Seasonal changes in food availability and disease incidence put pressure on children’s health in Sub-Sahara Africa. Using year-round survey data from Senegal, we examine how seasonality in key health inputs (dietary diversity, diarrhea, and fever) helps predict seasonality in children’s health (weight-for-height z-score). We first parameterize seasonal variation in health and health inputs using second-order trigonometric polynomials, then decompose the seasonal curve of children’s health into component parts explained by seasonality in each health input. We find that lagged seasonality in disease incidence predicts seasonality in child health, while seasonality in dietary diversity does not — likely because diets are poor in Senegal even during the most food-plentiful part of the year. We also observe noticeable heterogeneity in the way these health inputs predict children’s health across different wealth levels and regions.
食物供应和疾病发生率的季节性变化给撒哈拉以南非洲地区的儿童健康带来了压力。利用塞内加尔的全年调查数据，我们研究了主要健康投入（饮食多样性、腹泻和发烧）的季节性如何帮助预测儿童健康的季节性（体重身高 Z 值）。我们首先使用二阶三角多项式对健康和健康投入的季节性变化进行参数化，然后将儿童健康的季节性曲线分解为由各健康投入的季节性所解释的组成部分。我们发现，疾病发病率的滞后季节性可以预测儿童健康的季节性，而饮食多样性的季节性却不能预测儿童健康的季节性--这可能是因为塞内加尔即使在一年中食物最丰富的时期，饮食也很贫乏。我们还观察到，在不同的财富水平和地区，这些健康投入对儿童健康的预测方式存在明显的异质性。

In most low-income countries, households are exposed to a plethora of economic shocks with welfare-reducing consequences. In the absence of well-functioning financial markets, most households rely on informal savings through credit clubs/groups to reduce their vulnerability to these shocks. In this paper, we examine the extent to which participation in informal savings associations affects the ability of households to smooth their consumption in the face of both idiosyncratic and covariate shocks. Using a difference-in-difference fixed effects specification on the Nigerian household-level panel that spans four waves over eight years, with data collected in 2010/2011, 2012/2013, 2015/2016 and 2018/2019, we documented heterogenous effects of informal savings. The results suggest that informal savings help households to hedge consumption against rainfall shocks. We find heterogeneous effects of informal savings in insuring consumption against idiosyncratic shocks, depending on whether households live in urban or rural areas. These results provide new insights into the role of informal financial arrangements in sub-Saharan Africa.

Nutrition Facts labels or Nutrition Facts Panel(s) (NFP) are a critical channel for communicating food nutrition information to consumers. A fundamental question is how to help consumers effectively understand and use the label without missing important information. This paper introduces a color-coded NFP and investigates its impacts on information search and consumer behavior, such as attention to information, food choice, and food health perception. Results show that the color-coded NFP attracts more attention than a black-and-white NFP, specifically for nutrients such as fat, sodium, and sugars, which should be limited. Additionally, the color-coded NFP made it easier for consumers to make food purchase decisions and led consumers to make healthier choices for some products (e.g., chips). Finally, the color-coded NFP reduces the time needed and contributes to a more accurate evaluation of the products’ healthiness in the case of chips, reducing the information processing costs and increasing the utilization of information. Our research demonstrates that the color-coded NFP is more attractive, efficient, and effective in delivering nutrition information and contributes to a healthier decision for some products (e.g., chips) than the traditional NFP.

Food policy integration is critical for sustainability as urban food policies become a new norm in the policy agenda. Yet, little research demonstrates how food policies are integrated with food systems and across governance to achieve urban sustainability. This paper presents the Trans-Governance and Food Systems (Tr-GaF) framework for food policy integration developed to evaluate the Australian food policy landscape. The analysis of 102 food-relevant policy documents sourced from multiple government institutions in Queensland, Western Australia, and Victoria identifies limited food policy integration in Australia, with little attention paid to food-related urban planning. Policy misalignments arise in the agrifood economy, health and well-being, and environment and ecology domains, with horizontal and vertical fragmentation across governance levels and sectors. Inadequate integration with food systems further jeopardises the efficiency of urban food supply chains and consumption activities. These three prominent issues collectively stifle urban sustainability by economically restraining food supply chain actors’ ability to innovate and compete. While environmental imbalance worsens, urbanites inevitably face barriers to maintaining health and social well-being. Tr-GaF provides an evidenced-based framework for policymakers to evaluate and integrate food policies anchored in food systems governed by collaborative multi-scalar government agencies, institutions, food industries, and civil society. In doing so, urban development can sustainably evolve economically, socially, and environmentally.

