Economy
Unguja is the island of the Zanzibar Archipelago that has the most developed tourism industry. This accounts for a substantial part of Unguja's economy. Agriculture (including the production of spices such as cloves) and fishing are other relevant activities. All along the east coast, most villages also rely on seaweed farming.[citation needed]
