  • The subject of the studies are these agricultural problem areas in Poland. The first part reviews the concepts and main thrusts of research, against the background of the subject literature, as well as the empirical results obtained. The second part
  • entails a delimitation and characterisation of agricultural problem areas. A variety of methods were used to identify and describe areas backward in their development, areas of productive reserves, areas of unfavourable environmental conditions
  • and conflict areas. In the third part, attention is paid to the evolutionary character of agricultural problem areas. - (L'A.).

  • Palaeogeographic evolution and seismotectonic implications of the broader area of Eurotas River (Greece) during the Quaternary
  • In this paper, an attempt is made to study morphologically the various landforms that make up the landscape of the Eurotas area, to correlate the geomorphic and seismotectonic elements in order to comprehend the palaeogeographic evolution
  • of the area during the Quaternary, and finally to draw some conclusions regarding the seismic hazards of this area.

  • The aim of this paper is to quantify the load of organic carbon, nitrogen and phosphorus from 2 large catchment areas, the River Kitka and the River Oulanka, and the transport of the nutrients into Lake Paanajärvi, a deep oligotrophic lake in NW
  • Russian Karelia. In both areas the annual leaching and transport of nutrients were highly dependent on the hydrological conditions.

  • The aim of the research reported in this paper was to estimate the soil and nutrient loss in the catchment area of the Örvényes-Séd stream. Using GIS (EPIC-EROTOP) method first erotopes were deliniated for the investigation area then these erotopes
  • were further divided according to land use and soil types. Soil loss estimation was carried out with runoff conditions in the catchment area. The soil protection value of the different crops was also calculated. - (ZK)
