Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. The Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems, natural environment, and built environment in the following NNA areas: Arctic Residents, Data and Observation, Forecasting, Global Impact, and Resilient Infrastructure. Seasonality shifts, thawing permafrost, and the occurrence of extreme weather conditions in the Arctic today have led to cascading effects in the natural and human worlds. Plants and animals are changing their seasonality and ranging patterns. These changes put increased pressure on livelihoods of peoples of the North, whose dependence on the natural world is tied to weather and seasonality. Globalization, such as the growing presence of industrial and urban centers, also impacts the Arctic tundra and livelihoods of Indigenous peoples as never before. By considering impacts of multiple climatic and socioeconomic drivers on the functioning of an increasingly industrialized Arctic region, this project crystalizes processes that are or represent potential threats to the well-being of Arctic communities relying on reindeer herding economy. This project co-produces knowledge with various stakeholders representing the Indigenous community, regional government, and industry sectors. The project links numerous disciplines and provides training opportunities for the next generation of scientists as well as broader exposure via an inter-institutional course-forum and public outreach events.The goal of this project is to understand how the natural, social, and built environment systems within a tundra region are linked in their responses to stressors. This project examines how (1) tall vegetation impacts animals and reindeer herders, and feedback mechanisms conditioned on human activities; (2) changing snowpack influences food webs and animal population dynamics, and alters decision-making by reindeer herders and other stakeholders; (3) the built environment affects the reindeer herding system, as well as interactions between industrial workers and indigenous people and perceptions of the environment by these groups; and (4) reindeer management, social institutions, and markets for reindeer products affect community resilience, indigenous traditions and practices, and landscape structure. The Yamal region of Russia is an ideal site as it spans four of the five Arctic bioclimatic subzones and has an unprecedented large-scale survey of Yamal in the late 1980s as well as voluminous Soviet-era anthropological research on reindeer herders. This project works with regional stakeholders to test hypotheses of multi-system responses to changes in summer and winter heating, growing presence of industrial activities, and increasing social complexities in peoples of the North.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.

NSF的10个大创意之一是导航新北极（NNA）。 NNA项目应对北极快速变化的融合科学挑战。需要进行北极研究，以告知国家，较大地区和全球的经济，安全和弹性。 NNA赋予从本地量表到国际规模的新研究伙伴关系，使下一代北极研究人员多样化，加强了正规和非正式教育方面的努力，并在适当的情况下整合了知识的共同生产。该奖项通过解决以下NNA领域的社会系统，自然环境和建筑环境之间的互动来实现这一目标的一部分：北极居民，数据和观察，预测，全球影响和弹性基础设施。当今北极的季节性变化，融化多年冻土以及极端天气状况的发生导致自然和人类世界的层叠作用。动植物正在改变其季节性和范围的模式。这些变化给北方人民的生计带来了加大压力，他们对自然世界的依赖与天气和季节性有关。全球化，例如工业和城市中心的日益存在，也影响了以前从未有过的土著人民的北极苔原和生计。通过考虑多个气候和社会经济驱动因素对日益工业化北极地区运作的影响，该项目将依赖驯鹿畜牧经济的北极社区福祉的过程结晶或代表了对北极社区福祉的潜在威胁。该项目与代表土著社区，地区政府和行业的各种利益相关者共同培育知识。该项目将众多学科联系起来，并为下一代科学家提供培训机会，并通过机构间的课程和公共宣传活动更广泛的接触。该项目的目的是了解苔原地区内的自然，社交和建造环境系统如何与他们的压力响应联系起来。该项目研究了（1）高植被如何影响动物和驯鹿牧民，以及以人类活动为条件的反馈机制； （2）改变积雪会影响食物网和动物种群动态，并改变驯鹿牧民和其他利益相关者的决策； （3）建筑环境会影响驯鹿放牧系统，以及工业工人与土著人民之间的互动以及这些群体对环境的看法； （4）驯鹿管理，社会机构和驯鹿产品市场会影响社区的韧性，土著传统和实践以及景观结构。俄罗斯的雅马尔地区是理想的地点，因为它涵盖了五个北极生物气候子区中的四个，并且在1980年代后期对雅马尔进行了前所未有的大规模调查，以及大量的苏联苏联人类学研究。该项目与区域利益相关者合作，以测试多系统对夏季和冬季供暖变化的反应的假设，工业活动的日益增长的存在以及北部人民的社会复杂性的增加。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力功能和广泛的影响来评估Criteria criteria criteria criteria criteria criteria criteria。
