Permafrost regions are undergoing rapid environmental changes, presenting significant engineering and scientific challenges that require interdisciplinary collaboration. As permafrost thaws, the stability of infrastructure such as roads, pipelines, and buildings is compromised, raising economic and safety concerns. Understanding these interactions between the natural environment and built infrastructure demands integration of geophysical monitoring, geotechnical engineering, modeling, and field research. This session brings together experts to discuss advancements, challenges, and solutions related to permafrost dynamics, infrastructure resilience, and sustainability. Key topics include permafrost monitoring and modeling, geophysical methods for detecting degradation, engineering solutions for infrastructure in thawing environments, impacts on hydrology and ecosystems, and remote sensing for tracking changes. The session also highlights the role of Indigenous knowledge and community-based adaptation strategies. We welcome a diverse group of participants, including scientists and engineers from all disciplines engaged in permafrost research.
