Sustainable Development and Democratic Resilience in the European Union

The European Union is increasingly confronted with a convergence of sustainability, democratic, and security-related challenges that affect the conditions for long-term transformation. While sustainable development and democratic resilience are often discussed separately, their interdependence has become more visible in the context of geopolitical instability, geoeconomic competition, hybrid threats, and growing societal polarization. This article examines the relationship between sustainable development and democratic resilience in the European Union and analyses how external pressures shape both agendas. The study employs a qualitative, concept-driven research design that combines the analysis of EU strategic and policy documents, a structured review of relevant scholarly literature, and triangulation with selected sustainability and governance indicators. The findings suggest that the implementation of sustainable development goals depends not only on regulatory and economic capacity, but also on social cohesion, public trust, and the resilience of democratic institutions, which together shape the legitimacy, continuity, and political feasibility of long-term transformative policies. At the same time, energy dependence, supply-chain vulnerabilities, technological dependencies, and information threats increasingly constrain the EU’s sustainability agenda. In response, the article proposes the concept of Sustainable Democratic Security as an analytical framework linking sustainability governance, democratic resilience, and strategic-security capacity. The article contributes to the literature by conceptualising these dimensions as mutually conditioning components of a common governance framework and by outlining their implications for integrated EU policymaking under conditions of geopolitical and geoeconomic pressure.
