At the heart of the sustainable development goals (SDGs) lie food systems, which have substantial impacts on nutrition and planetary boundaries worldwide. The COVID-19 pandemic has worsened the situation, with 702-828 million people suffering from hunger, up by ~150 million people post-pandemic, and over 2 billion people having micronutrient deficiencies. Food systems are also causing the Earth to exceed its limits, as they are accountable for a third of global greenhouse gas emissions, more than half of global habitable land use, and over 70% of freshwater consumption. Hence, the urgency to transform the food systems have been highlighted by the academic and intergovernmental circles alike. By linking highly disaggregated agricultural and seafood product data of global production and bilateral trade with those of food composition databases and dietary guidelines, I will walk through spatiotemporal trends in global food systems' ability to meet the SDG2 – Zero Hunger. Building on SDG-inspired scenarios, such as SDG12 – Responsible consumption and production and SDG13 – Climate Action, I will also explore options to nourish future populations while minimizing environmental impacts through the use of linear programming. Finally, I will conclude by discussing the next steps for a more comprehensive and dynamic assessment of nutrition-sensitive and sustainability-oriented food interventions to achieve multiple competing SDGs.
