The impact of pre-empting dual food quality regulation on product reformulation and packaging 先发制人的双重食品质量法规对产品配方和包装的影响
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-09-01 DOI: 10.1016/j.foodpol.2024.102707

The objective of this paper is to analyse the changes in the occurrence of the Differences in Composition of Seemingly Identical, branded food Products (DC-SIP) – also known as “dual food quality” – in the EU and the role of the Unfair Commercial Practices Directive (UCPD) in affecting the food industry’s packaging and recipe formulation choices of branded food products. The occurrence of DC-SIP has decreased from 31 % in 2018/2019 to 24 % in 2021. Our regression results show that companies are more likely to alter the front packaging rather than the composition of the products to address DC-SIP issues. The likelihood that changes in recipe reformulations and front packaging are introduced simultaneously is statistically significant but not all recipe reformulations are introduced jointly with changes in front packaging. Our results provide evidence that the UCPD regulation plays a role in companies reformulating recipes or/and changing the product packaging, but it is not a main driver. Companies often justify the composition differences in DC-SIP by differences in market conditions across Member States. The DC-SIP provisions in the UCPD give companies several options for addressing DC-SIP. For this reason, it is not a significant factor in impacting the companies' choices to reformulate or change the packaging of products.

本文旨在分析欧盟 "看似相同的品牌食品成分差异"(DC-SIP)--又称 "双重食品质量"--发生率的变化,以及《不公平商业行为指令》(UCPD)在影响食品行业品牌食品包装和配方选择方面的作用。DC-SIP 的发生率从 2018/2019 年的 31% 降至 2021 年的 24%。我们的回归结果显示,企业更有可能改变正面包装而非产品成分来解决 DC-SIP 问题。同时改变配方和正面包装的可能性在统计上是显著的,但并不是所有配方的改变都与正面包装的改变同时进行。我们的研究结果证明,UCPD 法规在企业重新配制配方或/和改变产品包装方面发挥了一定的作用,但并不是主要的驱动因素。企业往往以各成员国市场条件的不同来解释 DC-SIP 的成分差异。UCPD 中的 DC-SIP 条款为企业提供了解决 DC-SIP 问题的多种选择。因此,DC-SIP 并不是影响企业选择重新配制或改变产品包装的重要因素。

Integrating system dynamics to value chain analysis to address price volatility in the Indonesian chilli value chain 将系统动力学与价值链分析相结合,解决印度尼西亚辣椒价值链中的价格波动问题
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-31 DOI: 10.1016/j.foodpol.2024.102713

The price volatility observed in agricultural value chains presents a significant socio-economic challenge, particularly for smallholder farmers. The issue of price volatility in agricultural value chains is complex due to the dynamic and interconnected nature of these value chains. The objective of this study is to integrate system dynamics with value chain analysis in order to address price volatility in the Indonesian chilli value chain. In order to ensure stakeholder engagement and enhance the robustness of the proposed solutions, a participatory approach will be employed. The utilisation of system dynamics enables the quantitative simulation of the inherent dynamics of the chilli value chain, thereby facilitating both ex-ante and ex-post assessment of policy interventions. A collaborative process with stakeholders was employed to develop, test, and validate a system dynamics model that operates at both provincial and national levels. The findings demonstrate that the model accurately replicates the price volatility observed in the Indonesian chilli market. The key factors contributing to this volatility are seasonal production, disorganised market governance and high postharvest losses. The analysis of policy options indicates that while the importation of chillies can stabilise prices in the short term, it has a negative impact on the income of those involved in the value chain. More sustainable solutions to mitigate price volatility include the implementation of year-round planting and the enhancement of market governance. These strategies present potential avenues for achieving a more stable and equitable chilli market, offering valuable insights for broader agricultural value chain stability.

