Abstract

Food security which is defined 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’ has become one of this century’s key global challenges. In 2007 and 2008, increased food insecurity due to the dramatic rise in food prices led to a global crisis, causing political and economic instability and social unrest in many countries.
