Here we used modern portfolio theory to explore Pareto-optimal spatial arrangements of global rainfed cropping that explicitly account for trade-offs between total crop production and its interannual variability (risk). We analysed production/risk trade-offs under recent historical climate and yields for 2010, as well as under business-as-usual (RCP 6.0) and ambitious mitigation (RCP 2.6) climate futures for 2050. We found that optimizing the spatial distribution of rainfed crops could increase global production by 10.1% while maintaining the same level of risk as in 2010 or, alternatively, reduce production variability by 33.1% while maintaining the same level of production level as in 2010, all without additional land or water. Optimal global rainfed cropping patterns could meet future food demand with enhanced resilience under increased climate variability but only with yield-gap closure and more open and globalized trade, highlighting the need for coordinated production strategies, strengthened trade cooperation and sustainable intensification within climate adaptation policy. Spatial optimization can reduce production risk and improve output without expanding land or irrigation, but meeting future demand will require a combined strategy of global crop redistribution, yield-gap closure and stronger trade cooperation.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 6","pages":"577-588"},"PeriodicalIF":24.7,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261141","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, using a machine learning approach, we analyse 848 global manure, food waste and sewage sludge composting experiments, identifying 19 key management parameters that drive ammonia (NH3), nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) emissions. We estimate annual global losses during the composting process at 747 kt NH3-N, 81 kt N2O-N and 592 kt CH4-C, equivalent to ~61 MtCO2e yr−1. By optimizing organic waste processing strategies, such as adjusting aeration, additives and C/N ratios, the composting chain could transition from a net emitter (40.1 MtCO2e) to a C sink (−15.1 MtCO2e), while conserving nutrients for crops. Under an optimal reduction scenario, China, Brazil and the United States emerge as the top three C sinks for composting, collectively accounting for 65% of total emission reductions. Organic waste mismanagement can degrade soils and increase pollution.

Here we examined how lacking food and food safety covaried with lacking clean drinking water, using World Risk Poll data from 121 countries across country-income levels (N = 124,003). Lacking food for more than a day in the past year was associated with lacking clean drinking water for more than a day in the past year. Participants who lacked both food and clean water, or either alone (versus neither) were more likely to experience food safety threats and be concerned about food safety. Relationships held across country-income levels. Low-income countries (especially in Eastern Africa) and high-income countries (especially in Northern America) showed compounded effects of lacking food and clean drinking water on food safety. Worldwide, food insecurity, food safety and water insecurity should be addressed jointly. Food preparation typically requires access to clean drinking water. This Analysis of data from the World Risk Poll explores the links between food sufficiency, clean drinking water availability and their impact on food safety threats across low-, middle- and high-income regions.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 6","pages":"613-620"},"PeriodicalIF":24.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148145985","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}

Based on concrete examples, we propose five guiding principles that, in various combinations, can help address lock-ins and guide effective changes towards more healthy and sustainable food systems. Their successful implementation requires strong, experience-inspired, science-based political and business leadership supported by a revised research and innovation agenda.

Here, using three independent approaches—a data-driven model, a process-based ecosystem model and a meta-analysis of over 1,255 field experiment sites—we estimate that net GHG emissions from global rice paddies approximately doubled from 1961–1980 to 2001–2020, driven primarily by a 52% increase in soil CO2 emissions and a 44% rise in soil CH4 emissions. For the most recent decade (2010s), global rice paddies emitted 1,090 ± 350 Tg of CO2-equivalent emissions (CO2e) per year, with an emission intensity of 0.33 ± 0.08 MgCO2e per million kilocalories. Rice area expansion was the largest contributor to net GHG increases, with secondary drivers being the widespread adoption of intensified residue incorporation. East Asia experienced renewed CH4 increases linked to excessive straw incorporation, while Africa emerged as an important CH4 hotspot because of rapid paddy expansion. Mitigation strategies such as reducing excessive residue and nitrogen inputs alongside the adoption of optimal tillage and irrigation could reduce future total net GHG emissions by ~10% without yield loss. However, achieving further reductions will require stronger climate-smart policy frameworks. Rice paddies are crucial for food security but are also a major source of greenhouse gas (GHG) emissions. This study found that net soil GHG emissions nearly doubled from 1961–1980 to 2001–2020, mainly due to soil carbon stock change-derived CO2-equivalent emissions and soil methane emissions, underscoring the need for climate-smart management.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"7 5","pages":"474-487"},"PeriodicalIF":21.9,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148007711","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}
