Grenada, the southern most of the Windward Islands, is known as the Spice Island of the Caribbean. It covers an area of 344 km² (133 mi²). The state of Grenada consists of three main islands; Grenada, Carriacou and Petit Martinique. The economy of Grenada is dependent on agriculture and tourism, and while tourism is the main source of foreign exchange, historically, the island has been an agricultural society. Agricultural export products are nutmeg, mace, cocoa, bananas, other fruits, vegetables and fish, while agro-processing is becoming more important. Grenada is the second largest producer of nutmeg in the world and remains a significant producer of mace, cinnamon, ginger and cloves.
