Руква
The town acts as a supply and commercial center for the Rukwa Region and some governmental agencies are to be found there, notably the transport department for the region. Sumbawanga has both Libori and Moravian conference centres. A modest-size market is in the town centre where local produce may be found. This includes maize, rice, fruit, poultry and fish (from Lake Tanganyika and Lake Rukwa). Many imported plastic goods and electronics are available as well as bicycles and spares. Although there are several fuel outlets, supply can be quite erratic because of the difficulties of transport from the coast.
