However, concerns are mounting about the low and decreasing yield response and profitability of inorganic fertilizer use, particularly in Sub-Saharan Africa. This study aims to refine yield response and profitability models by incorporating recent data from nationally representative and panel datasets spanning six countries. Most countries exhibited low nitrogen yield responsiveness (4–7 kg), while Ghana and Uganda showed higher responsiveness (15–20 kg) per additional 1 kg of nitrogen. Analysis of fertilizer-to-maize price ratios from 2010 to 2023 showed a downward trend, with spikes in 2022 in Ghana, Malawi, Nigeria, and Tanzania. Overall, except for those years, the data suggest a trend of increasingly favorable price incentives for fertilizer use. Ethiopia, Tanzania, and Uganda experienced declines in the fertilizer-to-maize price ratio. Increasing inorganic fertilizer use would be profitable in Ethiopia, Ghana, Nigeria, and Uganda at current market prices, but not in Malawi or Tanzania. Subsidies in Malawi and Tanzania have boosted profitability, but these may not be necessary in Ghana, Nigeria, or Uganda, which already have favorable price incentives; Malawi could benefit by substantially reducing its 80 percent subsidy while maintaining decent price incentives and farm profits. The paper proposes policy options based on factors influencing yield responsiveness and potential improvements drawn from new modeling and synthesis of the literature.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"133 ","pages":"Article 102815"},"PeriodicalIF":6.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099368","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}

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.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"133 ","pages":"Article 102792"},"PeriodicalIF":6.8,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099419","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}

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<sup>th</sup> percentile to USD 2,900 at the 95<sup>th</sup> 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.

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.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"130 ","pages":"Article 102791"},"PeriodicalIF":6.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094597","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 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.
