Post-harvest, retail and consumer losses and waste could be reduced with better ripeness assessment methods. Here we develop a sub-terahertz metamaterial sticker (called Meta-Sticker) that can be attached to a fruit to provide insights into the edible mesocarp’s ripeness without cutting into the produce. The fruit acts as a complex multilayer substrate to Meta-Sticker and, when excited by sub-terahertz signals, generates two distinct resonances: localized dipole resonance that correlates with the exocarp’s refractive index; and propagating plasmon resonance that penetrates into the mesocarp and resembles the rare phenomenon of ‘extraordinary transmission’. The Meta-Sticker accurately predicted the ripeness of different fruits with a cumulative normalized root mean square error of 0.54% of the produce tested. This study offers a non-invasive, low-cost and biodegradable solution for accurate ripeness assessment with applications in distribution optimization and food waste reduction. Fresh produce can be wasted at many stages of the food supply chain. A metamaterial sticker is developed based on sub-terahertz signals to detect fruit ripeness, which can be used to optimize distribution and for waste prevention.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 1","pages":"97-104"},"PeriodicalIF":23.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43016-024-01083-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911927","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 present a digital DNA-amplification-free nucleic acid detection assay to achieve multiplexed and ultrasensitive detection of three food-borne pathogens. We used mesophilic Clostridium butyricum argonaute and magnetic beads in a digital carrier system (d-MAGIC). Clostridium butyricum argonaute, with its two-guide accurate cleavage activity, precisely targets and cleaves fluorescence-quencher reporters corresponding to different bacteria through a two-step process. The system uses fluorescence-encoded magnetic beads as programmable multi-probes, allowing the simultaneous detection of multiple pathogens and easy data interpretation via artificial intelligence. The method showed a wide detection range (101 to 107 CFU ml−1) and a low limit of detection of 6 CFU ml−1 for food-borne pathogens without DNA amplification. Digital nucleic acid testing using d-MAGIC can become a next-generation strategy for accurate and convenient pathogen detection. A method for detecting Salmonella enterica subsp. enterica serovar Typhimurium, Staphylococcus aureus and Listeria monocytogenes is developed, enabling simultaneous and rapid artificial-intelligence-assisted food-borne pathogen detection.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 2","pages":"170-181"},"PeriodicalIF":23.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911928","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}

Despite its importance in agricultural production, labour has been overlooked when exploring the agrifood–water–environment–climate nexus. Here we incorporate evolving labour markets into multisector dynamic modelling to examine their agroeconomic and environmental implications. Our projections show that the recent decline of global agricultural employment persists, with an estimated decadal decrease of 43 million people by 2100, strengthening the decoupling of labour from production. Exploring scenarios with varying labour productivity and supply factors, we also show a positive relationship between productivity-adjusted labour supply and agricultural emissions, with more pronounced and heterogeneous regional and sectoral responses. While highlighting the pressing need to capture labour dynamics in integrated human–Earth systems, our study lays the foundation for further investigation into labour market responses and feedback in broader scenarios. Labour productivity and labour market transitions are key to the future of agriculture. By simulating agricultural labour input demand in production technologies and incorporating a wage-responsive labour supply, this study sheds light on the dynamics of future agricultural labour market evolution.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 2","pages":"139-150"},"PeriodicalIF":23.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911929","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}

China has implemented stringent wastewater policies, established numerous treatment facilities and enforced rigorous water quality standards to address pollution in its waterways. However, the impact of these policies on seafood safety and methylmercury exposure remains unknown.

Furthermore, these policies ensured that $${146}_{-9}^{+8}$$ megatonnes of freshwater seafood met the World Health Organization and China’s mercury-safety standards, preventing $${mathrm{US}}${498}_{-29}^{+32}$$ billion in economic losses. Finally, we explore how China, as the primary global seafood producer and exporter, could develop municipal wastewater policies at the regional level to reduce aquatic pollutants and unlock the health benefits of seafood consumption. Seafood methylmercury contamination is a global food safety issue.

As most rural households in the region are involved in farming, the diversification of own farm production could improve their access to nutritious foods. Here we use representative panel data from six African countries to estimate this effect across different scales. We show that farm production diversity is positively associated with household dietary diversity—yet the average magnitude of the association is small, depends on the specific measure of production diversity and increases with distance from urban centres. In all countries, markets and market access are more important for dietary diversity than own production. Because village-, town- and district-level production diversity are often positively associated with dietary diversity, higher diversity on each individual farm may not be required. The appropriate spatial scale should be considered when designing diversification strategies. Evidence on the effect of own farm diversification on access to nutritious foods and dietary diversity is mixed, with most studies using cross-sectional data from specific settings. An analysis of panel data from six African countries helps map and estimate this association across different scales.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 2","pages":"205-212"},"PeriodicalIF":23.6,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43016-024-01096-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911926","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}

Alternate wetting and drying (AWD) is a promising irrigation strategy to improve paddy rice’s water productivity—defined as the ratio of rice yield to irrigation water use. However, its global adoption has been limited due to concerns about potential yield losses and uncertainties regarding water productivity improvements. Here, using 1,187 paired field observations of rice yield under AWD and continuous flooding to quantify AWD effects (ΔY), we found that variation in ΔY is predominantly explained by the lowest soil water potential during the drying period. We estimate that implementing a soil water potential-based AWD scheme could increase water productivity across 37% of the global irrigated rice area, particularly in India, Bangladesh and central China. These findings highlight the potential of AWD to promote more sustainable rice production systems and provide a pathway toward the sustainable intensification of rice cultivation worldwide. Alternate wetting and drying (AWD) optimizes water use in rice cultivation. This study shows that a soil water potential-based AWD scheme could minimize yield loss while increasing water productivity in 37% of global irrigated rice areas.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"5 12","pages":"1005-1013"},"PeriodicalIF":23.6,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678665","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}
