Revitalising the way the social sciences question agri-environmental governance, this book introduces "the everyday governance approach" as a means to improving the sustainability of agriculture and food systems. The "everyday" refers to localised practices, specific networks, and practical norms that emerge in a process of interaction, translation, and reinterpretation. The authors build this approach on assemblage thinking and theory, which focuses on the collective production of the social through complex sets of connections. For this reason, assemblage thinking becomes a particularly productive guide in exploring how everyday governance is co-produced in the interaction between numerous social processes involving a diversity of actors and instruments. The authors navigate between original and contrasting case studies from Switzerland, Indonesia, and the European Union in order to reorient attention to the transformative nature of governance, which they locate along four different dimensions of the everyday: (1) the interdependence of instruments within a wider governance assemblage; (2) the uncertainty and unpredictability of effects in agri-environmental governance; (3) the distributed nature of agency and its implication for power relations; (4) the importance of capacities in the transformation of agri-food systems. This book calls for a redesigning of agri-environmental governance that should move away from the setting of fix and precise objectives and solutions, and rather aim for a consolidation of sound foundations on which desirable futures can emerge. The book will be an essential read for students and scholars interested in sustainable agriculture and food systems, governance modes and approaches, and sustainability more broadly.
