Nature encompasses diverse values, including intrinsic, instrumental, and relational dimensions, which shape human interactions with ecosystems. Understanding local perceptions of these values is a crucial first step in ecosystem service assessments (ESA), ensuring alignment with community priorities. ESA has the potential to enhance disaster risk management (DRM) by providing essential ecological information that is often overlooked, despite the close interconnection between social and ecological systems in disaster contexts. However, the practical integration of ESA into DRM strategies remains limited due to a lack of clear examples and actionable entry points for policymakers. Existing research highlights the need for implementation-focused studies that connect ESA information a with real-world DRM applications. This study addresses the multi-hazard risks faced by Thừa Thiên-Huế province in central Vietnam by exploring how ESA can contribute to innovative, ecosystem-based DRM approaches. The research focuses on identifying entry points for integrating ecosystem service (ES) information into DRM policies, specifically through the 2020–2025 Natural Disaster Risk Management Plan (2365/QĐ-UBND), the province's key policy document outlining priorities and strategies for disaster risk reduction. Using a mixed-methods approach, the study has three specific objectives: (1) identifying the ecosystem values most appreciated by the residents of Huế—whether intrinsic, instrumental, or relational—through household surveys; (2) assessing the capacities of different land cover types to provide ES using a participatory ES Matrix approach; and (3) analyzing DRM policy documents with MAXQDA to identify actionable entry points for embedding ESA findings. Preliminary results suggest that residents prioritize instrumental ecosystem values, such as regulating and provisioning services, which align with local needs for hazard mitigation and vulnerability reduction. The ES Matrix reveals that evergreen broad-leaved forests provide the highest levels of ecosystem services. Furthermore, the policy analysis identifies key entry points for integrating ESA into DRM, grouped across various DRM phases. This study bridges critical knowledge gaps by linking ecosystem service supply with actionable DRM policies in Thừa Thiên-Huế. The findings advocate for the integration of ESA into DRM strategies, enhancing resilience to multi-hazard risks in the region and providing a replicable model for other vulnerable regions globally.

Disaster scenarios play a crucial role in research and preparedness efforts, providing a basis to derive valuable insights into potential future disaster evolvements and impact. Scenarios are composed of events, which can be either hypothetical or derived from dedicated disaster databases that track disasters that have occurred in the past (e.g., https://www.emdat.be/). By leveraging historical data from such dedicated disaster databases, researchers have applied various statistical methods to analyze past events and their complex dependencies [1]. However, since the reality and impact of disasters are increasingly interconnected, involving multi-hazards and cascading effects, a shift towards sophisticated scenario generation methods that can capture these complex dependencies is necessary.

Building upon existing descriptive disaster scenario modeling approaches that utilize combinatorial sequence methods [2,3], we enhance the scenario generation of a disaster framework [4] with the explicit integration of complex-dependencies between hazards. We present how inter-event dependencies, event sequences that have occurred in the past as well as cascading-effects identified in the literature can be integrated into a descriptive disaster scenario generation approach. We conclude with a vision for embedding the proposed dependency-aware descriptive scenario generation approach into the bigger picture of disaster management strategies.

The effectiveness of disaster resilience measures in the context of sustainable development depends on various factors, including government policies and interventions across sectors, community and civil society engagement, information dissemination and mobilisation of resources. It is crucial to consider diverse stakeholders from different disciplines to fully appreciate their integral role for developing and implementing suitable strategies.

Previous studies across various domains highlight the interdependence of scientific outcomes, government policies, and community involvement for sustainable development. However, the linkages of stakeholders and disciplines with the interconnected dynamics of science, policy, and community engagement in disaster resilience is not adequately studied. This underscores the need to understand and document how different stakeholders and disciplines can collectively contribute to disaster resilience and sustainable development. 

The Indo-Pacific region is prone to several disasters, including floods, droughts, cyclones, typhoons, tsunamis, earthquakes, volcanic eruptions, and forest fires. Research tours (supported by Japan Foundation and Australian Institute of International Affairs) were undertaken in Japan, Australia, Fiji, and Tonga by the Indo-Pacific Cooperation Network members, to comprehend disaster resilience measures in these countries. The study employs a systematic literature review and stakeholder consultations in each region to learn about their overall approach to disaster resilience and map key findings against Sustainable Development Goals. It identifies how selected Indo-Pacific regions have integrated transdisciplinary knowledge and sustainability principles into their disaster resilience plans and actions. The study features good practices and investigates key indicators of disaster resilience for cross-disciplinary knowledge creation and coordinated actions directed towards sustainable development in the selected Indo-Pacific regions.

