Problems of public administration in the context of global security transformations: Integrative review

The relevance of this study is driven by profound transformations in the global security environment, the intensification of geopolitical instability, the proliferation of hybrid threats, and the expansion of digital challenges, all of which significantly reshape the operating conditions of national public administration systems. The purpose of the study was to provide a comprehensive analysis of the impact of global security megatrends on public administration and to substantiate the agile approach as an effective governance response to contemporary challenges. The methodological basis of the study relied on an interdisciplinary review of academic sources and a conceptual synthesis of approaches from public administration, security studies, resilience theory, and adaptive governance. The paper analysed key global security megatrends, including digitalisation, globalisation, geopolitical shifts, economic disruptions, and hybrid threats, and identified their cumulative effects on the transformation of public administration paradigms. The findings demonstrated that conventional bureaucratic models are increasingly inadequate in environments characterised by high uncertainty, multidimensional risks, and rapid change. The study highlighted the growing importance of adaptability and resilience as core attributes of contemporary public administration. Drawing on international studies and empirical cases, including examples from Africa, Indonesia, and European countries, the analysis showed that agile public administration contributes to improved public service delivery, enhanced decision-making capacity, and greater institutional responsiveness to hybrid and geopolitical challenges. Agile governance was conceptualised as an integrative management model that combined digital transformation, cross-sectoral collaboration, and citizen-oriented service design. The practical significance of the study lies in its applicability to the development of public administration reform strategies and the implementation of agile governance approaches within public sector institutions operating under conditions of contemporary global security transformation
