Integration of AHP and GIS for Landuse Suitability Analysis

A Case Study of Spatial Decision Support for Groundwater Conservation in Kumamoto City

Abstract

The aim of this paper is to provide recommendations for future landuse alternatives in the conservation of groundwater using the optimum landuse. In Japan, decisions relating to regulations against landuse often involve difficult problems such as individual property rights.. However, it is essential for citizens to make decisions concerning future landuse because problems are related to the realization of effective public welfare. The area of interest in this study is Kumamoto City. The method applied in this study is the AHP application for suitability analysis. This method is employed in order to identify suitable landuse for groundwater conservation. This study provides three alternatives. The visualization of alternatives using GIS is useful to support citizens in decision making processes regarding groundwater conservation and alternative landuse.
