The scientific and politic community has had increasing concerns for strategic understanding and intervention of the food security problem, especially since the 70's food crisis. Different methodological strategies have been used to foresight, to forecast and evaluate policies to support the process of decision-making in the public sector. This paper examines a series of methodologies used to study the food security problem at a national level. Thereafter, we discuss the potential use of complementary methodologies, mainly System Dynamics, as a simulation tool that provides insight on the causal relationships of the critical variables and allows the analysis of different scenarios of intervention in favor of effective decision making
