MIDST-CZ: Maximising Impact by Decision Support Tools for sustainable soil and water through UK-China Critical Zone science

英国和中国的这一合作项目提议将建立一套决策支持工具(DST)，其中纳入正在进行的英国-中国临界区科学研究计划第一阶段的知识进步。有了这些进步，目前在英国和中国使用的DST将被改编、扩展、测试和应用。DST、数据集和决策成果将指导和评估特定地点的水土管理创新，并创建路线图，将影响成果和计划扩大到中国的区域和全国范围。该项目将整合第一阶段资助的5个项目的团队和研究成果。第二阶段将提供决策支持方法及其应用方面的即时创新，以及实现长期影响和官方发展援助成果的途径：恢复生态系统、改善土壤肥力和水质、改善农业生计以及改善粮食和水安全。影响交付将集中在第一阶段建立的中国的5个临界区观测站(CZO)，这些观测站位于与土壤和水资源退化有关的大规模环境和经济挑战地区。1.中国西南的水文岩溶CZO--与输导性碳酸盐盐岩地区含水层和地表水的营养污染有关的土地利用和水质2.长江三角洲城市周边CZO--城市大气沉积和农用化学品强化使用造成的土壤污染。中国西南喀斯特CZO--生态系统退化和喀斯特荒漠化与土壤侵蚀和土壤肥力损失有关4.红壤CZO--集约化农业生产造成的土壤肥力损失5.黄土CZO--农村土地利用集约化下的生态系统退化中国与利益攸关方共同开展的一项研究将确定CZO所在地区需要解决的土地、水和粮食需求冲突。这种知识工程旨在避免科学家将数字科学技术概念化的方式与利益相关者如何最有效地使用数字科学技术之间公认的不匹配。最近关于土地、水和粮食可持续性的数字科学技术的综述为评估不同数字科学技术对中国挑战的适宜性提供了一个平台。英国和中国团队和利益相关者将确定最有前景的DST方法，并使用5个CZO的数据集进行测试。将在更广泛的DST用户和潜在用户中对这些产出进行测试。结果将使测绘DST及其适宜性，以应对5个CZO地点的土壤和水管理挑战。这项工作将评估现场各利益攸关方群体感兴趣的范围内DST的有效性。这将包括确定可持续的做法、CZO和相关测量在多大程度上加强证据基础并为管理决策提供做法信息，以及采用DST方法将如何改善特定地点的应用。该项目将应用关于土壤和水资源需求和使用模式的地理变异性以及地质、土壤、植被覆盖、气候和天气的自然条件的国家数据集。通过与区域规划者接触，该项目将设计路径，扩大数字科学技术成果的规模，以便应用于区域规模的资源规划。最后一个阶段将是将经过调整、应用和扩大的数字科学技术方法综合成实用指南，指导如何在区域具体情况下部署数字科学技术、不同数字科学技术的能力和数字科学技术产出的适用性。中国的机构合作伙伴将发布指导意见，组织将被确定为超级用户并进行培训，以传播培训。超级用户将在中国合作伙伴的带领下，在中国举办一系列区域研讨会，打造走在水土管理规划和实施创新前沿的用户网络。

This collaborative UK-China project proposes will establish a suite of Decision Support Tools (DSTs) that incorporate knowledge advances from the ongoing Phase 1 UK-China Critical Zone science research programme. With these advances, DSTs currently used in the UK and China will be adapted, expanded, tested and applied. The DSTs, data sets and decision outcomes will guide and evaluate site-specific innovation in soil and water management, and create roadmaps to scale up impact outcomes and plans to regional and national scale in China. The project will integrate the teams and research results of the 5 projects funded in Phase 1. Phase 2 will deliver immediate innovation in decision support methods and their application, and pathways to long-term impact and ODA outcomes: to restore ecosystems, improve soil fertility and water quality, improve farming livelihoods and improve food and water security. Impact delivery will focus on 5 critical zone observatories (CZOs) in China, established in Phase 1, which are located in regions with large-scale environmental and economic challenges related to degraded soil and water resources. 1. Hydro Karst CZO in SW China - land use and water quality linked to nutrient contamination of aquifers and surface waters in transmissive carbonate terrain2. Peri-Urban CZO in the Yangtze delta - soil contamination from urban atmospheric deposition and intensification of agricultural chemical use3. SPECTRA Karst CZO in SW China - Ecosystem degradation and karstic desertification linked with soil erosion and loss of soil fertility 4. Red Soils CZO - loss of soil fertility from intensification of agricultural production5. Loess CZO - ecosystem degradation under intensification of rural land useParticipatory research with stakeholders in China will identify the land, water and food demand conflicts that need be addressed in the regions of the CZOs. This KE is designed to avoid a recognised mismatch between the way DSTs are conceptualised by scientists and how DSTs may be most effectively used by stakeholders. Recent reviews of DSTs for land, water and food sustainability provide a platform for assessing the suitability of different DSTs to the challenges of China. The UK and China teams and stakeholders will identify the most promising DST approaches and test these using the data sets of the 5 CZOs. The outputs will be tested with a wider set of DST users and potential users. The outcomes will allow mapping DSTs and their suitability to address soil and water management challenges at the 5 CZO sites. This work will assess effectiveness of the DSTs across the scales of interest for stakeholder groups at the sites. This will include identifying sustainable practices, the scale at which the CZO and related measurements strengthen the evidence base and inform practices for management decisions, and how adaptations in a DST methodology would improve site-specific application. The project will apply national data sets on the geographic variability of soil and water resource demand and use patterns, and natural conditions of geology, soil, vegetation cover, climate and weather. Through engagement with regional planners, the project will design pathways to scale up the DST outcomes for application in regional-scale resource planning. The final stage will be synthesis of the adapted, applied and upscaled DST methods into practical guidance in how to deploy the DSTs in regionally specific contexts, the capabilities of different DSTs and applicability of DST outputs. The institutional partners in China will publish the guidance and organisations will be identified and trained as superusers to disseminate training. Superusers will conduct a series of regional workshops in China, led by Chinese partners, to create a network of users who are at the forefront of innovation in soil and water management planning and implementation.
