Kansyore pottery-using groups of the northeastern Lake Victoria Basin represent one of only a few examples of ‘complex’ hunter-gatherers in Africa. Archaeologists link evidence of specialized fishing, a seasonal land-use cycle between lake and riverine sites, and intensive investment in ceramic production to behavioral complexity after 9 thousand years ago (ka). However, a gap in the Kansyore radiocarbon record of the region between ~7 and 4.4 cal ka limits explanations of when and why social and economic changes occurred. This study provides the first evidence of lakeshore occupation during this temporal break at the only well-studied Kansyore site in eastern Uganda, Namundiri A. Within the context of other sites in nearby western Kenya, radiometric and faunal data from the site indicate a move from the lake to a greater reliance on riverine habitats with middle Holocene aridity ~5–4 cal ka and the arrival of food producers to the region after ~3 cal ka.

维多利亚湖盆地东北部的 Kansyore 陶器使用群体代表了非洲“复杂”狩猎采集者的少数几个例子之一。考古学家将专业捕鱼的证据、湖泊和河流遗址之间的季节性土地利用循环以及陶瓷生产的密集投资与 9 千年前 (ka) 后的行为复杂性联系起来。然而，该地区 Kansyore 放射性碳记录在 ~7 和 4.4 cal ka 之间的差距限制了对社会和经济变化发生的时间和原因的解释。这项研究提供了乌干达东部唯一被充分研究的 Kansyore 遗址 Namundiri A 在此时间间隔期间湖岸被占领的第一个证据。在肯尼亚西部附近其他遗址的背景下，
