Landscape carbon accumulation through reductions in emissions (L-CARE): developing brownfield management protocols for carbon sequestration and habitat use

棕地管理是碳(C)封存和储存的重要机会，有助于实现工业气候变化减缓目标。陆地生物圈中的碳含量是大气中的四倍，但缓解气候变化的传统生态系统管理可能存在争议。本研究计划的目的是量化安大略省最大的采矿和冶炼中心的大规模硫和金属减排，加上新的生态系统开垦实践，如何导致碳封存并影响初级生产、矿化以及通过生态系统的碳和能量转移的潜在过程。该研究项目将为我们的合作伙伴淡水河谷和萨德伯里-伊诺（嘉能可）提供重要的经济和环境机会。我们初步估计，与未开垦的土地相比，经管理的萨德伯里高地的30摄氏度储存潜力为500万吨，相当于约5亿美元。然而，与其他碳封存计划相比，我们研究的一个独特而重要的焦点是碳库之间的流域联系，认识到碳不是静态的，而是在高地、湿地和湖泊（景观受体）与大气之间不断交换的。我们将重点关注高地、湿地和湖泊系统及其联系，数据将提供给一个规模和整合团队，该团队将使用遥感方法和综合会计方法将试验地块扩大到景观规模，以预测未来的碳封存潜力。这项工作还将作为一套重要的案例研究，指导安大略省和加拿大其他地方棕地环境的工业管理，以实现碳封存。该研究项目将为复杂工业景观中碳和温室气体循环和管理的应用和基础方面提供良好的培训环境，促进hqp与行业和政府合作伙伴以及8所大学、2家合作伙伴和2家合作公司、3家政府机构的共同申请者和合作伙伴的互动，并使用从基因到领域到景观（建模）尺度的多学科方法。

Brownfield management represents an important opportunity for carbon (C) sequestration and storage to helpmeet industrial climate change mitigation targets. C is four times more plentiful in the terrestrial biosphere thanin the atmosphere, but conventional ecosystem management for climate change mitigation can be controversial.The OBJECTIVE of this research program is to quantify how massive sulfur and metal emissions reductions inOntario's largest mining and smelting centre, coupled with novel ecosystem reclamation practices, lead to Csequestration and influence the underlying processes of primary production, mineralization, and C and energytransfer through ecosystems. This research program will facilitate important economic and environmentalopportunities for our partners, Vale and Sudbury-INO (Glencore). Our preliminary estimate of 30y C storagepotential in managed Sudbury uplands relative to un-reclaimed lands is 5Mt representing ~$500 million.However a unique and important focus of our study relative to other C sequestration initiatives is onwatershed linkages between C pools, recognizing that C is not static, but continuously exchanging betweenuplands, wetlands and lakes (the landscape receptors) and the atmosphere. We will focus on upland, wetland,and lake systems and their linkages and the data will feed to a scaling and integration team, who will useremote sensing approaches and integrative accounting approaches to scale up trial plots to landscape scales toproject future C sequestration potentials. This work will also serve as an important set of case studies to guideindustrial management of brownfield environments for C sequestration elsewhere in Ontario and Canada.The research program will provide an excellent training environment for both applied and fundamentalaspects of C and GHG cycling and management across complex industrial landscapes, facilitating HQPinteractions with industry and government partners and with co-applicants and partners across 8 universities, 2partner and 2 collaborator companies, 3 government agencies and by using multidisciplinary approachesspanning from the gene-to-field-to-landscape (modelling) scales.
