Reducing Risk Together: moving towards a more holistic approach to multi-(hazard-)risk assessment and management

Building on insights from the MYRIAD-EU project, which ran from 2021-2025, we reflect on the advances and challenges made in terms of moving towards a more holistic approach to disaster risk management, in which a multi-(hazard-)risk approach is central. We synthesise advances made in terms of definitions, frameworks, data, tools, and applications, and reflect on how knowledge was co-produced within the project. Based on our experiences, we outline several avenues for continued scientific research: continue the mainstreaming and mutual understanding of concepts and definitions; continue developing a strong evidence base of how multi-(hazard-)risk both shapes, and is shaped by, risk dynamics over space and time; further developing methods for providing both current and future multi-(hazard-)risk scenarios; increasing the availability of appropriate, solutions-oriented, usable tools; more explicitly including equity issues and equitable disaster risk reduction and adaptation; continue extensively testing and coproducing multi-(hazard-)risk knowledge in in-depth case studies; supporting the development of Multi-Hazard Early Warning Systems; and strengthening opportunities for Early Career Researcher leadership and empowerment within project structures.
