Green Urban Infrastructure
Biodiversity is at the heart of Urban Green Infrastructure and contributes to ecological networks, to the regulation of water, climate, air quality and to human well-being.
Urban biodiversity is linked to the diversity of ecosystems: maintained green spaces, built green roofs and walls, spontaneous wastelands, aquatic environments.
Wasabi is a space to experiment the different types of urban environments, their capacity to host native biodiversity and provide ecosystem services.
In a directed wasteland, the fauna and flora spontaneously recolonise the environment. The design is inspired by nature. Adaptive management drives the ecosystem dynamics.
Green roofs and walls
Green roofs and walls are human-built ecosystems composed of support structures, techno-soils and selected vegetation. With controlled experiments on green roofs and walls, we test the effect of techno-soil properties and native plant diversity on water cycle and urban climate. TERRA green roofs allow real-world experimentation on a building scale. Vegetation developed is similar to natural ecosystems and is based on native flora to strengthen natural ecosystems and support for pollinators.
Native wetland biodiversity will be deployed in the rain garden to create wetland-like environments in the Gembloux ecological landscape and contribute to the ecological network.
Throughout the Wasabi site, a differentiated management plan for green spaces has been put in place. A management gradient, with a greater or lesser emphasis on spontaneous biodiversity, is applied depending on the areas and their use.
