Food Security Definition Measurement and Recent Progress

Although an earlier study counted at least 30 definitions of the term "food security" (Maxwell and Smith 1992), the benchmark understanding of the term is roughly that of FAO (FAO 2001):

Food security is a situation that exists when all people at all times have physical, social, and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.

Under this definition, food security consists of having, on an individual level, the food one needs and wants. This definition is then conventionally subdivided into three main components: food availability, food access, and food utilization. Availability refers to the physical presence of food; access refers to having the means to acquire food through production or purchase; and utilization refers to the appropriate nutritional content of the food and the ability of the body to use it effectively. We explore each of these aspects of food security in the context of climate change below.
