    This study aimed at quantifying changes in urban area of the city of Kahramanmaraş (K.Maraş) between 1948 and 2006, and analysing suitability of existing land use (LU) to the land potential. Urban change information was derived from two black-white monoscopic aerial photographs, and IKONOS and the QuickBird images acquired in 1948, 1985, 2000 and 2006, respectively. QuickBird image and soil map with 1:25,000 scale were used to analyze suitability of the current LU pattern to the land potential.

    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 total arable land of Turkey is about 28,054,000 ha. The main income of the country is agriculture and agriculture based industry. However, the prime soils cover only 17.5% of the total land surface and the productivity of the rest of the soils is limited by topographical, chemical (e.g. high calcium carbonate content, alkalinity and low organic matter), and physical (e.g. water logging, texture) attributes. The diverse topography along with deforestation and unsuitable tillage and irrigation management has been inducing the rate of erosion in the country for centuries.

    Two different soil maps prepared by different institutes at scales of 1:200 000 and 1:25 000 covering identical areas were compared to determine the accuracy of reconnaissance. These soil maps are widely used in land resources assessment studies in Turkey. They were digitized and then the map layers were compared by using GIS technology in order to assess soil properties and land characteristics. The reconnaissance soil map at the scale of 1:200 000 has the highest accuracy for the slope.

    That was to perform a determination of land suitability classes for agricultural land uses in Ankara Imrahor valley and vicinity with this study. First of all detailed survey and mapping of research area was performed with aid of satellite data and topographic maps then four different soil serials and their fourteen different mapping units were described. For this units, 38 different land uses were describe as their soil and meterological properties and calculated their suitability for this region and determined and mapping their land suitability classes for agricultural purposes.

    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 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.

    The effective use of natural resources is one of the important issues of today. GIS is recently used as an effective tool for solution of complicated problems. Land use researches in landscape planning studies can be done reliably and practically by the use of GIS. Depending on the increase of demands on coastal zones, the determination of land uses and conservation of them gets more important today. Within this context, in this study, the past and the present land uses of Tekirdağ coastal zone is pointed out.

    This note has been prepared for the plenary session of the European Forest Week on “Forests and Water” taking place on Thursday, 23 October 2008 1 . Its objective is to stimulate a lively and well informed discussion by providing the reader with background information and proposing questions which participants in the session may wish to address during the discussion. The note presents linkages between the forest and water sectors, discusses collaboration between the communities and presents international legal and policy frameworks.
