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.

过去和现在的采矿活动导致大片土地失去生产力，与此同时，曲海的采矿活动不断扩大，现场矿山复垦成本不断增加，以及人为造成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开发知识和技能，通过在贫瘠的采矿残留物沉积物中重新造林，使用树木和灌木代替广泛使用的草，从而增加温室气体（GHG）减排。我们的团队由务实的研究人员组成，他们在森林和矿山领域具有可持续发展、森林栽培、生命周期评估（LCA）、建模、生物技术和微生物学方面的专业知识。我们在过去3年里与我们的工业伙伴一起规划的多学科研究**在本提案中得到了综合，毫无疑问，这将是迄今为止将矿区生态恢复和温室气体减排联系起来的最综合的项目，如果不是全国的话。该项目为期3年，主要研究三个方面：1)利用再造林和有机修正方案评估植被和土壤对尾矿复垦的早期响应；2)量化尾矿复垦和有机修正替代方案的温室气体净平衡和减缓效率；3)分析A/R情景下采矿业温室气体排放补偿的短期和长期环境效率和成本效益。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。
