In pursuing a sustainable future, a circular economy has emerged as a pivotal framework, particularly within water management. The CIRSEAU cluster, an alliance of EU- funded research projects, has been at the forefront of this movement. The projects designed a set of innovative tools, games, and applications to foster stakeholder involvement and promote sustainable water practices. These were demonstrated at the Making waves: Tools and games for stakeholder engagement on water, sustainability and the circular economy on 5 July 2024 as part of the Ecsite Conference in Ljubljana, Slovenia. The workshop was jointly organised by the CIRSEAU Cluster working groups on stakeholder engagement and communication.

This knowledge capsule consolidates these resources, providing a comprehensive toolkit for policymakers, researchers, and practitioners. The capsule includes an overview of each project, detailed descriptions of the tools and applications developed, and findings from these initiatives.

It is important to emphasise that the tools and applications are designed to be adaptable and should be employed in other contexts where stakeholder engagement is a priority.
