This article explores how traditional ecological knowledge in Cerekang, South Sulawesi, Indonesia, is culturally transmitted as a strategy for cultural survival amidst internal and external challenges such as social, ecological, and political changes. Traditional ecological knowledge of the Cerekang people lies from mythological construction of the La Galigo epic, which contain beliefs, collection of instructions, and rules on conservation and preservation of sacred forest and non-sacred forest. This knowledge are culturally transmitted through oral stories, rituals, daily life, and customary organization. Generally, the transmission takes place vertically, horizontally, and obliquely. The traditional, linear-vertical mode of transmission, which tends to be closed, is the most dominant pattern of cultural transmission among the Cerekang people. This study also finds out another pattern of transmission beyond the framework given, which we call as conformist transformation. However, this cultural transmission is not without bias as the transmitted messages are generic and incomplete. Therefore, a contextual education in both formal and informal settings as another mode of cultural transmission is suggested to respond to current social, political, and environmental changes in Cerekang. In order to sustain the Cerekang’s TEK, the local government policy-maker should further facilitate indigenous activities by supporting capacity building in non-formal setting and signing a decree to include TEK in formal education.
