This chapter deals with hunger and livelihood insecurity in the face of corporate globalisation. It argues that hunger and livelihood insecurity are a manifestation ofstructural causes that determine access to and control over means of production and participation in decision-making processes. It specifically argues that hunger is an even more complex phenomenon, determined not only by the availability,access and affordability of food, but by the meaningful participation of producers in production, value chain and decision-making processes, and influenced by the socio-political context and global economic forces. The concentration of resources,knowledge and power in the hands of multinational corporations as part ofcorporate globalisation is posing new challenges in the fight against hunger and livelihood insecurity, as well as threatening national food sovereignty. In addition,climate change and the promotion of bio-fuels worldwide have implications for food availability and an inherent relationship with trade and food prices, also affecting hunger, livelihood security and national food sovereignty. These issues have the potential to impact on the effective implementation of the Millennium Development Goals
