    Gis-Based Determination of Suitable Agricultural Areas and Comparison With Current Land Use, the Case Study of İzmir
    (Izmir Institute of Technology, 2022) Ekinci, Özge; Demirkesen, Ali Can
    Agricultural production is the main source of life for humanity. In order to the protection and proper use of agricultural lands are of great importance. İzmir has a high potential in terms of agricultural areas. There are three basin areas within the provincial borders and fertile agricultural areas where the continuity of agricultural production can be ensured. With the effect of urbanization and population growth, the settlements expanded towards agricultural areas. For the correct use, sustainability and efficiency of agricultural lands, the most suitable areas in terms of agricultural production should be analyzed correctly. This study was carried out to determine the most suitable areas for agriculture in İzmir. The study considers a Geographic Information System GIS-based approach. The combination of multi-criteria decision analysis (MCDA) and GIS can be used in the process of generating solutions for complex planning problems. In the first stage of the study, the criteria were weightlessly overlayed, and a result map was obtained. In the second stage, weights were obtained for each criterion using the Analytical Hierarchy Process (AHP). Suitability analyzes for the study area were obtained by weighted overlay analysis using GIS. Environmental characteristics, soil characteristics and economic factors were taken into account while performing the suitability analysis for agricultural areas. The same criteria were used for both suitability analyses. As a result of the comparison between the two maps, a resultant map obtained by the weighted overlay method was found to be more reliable, and the results were compared with the current situation. In the current situation comparison, Great Lowland Protection Areas, 1/100000 Scaled Environmental Plan, and Law No. 5403 are discussed. When the comparisons were made, the areas that differed with the current situation were determined. It is seen that the agricultural lands obtained as a result of the suitability analysis are spread over wider areas compared to the current situation.

    Gis-Based Determination of Suitable Areas With Multi-Criteria Approach for Solar Power Plants and Assessment of Land Decisions: the Case Study of İzmir
    (01. Izmir Institute of Technology, 2021) Toprakcı, Nevin Selin; Demirkesen, Ali Can
    The need to energy has become an important reality for human life with the increase in living standards and population. İzmir has important renewable energy sources especially solar energy. Rapid urbanization and environmental problems due to internal migration after the 1960s have made renewable energy sources a priority because of the wrong implementations of urban policies in İzmir. In order to talk about energy potential, it is first necessary to talk about and analyze the land potential. It is necessary to determine the true criteria and methods for true analyzes of the suitable areas for efficiency and sustainability. The study presents a GIS-based approach to identify the most suitable area for Solar Power Plants (SPP) development in İzmir. The first suitability map includes 9 criteria. The last suitability map includes the first suitable map results and criteria of land capability class (10th criteria) using the same method. It can be said that the SPP installation is more suitable, especially the northern part of İzmir and districts of border. When the evaluation is compared, it can be said that İzmir has fertile lands and it should definitely be taken into account in energy projects. It also draws attention importance of land use decisions and legislation while choosing the suitable area from perspectives of planning. In addition, the current and potential solar energy area choices were evaluated together with the results which are produced for the study area in terms of land decisions and planning.

    Gis-Based Multi-Criteria Approach for Land-Use Suitability Analysis of Wind Farms: the Case Study of Karaburun Peninsula, Izmir,-Turkey
    (Izmir Institute of Technology, 2015) Sediqi, Khwaja Jawid; Özdemir, Semahat; Saygın, Mustafa Ömür; Saygın, Mustafa Ömür; Özdemir, Semahat
    This study presents a GIS-based multi-criteria approach to identify the most preferred or suitable site for wind farms development in Karaburun Peninsula, İzmir. Criteria for analysis have been identified based on literature review and experts’ opinions. The selected criteria include environmental, technical, and economic as well as social factors. In order to estimate the weights or relative importance of the criteria, the pairwise comparison method in the context of Analytic Hierarchy Process (AHP) is implemented. The overall suitability of the study area is determined through the Weighted Overlay method, which is a sufficient weighted approach in geographical information system (GIS) environment. The outcome or suitability map is classified into five scored classes from the most suitable to less suitable and restricted area. On the whole, as the selection of optimal site for the wind farm development is a multi-dimensional process, this thesis intends to consider the following three significant subjects; (a) evaluating and identifying the most influential criteria for land suitability analysis of wind farms, (b) applying AHP as a multi criteria decision-making method to determine the criteria weights, (c) utilizing GIS as a tool to overlay the overall criteria and consequently to identify the potentially suitable location for the wind farms development. Regarding to the above mentioned, eight the most influential available criteria, which are consisted of wind potential, distance from preservation area, distance from settlements, forest, slope, elevation, distance from roads, and agriculture area are identified. Base on pairwise comparison different weights for each criterion is determined. Finally, by using GIS the suitability map for the study area is provided and the result compared with the existing wind farm locations.
