GIS Based Multi-Criteria Analysis for Site Selection Analysis of Aquaculture Case Study of Around Kwan Phayao, Phayao Province

Abstract

Site selection is a key factor in any aquaculture success and sustainability. Its process was developed by applying the spatial multiple criteria evaluation (SMCE) along with aquaculture physical variables. The aquaculture variables consisted of: 1) land use and land cover, 2) water body and stream lines, 3) permanent streams, 4) altitude, 5) slope 6) soil unit 7) distance from road and 8) distance from the community. In the part of analysis, weighting and scoring were addressed. Variables were grouped by a logical model and the outputs showing the suitable areas which divided into 3 classes (low, moderate and high). After that, overlay with actual aquaculture site was managed in order to support in future planning and decision making processes for sustainable development.
