Food system shocks and food insecurity vulnerabilities: introduction to the symposium

The global food system has been subject to a multitude of shocks in recent years, drawing renewed attention to food insecurity vulnerabilities. Extreme weather events, economic crises, a global pandemic and wars have caused significant disruptions, compromising food security for significant portions of the population. Shocks impacting upon food systems bear additional adverse outcomes where populations are already vulnerable to poverty and other social inequalities, and increasingly, shocks are affecting populations not previously considered food insecure. This paper, and the Symposium it introduces, articulates an emerging field of study that explores the dynamic interplay of food system shocks and food security through multiple disciplinary perspectives. The articles in this Symposium address the impacts of and responses to shocks such as weather events and the COVID-19 pandemic and consider these through the theoretical lenses of actor perspectives, governance, and transitions. This Symposium looks beyond the short-term acute event and contributes to a systemic understanding of ‘food shocks’ by reflecting on how enduring and persistent disruptions reverberate through multiple layers of food systems, how they are experienced and addressed across global and local scales, and how they may deeply transform food systems and impact people over time.
