The COVID-19 outbreak created one of the largest pandemics globally, with the world health organization (WHO) declaring several measures, including restriction of movement to curtail the spread of the virus. Reducing food waste is critical to achieving healthy nutrition and sustainability in food systems. In this regard, private households have consistently been regarded as key actors in food waste generation. Hence, this study examined the effects of the COVID-19 pandemic on food waste in homes. A total of 1098 respondents were asked questions on how the pandemic affected their food preparation and consumption pattern, food purchasing and food waste. Compared with the situation before COVID19, there is a significant increase in kitchen spending and bread-making at home. Moreover, food waste generation and the frequency of eating out and food purchasing were reduced. Waste generation was higher in bakery products, left-over foods, and fruits and vegetables. Respondents suggested prudent meal preparation and consumption, increased awareness, and food purchasing restrictions as measures to reduce food waste. Overall, the pandemic has led to more stringent planning in household spendings and attitudinal changes regarding food preparation and consumption, resulting in a significant reduction in food waste and may have contributed to curtailing the spread of the COVID-19 virus. © 20222,International Journal on Food System Dynamics.

新冠肺炎疫情造成了全球最大的流行病之一,世界卫生组织(世卫组织)宣布了几项措施,包括限制人员流动以遏制病毒的传播。减少食物浪费对于实现粮食系统的健康营养和可持续性至关重要。在这方面,私人家庭一直被视为产生食物浪费的关键行为者。因此,本研究调查了COVID-19大流行对家庭食物浪费的影响。共有1098名答复者被问及大流行如何影响他们的食物制备和消费模式、食物购买和食物浪费。与covid - 19之前的情况相比,厨房支出和家庭面包制作大幅增加。此外,食物浪费的产生以及外出就餐和购买食物的频率也有所减少。烘焙食品、剩菜、水果和蔬菜产生的废物量更高。受访者建议谨慎备餐和消费,提高意识,以及限制食品购买,作为减少食物浪费的措施。总体而言,大流行导致家庭支出规划更加严格,对食物制备和消费的态度也发生了变化,从而大大减少了食物浪费,并可能有助于遏制COVID-19病毒的传播。©20222,国际食品系统动力学杂志。版权所有。

Transforming Developing Countries Agrifood Value Chains 发展中国家农业食品价值链转型
Pub Date : 2021-10-15 DOI: 10.18461/IJFSD.V12I4.96

The global agrifood trade is highly reliant on developing countries, which affects value chain transformation and which often results in an imbalance of governance and value addition. In order to address this imbalance and increase the overall value creation, this paper develops and empirically tests a framework for agrifood value chain transformation in developing countries. The research employs a qualitative methodology to explore the proposed framework, which is based on a value chain maturity assessment of current practice and identification of a transformation route. Three primary value chain maturity levels in developing countries are established: traditional, managed, and best practice. Each level is determined using key indicators relating to governance (vertical-horizontal coordination, and information flow) and value addition (value orientation, safety, and quality). The application of this framework to Indonesia’s cashew nuts value chain reveals a mix of traditional and managed practices. The short-medium term transformation focuses on enabling farmers, as the decoupled actors, to advance from a traditional to a more managed chain. Further, the major wholesaler and exporter are identified as highly influential in driving the transformation process. The long-term transformation focuses on developing best practices regarding branded value addition and collaborative governance. This framework offers a novel value chain transformation approach based on a maturity assessment technique leading to the identification of transformation routes. This method takes a holistic transformation approach via the evaluation all the value chain actors’ governance and value-addition capabilities. Follow-up research is required to identify the enablers and barriers of globalised value chain transformation, especially with respect to sustainability.
全球农产品贸易高度依赖发展中国家,这影响了价值链转型,往往导致治理和增值失衡。为了解决这一不平衡,增加整体价值创造,本文开发并实证检验了发展中国家农产品价值链转型框架。该研究采用定性方法来探索所提出的框架,该框架基于对当前实践的价值链成熟度评估和转型路线的确定。在发展中国家建立了三个主要的价值链成熟度水平:传统、管理和最佳实践。每个层次都是使用与治理(垂直水平协调和信息流)和附加值(价值导向、安全和质量)相关的关键指标来确定的。将这一框架应用于印度尼西亚的腰果价值链,揭示了传统和管理实践的结合。中短期转型的重点是使农民作为脱钩的参与者,从传统的链条向更有管理的链条推进。此外,主要批发商和出口商被认为在推动转型过程中具有很大的影响力。长期转型的重点是开发有关品牌增值和协作治理的最佳实践。该框架提供了一种基于成熟度评估技术的新的价值链转换方法,从而确定了转换路线。该方法通过评估所有价值链参与者的治理和增值能力,采用了一种整体转型的方法。需要进行后续研究,以确定全球化价值链转型的推动因素和障碍,特别是在可持续性方面。

