Engaging stakeholders in construction and validation of Bayesian belief networks for groundwater protection

A Bayesian belief network (BN) for farming contracts has been constructed and validated with direct co-operation and in dialogue with stakeholders. On the one hand, BN’s can create space for an open dialogue with stakeholders due to the flexibility of the decision support tool. This allows factors (nodes), associations (directed links) and probabilities to be adjusted and validated throughout the process and based on inputs from all involved stakeholders and experts. On the other hand getting stakeholders to understand and accept the idea behind BNs is demanding. Especially the required probability assessments are not easy to understand by stakeholders.
