Dynamique des savoirs naturalistes des Pygmées Batwa de la région du Lac Tumba face au changement de leur mode de subsistance [ Dynamic in traditional knowledge and know-how in Batwa communities of Tumba Lac landscape, Democratic Republic of Congo, due to livelihood changes ]

This study reports on changes in traditional knowledge and know-how in Batwa communities due to livelihood changes especially due to cassava cultivation ownership. We compare Batwa (pygmies) and Ntomba (bantou) communities living in the two villages (Iyanda and Sekri) in Congolese jungle. Results revealed that Batwa communities have lost significant knowledge packages after they adopted bantou livelihood behavior. This situation should be well managed to avoid the complete loss of Batwa traditional knowledges and know-how.
