Community Seed Banks (CSBs) are promoted as an approach to support farmers’ access to quality seeds of adapted varieties. While the adoption and impact of varieties distributed through conventional formal seed systems have been extensively studied, research on how participation in CSBs relates to farmers’ seed systems and food security is limited. This paper uses survey data covering 688 households and 1600 plots from Northern and Central Malawi, combined with historical climate data, to assess the extent to which farmers are utilizing CSBs as a seed source and the association of farmer participation in CSBs with a range of other foods system variables. We find that CSBs are the source of about 1/3 of the seeds of maize, groundnut, and soyabean used by the participants and that they source less of their seeds from their own harvest compared to non-participants. While the use of CSB seeds of different crops shows mixed associations with yields at the plot-level, we find that CSB participation is positively associated with higher household food security overall. Furthermore, we find a positive association between exposure to high mean temperatures and rainfall shortages and the propensity to participate in CSBs, suggesting CSBs play a role in adaptation. This study thus shows that CSB participation is associated with several positive food system outcomes, but more research is needed to understand the causal links as well as the efficiency of CSBs compared to other approaches to strengthen farmers’ seed security.

This study examines the impact of early growing season temperature variation on fertilizer use among maize-producing smallholder farmers in Ethiopia. A unique, decade-long dataset collected at the plot level was integrated with climate data to construct weather variation indicators that are comparable across time and space. The findings reveal that smallholder farmers adapt their fertilizer application strategies in response to early growing season temperature variations. Heterogeneity analyses show that environmental factors such as altitude affect fertilizer use when farmers face early growing season temperature variations.

The drive to mechanize and modernize African agriculture is in high gear, making the need for empirical evidence to guide mechanization investments critical. This paper assesses the heterogenous and distributional correlates of using mechanization and rural livelihoods in Chegutu and Zvimba districts of Zimbabwe, where a private sector company had the largest sales of different machinery across the country between 2019 and 2021. We used a quantile regression estimator and measured livelihoods using farm and household revenues. Based on survey data from 988 randomly selected households, we found that adoption was associated with rising land/labor ratio, market access and wealth. The use of mechanization was associated with a median annual increase of USD 262 in revenue with a wide range from USD 103 at the 25^th percentile to USD 2,900 at the 95^th percentile per year. The largest revenue gains were associated with post-harvest and irrigation equipment use, and in the upper percentiles of the revenue distribution. These findings call for (i) wealth agnostic promotional efforts to ensure equitable mechanization benefits, (ii) better targeting of mechanization types to farmer needs, and (iii) concerted efforts to strengthen mechanization service provision models.

The prevalence of sugar-sweetened beverages (SSBs) consumption is supposed to be one of the most important drivers of nutritional diseases, while little is known about whether sugar labeling could affect consumers’ preferences for low- or sugar-free beverages and what the role of nutritional cognition is in their consumption choice. Based on the data from the online survey and laboratory experiments, this study conducts a discrete choice experiment (DCE) to evaluate consumers’ willingness to pay (WTPs) for SSBs and examine to what extent nutritional cognition could affect their preferences. More importantly, we extend our analysis by incorporating consumers’ visual attention data based on eye-tracking technology into DCE to highlight the underlying physiological mechanisms of consumers’ choices. The results show that consumers exhibit various preferences and WTPs for different attributes of SSBs, including sugar content, functional category, and health claims. Consumers have higher preferences and WTPs for low-sugar and sugar-free beverages compared to SSBs, especially those with higher nutritional cognition who are more likely to choose sugar-free beverages. Evidence from eye-tracking technology suggests that consumers paying higher visual attention to the specific attribute considered are more likely to choose the products with that attribute, and individuals who exhibit higher nutritional cognition are more attentive to low-sugar and sugar-free attributes. This study suggests that consumers’ nutritional cognition and more prominent product design of sugar labeling should be considered in the promotion of low-sugar and sugar-free products.

We analyze how a potential CO₂eq-tax on the most emission-intensive agricultural goods in Germany affects CO₂eq-emissions and the income distribution.Based on data from the German survey of income and expenditure, we use a linear approximated Exact Affine Stone Index demand system to estimate own-price and cross-price elasticities for meat, dairy goods and eggs. These elasticities allow us to obtain demand changes and thus emission reductions following the introduction of a CO₂eq-weighted carbon tax based on the social cost of carbon. We find that it can reduce annual agricultural emissions in Germany by more than 15.3 MtCO₂eq or about 22.5%. The tax generates an annual revenue of more than 8.2 billion EUR. Since the carbon tax is regressive, we consider the distributional effects of a per capita lump-sum compensation scheme. We show that this “fee and dividend” approach has a slightly progressive effect on the distribution of income.

