Food Systems and the Escape from Poverty and Ill-Health Traps in Sub-Saharan Africa

Millennium Development Goal #1 is to halve extreme poverty ($1/day per person) and hunger. Progress toward this goal has been excellent at global level, led by China and India, but woefully insufficient in sub-Saharan Africa. In Africa, a disproportionate share of the extreme poor are ultra-poor, surviving on less than $0.50/day per person, a condition that appears both stubbornly persistent and closely associated with widespread severe malnutrition - "ultra hung" - and ill health. Indeed, ill health, malnutrition and ultra-poverty are mutually reinforcing states that add to the challenge of addressing any one of them on its own and make integrated strategies essential. Food systems are a natural locus for such a strategy because agriculture is the primary employment sector for the ultra-poor and because food consumes a very large share of the expenditures of the ultra-poor. The causal mechanisms underpinning the poverty trap in which ultra-poor, unhealthy and undernourished rural Africans too often find themselves remain only partially understood, but is clearly rooted in the food system that guides their production, exchange, consumption and investment behaviors. Four key principles to guide interventions in improving food systems emerge clearly. But there remains only limited empirical evidence to guide detailed design and implementation of strategies to develop African food systems so as to break the lock of poverty and ill-health traps