This study aims to identify important factors that directly influence value chain performance (quality, responsiveness, flexibility and efficiency), which are explained by value chain integration (collaboration, commitment, coordination and joint decision-making) in the case of unexpected risk (the COVID-19 pandemic). This study contributes to maintaining the business linkage model among farmers – cooperatives – enterprises in the case of the COVID-19 pandemic and quickly recovering after the COVID-19 pandemic. Structural equation modelling (SEM) was used for data analysis following an iterative process based on theoretical and empirical analyses to obtain a structural model fit and test the research hypothesis. The findings indicate that the VCI positively influenced the VCP of Chu-mango business linkages at the 1% significance level through coordination (Beta = 0.345; construct reliability (CR) = 3.272), collaboration (Beta = 0.289; CR = 3.128), and joint decision-making (Beta = 0.324; CR = 3.245). This study provides empirical data on the relationship between VCI and VCP through the Chu -mango value chain in Dong Thap Province during the COVID-19 pandemic to raise awareness from stakeholders and encourage value chain thinking to improve performance. This result may pave the way for relevant policymakers to look for policies and strategies for better inclusiveness of stakeholders to show the importance of the VCI in improving the performance. Moreover, the study is an empirical case contributing to the agribusiness value chain in a developing country; it applies the agribusiness value chain of the tropical fruit domain and can be used for other agricultural products in other cases of unexpected risks.
本研究旨在确定直接影响价值链绩效(质量、响应能力、灵活性和效率)的重要因素,在出现意外风险(新冠肺炎大流行)的情况下,通过价值链整合(协作、承诺、协调和联合决策)来解释这些因素。这项研究有助于在新冠肺炎大流行的情况下维持农民-合作社-企业之间的商业联系模式,并在新冠肺炎大流行后迅速恢复。结构方程建模(SEM)用于数据分析,遵循基于理论和经验分析的迭代过程,以获得结构模型拟合并检验研究假设。研究结果表明,VCI通过协调(贝塔=0.345;结构可靠性(CR)=3.272)、协作(贝塔=0.289;CR=3.128)、,和联合决策(Beta=0.324;CR=3.245)。本研究提供了新冠肺炎大流行期间东塔省通过楚-芒果价值链的VCI和VCP之间关系的实证数据,以提高利益相关者的意识,鼓励价值链思维以提高绩效。这一结果可能为相关决策者寻找更好地包容利益相关者的政策和战略铺平道路,以表明VCI在提高绩效方面的重要性。此外,该研究是一个有助于发展中国家农业综合企业价值链的实证案例;它适用于热带水果领域的农业综合企业价值链,并可用于其他农产品的其他意外风险情况。

The purpose of this study is to empirically assess whether the social-symbolic meaning of eating habits is constructed within cultures. The analysis is based on the sociological approaches of Bourdieu´s theory. To answer the question, data from an on-line survey (n=319; carried out in the Czech and Ukraine) are compared using multi-sample measurement model. Results indicate the effect of social structures on individual perceptions and practices through habitus. The differences rely on the revitalization of local food, food arts, and market in Czechia. These findings have several marketing and advertising implications.

Rapid growth in dairy consumption and food scandals in India in the 2000s increased awareness of food safety issues among consumers and policymakers. This led to the introduction of new standards. However, there is little information about how they affected farm-level activities and whether value chains played any role. Our paper addresses these questions using a two-round panel survey of dairy farms in Punjab and Andhra Pradesh. We find significant improvements in adoption of farm-level hygienic practices, especially in Punjab. Value chain innovations do not play a significant role in stimulating safety and quality improvements among dairy smallholders in India.
21世纪初,印度乳制品消费的快速增长和食品丑闻提高了消费者和政策制定者对食品安全问题的认识。这导致了新标准的引入。然而,关于它们如何影响农场层面的活动以及价值链是否发挥了任何作用的信息很少。我们的论文通过对旁遮普邦和安得拉邦奶牛场的两轮小组调查来解决这些问题。我们发现,在采用农场级卫生做法方面有了显著改善,尤其是在旁遮普邦。价值链创新在促进印度小农户的安全和质量改善方面没有发挥重要作用。