The study results in a guiding framework, indicating the importance of disaster resilience efforts incorporating transdisciplinary knowledge and sustainable development approach. It offers strategic recommendations to enhance disaster preparedness, response and recovery efforts with the framework as a baseline, for the complex science-policy-community nexus. The study serves as a valuable reference for Indo-Pacific regions seeking to embed transdisciplinary knowledge into policies and actions, ultimately improving access to resources, support mechanisms, infrastructure, and communication which empower communities for disaster resilience.

The explosion of the Deepwater Horizon, an oil tanker of BP, caused a large amount of crude oil spill in 2010. In South Korea, two large-scale marine pollution accidents occurred: 'sea prince oil spill accident' off the coast of Busan in 1996 and 'Hebei Spirit oil spill accident' off the coast Taean in 2007. Marine accidents during transport cause widespread direct and indirect damage, such as human damage, property losses, economic damage, and environmental pollution. Especially, in case of large-scale oil spill occurs, it has a serious adverse effect on the environment around the affected area, such as population outflow, regional economic downturn, and intensification of community conflict. The probability of marine pollution accidents is increasing due to changes in the trade environment, such as the expansion of world seaborne transportation volume, as well as enlargement and speeding up of ships. In addition, the potential risk of marine pollution accidents is increasing due to the expansion of marine areas use, such as the installation of offshore plants, and the deterioration of weather conditions caused by climate change. In order to mitigate the damage from oil spills during maritime transportation, it is necessary to prepare safety management strategies based on risk prediction. The purpose of this study is twofold: ⅰ) to propose a risk estimating approach of oil spill accident by constructing a probabilistic risk matrix (4×4) using the Markov chain process. ⅱ)  to compare the risks by sea area, including major ports in South Korea: Central, West, South, East, and Jeju. Analysis data was used with detailed marine pollution accidents provided by the Korea Coast Guard. 84 months of accident data were collected over 7 years from 2017 to 2023. In this study, the risk matrix proposed by the International Maritime Organization (IMO) was used, and the levels of the risk matrix was divided into 4: attention, caution, alert, and serious, as specified in the crisis alerts management manual of marine pollution accidents in South Korea. The risk of each sea area could be quantified by comprehensively considering the monthly occurrence frequency of accidents and the volume of oil spills. In addition, by applying the probability value through Markov chain process to the risk matrix, the uncertainty of the risk analysis data could be reduced and risk level could be classified more clearly and quantitatively based on accident data. The results can be used as basic data for decision-making on the allocation of resources and budgets for policies to prevent marine pollution accidents.

The Canary Islands are the only Spanish territory exposed to volcanic risk. The recent eruption on La Palma has highlighted the exposure and vulnerability of our society to volcanic hazards. As a result, the Tajogaite eruption (2021) should mark a turning point in our management of volcanic risk in the Canary Islands, despite the progress made in the last 25 years to reduce volcanic risk in the archipelago.

This new direction should be adopted through a Canary Islands Volcanic Risk Reduction Strategy, an operational tool that serves as a framework for addressing and responding to the challenges faced by the Canary Islands due to volcanic risk. It would also serve as a driver and coordinator of various sectoral policies and as a means of raising awareness among citizens, businesses, and administrative bodies. Three basic ideas or pillars (scientific knowledge, public engagement, and consensus) will serve as the foundation for the development of this important tool.

Citizen participation would involve inviting all sectors of society that can and should play a role in volcanic risk management (scientists, public administration authorities, politicians, emergency experts, land-use planners, journalists, etc.). The idea behind broad citizen participation is that each sector can debate and provide its perspective on volcanic risk management. The strength of this debate, through a SWOT analysis, lies in the fact that only those observations emerging from consensus can be described.

In summary, our society needs a Canary Islands Volcanic Risk Reduction Strategy because volcanic risk is increasing in our archipelago.

This presentation reflects on the stakeholder engagement and knowledge co-production process across the Pilots in the MYRIAD-EU project, which aims to provide useful tools and approaches for creating forward-looking disaster risk management pathways that assess trade-offs and synergies across sectors, hazards, and scales. Knowledge co-production in MYRIAD-EU focused on two dimensions: the internal collaboration between project partners and the iterative co-production of knowledge between researchers and stakeholders. In this talk, we briefly introduce the framework and focus on the co-production steps leading to the finding of two focus group (FG) sessions takin place in 2023 and 2024. In these sessions, stakeholders from Scandinavia, Veneto, the Danube, the North Sea, and the Canary Islands actively participated in testing and implementing several methods, tools, and frameworks.

