This research integrates choice experiments evaluating five potential attribute improvements (two quality levels, safety/hygiene, pre-cutting and lower acquisition time costs) with participatory value-chain modeling to evaluate the potential impact of these attribute improvements on spinach consumption in Kenya. Choice experiment data from 300 households in six counties of Kenya, analyzed with random parameter logit and panel Tobit models indicates quality, safety and hygiene, and acquisition time affect purchase probabilities and expected purchase quantity, but the effect of increased convenience is lower. Analyses with a dynamic value-chain model including farmers, marketing intermediaries, vendors and consumers indicate that all of the attribute improvements would increase consumption even in light of higher value-chain costs, but also facilitate larger sales and profits by value chain actors. These results suggest that a focus on increasing demand through the improvement of product attributes may be an important strategy for simultaneously increasing fruit and vegetable consumption and benefitting value chain participants in low- and middle-income country settings.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"127 ","pages":"Article 102682"},"PeriodicalIF":6.8,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141950353","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}

Parallel to this trend, many LMICs are witnessing significant growth in their participation in global food value chains (GFVCs). This paper aims to shed light on the public health implications of increasing participation in GFVCs. Leveraging macro- and micro-level data spanning 25 years, we study the relationship between countries’ participation in GFVCs and women’s overweight or obesity rates. We explore heterogeneous implications by disaggregating countries’ participation into backward and forward linkages in GFVCs, as well as across rural and urban areas. We find that temporal increases in countries’ participation in GFVCs are significantly associated with increasing overweight or obesity rates, primarily when countries participate in backward linkages and for urban populations. Participation in GFVCs involving forward linkages appears to have negligible implications, and the relationship between participation in GFVCs and obesity disappears for rural women. Furthermore, we find that an increase in countries’ participation in GFVCs is associated with an increase in consumption of energy-dense foods such as sugar, commonly linked with obesity. Our findings have important implications for informing public policies aimed at addressing the increasing obesity rates and associated economic and health burdens in LMICs.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"127 ","pages":"Article 102710"},"PeriodicalIF":6.8,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142077362","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}

The study highlights that higher temperatures are associated with a modest yet statistically significant decrease in the dietary diversity of children aged 6 to 23 months. We also find that, while minor temperature variations may have minimal effects, larger shifts within specific temperature ranges can lead to more pronounced alterations in children’s dietary diversity. Moreover, factors such as children’s age, historical climate context, and seasonality influence the magnitude of this relationship. Additionally, access to infrastructure and maternal education significantly mediate the adverse effects of temperature on children’s dietary patterns, highlighting the importance of targeted interventions in vulnerable communities..</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"128 ","pages":"Article 102703"},"PeriodicalIF":6.8,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0306919224001143/pdfft?md5=53e9eb913848781b55ff314b20eed947&pid=1-s2.0-S0306919224001143-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141938320","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}

The analysis is based on survey data from okra production in India and controls for unobserved heterogeneity between farmer villages, a novel procedure that circumvents the problem of multicollinearity between the treatment variable and village fixed effects. Findings indicate that monopsonist production contractors depress farm gate prices below the level of oligopsonist marketing contractors.

A subsequent scenario simulation quantifies the potential income gains for farmers if contractors’ market power could be reduced, finding that the incomes of production contract farmers could increase by one-fourth in the absence of market power.

As countries increasingly participate in global agrifood value chains (GAVC), their significance becomes even more pronounced. We highlight stylized facts, evolution, trends, and key players of GAVCs integration between 1990 and 2020 using data from the rich EORA multi-region input–output tables. Following this, we examine the relationship between GAVCs and dietary energy consumption, prevalence of undernourishment, overweight and stunting in low and middle income countries. Employing the Bartik shift share instrumental variable approach and several other identification strategies, we show a positive (negative) association between countries’ participation in GAVCs and dietary energy consumption (prevalence of undernourishment). We underscore substantial heterogeneity by income groups. Generally, results for countries in the upper-middle-income group are consistent with those of the global sample. However, GAVC participation of low-income countries is associated with reduced stunting only, and mixed results are found for lower-middle-income countries, including reduced stunting alongside increased undernourishment and overweight. These findings suggest that integration in global value chains could be conducive for food security and nutrition on the global level and the majority of country income groups, however contextual differences remain. Thus, policies targeting global value chain integration, food security and nutrition should be designed on a country-by-country basis and well-tailored to the specific challenges faced.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"127 ","pages":"Article 102679"},"PeriodicalIF":6.8,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141960050","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}

In this context, a tax on meat products is frequently proposed as a policy measure to stimulate a dietary shift away from meat products. Understanding public preferences for the design of such a tax may serve as a starting point for increasing its political feasibility. Our paper explores public preferences for meat tax attributes among inhabitants of the Netherlands, the most livestock-intensive country in Europe. Using a discrete choice experiment, we estimate relative preferences for the following tax design attributes: (i) use of tax revenues; (ii) products under taxation; and (iii) joint efforts by other countries. Our results indicate that Dutch people significantly prefer a meat tax that exempts poultry or organic products, is implemented in a joint effort with several other EU countries, and earmarks revenues for specific purposes, with the preference for using revenues to reduce the value-added tax on fruits and vegetables being the strongest. We find significant heterogeneity in these preferences, which we explore using a latent class logit model. While the classes do not exhibit highly distinct socio-economic profiles, they are characterized by a combination of factors such as gender, income levels, and education. Our results may inform ongoing discussions about meat taxation in the Netherlands and contribute to further research on meat tax preferences in other countries.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"128 ","pages":"Article 102675"},"PeriodicalIF":6.8,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0306919224000861/pdfft?md5=383b0390cd6de3eef9746169fb13b7b6&pid=1-s2.0-S0306919224000861-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141950067","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}
