The 1996 World Summit agreed that food security represents “a situation that exists when all people, at all times, have physical, social and economic access to sufcient safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life” (Barrett, 2010). This denition comprises complex targets, because food security means not only to have food available through sustainable production but also to have access to food under different conditions. Table 14.1 explains the complex issue of food security, distinguishing between availability/sustainability and accessibility.
