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.     

Regional polycentricity: an indicator framework for assessing cohesion impacts of railway infrastructures

Territorial cohesion has become one of the main objectives in transport planning. This has fostered the development of assessment methodologies to quantitatively estimate the territorial impact of major transport infrastructures, which are particularly scarce at the intra-regional level. Linked to cohesion, polycentricity has been defined as the best spatial configuration to achieve balanced regions where population and opportunities are distributed among several entities linked by functional relationships. This paper aims to present a methodology to estimate these impacts based on the use of a new regional composite polycentricity indicator. The proposed indicator is tested by comparing the effects of conventional and high-speed railway (HSR) alternatives in the territorial system of a northern region of Spain. This quantitative assessment is a ranking tool for prioritizing rail network alternatives in terms of achieving the most balanced territory, which is especially relevant in countries where HSR networks follow cohesion goals. Our results show that new HSR links should only be complementary to regional railway services, and that the suppression of secondary lines should be avoided if a reduction in polarization is to be achieved.     

Observation and assessment of local economic development with regard to the application of the local multiplier

This contribution deals with the observation and evaluation of the issues of local economic development with a focus on the relatively new method of the local multiplier LM3. The main objective of this article is to evaluate the application possibilities of selected tools for the analysis of local economic development, in order to verify the effectiveness of the methodology of the local multiplier LM3 and to discuss the possibilities of its practical use. This LM3 method is perceived to be one of the convenient methods on how to capture certain components of local economic development. This indicator of the power of local economies is verified within field research in two case studies conducted in the ?umava region in Southwest Bohemia. The added value of this contribution is both methodological and practical. Currently, there exist only very few studies using the LM3 method in the Czech Republic and they do not offer satisfying evaluation of possible broader use of this method in the area of local development in the specific Czech regions. Having summarized two new case studies, this article contributes to the methodological discussion of the LM method and includes concrete practical recommendations for future research and also practical use.     

Multiple inventories and divided archaeology in the West Bank: An assessment of databases in the Etzion Bloc

This paper presents and discusses an assessment of the scope, priorities, and coverage of existing archaeological datasets, via database comparison and on-the-ground re-survey of all accessible known sites in one region of the West Bank, the Etzion Bloc. The main goal of this survey was to assess the current inventories listing archaeological sites in the Etzion Bloc, an area that brings together an interesting range of archaeological and geographical issues that result directly from the Israeli-Palestinian conflict. This database assessment and review of listed archaeological sites included the verification of site existence and the examination of sites’ modern context, accessibility, current condition, potential threats, and the accuracy of their recorded location. The results of this fieldwork demonstrate the importance of keeping data up-do-date, provide suggestions on how to enhance the structure and contents of current inventories, and help prioritize and inform plans for further archaeological fieldwork in this region.     

Seismic Assessment of a Historical Masonry Building in Switzerland: The “Ancien Hôpital De Sion”

This article presents the results of the evaluation of the seismic safety of the Ancien Hôpital de Sion, an important Swiss architectural heritage building, situated in the Canton of Valais, the region with the highest seismic hazard in Switzerland. Three-dimensional Applied Element (AEM) modeling of the whole structure has been performed and validated. The adopted modeling strategy, together with nonlinear dynamic analysis, was able to represent the actual behavior and failure mechanisms typical of complex masonry structures, in addition to a good computational efficiency compared to other available numerical approaches. The local collapse mechanisms have been also studied through a kinematic limit analysis based on rigid block rotation. Both linear and nonlinear approaches have been followed together with the capacity spectrum method. The results provided by the different methodologies have been compared with the aim to provide possible insights concerning a general procedure for the assessment of the safety of such type of structures.     

Student field experiences: designing for different instructors and variable weather

This study compares the field experience and development of sense of place (in this case, human attributed meanings and attachments to the field area) in geoscience students on three separate course sections of a six-day introductory geological mapping field trip. Students stayed in a small farm station within their 4 km² field area, worked in groups of three or four, and produced an individual final assessment. Findings from student interviews and pre-post surveys indicated that there were no significant differences in perceptions of the field trip purpose or sense of place between field trip sections, despite differences in instructor pedagogy and sense of place, as well as varied weather conditions. There were significant increases in student sense of place on all field trips, in contrast with previous work on a “roadside” (regional, multi-site) field trip where no significant change in sense of place occurred. In-field observations and instructor interviews identified key characteristics that supported similar sense of place and experiences on all trips: (1) consistent intended learning outcomes, (2) a carefully selected and immersive field area valued by instructors, and (3) an assessment connected to the landscape/field area with flexibility in its implementation, especially when faced with adverse weather conditions.     

Protecting a ‘Homeric landscape’: The making of the Butrint National Park,Albania

Abstract

This paper will present research on the vulnerability mapping of coastal archaeological sites currently being undertaken in Northern Ireland. The ultimate aim of this research is improve current predictions of where archaeological sites and landscapes will be at risk in the future from coastal erosion. The initial stage of this approach uses a suite of oblique aerial photographs to construct a baseline of eroding locations and coastal geomorphology. The erosion baseline can then be integrated with existing historic environment records to obtain a coarse first-pass archaeological vulnerability assessment. Subsequent stages can then use this assessment to prioritize future mitigation such as field surveys or monitoring exercises, or conduct further refinements of vulnerability classifications by incorporating information on site type and positioning on a local scale.     

ECONOMIC ASSESSMENT OF THE SEISMIC RETROFITTING OF LOW-COST APARTMENT BUILDINGS

When structural retrofitting of buildings is required due to seismic safety considerations, building owners or government officials are faced with a crucial decision whether to demolish and rebuild their buildings, or retrofit them. Simple decisions based on fixed proportions, such as demolish and rebuild if retrofit costs exceed 40% of the replacement cost, may be misleading. A financial analysis should be carried out considering all the revenues and costs of the building during its life time. A low-cost residential apartment building that has a construction cost of $140/m² is selected in this study to represent the vulnerable buildings in developing countries under seismic risk. Life-cycle cost analysis approach is employed to value the rebuild or retrofit alternatives to compare economically. Economic assessment has been carried out for various parameters. It has been found that the age of the building and the retrofit ratio are dominant parameters among the others. The critical retrofit ratio (percent of retrofit cost to initial construction cost) varied from 25% for 40 year old buildings to 67% for 10 year old buildings. It is suggested that economical decisons should not be made simply by comparing the retrofit costs to initial construction costs.
