Whereas previous chapters have focused on ECOWAS and AU efforts to actively manage conflicts in their respective regions, this chapter analyzes other, more general objectives that they have pursued simultaneously during conflict intervention, linked to specific spatial-political projects and based on particular spatial imaginations. Therefore, the chapter, first, reflects upon two of the main spatial imaginations that have triggered, framed and guided interventions in West Africa, which have been connected to specific regional and trans-regional security concerns, namely ‘political instability’ and ‘narco-terrorism’. Second, looking through the prism of interventions in Guinea-Bissau, the chapter analyzes how actors at ECOWAS, the AU and the EU have sought to develop and consolidate specific regional security policies, thereby formatting their own regional spaces (i.e., ‘internal’ formatting) or the regional spaces of other organizations (i.e., ‘external’ formatting). In this respect, it traces the emergence of certain policy processes at these organizations across different conflict situations.
