Data analysis leverages the sequential nature of the rounds, experimental treatments, and a wine knowledge questionnaire to investigate the hierarchical structure and level of redundancy between alternative information sources, the role played by wine prices, and previously acquired expertise. We estimate that the average value of accessing GI information in a pre-purchase scenario lies between EUR 0.33 (Spain) and EUR 0.37 (France) for each purchasing occasion, and expert reviews provide a similar level of information. These findings are consistent across different price segments (high: €13-€17 vs. low: €4-€7). Firm names have lower average valuation but are more useful to high-knowledge consumers. GIs, firm names, and expert reviews are found to be imperfect substitutes, suggesting that GIs capture elements of both horizontal and vertical differentiation. The discussion is structured along three main thematic areas of contribution: the role of GIs as signals of quality, the extant literature studying how consumers interpret quality signals, and the contrast between our findings and the modeling assumption adopted in the GI theoretical literature.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"130 ","pages":"Article 102769"},"PeriodicalIF":6.8,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated consumer preferences for low-methane ground beef produced using one of three MRAs with varying levels of methane mitigation: <em>Aspagopsis taxiformis</em> (seaweed), the organic compound <em>3-nitroxypropanol</em> (3NOP), or a blend of essential oils (e.g. garlic extract and citrus). In a nationally representative survey, 3,009 respondents completed a labeled discrete choice experiment used to estimate preferences, WTP, and market shares for conventional and low-methane ground beef. Randomized groups were given pre-purchase information about methane emissions from beef production and point-of-purchase labels communicating the methane reduction levels for each MRA. Given the contemporaneous rise in beef prices, respondents were randomized between a low and high-price group to examine the sensitivity of results. While conventional ground beef was generally preferred, consumer WTP and average market shares for the seaweed MRA product (the MRA with the highest methane reduction potential) surpassed conventional beef for the group that received pre-purchase and point-of-purchase information.

By analysing data collected through interviews with participants working on initiatives spanning 13 cities across 9 European countries, we identify the manifestation of six propelling mechanisms that signal the capacity of small wins to bring about systemic change. Findings from this study reveal the presence of most mechanisms across the included initiatives. However, the ways in which these mechanisms appear depend on various factors such as stakeholder motivation, the maturity of the initiative, the need for additional funding, local food culture, and the regional and national political landscape among others. Our analysis indicates that the Small Wins Framework could be successfully used as a mapping tool in urban transformation processes, but it is likely to be more effective as a tool for reflexive monitoring rather than ex-post evaluation. Drawing on the impacts of various large-scale disruptions on the initiatives, we suggest that social, political, and economic shocks can present windows of opportunity to accelerate change and that initiatives performing well under such pressure should be supported in their pursuit of systems transformation. Lastly, we recommend non-linear growth strategies such as spreading, deepening, and expanding, as ways to compound the impact of small wins.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"129 ","pages":"Article 102761"},"PeriodicalIF":6.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142593156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, if water stress occurs, we found that its timing determines which seed variety performs best. If water stress conditions are confined to the late season, early-maturing varieties escape drought and perform better than medium- and late-maturing varieties. Instead, if water stress conditions start already from mid-season, early-maturing varieties perform worst.

