To review and synthesize studies on household food security in South Africa.
Systematic mapping review of metrics (methodological review).
Electronic databases, including EBSCOHost, Scopus and Web of Science, were searched for studies and reports on household food security in South Africa, reporting household food security published between 1999 and 2021. Searching, selecting and reporting were performed according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement.
South African households.
Forty-eight articles reporting on six national surveys (one repeated annually since 2002) and forty sub-national studies meeting the inclusion criteria were selected. Various metrics, with different recall periods and ways of categorizing food security levels, were identified. Surveys that used similar metrics showed that the percentage of South African households that have experienced food insecurity and hunger has decreased over the review period yet remains concerning. However, the multitude of metrics used to assess the different components and levels of food security limits the comparability of the results to evaluate the scope and scale of the problem.
There is growing support for developing multi-variable approaches for food security research in sub-Saharan Africa. Future research should focus on finding the most appropriate combination of complementary metrics that would allow comparable data while holistically capturing food security and providing insight into the causes and consequences.
综述和综合南非家庭粮食安全研究。
对度量标准(方法学综述)进行系统制图综述。
电子数据库,包括 EBSCOHost、Scopus 和 Web of Science,用于搜索和报告南非家庭粮食安全的研究和报告,报告的家庭粮食安全发表于 1999 年至 2021 年期间。根据 PRISMA(系统评价和荟萃分析的首选报告项目)声明进行搜索、选择和报告。
南非家庭。
选择了 48 篇报告了六个全国性调查(自 2002 年以来每年重复一次)和四十项符合纳入标准的次国家研究的文章。确定了各种具有不同回忆期和分类粮食安全水平的指标。使用类似指标的调查表明,在审查期间,经历粮食不安全和饥饿的南非家庭比例有所下降,但仍令人关切。然而,用于评估粮食安全不同组成部分和水平的众多指标限制了结果的可比性,难以评估问题的范围和规模。
越来越多的人支持在撒哈拉以南非洲开展多变量粮食安全研究方法。未来的研究应重点寻找最合适的互补指标组合,允许进行可比数据的同时全面捕捉粮食安全,并深入了解其原因和后果。
