Strategic environmental risk management and planning must account for uncertainty and complexity, necessitating methods that facilitate scenario development under incomplete knowledge. This paper introduces a participatory modelling (PM) -based knowledge co-production and strategic planning approach utilizing one type of AI tool - Bayesian Networks (BN) - for systemic scenario development, analysis and resilience-building. The developed method integrates diverse perspectives and expertise of participants through a structured BN model, enabling co-imagination and -construction of causal pathways, translating them into probabilistic dependencies, and diagnostically identifying potential leverage points for strategic resilience-increasing actions. We illustrate and test this approach using a case study of a chemical transportation accident in an urban environment, documenting the participatory process and the algorithm to translate the participants' thinking to a computational BN. Through content analysis of transcribed audio recordings, we demonstrate how the exercise helped uncover "reflexive unknowns" - previously unrecognized threats that became apparent and thinkable only through the collaborative modelling process. An example of such a reflexive unknown in our case exercise is the prospect of toxic rainfall following the accident and its short- and long-term implications for the built and natural environment. This was a blind spot in the thinking of the participants, and it appeared and became a scenario to be acted upon only as a result of the process of collective cross-sectoral causal thought represented with a BN model. The paper provides a detailed description of the developed participatory BN approach and methodology, enabling their applicability in various contexts. Through a qualitative analysis of the exercise's implementation, the article also demonstrates how the approach fostered collective, iterative reflection, generating new insights to socio-environmental resilience.
