Rice, millet, sorghum, and maize are the primary staple foods in Senegal.
Groundnuts are both an important source of protein and a commonly grown cash crop. Imported rice is consumed daily by the vast majority of households in Senegal particularly in Dakar and Touba urban centers. Local rice is produced and consumed in the Senegal River Valley. St. Louis is a major market for the Senegal River Valley. Millet is consumed in central regions where Kaolack is the most important regional market. Maize is produced and consumed in areas around Kaolack, Tambacounda, and the Senegal River Valley. Some maize is also imported mainly from the international market. High demand for all commodities exists in and around Touba and Dakar. They are also important centers for stocking and storage during the lean season. The harvests of grains and groundnuts begin at the end of the marketing year in October; and stocks of locally produced grains are drawn down throughout the marketing year. Senegal depends more on imports from the international market for rice than from cross border trade which mainly includes cattle from Mali and Mauritania that supply Dakar and surrounding markets.
