Abstract

Reducing postharvest losses (PHL) is key to food and nutrition security in sub-Saharan Africa. However, knowledge of PHL magnitudes is limited. For instance 85% of loss estimates generated using appropriate methodologies did not qualify for statistical meta-analysis because a standard deviation was not assigned to them nor could be computed. Many datasets do not account for the interaction of various loss agents, and are single-point measurements which omit influence of exogenous factors such as local food use patterns, practices, and coping strategies. Overall, technologies for loss mitigation need to address dynamics of supply chains, and more rigorous PHL assessment is needed.