在农业价值链中观察到的价格波动是一个重大的社会经济挑战,尤其是对小农而言。由于农业价值链的动态性和相互关联性,这些价值链中的价格波动问题十分复杂。本研究的目标是将系统动力学与价值链分析相结合,以解决印度尼西亚辣椒价值链中的价格波动问题。为了确保利益相关者的参与并提高建议解决方案的稳健性,将采用参与式方法。利用系统动力学可以对辣椒价值链的内在动态进行定量模拟,从而便于对政策干预进行事前和事后评估。通过与利益相关者合作,开发、测试和验证了一个在省级和国家级运行的系统动力学模型。研究结果表明,该模型准确地再现了在印度尼西亚辣椒市场上观察到的价格波动。造成这种波动的关键因素是季节性生产、混乱的市场管理和收获后的高损失。对政策选择的分析表明,虽然进口辣椒可以在短期内稳定价格,但会对价值链中相关人员的收入产生负面影响。减缓价格波动的更可持续的解决方案包括实施全年种植和加强市场管理。这些战略为实现更加稳定和公平的辣椒市场提供了潜在的途径,为更广泛的农业价值链稳定提供了宝贵的见解。

Women improving nutrition through self-help groups in India: Does nutrition information help? 印度妇女通过自助小组改善营养状况:营养信息有帮助吗?
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-31 DOI: 10.1016/j.foodpol.2024.102716

Women’s self-help groups (SHGs) are an important platform for reaching poor women in India. Despite SHGs' women-focused programming, evidence of the impact of SHG-based interventions on nutrition outcomes is limited, and most evaluations of nutrition interventions have not examined intermediate outcomes along the impact pathways or outcomes for women themselves. This paper evaluates the effectiveness of an integrated agriculture-nutrition intervention delivered through women’s SHGs in five states in central and eastern India. The interventions involved the delivery of nutrition behavior change communication to groups through participatory approaches, community engagement around key issues, and the strengthening of collective organizations. Our analysis is based on three rounds of rich panel data on close to 2700 rural women and their households from eight districts in these five states and qualitative work from an accompanying process evaluation. Using difference-in-difference models with nearest neighbor matching methods, we present results on women’s anthropometry and diet-related outcomes.

We do not observe any improvements in women’s BMI or overall dietary diversity. Although more women in the nutrition intensification arm consumed animal source foods, nuts and seeds, and fruits, this was not enough to increase overall dietary diversity scores or the proportion of women achieving minimum dietary diversity. We measure intermediate outcomes along the program’s impact pathways and find improvements in household incomes, cultivation of home gardens, and utilization of government schemes but not in women’s empowerment. The lack of improvement in anthropometry and diets despite changes in some intermediate outcomes can be attributed to several factors such as low implementation intensity, poor facilitator capacity and incentives, the lack of relevance of the BCC topics to the average SHG member, and resource and agency constraints to adoption of recommended practices. Although we do not have data to test the parallel trends assumption and so do not interpret our results as causal, these findings do suggest that optimism about using group-based platforms needs to be tempered in resource-poor contexts.

在印度,妇女自助团体(SHGs)是帮助贫困妇女的重要平台。尽管自助团体的计划以妇女为重点,但基于自助团体的干预措施对营养结果影响的证据却很有限,而且大多数营养干预措施的评估都没有考察影响途径的中间结果或妇女本身的结果。本文评估了印度中部和东部五个邦通过妇女自助团体实施的农业-营养综合干预措施的效果。干预措施包括通过参与式方法向团体提供营养行为改变沟通、围绕关键问题开展社区参与以及加强集体组织。我们的分析基于三轮丰富的面板数据,涉及这五个邦八个地区的近 2700 名农村妇女及其家庭,以及配套的过程评估中的定性工作。我们利用差分模型和近邻匹配方法,得出了妇女的人体测量和饮食相关结果。虽然营养强化组中有更多的妇女摄入了动物源性食物、坚果和种子以及水果,但这并不足以提高总体膳食多样性得分或达到最低膳食多样性的妇女比例。我们沿着该计划的影响路径对中间结果进行了衡量,发现家庭收入、家庭菜园种植和政府计划利用率都有所提高,但妇女赋权却没有提高。尽管一些中间结果发生了变化,但人体测量和膳食却没有得到改善,这可归因于几个因素,如实施强度低、促进者能力和激励不足、BCC 主题与一般自助小组成员缺乏相关性,以及资源和机构对采用推荐做法的限制。虽然我们没有数据来检验平行趋势假设,因此不能将我们的结果解释为因果关系,但这些发现确实表明,在资源匮乏的情况下,对使用以小组为基础的平台的乐观态度需要有所收敛。

