  1Assessment of the Earthquake Vulnerability of multi-residential Buildings in Slovenia
  Reprint Author E-mail : domen.kusar@fa.uni-lj.si
   Author(s):Vojko Kilar, Domen Kušar
  Keyword(s) :architecture; structural engineering; geography; earthquake safety; earthquake vulnerability; earthquake unsafe buildings; multi-residential buildings; Slovenia
  Abstract:

The paper assesses the earthquake vulnerability of multi-residential buildings in Slovenia, although it is limited to the buildings that were built before 1981, in the time when the earthquake building codes were much less elaborated than today. In the paper, based on the building completion year, buildings are classified into different time periods, which are characterized by important historical events and bigger changes in earthquake building codes. The assessment of earthquake vulnerability is based on the data from the building completion year, number of storeys, prevailing structural material and the year of the last renovation as obtained from the last census of the population, households and apartments completed in 2002. The result is an estimation of the earthquake vulnerability of a building, also because for very similar buildings the earthquake resistance depends on the architectural design of a building, the amount and layout of its structural elements, foundations, soil profile and other influences. In the first part of the paper the multi-residential buildings are divided by age, material and number of storeys. In the second part, the assessment of the earthquake vulnerability of these buildings is divided into three classes: a) probably earthquake unsafe, b) probably earthquake less safe and c) probably earthquake safe. Additionally the earthquake vulnerability assessment is presented geographically by showing the earthquake less safe and unsafe buildings on the maps and charts for different communities in Slovenia. It has been concluded that the earthquake safety of many multi-residential buildings in Slovenia might be questionable, while we have detected also bigger differences between communities

    
   
  2Economic Geographical Assessment of Investments – A Development Factor in Regional Development
  Reprint Author E-mail : marjan.ravbar@zrc-sazu.si
   Author(s):Marjan Ravbar
  Keyword(s) :geography; economic geography; geographical analysis of investments; Slovenia
  Abstract:

The paper presents some geographical characteristics of investment development in the first years of the 21st century, covering at least fragmentarily the gap in Slovenia’s economic geography. In the process we tried to draw attention to the sporadic character and rapid developmental changes in economic geographical events within production systems.
In the paper we focus on the geographical distribution of investments and their impacts on regional development. Special attention is devoted to studying the spatial distribution of investment activities relative to factors such as the amount, development, branch structure, and distribution of the amount of investment that indicate the diversification and development of the economy.

    
   
  3Erosion Processes in Slovene Istria – Part 1: Soil Erosion
  Reprint Author E-mail : matija.zorn@zrc-sazu.si

  Keyword(s) :geomorphology; pedogeography; geomorphic processes; erosion processes; interrill soil erosion; rill soil erosion; Dragonja river basin; Istria; Slovenia
  Abstract:

In 2005 and 2006 intensive measurements were made of various erosion-denudation processes in the Dragonja River basin. The measurements included geomorphic processes in the badlands: the rockwall retreat of steep bare flysch slopes, movements of flysch debris along erosion gullies, and geomorphic processes on talus slopes. At the same time, measurements of soil erosion were made in three different land use areas: bare soil in an olive grove, an overgrown meadow, and a forest. The results are presented in two parts. Part One presents the measurements of soil erosion, and Part Two in the next issue of the journal (No. 49-2) will present geomorphic processes in the badlands.
The measurements of soil erosion made on one-meter-square closed erosion plots south of the village of Marezige revealed that the greater part of the annual erosion was caused by only a few major erosion events. Between May 2005 and April 2006, interrill erosion amounted to 9,013 g/m2 (90 t/ha) on bare soil in an olive grove with an inclination of 5.5º and an average weekly proportion of specific runoff of 23%, 168 g/m2 (1.68 t/ha) on an overgrown meadow with an inclination of 9.4º and an average weekly proportion of specific runoff of 8%, and 391 g/m2 (3.91 t/ha) in a forest with an inclination of 7.8º and 415 g/m2 (4.15 t/ha) in a forest with an inclination of 21.4º with an average weekly proportion of specific runoff of 6% regardless of the inclination. The amount of precipitation during the reference year was slightly below the long-term average

    
   
  4Integrating multi-criteria Models and Geographical Information System for Cemetery Site Selection (a Case Study of the Sanandaj City, Iran)
  Reprint Author E-mail : sedlotfi@yahoo.com

  Keyword(s) :geography; urban land use; AHP; Multi-criteria model; cemetery site selection; GIS; Iran
  Abstract:

