Across Inuit Nunangat, critical infrastructure, navigation routes, homes, and food and water security in coastal communities are threatened by erosion, subsidence and related flooding. Amongst the most dramatic example of the challenges faced by Arctic communities is Tuktoyaktuk (also Tuktuyaaqtuuq), Northwest Territories, where the northwest portion of the Hamlet will potentially be lost due to coastal erosion within the next 20 years while additional areas will suffer increased flooding. The critical issues faced are varied and complex and their impacts both direct and indirect. Through close working relationships, recent research advances, and continued community discussions it became evident that many of the core problems center on changing ground conditions. For example, the loss of land through coastal erosion damages infrastructure, forces relocation, and releases hazardous material in the form of floating obstructions, sediment that blocks channels, and pollutants or chemicals from waste sites harmful to marine life. A warming climate has also resulted in accelerated degradation of permafrost and in particular ice within the ground. The resulting subsidence damages infrastructure and access routes, increases the likelihood of flooding, and turns a vegetated landscape into sprawling mud slump complexes that remove habitats and produce very dusty environments. The potential physical impacts of these changes on people are clear but the extent, timing, and future trends remain uncertain due to limited targeted and appropriate data. Additionally, the wider effects on mental health and on social, economic, and cultural wellbeing within the community are poorly understood. Therefore, strategic decision-making and effective mitigation and adaptation urgently require new sustainable (community-driven) solutions to changing ground conditions. The Nuna (Inuvialuktun for 'land', 'country' and 'soil') project draws together a diverse and interdisciplinary team that will provide new appropriate tools and solutions to mitigate and adapt to ground instability impacts. The dramatic and variable effects of changing ground conditions will be addressed through state-of-the-art solutions, transformative and transferrable approaches, and sustained, respectful and productive working relationships. Nuna will equip and train community climate monitors to develop new, significantly more accurate predictions of future erosion rates using 3D processing techniques, which we have already successfully piloted during the pandemic. Advanced ground survey approaches will produce the first subsidence vulnerability maps for current and planned settlement sites. New low-cost monitoring technologies will provide an early warning system for preventative action before damaging levels of change occur and assess the success of nature-based solutions to ground instability. Nuna will also provide new information on the real-time threats to health from air quality changes from new dust sources in the changing landscape and water-based threats such as driftwood or contaminants released during storm events. Running across these practical solutions to changing ground conditions Nuna will also determine which of the many potential cultural social, economic and health impacts need to be prioritized and work with residents to produce effective and culturally appropriate mitigation strategies. Through the meaningful co-production of all stages of the research process, the outcomes and enduring impacts of Nuna impacts will extend well beyond the communities directly involved.

在因努伊特努南加特，沿海社区的关键基础设施、航道、家园以及粮食和水安全受到侵蚀、沉降和相关洪水的威胁。北极社区面临的挑战中最引人注目的例子是西北地区的Tuktoyaktuk（也称Tuktuyaaqtuuq），在那里，哈姆雷特的西北部分可能会在未来20年内因海岸侵蚀而消失，而其他地区将遭受更多的洪水。所面临的关键问题多种多样，错综复杂，其影响既有直接的，也有间接的。通过密切的工作关系，最近的研究进展，并继续社区讨论，很明显，许多核心问题的中心不断变化的地面条件。例如，海岸侵蚀造成的土地损失破坏了基础设施，迫使人们搬迁，并以漂浮障碍物、阻塞水道的沉积物以及废物场产生的有害海洋生物的污染物或化学品的形式释放出有害物质。气候变暖还导致永久冻土，特别是地下冰的加速退化。由此产生的沉降破坏了基础设施和通道，增加了洪水泛滥的可能性，并将植被景观变成了庞大的泥浆塌陷复合体，从而消除了栖息地并产生了非常尘土飞扬的环境。这些变化对人类的潜在物理影响是明确的，但由于有限的针对性和适当的数据，其程度，时间和未来趋势仍然不确定。此外，对心理健康以及社区内的社会，经济和文化福祉的更广泛影响知之甚少。因此，战略决策以及有效的减缓和适应迫切需要新的可持续（社区驱动）解决方案来应对不断变化的地面条件。Nuna（Inuvialuktun代表“土地”、“国家”和“土壤”）项目汇集了一个多元化的跨学科团队，将提供新的适当工具和解决方案，以减轻和适应地面不稳定的影响。将通过最先进的解决方案、变革性和可转移的方法以及持续、相互尊重和富有成效的工作关系来解决不断变化的地面条件所产生的巨大和多变的影响。Nuna将装备和培训社区气候监测员，利用3D处理技术开发新的、更准确的未来侵蚀率预测，我们已经在疫情期间成功试用了该技术。先进的地面调查方法将为目前和计划中的定居点绘制第一张沉降脆弱性图。新的低成本监测技术将提供一个预警系统，以便在发生破坏性程度的变化之前采取预防行动，并评估以自然为基础的解决地面不稳定问题的办法是否成功。Nuna还将提供有关空气质量变化对健康的实时威胁的新信息，这些空气质量变化来自不断变化的景观中的新灰尘来源，以及风暴事件期间释放的浮木或污染物等水基威胁。通过这些实际的解决方案来改变地面条件，努纳还将确定许多潜在的文化社会，经济和健康影响中的哪些需要优先考虑，并与居民合作制定有效的和文化上适当的缓解战略。通过对研究过程的所有阶段进行有意义的共同制作，努纳影响的成果和持久影响将远远超出直接参与的社区。
