This webinar tackles one of the greatest challenges of our time. Agriculture, food systems and nutrition combine at the nexus of a global crisis of malnutrition, food insecurity, and food quality. These issues have huge social and economic costs. While the crisis is acute in many of the low- and middle-income countries of the developing world, it is by no means limited to such countries. Every country is suffering the consequences of this significant medical and public health challenge, whether from undernutrition, overweight/obesity, micronutrient deficiencies or disease burden stemming from food quality, food and water contamination and poor food options and choices. The challenge encompasses an intersectoral, multi‐dimensional problem that interplays between government, business/industrial, household and individual decision‐making. Additionally, agri‐food, health, and environmental systems all determine access to services and resources. Rife with these complexities, the issues are pressing and require urgent attention.
