The factors that may influence FW.

Sustainability issues such as food insecurity, climate change, land degradation, economic development and food waste are the actual most important challenges at the global level. Among them, the food waste (FW) challenge has a great magnitude, emphasizing the importance of examining this issue. Specifically, there is a need to focus on the household level. Thus, this study aims to investigate and identify the main factors influencing FW household behaviors on which policymakers and stakeholders could outline specific and sustainable strategies. Starting from a large number of published studies on this subject with a similar aim but focusing on specific Countries or contexts, the goal of our study is achieved through the implementation of a systematic literature review followed by a bibliometric review using the VOSviewer software. The selected query generated a total of 235 matching papers from which only 111 papers were collected for the bibliometric review because of the inclusion criteria. The analysis showed the existence of four major research strands: the largest one analyses the antecedents of behavior during food management, including the implementation of the Theory of Planned Behavior (TPB). Other detected topics are the economic impact of FW, the effects generated by the Covid-19 pandemic on consumer behaviors, and finally, the environmental and social effects of FW. The objective of this study is to investigate and identify the main factors influencing FW household behaviors. The obtained output represents useful information for policymakers and stakeholders to outline specific and sustainable strategies to reduce FW.

粮食不安全、气候变化、土地退化、经济发展与食物浪费等可持续性议题，是全球层面最为关键的实际挑战。其中，食物浪费（Food Waste, FW）所带来的挑战规模庞大，凸显了开展该议题研究的重要性，而聚焦家庭层面的研究尤为必要。据此，本研究旨在探究并识别影响家庭食物浪费行为的核心影响因素，以供政策制定者与利益相关方据此制定针对性且可持续的应对策略。
现有同类主题的已发表研究数量众多，但多聚焦特定国家或研究场景。为此，本研究通过开展系统文献综述，并结合VOSviewer软件进行文献计量分析，以此达成研究目标。本次检索共匹配得到235篇相关文献，依据纳入标准最终筛选出111篇用于本次文献计量分析。
分析结果显示存在四大主要研究方向：规模最大的分支聚焦食物管理环节行为的前置影响因素，其中涵盖计划行为理论（Theory of Planned Behavior, TPB）的应用；其余研究主题包括食物浪费的经济影响、新冠疫情对消费者行为的影响，以及食物浪费所带来的环境与社会效应。
本研究的核心目标仍为探究并识别影响家庭食物浪费行为的关键因素，所得结果可为政策制定者与利益相关方制定针对性的可持续食物浪费削减策略提供有效参考。
