Purpose: Learning and innovation networks for sustainable agriculture (LINSA) are considered drivers of innovation towards a more sustainable agri-food system. However, sustaining long-term funding remains a challenge for many networks. This paper aims to provide a comprehensive conceptualization of how funding relates to LINSA continuation and suggests a classification of relevant funding instruments. Design/Methodology/Approach: Being purely conceptual, this paper combines perspectives of strategic management and nonprofit finance with empirical insights from innovation network literature to develop a conceptual framework on LINSA funding. Findings: The conceptual framework suggests that thriving LINSA require both an appropriate funding mix, which corresponds with the benefits provided, and an anticipatory utilization of financial resources to build and maintain relevant intangible resources. The availability of funding instruments which incorporate these findings is crucial for successful LINSA. Practical Implications: The conceptual framework provides guidance to practitioners and policy makers who reflect on appropriate strategies and instruments for LINSA funding. Theoretical Implications: By integrating perspectives from different disciplines, namely the resource-based view and the benefits theory of nonprofit finance, this paper contributes to an increased understanding of funding in network organizations. Originality/Value: This is the first paper to offer an explicit conceptualization of how funding relates to LINSA development. It also provides a classification of relevant funding instruments.
