The UNCHAIN project utilizes an impact chain method to improve climate change risk assessments and adaptation actions. In a case study in Halmstad, Sweden, researchers adapted this model to explore how multiple hydrometeorological hazards interact with pre-existing vulnerabilities to create cascading disruptions across critical infrastructures and vital societal functions, potentially generating new vulnerable social groups. The process emphasized the co-production of knowledge, integrating stakeholder expertise from sectors such as water services, urban planning, and risk management through a participatory, iterative approach based on five selected modules of the impact chain framework.
