  • Evapotranspiration represents two processes, evaporation and transpiration. As both processes occur simultaneously it is not easy to distinguish them. Evapotranspiration is influenced by three groups of factors (meteorological factors, plant factors

  • This study, carried out in Piura Province in northern Peru, combines broad and fine scales to investigate temporal changes : at broad scale the AA. use aerial photos (from 1949, 1962, and 1999) and GIS to document land-cover change during a long

  • The AA. compared karren formation of various slopes (3 bare slopes and 2 with a plant patch) in a glacier valley close to Tragl peak (in Totes Gebirge, Austria). It could be established that bare slopes have a larger average specific width, channel
  • shape and channel density. The dynamics of karren features are different on the bare slopes and slopes fed from a plant patch. Karren features tend to widen on bare slopes, while they tend to deepen on slopes with a plant patch. The specific width

  • This work investigated the effects of land cover and land-use change (LUC) on the ability of a soil to store carbon (C) and reduce carbon dioxide (CO2) emissions, in a Mediterranean area. Using a paired-site approach, the AA. estimated the effect
  • of land-cover change on the C stock from 1972 to 2008 in a natural reserve (Grotta di Santa Ninfa) in western Sicily. They selected 15 paired sites representative of 5 LUCs. The results indicate that land-use conversion, vegetation type, and management

  • The study sites were in the Cobar Pediplain region of semi-arid New South Wales, Australia. In order to quantify ground cover and soil related thresholds for runoff and sediment production, the AA. used a data mining technique known as conditional
  • the critical role of soil surface roughness, particularly where total ground cover is sparse. The analysis also provided evidence that a two-phase mosaic of patches and inter-patches identified via rapid visual assessment could be further delineated
