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.

农户对影响感知牧豆树的入侵：阿法尔民族区域国家，埃塞俄比亚Amibara区的情况下，

在埃塞俄比亚，Prosopis juliflora（P. juliflora）成为最严重的外来入侵物种之一，威胁到牧民和农牧社区的生计，进而威胁其粮食安全。但是，到目前为止，关于该问题的社会方面的研究很少。这项研究探索了家庭对埃塞俄比亚阿法尔民族区域州阿米巴拉地区的朱红假单胞菌入侵影响的看法。该研究使用了根据与家庭规模成正比的概率从130个随机选择的家庭中收集的横截面数据。为了衡量家庭的感知，基于五点李克特量表构建了感知指数，并使用了两个极限的轨道回归模型来确定影响家庭感知的因素。P的丰度 自从将朱丽花引入研究区域以来，人们认为它的数量有所增加，这主要是由于分散剂的流动性以及该物种抵抗恶劣环境的能力。从种植第一批树木到今天，家庭对胡桃木入侵的影响的平均看法发生了重大变化。最初约有78％的抽样家庭支持树木，而如今，只有不到1％的家庭喜欢树木，而约90％的树木则支持。经验证据表明，性别，市场距离，推广服务和生计策略均具有显着的负面影响，而靠近灌木丛土地则对家庭对红花假单胞菌入侵的影响的看法具有明显的积极影响。几乎所有抽样住户都在其自己的土地上采取了某种形式的控制措施，包括拔苗或砍伐树木。我们建议政府机构应与其他利益攸关方合作，设计朱红假单胞菌管理计划，该计划应考虑到住户的利益，人口和社会经济特征以及机构环境。
