Initiative "Grünes Gallustal" St.Gallen

Grünes Gallustal serves as a pioneering framework to advance sustainability and enhance the quality of life in the city of St. Gallen, Switzerland. Developed through a bottom-up approach led by civil society, this initiative presents 14 carefully designed planning measures aimed at climate adaptation, biodiversity enhancement, and urban improvement. The measures range in complexity, from small-scale interventions such as tree planting and the reversal of soil sealing, to larger urban projects, including watercourse restoration and highway capping. Each measure is supported by clear, measurable sub-objectives. This 1,500-page blueprint is the outcome of a three-year, interdisciplinary collaboration involving 20 experts, incorporating rigorous scientific analyses, climate maps, and detailed before-and-after visualizations thus offering the public tangible perspectives on the city’s potential. Initial pilot projects in the city’s east, such as the Areal Bach and the "Edible Park” in Stephanshorn, have already been successfully implemented, demonstrating the feasibility and positive impact of the proposed strategies. The city administration and political stakeholders have endorsed the blueprint, establishing Grünes Gallustal as an influential, though informal, green master plan. Inspired by innovative urban planning models from cities such as Medellín, Vienna, and London, this blueprint promotes an integrated approach that blends urban planning, landscape architecture, and architecture. Its emphasis on low-barrier citizen participation highlights a commitment to fostering broad public acceptance and engagement. As Switzerland's first published comprehensive green urban planning concept, Grünes Gallustal offers a scalable, adaptable framework that can address urban challenges across Switzerland and beyond.
