However, conventional, sector-specific implementation undermines these aims, restricting multifunctionality, increasing maladaptation risks and limiting long-term effectiveness. We contrast such trajectories with systemic NbS pathways that embed adaptive co-management, integrated indicators, and aligned governance and finance. We propose an NbS services approach that operationalizes established standards and criteria by linking ecological performance to continual learning and results-based mechanisms. This approach integrates robust biodiversity, ecosystem function and equity indicators into composite performance metrics and applies participatory adaptive co-management to evaluate trade-offs, manage uncertainty and improve outcomes over time, including the support of simulation-based tools. Governance–finance alignment through transparent, pay-for-results mechanisms further supports transformative implementation. Framing NbS implementation as the delivery of continuous, auditable services strengthens ecological integrity, inclusiveness and comparability, enabling a shift from fragmented projects to cross-sectoral adaptation that addresses intertwined climate, water and biodiversity challenges. This Perspective examines how a systemic, service-oriented framing of nature-based solutions can enhance multifunctionality and long-term resilience within complex social–ecological systems. Aligning adaptive co-management, integrated indicators and governance–finance structures enables nature-based solutions interventions to address interconnected climate, biodiversity and water challenges.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"699-710"},"PeriodicalIF":30.7,"publicationDate":"2026-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292567","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}

Sorption-based atmospheric water harvesting (SAWH) offers promising routes to address global water scarcity without spatial or temporal limitations. Unfortunately, low water sorption–desorption kinetics are long-standing challenges when sorbent powders are densely packed at the device scale for practical utilization. Here we report a scalable and flexible mixed-matrix membrane (MMM) by confining zeolite-like EMM-8 nanosheets into macroporous thermoplastic polyurethane (TPU) networks via three-dimensional printing and in situ solvent exchange. This sorbent membrane (EMM-8@TPU) features multiscale hierarchically porous structures for ordered mass transport, achieving ultrafast water sorption–desorption. We further engineer scalable multiscenario SAWH prototypes for ultrafast water harvesting: roll-to-roll rotational MMMs achieve sunlight-driven SAWH, and layer-by-layer-assembled MMMs realize electric-driven SAWH, reaching impressive water productivity up to 13.79 gwater gsorbent−1 d−1. Our work represents promising routes for designing next-generation water sorbents via assembling sorbent powders into hierarchically ordered membranes. This work presents a scalable and flexible mixed-matrix membrane to overcome mass-transport limitations in sorption-based atmospheric water harvesting, enabling ultrafast sorption–desorption kinetics and high-productivity water harvesting prototypes driven by sunlight or electricity.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"823-834"},"PeriodicalIF":30.7,"publicationDate":"2026-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292557","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 extensive research on their transformation by animals and bacteria, the interactions between phytoplankton and progestogens remain poorly understood. Here we show the efficient biotransformation of a representative progestogen norethindrone acetate (NEA) across 18 phylogenetically diverse freshwater and marine phytoplankton species, primarily through enzymatic conversion into the more potent neurosteroid norethindrone. Using click chemistry-based chemoproteomics combined with protein functional validation, we found that an adenylosuccinate lyase induced an unexpected deacetylation of NEA into norethindrone. Using metagenome and metatranscriptome databases, we uncovered the global distribution and transcription of genes encoding this lyase across various eukaryotic phyla. Our study demonstrates an overlooked reconversion of NEA by diverse phytoplankton species, which may exacerbate the risks of progestogens such as NEA to ecosystem health and human safety. Endocrine-disrupting progestogens pose risks to ecosystems through their biological activity. A chemoproteomics study shows that many phytoplankton species can transform these chemicals into forms that may be even more biologically active, potentially increasing ecological risk.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"776-787"},"PeriodicalIF":30.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292562","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}

The complex water cycle facilitates the transmission of antibiotics, resistant bacteria and resistance genes that have been released through anthropogenic activities, thereby reshaping AMR dynamics across different environmental compartments. Among these resistance determinants, inactivating antibiotic resistance genes (inactivating ARGs) encode enzymes that degrade or modify antibiotics to reduce their bioactivity. They play a complex and dual role bridging environmental reservoirs and clinical risk. While they can threaten the therapeutic effectiveness of antibiotics when transferred horizontally to pathogens, they also act as cooperative traits that lower local concentrations of bioactive antibiotics and relax selection for resistance. In turn, reduced antibiotic exposure can enhance ecosystem functions and stability in both host-associated and environmental microbiomes through ecosystem resilience and community protection. Inactivating ARGs represent a crucial intersection between AMR challenges and microbial community stability. Here we discuss the risks and ecological benefits of inactivating ARGs, and present intervention strategies aiming to both protect ecological resilience and limit resistance development in pathogens. Water environments are pivotal in the spread of antimicrobial resistance, acting as conduits for antibiotics and resistance genes. Here, the authors explore the dual role of inactivating antibiotic resistance genes, highlighting their ecological benefits and risks, and propose strategies to enhance ecosystem resilience while curbing resistance in pathogens.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 5","pages":"550-558"},"PeriodicalIF":24.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148003754","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}

However, current knowledge of the impacts of urbanization on microbial communities in WWTPs remains ambiguous. Here we show that urbanization and operational conditions jointly shape microbial diversity and homogeneity in WWTPs. By analysing 934 samples from 217 WWTPs across the globe, we found that urbanization factors such as city population size and economic development are strongly associated with changes in community similarity. Population size is likely associated with increased similarity among communities, while socio-economic development shows the opposite association. In contrast, operational conditions, including sludge retention time and substrate concentration, present a relatively high explanation degree for microbial community richness. In particular, we observed that homogenized communities and a loss of diversity correlate closely with performance and stability. This study provides a global-scale assessment of how urbanization and operational factors interact to shape microbial communities in WWTPs. Urbanization is reshaping microbial ecology within wastewater treatment systems. This study reveals that urbanization drives microbial homogenization and that reduced diversity is linked to poorer wastewater treatment performance and stability.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 6","pages":"802-813"},"PeriodicalIF":30.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292563","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}