Nutrition education effects on food and nutrition security for women living with HIV/AIDS in Uganda 营养教育对乌干达感染艾滋病毒/艾滋病妇女的粮食和营养安全的影响
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-29 DOI: 10.1016/j.foodpol.2024.102715

Food and Nutrition Security (FNS) is one of the key global concerns yet in the face of HIV/AIDS, it is compromised. The significance of nutrition education targeted at women in promoting food and nutrition security cannot be overstated, considering their role in ensuring food and nutrition security for their household members. However, empirical evidence on the causal impact of nutrition education on food and nutrition status is limited to the individual level and very scanty for vulnerable groups such as HIV/AIDS-positive women. This study used a large dataset from a randomized control experiment with 3,200 women to investigate the effects of nutrition education on household behaviour and food nutrition outcomes. Results indicate that the intervention results in increasing the individual woman’s labour supply on-farm and diversifying crops grown by the household. Positive influences of nutrition education on dietary diversity are observed but were only significant at the household level. Individual women’s nutrition outcomes were strongly influenced by engagement in an income-generating activity or household’s market participation. As such, blending nutrition education interventions with initiatives that facilitate access to the needed nutritious foods such as on-farm diversification and activities that generate revenues from off the farm was recommended.

粮食和营养安全(FNS)是全球关注的主要问题之一,但在艾滋病毒/艾滋病面前,它却受到了损害。考虑到妇女在确保家庭成员食品和营养安全方面的作用,针对妇女的营养教育在促进食品和营养安全方面的意义怎么强调都不为过。然而,有关营养教育对食物和营养状况的因果影响的实证证据仅限于个人层面,对于艾滋病毒/艾滋病呈阳性的妇女等弱势群体而言则非常匮乏。本研究使用了一个有 3 200 名妇女参加的随机对照实验的大型数据集,以调查营养教育对家庭行为和食物营养结果的影响。结果表明,干预措施增加了妇女个人在农场的劳动力供应,并使家庭种植的作物多样化。营养教育对膳食多样性产生了积极影响,但仅在家庭层面具有显著性。参与创收活动或家庭参与市场对妇女个人的营养结果影响很大。因此,建议将营养教育干预措施与促进获得所需营养食品的举措相结合,如农场多样化和农场外创收活动。

Impact of crop commercialization on smallholder farmers’ resilience to shocks: Evidence from panel data for rural Southeast Asia 作物商业化对小农抵御冲击能力的影响:来自东南亚农村地区面板数据的证据
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-18 DOI: 10.1016/j.foodpol.2024.102709

We assess the impact of crop commercialization on the resilience to shocks of smallholder farmers and examine which groups of smallholders are more resilient from crop commercialization. We use balanced panel of 1,370 smallholders from Thailand and 1,497 smallholders from Vietnam collected in three survey waves for the empirical analysis. We employ a generalized structural equation model to estimate the (latent) variable of smallholders’ resilience. Then, we apply fixed-effects estimations with an instrumental variable and a control function approach to address the endogeneity concerns of crop commercialization in assessing the impact of commercialization on the resilience of smallholders. The results show that crop commercialization has a positive effect on smallholders’ resilience capacity. To examine which groups of smallholders are more resilient from crop commercialization, we apply an unconditional quantile regression model. The results show that crop commercialization has the highest impact on smallholders in 10th and 25th quantile groups of resilience capacity. Thus, crop commercialization should be stimulated to improve smallholders’ resilience to shocks. Besides, improving infrastructure for transportation and information and communication technology at the village level and the effectiveness of public governance at the national level could lead to a better resilience of smallholders.

