Öğe Comparison of designed different land reallocation models in land consolidation: A case study in Konya/Turkey(ELSEVIER SCI LTD, 2015) Uyan, Mevlut; Cay, Tayfun; Inceyol, Yasar; Hakli, HuseyinLand consolidation (LC) is the most favorable land management approach for solving agricultural land degradation. LC is essential for ensuring the economic viability of rural areas, facilitating environmental management, or rationalizing urban growth. LC projects consist of various steps. Land reallocation is the most important stage of LC studies and a tool which rearranges proprietary rights. For fast and efficient progress in projects, usage of computer technology has been essential. In this case study, designed two different land reallocation models (SDSS-based and GA-based land reallocation models) is compared for LC projects in reallocation of newly created regular size parcels to landowners. As a result of these comparisons, the GA-based model is some successful than the SDSS-based model in terms of average parcel size, number of parcels and average number of parcels per land-owner. The benefits derived from both models are much higher than conventional models. (C) 2014 Elsevier B.V.

In Turkey, these lands are obtained by state institutions and organizations by expropriation. A lot of problems and troubles occur when the lands, which are needed by state institutions and organizations, are obtained by expropriation. These problems and troubles gain different dimensions as applications increase. There are varieties such as financial dimension, sociological and psychological, dimension of managing the money come from finance. It is necessary to use existing law and legislations in the country for minimizing hitches emerge while obtaining the lands which are needed for minimizing these problems. In this study, expropriate method, which is one of the land obtaining methods; expropriation amount paid to peasants of Yozgat-Delice Tatlicak, Yeniyapan villages', which are on the route of Ankara Sivas High Speed Train are studied. Economic results and costs of obtaining same length of high speed train route by land consolidation method are compared.Öğe EVALUATION OF LAND REFORM POLICIES IN TURKEY(SELCUK UNIV PRESS, 2017) Cay, Tayfun; Toklu, Nuh; Esen, OmurTurkeys agricultural policies of the European Union, World Bank, International Monetary Fund on a global scale, such as areas of activity by the organizations and groups, referral is made. Since the beganning of the Republic of Turkey, land reform has been different application. "On June the 11 th 1945, a Law to Provide Farmers with Land enumerated 4753, Land and Agrarian Reform Law dated 1973 and Enumerated 1757, Agrarian Reform Law Regarding Land Regulations in Irrigation Areas, Land Protection & Land Use Law enumerated as 5403/5578" applications have handled in within Turkey land reform. In region of the land reform applied, had been a lot of problem for example, lack of credit, absence of qualified personnel for giving information, etc. and had not gotten efficiency to expected performance and successed expectancy.& para;& para;In this study, land reform, according to the particular application in the world have studied the similarities and differences. A viable model for our country's land reform was formed.Öğe Evaluation of reallocation criteria in land consolidation studies using the Analytic Hierarchy Process (AHP)(ELSEVIER SCI LTD, 2013) Cay, Tayfun; Uyan, MevlutLand consolidation (LC) can be described as the rearrangement of land areas according to developing agricultural technology. Land reallocation is the most important phase of LC. The reallocation process is a legal obligation in Turkey which takes into account landowners' preferences. First, the planner determines these preferences at interview. These interviews should be performed very carefully, because they are a tool for rearranging property rights. In this study, preferences for reallocation process were determined with the Analytic Hierarchy Process (AHP). The results of an AHP-based land reallocation model were compared with the results of an interview-based land reallocation model, which is the classical model. According to the results, 62.7% of the participants were pleased with the interview-based land reallocation model, and 91.5% with the AHP-based land reallocation model. (C) 2012 Elsevier Ltd.

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.

