The Risky Cities Toolkit is a practical resource that supports policymakers, practitioners, researchers and communities to facilitate constructive conversations about flood risk and coastal erosion. Developed through the University of Hull’s AHRC-funded Risky Cities project (2020–2023), it brings together tested creative and participatory approaches—such as public art, exhibitions, theatre, writing, textiles, zines, mapping, archives, serious games and digital tools—to build trust, amplify lived experience and strengthen community-led resilience. The toolkit sets out core principles for ethical and trauma-informed practice, scalability and flexible monitoring and evaluation. Designed to be transferable it provides guidance, examples and evidence to support inclusive engagement in a range of water-related and environmental contexts.
