**2. Food security terminology**

Food security is a multidisciplinary and multisectoral approach; despite its importance, food security has many meanings and operationalization. In fact, a vast range of terminology has been used to debate, measure, and intervene in food security. A wide variety of academic fields like economics, nutrition, agriculture, anthropology, public policy, and sociology, as well as a large number of governmental and nongovernmental as well as national and international agencies, have been actively involved within it. The concept of food security is stated in various contexts, each of which has been accompanied by its particular jargon. Hunger is also associated with food insecurity; the concept of hunger is probably so emotionally intense [8].

The definition of food security is described in the World Food Summit, 1996, which is being commonly used. According to it, food security is accomplished when all people have economic and physical access to a safe, nutritious, and adequate amount of food to accomplish their dietary requirements as well as food choices for a healthy life [11]. According to the definition, food insecurity occurs when one or more of the above conditions are not met. Food insecurity is categorized into three types: chronic, seasonal, and temporary food insecurity. The most severe form is chronic food insecurity, whereas transitory food insecurity is the least severe [12].

People sometimes use the terms "food security" and "nutrition security" synonymously, but the definitions of each are much different. Food security is necessary for nutrition security, but it is not enough. Aside from food, nutrition security also looks at care, health, and hygiene practices. According to FAO, nutrition security is stated as when everyone in a household has easy access to a healthy, well-balanced diet, a clean environment, and good health services and care. This makes sure that everyone is healthy and able to live a good life [2].
