Depopulation and Sustainable Territorial Governance: A Multilevel Analysis of Strategic Response Patterns in Poland

Depopulation constitutes a fundamental challenge for territorial governance, particularly within the framework of sustainable development; however, its representation in local strategic documents remains insufficiently explored. This study aims to identify and compare strategic responses to depopulation across two contrasting Polish regions—Dolnośląskie Voivodeship and Podlaskie Voivodeship—and three governance levels: regional, county, and municipal. An abductive mixed-methods approach was applied, combining discourse analysis with latent semantic analysis (LDA), and principal component analysis (PCA). The findings reveal a clear dominance of the pro-growth paradigm, while the adaptive approach associated with managed shrinkage remains marginal. Regional differences are primarily observed in problem framing—functional in Dolnośląskie and demographic in Podlaskie—but these distinctions do not significantly affect the types of policy responses. Structural instruments, particularly those related to consolidation, prevail, whereas functional and competency-based measures are less prominent. The results suggest the existence of a standardized model of strategic response to depopulation across regions and governance levels. This indicates limited diversification of policy approaches and highlights the need to more fully integrate adaptive strategies into territorial policy, especially in the context of long-term demographic change.
