Abstract

The issue of food loss and waste is a complex one that must be addressed if sustainable food systems are to be achieved. In the Global South, as evidenced by Nigeria, two paradoxical trends can be observed. Firstly, substantial losses of arable crops occur during the production and distribution stages. Secondly, Nigeria is affected by food scarcity, which is in part a consequence of losses occurring at these stages. In terms of food availability, Nigeria ranks 26th among African countries. In light of this context and the government's expressed interest in identifying sustainable solutions to this problem, a systematic review was conducted with the objective of consolidating the fragmented studies on food loss in the region. This review provides a foundation for understanding the causes of food loss, the preventive and reduction strategies required, and for identifying promising areas for future research. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Checklist 2020. Following the application of inclusion and exclusion criteria, 23 studies were selected for review. A thematic synthesis was employed to integrate and examine the findings of the studies. The findings indicated that maize, rice, and cassava continued to be the most prevalent food crops in Nigeria, with cultivation occurring across the entire country. We differentiate the critical loss points for different crops, which arise between the production and distribution stages. In conclusion, this review reveals that food loss in Nigeria is a multifaceted issue requiring integrated solutions that address the natural, social, and material dimensions. Further empirical research, especially qualitative studies that focus on the perspectives and practices of food system actors, is essential for developing effective interventions and policies. This approach will help achieve sustainable development of food systems and advance global food security goals.

尼日利亚的食物损耗分析:系统文献综述
粮食损失和浪费是一个复杂的问题,必须加以解决,才能实现可持续的粮食系统。在全球南部,正如尼日利亚所证明的那样,可以观察到两个矛盾的趋势。首先,耕地作物在生产和销售阶段出现大量损失。其次,尼日利亚受到粮食匮乏的影响,这在一定程度上是这些阶段损失的结果。在粮食供应方面,尼日利亚在非洲国家中排名第 26 位。鉴于这种情况,以及政府表示有兴趣找到解决这一问题的可持续办法,我们进行了一次系统性回顾,目的是整合该地区有关粮食损失的零散研究。该综述为了解食物损耗的原因、所需的预防和减少战略以及确定未来有希望的研究领域奠定了基础。综述按照《2020 年系统综述和元分析首选报告项目(PRISMA)清单》进行。根据纳入和排除标准,共选出 23 项研究进行综述。采用专题综合法对研究结果进行了整合和审查。研究结果表明,玉米、水稻和木薯仍然是尼日利亚最普遍的粮食作物,种植范围遍及全国。我们区分了不同作物在生产和销售阶段的关键损失点。总之,本综述揭示了尼日利亚的粮食损失是一个多方面的问题,需要针对自然、社会和物质层面的综合解决方案。进一步的实证研究,特别是侧重于粮食系统参与者的观点和做法的定性研究,对于制定有效的干预措施和政策至关重要。这种方法将有助于实现粮食系统的可持续发展,推进全球粮食安全目标。
