A global survey showed that nearly 10 million people could die each year as a result of antimicrobial resistance (AMR) if the situation is left unchanged. The UK is at the forefront of the global fight against AMR and setting the vision to contain and control AMR by 2040. With reference to the World Health Organisation (WHO) AMR action plan, the global AMR surveillance programme is conducted to understand trends, monitor interventions and develop empiric treatment guidelines for AMR. However, in the water sector, this AMR surveillance effort mainly focuses on conventional treatment stages and does not include nature-based solutions (NbS) infrastructures. Defra's 25-Year Environment Plan, the Water Industry's National Environment Programme, and the Environment Agency 2025 Plan have created a unique opportunity to consider constructed wetlands (CWs) as NbS to deliver wastewater treatment with the provision of environmental and societal co-benefits. All water utilities have deployed their strategies to further promote CWs in sewage works. Therefore, understanding if CW, as an emerging preferred green approach for tertiary treatment in wastewater treatment plants, can act as the final safeguard of natural waters to mitigate such risks while maintaining the contribution of co-benefits is crucial.The experience and lessons learned from the global AMR action could significantly facilitate the current missing NbS focus area on AMR surveillance. Partner Prof Walsh has worked with the WHO on the AMR surveillance programme and the European Joint Programme with a specific focus on AMR. Her expertise and experience will strengthen this project team with key knowledge of the occurrence, transmission, and removal mechanisms of AMR. The AMR investigation in NbS is recently getting attention but suffers from a lack of international-scale assessment with a limited dataset. Partner Dr Carvalho is working on the EU NATURE project to evaluate AMR removal in different CWs from mainland Europe, and the findings will be shared with this project.In this project, PI Dr Lyu will conduct the first field survey in the UK to collect evidence from four different applied CWs in England and Wales with the support of two industrial partners (Anglian Water and Welsh Water). Together with available datasets from the literature and the project partners' network, this project will conduct an international comparative study of AMR removal in CWs as NbS for wastewater treatment. Moreover, the team will also assess the undervalued contribution of reactive oxygen species and indicate adaptations of CWs toward promoting rhizosphere-activated free radicals to oxidise AMR. Ultimately, this project aims to establish a unique collaborative partnership between international academics and industrial practitioners, through sharing experiences, discovering knowledge gaps, exploring technology innovation, and supporting evidence-based policymaking, toward developing a resilient wastewater treatment infrastructure based on NbS to mitigate the spread of AMR.

一项全球调查显示，如果情况不变，每年可能有近1000万人死于抗菌素耐药性（AMR）。英国站在全球抗击AMR的最前沿，并制定了到2040年遏制和控制AMR的愿景。参照世界卫生组织（WHO）AMR行动计划，开展全球AMR监测计划，以了解趋势、监测干预措施并制定AMR经验性治疗指南。然而，在水行业，AMR监测工作主要集中在传统处理阶段，不包括基于自然的解决方案（NbS）基础设施。Defra的25年环境计划，水行业的国家环境计划和环境局2025计划创造了一个独特的机会，将人工湿地（CWs）视为NbS，以提供环境和社会共同利益的污水处理。所有水务机构均已部署策略，进一步推广污水处理厂的化学废物。因此，了解CW作为污水处理厂三级处理的新兴首选绿色方法，是否可以作为天然沃茨的最终保障，以减轻此类风险，同时保持共同利益的贡献是至关重要的。从全球AMR行动中吸取的经验和教训可以显着促进目前缺少的NBS重点领域AMR监测。合伙人沃尔什教授曾与世卫组织合作开展AMR监测项目和欧洲联合项目，特别关注AMR。她的专业知识和经验将加强该项目团队对AMR发生，传播和清除机制的关键知识。NbS的AMR调查最近受到关注，但缺乏国际规模的评估，数据集有限。合伙人Dr Carvalho正在欧盟NATURE项目中评估来自欧洲大陆的不同化学武器对AMR的去除效果，并将结果与该项目分享。在该项目中，PI Dr Lyu将在两个工业合作伙伴（Anglian Water和Welsh Water）的支持下，在英国进行首次实地调查，收集英格兰和威尔士四种不同化学武器的证据。结合文献和项目合作伙伴网络中的可用数据集，该项目将对作为废水处理的NbS的CW中AMR去除进行国际比较研究。此外，研究小组还将评估活性氧的贡献被低估，并指出CW对促进根际激活的自由基氧化AMR的适应性。最终，该项目旨在通过分享经验，发现知识差距，探索技术创新和支持循证决策，在国际学术界和工业界从业者之间建立独特的合作伙伴关系，以开发基于NbS的弹性污水处理基础设施，以减轻AMR的传播。
