Strategic green infrastructure planning and urban forestry
No full textThe green infrastructure (GI) approach, which takes an integrative perspective on a city's or city region's green spaces, has rapidly become accepted as a policy and planning tool. This chapter looks into the history and concept of GI, tracing some of its origins in landscape and urban ecological thinking. The focus is on the relevance of the urban forest as a fundamental element of green infrastructure from the neighbourhood to city-regional level. To exemplify the synergy existing between urban forestry and GI, the following two case studies are presented: Regional urban forest parks in Milan and the Melbourne Urban Forest Strategy. Urban forestry and GI can be seen as two sides of the same coin; so while there are differences in emphasis and approach, commonalities easily exceed the differences. Each approach has much to gain from the other and many of the main advocates are the same. For this reason key international meetings give space and encouragement to GI contributions
Do urban green spaces cool cities differently across latitudes? Spatial variability and climatic drivers of vegetation-induced cooling
Full text linkUrbanization transformed global landscapes, intensifying Urban Heat Islands (UHI), further exacerbated by climate change. Sustainable green urban design offers cooling effects through evapotranspiration and shading with varying effectiveness across regions. This study investigates the role of urban vegetation, particularly trees and grassland, in moderating temperatures across nine European cities from 40°N to 53°N, with Temperate to Mediterranean climates. High-resolution Land Surface Temperature (LST) data, downscaled using a Gradient Tree Boosting model, were integrated with the De Martonne Aridity Index and a Contribution Index (CI) to quantify vegetation-driven cooling across a latitudinal gradient. The results show that tree and grassland cooling effects are not spatially uniform: vegetation in cooler, less arid cities provides stronger thermal mitigation. Regression analysis using Random Forest and Generalized Additive Models revealed that vapor pressure deficit (VPD) most strongly influences vegetation cooling, followed by precipitation and solar radiation. Even similar vegetation types demonstrate differing cooling performance depending on local climatic conditions. This study emphasizes the importance of optimizing urban greening strategies to geographic and climate-specific contexts, offering actionable insights for designing climate-responsive green infrastructure to reduce urban heat
Das Potential ökosystem-basierter Klimaanpassung: Integration in die Stadtplanung und Wirksamkeit zur Hitze- und Starkregenregulation
No full textEcosystem-based approaches have gained increasing attention for urban climate adaptation. This thesis assesses their current state of integration and their effectiveness for regulating extreme events. In municipal adaptation strategies of German cities references to the components of ecosystem-based approaches could be identified. Scenario modelling further revealed the contribution of different types of green infrastructure to heat and runoff mitigation, but showed varying potentials. Finally, practical implications for urban planning were discussed.Ökosystem-basierte Ansätze für städtische Klimaanpassung erfahren derzeit viel Aufmerksamkeit. Diese Dissertation untersucht ihre aktuelle Anwendung und ihre Wirksamkeit zur Regulation von Hitze- und Starkregenereignissen. In Klimaanpassungsstrategien deutscher Städte wurden Referenzen zu diesen Ansätzen identifiziert. Durch Szenariomodellierung wurde weiterhin der Beitrag verschiedener Begrünungsarten zu Hitze- und Starkregenregulation quantifiziert, welcher unterschiedliche Potentiale bietet. Abschließend wurden Handlungsempfehlungen für die Planungspraxis diskutiert