Debates on the role of farm size for farm productivity and economic development are longstanding in agricultural and development economics. However, the link between farm size and achieving decent work and full employment—Sustainable Development Goal 8—remains unexplored, despite many African countries facing huge unemployment challenges alongside important changes in farm sizes. This paper addresses this gap by focusing on Nigeria’s labor-intensive tomato sector and using unique primary data from a matched farm-to-worker survey. We analyze the relationship between farm size and both the quantity and quality of jobs, which has never been studied before, employing multivariate regression analysis. Additionally, we account for factors that commonly differentiate larger and smaller farms, including technology use, market arrangement, crop diversification, and the reliance on seasonal versus casual labor. Our findings reveal a trade-off: smaller farms offer more jobs per hectare, while larger farms offer better jobs (i.e., higher wages and some non-monetary benefits). We conclude that neither larger nor smaller farms fully align with all dimensions of decent work and full employment, highlighting the need for greater policy and research focus on the employment quality versus quantity dilemma.

Malnutrition remains a serious problem. While various nutrition policies exist, these often fail to consider cultural factors. We contribute to the literature on culture and nutrition, focusing on gendered differences in nutritional investment. Using representative panel data from Indonesia covering a period of 21 years, we analyze how ethnicity-based marriage customs are linked to the body mass index (BMI) of men and women. Patrilocal practices are positively associated with male BMI and negatively associated with female BMI, suggesting discrimination against women. Matrilocal practices are positively associated with female BMI when comparing with women in other cultural settings, but not when comparing with men. The practice of bridewealth is positively associated with male and female BMI when comparing to individuals in settings without this cultural practice. Wherever positive associations between marriage customs and BMI are observed, these are largest for those already overweight, whereas the negative association been patrilocality and female BMI is most pronounced among women who are underweight. Our findings suggest that marriage customs may reinforce nutritional inequalities. A better understanding of such links in different cultural settings is important for effective nutritional policies, especially given that different malnutrition problems coexist in many countries.

The escalating effects of climate change make it important to find ways to offset the carbon burden. One way to do so is to reduce beef consumption, since cattle production creates large amounts of greenhouse gases, which contribute to global warming and climate change. In this study, we explore US consumers’ perceptions of alternative beef products. Specifically, we test the effects of three types of earmark information on consumers’ valuation of a beef carbon tax related to hamburger meat through two labeled discrete choice experiments. Our results show that earmark information can be effective in reducing the negative impact of an environmental tax on consumers’ willingness to pay for beef products. This study contributes to a better understanding of how consumers would bear environmental taxes for beef and alternative products.

In many low- and middle-income countries, agri-food supply chains are transforming rapidly. One important feature of this transformation is growth in certain high-value agricultural subsectors, such as horticulture and cut-flowers for export. Growth in high-value agriculture often creates new employment opportunities, especially for women. More employment can lead to higher rural incomes, but the broader implications for social welfare are not yet sufficiently understood. Here, we use survey data from Ethiopia to investigate the effects of women’s employment in floriculture on child nutrition, focusing on children aged 0–5 years. We develop and estimate endogenous switching regressions to account for possible endogeneity. Our results suggest that maternal employment in floriculture negatively affects child height-for-age and weight-for-age z-scores (HAZ and WAZ). Exploration of the underlying mechanisms reveals that floriculture employment may influence time allocation, dietary quality, income, and female financial autonomy. Maternal employment is negatively associated with time spent on childcare and consumption of animal-sourced foods.

This study explores the impact of providing general health-related information and personalized nudges aimed at modifying cognitive biases on enhancing vegetable purchases and consumption. We conducted a four-month natural field experiment and analyzed daily purchase records of 942 households using receipt scanner data. While merely explaining the loss-framed health benefits of vegetables did not significantly alter the overall vegetable purchasing habits, we observed a notable decrease in meat purchases, attributing this to the indirect effects of vegetable information. Additionally, when the status of relative vegetable purchases amount was provided based on personal purchase histories, individuals who initially purchased more vegetables demonstrated an increased buying volume. This effect was more pronounced in households with children than in those without. The nudging interventions had long-term effects beyond the experiment’s duration, possibly driven by an altruistic concern for children’s health within the household. Therefore, while nudges alone are not a complete solution, their ability to effect long-term changes in household purchasing patterns suggests that they can be a valuable addition to policy tools promoting sustainable and healthy food choices, as well as traditional mass-targeted promotion strategies.
