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

这一中英合作项目将建立一套决策支持工具（DST），其中包括正在进行的第一阶段中英临界区科学研究计划的知识进步。随着这些进展，目前在英国和中国使用的DST将被调整，扩展，测试和应用。DST、数据集和决策结果将指导和评估土壤和水管理方面的特定地点创新，并创建路线图，以扩大影响成果和计划，并将其扩展到中国的区域和国家规模。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。第二阶段将在决策支持方法及其应用方面提供即时创新，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，提高土壤肥力和水质，改善农业生计，提高粮食和水安全。影响交付将侧重于第一阶段在中国建立的5个关键区域观测站（CZO），这些观测站位于土壤和水资源退化相关的大规模环境和经济挑战区域。1.中国西南部的水文岩溶CZO--与渗透性碳酸盐地形中含水层和地表沃茨营养污染有关的土地利用和水质2。长江三角洲城市周边的CZO-城市大气沉降和农业化学品使用的加剧对土壤的污染3。SPECTRA喀斯特CZO在中国西南部-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4。红壤CZO -农业生产集约化造成的土壤肥力损失5.黄土高原-农村土地利用加剧下的生态系统退化与中国利益相关者的对比研究将确定黄土高原地区需要解决的土地、水和粮食需求冲突。该KE旨在避免科学家对DST进行概念化的方式与利益相关者如何最有效地使用DST之间公认的不匹配。最近对土地、水和粮食可持续性DST的审查为评估不同DST对中国挑战的适用性提供了一个平台。英国和中国的团队和利益相关者将确定最有前途的DST方法，并使用5个CZO的数据集进行测试。将在更广泛的DST用户和潜在用户中测试这些产出。结果将允许映射DST及其适用性，以解决土壤和水管理的挑战，在5个CZO网站。这项工作将评估DST在各地点利益相关者群体利益范围内的有效性。这将包括确定可持续的做法，CZO和相关测量加强证据基础和为管理决策提供信息的做法的规模，以及DST方法的调整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、气候和天气等自然条件的国家数据集。通过与区域规划者的接触，该项目将设计扩大DST成果的途径，以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、应用和升级的DST方法综合成关于如何在区域具体情况下部署DST、不同DST的能力和DST产出的适用性的实用指南。中国的机构合作伙伴将发布指南，并将确定和培训组织作为超级用户，以传播培训。超级用户将在中国举办一系列区域研讨会，由中国合作伙伴领导，以建立一个处于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.
