When temperature and humidity increase above critical levels, dairy cows become heat-stressed and experience a drop in milk production. We quantify the impact of heat stress on the dairy industry throughout the Midwestern and Eastern United States in the years 2012–2016 using animal-level production data. We estimate that 1% of total annual yield is lost to heat stress, and losses are predicted to increase about 30% by 2050 on average under various climate scenarios. We provide three new insights compared to previous estimates with aggregated data. (1) Heat stress disproportionately affects milk quality, having larger impacts on farm income and nutritional value than previously estimated. (2) Small farms experience the largest losses to heat stress, suggesting they face barriers to adaptation. (3) Cows in the highest-yield production stage are the most vulnerable to heat stress in both relative and absolute terms. Our results have global implications given the prevalence of dairy as a source of income and nutrition in high- and low-income contexts.

Therefore, an effective and low-cost strategy is urgently required to improve the dietary diversity of rural households. Short-form video platforms (SVPs) are emerging media that can deliver diet-related information, and their potential impact on the dietary diversity of rural households cannot be neglected. Based on primary data collected from rural households in China, this study employs the IV-Poisson model to explore whether SVPs improve the dietary diversity of rural households, uses the IV-Probit model to examine whether SVPs encourage rural residents to consume food groups that are not self-produced, and applies the endogenous-treatment Poisson regression (ETPR) model to identify the heterogeneous effects of SVP participation on the dietary diversity of rural households with different distances from the county center. The results reveal that household cooks’ participation in SVPs significantly increases the dietary diversity of rural households. Specifically, households in which cooks participate in SVPs have 29.5% higher household dietary diversity scores than those in which cooks do not. The results indicate that household cooks’ participation in SVPs encourages rural residents to consume food groups that are not self-produced, thus improving their dietary diversity. In addition, the results indicate that household cooks’ participation in SVPs has a greater positive effect on the dietary diversity of rural households closer to the county center compared to those farther from the center.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102797"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143138885","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}

Policy measures are one potential lever for shifting consumption towards more sustainability. Public acceptance can be a major barrier for the implementation of such measures.

In the present study, we therefore invited 453 participants from German-speaking parts of Switzerland to participate in an online survey in which we tested 15 policy measures for their consumer acceptance. Furthermore, we explored individual predictors that contribute to policy support. Our results show that there is a difference in the support of policy measures depending on the level of intrusiveness, making less intrusive measures more accepted than more intrusive measures. Support also varied depending on the targeted product category. Measures targeting dairy and meat products tended to be less accepted than measures targeting vegetables. Using a regression analysis, we identified behaviour (i.e. meat and dairy consumption) and food sustainability knowledge as an important predictor of policy support. The findings have important implications for policymakers, as they illustrate that personal involvement is a crucial factor in policy support. Taken together, our findings can help inform future food policies to increase consumer support and thereby facilitate sustainable behaviour change.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102822"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143138888","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}

Using a dataset with monthly bilateral dairy trade flows at the 6-digit level from January 2014 to October 2023, we empirically assess the economic outcomes associated with this dispute from the perspective of the U.S. dairy industry. We find that — even under Canada’s original quota administration procedures — Canadian dairy TRQ concessions represented meaningful trade liberalization relative to the pre-USMCA status quo. However, in light of Canada’s revised procedures following the panel ruling, U.S. exports to Canada experienced a substantial increase for affected dairy products.

A total of 542 provisions concerning AOW were identified, while 234 and 181 provisions also addressed LSW and LCW, respectively. As regards LCW, specific regulations included the prohibition of the claws banding (85.1%), slaughter prior to sale (59.1%), and boiling of live crustaceans (33.1%). Conversely, the obligation to slaughter before sale (12.1%), after stunning (10.5%) and out of sight of the consumer (5%) were reported. The divergent and generally not scientifically-based nature of the regulations suggests limitations of the Italian approach in AOW, LSW and LCW management.

We conceptualise global agricultural R&I cooperation (ARIC) to examine how the changing nature of the cooperation between major players from the North and the South influences ARIS transformation in the South.

We explore LGN’s feasibility through a case study of UK-China cooperation to illustrate the necessity and key factors influencing the participation of non-academic actors including smallholder farmers in ARIC. Evidence for this paper comes from a combination of primary data collected from 52 British scientists, representatives of funding agencies and entrepreneurs regarding their experiences, opinions and perceptions of ARIC through bilateral cooperation, and second sources. This paper contributes to ARIS transformation debates from three perspectives. First, it sheds new light on transformative innovation debates by adding an ARIC element for ARIS transformation in the South. Second, it enriches a “pathways approach” by delineating four pathways of ARIC, as well as top-down and bottom-up processes across various scales.

Food price shocks, indeed, generate both winners and losers and their overall impact on income distribution cannot be predicted a priori but depends on the relative magnitude of different effects. From the empirical perspective, however, the link between international food prices and income distribution is largely understudied. The present paper tries to fill the gap by analyzing a large sample of 126 developing and developed countries observed in the period 1990–2020 and studying how food price shocks are associated with changes in income distribution. The heterogeneity of the effect is investigated by means of interaction terms accounting for the food trade balance of countries and the structure of the agricultural sector, coming to three main conclusions. First, upsurging food prices increase inequality by affecting the relative income of the poorest 50 percent of the population to the advantage of richer people, especially of the richest among the rich. Second, this effect is relevant for developing countries while no clear findings emerge for high-income countries. Third, the disequalizing effect of soaring international food prices is not uniform in developing countries but largely depends on their food trade balance and some structural attributes of their agricultural sector. In this regard, food policy must reduce the domestic transmission of price shocks to poor consumers while strengthening farmers’ productive capacity and ability to cope with the shocks through better access to land, capital and productive resources.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102830"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510806","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}
