Unpacking Postharvest Losses in Sub-Saharan Africa: A Meta-Analysis
通过元分析揭示撒哈拉以南非洲采后损失的性质、规模及干预措施，发现评估方法不足且损失多为经济性，现有技术未能解决供应链动态问题。
Reducing postharvest losses (PHL) is a key pathway to food and nutrition security in sub-Saharan Africa. However, knowledge of PHL magnitudes is limited. A meta-analysis has been conducted to expose nature and magnitude of PHL, and the kinds of interventions that have been attempted to mitigate the losses. Findings reveal inadequacies of loss assessment methodologies that result in inaccurate PHL estimates. Moreover, losses are often economic rather than physical product losses. Overall, technologies for loss mitigation fail to address dynamics of supply chains. Consequently, rigorous PHL assessment using systematic methodologies, as well as holistic approaches for losses mitigation are in need.
