Major challenges in urban governance concern interlinking food, water and energy systems, making these linkages understandable to all stakeholders (government, science, business, and citizens), and facilitating cooperation and knowledge exchange among them. The project titled "Creating Interfaces" will address these challenges by developing and testing innovative approaches for local knowledge co- creation and participation through Urban Living Labs in three mid-size cities on water: Tulcea, Romania, Wilmington, USA and Slupsk, Poland. Complemented by previous research and a citizen science toolbox, these Labs comprise a user-defined co-creative approach where research questions, problems, and solutions are decided and implemented with stakeholders themselves.
