The integration of GIS and fuzzy multi-objective linear programming - an interactive decision making tool in sustainable use of agricultural land.

Canh Dinh Le

GIS and Fuzzy Multi-Objective Linear Programming (Fuzzy MOLP) are combined to solve the multi-optimization problem economic efficiency, employment, and environment in agricultural land-use planning. This method is applied to Bao Lam District, Lam Dong province, Viet Nam. First, GIS is used to create a land suitability map for the study area. Next, based on this suitability map to formulate the MOLP with 4 objectives as follows: maximize gross output (Z1), minimize cultivation cost (Z2), maximize employment (Z3) and maximize land cover in order to reduce soil erosion (Z4). The application and its results demonstrate how the method enables decision makers to identify the most suitable land-use alternatives by changing relative weight of each objective before deciding the most appropriate option for Bao Lam District.
