Most studies and conceptualizations of tipping points in environmental and climatic systems have been conducted using natural science perspectives and approaches. Socio-scientific contributions - including Anthropology - are scarce. This has resulted in a limited understanding of the socio-cultural dimensions of tipping point phenomena at the local level. This paper contributes to ongoing discussion and provides an ethnographic study of local perceptions of desertification tipping points (DTPs) amongst Ovaherero pastoralists in Namibia’s semi-arid Okakarara constituency. Following a qualitative approach, this study shows that experienced farmers are aware of these phenomena and have accumulated extensive knowledge enabling them to identify and anticipate DTPs in different, complementary ways. The paper discusses how DTPs are managed in a communally farmed setting and presents the challenges that livestock farmers face in practical prevention of DTPs. Keywords: Desertification tipping points, Local knowledge, Pastoralism, Ethnography, Namibia.
