2.00 | Story Corner 2 Mapping and evaluation of urban green infrastructure

Valuing urban green infrastructure – green infrastructure assets and audits, quality control, assessment, evaluation and project certification.

  • Irena Niedźwiecka-Filipiak Head of the Institute of Landscape Architecture, Wrocław University of Environmental & Life Sciences | The green infrastructure network project in Wrocław Functional Area – first steps to implementation

Wroclaw’s green infrastructure strategy covers the 29 municipalities of Wrocław Functional Area (WFA) and beyond. By 2014, we defined the strategy’s main elements and by 2016 implemented its details.

First, we created the backbone of the strategy, identifying existing connections between units, and places where connections were missing. Then we hierarchized the types which depend on system nodes like crossroads, and the environmental protection needed. Finally, we classified their functionality and potential threats from future development.

Then we defined the functions that elements like rings or wedges perform and sought ways to implement them at a local level. Working with communities and local government, we explained green infrastructure and its benefits, surveying residents’ needs and preferences to find the best solutions.

  • Prof Rosi Stangl BOKU University of Life Sciences Vienna | Urbane GmbA – Urban green space potential in the Viennese building stock – a pilot assessment study

Urbane GmbA aims to explore and assess the potential of greenable (vertical and horizontal) area from building and obscured stock. Large scale advancement of urban green infrastructures requires reliable data referring to current state and potentials. Currently available instruments are fragmented and only give incomplete pictures.

Urbane GmbA explores on how to merge established approaches. The application results will be evaluated and verified at two pilot areas where large-scale greening is intended to be implemented. Urbane GmbA will define and categorise suitable measures and State of the Art technologies to expand green infrastructure and to test the technology readiness level.

  • Joost de Gier Sempergreen Netherlands | Green roofs and biodiversity – the results of scientific research

Green roofs offer a huge potential habitat for plants and animals in urban areas. In collaboration with Dutch Butterfly Conservation, Sempergreen has conducted research into the functional contribution of green roofs to the stimulation of biodiversity in urban areas.

The focus of this research was whether or not bees, butterflies and hoverflies have a preference for a specific vegetation blanket and whether butterflies can reproduce on a roof. Only by establishing such facts can we speak about a functional roof environment that is beneficial for biodiversity. The outcome of this research has resulted into setting new guidelines for green roofs to avoid them becoming an ecological trap.

  • Panos Fetsis LIFE Programme Communications Team | LIFE Urban-Adapt – testing climate adaptation measures for the City of Rotterdam

The project demonstrates an innovative, participatory approach to the large-scale implementation of urban adaptation strategies and related measures in order to bolster acceptance among the public and stakeholders. The project increases the water retention capacities within an urban area and restores ecosystems and develops green and blue infrastructure to increase the climate resilience of two districts of Rotterdam (ZoHo and Nieuwe Maas).
