# Workshop report—Vulnerability in multi-hazard risks: Addressing its complexity and dynamics

## TL;DR

Researchers met to discuss how to better understand and address complex risks by integrating different fields and improving data sharing.

## Contribution

The paper outlines three key areas for advancing vulnerability research through interdisciplinary integration and data interoperability.

## Key findings

- Interdisciplinary integration is needed to bridge epistemological divides.
- Data interoperability can enhance robustness and policy relevance.
- Vulnerability assessments should balance complexity with local context.

## Abstract

In November 2025, an interdisciplinary group of vulnerability researchers met in Munich and identified three challenge-opportunity clusters: first, overcoming epistemological divides to enable meaningful interdisciplinary integration. Second, the interoperability of data, methods, and evidence can strengthen robustness and policy relevance. Third, vulnerability assessments must adopt fit-for-purpose levels of complexity that preserve local context while enabling cross-scalar translation. This backstory is a call-to-action to accelerate the transition of the field toward robust, policy-salient, and socially legitimate integrative and interdisciplinary research.
