While assimilation’s effects on language and identity are well documented, its consequences for pastoral learning systems, household governance, and adaptive capacity remain less systematically analysed. Drawing on interdisciplinary research, policy documents, and testimonies to the Norwegian Truth and Reconciliation Commission, the article provides a thematic synthesis of how state rationalization, educational restructuring, and administrative standardization have reconfigured Sámi Indigenous pastoral knowledge. The analysis shows that assimilation operates through governance mechanisms that translate Sámi professional language, siida-based organization, gendered earmark rights, and place-based ecological knowledge into standardized administrative categories. Reforms introduced from the 1970s onward privileged equilibrium-oriented and production-based indicators, marginalizing flexible, mobility-centered pastoral logics. Over time, these governance transformations have interacted with globalization, infrastructural expansion, land fragmentation, and climate change, intensifying pressures on seasonal mobility, pasture access, and the annual cycle central to nomadic pastoral adaptation. These processes have weakened intergenerational knowledge transmission, narrowed learning arenas, and redefined land-use competence as regulatory compliance rather than adaptive navigation of variable socio-ecological systems. Under accelerating climate change and land-use fragmentation, the resilience of Sámi reindeer husbandry depends on restoring coherence between language, mobility, household-siida organization, and practice-based learning. The article argues that seanadit, reconciliation grounded in institutional and epistemic realignment, is a prerequisite for robust pastoral governance in the Circumpolar North.
