Sahel is a drought-prone area in West Africa, and the agriculture sector remains the main source of employment in the rural communities. However, inter-annual rainfall variability significantly hampers the performance of agriculture in Sahel. Over the past four decades, drought episodes have been the norm rather than the exception in the region. Using a just-Pope stochastic production function, this paper assesses crop yields responses to persistent drought spells in eight countries of Sahel.
