So far, studies addressing spatiotemporal variability in and drivers of salt marsh biogeochemical function, carbon storage and resilience have focused on ocean-driven surface hydrologic influences, neglecting effects of terrestrial hydrology through subsurface connections. Here we evaluate drivers of salt marsh redox potential, a proxy for biogeochemical state, through wavelet analyses and information theory using data from seven marshes. The results point to terrestrial groundwater level as a dominant control on redox variability across all sites. Because redox is a key driver of biogeochemical processes, and specifically oxidation of organic matter that sequesters carbon and maintains marsh elevation, these terrestrial influences are critical to understanding marsh function and evolution. The newly identified links between onshore groundwater levels and marsh redox conditions shift the traditional paradigm and suggest that terrestrial hydrology is a primary control on salt marsh carbon sequestration potential and resilience. This study investigates drivers of redox potential in several salt marsh sites on the basis of time series datasets. Wavelet and mutual information analyses show that the terrestrial groundwater level, rather than the marsh groundwater level, is the dominant control on redox potential.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"157-166"},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466311","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}

Although studies have explored the impacts of various extreme weather events on IPV, there is still inadequate evidence on the association between flood exposure and IPV on a multi-country or global scale. Therefore, we utilized the Demographic and Health Surveys database to examine this association on a multi-country scale and further explored modification effects of inequality outside and within the household. This study included 340,955 ever-partnered women from 31 low- and middle-income countries across Asia, Africa and Latin America. The results showed that flood exposure was associated with increased prevalence of total IPV (percentage difference 10.78%, 95% confidence interval 8.24–13.38%), physical violence (4.94%, 2.31–7.64%), sexual violence (13.03%, 8.61–17.62%) and emotional violence (17.62%, 14.28–21.06%). We found stronger flood–IPV associations among household with greater inequality. Our findings indicate additional harm associated with flood exposure for women in low- and middle-income countries, emphasizing the role of gender inequality under climate change. Flood exposure can increase the risk of intimate partner violence. Intra-household and societal gender inequalities can further exacerbate this vulnerability.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 3","pages":"296-306"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690316","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 industry is under intense scrutiny for widespread failure in its environmental performance, discharging 12.7 million monitored hours of untreated wastewater and sewage into English waterways between 2019 and the end of 2023. At the time of writing, multiple investigations by environmental and financial regulators are in progress, and regulatory oversight is under review by the recently formed Office for Environmental Protection. While limited monitoring hid the full extent of underperformance, we argue that the WaSCs have prolonged this environmental disaster through strategies that mirror those of other large polluting industries in the past. We test this hypothesis for the nine major WaSCs in England against a published framework of 28 ‘greenwashing/deception’ tactics of large industries. We identified 22 of these tactics that could be seen as disinformation, greenwashing and manufacturing doubt. The financial exploitation of water resources in England, alongside long-term degradation of infrastructure and ineffective regulation, raises globally important issues around water security, ethics and environmental stewardship. Much greater scrutiny of both industry performance and industry communication is required. In the past 5 years, a huge amount of untreated wastewater has been released into English waterways. An analysis of the communication used by the water utilities shows that they have employed strategies used by large polluting industries in the past, prolonging the consequences of this environmental disaster.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"231-243"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44221-024-00370-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466321","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}

Here we present a facile strategy for laboratory-scale mass production of Co-SACs with multidimensional coordination engineering, where atomically dispersed Co–N4 sites are spontaneously modulated by axial Cl and second-shell S (Co1CNCl/S). The configuration downshifts the d-band centre of active Co sites, enhances charge-transfer capacity and significantly strengthens the Co–O bond with peroxymonosulfate, forming a surface electrophilic intermediate with mild oxidation potential. Consequently, Co1CNCl/S steers peroxymonosulfate activation via a non-radical electron-transfer pathway, achieving selective phenol degradation within 5 min with a turnover frequency of 1.82 min−1, outperforming state-of-the-art catalysts. In a continuous flow, the Co1CNCl/S-packed column achieves effective organic wastewater treatment at just $US0.22 per tonne. This work demonstrates a scalable approach for developing cost-effective SACs for environmental remediation. Despite the considerable potential of single-atom catalysts in water and wastewater treatment, large-scale production is still challenging. A multidimensional coordination approach provides a practical and cost-effective method for the mass production of single-atom catalysts.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"211-221"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466320","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}

Boron is a trace contaminant that is ubiquitous in seawater and has been widely detected in groundwater. Current boron removal methods, such as multi-stage reverse osmosis and ion-exchange adsorption, are chemical and energy intensive, necessitating the development of more sustainable technologies. Here we address this challenge by developing surface functionalized microporous electrodes that enable boron-selective bipolar membrane-assisted electrosorption. Our study demonstrates that micropore functionalization with oxygen-containing (hydroxyl, lactone and carboxyl) and boron-selective (dopamine, 3-methylamino-1,2-propanediol and N-methyl-d-glucamine) functional groups substantially improves electrode performance for boron removal and selectivity. The functionalized electrodes exhibit a boron removal selectivity that is an order of magnitude higher than that of the pristine electrode, facilitating energy efficient boron electrosorption. We identify hydroxyl groups as the key factor in enhancing boron removal performance and selectivity during electrosorption. Molecular dynamics simulations demonstrate the underlying mechanisms of boron selectivity, highlighting the role of hydrogen bonding between hydroxyl groups and boron in governing the boron-selective electrosorption process. Boron removal is a persistent challenge in traditional desalination approaches. The functionalized microporous electrodes enable efficient boron removal with high selectivity in the electrosorption process.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 1","pages":"99-109"},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121635","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}

Theory and Earth system models (ESMs) suggest that stricter plant stomatal regulation under high CO2 will reduce transpiration, potentially boosting runoff. Yet, across a 12-member ensemble of idealized ESM simulations that isolate plant responses to CO2, we show that lower transpiration robustly enhances runoff over only 5% of modelled global land area. Precipitation changes are five times more important than transpiration changes in driving runoff responses and are a significant signal of CO2 physiological forcing over 31–57% of land areas across models. Crucially, ESMs largely disagree on where physiologically forced precipitation changes occur but agree that plant responses in most locations are as likely to reduce runoff as increase it. These results imply that large model uncertainties in precipitation responses, rather than transpiration responses, explain why ESMs disagree on plant physiologically driven runoff changes. This study shows that Earth system models disagree on the spatial distribution of plant-induced precipitation changes but indicate that plant responses are as likely to decrease runoff as they are to increase it under rising CO2.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"167-177"},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44221-024-00361-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466277","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}
