  • Given the importance of land cover to the field of remote sensing and, in particular, the many physical geographical applications of remote sensing, this progress report will focus on recent developments in land cover research. Initially, reviews
  • of recent developments in land cover classification and land cover change lead into discussions on environmental management and environmental understanding. Finally, a brief summary of general developments in the field of remote sensing is provided.

  • This paper summarizes the results of a complex physical geographical survey in the Püspökszilágy area. This is a nuclear waste disposal site where low and medium activity nuclear waste is disposed, deriving from the Paks Nuclear Power Plant. As part
  • of the study soil profiles were taken and analysed, geomorphological, slope category maps were prepared, and the extent of soil erosion was calculated. As a result future surface modifications and soil cover removal were expressed in tons/hectar and mm/year

  • A. analyses the land cover changes in three different time period on an approximately 100 square kilometres study area situated near the Hungarian border. First land cover registered by the first military survey is analysed, then later military maps
  • , and the 1998 CORINE land cover data base is compared and analysed. - (JS)

  • Soil erosion and mass movement processes on the loess covered areas of Hungary
  • This paper analyses the soil erosion and mass movement processes of loess sediments which cover roughly two-thirds of the total area of Hungary. Soil erosion is the greatest hazard on hill slopes under cultivation whereas mass movement processes

  • The paper reviews contemporary changes to the forest cover on mountains around world. These changes reflect the complex, dynamic relationships between society, the economy and land resources, and are also linked to a range of driving factors
  • reflecting land use and land cover change and biophysical constraints. This paper discusses three processes to land-cover conversion in mountain area ; i.e. deforestation, afforestation and natural forest expansion, within the framework of a forest transition
  • model which attempts to explain the phase-change from deforestation and a decrease in forest cover to forest expansion and an increase in the area of forest. - (BJ)

  • Active layer temperatures are presented from a rock glacier in the Swiss Alps. The data represent a full year (2002) covering parts of 2 very different winters. Winter/spring 2002 was very cold and dry; fall 2002 was characterized by an unusual
  • amount of snow. Active layer temperatures are examined together with climate data and are used to discuss the processes which control the thermal regime of an active layer on a slope of a bouldery rock glacier surface : snow cover, snow depth, non-linear
