Stakeholder-driven risk prioritisation for Belgium’s first climate and biodiversity risk assessment

Case

The first Belgian Climate Risk Assessment report, with stakeholder engagement guided by Möbius, identifies priority risks and provides scientific insights for crisis and adaptation policy.

Strategic challenge

Belgium is already feeling the effects of climate change and biodiversity loss. Floods threaten homes, farmland, and infrastructure. Heatwaves put pressure on public health, especially for elderly and vulnerable groups. Periods of drought affect agricultural production and drinking water supplies. At the same time, biodiversity loss is weakening ecosystem services such as pollination, water purification, and soil fertility. 

These risks not only impact the environment but also the economy, public health, social cohesion, and even national security. 

To act proactively, the federal Climate Risk Assessment Center (CERAC) commissioned the first-ever national climate and biodiversity risk assessment. The project was carried out by a consortium of ICEDD, VITO, Ramboll, ULiège, and Möbius, in close cooperation with CERAC. 

The aim of this study:

  • Develop a comprehensive picture of the risks associated with 2°C, 3°C, and 4°C of global warming.
  • Identify knowledge gaps and set priorities.
  • Provide scientifically sound input to the National Security Council and future climate adaptation strategies.
This first national climate and biodiversity risk assessment required bringing together a very diverse group of experts and stakeholders. Möbius ensured a smooth and well-organised consultation process, which enabled constructive dialogue and provided a strong basis for the study’s conclusions and next steps.

A three-step methodology

The study covers a wide range of societal systems: ecosystems (marine, coastal, freshwater, soil, and forest), the food system, infrastructure and buildings, health and social cohesion, as well as the economy and financial sector.

The strength of this project lies in the combination of rigorous scientific analysis and a broad participatory process. Möbius played a key role in designing and implementing the stakeholder engagement process – from recruiting participants to facilitating and animating the workshops.

 

Step 1: Risk Identification  

 The study began with a literature review to map all potential climate and biodiversity risks for Belgium. Based on this analysis, a selection was made of those risks most relevant to the Belgian context and requiring further investigation. 

Step 2: Risk Analysis

 The selected risks were then examined in depth. A comprehensive literature review characterised their severity, likelihood, and our policy readiness. Interviews with scientists and policy experts were conducted to validate and enrich the findings, ensuring the analysis was both scientifically robust and policy relevant.  

Step 3: Risk Prioritisation

Risks were prioritised using two explicit criteria: risk severity and policy readiness. This helps the National Security Council and policymakers to determine where action is most urgently needed. In this final phase, stakeholder engagement was key. Möbius, together with the CERAC-team and with the support of ULiège, designed and facilitated a carefully managed consultation process, bringing together academic experts, representatives of affected sectors, and key end users such as policymakers and security actors.  

Through interactive workshops and a Delphi survey, a broadly supported list of priorities was established, ensuring the most urgent risks were clearly identified and collectively acknowledged. 

Results

  • National risk analysis: a scientifically grounded and widely acknowledged overview of Belgium’s priority climate risks. Discover the Belgian Climate Risk Assessment here.

  • Policy-relevant insights: initial recommendations serving as input for the National Security Council and future adaptation plans.

  • Strong stakeholder engagement: a successful participatory process bringing together science, policymakers, security actors, and affected sectors.
