Indigenous pastoralists are hardest hit by the impacts of climate change because of their dependence on nature and limited adaptation. This paper seeks to examine the level of integration of traditional knowledge systems into adaptation policies in Cameroon, using the specific case of Mbororo pastoralists in the Western Highlands. Using a mainly qualitative approach in data collection, in-depth interviews were conducted with 28 purposively selected pastoralists from 4 divisions with intense pastoral activity, comprising 19 Mbororo pastoralists, 2 members of the Mbororo Social and Cultural Association (MBOSCUDA), 2 Mbororo traditional rulers, 5 Mbororo women and one focus group discussion. Discussions were recorded and voice notes were transcribed, coded and treated according to content and thematic with the aid of Atlas. Ti software. Results show that Mbororo pastoralists migrated into the region in the 1950s as nomadic herders and occupied marginal lands due to the nature of their activity. With climatic aberrations being acute, their closeness to nature permitted them to develop a wide array of knowledge and traditional practices to adapt and exploit existing opportunities. Semi-nomadic and transhumance methods of rearing, cross-breeding local species with high-breed species to produce resistant breeds of cattle, cultivating resistant pasture species, rotational grazing and using traditional medicines to treat cattle diseases have reduced resource degradation and curbed the effects of climatic aberrations. Nevertheless, these indigenous knowledge systems are eroding fast due to poor indigenous institutions and non-integration into policy. This work will reinforce capacities of decentralized communities in developing and implementing local adaptation plans on climate change.