The ever increasing urban population growth has created many implications in land use planning in the most of developing countries. Traditional methods of spatial planning are still useful, but they need to be upgraded according to new methodological, technological possibilities and full complexity of spatial planning. The factors which influence the urban structure and its socio-economic life are countless, and so to deal with a huge set of data, Geographic information system (GIS) techniques can help to organize and control the impact of different problems. Urban utilities are the vital elements to provide comfort and amenity for the residents. Clearly in many cases the inappropriate sitting of urban infrastructures has decreased the efficiency and sustainability of the cities. Today GIS as powerful processing means can provide different alternatives for land use planning. One of the most socio-religious urban land uses in Iran is cemetery. Traditionally cemeteries are located in the vicinity of a holy shrine or specified by the local authorities. However, these sites are suitable by the view of people and religious groups but they impose many physical problems such as poor health conditions or accessibility due to the rapid expansion of the city by the population increase. This paper attempts to select a right site for a new cemetery in town Sanandaj, as the old one now has no empty space. The paper applies GIS and Analytic hierarchy process (AHP) techniques to find an appropriate area. The results show that the integrated GIS and AHP model has a high potential to compare different alternatives by investigating multi-criteria models and different factors which are involved in an urban utility site selection

    
   
  5Potential for Tourism in the Demographically Threatened Region of Jurklošter
   Author(s):Maja Topole
  Keyword(s) :rural geography; demography; demographically threatened region; natural and cultural heritage; protected area; tourism potential; local community of Jurklošter; Slovenian Sub-alpine region
  Abstract:

This article examines the demographically threatened region of the local community of Jurklošter in the southeastern part of the Alpine Sava Hills (Posavsko hribovje), part of the municipality of Laško. It draws attention to the natural and social conditions in the region after the Second World War, which led to the steady depopulation of the area. The paper presents the characteristics of the geographical location, settlement, settlements, population and land use, and economic development. It emphasizes the significance of the exceptional natural and cultural heritage as bases for strengthening the role of tourism and recreation, which along with some complementary activities could help reverse negative population trends and provide new sources of income. It deals primarily with natural and cultural motives as important components of the tourism potential of the region

    
   
  6Social Memory and Geographical Memory of Natural Disasters
  Reprint Author E-mail : blaz.komac@zrc-sazu.si
   Author(s):Blaž Komac
  Keyword(s) :geography; geography of natural disasters; geographical theory; historical geography; virtual geography; social memory of natural disasters; geographical memory of natural disasters; human intervention in nature; palimpsest; geographical information systems; environment; landscape
  Abstract:

The article offers a geographical perception of the relationship between social (anthropogenic) and geographical processes including their effects that becomes clearly evident in the case of natural disasters. In modern times, geographical processes are often overlooked as participants in the formation of landscapes. The article considers them from the viewpoint of their visibility in the social sphere, that is, from the viewpoint of the social memory of natural disasters as preserved in oral, written, and architectural accounts as well as other results of human actions in nature. We compare the social memory of natural disasters with the so-called “geographical memory” reflected in the impacts of geographical processes that are visible in the landscape, for example, in features of the relief. The geographical perception of the social and natural elements of the landscape or the imprint of social and geographical processes on the landscape, which can be viewed as a palimpsest, depends on the place and time of observation and on the size and frequency of events. Using selected examples we showed that a quantitative definition is possible of the impact of individual factors on the development of the landscape, which is important for the assessment of geographical processes and for decision-making related to the extent, rationality, and necessity of human interventions in nature. In this framework we also confirmed the importance of the geographical information systems for geography.

    
   
  7Terraced Landscapes in Slovenia
  Reprint Author E-mail : lucija.azman@fa.uni-lj.si

  Keyword(s) :geography; terraced landscape; cultivated terraces; rural geography; agricultural geography; SloveniaReferences
  Abstract:

Slovenia is a country of exceptionally diverse landscapes at the intersection of four major European macroregions: the Alpine, Pannonian, Dinaric, and Mediterranean regions. Terraces, which are a characteristic Mediterranean landscape element, occur in all landscape types, but they vary in terms of density, purpose, and current function. Terraces, which define the most characteristic terraced landscape, are most common in the Mediterranean environment. However, they are also common in Karst-Dinaric landscapes and the wine-growing Pannonian hills, but are more unusual in mountainous Alpine regions, where they occur especially in transition areas to Mediterranean landscapes. Different types of terraces are defined by their purposes: agricultural, viticultural, and fruit-growing. The first type is found across Slovenia, whereas the second and third types are found in hills with favorable climates for cultivating grapes and fruit trees. Agricultural terraces are older; with the declining role of agriculture, increased social mobility, and an ageing and insufficient agricultural workforce, these terraces have lost their former role and their former fields are now almost entirely replaced by meadows. With the exception of the Mediterranean region and some of the Dinaric regions, wine-growing terraces and the less common fruit-growing terraces are the product of modern, mechanized farming, and a different understanding of the quality of vineyard production. This requires greater separation between rows to allow the use of farm machinery between grapevines set further apart
