In the Vomano pilot application, some stakeholders (local authorities, National Park representatives, and
river anglers) were directly involved in the development of the tool and in the determination of different

order to evaluate the effectiveness of the approach. In general one objective of the MERIT project will
be to develop techniques to encourage and enable full stakeholder involvement in the construction of
BBN and, ultimately, in the decision making process.
