Despite regulatory efforts, such as the European Union’s Nitrogen Directive, high concentrations of N persist in freshwaters. Excessive N leaching and accumulation in groundwater has created a substantial N reservoir as groundwater travel times are orders-of-magnitude slower than those of surface waters. In this study we reconstructed past and projected future N dynamics in groundwater for four major river basins, the Rhine, Mississippi, Yangtze and Pearl, showcasing different N trajectories. The Rhine and Mississippi river basins have accumulated N since the 1950s and although strategies to reduce excess agricultural N have worked well in the Rhine, groundwater legacy N persists in the Mississippi. The Yangtze and Pearl river basins entered the N accumulation phase in the 1970s and the accumulation is expected to continue until 2050. Policies to reduce N pollution from fertilizers have not halted N accumulation, highlighting the importance of accounting for the N legacy in groundwater. Restoring groundwater N storage to 1970 levels by diminishing N leaching will therefore take longer in the Yangtze and Pearl (>35 years) than in the Rhine (9 years) and Mississippi (15 years). Sustainable watershed management requires long-term strategies that address the impacts of legacy N and promote sustainable agricultural practices aligned with the Sustainable Development Goals to balance agricultural productivity with water conservation. National and international policies have aimed to protect the quality of freshwater by mitigating agricultural nitrogen emissions. However, the nitrogen legacy in groundwater must be accounted for when mitigating the impacts of nitrogen in watersheds.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 7","pages":"891-900"},"PeriodicalIF":25.7,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01369-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141351290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A review of existing work shows that there are interesting parallels between these fields. By carefully defining key concepts, such as regenerative dynamics, regenerative practices and regenerative momentum, this Review Article offers a generalized framework for understanding regenerative systems. This framework, in turn, promises to spark new insights for sustainability science and practice because it can link hitherto disconnected academic fields and foster new, integrative developments across multiple areas of sustainability practice. Contemporary discussions about sustainability and adaptation rely on concepts of regeneration. Linking regenerative dynamics and practices from disparate disciplines provides a framework for employing regenerative systems to advance cross-domain sustainability science.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 8","pages":"964-972"},"PeriodicalIF":25.7,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141352294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital technology, such as edge artificial intelligence (AI), has the potential to introduce substantial benefits to agriculture by enhancing farming practices that can improve agricultural production efficiency, yield, quality and safety. However, the adoption of edge AI faces several challenges, including the need for innovative and efficient edge AI solutions and greater investment in infrastructure and training, all compounded by various environmental, social and economic constraints. Here we provide a roadmap for leveraging edge AI at the intersection of food production and sustainability. Digital technology is increasingly being used to address food security issues against the backdrop of anthropogenic stressors such as climate change and resource scarcity. This Perspective discusses ways to effectively deploy edge AI in food production systems to improve agricultural sustainability.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 7","pages":"846-854"},"PeriodicalIF":25.7,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141360540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the future expansion of hydropower on the continent faces obstacles due to the impacts of dams on rivers, greenhouse gas emissions from reservoirs and increasingly competitive alternative renewable electricity technologies. Here we propose an integrated approach to include these considerations in energy planning. Compared with planning for least-cost energy systems, capacity expansion strategies balancing environmental and techno-economic objectives increase electricity prices and total discounted costs by at most 1.4% and 0.2%, respectively, while reducing impacts on annual hydropower emissions and river fragmentation by at least 50%. Our results demonstrate that refining techno-economic analysis in light of global and local environmental objectives can help policymakers reduce the river fragmentation and greenhouse gas emissions associated with hydropower development at marginal increases in energy costs. Meeting future energy demands in Africa will require expanded hydropower capacity, but the dams’ impacts on rivers, their emissions and alternative energy options call for careful planning. This study performs multi-objective energy system modelling for more sustainable dam expansion from the present to 2050.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 7","pages":"879-890"},"PeriodicalIF":25.7,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141267914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we introduce an approach for identifying gauging sites to efficiently fill gaps in monitoring coverage within river networks while also addressing water management priorities, including reservoir operations, biodiversity conservation and hydroclimatic monitoring. Applying this approach to gauges in California, United States, we found substantial gaps in the stream monitoring network. Hypothetically reconfiguring gauges to locations that maximize coverage and representation of management objectives highlights the current network’s biases. Through the strategic reactivation and placement of additional gauges, we demonstrate how stream gauging networks can be designed to support sustainable water management. Effective water management requires reliable data on streamflow, but that hinges on the coverage provided by stream gauges. This study shows how current gauge networks fail to provide adequate coverage and explores how modified networks could support dam operation, biodiversity conservation and climate monitoring.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 6","pages":"714-723"},"PeriodicalIF":25.7,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate their environmental footprints, there is an urgent need to develop an efficient recycling method to handle end-of-life Si solar panels. Here we report a simple salt-etching approach to recycle Ag and Si from end-of-life Si solar panels without using toxic mineral acids and generating secondary pollution. The etching process is enabled by the high corrosivity of molten hydroxide that spontaneously reacts with SiNx, SiO2, Al2O3 and Al at the surface of Si wafers through the top-down direction, thereby directly separating Ag from Si wafers. The etching process takes only 180 s to recover >99.0% of Ag and >98.0% of Si from end-of-life Si solar panels. In addition, Cu, Pb, Sn and Al in Si solar panels are also recovered through a combined oxidation, alkaline leaching and electrodeposition approach. Overall, this study presents a viable approach for sustainable management of end-of-life Si solar panels, paving the way to a circular economy. The booming production of silicon solar panels, a core technology in the energy transition, calls for proper end-of-life management. Here the authors propose a salt-etching approach that enables efficient recycling of critical materials from end-of-life silicon solar panels, without the use of toxic reagents.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 7","pages":"920-930"},"PeriodicalIF":25.7,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
