Sustainability performance of blue-green infrastructure across seasons and with various designs
The Sustainable Development Goals (SDGs) affect societal development within multiple sectors, both strategically and at street level. For instance, SDG 6 and SDG 11 have contributed to a shift in urban stormwater management that has traditionally been pipe-based, including only control of runoff volumes, to a more multi-functional nature-based blue-green infrastructure (BGI), where"blue" areas are characterized by (temporarily or permanent) open water and "green" areas by vegetative systems. As an alternative drainage approach, the use of BGI was developed and primarily evaluated in regions with temperate climates where a recent focus has been the role of BGI as providers of multiple ecosystem services within an urban context. However, as the use of BGI expands into non-temperate zones, there is a clear need to address the fact that these nature-based systems are not only blue and green. For example, in northern climates BGI systems e.g., street-scale bioretention systems include white aspects (i.e. snow) for varying time periods. Whilst the design options for bioretention are varied and complex, (e.g., differing combinations of construction styles, filter materials and plants) research into the impact of alternative design options has focused on technical evaluations, i.e., the impact on pollution treatment and/or hydraulic control of stormwater. Knowledge of how these different bioretention designs affect other sustainability criteria, such as economic, social, and environmental aspects, needs to be fully developed. The purpose of this licentiate thesis was to characterise and compare different street-scale bioretention designs to gain a better understanding of the relative sustainability of different bioretention systems and how the use of BGI can contribute to SDG delivery. In addition, the aim was to lay the theoretical foundation for an extended BGI concept by including white urban environments within the concept of blue-green-white infrastructure (BGWI). The overall goal was to contribute with new, ...