我们评估了农作物商业化对小农户抵御冲击能力的影响,并研究了哪些小农户群体更能抵御农作物商业化的冲击。我们使用在三次调查中收集的来自泰国的 1,370 个小农户和来自越南的 1,497 个小农户的平衡面板进行实证分析。我们采用广义结构方程模型来估计小农户抗逆力的(潜在)变量。然后,在评估商业化对小农户抗逆力的影响时,我们采用固定效应估算法、工具变量法和控制函数法来解决作物商业化的内生性问题。结果表明,农作物商业化对小农户的抗灾能力有积极影响。为了研究哪些小农户群体从农作物商业化中获得更强的抗逆能力,我们采用了无条件量化回归模型。结果显示,农作物商业化对抗灾能力处于第 10 和第 25 个量级的小农户影响最大。因此,应鼓励作物商业化,以提高小农户抵御冲击的能力。此外,改善村一级的交通和信息通信技术基础设施以及提高国家一级公共治理的效率,也能提高小农户的抗冲击能力。

Development of the Food Systems Literacy Competencies Framework for youth: A modified Delphi study with experts 为青年制定食品系统扫盲能力框架:经修改的德尔菲专家研究
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-08 DOI: 10.1016/j.foodpol.2024.102702

Food systems have changed drastically in the last 50 years, are continuously globalizing, and are constantly responding to environmental, social, economic and political challenges. While a primary goal of food systems is to provide food security, food insecurity rates have continued to rise in recent years. To deal with these systemic problems, food systems experts call for food systems literacy. However, there are no common frameworks outlining what people should know about food systems, making it challenging to relay information into education and to the general population. As such, the aim of this research was to identify competencies for food systems literacy for youth in Canada. We conducted a 2-round modified Delphi study to achieve consensus on a list of key competencies for food systems literacy. Delphi studies allow for broad consultation of expert judgements to achieve consensus on complex issues. This resulted in a list of 50 key competencies for food systems literacy (out of 131 tested) across themes for Indigenous food systems, food systems activities (i.e., production to waste as well as some overarching and technology themes), sustainability, food security and governance. This Framework of competencies is the first of its kind and will be useful for directing how food systems can be integrated into education as well as be a guide for food systems literacy evaluation tools.

粮食系统在过去 50 年里发生了翻天覆地的变化,不断全球化,并不断应对环境、社会、经济和政治挑战。虽然粮食系统的首要目标是提供粮食安全,但近年来粮食不安全率持续上升。为了解决这些系统性问题,粮食系统专家呼吁开展粮食系统扫盲。然而,目前还没有一个共同的框架来概括人们应该了解粮食系统的哪些知识,这使得将信息传递到教育和普通民众中具有挑战性。因此,本研究的目的是确定加拿大青少年的粮食系统扫盲能力。我们进行了两轮修改后的德尔菲研究,以就粮食系统扫盲的关键能力清单达成共识。德尔菲研究可以广泛征求专家意见,就复杂问题达成共识。最终,在土著粮食系统、粮食系统活动(即从生产到浪费以及一些总体和技术主题)、可持续性、粮食安全和治理等主题中,制定了一份粮食系统素养的 50 项关键能力清单(共测试了 131 项)。该能力框架是首个此类框架,将有助于指导如何将粮食系统纳入教育,并为粮食系统素养评估工具提供指导。

Market food environments and child nutrition 市场食品环境与儿童营养
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-07 DOI: 10.1016/j.foodpol.2024.102704

Child malnutrition remains a widespread public health problem in sub-Saharan Africa. Providing access to nutritious foods for all is key, but it is not clear how this can be achieved in various local contexts. Here, we analyze the role of markets and food environments for child diets and nutrition in Malawi along a rural-urban continuum. We develop a new methodology to characterize food environments in terms of the variety of fresh and processed foods available in local market settings. Geocoded data of market food variety are combined with individual-level child diet and anthropometric data collected through a household survey.

