Evidence-based solutions for the farmer-cheetah conflict in Namibia
Conflicts between humans, their livestock and carnivores are globally widespread. Developing sustainable solutions is challenging, particularly for threatened carnivore species. We demonstrate with the example of cheetahs in Namibia how detailed information on spatial movements of cheetahs can be used by farmers to adapt their cattle management. This results in substantial decrease of cattle losses and thus in reduced killing of cheetahs by farmers.

Today, there are approximately 7000 free-ranging cheetahs living in Africa with the largest population occurring in Namibia. The majority of this population lives on privately owned farmland and not in protected areas. On farmland, this threatened felid species comes into regular conflict with cattle farmers. Cheetahs sometimes prey on livestock and farmers kill them to protect their cattle.
This project investigates the movement and feeding ecology of cheetahs in the context of human-wildlife conflicts. We detected that cheetahs have a unique socio-spatial organization: some males occupy territories which function as communication hubs and which are used by them, as well as by non-territorial males and females for information transfer. In these communication hubs there is a high local density of cheetahs which results in a high predation risk for livestock.
Based on this discovery, we developed a management scheme in close collaboration with the farmers to identify safe and unsafe areas for breeding herds. This reduced livestock predation by cheetahs substantially, and consequently also decreased the unwanted killing of cheetahs by farmers. Our investigations on diet composition based on faecal analyses and stable isotope analyses of tissue samples revealed that cheetahs are opportunistic hunters that feed mainly on wildlife species and do not specialize on particular prey species.
Additionally, we use camera traps to determine abundances and densities of cheetahs in the various biomes in Namibia to provide a reliable population estimate. An essential component of the project is the involvement of the farmers as important partners into the planning of the subprojects and an open communication of the research results to the farmers. In regular expert panels we also import our research results into politics, for example at the Namibian Ministry of Environment and Tourism, where our results are used for conservation decisions. Additional important partners are the two Namibian universities from which we regularly recruit students.
