Özet:

 This study assessed the suitability of agricultural land within the Zamantı Watershed, located in the Seyhan Basin of Turkey, using Multicriteria Decision Analysis MCDA within a Geographic Information Systems GIS framework and the Analytical Hierarchy Process AHP method. Eight criteria, including elevation, soil, land use, slope, precipitation, drainage density, aspect, and water source proximity, were used to evaluate different regions within the basin. Data from various sources, such as the Digital Elevation Model DEM, the CORINE Land Cover CLC database, rainfall data from Turkey General Directorate of Meteorology and soil data from the Food and Agricultural Organization FOA, were utilized. The AHP methodology determined the relative importance of the criteria and sub-parameters through pairwise comparison and the Consistency Ratio CR analyzed the consistency of the pairwise comparison matrix. The results indicated that 78 of the study area was suitable for agricultural production, with 14.72 being highly suitable, 34.38 moderately suitable, 29.44 typically suitable, 17.93 not suitable and 3.53 permanently unsuitable. The highly suitable areas had flat topography and suitable soil. The average elevation of the basin ranged between 1,000 m and 2,000 m, resulting in slopes that were suitable for agricultural activities. The shape of the basin boundary allowed for easy irrigation of the farm areas as the most remote areas of the basin were located less than 25 km away. The study provided a comprehensive assessment of the suitability of the Zamantı Watershed for agricultural production and could be used for agricultural development of the region.
