Afforestation/reforestation for the sustainable mineland reclamation and greenhouse gas management in the Canadian mining sector

过去和现在的采矿活动导致大片土地成为非生产性土地，再加上魁北克不断扩大的采矿活动，矿山开垦成本的增加，以及人类活动导致的前所未有的全球变暖危机。该项目旨在与采矿业合作伙伴一起，利用乔木和灌木而不是广泛使用的牧草，通过对贫瘠的采矿残渣再造林来提高温室气体减排的知识和技能。我们的团队由在可持续发展、森林培育、生命周期评估(LCA)、建模、生物技术和微生物学方面具有专业知识的林业和矿业部门的务实研究人员组成。我们在过去三年**与我们的工业合作伙伴计划的多学科研究**在本提案中进行了综合，无疑将是迄今为止将矿场生态恢复和温室气体缓解联系在一起的最完整的项目，即使不是在全国范围内也是如此。在这个为期三年的项目中，将涉及三个研究主题：1)评估植被和土壤对重新造林和有机改良剂方案的早期响应；2)量化尾矿复垦和有机改良剂替代方案的温室气体净平衡和缓解效率；3)分析采矿行业温室气体排放抵消的A/R方案的短期和长期环境效率和碳/财务平衡的成本效益。该项目还将为七名本科生和研究生以及一名博士后提供特殊的培训机会，从而有效地向我们的采矿合作伙伴转让技术。

Past and present mining activities result in vast expanses of land being made unproductive, which combines with expanding mining activities in Québec, the increasing costs of site mine reclamation, and the anthropogenically-driven crisis of global warming of unprecedented proportion. This project aims to develop, alongside mining industry partners, the knowledge and know-how to increase greenhouse gas (GHG) emission reductions through the reforestation of barren mining residue deposits, using trees and shrubs instead of the widely-used grasses. Our team is composed of practical-minded researchers with expertise in both the forest and mine sectors on sustainable development, silviculture, life cycle assessment (LCA), modelling, biotechnology and microbiology. The multidisciplinary research we have been planning over the last 3 years**with our industrial partners is synthesized in the present proposal and will undoubtedly be the most integrated project to date linking mine site eco-rehabilitation and GHG mitigation provincially, if not nationally. Three research themes will be addressed during this 3-year long project: 1) Evaluating the early response of vegetation and soils to mine tailings reclamation using scenarios of reforestation and organic amendments; 2) Quantifying the net GHG balance and mitigation efficiency of alternative scenarios of mine tailings reclamation and organic amendments; 3) Analysing the short and long terms environmental efficiency and cost-benefit of both carbon and financial balances of A/R scenarios for the GHG emission offset of mining industries. The project will also provide an exceptional training opportunity for seven undergraduate and graduate students, as well as a postdoctoral fellow, leading to effective technology transfer to our mining partners.
