This award provides support to U.S. researchers participating in a project competitively selected by a 9-country initiative on global change research through the Belmont Forum. The Belmont Forum is a consortium of research funding organizations representing over 55 countries focused on support for transdisciplinary approaches to global environmental change challenges and opportunities. It aims to accelerate delivery of the international research most urgently needed to remove critical barriers to sustainability by aligning and mobilizing international resources. Each partner country provides funding for their researchers within a consortium to alleviate the need for funds to cross international borders. This approach facilitates effective leveraging of national resources to support excellent research on topics of global relevance best tackled through a multinational approach, recognizing that global challenges need global solutions. This award provides support for the U.S. researchers to cooperate in consortia that consist of partners from at least three of the participating countries. The research teams will work to identify sustainable pathways to help alleviate the increasing and unprecedented pressure on the natural resources that interact to provide sustainable life support systems and essential benefits to societies such as food production and water quality and quantity. The impacts of changes in land management and urbanization will be evaluated to develop sustainable soils and groundwater management options that will help create and maintain sustainable terrestrial ecosystems. The project aims to understand the hydrological, geochemical, geomorphological, microbiological, and socio-economic impacts of permafrost thaw to soils and surface/groundwaters in the Arctic and Subarctic, and their sustainability in the changing climate. The overall objective of the work is to compare sites in Siberia and Alaska with different permafrost characteristics (ice-rich Yedoma permafrost or carbon-rich permafrost peatland; continuous or discontinuous permafrost), climate-sensitivity, vegetation, and degradation types along latitudinal and longitudinal gradients. To accomplish this, the team will study several key small watersheds in Siberia and Alaska. Each study area was chosen based on its representativeness of the region and more importantly for comparative power across a broad range of permafrost, vegetation, and degradation types. The main objective is to analyze the differences and similarities between sites to better understand the variations of impacts. To understand and compare the impacts of permafrost degradation between the different sites, the team has defined several indicators of the vulnerability of soils, surface/ground waters: natural and anthropogenic stressors, permafrost conditions and degradation, hydrologic and aquatic chemistry, carbon cycle and microbial communities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为美国研究人员提供支持，这些研究人员通过贝尔蒙特论坛参与了由9个国家的全球变化研究倡议竞争性选择的项目。 贝尔蒙特论坛是一个由代表55个以上国家的研究供资组织组成的联合会，其重点是支持采取跨学科办法应对全球环境变化挑战和机遇。 它的目的是通过调整和调动国际资源，加快提供最迫切需要的国际研究，以消除可持续性的关键障碍。每个伙伴国家都在一个财团内为其研究人员提供资金，以减轻跨越国际边界的资金需求。这一办法有助于有效利用国家资源，支持对具有全球意义的专题进行出色的研究，最好通过多国办法加以处理，同时认识到全球挑战需要全球解决办法。该奖项为美国研究人员提供支持，使他们能够在由至少三个参与国的合作伙伴组成的联盟中进行合作。 研究小组将努力确定可持续的途径，以帮助减轻自然资源日益增加的前所未有的压力，这些自然资源相互作用，为社会提供可持续的生命支持系统和基本利益，如粮食生产和水质和数量。 将对土地管理和城市化方面的变化所产生的影响进行评价，以制定可持续的土壤和地下水管理办法，帮助建立和维持可持续的陆地生态系统。 该项目的目的是了解水文，地球化学，地貌，微生物和社会经济的影响，永久冻土融化的土壤和地表水/地下水在北极和亚北极，及其在不断变化的气候的可持续性。 这项工作的总体目标是比较在西伯利亚和阿拉斯加的网站与不同的永久冻土特征（冰丰富的Yedoma永久冻土或富碳永久冻土泥炭地;连续或不连续的永久冻土），气候敏感性，植被和退化类型沿着纬度和纵向梯度。为了实现这一目标，该团队将研究西伯利亚和阿拉斯加的几个关键小流域。每个研究区域的选择是基于其在该地区的代表性，更重要的是在广泛的冻土，植被和退化类型的比较权力。主要目的是分析不同地点之间的差异和相似之处，以更好地了解影响的变化。为了了解和比较不同地点之间永久冻土退化的影响，该小组确定了土壤、地表/地下沃茨脆弱性的几个指标：自然和人为压力，永久冻土条件和退化，水文和水生化学，该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识产权进行评估来支持。优点和更广泛的影响审查标准。
