Many long-term monitoring programs related to food security conducted by dedicated UN organizations, such as FAO or WFP, or else the World Bank, demonstrate the relevance of the issue on adequacy between population growth and agricultural production growth.The issue is even more crucial for Sub-Saharan Africa, where projections for future years globally predict that, at the current rate of the admittedly positive change in food availability, this one will nevertheless be able to satisfy the growing needs of the populations only if it is accompanied by political and institutional actions, adjustments and efforts in various essential fields, agricultural as well as non-agricultural [FAO 2016; FAO, 2017].A finding has quickly emerged that this adequacy is neither trivial nor linear and that it is a necessary but not sufficient condition for reducing food insecurity. The links between agricultural production growth and nutrition are “extremely complex and not immediate” [Dury et Bocoum, 2012], and reveal a wide range of possible situations, from the most expected to the most paradoxical.It is then proposed to systematize the identification of the different possible forms of combinations of the three evolutionary trajectories of population, food situation and available resources, using relevant indicators, to have a refined view of these forms, characterize them and measure their acuity. One can then identify the levers and brakes to food security/securing in urbanization, market, land policy or development contexts, in order to help to efficiently target the accompanying measures and intervention policies, and evaluate their priority.
