Published by the Economic Research Service of the US Department of Agriculture, this study examines the two main food gaps, the status quo gap and the nutritional gap, to measure food insecurity in order to study the ways in which these two food gaps are affecting different regions of the world population. The report found Sub-Saharan Africa to be the most vulnerable in respect to food security, mainly due to population growth, and Northern Africa was the only region studied that has been able to meet the nutritional needs of its population.
