The depletion of numerous global aquifers, however, raises concerns regarding the sustainability of groundwater withdrawals and environmental flows. Despite efforts to mitigate this decline, there remains a striking gap in proving the effectiveness of these measures. Our research focuses on the karstic Edwards Aquifer system in Texas to assess how effectively current mitigation strategies are protecting groundwater levels and spring flows, which are essential for biodiversity and water security. Using counterfactual artificial intelligence, we address the critical question: ‘What would have happened and may happen in the absence of the mitigation measures?’. This approach offers deep insights into both historical impacts and future projections under intermediate- and high-emission climate scenarios. By simulating what might have happened and could happen in the future without these mitigation measures, our approach provides a robust analysis of the real-world benefits of groundwater management strategies, highlighting their role in enhancing climate resilience and ensuring the sustainability of aquifers. Mitigation policy is critical for counteracting aquifer depletion, but measuring its success can be difficult. A counterfactual approach employing artificial intelligence can provide novel insights into the efficacy of mitigation policies.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 1","pages":"44-53"},"PeriodicalIF":25.7,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01477-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121574","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}

Science-based target setting has emerged as a powerful tool to help achieve the potential, but its uptake has been limited. Moreover, cities and companies usually develop their targets separately, even though many are co-located. Focusing on the top 200 cities and 500 companies by greenhouse gas emissions, we analyse the current state and potential of adopting science-based targets for climate. Of these key actors, 110 cities with existing net-zero targets and 22 companies with existing science-based targets could together eliminate up to 3.41 GtCO2e of annual emissions. We argue that this reduction potential could increase by as much as 67% (to 5.70 GtCO2e) if the cities and companies that already have targets bring their co-located counterparts on board to keep abreast of their ambitions. Using freshwater as another example, we discuss entry points for addressing interrelated Earth system boundaries through city–company collaborations. Our findings elucidate previously untapped potentials that could accelerate transformations for operating within Earth system boundaries. Many of the world’s largest cities and leading companies have separately adopted targets for emissions and water-use reductions. This study examines how co-location and collaboration could enhance efforts to stay within Earth system boundaries.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 1","pages":"54-65"},"PeriodicalIF":25.7,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01473-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121633","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}

Scientists’ limited experience in reflecting on their guiding assumptions, combined with a tendency to inflate their own research findings, hinders interdisciplinary dialogue and limits the usefulness of science. Through bibliometrics and discourse analysis, we analysed highly cited articles on agroecology and sustainable intensification. In broad terms, agroecology prioritizes diversity while sidelining productivity and adheres to relational epistemology, while sustainable intensification emphasizes boosting crop production while reducing environmental impact within a reductionist epistemology. Both discourses claim to have the solution to agricultural sustainability but are largely inexplicit about their guiding assumptions and their own limitations, and rarely engage with research in the other discourse. Interdisciplinary dialogue based on transparent and self-critical reflection on the assumptions and limitations of research could increase the relevance of science in societal dialogues about alternative pathways towards sustainable agriculture. Two major discourses for agricultural sustainability, agroecology and sustainable intensification, have produced extensive research bases, but do not engage or overlap with each other. This analysis examines how these ‘silos’ may hamper further research.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 1","pages":"66-74"},"PeriodicalIF":25.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01474-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121568","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}

NCS can generate win–win co-benefits for biodiversity and human well-being, but they can also involve trade-offs (co-impacts). However, the massive evidence base on NCS co-benefits and possible trade-offs is poorly understood. We employ large language models to assess over 2 million published journal articles, primarily written in English, finding 257,266 relevant studies on NCS co-impacts. Using machine learning methods to extract data (for example, study location, species and other key variables), we create a global evidence map on NCS co-impacts. We find that global evidence on NCS co-impacts has grown approximately tenfold in three decades, and some of the most abundant evidence relates to NCS that have lower mitigation potential. Studies often examine multiple NCS, indicating some natural complementarities. Finally, we identify countries with high carbon mitigation potential but a relatively weak body of evidence on NCS co-impacts. Through effective methods and systematic and representative data on NCS co-impacts, we provide timely insights to inform NCS-related research and action globally. Rich evidence of the potential co-benefits and trade-offs of natural climate solutions is available but remains poorly understood. Assessing the literature with machine learning methods, this study maps and analyses the growing evidence of trade-offs in natural climate solutions globally.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 1","pages":"75-85"},"PeriodicalIF":25.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121541","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}
