Abstract
Seed systems in agriculture play an essential role in food autonomy and therefore in resilience of human societies. This chapter focuses on the resilience of seed systems through the study of seed networks involving farmers and other stakeholders. As seeds are living entities, they evolve over time according to the growing environment and production practices. This specificity leads us to consider the resilience of seed networks from two perspectives: through the structural properties of these networks, and through the study of genetic evolution of circulating seeds. We also invite students and scholars to act directly on the resilience of these seed networks by undertaking a collaborative research approach with farmers and other stakeholders like breeders or genebank managers. The co-design of decision support tools based on the network formalism with the actors favors reflexivity, which makes their own operating rules evolve in order to improve the resilience of their system.
