Regionalism and food security is a relatively neglected topic with very limited literature. We use a Ricardian trade model with multiple goods and countries which embeds a structure of gravity equation and yield variability. Our study shows that integration with African markets of staple foods is associated with higher growth, underpinning the need for growth strategies to emphasize scaling up and diversifying exports within Africa. Africa needs to unlock its high potential untapped land and fill up the yield gap. We found as well that enhanced competitiveness and reduced barriers to trade are the two critical areas of action.
