The Twa of the Lukanga Swamp of Zambia are one of several fishing and hunter-gatherer castes living in a patron–client relationship with farming Bantu peoples across central and southern Africa.
In Southern Province, where swampy terrain means that large-scale crops cannot be planted near the main rivers, only the Twa fish.
Up to the 1920s the Twa built their huts on the marshes, but they were moved to higher ground for ease of taxation.
They have been replaced by immigrants to the region, primarily Luvale and Malawians.
