that a greater longevity of contemporary thin snow cover at 4800 m a.s.l. permits progressive sub-surface cooling with depth. However, the near-surface ground temperature profiles suggest that conditions are not conducive to permafrost development at these sites.
An analysis of ten-minute albedo variations, recorded on Haut Glacier d'Arolla, over an 11 day period in the 1999 ablation season is presented. Most of the short-term (
to calculate albedo variation as a function of cloud cover is developed.

permafrost. The good agreement with temperature-based methods validates empirical approaches such as the relation between bottom temperature of snow cover (BTS) and permafrost occurences, and further supports the findings from the geophysical surveys.
Geographic information system and spatial effect. Applied to the study of the relationship between dynamics of ligneous cover and sheep breeders' practices
For establishing the realistic earthquake threat in Hungary the sequence of prehistoric earthquakes need to be known. For this the interval covered by records is too short period, significant earth movements should be known for the last 10-20
Author investigates the environmental and geomorphologic conditions of red mud deposits whish were laid down behind the flood protection dams of the Danube on the low and high plains of the river, covering an area of 200 ha. The potential

Eleven stations located at different altitudes in the Italian part of the Lake Maggiore watershed (North-Western Italy) were selected to highlight trends in temperature and precipitation. The data available cover a period of about 30 years for six
the grassland zones in the tropical humid Andes. In the last 30 years there has been an important change in land use patterns replacing the natural grassland cover by settlements and cropland. - (IFL)
instrument, a consensus-based strategy that serves the realization of spatial planning objectives. It covers the entire implementation cycle, starting with the gathering of information, planning and decision-making up to the management and monitoring of its
The Abruzzi Pliocene basin covers the outer part of the present central Apennines chain-foredeep-foreland system and records the last deformation phases associated with the migration of the Apenninic orogen. This basin is divided into four main
