French Polynesia is a French overseas territory extremely vulnerable to climate risks. However, local risk management strategies focus on crisis management to the detriment of long-term resilience strategies, without integrating the pre-crisis, crisis and post-crisis periods. Through a decision support process, a serious game, intended for local residents, has been developed within a risk and resilience observatory. The objectives of this serious game are multiple: to increase knowledge of risks and resilience in local communities; to develop an understanding of the systemic complexity of resilient risk management; to develop an entertaining and educational tool. This prototype has been developed and tested in French Polynesia. This prototype allowed the players to create links between their sensitive experiences and their theoretical knowledge, allowing them to associate these two dimensions for a better understanding, acceptance and adoption of complex notions, concepts and processes.
