Food for cities in Africa is changing under the triple effect of growth demography, urbanization and transformations in agricultural production and trade. These changes create risks: African cities increasingly face the challenges of undernutrition and malnutrition. But they also generate new opportunities: the economy food is the continent’s main source of employment and will remain so in the near future, both to ensure agricultural production, agro-food processing and product distribution. At the center of this economy are the intermediaries market, which link producers and consumers, and whose ineffectiveness explains that about a third of the production evaporates in food losses.
