Strategic Patterns of Green Infrastructure: Implications for Spatial and Urban Planning

Contemporary urban development imposes an increasingly pronounced need for aligned spatial transformations with the preservation of natural resources, adaptation to climate change, and the improvement of quality of life. In this context, the concept of green infrastructure has been recognized as an integrative framework that connects ecological processes with spatial and urban planning. However, the ways in which green infrastructure is strategically articulated and operationalized through planning processes vary depending on the institutional and spatial context. The aim of this paper is to identify the dominant strategic approaches to green infrastructure planning and to examine their implications for spatial and urban planning. The research is based on a qualitative comparative analysis of selected European green infrastructure strategies, while the Green Infrastructure Strategy of the City of Belgrade is considered as an analytical case study within the specific institutional and planning context of Serbia. The analysis focuses on three key components of strategic articulation—visions, objectives, and measures—in order to identify recurring patterns that shape the integration of green infrastructure into planning practice. The results indicate a high degree of convergence among strategic approaches, particularly regarding the emphasis on quality of life, ecosystem services, biodiversity conservation, and the strengthening of climate resilience. The identified patterns indicate the need for transformation of regulatory frameworks, the improvement of planning procedures and instruments, and the adoption of a spatial logic based on connectivity and multifunctionality. The analytical examination of the Belgrade Strategy shows that its structure of visions, objectives, and measures encompasses the key regulatory, procedural, and spatial prerequisites for incorporating green infrastructure into planning practice, and at the same time, its operationalization depends on institutional capacities, information systems, financial instruments, and mechanisms of intersectoral coordination. The paper concludes that green infrastructure strategies play an important role in mediating between public policies and spatial planning solutions, while their effectiveness depends on the alignment of regulatory, procedural, and spatial instruments.
