A just and green transition away from carbon-intensive economy will require large amount of critical earth mineral to support new technologies such as lithium battery and solar panels. Canada is uniquely positioned to support this green transition because of the vast number of mineral resources that are currently untapped. However, for these resources to be extracted sustainably, there is a need to consider the interdisciplinary, and cumulative impacts of natural resources development on socio-environmental system. Ecosystem services (ES) provide a pertinent approach to these considerations, as ES science provide tools and conceptual frameworks to investigate the provision of goods and services from nature to communities. Regional assessments, as described in the new 2019 Impact Assessment Act, provide a new, timely policy tool to ensure that interdisciplinary cumulative impacts are considered in impact assessments. Yet, based on the current states of ES science, there is a gap in the scientific literature for readily available scientific information to support regional assessments, especially regarding large-scale assessments of highly valued ES and associated baseline data. Understanding the gaps in ES provisioning in the context of cumulative impacts is crucial to support the sustainable development of natural resources in Canada. Drawing from my experience as a senior impact assessment officer and as a large-scale freshwater sustainability researcher, I want to initiate my research program at Memorial University by investigating how cumulative impacts related to natural resources developments affect the capacity of, demand for, and pressures on ES of Canadian watersheds at various scales. My work will focus on riverine services such as water provision for communities, recreational and subsistence fishing, recreational boating, flood protection, cultural and spiritual significance, and nutrient cycling. I will undertake research at the Canadian, regional (Atlantic Canada and Quebec), and local (Western Coast of Newfoundland) scales. The next five years of my research program will focus on the integration of interdisciplinarity by modelling identified highly valued riverine ES and on interscalability by comparing local and national scales ES modelling approaches and results. More specifically, I want to investigate current gaps in understanding in ES science by identifying tradeoffs (an increase in one service linked to declines in others), by assessing the cumulative impacts of natural resources development projects on ES provisioning, and by better understanding the influence of the scale of assessment on resulting ES interactions. Overall, combining ES and cumulative impacts modelling at regional and Canadian scales is a promising and novel avenue to ensure the sustainable management of socio-environmental systems at large scales.

从碳密集型经济向公正和绿色转型将需要大量关键的地球矿物来支持锂电池和太阳能电池板等新技术。加拿大具有支持这一绿色过渡的独特地位，因为该国拥有大量目前尚未开发的矿产资源。然而，为了可持续地开采这些资源，需要考虑自然资源开发对社会环境系统的跨学科和累积影响。生态系统服务（ES）为这些考虑提供了一个相关的方法，因为ES科学提供了工具和概念框架，以调查从自然界到社区的商品和服务的提供。 新的2019年《影响评估法》所述的区域评估提供了一种新的、及时的政策工具，以确保在影响评估中考虑跨学科的累积影响。然而，根据环境生态系统科学的现状，科学文献中存在着一个缺口，无法提供现成的科学信息来支持区域评估，特别是在对价值很高的环境生态系统和相关基线数据进行大规模评估方面。 了解在ES供应的背景下，累积影响的差距是至关重要的，以支持加拿大自然资源的可持续发展。从我的经验，作为一个高级影响评估官员，并作为一个大规模的淡水可持续性研究人员，我想开始我的研究计划，在纪念大学调查如何累积影响自然资源开发影响的能力，需求，和加拿大流域ES的压力在各种规模。我的工作将侧重于河流服务，如社区供水，娱乐和生计捕鱼，娱乐划船，防洪，文化和精神意义，以及营养循环。我将在加拿大，区域（大西洋加拿大和魁北克）和地方（纽芬兰西海岸）规模进行研究。 我的研究计划的未来五年将集中在跨学科的整合，通过建模确定高度重视的河流ES和interscalability通过比较地方和国家尺度ES建模方法和结果。更具体地说，我想调查目前的差距，在ES科学的理解，确定权衡（一个服务的增加与其他下降），通过评估自然资源开发项目对ES供应的累积影响，并通过更好地了解评估的规模对ES相互作用的影响。总的来说，在区域和加拿大的规模相结合的ES和累积影响建模是一个有前途的和新的途径，以确保可持续管理的大规模的社会环境系统。
