Short summary
Impact Webs are a conceptual risk modelling tool designed to better understand and characterise complex risks. Understanding the complexity of risks is a key step in reducing and managing disaster risks. This paper outlines the rationale for Impact Webs and the steps for their co-creation and use. Impact Webs allow for an in-depth analysis while accounting for interactions within the systems in which they exist. They can be used to provide guidance for risk management options.
