The term food security originated in international development literature in the 1960s and 1970s. Over time, a large number of different definitions of food security have been proposed. FAO (2015) defined food security as “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”. According to this definition, food security is comprised of four components i.e. availability, accessibility, utilization and sustainability. Food insecurity or lack of food security situation is due to the nonexistence or inadequacy of any of the above mentioned four conditions at various levels (i.e. household, regional or national). When food intake is consistently inadequate and insufficient to meet the dietary needs of people it is called severe food insecurity or hunger (FAO, 2015). Despite the recent decrease in the number of undernourished people around the world, still, about 795 million people (as shown in figure 1) are food insecure. From these 795 million, 780 million are from developing regions of the world. Situation is even worse in Asia and Africa where 511.7 million and 232.5 million food insecure people live respectively (FAO et al., 2015). Figure 1. Worldwide distribution of food insecurity.
