Purpose

The purpose of this paper is to systematically review and critically examine food losses and waste quantification in supply chain, especially in studies that tackle all the supply chain activities in a real context.

Design/methodology/approach

This work employed a systematic literature review methodology on the extant literature focusing on peer-reviewed journal articles published from 2000 to 2019.

Findings

A systematic analysis of 117 articles reveals that downstream supply chains are studied to a greater extent than upstream supply chains, with an emphasis on consumer waste. The findings also highlight more than half of the articles focus on only one supply chain activity. In terms of the methodologies, surveys and modelling methods are the most used to measure food losses and wastes, adopt monetary, carbon emission and calorific metrics. This study highlights that while food losses and waste research remains a relevant field of study, it has yet to been fully explored.

Research limitations/implications

The main limit is the adoption of a systematic review method for food losses and waste quantification in supply chain.

Practical implications

The results suggest that supply chain managers should invest in acquiring more knowledge about food losses in the global network. Upstream supply chains should be more studied and integrated with the downstream supply chains. Using combined direct and indirect methods has the potential to deal with the contradictions of quantification, the lack of data and reduce losses over time and space.

Originality/value

1. We analyse 117 studies addressing food losses and waste quantification.

2. Downstream food supply chains are more studied than upstream food supply chains.

3. Case studies of food supply chains in developed countries are more prolific.

4. The main metric to quantify food losses and waste is weight.

供应链中的粮食损失和废物量化：系统的文献综述

目的

本文的目的是系统地审查和批判性地检查供应链中的粮食损失和废物量化，特别是在解决实际情况下所有供应链活动的研究中。

设计/方法/方法

这项工作对现有文献采用了系统的文献综述方法，侧重于2000年至2019年发表的经过同行评审的期刊文章。

发现

对117篇文章的系统分析表明，与上游供应链相比，对下游供应链的研究程度更高，重点是浪费消费者。调查结果还强调，超过一半的文章只关注一个供应链活动。就方法论而言，调查和建模方法最常用于衡量粮食损失和浪费，采用货币，碳排放和热量指标。这项研究强调，尽管粮食损失和浪费的研究仍是一个相关的研究领域，但尚未进行充分的探索。

研究局限/意义

主要限制是对供应链中的粮食损失和废物量化采用系统的审查方法。

实际影响

结果表明，供应链管理者应进行投资，以获取更多有关全球网络中粮食损失的知识。应进一步研究上游供应链，并将其与下游供应链整合。结合使用直接和间接方法有可能解决量化的矛盾，数据的缺乏并减少时间和空间上的损失。

创意/价值

1. 我们分析了117项针对粮食损失和废物量化的研究。

2. 与上游食品供应链相比，下游食品供应链的研究更多。

3. 发达国家食品供应链的案例研究更为丰富。

4. 量化食物损失和浪费的主要指标是重量。