FG1 focused on initial stakeholder interactions, highlighting key challenges such as the rising awareness of climate change impacts, including extreme precipitation events in Scandinavia and the multi-risk nature of past storms in Veneto. Feedback from these sessions underscored the importance of clear communication, sectoral knowledge exchange, and social justice considerations in addressing climate resilience. The collaborative nature of FG1 was reflected in positive stakeholder engagement, with participants providing valuable input for scenario co-creation and testing.

Building on FG1, FG2 sought to deepen sectoral integration and refine the tools developed in the project. While securing stakeholder engagement required continuous efforts from Pilot Leads, the integration of sector-specific experts helped further co-develop disaster risk management pathways. In Veneto, the discussion centred on the Vaia storm, providing a better understanding of cross-sectoral impacts and management actions. Challenges, such as stakeholder fatigue in Scandinavia and mismatched expectations in the Canary Islands, highlighted the ongoing need for adaptable engagement strategies and clear communication of project capabilities.

The use of co-production tools, including structured interviews, interactive surveys, participatory mapping/systems thinking, scorecards, storylines and scenario-building facilitated discussions and provided valuable opportunities for stakeholders to directly influence the development of tools and strategies for disaster risk management. These sessions revealed the importance of iterative feedback, flexibility in engagement, and the need to continuously adapt methods to ensure effective collaboration. The findings underscore that successful knowledge co-development requires the integration of diverse stakeholder knowledge, effective communication of project capabilities, and adaptable co-production strategies tailored to the specific regional and sectoral contexts.

This poster explores the use of serious games as a comprehensive approach to disaster risk reduction and resilience, bridging gaps between physical and social sciences, policy, and practice amidst the complex and uncertain context of climate change. Developed under the DIRECTED project in collaboration with local stakeholders, these games integrate diverse technical and social science perspectives by combining DIRECTED Data Fabric scenarios with Speculative Design. This integration enhances our capacity to mitigate and adapt to complex disaster risks while promoting interdisciplinary approaches to disaster risk management and climate change adaptation.

Key Objectives:

• Enhancing understanding of risk governance contexts, challenges, and opportunities for integrating climate change adaptation and disaster risk management amidst uncertainty.
• Developing "future-making" skills that translate gaming insights into real-world applications, equipping stakeholders to work across disciplines to tackle complex challenges.

The poster will share insights from our scenario-based, gamified Tabletop Exercise, illustrating their potential to address bureaucratic hurdles, disciplinary silos, and unclear responsibilities. With the DIRECTED Rhein-Erft Real World Lab, we co-created a speculative scenario based on model data from the 2021 floods in German federal states—particularly North Rhine-Westphalia—enhanced with projections of future climate change impacts. Using this case study, we will demonstrate how gameplay can enhance imagination, foresight, and collaboration. By exploring participants' contexts and constructing meaning around "what if?" scenarios—rooted in the unique experiences and perspectives of real people—these exercises inspire innovative solutions. Furthermore, they introduce new ways of working that support resilient pathways for risk governance and climate adaptation.

This transdisciplinary approach highlights the role of serious games in fostering dialogue, sparking creativity, and generating actionable insights across science, policy, and practice to address multi-risk challenges.

Effectively assessing the impact of risk communication efforts is a significant challenge in the field of natural hazards. In this context, we present an evaluation framework used to measure the effectiveness of Safe Haven – Landslides, a serious game designed to raise awareness and promote understanding of landslide risk.

To quantify the game’s impact, we developed pre- and post-experience questionnaires aimed at assessing participants’ knowledge, attitudes, and understanding of landslide hazard and risk before and after engaging with the game. The questionnaires included a series of questions designed to measure changes in risk perception, comprehension of mitigation strategies, and overall awareness of landslide dynamics and management strategies.

The results were analysed by comparing pre- and post-game responses, providing valuable insights into how the game influences participants’ understanding of landslide risks. Early findings suggest significant improvements in knowledge retention and a deeper understanding of the highlight the potential of game-based approaches in promoting proactive risk management and resilience.

This study contributes to the ongoing discussion on how to effectively evaluate the impact of risk communication initiatives. It also proposes a framework for assessing the effectiveness of educational and outreach activities aimed at enhancing public awareness of natural hazards.
