Abstract Postharvest losses (PHL) are a major problem in tomato supply chains, especially in tropical climates, as up to 40% of harvested fruits are estimated to decay along the chain. The study aimed at identifying which farmers' context characteristics, logistics and quality control activities relate with the generation of PHL in tomato supply chains, particularly in Zimbabwe. Commercial and subsistence tomato farmers (n = 197) from five major tomato-growing areas were analysed using a diagnostic tool to assess the status of logistics and quality control activities, the vulnerability of farmers' context, and the actual PHL. Hierarchical cluster analysis resulted in three clusters of farmers grouped based on similarities on context vulnerability and status of logistics and quality control activities. Spearman's rank correlation analysis and multiple linear regression analyses revealed that more advanced logistics and control activities, and context characteristics with a lower vulnerability to PHL are associated with less postharvest losses. The context characteristics, features of storage facilities, features of cropping system, and market price stability were significant determinants (p

确定津巴布韦番茄供应链中收获后损失的决定因素作为专门干预措施的基础

摘要 收获后损失 (PHL) 是番茄供应链中的一个主要问题,尤其是在热带气候中,因为据估计多达 40% 的收获果实沿供应链腐烂。该研究旨在确定哪些农民的环境特征、物流和质量控制活动与番茄供应链中 PHL 的产生有关,尤其是在津巴布韦。使用诊断工具对来自五个主要番茄种植区的商业和自给番茄农民 (n = 197) 进行分析,以评估物流和质量控制活动的状况、农民环境的脆弱性以及实际的 PHL。分层聚类分析导致基于环境脆弱性和物流和质量控制活动状态的相似性分组的三个农民聚类。斯皮尔曼' 秩相关分析和多元线性回归分析表明,更先进的物流和控制活动以及对 PHL 脆弱性较低的环境特征与较少的收获后损失相关。环境特征、仓储设施特征、种植制度特征和市场价格稳定性是重要的决定因素(p
