Violent conflicts claim 3,000 lives per day through wars, bombings and attacks that dominate the news media. Meanwhile, behind the headlines, 20,000 people die each day from causes related to hunger and poverty. Physical security and food security are deeply connected. Over a billion people suffer from chronic food insecurity, a situation that feeds violent conflict and weakens national and international security. Food insecurity is especially problematic in agricultural regions where income growth is constrained by resource scarcity, disease, and environmental stress. This research theme seeks to unravel the "deadly connections" among hunger, disease, environmental degradation, climate change and civil conflict in poor countries.
