Abstract
This paper examines environmental disputes solutions for wind power siting using negotiation simulation in which participants play actors who are forming a game community, interact each other under negotiation rule and accordingly consensuses are simulated. Availability of the simulation is also examined. Main findings are summarized as follows. First, initial framing for negotiation and mediation in negotiation process are important for trust among actors and procedural justice. Second, effects of the simulation are observed as participants' significant attitudes change before-and-after simulation. Third, one of the solutions recognizes a necessity of “joint fact-finding” which ensures continuous dialogue.
