the value of a view from above to address overarching human–environmental questions that underpin regional historical narratives. The diversity and density of visible remains in the landscape of the Middle East has required an integrative approach, encompassed in the perspective of landscape as a static artifact, landscape as built features, landscape as a system, and landscape as a dynamic construct, which cuts across modern political boundaries. Recent advances in geospatial tools and datasets have enabled archaeologists to make significant progress on four long-standing questions of how to (1) best document and manage rapidly disappearing ancient landscapes, (2) understand landscape formation processes, (3) identify and interpret economic, environmental, and social influences that result in long-term settlement and land use patterns, and (4) recognize and contextualize the interplay between environment and human agency in the evolution of ancient economies and transformations in socio-organizational complexity.     

Geoarchaeological perspectives on paleolandscapes and regional subsurface archaeology

This paper explores geoarchaeological approaches to regional-scale research in dynamic landscapes. Landscape element, a spatial concept from landscape ecology, and the archaeological notion of place are integrated with geomorphological models of landscape evolution. A distributional or non-site approach to the subsurface archaeological record is argued to be most consist with a dynamic view of landscapes. Regional geomorphological studies are shown to be crucial, given the volume of sediment that needs to be searched, in developing efficient subsurface sampling strategies. Various subsurface recovery techniques are reviewed, including the potential use of microartifacts to increase the effectiveness of small bulk samples in sampling the buried archaeological record.     

There's more to landscape than meets the eye: towards inclusive landscape assessment in resource and environmental management

Consideration of aesthetic values in resource and environmental management in North America emerged in the 1960s. It soon became enshrined as 'visual resource management', which emphasized a singular visual notion of aesthetics and an expert‐based approach to assessment. This paper challenges this dominant view. An empirical research study is presented in which a broader conceptualization of the landscape aesthetic and a participatory methodology for assessment were developed and used to explore the landscape experiences of inhabitants of the Cariboo region of British Columbia. Themes, categories and ideas of landscape experience grounded in participant perspectives revealed a richness of landscape and can be seen as an opportunity to supplement and enrich current landscape assessment and 'visual' management. More importantly, this conceptual and methodological reorientation in understanding landscape aesthetic sensibilities both reflects and supports the shift in current thinking within resource and environmental management more generally, from technocratic, state‐centred, expert‐based approaches to locally responsive (place‐based), participatory and inclusive approaches for dealing with environmental concerns and resource‐development issues .     

On the So-Called Anthropogenic Landscapes

A Leningrad physical geographer, who is an advocate of the natural landscape school in Soviet geography, offers a critique of the school of anthropogenic landscape science favored by F. N. Mil'kov of Voronezh University and others. Landscapes, in the critic's view, are natural formations produced by physical cause-and-effect relationships among their natural components, and no basis is found for the development of a theory of anthropogenic landscapes that reflect the impact of human activity and minimize the role of natural elements. The author questions whether man is in fact capable of creating landscape in the literal sense and whether this can be accomplished by merely modifying a single natural landscape component. Further investigation is urged to establish the real role of engineering structures and agricultural activities in the landscape and their place within the system of natural linkages within the landscape. This line of investigation should then lead to study of the structure of landscapes that have been modified by man and to an understanding of a sequence of landscape succession, including man-induced and reconstructed variants.     

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.     

Creating authentic ‘glacial’ landforms from waste materials: Two UK case studies

This paper describes two case studies of hills of waste material in the UK that have been specifically conceived to replicate glacial landforms. In one case a spent oil‐shale tip ('bing') and municipal waste dump in West Lothian has been remodelled and restored in the form of a local glacial crag‐and‐tail. In the other, a municipal waste disposal landraise hill in Lancashire has been designed to resemble the local drumlins. An assessment of the geomorphological authenticity of the landforms is made and it is concluded that the involvement of glacial geomorphologists in such projects is important if convincing and authentic outcomes are to be achieved. Adherence to landscape principles and attention to detail can pay dividends in winning public support, in achieving cost savings, and in securing successful after‐uses.

