Pemba Island is pioneering environmental conservation through traditional spice farming, as reported by the Zanzibar Ministry of Agriculture, Natural Resources, Livestock and Fisheries. This initiative promotes organic farming, which has been effective in increasing tree growth and rainfall. Pemba's farmers grow a variety of spices, including cloves, vanilla, allspice, and peppers, without using chemical fertilizers. The quality of these spices is highly valued on the global market, generating income for the island. The government is regulating the spice trade to prevent undervaluation of crops, and the industry is becoming increasingly popular among local youth and women.
