ABSTRACT

Even though the Gamo zone is a prevalent mango producing area in Ethiopia, the lack of comprehensive post-harvest loss research along the mango value chain prevents respective stakeholders from recognizing the socioeconomic, nutritional and environmental significance of the post-harvest loss problem. Improving the post-harvesting handling practice not only increases the production by reduction of post-harvest loss but also increases food access at the market level with prices adjustment. Therefore, this study was intended to assess the post-harvest loss along the mango value chain and the challenges that actors and stakeholders face in the process. To do this, 120 mango producers were selected following a multistage sampling procedure. The analysis result shows that the main reasons for the low productivity of mango are the use of the local variety, disease and insect pests and lack of improved harvesting technologies. The result also shows about 41% of mango loss in the study area was due to a lack of improved harvesting mechanism and infection by disease and pests and poor transportation mechanisms. From this loss, the harvesting stage shares the largest share (18%) along the mango value chain. In addition, lack of improved mango varieties, lack of cooperative and wholesale marketing and lack of value addition practice are the major identified problems in the study area. There is also a huge loss of mango production in the study area that needs immediate intervention from respective stakeholders. Thus, dissemination of improved varieties through the distribution of seedlings, modifying the existing harvesting materials and introduction of improved harvesting technologies, strengthening the cooperative marketing and supporting alternative products development through processing was suggested.

摘要

尽管加莫区是埃塞俄比亚的芒果产区，但缺乏对芒果价值链上的全面采后损失研究，使相关利益相关者无法认识到采后损失问题的社会经济、营养和环境意义。改进收获后处理方法不仅通过减少收获后损失来增加产量，而且通过价格调整增加了市场层面的粮食供应。因此，本研究旨在评估芒果价值链中的收获后损失以及参与者和利益相关者在此过程中面临的挑战。为此，经过多阶段抽样程序选择了 120 家芒果生产商。分析结果表明，芒果产量低的主要原因是使用当地品种、病虫害和缺乏改良的收获技术。结果还表明，研究区约 41% 的芒果损失是由于缺乏改进的收获机制以及病虫害感染和运输机制不佳造成的。从这一损失来看，收获阶段在芒果价值链中所占份额最大（18%）。此外，缺乏改良芒果品种、缺乏合作和批发营销以及缺乏增值实践是研究领域发现的主要问题。研究区域的芒果产量也存在巨大损失，需要相关利益相关者立即干预。因此，通过分发幼苗传播改良品种，
