Tongwe lived in the Mahale Mountains at that time. This area has since been turned into a national park, which does permit settlements.
Kigoma, the regional headquarters and the biggest town in the area, is the main economic center for the peoples of the surrounding area. The railway leading from Dar es Salaam and the Kigoma harbor has
turned the town into a significant economic and political center and the headquarters of many nongovernmental organizations. United Nations organizations working in the region are also located
there. Once a week, a ferry from Kigoma crosses Lake Tanganyika to Bujumbura, Burundi, returns to Kigoma and then cruises south alongside the eastern shore of Lake Tanganyika to Mpulungu, Zambia.
There are two roads leading from Kigoma to the town of Uvinza, from where the road heads southeastward towards Mpanda, the headquarters for Mpanda District of Rukwa Region. One of these
roads to Uvinza passes northward through Kasulu. The other considerably shorter road leads directly from Kigoma to Uvinza. This road was built in order to provide access to one of the refugee camps in the
area. This road was in excellent condition during the survey trip, although it is not marked on most maps. A great mixture of ethnic groups lives along these roads. Uvinza, a ward headquarters in Nguruka
Division, has a large, ethnically mixed population with the Tongwe comprising approximately twenty to thirty percent of the population. Of the four villages comprising the ward of Uvinza, only the village of
Chakulu has a predominantly Tongwe population. The other villages of Nguruka Division are accessible only by train or foot.
The Tongwe live mainly in the Buhingu Division. Those who live along the Malagarasi River can access Kigoma by a small road from Ilagala, which meets the Kigoma-Uvinza road about twenty
kilometers from Kigoma. In the dry season the village of Rukoma is accessible by road from Mpanda through Mwese. All the other villages of this division are accessible only by water. Within Buhingu
Division, the ferry travelling south from Kigoma stops in the villages of Rukoma, Mugambo-Buhingu, Sibwesa shown on some maps as Kibwesa and Kalya. The journey from Kigoma to Kalya takes from
twelve to eighteen hours. Kalya and Kashagulu can also be accessed from the south by ferry or motorboat from the village of Karema, or, as in the case of the survey team, by road to Rukoma and then
by ferry from Rukoma to KalyaKashagulu. The ferry delivers sugarcane, maize, kerosene and fuel for the few motorboats owned by the villagers. It also provides transportation for local vendors travelling
with goods. Apart from the ferry, there are also some cargo boats on the lake. They are reported to be in constant threat of attack by bandits from across the lake.
Some maps of Tanzania show a coastal road from Kigoma that passes south through Ilagala, Sunuka to Rukoma and Buhingu. In reality this road exists only up to Sunuka. In Ilagala there is a ferry which
enables vehicles to cross the Malagarasi River. The stretch of the road from Rukoma to Buhingu also does not exist.
Complex geographical features give rise to the varied vegetation in the Tongwe territory. The Mahale Mountains constitute a high altitude zone with mountains over 2,000 m. Tourist maps such as
those published by Verlag indicate that Nkungwe, the highest mountain, is 2,462 m above sea level. To the east, a plateau that forms part of the eastern side of the Western Rift Valley is mostly inhabited by
the Bende, but also partially by the Tongwe. This plateau varies between 700 m and 2000 m in altitude. Sizeable rivers, including the Malagarasi, Lugufu, Luegele, Lufubu, Lugonesi and Lwega, wind through
the mountains and drain into Lake Tanganyika.