儿童营养不良仍然是撒哈拉以南非洲地区普遍存在的公共卫生问题。为所有人提供营养食品是关键所在,但如何在不同的地方环境中实现这一目标却并不清楚。在此,我们分析了市场和食品环境对马拉维城乡儿童饮食和营养的影响。我们开发了一种新方法,根据当地市场上新鲜食品和加工食品的种类来描述食品环境的特征。市场食品种类的地理编码数据与通过家庭调查收集的个人层面的儿童饮食和人体测量数据相结合。我们发现,城市、农村和偏远地区的食品环境、饮食和营养结果存在很大差异。空间显性分析表明,市场食品种类与膳食多样性呈正相关,而与发育迟缓呈负相关,在控制了混杂因素后也是如此。引人注目的是,与新鲜食品种类相比,加工食品种类与儿童营养的关系更为有利,这表明在当地环境中,轻度和中度加工食品是重要的营养来源。我们的研究结果强调了改善营养食品市场功能的重要性,尤其是在农村地区。从概念上讲,我们为有关食品环境测量的文献增添了新的内容。

Impact of food hubs on food security and sustainability: Food hubs perspectives from Leeds, UK 粮食中心对粮食安全和可持续性的影响:英国利兹的粮食中心视角
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-05 DOI: 10.1016/j.foodpol.2024.102705

In the context of rising food insecurity, food hubs such as food pantries, food banks, community agriculture supported schemes, social supermarkets, community kitchens and cafes, have proliferated both in number and in the roles they perform. Food hubs have a range of benefits in the communities that they serve as well as the wider food system. However, more empirical evidence is required to build a compelling case for policy support. Using the area of Leeds, UK as a case study, and taking a mixed methods approach (i.e. evidence synthesis, mapping, survey and interviews) we present the food hubs’ perspectives on the benefits that they offer to food security, sustainability, resilience and food justice. Food hubs reflect on how their activities enhance sustainability, strengthen local food systems, support local economies, and improve the health, wellbeing and agency of their communities. In doing so, food hubs contribute to regional, national and global priorities on food security, health, sustainability, justice and resilience. However, to scale up or out their positive impact, food hubs require support to transition away from emergency food provision to longer-term, holistic and financially viable models that focus on community wellbeing and empowerment, healthy diets, local economies and environmental sustainability.

在粮食不安全问题日益严重的背景下,食品储藏室、食品银行、社区农业支持计划、社会超市、社区厨房和咖啡馆等食品中心的数量和作用都在激增。食品中心对其服务的社区以及更广泛的食品系统都有一系列好处。然而,需要更多的经验证据来为政策支持提供令人信服的理由。以英国利兹地区为案例,采用混合方法(即证据综合、绘图、调查和访谈),我们介绍了粮食中心对粮食安全、可持续性、复原力和粮食公正所带来益处的看法。粮食中心反思了它们的活动如何提高可持续性、加强地方粮食系统、支持地方经济以及改善社区的健康、福祉和能动性。在此过程中,粮食中心为地区、国家和全球在粮食安全、健康、可持续性、正义和复原力方面的优先事项做出了贡献。然而,为了扩大其积极影响,粮食中心需要得到支持,以便从紧急粮食供应过渡到长期、全面和财政上可行的模式,重点关注社区福祉和赋权、健康饮食、地方经济和环境可持续性。

Animal disease outbreaks and upstream soybean trade 动物疫病爆发与上游大豆贸易
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-01 DOI: 10.1016/j.foodpol.2024.102685

