Executive summary:
The document provides guidelines on how to develop Scenathons or scenario marathons, as a methodology to achieve a positive and open interaction with decision-makers related to water management. Scenathons are a type of serious game used to foster the integration and understanding of complex scientific models in the decision-making processes. They are part of a broader stakeholder engagement process named knowledge networks. In this project, knowledge networks are fundamental to building trust, credibility, and the willingness of stakeholders to co-create and implement the TAPs.
