DETERMINATION OF SUITABLE AREAS OF APPLE (MALUS DOMESTICA) CULTIVATION WITH AHP AND GIS TECHNIQUES

The planning of crops to be grown in agricultural land has an important place in terms of sustainable development. In this study, it was aimed to determine the suitable areas for apple cultivation in all the land of Korkuteli district in Antalya province. For this purpose, Analytical Hierarchy Process (AHP) method, which is frequently used in suitability analysis, was used. Analytical Hierarchy Process is a multi-criteria decision-making method that makes complex problems simpler and provides solutions. This study consists of three basic stages. In the first stage, parameters related to the study area and the AHP methods were determined and data for the area was obtained. In the second stage of the study, analysis with geographical information systems (GIS) and AHP were carried out. The weights of the AHP parameters were determined according to each other by taking their importance into consideration and their suitability was checked with the consistency rate (CR = 0,057). In addition, a weighted overlay analysis was performed according to weight values and importance rates determined at this stage. At the last stage, suitable areas for apple cultivation were determined and a suitability map was established. At this stage, the study area was separated into five categories according to the United Nations Food and Agriculture Organization (FAO) land suitability classification. According to the obtained suitability map, it was determined that 14,86% (34791 ha) of the study area was highly suitable, 13,79% (32270 ha) was moderately suitable and 8,47% (19817 ha) was marginally suitable for apple cultivation. It was determined that unsuitable area ratio for apple cultivation was 45.29% (106015 ha) and completely unsuitable area ratio was 17.59% (41166 ha). In the study, the results of the analysis were compared with the agricultural areas in the land use of CORINE 2012. According to this, it was seen that the total area determined suitable for apple cultivation overlaps with the total agricultural areas in the land use of CORINE 2012