This study estimates the extent to which rural consumers in sub-Saharan Africa value quality signals about their food. We tested this by implementing an incentive-compatible Becker-Degroot Marschak auction among consumers in Niger and Northern Nigeria to estimate their willingness to pay (WTP) for cowpea (blackeyed pea) that was stored and sold in an improved grain storage bag that signaled unobservable quality in the form of insecticide-free grain. The improved bag had two inner layers of high-density plastic that created an airtight seal around the grain stored in it. The seal killed insects through suffocation rather than insecticide. The bag also had a branded label from its manufacturer on its outer layer to help distinguish it from a generic single-layer, woven storage bag. We estimated the size of the price differential (premium) that the average consumer placed on unobservable grain quality, as measured through the WTP premium for grain sold in the improved bag with a label. We also estimated the effect that consumers’ previous awareness of the improved bag had on their valuation of observable and unobservable quality. Our results indicated that on average consumers in Niger were willing to pay a 10% premium for cowpea stored and sold in the improved storage bag compared to cowpea of the same observable quality that was sold in a generic woven bag. The same unobservable quality premium was 17% in Nigeria. The results from this study provide evidence that there may be a latent demand for quality proxied by food safety among limited resource people in sub-Saharan Africa and that improved products with branded labels can potentially provide a quality signal to the market.

This article studies the attitudes of the public and politicians toward a tax on red and processed meat in Sweden, and how acceptability is affected by framing the tax as either: 1) a climate tax, 2) a public health tax, or 3) both a climate and public health tax, as well as specifying the use of tax revenues to a) support agriculture, b) support further climate [public health] initiatives, c) reduce VAT on broad categories of foods, or d) reduce VAT specifically on fruit and vegetables. These revenue uses were designed to isolate the impact of effectiveness, cost-neutrality and compensation of affected groups. Experimental survey-data were collected from 3,233 citizens and 1,253 politicians. The results showed that framing the tax had no effect on politicians and only a minor one on citizens; they became slightly more positive about the combined climate and public health justification compared to solely public health. The acceptability was generally greater when revenues were specified as opposed to unspecified, but the two cost-neutral revenue uses (a tax shift entailing either a broad reduction of VAT or just on fruit and vegetables) were the most acceptable proposals to both the public and politicians. The feasibility of implementing a tax on red and processed meat could be improved by ensuring that the average consumer’s total food costs do not increase and that any revenues are used to enhance the effectiveness of such a tax.

In the wake of the COVID-19 pandemic, rising food prices have become a defining feature of the global landscape. In high-income countries, rising food prices have been accompanied by record corporate profits, sparking allegations of “greedflation”. Policymakers around the world are investigating ways to curb rising food prices and build more sustainable food systems. Strikingly missing from this policy conversation is the role of diverse, local alternatives, like farmers’ markets in supporting more resilient food systems. This study investigates the inflationary dynamics within Canada’s local food systems compared to mainstream grocery retail. Employing a mixed methods approach, the research team analyzed price data from 223 farmers’ market vendors across Canada from 2018 to 2023 and conducted 17 semi-structured interviews with vendors. The exploratory findings reveal that most local food products experienced less inflation than those in mainstream grocery stores. The results underscore the need for policy frameworks that support local food systems to enhance food security and sustainability. The study contributes to the broader discourse on food price inflation and corporate concentration, offering insights that are relevant beyond the Canadian policy context.

The National Bioengineered Food Disclosure Standard in the United States mandates the disclosure of foods with bioengineered ingredients. However, some gene-edited foods are excluded from the Standard. This study explores consumer preferences and willingness to pay (WTP) for bioengineered and gene-edited foods, with a focus on romaine lettuce, in a multi-product specific design where they are compared to conventional, organic, and non-GMO alternatives. Our analysis includes three disclosure formats: the BE label, text, and QR code. We also determine the impact of information-seeking behavior on consumer valuations and the factors influencing such behaviors. Findings reveal a preference for conventional, organic, and non-GMO products over gene-edited and bioengineered options. However, the BE label is identified as the most favored disclosure method. In fact, under the BE disclosure, and particularly among information seekers, WTP for gene-edited and bioengineered products sometimes exceed WTP for conventional options. The study discusses policy implications regarding how disclosure formats and access to information can influence consumer perceptions and acceptance of new food technologies.
