Food security has raised global concerns for generations and is facing new challenges in recent years. With the deep development of globalization, international food trade had made a great contribution to global food security. Based on complex network theory, we used annual staple food (wheat, rice, maize) trade data from to develop the global cereals trade networks. We aimed to study structure and evolution of global cereals trade networks and implications for food security. We show that the global cereals trade networks has growing more complex in the research period. It has been presented core countries and trade communities in the networks.
