Systems Water Management Framework for Catchment Scale Processes (CASYWat)

最近公布的《二十五年环境规划》认识到，必须把环境作为规划和发展的核心，为人们创造更美好的生活和工作场所。它的支持性证据突出表明，需要对水环境管理采取更基于系统的方法，并且需要更好地了解水系统的复杂性，包括它们与土地管理和利用的相互作用。在25YEP中，由环境局（EA）领导的坎布里亚流域先锋旨在测试整体河流流域环境管理的新治理模式，这被认为是成功实施自然资本核算的关键促成因素。坎布里亚流域先锋项目面临的主要挑战包括水资源可用性、质量和洪水风险管理、土地管理、游客和农村经济以及栖息地减少之间复杂的相互作用。因此，只有认识到更广泛的水环境利用和优先事项，并在利益相关者及其利益之间更加协调一致地开展工作，才能取得重大进展。在与EA及其广泛的利益相关者的合作下，该项目将应用系统思维和系统方法来理解、构建和测量坎布里亚先锋的集水区水系统复杂性。它将开发一个新的集水区规模过程系统水管理框架（CASYWat），该框架将指导和支持支撑第25集水区规模过程的关键概念的实际解释和演示。框架将定义系统的组件、这些组件之间的关系，以及集成这些元素的共享元模型。这将使复杂的沟通，并由利益相关者理解，使他们能够制定一个共同的目标和集体战略，在坎布里亚流域综合管理，并从事有效的决策。这项工作为期12个月，Mijic博士80%的工作时间将作为环境评估的一部分。工作计划包括三个阶段，即：（S1）如何处理集水区水管理系统的复杂性？这一阶段将把汇水管理纳入系统思维环境，映射参与坎布里亚先锋水管理决策的关键利益相关者的个人关注点，并开发汇水管理系统的个人感知模型；（S2）如何整合各组成部分来描述集水区水管理系统？这一阶段将开发系统的共享元模型和CASYWat框架的原型版本；（S3）如何使用已开发的框架来分析系统和评估其表现？这一阶段将使用S1中定义的Cumbia Pioneer案例研究，以及地图系统和其他评估工具（包括环境建模、系统动力学和自然资本评估）来测试CASYWat框架的适用性，这些工具可用于量化S2中定义的成功措施。该项目将以申请人早期的工作为基础。Mijic博士在复杂水系统的过程理解、高级建模和分析方面有着良好的记录。她的NERC资助的集水区水管理项目（NE/I022485/1和NE/N01670X/1）的成果将直接用于安置。她还将利用她在城市水管理系统方法（气候KIC蓝绿色梦想）和基础设施项目的环境风险方面的专业知识，这些项目是与多个合作伙伴合作交付的，包括EA和伦敦巴尼特自治市（NE/ m008161 /1）和泰晤士水务公司（NE/M008312/1）。最后，这项工作将与最近授予的NERC RISE项目赠款（CAMELLIA）密切相关，Mijic博士正在领导城市规模过程系统水管理框架（USYWat）的开发。

The recently released 25 Year Environment Plan recognises the need to put the environment at the heart of planning and development to create better places for people to live and work. Its supporting evidence highlights the need for taking a more systems based approach to water environment management, and the need for better understanding of complexity across water systems, including their interaction with land management and use. Within the 25YEP, the Cumbria Catchment Pioneer led by the Environment Agency (EA) is aimed at testing new governance models for the environmental management of river catchments as a whole, which is assumed to be a key enabler for the successful implementation of the natural capital accounting. The key challenges within the Cumbria Catchment Pioneer include complex interactions between water availability, quality and flood risk management, land management, visitor and rural economy and habitat decline. Therefore, significant progress will only be made by recognising wider water environment uses and priorities, and working more coherently across stakeholders and their interests. In collaboration with the EA and their wide range of stakeholders, this project will apply systems thinking and systemic approaches to understanding, structuring and measuring the catchment water system complexity of the Cumbria Pioneer. It will develop a novel Systems Water Management framework for Catchment Scale Processes (CASYWat) that will guide and support practical interpretation and demonstration of the key concepts underpinning the 25YEP. The framework will define the components of the system, relationships between these components, and a shared meta-model that integrates these elements. This will enable the complexity to be communicated to, and understood by the stakeholders, so that they can develop a shared purpose and collective strategy for integrated catchment management in the Cumbrian context, and engage in effective decision-making. The work is proposed as a 12-months placement with Dr Mijic working 80% of time as part of the EA. The work programme consists of three stages (S), namely: (S1) How to approach complexity in a catchment water management system? This stage will put catchment water management into systems thinking context, map individual concerns of key stakeholders involved in the Cumbria Pioneer water management decisions and develop individual perceptual models of the catchment water management system; (S2) How to integrate the components to describe a catchment water management system? This stage will develop a shared meta-model of the system and a prototype version of the CASYWat framework; (S3) How to use the developed framework to analyse the system and assess its performance? This stage will test the applicability of the CASYWat framework using the Cumbia Pioneer case studies defined in S1, and map systems and other assessment tools (including environmental modelling, system dynamics and natural capital assessment) that can be used to quantify Measures of Success defined in S2.The project will build strongly upon earlier work of the applicant. Dr Mijic has a strong track record of process understanding, advanced modelling and analysis of complex water systems. The outcomes from her NERC funded catchment water management projects (NE/I022485/1 and NE/N01670X/1) will feed directly into the placement. She will also draw upon her expertise in systems approach to urban water management (Climate KIC Blue Green Dream) and the Environmental Risks to Infrastructure projects that were delivered in collaboration with multiple partners, including the EA and the London Borough of Barnet (NE/M008169/1) and Thames Water (NE/M008312/1), respectively. Finally, the work will be strongly linked with the recently awarded NERC RISE programme grant (CAMELLIA), where Dr Mijic is leading the development of the Systems Water Management Framework for Urban Scale Processes (USYWat).
