and the population today constitutes also the descendants of Lipangalala, Ndwangira and Mfalikuivahaa, who as leaders from Zululand and Southern Africa arriving in Ifakara and the region as of the late 1860s (Larson 1976:14). Other ethnic groups include Hehe, Sukuma, Bena, Gogo, Ruguru, Kyurya, Pare, and Chagga. In terms of religion, Christians outnumber Moslems and pagans because of early settlements of missionaries in the area. A year after the British mandate was pronounced by the League of Nations in 1920s, the Capuchin Mission started work in Ifakara. The Swiss missionary work emerged in a context of acute social and political change. The missionary range of services offered was not only spiritual and pedagogical, but also medical. Christian missions had a reputation as conveyors of European medical science. Sr. Arnolda Kury, from the Franciscan Baldegg congregation of the “Schwestern von der Göttlichen Vorsehung" built a small dispensary in 1927. This facility developed over the years and grew considerably when the St. Annaheim maternity hospital was added in 1944. In 1953, Dr. Karl Schöpf designed and built a modern and new hospital, now called St. Francis Hospital, with support from Sr. Arnolda, the powerful parish priest and not least the Capuchin Bishop of the Archdiocese of Dar es Salaam. Today the mission hospitals have become 'health projects' executing 'health programmes' which are sold on the secular and spiritual, as well as private and public, market created by donors in Switzerland and elsewhere. Economy Fishing has always been the main economic activity of the people living along the Kilombero River. The river provides different fish species including prawns, sardines, ndipi, mbewe, kitoga, tilapia, mjongwa, catfish, sulusulu, bulu, juju, ngunga, ngufu, ngundu, nguyu, ningu and mbala. The Ndamba are distinguished from the Pogoro of Mahenge highlands and its lowland peripheries by their riverine economy and technology. The technological superiority of the Ndamba lies in their control of canoe transport and grasp of riverine lore, which enables them to slip into vast and complicated waterways and survive there for lengthy periods. For a long time, Larson (1976) notes, the Ndamba gained access to the fertile alluvial fans only during the dry season. Other subsistence activities include hunting and cultivation. Today, people also farm. While rice is the main food stuff, sugarcane, maize, millet and wheat are essentially grown for food and trade. Environment and geography Ifakara largely occupies the central position on the fertile alluvial
