Degrowth posits a radical pathway of transformation to reduce ecological impacts while increasing well-being and reducing inequality. Here we highlight that degrowth and food systems—albeit both linked to transformation—are not well integrated. We conduct a conceptual exploration of the potential alignment between key food systems and degrowth transformation measures, arguing for complementary and reciprocal perspectives to theorize and enact transformation. Finally, we offer concrete practical actions to integrate degrowth and food systems, thereby widening the narrative and analytical lens of social–ecological transformation. To address the view that degrowth and the food system are not well aligned, this Perspective offers concrete practical actions to integrate the two, thereby widening the narrative and analytical lens of social–ecological transformation.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 1","pages":"19-24"},"PeriodicalIF":23.6,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917024","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}

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}

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}
