GIS-based Multicriteria Analysis for Agricultural Land Use Planning in the Western Region of Quang Tri Province,Viet Nam
The main purpose of this research was to develop an agricultural land use plan for the production of rice,maize,cassava,rubber,and coffee in the hilly and mountainous part of the Quang Tri province.To this aim,a GIS-based multicriteria procedure has been developed consisting of the (1) design of crop-specific criteria,(2) standardization of criteria,(3) assignment of criteria weights,and (4) additive or multiplicative combination procedures.The overall score values were classified into the corresponding suitability classes based on the land characteristics-yield relationship reported in the province.Next,a set of priority rules were developed in order to determine the optimal land use plan,taking into account agro-ecological,as well as environmental and socio-economical requirements.The procedure proved successful to determine a preliminary land use plan for the province,indicating options for the expansion of the agricultural land.It also identified some limitations of the dataset as well as options for the improvement of the methodology.
