Four Elements of Food Security

Food availability – The availability of sufficient quantities of food of appropriate quality, supplied through domestic production or imports, including food aid.

Food access – Access by individuals to adequate resources – entitlements — for acquiring appropriate foods for a nutritious diet.

Utilization – Utilization of food through adequate  diet, clean water, sanitation and health care to reach a state of nutritional well-being where all physiological needs are met.

Stability – To be food secure, a population, household or individual must have access to adequate food at all times. Stability is thus needed in both availability and access.
