Definition - What does Food Security mean?
Food security refers to the supply of food and to what extent it is accessible to individuals. For food security to exist, adequate food supplies must be available at all times without severe fluctuations in prices that would make foods inaccessible to many individuals.
Safeopedia explains Food Security
If we do not have an adequate supply of foods that are accessible and not priced beyond the reach of consumers, malnutrition and its attendant diseases will become prevalent. Food security can be said to exist when enough safe and nutritious food is available to all. The US government has observed that food security also implies the ability to overcome or circumvent any disruptions in the supply of certain foods.
