Sustainability is a topic with deep implications, as reflected by the approval of the 2030 Agenda for the sustainable development that has 17 Sustainable Development Goals (SDGs). One of these SDGs tries to achieve the sustainability of cities, for which we have verified that their resilience is necessary against natural hazards (NH). For the persistence of NH through time on a world scale, it is crucial to train expert technicians in the prevention and control of these risks. For this research, two studies have been made, one focused on research into the training of environmentalists by means of gamification, and the other to verify the potential of this same tool in the NH analysis and management. With this work we have been able to verify that the model of city designed can be an alternative and more sustainable model to the current solutions, also corroborating the usefulness of simulation in their design and its role in the resilience against NH. On the other hand, in relation to the teaching of the subject under study, based on the competences studied, this study is considered successful, demonstrating the utility of gamification and simulations in the formation of environmentalists.
