    The aims of this study are to determine the appropriate peach orchard locations among Tokat Kazova lands and to classify the lands according to the suitability for peach cultivation by means of Geographic Information System (GIS). The distances and elevation differences of possible orchard locations to/from the available water resources, soil profile depth, soil profile texture, frost risk, land aspect, and land slope were considered as criterions to classify the lands of Tokat Kazova to determine appropriate lands for peach cultivation under Tokat Kazova conditions.

    Egypt, Western Asia, Northern Africa

    The paper focuses its analysis on the last three decades of the twentieth century. The basic assumption is that Egypt's economic performance during this period was less than satisfactory compared with the most successful examples in the far East and elsewhere. The paper also assumes that Egypt's initial conditions at midcentury compared favorably with the winners in the development race at the end of the century.

    The relief of an area has significant ecological impacts on the climate, vegetation and soil properties of the same area. Relief can show variances depending on steepness, altitudes or roughness of the land surfaces in a landscape are sloppy, low or high; or; rough or smooth. In the scope of this approach, elevation, slope gradients and aspects as landscape relief characteristics in the borders of Ardahan city were evaluated for tourism and recreation use. In order o determine the relief characteristics of the landscape, Geographical Information Systems (GIS) were utilized.

    The land use changes of İzmir Çeşme Coasts are determined by using remote sensing techniques in the period of 38 years. Temporal and spatial changes of land use are analyzed based on 3 land use maps which show 8 land use categories using the topographical maps and aerial photos in 1957-1976-1995. The dominancy of land use categories are calculated depending on grid map (1km x 1km). Each period of grid maps and land use maps are analyzed by spatial intersection method in GIS.

    In this study, detailed soil information based on Soil Mapping Units (SMU) that were identified during the soil survey were digitized using ArcGIS and Arc-View GIS software in order to create the Soil Information System (SIS) for the Turkish Republic of Northern Cyprus. A total of 7881 mapping units belonging to 109 soil series were compiled into the database. For each SMU geo-referenced physical, chemical and biological attributes in total 20 characteristics were entered. The selection of the criteria is based on the Soil Geographical Database for Eurasia and The Mediterranean.

    Recently, researchers indicated great changes in the chemistry of atmosphere due to faster oxidation of soil organic carbon. The increases of greenhouse gasses especially CO2 concentration can affect climate, plant physiology, microbial activity, soil organic matter, and decomposition. Soil can be a store or source for atmospheric CO2. The amount of soil organic carbon stored in the soil or release to the atmosphere depends on net ecosystem productivity and heterotrophic respiration.

    The objective of this study was to determine the most suitable method (or methods) to improve in the rangelands around Samsun-Turkey rangelands between 1993 and 1999. The 12 management treatments in this study included control, aeration, burning, herbicide application, fertilization, over-sowing, ploughing + resowing and a combination of all the treatments. A mixture of seeds consisting of alfalfa, sainfoin, smooth bromegrass, orchardgrass and blue wheatgrass was used for oversowing and in the ploughing + resowing plots.
