Purpose: The paper explores the role of boundary work and boundary objects in enhancing learning and innovation processes in hybrid multi-actor networks for sustainable agriculture ({LINSA}).Design/Methodology/Approach: Boundary work in {LINSA} is analysed on the basis of six case studies carried out in {SOLINSA} project under a common methodology. In developing typologies of boundary work and objects, a grounded approach is used.Findings: {LINSA} analysis demonstrates the dynamic character, diverse forms and multiple functions of boundary work and objects in three domains: learning, innovation, and sustainability. Addressing specific types of goals and actors leads to specific types of boundary work and boundary objects. Context-appropriate boundary work allows aligning differing actor attitudes, gaining increased external support, and developing {LINSA}. The concepts of boundary work and boundary objects are relevant in a broad range of divergent {LINSA} settings. Boundary work has its limitations, but its facilitation supports reaching {LINSA} goals.Practical Implications: The paper proposes recognising context-appropriate forms of boundary work and skilful use of emerging boundary objects to both promote internal consolidation of {LINSA} and effective external communication to foster learning and innovation for sustainability.Originality/Value: The paper provides insights into the forms, dynamic and outcomes of boundary work in {LINSA} in three key domains: developing shared knowledge base, co-producing innovation and negotiating sustainability.
