This paper presents the state of world food security and the impact on the security of the processes of agribusiness sector globalization. It was stated that the processes of globalization occurring in agriculture and the food economy have various multidirectional impact on the global food security. On the one hand they contribute to the growth of global production which can result in greater access to food. On the other hand, these processes can cause deterioration of food security, mainly due to the move away from sustainable to large-farming, industrialized agriculture, in which large agricultural corporations take over more value-added links and leads to oligopolization of global agribusiness space. This causes a loss of profits by the current owners and the deterioration of their affordability. Lowest affordable price of food and thus the worst food security is located in sub-Saharan Africa.
