    EVALUATION OF LAND TENURE FORMS AND SIZE OF AGRICULTURAL HOLDINGS IN TURKEY USING GEOGRAPHIC INFORMATION SYSTEM (GIS) TECHNOLOGIES
    (HEALTH & ENVIRONMENT ASSOC, 2016) Iscan, Fatih; Yagci, Ceren
    Agriculture sector plays strategic roles in the process of economic development because agriculture is the basic source for food supply of all countries in the world. While population increase day by day, global resources like oil, fresh water, topsoil and also agricultural products decline so land management is very important for heritage of sustainable planet. The legal expression of farmlands among with operator is land tenure which is a significant component in agricultural land use. Determination of land tenure and the farm size is important for a better understanding of the structure of the agricultural land. Geographical Information Systems emerge that can expressed such as situation. Geographic and non-geographic attributes of spatial datasets enable them to be integrated and analyzed in GIS applications through visualization and analysis tools. The purpose of this paper is evaluate to land tenure and the farm size in provinces of Turkey using GIS. The land operated by size, number, rented land, share basis, their own land of agricultural holdings and land tenure forms analyzed. It is detected the differences among provinces from analyzed results taking everything into account. The results obtained from the study are discussed and suggestions are made.

    Fuzzy expert system for land reallocation in land consolidation
    (PERGAMON-ELSEVIER SCIENCE LTD, 2011) Cay, Tayfun; Iscan, Fatih
    One of the most important steps of land consolidation projects is land reallocation studies. In Turkey, reallocation studies carried out in the scope of land consolidation projects are made according to farmer preferences (interviews). In addition to interview-based land reallocation model, mathematical models have been used in the previous optimization studies for reallocation procedure. Recently, fuzzy logic method, which is capable of modeling human mindset and used when other forms of mathematical models cannot be developed, has also been applied to the field of geomatic engineering, as well as in other engineering branches. This study examined the applicability of a fuzzy logic method at the reallocation stage of land consolidation study, where development of an accurate mathematical model was not possible. The results obtained from the fuzzy logic-based land reallocation model were compared with those obtained from the interview-based land reallocation model. Farmers were surveyed to determine which land reallocation model they preferred. The results indicate that 80.5% of the participant landholdings were satisfied with the fuzzy logic-based reallocation land model, while 50% were with the interview-based land reallocation model.

    GEOGRAPHIC INFORMATION SYSTEMS (GIS) BASED APPROACH FOR SITE SELECTION OF MEDICAL WASTE LANDFILL IN KONYA
    (HEALTH & ENVIRONMENT ASSOC, 2016) Yagci, Ceren; Iscan, Fatih
    Medical waste generally consists of many different types of materials so it cause environmental hazards and public health risks. Therefore to protect public and environment local authorities must take special measures associated with medical waste management. Medical waste site selection has been taken into account for better management in urban areas. In this study, candidate sites for an appropriate landfill area in Konya are determined by using the integration of Geographic Information Systems. For this purpose, six input map layers including, settlements (urban centers and villages), roads (Highway and village roads), railways, slope, irrigation canal, grasslands are prepared and simple additive weighting method is implemented to a geographical information system. A final map was generated which identifies regions showing suitability for the location of the landfill site. At the end of the analyses, candidate sites are determined. Among these candidates, the most suitable potential landfill site should be selected by decision makers in Konya.
