D6.5 Online repository of storylines on multi-risk decision-making

The MYRIAD-EU project has realised the value of storylines to use narratives of past or plausible future events to explore and characterise cause-and-effect relationships between risk drivers and impacts within a system. Storylines can be purely qualitative or include semi- or fully quantitative components enabling a holistic examination of a system that can account for non-quantifiable elements and high levels of uncertainties. Storylines can be used to understand why a system responded in a particular way to an event and explore how modifying elements within a system could change the outcome. This can include how decisions made can impact the system and the unfolding of events. MYRIAD-EU has developed a storyline framework with guiding questions to support pilot teams in applying a storyline approach to break down the complexity and examine the interacting nature of multi-risk systems through analysis of past or plausible future events. The storylines approach has been used by MYRIAD-EU pilot teams in several different ways: (1) support their understanding of the complexities of multi-hazard, multirisk events in their regions; (2) facilitate cross-sectoral engagement with stakeholders on multi-hazard, multi-risk decision-making; (3) facilitate communication of complex relationships to raise awareness of multi-risk events; and (4) support drafting of forwardlooking decision-making pathways for plausible future events. The storylines are visualised using the Esri ArcGIS StoryMaps tool shared in an online repository hosted on the MYRIAD-EU dashboard.
