Availability is the pillar that addresses whether there is enough food in the system to meet needs by looking at how much is produced and how it is moved to where people live. It captures the physical presence of food in markets and households, determined by domestic production, imports, storage, and the efficiency of distribution networks. When production is strong and infrastructure and logistics are good, food is physically available to people; when production falls or roads, ports, or storage fail, the amount of food that can reach consumers shrinks, even if people have money to buy it. The other pillars describe different barriers: access is about the ability to obtain food (economic and physical access), utilization covers how the body uses the nutrients from food and whether they are safe and nutritious, and stability concerns the ability to maintain access and availability over time despite shocks. So the statement about physical presence through production and distribution points to availability.
