由于人口迅速增长和粮食价格波动，撒哈拉以南非洲对粮食不安全的担忧日益加剧。减少收获后损失已被确定为补充应对粮食安全挑战和提高农业收入，特别是农村贫困人口的努力的一个关键组成部分。本研究分析了建议的收获后处理方法在减少PHL中的作用，并对采用与降低损失相关的方法进行了成本效益分析。研究发现，玉米农民在收获后系统中损失了约11.7%的收成。大约三分之二的损失发生在储存过程中。研究表明，采用建议的收获后处理方法与较低的PHL高度相关。最后，研究发现，实施一些建议的做法的成本超过了与较低的PHL相关的好处。然后，它讨论了为什么有些农民可能不采用的一些做法的原因，并指出了一些文献的贡献。
Concerns about food insecurity have grown in Sub-Saharan Africa due to rapidly growing population and food price volatility. Post-harvest Losses (PHL) reduction has been identified as a key component to complement efforts to address food security challenges and improve farm incomes, especially for the rural poor. This study analyses the role of recommended post-harvest handling practices in PHL reduction; and conducts a cost-benefit analysis of adopting practices associated with lower losses. The study finds that maize farmers lose about 11.7 percent of their harvest in the post-harvest system. About two-thirds of this loss occurs during storage. The study shows that adoption of recommended post-harvest handling practices is highly correlated with lower PHL. Lastly the study finds that the cost of implementing some of the recommended practices outweighs the benefits associated with lower PHL. It then discusses the reasons why some farmers may not adopt some of the practices and points out some contributions to the literature.
