[English] The paper observed that the various ethics that constitute the system of African environmental ethics are not based on or linked to any known African ontology and formal logic. It argued that the contextualisation of African environmental ethics on African ontology and African logic is essential since Western ontology and logic do not serve to adequately explain and provide proper meanings to the various concepts and propositions employed in the African environmental ethics. Therefore, the paper aimed to, and indeed, (...) link and establishes African environmental ethics on a definite and sound African ontology and formal logic based on Ibuanyidanda complementary ontology and Ezumezu integrativist logic. -/- [Annang] Nwed ndun̄ọ ami akondo ada akud ate k’ idem mme ido ukpeme nkan-n̄kuk ke Africa ada nsan nsan ye ọntọlọgy ye lọgik Africa.
