提高粮食供应链的效率已被确定为加强粮食安全的一个重要手段，同时减少对自然资源的压力。充分的粮食损失和浪费管理（FLW）已被提议作为实现这些目标的一种方法。本研究的主要假设是，考虑到营养和经济成本，饮食习惯的“强烈波动和短期变化”可能对潜在的FLW产生和管理以及温室气体排放产生重大影响。由于新型冠状病毒COVID-19疫情爆发，西班牙政府实施了特殊的封锁措施，食品生产和消费系统发生了重大变化，必须进行适当研究，以便从经验教训中提出战略。以西班牙为案例研究，方法学方法包括对西班牙食物篮子的投入和产出进行深入分析，通过物质流分析进行供应链分析，以及进行经济和全面的营养评估，所有这些都是在生命周期思维方法下进行的。结果显示，在COVID-19封锁的最初几周内，整体FLW生成量没有显著调整，但发生了从家庭外消费到家庭的部分重新分配（家庭FLW增加12%）。此外，经济影响（+11%）、温室气体排放（+10%）和营养成分（-8%）完成了COVID-19爆发对FLW产生和管理的多变量影响概况。因此，本研究再次强调，旨在减少流动性废物的措施，特别是在家庭部门，对于更好地利用粮食剩余和流动性废物预防和控制至关重要，使我们能够应对未来不可预见的情况。(C)2020 Elsevier B.

Improving the food supply chain efficiency has been identified as an essential means to enhance food security, while reducing pressure on natural resources. Adequate food loss and waste (FLW) management has been proposed as an approach to meet these objectives. The main hypothesis of this study is to consider that the "strong fluctuations and short-term changes" on eating habits may have major consequences on potential FLW generation and management, as well as on GHG emissions, all taking into account the nutritional and the economic cost. Due to the exceptional lockdown measures imposed by the Spanish government, as a consequence of the emerging coronavirus disease, COVID-19, food production and consumption systems have undergone significant changes, which must be properly studied in order to propose strategies from the lessons learned. Taking Spain as a case study, the methodological approach included a deep analysis of the inputs and outputs of the Spanish food basket, the supply chain by means of a Material Flow Analysis, as well as an economic and comprehensive nutritional assessment, all under a life cycle thinking approach. The results reveal that during the first weeks of the COVID-19 lockdown, there was no significant adjustment in overall FLW generation, but a partial reallocation from extra-domestic consumption to households occurred (12% increase in household FLW). Moreover, the economic impact (+11%), GHG emissions (+10%), and the nutritional content (-8%) complete the multivariable impact profile that the COVID-19 outbreak had on FLW generation and management. Accordingly, this study once again highlights that measures aimed at reducing FLW, particularly in the household sector, are critical to make better use of food surpluses and FLW prevention and control, allowing us to confront future unforeseen scenarios.
