“Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life” these words were given to define Food security at the World Food Summit in 1996 held at the Food & Agriculture Organization (FAO) headquarters in Rome, Italy.
According to this broadly used definition, food security relies on the following pillars: availability which consists in having enough supply of suitable food on hand. The second pillar on which food security relies is access, which means having sufficient sources of income or other resources to access food. The third pillar is utilization, which means having a healthy diet and the ability to consume and utilise nutrients. The last pillar is stability, which relies on having access to enough equals food secure and no one should run the risk of going without food as a result of unexpected shocks or cyclical events.
