This paper explores the role of African worldviews in biodiversity conservation and sustainable development. African worldviews recognise the interdependence and interconnectedness of human beings, animals, plants and the natural world. Although it is not always the case that what one does depends on what one thinks and believes, indigenous African people's ideas and beliefs about the human–nature relationship have influenced what they have done in and to nature. In African worldviews, the present generation has moral obligations to the ancestors and (...) future generations. It ought to preserve the environment, which is rich in biodiversity, for posterity. This paper insists that it is extremely urgent that every effort be made to document the knowledge of peasant farmers and indigenous people in general. This paper further stresses that indigenous environmental knowledge makes a big difference to sustaining diverse environments, and it is imperative to preserve such knowledge before it dies out.