In the field of agri-food, impact assessments to support policy decision-making are often based on simulations delivered by models. The increasing complexity of policies affecting the agri-food sector requires improving the capacities of current models, connect ing or redesigning them to deliver forward-looking insights on policy objectives. The EU-Project ‘Support for Policy Relevant Modelling of Agriculture’ (SUPREMA) has identified upcoming needs in the research and policy agenda, while exploring the feasibility of those potential modelling exercises by testing the existing tools. The assessment has pointed out necessities for model extensions and development of new tools. Besides, it has revealed the potential of model integration and collaboration to supplement the outcomes of individual models. This is supported in view of the food system approach that is becoming the fundamental framework for analysing the dynamics of the agri -food sector when considering it from a broad perspective. This paper describes shortly how the assessment was conducted and presents the outcomes and lessons learnt from the project. It pays special attention to the challenges and the policy priorities that are expected to become important issues in the policy agenda in the coming years.
在农业食品领域,支持政策决策的影响评估通常基于模型提供的模拟。影响农业食品部门的政策日益复杂,需要提高现有模型的能力,将它们连接起来或重新设计,以提供有关政策目标的前瞻性见解。欧盟项目“支持农业政策相关建模”(SUPREMA)确定了研究和政策议程中即将出现的需求,同时通过测试现有工具探索这些潜在建模练习的可行性。评估指出了模型扩展和开发新工具的必要性。此外,它还揭示了模型集成和协作的潜力,以补充单个模型的结果。这一点得到了粮食系统方法的支持,该方法正在成为分析农业食品部门动态的基本框架,当从广泛的角度考虑它时。本文简要介绍了评估是如何进行的,并介绍了从项目中获得的成果和教训。它特别关注预计将成为未来几年政策议程中重要问题的挑战和政策优先事项。

Applying the HEXACO Model of Personality to German Livestock Farmers: Item Scale Validation, Personality Structure and Influence on Participation in Livestock Certification Schemes HEXACO人格模型在德国畜牧农户中的应用:项目量表验证、人格结构及其对畜牧认证计划参与的影响
Pub Date : 2021-08-18 DOI: 10.18461/IJFSD.V12I3.87
I. Schröter, M. Mergenthaler
Decisions made by farmers have impacts beyond the farm boundary, because farmers are the first link in the food supply chain. For this reason, understanding their decision-making behaviour may be of interest to all stakeholders of food systems. Since there is considerable evidence that personality traits may affect decision-making behaviour, we investigated personality traits utilising the HEXACO model of personality in a sample of 244 German livestock farmers. Based on comparisons with data obtained from existing literature that investigated the HEXACO personality traits using community samples and with preliminary data from an own community sample, we found that the livestock farmers differed from the general population. The farmers had higher scores in Honesty-Humility and Conscientiousness and were more emotionally stable. Results of a multinomial logistic regression model showed that personality traits influenced farmers’ decisions to participate in particular livestock certification schemes. While high Conscientiousness increased the probability of participating in conventional animal welfare schemes, high Openness to Experience facilitated participation in organic schemes. However, the results of a confirmatory factor analysis indicated that the German version of the short item scale used to measure the personality traits of the farmer sample should be partially modified. Even though the results should be understood rather as first indications and as a basis for further research, our findings extend the understanding of farmers’ personality and provide information on underlying factors of farmers’ decision-making related to participation in livestock certification schemes. They could help to better align support strategies, e.g. for more environmentally and animal-friendly production, with the personality of farmers.
农民所做的决定的影响超出了农场边界,因为农民是食品供应链的第一个环节。因此,了解它们的决策行为可能对粮食系统的所有利益攸关方都有好处。由于有大量证据表明人格特质可能影响决策行为,我们利用HEXACO人格模型对244名德国畜牧农民的人格特质进行了调查。通过与现有社区样本调查HEXACO人格特征的文献数据和社区样本的初步数据进行比较,我们发现畜禽养殖户与一般人群存在差异。农民在诚实谦卑和尽责性方面得分更高,情绪更稳定。多项逻辑回归模型的结果表明,个性特征影响了农民参与特定牲畜认证计划的决策。高度的责任心增加了参与传统动物福利计划的可能性,而高度的经验开放性促进了参与有机计划。然而,验证性因子分析的结果表明,用于测量农民样本人格特质的德文短项目量表需要进行部分修改。尽管这些结果应该被理解为初步迹象,并作为进一步研究的基础,但我们的研究结果扩展了对农民个性的理解,并提供了有关农民参与牲畜认证计划决策的潜在因素的信息。它们可以帮助更好地将支持战略(例如促进对环境和动物更友好的生产)与农民的个性结合起来。

For this reason, understanding their decision-making behaviour may be of interest to all stakeholders of food systems. Since there is considerable evidence that personality traits may affect decision-making behaviour, we investigated personality traits utilising the HEXACO model of personality in a sample of 244 German livestock farmers. Based on comparisons with data obtained from existing literature that investigated the HEXACO personality traits using community samples and with preliminary data from an own community sample, we found that the livestock farmers differed from the general population. The farmers had higher scores in Honesty-Humility and Conscientiousness and were more emotionally stable. Results of a multinomial logistic regression model showed that personality traits influenced farmers’ decisions to participate in particular livestock certification schemes. While high Conscientiousness increased the probability of participating in conventional animal welfare schemes, high Openness to Experience facilitated participation in organic schemes. However, the results of a confirmatory factor analysis indicated that the German version of the short item scale used to measure the personality traits of the farmer sample should be partially modified.

