Abstract

The COVID-19 pandemic exposed significant vulnerabilities in systems of production and consumption. In particular, the economic and social implications of the pandemic highlighted the urgent need for more sustainable and less impactful practices of food production and consumption. Through a systematic literature review, this paper seeks to assess how the pandemic affected the phenomenon of food waste, with the aim of assessing whether the pandemic stimulated changes amongst food system actors, especially consumers. The findings indicate that consumers generally reported behavioural changes during the pandemic and claimed to have adopted sustainable practices that could contribute to reducing food waste. The results also reflect the rapid diffusion of practices such as food delivery during the pandemic, which requires further investigation in terms of its effects on the environment. Simultaneously, supply–demand shocks and disruptions were reported in the areas of production, processing, and retailing, suggesting the occurence of ripple effects. A call is made for greater resilience in the food system, through the adoption of sustainable and less impactful practices, supported by policy.

COVID-19对食物浪费的影响综述

2019冠状病毒病大流行暴露了生产和消费系统的重大脆弱性。特别是，这一大流行病的经济和社会影响突出表明，迫切需要采取更具可持续性和影响较小的粮食生产和消费做法。通过系统的文献综述，本文旨在评估大流行如何影响食物浪费现象，目的是评估大流行是否刺激了粮食系统参与者，特别是消费者之间的变化。调查结果表明，消费者普遍报告在大流行期间行为发生了变化，并声称采取了有助于减少食物浪费的可持续做法。调查结果还反映出疫情期间送餐等做法的迅速扩散，这需要进一步调查其对环境的影响。同时，据报道，生产、加工和零售领域出现了供需冲击和中断，表明出现了连锁反应。呼吁在政策支持下，通过采用可持续和影响较小的做法，提高粮食系统的抵御力。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
