Food system sustainability depends, among other aspects, on the resilience of different components of food systems. By resilience, we mean the ability of a food system to withstand stress and shocks, recover, and adapt to change. In this study, we examined the resilience of food systems, firstly, by compiling the risks perceived by different food system actors in the Santa Cruz Department, Bolivia, and the northwestern Mount Kenya Region, Kenyatwo regions that are important to their respective national food supply. Secondly, we evaluated whether and under what circumstances these perceptions translate into adaptive or preventive strategies that benefit food system resilience. Among all actors, the most frequently perceived risks relate to production levels. Further, the many (sometimes contradictory) perceptions of risk and uncertainty among different actor groups do not necessarily translate into adaptation strategies. Reasons for this include structural factors as well as the risk perception paradox, particularly regarding preventive strategies. However, we also observed many implicit strategies illustrating how different actors develop responses within their possibilities. However, most such strategies were insufficient to mitigate, much less to adapt to, the perceived risks. To build resilience, existing innovative policies need to be enforced in both countries. These include disaster risk reduction programs and programs to reduce the vulnerability of marginalized groups who are crucial to food systems, such as smallholder farmers, pastoralists, and food workers.
