  • Modelling of high-mountain relief
  • Indicator ; Mountain ; Patterned ground ; Periglacial features ; Permafrost ; Poland ; Slope deposit ; Slope dynamics ; Tatra Mountains
  • The aim of this paper has been to discuss, by reference to the Tatra Mountains, the relationship between landform development and the presence of permafrost in mountains in which the latter is only present in isolated patches. Thus the slope

  • The influence of factors of the socio-geographical structure of mountain farms in Slovenia upon farm succession statuses and decisions
  • Agriculture ; Farm ; Methodology ; Mountain farming ; Perception ; Slovenia
  • This paper discusses the influence of single factors of the socio-geographical structure of mountain farms in Slovenia, independent of each other, as well as in conjunction with each other upon farm succession statuses and decisions. The methodology
  • is described in detail, especially the discrete choice models by which these influences were assessed. The results were linked with findings from other researchers and show that the householder’s perceptions about mountain farms, work and life on the farm
  • , as well as tradition hold the most vital role with regard to succession on mountain farms. At the same time, in order to ensure succession and continuation of farming on the mountain farm, an appropriate economic basis must be assured. - (IKR)

  • The Horcones Valley is situated in south part of the Andes and belongs to the most tourist developed mountain valleys in the region, thanks to the main tourist route to the Aconcagua summit. During the expedition which took place between January
  • and February 2008, the research and observations of trekking, alpinism and tourist development in the Horcones Valley were undertaken and the results were presented in this paper. - (BJ)

  • This paper discusses the applicability of constructed wetlands at Triglav national park mountain huts as the way of tackling hydro-ecological problems. This process has many advantages in comparison to the use of classic wastewater treatment plants
  • . Due to some limiting factors there were 18 out of 36 mountain huts suitable to be included in the research. In this paper the priorities in the process of solving hydro-ecological problems with the use of constructed wetlands are stated, based
  • on the evaluation of the degree of vulnerability. The analysis shows that present draining and purifying wastewater is not in compliance with the law at none of the mountain huts. This problem can only be solved efficiently by building the constructed wetlands at 12
  • mountain huts, at 6 of these this process is highly recommended. - (IKR)
