Understanding their relative importance can optimize intervention design and impact. Here we used panel data on 2,612 women from a 1:1 cluster-randomized trial of 96 settlements in rural Bangladesh and conducted multiple mediation analysis to investigate the impact pathways of a 3-year HFP intervention on women’s dietary diversity. The pathways analysed fully explained the intervention’s total effect on dietary diversity score, amounting to an increase of 0.4 (95% confidence interval (CI) 0.3–0.5) food groups on a 10-point scale. Garden production accounted for 78% of the increase (β = 0.33 (95% CI 0.25–0.42)), emerging as the key component to improving dietary diversity. Nutrition knowledge accounted for 18% of the increase, while poultry production and market activity made smaller contributions. These findings can guide the design of future HFP interventions, but similar analyses are needed across a range of interventions, outcomes and settings to build a robust evidence base for improving nutrition. The contribution of homestead food production (HFP) to nutrition and dietary diversity is context-specific and involves multiple pathways. Using panel data on 2,612 women in 96 settlements in rural Bangladesh, this study identifies and measures the impact pathways of a 3-year HFP intervention.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"464-473"},"PeriodicalIF":21.9,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s43016-026-01354-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147936500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we conduct a meta-analysis of over 3,000 empirical observations to assess the mitigation performance of integrated technologies within livestock farms. Mitigation options are categorized into low-cost and easily scalable technologies and precision-integrated technologies, with the latter performing better by reducing reactive nitrogen and non-CO2 greenhouse gas emissions by two-fifths and one-third, respectively. High-efficacy hotspots emerged in North America, Europe and East and Southeast Asia. Beyond current practices, a transition towards an integrated management framework centred on enclosed manure-treatment systems offers further reductions of over half for reactive nitrogen and two-thirds for non-CO2 greenhouse gas by 2050. Meeting net-zero targets will require sustained capture of almost three-quarters of CO2 from these systems. These findings highlight the critical role of integrated approaches for advancing sustainable and climate-resilient livestock production systems. A meta-analysis of ~3,000 empirical observations shows that systemic shifts in manure management and technology integration can reduce reactive nitrogen and carbon dioxide emissions from global livestock systems under various mitigation scenarios.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"416-427"},"PeriodicalIF":21.9,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147877094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we assessed China’s plant-based food supply during 1997–2018 to determine its ability to meet population-level requirements for dietary energy and 17 nutrients and evaluated food system scenarios for improving nutrient coverage and source diversity. In the baseline scenario including animal-based foods, coverage was high for energy, protein, carbohydrates, dietary fibre and ten micronutrients; medium for riboflavin and vitamin A; and low for calcium and selenium. Halving food loss and waste, increasing whole-grain use and moderating red meat intake improved coverage for all nutrients by 8–44% above baseline. Redirecting crops from feed and non-food uses to human consumption enabled self-sufficiency for energy and 14 nutrients. While food system improvements in China can strengthen nutrient availability, complementary strategies, such as crop diversification, fortification and biofortification are needed to close the remaining gaps. China’s plant-based food supply provides much of the population’s energy and nutrient needs, but key micronutrient gaps persist. Nutrient coverage can be strengthened by reducing food loss and waste, increasing whole-grain use, moderating red meat intake and repurposing crops from feed and non-food uses to direct human consumption.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"452-463"},"PeriodicalIF":21.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s43016-026-01349-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147825128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
