Theoretically, improved food security can be achieved through (a) increased availability – by extending staple food production area, higher productivity, good post harvesting practices; (b) enhanced access – as a result of more stable prices, improved farmer income, or even rural income; and (c) increased stability - through improved and sustained competitive advantage of the member firms, which eventually contribute to sustainable industry including in agriculture. Nonetheless, there has been a limited study linking the concept of food security and the necessity of managing competitive advantage of the agricultural supply chains. This paper links the theoretical foundations of supply chain management the concept of food security policy. Through a review of literature, a concept of how sustainable competitive advantage can be achieved through supply chain management, which in a development context, can improve food security by bringing together the concepts of food availability as well as improved people access to sufficient food is further explored.
