On the other side, the term “food security” may assume at least two different meanings. Indeed, it may be referred both to food availability that is dealt with extensively by FAO and to the transposition of “security” issues, as far as known in other contexts, to food production and distribution. The latter meaning suggests the concept of “food defense” that refers to those actions against terrorist or criminal attacks on the supply chain including even ideological actions aimed at causing the supply chain failure.
