Industry
Accounting for 22.6% of GDP, Tanzania's industrial sector is one of the fastest growing in Africa (2010 rankings). Though it has been hit hard recently by persistent power shortages caused by low rainfall in the hydroelectric dams catchment areas, a condition compounded by years of neglect and bad management at the state-controlled electric company. Management of the electric company was contracted to the private sector in 2003. And power production countrywide is currently undergoing various diversification projects. The main industrial activities include agricultural processing (sugar, cigarettes, sisal twine), diamond-, gold-, and iron mining, oil refining, wood products, salt, soda ash, cement, shoes, apparel and fertilizer productions.
