    Abstract Impacts and risks from climate change, natural hazards and other shocks do not occur in isolation. As economic sectors and systems become increasingly interconnected, the space in which impacts and risks cascade is expanding. As a result of interdependencies, impacts from hazards, threats or shocks, as well as responses to them, can create cascading impacts throughout systems, leading to consequences that extend far beyond the original threat and sometimes even beyond the region that was originally affected. Understanding the complexity of risks, including possible compounding, cascading and systemic effects, is a key step in reducing and managing disaster risks. This is recognized also in the Sendai Framework for Disaster Risk Reduction. To do this effectively, there is a need to develop tools and methodological approaches that can account for this complexity. This guidance document provides “how to” instructions for the development of Impact Webs, a novel methodological tool which are designed to better understand and characterize complex risks, such as compounding, cascading and systemic risks. In helping to better understand the complex nature of risks, Impact Webs can also provide important entry points for comprehensive risk management.
