“…The question that guides this study is: How has boundary infrastructure evolvement, and the interaction between boundary infrastructure elements, played a role in the transition from the spot market to vertical coordination in BPP? This question connects to recent efforts to further unravel how interactions between science, policy, and practice promote coordination, close down contingency, and impact long-term changes in agri-food sectors (Chabbi et al, 2017;Nel et al, 2016;Sarkar, Poon, Lepage, Bilecki, & Girard, 2018;Zougmoré et al, 2019). Moreover, this kind of deeper understanding of boundary infrastructures is critical for debates on transformation towards sustainable food systems (e.g., Lamine, 2011;Ingram, 2015;Gaitán-Cremaschi et al, 2019), as it gives insights into transition dynamics.…”
