The traditional economy is limited to the raising of goats, camels, and sheep, and the cultivation of date palms. There is coastal fishing. Large deposits of phosphates at Boukra (near Laayoune) were first exploited by a Spanish-controlled firm in the early 1970s; Morocco has since taken primary control of the firm. Potash and iron deposits exist at Agracha. There is a growing tourist industry. The region has a limited transportation network; the main seaports are Dakhla and Laayoune. Phosphates and dried fish are exported, while fuel and foodstuffs are the main imports.
