Here we evaluate the growth trajectories and ecological footprints of different aquaculture systems in China, considering both business as usual and ecological transformation scenarios, and anticipate the evolution of sustainable aquaculture in the post-carbon neutrality era. We explore a two-step approach involving ecological transformation and green aquaculture. By adjusting the annual growth rates of six out of nine aquaculture systems, energy use, nitrogen discharge, land use and freshwater usage per unit of mass gain could be reduced by 1.70%, 6.89%, 7.12% and 8.86%, respectively, by 2050 compared with the business as usual levels. Owing to changes in the energy supply mix in China, by 2050, the total CO2 emissions from aquaculture will only increase by 5.7% compared with the level in 2021. Once carbon neutrality is attained, the focus should shift to mitigating nutrient discharges. Our findings underscore the necessity for substantial improvement in the Chinese aquaculture development plan and offer a blueprint for sustainable aquaculture advancement for guiding policy and practice.","PeriodicalId":19090,"journal":{"name":"Nature Food","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143385269","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}

Subsoils, below 20 cm, underpin fundamental agroecosystem sustainability traits including soil carbon storage, climate regulation and water provision. However, little is known about the ecological stability of subsoils in response to global change. Here we conducted a microcosm experiment to determine whether subsoils were more sensitive to global changes across 40 agricultural ecosystems in China, in combination with a multiple global change factor experiment and an in situ field study. We found that subsoils exhibited greater fluctuation in species diversity, community composition, and complexity of microbial networks and ecosystem functions than topsoils, indicating lower resistance to global changes. Soil biodiversity was a major driver of ecosystem resistance, surpassing climate and soil parameters. A reciprocal microorganism transplant experiment showed that microorganisms isolated from the topsoil are more resistant to global changes than those from subsoil. Our study emphasizes that subsoil ecosystems are sensitive to global changes, underscoring the importance of including subsoils in predictions of agricultural sustainability and crop productivity under changing environmental conditions.","PeriodicalId":19090,"journal":{"name":"Nature Food","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916872","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}
