Blue-green infrastructures are being built to protect cities from flash floods. But how do they affect biodiversity, water quality and the people living in the cities?
Provide knowledge how these blue-green infrastructures affect biodiversity, water and soil quality, hydrology, and many other aspects of the ecosystem in an around these structures.
Heavy rain events frequently cause flash floods in urban areas. Blue-green infrastructures are being built to infiltrate more water into the ground, such that the ground can act as a "sponge" and keep the water before it causes damage. Such blue-green infrastructures were also built on NMBUs campus in Ås, and we have assembled an interdisciplinary group of scientists to study how these nature-based solutions affect biodiversity, water and soil quality, hydrology, and many other aspects of the ecosystem. Not at least, we want to study how they are perceived by the people. This project is a work package of the project SPARE (Space for resilience - how do we plan for stormwater, biodiversity and recreation to increase urban resilience?), funded by the Research Council of Norway and lead by the Norwegian Institute for Water Research (NIVA)
Practical knowledge on construction of blue green infrastructures, ecology and determination of aquatic insects
contamination of blue-green infrastructures
drainage and functioning of blue-green infrastructures
Landscape architecture / urban design: Concept and design of blue-green infrstructures (BGI); integration of BGI projects in urban context. Recovering/resurfacing streams/creeks and their integration with respect to competing landuse.
Ecological entomology, forest ecology; especially how insects influence decomposition, and interactions between insects and other species groups
Aquatic botany, aquatic ecology; determination of aquatic plants and algae; what type of aquatic biodiversity develops in and around the blue-green infrastructures (BGIs)? Nuisance growth of algae and potential reasons for these? Changes in water quality along the course of the BGIs.
Plant ecology, population and community dynamics, biotic interactions within and between trophic levels
Water quality, coupling terrestrial and aquatic processes, mobility and retention of humic substances and heavy metals along a water course during different flow regimes
Susanne Schneider leads the work package on campus Ås. The project SPARE is lead by Isabel Seifert (NIVA).
