Food Security

In Mozambique’s Gaza and Sofala provinces between 2002 and 2003, a controlled feeding trial distributed orange-fleshed sweet potato (OFSP) varieties to households whose diets had long been dominated by white-fleshed cultivars providing negligible provitamin A. After six months, children aged six to thirty-five months in the OFSP intervention group showed a 30 per cent reduction in the prevalence of vitamin A deficiency compared with controls, and their mean serum retinol concentrations rose significantly despite no change in supplement delivery or health-system inputs. Mothers who consumed the orange-fleshed variety also demonstrated improved vitamin A status, suggesting that a single dietary substitution - one crop variety replacing another - could reach two nutritionally vulnerable groups through an ordinary agricultural pathway rather than through clinics or distribution chains (Low et al., 2007) . That result, now more than two decades old, remains one of the clearest demonstrations that breeding can do nutritional work that supplementation programmes frequently fail to sustain.

According to the most detailed global estimate available, approximately 281 million people across Sub-Saharan Africa (SSA) were undernourished in 2019 - nearly 22 per cent of the region’s total population and roughly half of all people experiencing chronic undernourishment worldwide.¹ That figure, published in the 2020 edition of The State of Food Security and Nutrition in the World, summarises decades of compounding structural failures: poverty, conflict, climate instability, gender subordination, and chronically under-resourced rural infrastructure.

In 2011, Somalia experienced what the United Nations formally declared a famine - the first such declaration anywhere in the world since the 1980s. An estimated 260,000 people died, more than half of them children under five. Yet the famine did not arrive unannounced. Early warning systems had been sounding alerts for months, satellite data had documented consecutive failed harvests across southern Somalia, and price indices in Mogadishu’s Bakara market had flagged catastrophic food-access deterioration well before acute mortality accelerated. What failed was not measurement but its conversion into political action - constrained by armed conflict, donor fatigue, and the systematic underfunding of response logistics. The Somali famine is an instructive starting point for any serious discussion of food security not because it represents the concept at its most legible, but because it reveals its most dangerous fault lines: the gap between knowing a population is food insecure and possessing the institutional architecture to correct it.

In 2007–2008, global cereal prices rose by more than 80 per cent within eighteen months, triggering food riots across at least 30 countries - from Haiti to Cameroon to Bangladesh.¹ Yet in the European Union, household food expenditure as a share of income barely shifted, buffered by the Common Agricultural Policy’s (CAP) price stabilisation mechanisms and strategic grain reserves. The same price shock that destabilised governments across Sub-Saharan Africa registered, in Brussels, as a supply-chain footnote. That asymmetry is not incidental. It is the structural outcome of decades of divergent institutional investment, measurement philosophy, and policy architecture - and it is what makes direct metric comparison between these two regions so analytically treacherous.
