Here we use an integrated model to quantify how carbon neutrality policies pledged by 153 countries affect yields of maize, rice, soybean and wheat and the associated economic outcomes. We show that excluding ozone change may understate the benefits of existing carbon neutrality policies for the four main crops, by up to 38.7%. By including the combined effect of ozone and climate, carbon neutrality policies can prevent 0.5–41.5% in losses, and more than 70% of the crop area would experience crop gains compared with the no policy scenario. For countries that still experience agricultural losses, we discuss options to reduce food security risks in terms of mitigation policies, adaptation measures and agricultural trade agreements. The spread of carbon neutrality pledges calls for robust estimates of their agricultural and economic impacts. Using an integrated assessment framework that links climate, atmospheric chemistry, agriculture and economic modules, this study shows that accounting for ozone increases the estimated crop and economic benefits of these pledges.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"441-451"},"PeriodicalIF":21.9,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147984893","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}

To address this, countries around the world implement a range of public policies. We used global satellite remote sensing data (~83 million measurements of cropland condition from 2001 to 2019) and 2 complementary quasi-experimental impact evaluation methods (difference in discontinuities and difference in differences) to assess the impact of these policies on the state of the world’s cropland. We found that, on average, these policies have improved cropland globally by at least 2% and possibly up to 5%. Country-level heterogeneities reveal effects ranging from 0 to over 20%. This heterogeneity is explained by differences in countries’ institutional and governance characteristics and policy budgets. Moreover, by estimating variation in policy intensity across policy types, we found that agri-environmental payments and soil and land-use regulations were most effective, yielding estimated improvements of 0.8% and 0.9% per additional policy. Evidence on the effectiveness of national policies against cropland degradation is limited. Using global satellite data from 2001 to 2019, this study addresses this gap and reveals which country characteristics are associated with distinct policy success levels.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 6","pages":"527-538"},"PeriodicalIF":24.7,"publicationDate":"2026-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s43016-026-01359-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147978257","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 test this by combining a continental-scale warming microcosm experiment across 100 paired agricultural–natural sites with a global meta-analysis and three microbiome manipulation experiments (microbial suspensions, cross-inoculation and synthetic communities). Agricultural soils showed a higher resistance of soil multifunctionality to warming than natural soils, consistent across the meta-analysis. Resistance of microbial community composition was the strongest predictor of functional resistance and was confirmed in artificial soils inoculated with agricultural versus natural microbial suspensions. Introducing soil microbiomes from agricultural ecosystems into previously undisturbed natural soils enhanced functional resistance to warming. Metagenomic analysis revealed that microbial life-history strategies play a crucial role in regulating the resistance of soil microbial community to warming, with communities dominated by stress-tolerant strategies conferring significantly stronger resistance. Our work highlights the potential of microbiome engineering to strengthen ecosystem functioning under climate change. Using warming microcosms across 100 paired sites, a global meta-analysis and microbiome manipulation experiments, this study shows that agricultural microbiomes confer higher compositional and multifunctionality resistance to warming and can transfer this resistance to natural soils.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"428-440"},"PeriodicalIF":21.9,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147950496","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 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}
