Food security refers to the availability of food and one’s access to it. A household is considered food-secure when its occupants do not live in hunger or fear of starvation. Food availability, food utilization, and food access are the principle variables that define household food security and should guide interventions:
Sufficient quantities of appropriate, necessary types of food from domestic production, commercial imports, or donors, are consistently available to individuals, are in reasonable proximity to them, or are within their reach.
Individuals have adequate incomes or other resources to purchase an appropriate food needed to maintain the consumption of an adequate diet and nutritional level.
Food is properly used, and many suitable techniques are employed for storage. At the global level, Hunger results from political and economic inequality, environmental degradation, unjust trade policies, inappropriate technology, and other factors depending on local context.
