Agriculture is a major sector of the economy in Equatorial Guinea. Farming accounts for approximately 2% of GDP as it contributes little to the export earnings of the country. In 2022, the Food and Agriculture Organization of the United Nations held its Africa regional conference in Malabo. One popular crop is Tabernanthe iboga which is used for traditional tribal medicine. The island of Bioko has a greater variety of tropical vegetation, including mangroves than the mainland.
