About the Cover

The African Civet Civettictis civetta is known for its production of civet musk that is used as fixative in perfume industry. Ethiopia is the world’s main supplier of civet musk. In spite of such a remarkable economic importance, little is known about the current status of the indigenous population and traditional knowledge of African Civet in the wild. Indigenous traditional knowledge and community attitudes towards African Civet were surveyed qualitatively and quantitatively in the eastern sub-catchment of Lake Hawassa Basin, from December 2011 to May 2012. A ‘focus group discussion’ involved 10 discussants were selected by group of researchers from the two target Woreda administration offices of the study area. More formal/quantitative survey targeted 96 rural households in two adjoining Woreda units. Interviewees were selected by stratified direct sampling. Local people apparently are highly familiar with behaviour and economic use of the species. Most people described their relationship with African Civet as neutral (44%) or positive (40%), respectively, and only 16% of 96 interviewees claimed an antagonistic relationship. Most respondents (92% of 66) identified maize as the most damaged crop. More than two-third (71%) of 70 respondents identified guarding, fencing and repellents as a means of minimizing the damage caused by the species, while others indicated that they use lethal trapping (10%), spearing/shooting (7%) and poisoning (3%), respectively. The remaining 9% mentioned that they tolerate civet damage.
