 Abstract: Local and global food security is under pressure. Population growth, people moving up the food chain and a growing use of food for biofuels is increasing the demand for food, while food supply is at the same time challenged by overgrazing, overpumping and climate change. While these trends are threatening international food security, they might also threaten international peace and stability. Referring to the food crisis in 2007-2008 and 2011 and the apparent impact on the rise of several African food riots and the conflicts in Tunisia and Egypt during the Arab Spring, food insecurity has increasingly been presented as a source of civil conflict in the public debate. The thesis at hand wishes to examine this alleged impact of food insecurity on civil conflict.Based on greed and grievance theory, I too expect that food insecurity fuels civil conflict incidence. More specifically, food insecurity is expected to cause discontent and frustration, hence leading to grievance-motivated conflict, just as food insecurity is expected to lower people’s costs of fighting and their profits of looting food, thereby creating greed-motivated conflict. Estimating the impact of food insecurity on civil conflict is however no easy task due to endogeneity and omitted variables bias. In order to address these problems and convincingly establish a causal relationship, I use international food prices as an instrumental variable for food insecurity in 55 African countries in the period 1990-2011, while at the same concluding that precipitation and international oil prices are invalid instruments. The analysis documents, that higher food insecurity is significantly associated with a higher risk of civil conflict incidence in Africa. Thus, the empirical results support the theoretical expectations of greed and grievance theory. The significant relationship between food insecurity and civil conflict incidence remains robust to both OLS and IV-estimation, to the inclusion of several control variables and to changing data sources and variable definitions.
