ABSTRACTAlthough critical studies on peace and conflict studies have addressed the topic of knowledge production and peacebuilding, this is not a highly discussed issue in the literature. There is no unique or unambiguous conceptual framework to analyze this topic. This article shows conceptual elements that must be considered to understand the interaction between local and scientific knowledge in research projects on peace and peacebuilding; and reflects on what types of problems emerge when local and expert knowledge interact within the context of international cooperation projects. Based on the evidence collected during one workshop with Colombian researchers and the analysis of fifty research proposals funded by the German Colombian Peace Institute (CAPAZ) between 2017 and 2021, this article identifies topics, methodologies and products that suggest the existence of hybridization and co-production practices of knowledge when research on peacebuilding and conflict is designed and conceived.
