Strategic peace mediation and dialogue efforts to shift conflict systems

When working with or in complex conflict systems, including on dialogue, peace mediation or peace process support, a critical question is how we can best contribute to positive substantive shifts in these systems. FBA’s two thematic units working with dialogue, peace mediation and peace process support have explored these issues during the last few years. During this time, Anita Ernstorfer, an expert in peacebuilding and long-standing FBA consultant, has been a key partner in this conversation.
