The present study was conducted in Delanta (Ethiopia) to examine the use of medicinal plants and investigate the impacts of the 1984/85 resettlement program on the local people's knowledge on herbal medicine and its uses. The research was conducted with 72 informants in six study sites through semistructured interviews, group discussion, and market survey. In this study, 133 species belonging to 116 genera and 57 families were documented. These plants were mentioned for uses in the treatment of about 76 human and livestock ailments. The family Asteraceae was represented by the highest number with 14 species. Herbs accounted for 52.6% of the total species and leaves (32.6%) were the most frequently used parts. The analysis showed that the resettlement program has both positive and negative impacts on nature rehabilitation and local knowledge along with many human induced threats. Most of the plant knowledge is held by traditional healers and permanent residents. The people's preference for some medicinal plants gave indications of continuity of the ethnomedicinal information among the inhabitants. The findings inform that efforts need to be directed to in situ conservation in two of the plant community types which could protect a good proportion (about 50%) of the medicinal plant species.
本研究在埃塞俄比亚的德兰塔开展,旨在考察药用植物的使用情况,并调查1984/85年重新安置计划对当地居民草药知识及其用途的影响。研究通过半结构化访谈、小组讨论和市场调查,在六个研究地点对72名信息提供者进行。本研究记录了属于57科116属的133种植物。这些植物被提及用于治疗约76种人类和牲畜疾病。菊科植物种类最多,有14种。草本植物占总物种数的52.6%,叶子(32.6%)是最常用的部位。分析表明,重新安置计划对自然恢复和当地知识既有积极影响,也有消极影响,同时还存在许多人为造成的威胁。大多数植物知识掌握在传统治疗师和永久居民手中。人们对某些药用植物的偏好表明民族药用信息在居民中得以延续。研究结果表明,需要对两种植物群落类型进行原地保护,这可以保护相当比例(约50%)的药用植物物种。
