Assessing food insecurity strategies across twelve countries from different income levels: a sustainability and food systems perspective

Abstract Achieving Sustainable Development Goal 2 (Zero Hunger) by 2030 remains a persistent global challenge, especially under current overlapping crises such as climate change, economic instability, and geopolitical conflicts. This study critically analyzes the food security strategies of twelve countries across four income groups, as classified by the World Bank: Low-Income (Malawi, Afghanistan, Ethiopia), Lower-Middle-Income (Nigeria, India, Lebanon), Upper-Middle-Income (Maldives, Brazil, China) and High-Income (Canada, Germany, United Arab Emirates). Using a structured narrative review of national policies and programs (2016–2024) sourced from academic databases, government publications, and international reports, we assess the alignment of strategies with the sustainability pillars (economic, social, environmental) and six key agri-food system interventions. Findings show that lower-income countries emphasize social protection and foundational agriculture (e.g., Ethiopia’s safety net improved food security by 30%), while higher-income nations focus on technological and environmental innovations (e.g., Germany aims to reduce nutrient losses by 50% by 2030). However, 10 of the 12 countries are off track, progressing at less than 50% of the rate needed. China (80% SDG2 score), Canada (70%), and Afghanistan (35%) demonstrate the widespread nature of this trend across varying income groups. The study underscores the urgency for integrated, context-specific strategies, enhanced international cooperation, and financing to accelerate progress toward Zero Hunger.