External shocks, such as disease occurrence, can be very disruptive in complex food producing value chains. To analyze this, a vertically linked dynamic partial equilibrium model was used to analyze market effects of outbreaks of Highly Pathogenic Avian Influenza (HPAI) in The Netherlands. Various shock inducing scenarios were analyzed, e.g control strategy, demand shocks and trade bans. The results showed that in densely populated poultry areas (1) market effects usually outweigh direct control costs, (2) vaccination could help mitigating total disease costs, particularly if (3) channeling to industrial processing is included. Moreover, large, and in some cases opposing differences in market effects between the various stakeholders could be observed. The result suggest a number of important policy factors that should be considered in HPAI control, e.g. the poultry density, the production structure and differentiation of stakeholders, the dependency on international trade and the potential capacity of industrial processing of eggs. General implications for other food producing value chains are discussed.
外部冲击,如疾病的发生,可能会对复杂的食品生产价值链造成很大的破坏。为了分析这一点,使用了一个垂直链接的动态部分平衡模型来分析荷兰爆发的高致病性禽流感(HPAI)的市场效应。分析了各种引发冲击的情景,如控制策略、需求冲击和贸易禁令。结果表明,在家禽密集地区,(1)市场影响通常超过直接控制成本,(2)疫苗接种有助于降低疾病总成本,特别是如果(3)将其纳入工业加工。此外,可以观察到不同利益相关者之间市场效应的巨大差异,在某些情况下甚至是相反的差异。研究结果表明,在控制高致病性禽流感时应考虑一些重要的政策因素,如家禽密度、生产结构和利益相关者的差异、对国际贸易的依赖以及鸡蛋工业加工的潜在能力。讨论了对其他粮食生产价值链的一般影响。

Food value chain businesses form alliances with horizontal and/or vertical partners to take collective action to either overcome or ameliorate chain failure, or to take advantage of new opportunities available due to innovations in products or processes. The desired outcomes from the collective action would no t be possible to achieve if these businesses acted independently. While such alliances and collaborations may take many forms, depending on the degree of commitment, the kind of governance and infrastructure linkages, they can often be thought of as “clubs ” for the purpose of economic analysis. Several different types of clubs can be identified, thus the path to collective action chosen by clubs may vary according to existing capabilities and the scope for collaboration, particularly in relation to the potential for value-creating innovation. The result of the collective action is the provision of a chain good or service, which usually leads to greater and more valuable chain coordination. By collectively identifying, funding and acting to capture positive externalities associated with innovation, businesses in many parts of a food value chain can widen opportunities to increase whole-of-chain surplus as well as private profits. In this paper five mini-case studies are presented to demonstrate the breadth of past collective actions undertaken by businesses in food value chains, two in Europe and three in Australia. These are the Euro Pool System, and Global Standards certification in Europe and globally, as well as Meat Standards Australia, an Australian beef organic producer alliance (OBE Organic®), and the supply of food to households during Covid-19 lockdown in Australia. Each case study yields insights into the rationale of how businesses in different food value chains in different countries have acted as a club to use their joint resources to internalise positive innovation and coordination externalities.
食品价值链企业与横向和/或纵向合作伙伴结成联盟,采取集体行动克服或改善链故障,或利用产品或工艺创新带来的新机会。如果这些企业独立行动,就不可能实现集体行动的预期结果。尽管根据承诺程度、治理类型和基础设施联系,这种联盟和合作可能有多种形式,但出于经济分析的目的,它们通常可以被视为“俱乐部”。可以确定几种不同类型的俱乐部,因此俱乐部选择的集体行动路径可能因现有能力和合作范围而异,特别是在创造价值创新的潜力方面。集体行动的结果是提供连锁商品或服务,这通常会导致更大、更有价值的连锁协调。通过集体识别、资助和采取行动捕捉与创新相关的正外部性,食品价值链许多部分的企业可以扩大增加全链盈余和私人利润的机会。本文介绍了五个小型案例研究,以证明企业在食品价值链中过去采取的集体行动的广度,其中两个在欧洲,三个在澳大利亚。这些是欧洲池体系、欧洲和全球的全球标准认证,以及澳大利亚肉类标准、澳大利亚牛肉有机生产商联盟(OBE organic®),以及澳大利亚新冠肺炎封锁期间向家庭供应的食品。每一个案例研究都深入了解了不同国家不同食品价值链中的企业如何作为一个俱乐部,利用其联合资源将积极的创新和协调外部性内化的基本原理。
