Green Infrastructure and Integrated Optimisation Approach Towards Urban Sustainability: Case Study in Altstetten-Albisrieden, Zurich

In light of the challenges faced by urban areas due to increasing populations and spatial limitations, urban green infrastructure is essential for fostering environmental equilibrium, enhancing community well-being, and promoting sustainable urban development. This situation emphasises the imperative for strategies that harmonise the growing need for constructed environments with the improvement of the natural ecosystem in urban locales. This study centres on diverse perspectives of urban green infrastructure and seeks to develop an integrated methodology to optimise the allocation of green space, utilising Altstetten-Albisrieden in Zurich as a case study. It investigates the distribution and accessibility of urban green space within the district from multiple perspectives and visualises the findings using a 10-meter rectangular grid. By employing clustering algorithms, the study categorises the grid cells according to their resemblances. Radar charts depict the attributes of each cluster and suggest opportunities for fortifying urban green infrastructure. Ultimately, the study provides a thorough analysis of urban green space provision in Altstetten-Albisrieden, presenting extensive recommendations for optimising green space planning with respect to social equity and natural recolonisation at the district level.
