A GIS-based multi-criteria decision analysis approach using AHP for rural settlement site selection and eco-village design in Erzincan, Turkey

Abstract

In recent years, natural resource depletion, rapid population growth, and increasing urbanization have all reached new heights. All of these ecological problems that exceed the planet's absorbing capacity, have begun to imperil both human life and nature itself. Rural settlement plans aim to optimize the use of natural resources. Agricultural lands are used for non-agricultural purposes as a result of proper placement planning of rural settlements. The suitability of land for a specific purpose is determined via suitability analysis. Therefore, it is extremely important to use technological innovations in the selection of rural settlement areas in addition to considering the technical, economic, and social factors in determining the most suitable locations. With the advancement of computer technology, Geographical Information System (GIS) has become an important tool for more effective use of rural areas. In this study, the most suitable rural settlement area was determined by using GIS in Erzincan Province. Technical, social, cultural, and economic criteria were developed for the selection of the location. Alternative locations were analyzed using the GIS, Multi-Criteria Decision Analysis and the Analytical Hierarchy Process method based on the criteria and site data. The most suitable areas for rural settlements were chosen as the Merkez, Tercan, Kemaliye, and Kemah districts in Erzincan Province. caglayan town in the Merkez district has been determined as the most suitable region for an eco-village and a cost calculation and 3D eco-village design were carried out in Caglayan.
