Food waste prevention and reduction are an economic, social and environmental concern included among the 17 Sustainable Development Goals (SDGs) within Agenda 2030 for Sustainable Development. The third target under SDG 12 (Target 12.3) on Responsible Production and Consumption aims to halve food waste by 2030 at retail and consumer levels, considering that more than half of its quantity is generated by final consumers, both indoor and outdoor. However, the Covid-19 pandemic outbreak at the beginning of 2020 imposed several food consumption behaviors and lifestyle changes: food service facilities (e.g., restaurants, pubs, cafés, hotels, resorts) have been closed roughly all over the world, generating a sharp domestic consumption and an expected increase in household waste. The authors conducted an explorative research through the food diary approach. The purpose of this paper is to have a better understanding of household food consumption and wastage trends during Covid-19 pandemic testing, as well as food diary methodology strengths and weaknesses. Food diaries, even with their intrinsic limitations and biases, represent a valuable technique to obtain detailed qualitative and quantitative knowledge on daily food consumption and consumers' behavior. Through the limited but significant results achieved, the authors highlight the logistics of the methodology and the food waste generation trends among a small sample of Italian families during the Covid-19 pandemic. Further, healthier work-life balances, adequate time management and smart food delivery seem to be good opportunities for food waste reduction in households.

PurposeGiven the importance of food waste in the economic, social, health and environmental dimensions, the purpose of this work is to detect, through a systematic and configurative literature review on food-waste-measurement methodologies, the global approaches, characteristics, limitations, opportunities and results applied within the literature. The analysis of these papers provides useful information about how far we are from international action plans and, therefore, how we need to direct programs and policies to measure and reduce food waste and ensure food security and food safety.Design/methodology/approachThe authors have conducted a systematic, configurative literature review on food waste measurement methodologies applied only within empirical studies published in academic peer-reviewed scientific journals. Based on the Commission Delegated Decision (EU) 2019/1597 of May 3, 2019 (OJEU, 2019) regarding common methodologies and minimum quality requirements for the homogeneous assessment of food waste quantities and composition, the authors investigated the issue on Web of Science Core Collection (WoS) from June 2000 to June 2020. The authors researched keywords within article titles, abstracts and author keywords by utilizing 34 different research strings.FindingsThe proposed review particularly refers to following topics: measurement methodologies applied according to the Commission Delegated Decision (EU) 2019/1597; editorial placement and publication timeline; geographical area; food supply-chain stage and publication journals; and the main features, limitations, opportunities and results for each measurement methodology as presented by authors. Among the first 48,000 results, only 58 academic articles are perfectly in line with the aim of the review, highlighting the lack of standardized methodologies, the limits of those proposed and the deficiency of comparable results to achieve sustainable international goals.Originality/valueThe proposed review is one of the few concerning food waste measurement methodologies. Food waste measurement is essential to rebalance the actual inadequate food system and to switch it toward a fair, healthy and environmentally friendly one, thereby (1) managing the human nutrition system paradox of hungry, undernourished and over-weight people; (2) reducing food insecurity; (3) ensuring each living being's access to healthy, nutritious and sustainable food; and (4) reducing environmental impacts (neutral or positive impact) and the loss of biodiversity and mitigating climate change.

The reduction of food waste, especially in households where more than half of its global quantity is generated, has become an increasing economic, social and environmental concern, and represents one of the 17 Sustainable Development Goals within the Agenda 2030 for Sustainable Development. In this context, the Covid-19 lockdown has significantly changed life, work and food consumption habits all over the world, highlighting food waste as a multi-sectorial issue. 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”. Through an online questionnaire and the application of a k-means clustering model, the authors focus on four emerging constructs in terms of food consumption and food waste habits after the Covid-19 lockdown at household level. Among three theoretical clusters, results have highlighted: (i) the paradox of the “green wasters”, which declared a high level of awareness of the food waste issue but also generates huge amounts of thrown away food; (ii) the “positive unawareness” of the “red wasters”, which have a slight notion of environment and sustainability but waste low quantities of food; (iii) the consistency of the “blue wasters”, which know of the food waste issue and convert theory into practice.

Barley is an important cereal worldwide cultivated since about 10,000 years. Barley crop is the fourth most important cereal in the world, after wheat, corn, and rice. It could be a food source for millions of people even though today it is mainly used as animal feed and brewing. So, recently, more than 70% of barley crop has been used for feed; about 21% has been intended to malting, brewing, and distilling industries; lesser than 6% has been consumed as human food. In addition, a growing interest in renewable energy has led to the modest use of barley grain for the production of fuel ethanol. The prominence of barley as food is mainly due to its potentialities in the production of healthy food, as an excellent source of dietary fiber, and a functional food ingredient such as β-glucan. The purpose of this chapter is to carry out an analysis of barley market and to present, in summary, its principal uses.