Promoting food conservation behaviors among residents is crucial; however, there is little evidence of the consumer-related driving factors behind this behavior from both internal and external perspectives. Based on the theory of planned behavior and the structural equation model, this paper examines the impact mechanism of internal moral constraints and external government intervention on the psychology of saving food among Chinese urban residents in one research framework. Survey data combined from random street-stop interviews and an online survey are applied. Results show that moral constraints, as internal factors, still play a crucial role in forming Chinese urban residents’ willingness to save food. The most influencing mechanisms are through impacts on attitude (personal moral cognition) (β = 0.311) and perceived behavioral control (comparison of economic and moral costs and benefits) (β = 0.581). In the meantime, government interventions, as external factors, significantly impact residents’ willingness and behavior to save food. The government’s efforts in guiding food conservation have a direct promoting effect (β = 0.135) on the respondents’ food-saving willingness, while services and support to food conservation from the government directly promote food-saving behaviors (β = 0.068). Also, the number of household generations and respondent age positively impact food saving willingness, while chronic diseases, income, and food consumption expenditure have adverse impacts. Policies encouraging food saving need to conduct from both internal and external intervention. On the one hand, it demands to strengthen residents’ moral constrains by promoting traditional virtues and improving the awareness of global food security challenges, which can increase the benefits of food saving behaviors in terms of moral values. On the other hand, government intervention on guiding and supporting food conservation can effectively increase both willingness and behaviors of food saving.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"129 ","pages":"Article 102767"},"PeriodicalIF":6.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142659403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, there is no consensus on how empowerment should be measured. The surrounding debate has produced several empowerment metrics that are widely used, yet we know little about whether they can be substituted for one another or their respective strengths and weaknesses. Using data collected from a single sample of women from rural, northern Kenya, we compare five empowerment metrics: The Project-level Women’s Empowerment in Agriculture Index (pro-WEAI) and associated Health and Nutrition Module (HN), Women’s Empowerment in Nutrition Index (WENI), Women’s Empowerment in Livestock Index (WELI), and the Survey Based Women’s Empowerment Index (SWPER). The metrics have shared theoretical origins and are commonly used in the food, nutrition and health spaces to study rural women’s lives across low- and middle-income countries. We examine the metrics’ characteristics, distributions, pairwise correlations and capacity of each metric to predict outcomes often associated with the concept of empowerment: body mass index (BMI) and the Center for Epidemiologic Studies Depression Scale (CES-D). We find striking differences between these common empowerment metrics. The metrics’ correlations with one another are highly variable as are the predictive capacities for both outcomes. Further, our analysis finds that the choice of metric can dramatically influence which individuals are identified as empowered. In sum, our results suggest that while these metrics are used in remarkably similar ways to understand rural women’s empowerment and its consequences, unless they are computed with many identical survey questions, the metrics do not capture the same underlying concept and are not interchangeable. We recommend that our work be replicated elsewhere and caution should be taken when implementing and interpreting research using these metrics, as findings may be highly sensitive to the choice of metric.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"129 ","pages":"Article 102764"},"PeriodicalIF":6.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142659404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now widely recognized that the combined use of improved seeds and inorganic fertilizers – which were critical to the Asian Green Revolution – are necessary but insufficient conditions for African farmers to sustainably raise the productivity of their cereal crops. We highlight three key conclusions emerging from the VSC. First, achieving a maize SGR in sub-Saharan Africa (SSA) will require the development of site-specific soil management practices that can be consistently applied by highly resource-constrained farmers. This condition is far from being achieved in most of SSA. Second, the challenges to achieving a rice SGR are different: Best management practices are largely established and effective. Rice yields have already increased dramatically in parts of SSA where Asian-style seed-fertilizer technology and cultivation practices have been adopted. Therefore, the priority for enhancing rice productivity in SSA is to promote wider adoption of these established practices in rice-producing areas. Third, overcoming these challenges for both maize and rice requires strong adaptive agricultural research, development, and extension organizations on the ground. Many African countries currently lack these organizations to carry out the core activities required to achieve a SGR; therefore, building institutional capacity for national and regional agricultural research, extension, and policy analysis is a fundamental component of an effective SGR strategy.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"129 ","pages":"Article 102762"},"PeriodicalIF":6.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142560536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates both consumers’ and farmers’ preferences for different SFSC outlets. Harmonized discrete choice experiments (DCEs) were conducted in 2022 in France, involving 1,021 consumers and 154 market gardeners, focusing on the consumption and sale of fresh vegetables. The objective is to examine the consistency and divergence between farmers’ and consumers’ choices among different outlets and attributes. The results indicate that consumers are less sensitive to the type of outlet than farmers. For consumers, relational proximity—direct interaction with farmers—emerges as a key factor, whereas farmers value this proximity only when it does not entail additional logistical burdens. Furthermore, mutual aid among farmers is highly appreciated, with farmers willing to lower prices when collaborating on tasks such as delivery. The findings suggest that travel time and outlet accessibility are critical, with longer travel times negatively affecting consumers more than farmers. These insights provide valuable guidance for enhancing SFSCs development, suggesting that policymakers should prioritize improving outlet accessibility, promoting farmer collaboration, and addressing logistical costs to better align supply with demand.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"129 ","pages":"Article 102763"},"PeriodicalIF":6.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
