Abstract
Experimental analyses of real social phenomena have been difficult because of physical and ethical limitations. In this research, we developed a model that predicts process of change in agricultural structure by Community-based Agricultural Land Lease model (CALL model) applying Multi-Agent Systems (MAS). The CALL model is a simulation model based on artificial society in computer. The CALL model is expected to be a new approach to overcome these difficulties. Though the model should be further improved, it would be able to provide crucial information for local agricultural planning.
