Evolution of systems approaches to agricultural innovation: concepts, analysis and interventions

Over the years, there has been an evolution of systemic thinking in agricultural innovation studies, culminating in the agricultural innovation systems perspective. In an attempt to synthesize and organize the existing literature, this chapter reviews the literature on agricultural innovation, with the threefold goal of (1) sketching the evolution of systemic approaches to agricultural innovation and unravelling the different interpretations; (2) assessing key factors for innovation system performance and demonstrating the use of system thinking in the facilitation of processes of agricultural innovation by means of innovation brokers and re fl exive process monitoring; and (3) formulating an agenda for future research. The main conclusion is that the agricultural innovation systems perspective provides a comprehensive view on actors and factors that co-determine innovation, and in this sense allows understanding the complexity of agricultural innovation. However, its holism is also a pitfall as it allows for many interpretations, which complicates a clear focus of this research fi eld and the building of cumulative evidence. Hence, more work needs to be done conceptually and empirically.
