Abstract

Moving towards a more holistic approach to disaster risk management, in which a multi-hazard and multi-risk approach is central, offers many opportunities to increase society's resilience. In 2022, we presented a research agenda of six points that could contribute towards this paradigm shift. In this perspective paper we synthesise key learnings from the MYRIAD-EU project – which ran from September 2021 to December 2025 – reflecting on progress and challenges faced in pursuing this research agenda, and share perspectives that may help to further improve multi-hazard and multi-risk assessment and management. Going forward, we point to several avenues for continued scientific research that we feel would benefit the field: continue the mainstreaming and mutual understanding of concepts and definitions; continue developing a strong evidence base of how dynamics in hazard, exposure, and vulnerability in space and time shape multi-risk; further developing methods for providing both current and future multi-hazard and multi-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 and multi-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. We suggest concrete ways in which we believe these topics can be addressed in future years and decades.
