The effective implementation of NBS is still hampered by several
barriers. Among the others, this work focuses on the collaboration
barriers. NBS design and implementation could be conceptualized as a
collaborative decision-making process, involving various
decision-makers. Nevertheless, differences in problem framings may turn
the multi-actors decision-making into a controversial and often futile
process, leading to barriers hampering the NBS design and
implementation. Contrarily to most of the works on conflict management,
mainly based on the reduction of the divergent viewpoints, this work
assumes that ambiguity is ineradicable in complex decision-making
processes. Therefore, the work demonstrates that enhancing the
effectiveness of the networks of interaction, through the implementation
of networking interventions, can contribute to reducing the level of
conflicts and, thus, enabling the NBS implementation. An integrated
SNA-FCM method was developed to this aim and implemented in the Medina
del Campo case study, one of the demo-sites in the NAIAD project.
