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.

The main reason for government intervention in land markets is market failure. Open space is a non-market output or externality of farmland and, although it might be important to people, there is no actual market for the good as such. The Netherlands and the Province of British Columbia in Canada both experience similar problems of expanding cities and pressure on open space, and they both use zoning to regulate land use and its externalities.

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 CLC2006 databases were produced by the Centre for Geo-Information (Alterra-WUR), the NRC Land cover for the Netherlands. The national CLC2006 project took place under the umbrella of the overall GMES Fast Track Service Percursor (FTSP) Land Monitoring. The basis for the production of the CLC2006 databases was the CLC2000 database that was also produced by the same team of Alterra. Alterra was also involved in the production of the CLC1990 database and the change database between 1990 and 2000.

The spatial fragmentation of different biomass sources in one or more regions makes design and assessment of sustainable biomass delivery chains rather complicated. This paper presents a GIS tool that supports the design and facilitates a sustainability assessment of biomass delivery chains at a regional level, in terms of the regional availability of resources, costs, logistics and spatial and environmental implications. Green House Gas (GHG) efficiency targets are part of it.

In 2007, ICARDA celebrated its thirtieth anniversary. The Center and its partners have worked together for three decades to improve the food security and livelihoods of the poor in dry and marginal areas. During this time, we have seen significant changes in the biophysical environment and in socio-economic circumstances. New farming technologies, new livelihood options, and better policies and institutions are speeding up agricultural development in the world's dry areas, and we are proud of the role we have played in this progress.

Soil organic carbon (SOC) was measured in topsoil samples of agricultural soils from 311 locations of Jiutai County, Northeast China. The spatial characteristics of SOC were studied using the Geographic Information Systems and geostatistics. Effects of other soil physical and chemical properties, elevation, slope, soil type and land use type were explored. SOC concentrations followed a lognormal distribution, with a geometric mean of 1.50%. The experimental variogram of SOC was fitted with an exponential model.

We introduce a simple method for estimating the changes of nitrate concentrations in surface waters regarding the land use modification. Stream and drainage water nitrate concentrations in prevailingly agricultural catchments of three different scales located in the Crystalline complex of the Czech massif, Czech Republic, were included in this study. Water quality samples were collected through the years 1992-2006 at monthly and bi-monthly intervals.

The main aim of this study was to determine the dependence of yield and selected soil properties on topography of the experimental field by using topographical data (elevation, slope and flow accumulation). The topography and yield data were obtained from a yield monitor for combine harvester, soil properties data were taken from sampling points of our experimental field. Initially, the topographical parameters of elevation and slope were estimated and then the Digital Elevation Model (DEM) grid was created.

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.
