West African households were particularly affected by the food price crisis of 2007-08. As these households depend on markets for two-thirds of their food supplies, prices have become a key determinant of access to food. However, food prices are 30-40% higher in sub-Saharan Africa than in the rest of the world at comparable levels of per capita income. These price levels have a negative impact on the purchasing power of households and are a major factor of food and nutrition insecurity. Price monitoring systems need to be updated and strengthened. Increasing productivity, promoting regional trade and supporting food value chain development are three of the policy options available to decision-makers to drive down food prices sustainably.
