Three main dimensions of water management that Monobe River is now concerned are “chisui,” flood control, “risui,” water utilization, and “kankyo,” environment. The Ministry of Land, Infrastructure and Transport (MLIT) prepares the River Improvement and Maintenance Plan (RIMP) for Monobe river to realize in these three dimensions. Another milestone to develop and manage Monobe River was originally proposed by Association of forest and water in Monobe River for the 21st century (the 21st century) whose vision is to strengthen water resources through aiming at global optimum in the region by co-operating each other. As currently envisioned, conflict between MLIT and the 21st century emerged form MLIT planning process and project implementation. To address this problem and identify root causes of conflict issues, this study aimed at analyzing the different understanding between the MLIT members and the 21st century members by employing mental model approach. In order to elicit the multi-stakeholder mental model, interviews and dialogue conversation, related to implemented projects, were conducted regarding project management process. The study results showed that MLIT takes flood control as a priority consideration and pays attention to improvement of environment while the 21st century understands importance of flood control but perceive that MLIT’s efforts for environment improvement is not sufficient in some concrete projects. Insufficient consideration of environment by MLIT is observed in some areas due to their lack of experiences or their internal constraints. In order to contribute to more equitable, efficient and sustainable water use and management of the Monobe River, therefore, it is suggested that MLIT should incorporate with the 21st Century to utilize both experiences and wisdoms.}, publisher = {Society for Social Management Systems}, title = {MULTI-STAKEHOLDER MENTAL MODEL IN MONOBE RIVER IMPROVEMENT AND MAINTENANCE}, volume = {8}, year = {2012} }
