摘要

在大多数国家,家庭产生的食物浪费比供应链上其他环节的总和还要多。确定哪些家庭造成的食物浪费最多,对于设计和实施减少食物浪费的有效干预措施非常重要。然而,以往关于社会人口特征和食物管理行为对家庭食物浪费影响的研究结果并不一致,而且往往依赖于自我报告的食物浪费数据。在这项研究中,我们使用废物成分分析检查了1783个英国家庭的社会人口统计学和食物管理行为与直接测量食物浪费的关系。我们的研究结果表明,家庭规模、年龄和教育程度对食物浪费水平有显著影响,拥有大学学位的人浪费的食物较少,这与之前分析自我报告的食物浪费水平的研究相反。此外,购买适量食物、重复利用剩饭剩菜和从冰箱中解冻食物的行为可以调解年龄与食物浪费之间的关系。虽然购买适量的食物和重复利用剩饭剩菜与减少食物浪费有关,但善于解冻的家庭往往浪费更多的食物,这是一个有趣的、以前未被报道过的发现。我们的研究结果表明,未来的行为干预应关注这些重要的社会人口因素和食物管理行为,以减少家庭食物浪费。

Is that the way the cookie crumbles? Variation in household food waste by socio-demographics and food management behaviours
Households produce more food waste than the rest of the supply chain combined in most countries. Identifying which households contribute most to food waste is important for designing and implementing effective interventions to reduce food waste. However, previous findings on the impact of socio-demographic characteristics and food management behaviours on household food waste are inconsistent and often rely on self-reported food waste data. In this study, we examined the association of socio-demographics and food management behaviours with directly measured food waste in 1783 UK households using waste compositional analysis. Our findings indicate that household size, age, and education significantly influence food waste levels, with individuals holding a university degree wasting less food, contrary to previous studies that analysed self-reported food waste levels. Additionally, the behaviours of purchasing the right amount of food, reusing leftovers, and defrosting items from the freezer are found to mediate the relationship between age and food waste. While purchasing the right amount of food and reusing leftovers are associated with lower food waste, households better at defrosting tend to waste more food, an intriguing and previously unreported finding. Our results suggest that future behavioural interventions should focus on these significant socio-demographic factors and food management behaviours to reduce household food waste.

期刊介绍: Sustainable production and consumption refers to the production and utilization of goods and services in a way that benefits society, is economically viable, and has minimal environmental impact throughout its entire lifespan. Our journal is dedicated to publishing top-notch interdisciplinary research and practical studies in this emerging field. We take a distinctive approach by examining the interplay between technology, consumption patterns, and policy to identify sustainable solutions for both production and consumption systems.
