【 摘 要 】

In Ethiopia, Prosopis juliflora (P. juliflora) becomes one of the worst invasive alien species threatening the livelihood and thus food security of pastoral and agro-pastoral communities. However, up to the present, there have been few studies on the social aspects of the problem. This study explores households’ perceptions about the effects of P. juliflora invasions in Amibara district of Afar National Regional State, Ethiopia. The study used cross-sectional data collected from 130 randomly selected households based on probability proportional to household size. To measure households’ perceptions, a perception index was constructed based on a five-point Likert scale, and a two-limit tobit regression model was used to determine factors affecting households’ perception. The abundance of P. juliflora was perceived to have increased since its introduction in the study area, mainly due to the mobility of dispersal agents and the species’ ability to resist the harsh environment. Between the time when the first trees were planted and today, households’ mean perception about the effect of P. juliflora invasion has experienced a significant shift; whilst initially some 78% of the sampled households were in favour of the tree species, today, less than 1% still favour the tree and some 90% disfavour it. Empirical evidence indicates that gender, market distance, extension service and livelihood strategy had a significant negative influence whilst proximity to the bush land had a significant positive effect on households’ perceptions about the effects of P. juliflora invasion. Almost all sampled households had applied some form of control measure on their individually own land, including uprooting of seedlings or cutting and burning of trees. We recommend that government bodies should, in collaboration with other stakeholders, design P. juliflora management programmes, which take into account the households’ interests, demographic and socio-economic characteristics and institutional settings.
