Purpose – The purpose of this paper is to use cross-country data to investigate whether convergence process exists in per capital nutrient supply and also identify the determinants of change in per capita nutrient supply in sub-Saharan Africa (SSA). Design/methodology/approach – Annual time series data for 43 countries covering 1975-2009 that yields balanced panel were employed for the analysis. The convergence hypothesis is examined based on the neoclassical growth model using feasible generalized least square approach that is robust to autocorrelation and cross-sectional dependence. Findings – The empirical results lend support to existence of convergence process in nutrient supply in SSA. Evidence of convergence in nutrient supply may have contributed to observed reduction in incidence of food-poverty in the region, which aligns with the argument in literature that recent Africa food security gains are due to food imports. The results of the determinants of change in nutrient supply showed that, global food trade represented by trade openness consistently increased growth in nutrient supply across countries in SSA significantly. Meanwhile, the speed of convergence of per capita nutrient supply, which measures how quickly growth in nutrient supply increases over time is very low, as this calls for urgent policy attention in the region. Originality/value – The very first study to investigate convergence in food consumption and nutritional supply in SSA.
