[8] In descriptions from the early 20th century Bangweulu Twa are said to live off the land, they had no domestic animals but cultivated around ant-hills and on other raised patches.
Through trade with inland neighbours they got meal and grain.
[4][9] Eric von Rosen visited the Twa during his expedition in Bangweulu during 1911 and 1912 and calls them the "Swamp people".
[10][9] Von Rosen collected ethnographica and took photographs which are today in Sweden at the Museum of Ethnography in Stockholm and the Museum of World Culture in Gothenburg.
After von Rosens expedition the Lake dwellers have been steadily moving to the main land.
