Such interventions include biofortification, an important nutrition-sensitive agricultural approach that can sustainably improve food and nutrition security among vulnerable populations. However, there is limited evidence of success and lessons for scaling this approach. Using a sample of 636 households drawn from three arid and semi-arid counties in Kenya, this study uses a doubly robust estimator and non-parametric methods to investigate the effect of promoting vitamin-A-biofortified sweet potato as a nutrition-sensitive, climate-smart agricultural intervention to improve nutritional outcomes in humanitarian settings. We find that interventions combining demand-creation strategies and access to biofortified planting material significantly enhance nutrition knowledge and household nutrition indicators such as dietary diversity and food security. Individual interventions that either create demand or provide access to planting material enhance nutrition awareness but do not lead to primary nutrition outcomes such as dietary diversity. Lastly, enhancing access to planting material leads to higher nutritional outcomes compared to demand-creation strategies carried out in isolation.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"132 ","pages":"Article 102834"},"PeriodicalIF":6.8,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577297","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}

This study investigates the key drivers of urea prices in China—the world’s largest producer and a major exporter. First, we analyze price transmission between China’s domestic spot and export urea markets, finding no cointegration even prior to the export restrictions introduced in October 2021. Next, we employ a structural vector autoregression model to examine domestic urea price spikes, using a heteroskedasticity-based identification strategy that allows for smoothly transitioning covariances. We decompose urea prices into four structural shocks: supply shocks driven by energy price changes, demand shocks linked to crop price fluctuations, export demand shocks, and market-specific idiosyncratic shocks unrelated to the first three. The findings reveal that rising energy costs and idiosyncratic factors were the main drivers of urea prices in China from 2018 to 2023, while shocks to corn prices and export demand had a smaller impact. Overall, the results indicate that recent export restrictions have had limited influence on domestic urea prices, calling into question the effectiveness of China’s October 2021 export restrictions as a price stabilization measure.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"133 ","pages":"Article 102829"},"PeriodicalIF":6.8,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512200","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 study, we examined how prioritizing domestic fish consumption in some net-exporting countries with low fish consumption could improve fish availability and impact global and regional health burdens. Using bilateral fish trade data from 2010 to 2019 and diet-disease relationships, we compared the impact of current trade versus trade patterns (focused on domestic consumption) on reducing deaths from ischemic heart disease (IHD), the world’s leading cause of death. Our results showed that the current trade system delivered health benefits and could have prevented approximately 130,000 IHD deaths worldwide; one-third of these benefits went to high-income countries, where health gains were mainly transferred from net-exporting low- and middle-income countries (LMICs) with relatively high IHD death rates. Shifting a portion of exports to prioritize domestic consumption in net-exporting countries may reduce IHD deaths by 26% in LMICs and prevent an additional 15,400 IHD deaths globally compared with the current trade. Moreover, it would only cause a 0.7% reduction in health benefits in net-importing countries and no reduction in low- and lower-middle-income net-importing countries. Thus, increasing fish consumption in countries with low fish intake could be more effective in reducing the global burden of disease.
