Mapping food security in OECD countries: Clusters, insights and policy strategies

Abstract This study employs two-step cluster analysis on Global Food Security Index (GFSI) data for 32 OECD countries (2012–2022) to identify clusters and assess key food security components: affordability, availability, quality and safety, and sustainability. The findings reveal stark disparities in economic access, agricultural infrastructure, and political commitment to food security. Amid escalating threats from geopolitical conflicts, inflation shocks, and climate change, this research is urgent. It highlights vulnerabilities and offers strategic recommendations to policy makers for bolstering resilience and addressing unique challenges. These insights aim to guide more effective and timely food security policies in a rapidly destabilizing global landscape.
