Global Food Trade, Shocks, and Migration

In this course, we examine the complex interdependencies between global food trade systems, climate-related and socioeconomic shocks, and human migration patterns. Together, we'll explore how disruptions propagate through international food networks, analyzing these systems through the lenses of agricultural economics, climate science, and geopolitics. We will investigate how various shocks—from climate extremes and armed conflicts to market volatility and pandemics—impact food security and trigger population movements across diverse regions and scales. Throughout the semester, we'll pay particular attention to climate change as a threat multiplier that intensifies existing vulnerabilities in our global food systems. By combining data analysis, case studies, and theoretical frameworks, we'll develop a nuanced understanding of the food-climate-migration nexus that shapes our modern world. This multidisciplinary approach will enable us to examine concepts of resilience and evaluate diverse solutions for strengthening food systems' ability to absorb shocks, from diversified production and redundant supply chains to adaptive governance mechanisms and transformative policy interventions that enhance robustness across scales. We will specifically investigate how different metrics of resilience—including redundancy, diversity, modularity, and connectivity—can be operationalized in food trade networks to reduce vulnerability to cascading failures that often trigger migration responses. Through quantitative analysis and case studies, we'll assess how strategies such as regional food reserves, alternative distribution channels, and early warning systems affect both food security and human mobility patterns. This integrated approach allows us to explore interventions that simultaneously strengthen food systems and provide migration-sensitive adaptations, recognizing that human mobility itself can be both a vulnerability and a resilience strategy in the face of food system disruptions.
