Caring more about food: The unexpected positive effect of the COVID-19 lockdown on household food management and waste (September 2020)

During the COVID-19 outbreak, food management and consumption habits changed dramatically due to lockdown restrictions imposed by governments. This study investigated how these changes in the daily lives of consumers influenced the generation of food waste at household level. Participants were Italian and asked to self-estimate the percentage of food their households wasted before and during the lockdown and to explain their food management habits.

Over-ordering and food waste: The use of food delivery apps during a pandemic (July 2021)

There is a paucity of research on the role of food delivery apps (FDAs) in food waste generation. This gap needs to be addressed since FDAs represent a fast-growing segment of the hospitality sector, which is already considered to be a key food waste generator globally. Even more critically, FDAs have become a prominent source of ordering food during the COVID-19 pandemic. The present study addresses this need by examining the antecedents of FDA users’ food ordering behavior during the pandemic that can lead to food waste.

Assessment of household food waste management during the COVID-19 pandemic in Serbia: a cross-sectional online survey (September 2021)

This paper investigates the state of food waste management in Serbia and COVID-19’s direct effect on consumer awareness, food consumption, and food waste behaviors. There were three major objectives: 1) to investigate the state of food waste management in Serbia and test the hypothesis that household food waste in Serbia is low and there is a positive attitude toward food waste prevention; 2) To investigate the immediate impact of COVID-19 on consumer awareness and behaviors related to food waste, and to test the hypothesis that consumers have increased their food waste during the pandemic; and, 3) to test the hypothesis that decreased grocery stores trips and increased stockpiling and panic buying, increased food waste during the COVID-19 pandemic.

Has the COVID-19 pandemic changed food waste perception and behavior? Evidence from Italian consumers (June 2021)

The present paper, through an online-based questionnaire among 831 respondents from Italy and the application of the cumulative logit model, investigates consumer behavior after the lockdown with reference to unpredictable lifestyles, improvements in smart food delivery and never-experienced time management. Results illustrate that always-at-home consumers (forced to stay at home 24 h a day) are more likely to perceive food waste and reduce its amount, whereas discontinuous smart working makes food purchase, preparation and consumption activities even more stressful and complex.

Households’ Food Waste Behavior at Local Scale: A Cluster Analysis after the COVID-19 Lockdown (March 2021)

This paper explores current attitudes, perception and behavioral patterns related to food waste reduction at domestic consumption at the local scale (Apulia region, Italy), with the aim of identifying different types of “food wasters” and illustrate new paths for sustainable food consumption and food waste approach after the COVID-19 lockdown. The authors investigate four constructs: 1) consumer environmental concern; 2) time management, distinguishing between shopping planning, diet planning, culinary activities management and time allotted for eating; 3) price/quantity consciousness; and 4) influence of the COVID-19 pandemic on food consumption and food waste behavior.

Food waste management during the COVID-19 outbreak: a holistic climate, economic and nutritional approach (November 2020)

The main hypothesis of this study is to consider that the ‘strong short-term fluctuations and changes’ of eating habits could have significant direct and/or indirect consequences in FLW generation and management. The COVID-19 outbreak, and the follow-on measures taken by the Spanish government to mitigate its effects, produced some retail and consumption disruptions. These could have major consequences on the potential generation and management of FLW, as well as on the GHG emissions associated with food production and consumption.

The quantity and composition of household food waste during the COVID-19 pandemic: A direct measurement study in Canada (June 2021)

A better understanding of household food wasting during the pandemic is needed to improve the management of waste and develop best practices for municipal waste management programs under crisis circumstances. A waste composition study was undertaken with 100 single-family households across the city of London, Ontario, Canada to determine the quantity and composition of household food waste disposed in June 2020, during the first wave of the COVID-19 pandemic. This study examines how household demographic, socio-economic, and neighbourhood food environment characteristics influence household food wasting.

COVID-19-Related Changes in Perceived Household Food Waste in the United States: A Cross-Sectional Descriptive Study (January 2021)

This study explored perceived household food waste changes during the COVID-19 pandemic and related factors. A total of 946 survey responses from primary household food purchasers were analyzed. The primary aims of the study were (1) to examine if perceived household food waste changed during the COVID-19 pandemic and (2) to explore whether lifestyle disruptions and changes in food-related behaviors influenced household food waste during the COVID-19 pandemic. In addition, the contribution of different food groups to household food waste changes during the COVID-19 pandemic was explored.

“Do I have enough food?” How need for cognitive closure and gender impact stockpiling and food waste during the COVID-19 pandemic: A cross-national study in India and the United States of America (January 2021)

This study conducted a cross-national survey in the US and India to investigate how individuals' levels of need for cognitive closure (NFC) relate to food stockpiling and waste during the COVID-19 pandemic. Through a sequential mediation model, they showed how individuals high in NFC did not perceive to have enough food at home, ending up buying more food than usual and, eventually, wasting more. The study also discusses how gender roles in different countries can correlate with the stockpiling and food waste processes.

“Stay at Home”: The Effects of the COVID-19 Lockdown on Household Food Waste in Colombia (October 2021)

The objective of this study is to analyze changes in food waste behavior during the COVID-19 lockdown in Colombia in 2020, applying the Theory of Planned Behavior (TPB).

The paper also evaluates whether it is appropriate or not to use the Theory of Planned Behavior (TPB) for predicting the intention and behavior regarding household food waste.

COVID-19 and food security | Increased food losses in Africa (Expert view) (July 2020)

In the current health and economic crisis triggered by COVID-19, regional markets in Africa have actually suffered very little from shortages. Certain traditional value chains have even proved their resilience, notably by switching to local distribution circuits. Nevertheless, the restrictive measures taken have affected supply chains and resulted in increased, and in some cases critical, levels of food losses in certain value chains.
