Guinea has abundant natural resources, including 25% or more of the world's known bauxite reserves. Guinea also has diamonds, gold, and other metals. The country has great potential for hydroelectric power. Currently, bauxite and alumina are the only major exports. Other industries include processing plants for beer, juices, soft drinks and tobacco. Agriculture employs 75% of the nation's labour force. Under French rule, and at the beginning of independence, Guinea was a major exporter of bananas, pineapples, coffee, peanuts, and palm oil. Guinea has considerable potential for growth in the agricultural and fishing sectors. Soil, water, and climatic conditions provide opportunities for large-scale irrigated farming and agro industry.