Animal disease outbreaks have been extremely disruptive to global livestock industries in recent years. In light of the modern integration of international supply chains, to what extent have these disruptions been experienced by upstream stakeholders? This research investigates the upstream impacts of global animal disease outbreaks in the international soybean market. We employ a two-step procedure to deduce the impacts of animal disease on upstream soybean trade. We first use a standard, econometric gravity model to empirically estimate the relationship between observed trade and livestock production patterns (accounting for each country’s economic masses and trade frictions). We then conduct a counterfactual analysis with our estimated gravity relationships to assess the value of lost soybean trade using a global repository of disease-specific animal mortality data. Our results indicate that between 2005–2020, animal disease outbreaks have cost the international soybean market approximately $5 billion in lost trade. The average exporter loses as much as 2% of its export potential each year. These losses are primarily attributable to cattle disease outbreaks in East Asia and South America. Foot-and-mouth disease alone has cost the soybean trade market approximately $4 billion in lost trade over our sample period.

近年来,动物疾病的爆发对全球畜牧业造成了极大的破坏。鉴于国际供应链的现代化整合,上游利益相关者在多大程度上受到了这些干扰?本研究调查了全球动物疫情爆发对国际大豆市场上游的影响。我们采用两步程序来推断动物疫病对上游大豆贸易的影响。首先,我们使用标准的计量经济学引力模型,对观察到的贸易与牲畜生产模式之间的关系进行实证估算(考虑到各国的经济总量和贸易摩擦)。然后,我们利用估算出的引力关系进行反事实分析,使用全球特定疾病动物死亡率数据来评估大豆贸易损失的价值。我们的分析结果表明,2005-2020 年间,动物疫病爆发给国际大豆市场造成了约 50 亿美元的贸易损失。平均每个出口国每年损失高达 2% 的出口潜力。这些损失主要归因于东亚和南美爆发的牛病。在我们的抽样调查期内,仅口蹄疫一项就给大豆贸易市场造成了约 40 亿美元的贸易损失。

Robust policy frameworks for strengthening the resilience and sustainability of agri-food global value chains 加强农业食品全球价值链的复原力和可持续性的有力政策框架
IF 6.8 1区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2024-08-01 DOI: 10.1016/j.foodpol.2024.102714

Agri-food global value chains (GVCs) have transformed food production and trade, fostering efficiency and specialization across international borders and also introducing new challenges. This paper synthesizes insights from a special issue focused on agri-food GVCs, addressing four critical areas essential for enhancing the resilience and sustainability of these chains. We explore how trade connections and specialization can drive economic growth, emphasizing the importance of GVC integration. We also examine the role of transportation and infrastructure in ensuring global trade efficiency, highlighting the need for strategic investments to support robust supply chains. Additionally, we assess the impact of trade policies on sustainability, market disruptions, and overall efficiency, underscoring the importance of regulatory frameworks that promote both economic and environmental goals. Finally, we consider the implications of domestic and trade policies on welfare and equity, particularly in developing regions where inclusive growth remains a pressing concern. By identifying these essential areas for robust policy frameworks, this paper provides actionable insights for enhancing the resilience and sustainability of the global food system, which can inform policies that enhance the benefits of agri-food GVC integration while mitigating their risks.

农业食品全球价值链(GVCs)改变了粮食生产和贸易,提高了效率,促进了国际间的专业化分工,同时也带来了新的挑战。本文综述了以农业食品全球价值链为重点的特刊中的观点,探讨了对提高这些价值链的复原力和可持续性至关重要的四个关键领域。我们探讨了贸易联系和专业化如何推动经济增长,强调了全球价值链一体化的重要性。我们还探讨了运输和基础设施在确保全球贸易效率方面的作用,强调了进行战略投资以支持强大供应链的必要性。此外,我们还评估了贸易政策对可持续性、市场混乱和整体效率的影响,强调了同时促进经济和环境目标的监管框架的重要性。最后,我们考虑了国内和贸易政策对福利和公平的影响,尤其是在发展中地区,因为这些地区的包容性增长仍然是一个紧迫问题。通过确定健全政策框架的这些重要领域,本文为增强全球粮食系统的复原力和可持续性提供了可操作的见解,这些见解可为制定政策提供参考,从而提高农业-食品全球价值链一体化的效益,同时降低其风险。