This process, measured in weeks or months, is usually performed manually by a technician with the support of computer software. Although various techniques have been developed in recent years to solve this complex problem, they all require improvement. This study aimed to develop a new technique and produce applicable redistribution plans using a genetic algorithm (GA) in combination with an expert system. Blocks of cadastral parcels were determined by a GA using a new objective function to consider the overflow and residual areas as well as the landowners' preferences. The expert system was employed to close (reduce to zero) the overflow or residual areas occurring after the GA distribution. To investigate the performance of the proposed method, the system was used on a real study area and the results were compared against those obtained for the same cadastral situation undertaken by a technician using a similar method from published literature. The experimental results showed that the method proposed in this study performed better than the other methods because it provided a successful and applicable redistribution plan for the study area in a much shorter time.Öğe Intersection road accident analysis using Geographical Information Systems: Antalya (Turkey) example(IEEE, 2013) Ertunc, Ela; Mutluoglu, Omer; Cay, TayfunSince the basis of traffic safety study is based on the exact information, exact information is reached in order to minimize traffic accidents. Geographic Information Systems (GIS) are performed related to an accident data collection, storing, statistical analyzing, visualizing and testing of results as soon as possible and a detailed manner. In this study, a database has been created with Arcmap-10 software using fatal-injury traffic accident datas at intersections in Antalya City Center between 2009 and 2010 years. Statistical evaluations of accidents were conducted in both visual and graphics using these traffic accident datas on a satellite map with ArcMap-10 software. Hot spots for intersection accident were determined in GIS.Öğe KONYA CITY URBAN SPRAWL AND ENVIRONMENTAL POLLUTION RELATION(HEALTH & ENVIRONMENT ASSOC, 2016) Ayturan, Zeynep Cansu; Cay, Tayfun; Dursun, SukruKonya is the biggest city of Turkey with respect to surface area which covers 5% of total surface area of Turkey. Moreover, population of the city is increasing day by day with immigrations and births. This extreme growth of population causes some problems in city planning and urban development. Urban sprawl is one of the most significant consequences of wrong urban planning in order to provide demand of settlement. It is defined as insatiable and inefficient use of land with continuous monotonous development and discontinues rapid development. Urban sprawl has seen mostly at the centre districts of Konya (Meram, Karatay, Selcuklu) and around Seydisehir ring road. This sprawl problem of Konya city has many effects on humans and also environment. These effects include both social and economic aspects. For example, increasing air pollutants because of the urban sprawl and unplanned settlement may create health problems on people and spoil air quality of the city. Destruction of ecological life and natural environment, pollution in rivers and streams are some of the other environmental problems caused by urban sprawl. In this study, environmental pollution originating from urban sprawl problem in Konya city was investigated and possible recommendations to solve urban sprawl problem was explained.Öğe Modeling of reallocation in land consolidation with a hybrid method(ELSEVIER SCI LTD, 2018) Ertunc, Ela; Cay, Tayfun; Hakli, HuseyinLand consolidation is one of the important tool of increasing productivity in agricultural production. Land consolidation not only consolidates fragmented land, but also improves the standards of landowners in agriculture, technical, social and cultural areas. Land consolidation projects consist of various stages. The most important, complicated and time-consuming part of these stages is land reallocation. Land reallocation is a process which requires a long time and high operating costs and in which there frequently arise disputes between landowners. For these reasons, it is inevitable to use computer technology to optimize this process. In this study, a hybrid method including genetic algorithm and fuzzy logic techniques which enable reallocation to be done automatically in land consolidation has been used. The crossover rate and the operation of the genetic algorithm (GA) method have been realized as a self-adaptive structure using fuzzy logic techniques A similar study used for the land reallocation problem in the literature, the results of reallocation plans obtained by the technician and the results obtained by the hybrid method have been compared. When the experimental results are evaluated, it has been found that the hybrid method used is more successful and efficient than similar studies in the literature and also has a better reallocation plan.Öğe A new approach for automating land partitioning using binary search and Delaunay triangulation(ELSEVIER SCI LTD, 2016) Hakli, Huseyin; Uguz, Harun; Cay, TayfunOne of the most important, yet time-consuming steps of the land consolidation process, which is related to pooling fragmented lands together, is the production of land partitioning plans. After the land redistribution process is finished, the land partitioning process begins. In that process, the locations of parcels within the blocks are determined. Due to the non-uniform geometric shapes of the blocks, the areas of the parcels cannot be divided directly. The production of an ideal land partitioning plan is not suitable automatically unless a quick, accurate process to divide the lands is secured. In this study, production of a pre-land partitioning plan is realized using both the binary search method and the Delaunay triangulation method, taking into consideration shape, size, value and road access criteria. The result of the experimental study shows that the proposed approach for dividing the parcels makes the process take place more quickly. Thus, a solid base for creating an automatic land partitioning plan-one that is closest to an ideal plan-will be provided with this study. (C) 2016 Elsevier B.V.

Geostatistical methods have been used widely as a convenient tool to make decision on the management of groundwater levels. To evaluate the spatial changes in the level of the groundwater, geographic information system is used for the application of universal kriging method with cross-validation leading to the estimation of groundwater levels. The resulting prediction mappings identify the locations of groundwater level fluctuations of the study area. The average range of variogram (spherical model) for the spatial analysis is about 9,200 m. Results of universal kriging for groundwater level differences drops were underestimated by 15 %. Cross-validation errors are within an acceptable level. The maps show that this area of high decrease of groundwater level is located at the southwest. Kriging model helps also to detect sensitively risk prone areas for groundwater withdrawing. Such areas must be protected with an effective management procedure for future groundwater exploitations.Öğe Spatial and Temporal Groundwater Level Variation Geostatistical Modeling in the City of Konya, Turkey(WILEY, 2009) Cay, Tayfun; Uyan, MevlutGroundwater is one of the most important resources used for drinking and utility and irrigation purposes in the city of Konya, Turkey, as in many areas. The purpose of this study is to evaluate spatial and temporal changes in the level of groundwater by using geostatistical methods based on data from 91 groundwater wells during the period 1999 to 2003. Geostatistical methods have been used widely as a convenient tool to make decisions on the management of groundwater levels. To evaluate the spatial and temporal changes in the level of the groundwater, a vector-based geographic information system software package, ArcGIS 9.1 ( Environmental Systems Research Institute, Redlands, California), was used for the application of an ordinary kriging method, with cross-validation leading to the estimation of groundwater levels. The average value of variogram (spherical model) for the spatial analysis was approximately 2150 m. Results of ordinary kriging for groundwater level drops were underestimated by 17%. Cross-validation errors were within an acceptable level. The kriging model also helps to detect risk-prone areas for groundwater abstraction. Water Environ. Res., 81, 2460 (2009).
