The current dynamics of urbanization in sub-Saharan Africa pose significant challenges to food and food security for urban populations. In this context, the reflection on the food function of urban and peri-urban agriculture (UPA) is highly relevant and much work has been devoted to analysing the food function of the UAP. On the other hand, little research has been carried out on the essentially commercial dimension of the activity, making it possible to generate income likely to meet the different needs, food and non-food, of agri-urban households. This contribution focuses on this particular aspect of market gardening activity carried out in the Dakar region in three production areas involving 214 market gardeners. The results obtained show that the UPA through urban market gardening in Dakar constitutes a fully-fledged commercial activity whose monetary income is far higher than the minimum wage in Senegal. It turns out that this almost exclusively commercial orientation undoubtedly allows agri-urban households to cover their food and non-food expenses inherent in living in urban areas.
