ABSTRACT: In this paper connection between temperature changes and North Atlantic oscillation (NAO) has been investigated in the period from 1979 until 2006. Satellite temperature data from UAHMSU were investigated in relation to North Atlantic Oscillation index on the Earth, in Europe and in Serbia. Statistically insignificant correlation coefficient has been obtained for the area of Serbia. The analysis of periodicity of 2.8±0.5 year is in accordance with that one obtained by Landschieidt (2001). However, in order to give final conclusion regarding to climate change more parameters should be analyzed. .

ABSTRACT: The influence of anthropogenic factor on the landslide genesis is analyzed in this paper. Buildings, traffic, water supply and electro infrastructure are introduced in natural landscape as the result of human, living and economic activities in space. The conditions and processes which these objects can cause on the relation object-relief, and therefore initiate the occurrence of landslides, are the change of morphometric characteristics and the modifications of the water balance of slope. The zone with both qualitative and quantitative transformations of relief represents interactive zone in which the influence of man as a genetic factor or modifier of this colluvial process can be observed. .

ABSTRACT: In this paper the air temperature changes have been investigated on the base of satellite measurement, in the period from 1979 until 2006. The analysis has shown that there is no temperature amplification with altitude. Data for Serbia have shown negative trend of temperature in the last 20 years of the investigated period. Although it is not statistically significant, the sign is not in accordance with the increasing CO2 concentration. This may mean that the sign of satellite temperature doesn't support hypothesis about domination of anthropogenic greenhouse effects. .

ABSTRACT: The drainage basin is spatially and functionally clearly defined and relevant hydrologic, geomorphologic and ecologic landscape totality. Therefore, it mostly represents basic geo-spatial unit of generation, monitoring, and studying numerous physical-geographical and geo-ecologic occurrences and processes. One of the most important components of geo-space, on the level of basin, is manifested through the state and quality of surface waters. So, the acceptance of systematic approach in studying mineralization of the surface waters would contribute to the deeper understanding of the process in complex systematic surroundings which drainage basin represents. The Visočica Drainage Basin was chosen as proving ground of this kind of the research approach for several reasons. The highest specific runoff on the territory of Eastern Serbia, heterogeneous geologic structure of terrain, almost complete absence of the influence of the anthropogenic factor on the state of the environment, as well as the existence of water accumulation enabled perception of the values of dissolved mineral substances of surface waters as landscape-ecologic component of geo-space.

ABSTRACT: In this paper land erosion has been investigated from its temporal and spatial variability point of view. The aim of the application of contemporary soft wares and satellite observations was to create an adequate data base which allows faster and more adequate possibility for monitoring the intensity of erosive processes, as well as meaningful decision for application of different ways of anti erosive techniques of the most dangerous areas. Geomorphologic mapping of erosive processes using plane and satellite images has allowed rational planning of field observations and, at the other side very detailed establishing of the intensity of previous erosion. A new approach applied in this paper during data processing of all relevant parameters influencing erosion is based on using of software Geomedia 5.2 (Intergraph).
