Abstract

Secondary data collected from relevant agencies in the study area and primary data from soil sampling and interviewing experts and professional staff were used in a multi-criteria assessment model using the Fuzzy analytical hierarchy process method. Based on overlapping 12 maps featuring the natural, economic and social factors, we identified 119 land units for orange cultivation. The results show that the natural factor is the most significant (with a weight of 0.674), followed by the economic factor (0.212) and the social factor (0.114). These findings indicate that improving soil quality is necessary to raise the land suitability for orange cultivation. Among land suitability for orange trees, 1,756.11 ha is considered to be suitable for S2 (12.25% of the total agricultural land); 2,714.62 ha is less suitable for S3 (19.80%), and 9,857.22 ha is unsuitable for N (68.85%). The Fuzzy-AHP is an effective method for multi-criteria land evaluation with the participation of various stakeholders.