Bourdieu, rational action and the time-space strategy of gentrification

This paper proposes gentrification as an example of class habitus adjusting to a new field via a time-space strategy that involves conscious rational coordination of class agents on a new aesthetic 'focal point'. This approach suggests: (1) a much greater role for conscious rational processes in both the intentional and intuitive processes of class reproduction; (2) an understanding via gentrification of the symbolic significance of time-space in class processes; (3) the significance of individual class agents in the process of gentrification; (4) a view of gentrification that gives greater prominence to working-class taste and habitus.     

Patterns and Determinants of Historical Woodland Clearing in Central‐Western New South Wales,Australia

We consider the history of woodland clearing in central western New South Wales, Australia, which has led to the present highly cleared and fragmented landscape. A combined approach is used examining available historical land‐use data and using regression analysis to relate the pattern of cleared and wooded areas in the recent landscape to environmental variables, taking into account the contagious nature of clearing. We also ask whether it would be possible to apply a simple simulation modelling approach to reconstruct a credible historical sequence of clearing in the study area. The historical data indicate that annual clearing rates have varied substantially in the study area and selective tree removal (ringbarking and thinning) has been common. These findings make it unlikely that a simple simulation approach would replicate the spatial and temporal sequence of woodland loss. Our regression results show that clearing patterns can be related to environmental variables, particularly annual rainfall and estimated pre‐European vegetation type, but that patterns are dominated by contagion.     

Reconstruction of Caprine Management and Landscape Use Through Dental Microwear Analysis: The Case of the Iron Age Site of El Turó de la Font de la Canya (Barcelona,Spain)

This paper presents the results of a pilot study using dental microwear analysis on 23 sheep and goat teeth dated to the 6th century BC from the Iron Age site of El Turó Font de la Canya (Barcelona, Spain). This study aimed to reconstruct livestock management practices and landscape use. The dental microwear pattern indicates that sheep and goats could have been grazing in the same area where vegetation was composed of shrubs, bushes and non-graminaceous plants on an eroded landscape, although additional supplies of fodder cannot be excluded. This scenario is compatible with the archaeological and palaeoenvironmental data which suggest a possibly increased territoriality, land degradation and an increase of woodland clearance during Iron Age in the North-east of the Iberian Peninsula. Furthermore, we applied two recent microwear approaches which provide more information about mortality events and the possibility of distinguishing between an intensive and extensive management. This paper demonstrates how this method can be used to better understand animal husbandry practices and landscape use in Late Prehistory.     

SOCIAL ORGANIZATION AND HUMAN SPACE IN NORTH‐EASTERN IBERIA DURING THE THIRD CENTURY BC

By using GIS (Geographical Information System) visibility analysis, the visual surveillance of, and ways in which people engaged and experienced, an Iberian landscape north of Barcelona during the third century BC are explored. The study of visual surveillance from the hillforts that dominated the area is understood as a means to address issues of social structure and hierarchy. How Iberian people might have viewed and rationalized their world, which is an issue that has so far not been addressed within the theoretical approaches that currently characterize this area of Mediterranean archaeology, is explored here for the first time. Emphasis is placed on people's sense of place and on hillforts' prominence. Visibility analysis indicates a highly structured society, where each hillfort might have primarily controlled given zones of the landscape and might have informed others about events taking place there through an integrated visibility network. Whilst hillforts appear to have been sited according to the view that they offered, they do not seem to have been intended to maximize their own visual impact. Social and experiential approaches compellingly coincide to suggest a subdivision of this society between mountain and coastal communities in both practical and perceptual terms.     

Some Thoughts on the Subject of Historical Geography

A geographical historical geography, concerned with the history of development of the landscape, is distinguished from the historian's historical geography, dealing with the geography of countries and regions in the past and the history of development of cities and transport routes. The aim of the geographer's approach to historical geography is to characterize changes in the natural environment during historical times, to map landscapes from the point of view of their evolution and to classify and regionalize them on the basis of genetic principles. For this purpose, historical geography is to be distinguished from paleogeography, which should be limited to evolution of the landscape in prehistoric times.
