Food security implications of staple food substitution in Sahelian West Africa

Abstract: Low-income households in Sahelian West Africa face multiple shocks that risk compressing their already-low food consumption levels. This paper develops a multi-market simulation model to evaluate the impact of common production and world-price shocks on food consumption of vulnerable groups in Sahelian West Africa. Empirical analysis confirms that poor households bear the brunt of ensuing consumption risks, particularly in closed markets, where trade barriers restrict imports, and the poor find themselves in a bidding war with richer consumers for limited food supplies. In the absence of trade, a drought that reduces domestic rainfed cereal production by 20% would compress already low calorie consumption of the rural poor by as much as 15%, four times as much as other household groups. Conversely, a 50% spike in world rice prices hits the urban poor hardest, compressing calorie consumption by up to 8%.
