In a context of increasing concern regarding food loss and waste (FLW) generation, different attempts have been made to standardize quantification methodologies. On the one hand, an important number of small-scale studies have been published that constitute direct measurement methodologies. On the other hand, the FAO Food Balance Sheets, which aggregate some of the prior studies, provides an indirect metric that has been applied using FLW coefficients in numerous food-related studies. However, to date, no standard methodology has been agreed upon to quantify FLW. This study performs an assessment of 237 studies in the field, aiming to identify existing FLW quantification methodologies, and if there is a need of developing alternative paths. Firstly, a descriptive review was performed. Secondly, an assessment of critical point of views was presented. For this, different critical voices in the scientific literature were retrieved, some of which highlight the high level of uncertainty and a certain degree of opacity in some of the most widespread FLW quantification and assessment reports. In this line, essential elements of quantification are being omitted. Moreover, the focus is being excessively placed on the role of the consumer, compared to the role played by agribusiness and large distribution chains.

对粮食损失和浪费量化方法的批判性审查:是否需要在目前广泛使用的途径之外开发替代方案?

在对粮食损失和浪费 (FLW) 产生的日益关注的背景下,已经进行了不同的尝试来标准化量化方法。一方面,已经发表了大量构成直接测量方法的小规模研究。另一方面,汇总了一些先前研究的粮农组织食品平衡表提供了一个间接衡量标准,该衡量标准已在众多食品相关研究中使用 FLW 系数应用。然而,迄今为止,尚未商定量化 FLW 的标准方法。本研究对该领域的 237 项研究进行了评估,旨在确定现有的 FLW 量化方法,以及是否需要开发替代路径。首先,进行了描述性审查。第二,提出了对关键观点的评估。为此,检索了科学文献中的不同批评声音,其中一些突出了一些最广泛的 FLW 量化和评估报告中的高度不确定性和一定程度的不透明性。在这一行中,量化的基本要素被省略了。此外,与农业综合企业和大型分销链所扮演的角色相比,人们过度关注消费者的角色。
