Knowledge Loss and Change Between 2002 and 2017a Revisit of Plant Use of the Maasai of Sekenani Valley, Maasai Mara, Kenya

Traditional plant use is of tremendous importance in many societies, including most rural African communities. A variety of studies have shown knowledge dwindling due to changes towards a more Western lifestyle, and the influence of modern tourism. In the case of the Sekenani Maasai, we hypothesized in 2006 that, while little knowledge loss had been observed at that time, the change from a nomadic to a more sedentary lifestyle would lead to an accelerating loss of traditional plant knowledge. This paper examines the plant use of the Maasai in the Sekenani Valley, North of the Maasai Mara National Reserve 15years after a first study. Based on the study of 2002 (Bussmann et al. Journal of Ethnobiology and Ethnomedicine 2: 22, 2006), semi-structured interviews were conducted with staff of Sekenani Camp in order to document current plant knowledge. The results of this follow-up study indicate dramatic knowledge loss over the last 15years. Of 139 used species documented in 2002, only 84 remained in use in 2017. Off those species still in use, 30 had experienced a loss of uses, while for 18 species new uses were documented. The knowledge loss observed in Sekenani in 15years is rather dramatic. Lifestyle changes and over-use of resources have clearly led to a rapid decline of traditional knowledge on plant use. This trend is expected to continue.
