AbstractPermafrost thaw alters the stability of soils and consequently threatens the integrity and functioning of infrastructure and transportation networks that are of central importance to northern communities. Infrastructure in many of the IRIS 2 communities has already experienced extensive damage and costly repairs, as illustrated in selected case studies. Projected climate changes and maladapted infrastructure are likely to disrupt permafrost and the thermal stability of community lands, with significant implications for industrial and socio-economic development. Planning and managing sustainable infrastructure in areas with sensitive permafrost will require stakeholder participation in hazard assessment and cost-of-adaptation mapping to allocate resources in the most cost-effective manner. Regulatory frameworks and appropriate governance for infrastructure design and construction will be critical to ensuring safe and sustainable community development in the region.
