Abstract

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
