A Café Scientifique is a forum, where for the price of a cup of coffee or a glass of wine, anyone can participate in the discussion of current scientific issues in the relaxing, informal setup of a Café!
How does it work?
What subjects will be discussed ? Any scientific subject that is of interest to the general public.
Who are the invited speakers? The speakers are researchers from the University of Zurich and ETH Zürich.

Blue-Green Infrastructure (BGI), such as trees, green roofs, bioretention basins, or constructed wetlands, has been researched for decades, yet the holistic and multifunctional implementation of BGI in the built environment remains elusive. BGI are often implemented for a single purpose, such as stormwater management or biodiversity conservation, with the remaining ecosystem services (or objectives) assumed to passively occur. In turn, synergies within BGI elements and implementation efforts are overlooked. From the literature, we compiled a suite of “objectives” that can be intentionally and holistically considered in the planning and design process, as well as, a list of 15 overarching types of BGI elements that should be considered across these objectives. Using a systematic literature review for each BGI element and objective, we found glaring gaps. Research related to BGI elements is consistently siloed among objectives and vice versa. To address this, continued coordination and holistic thinking is needed; however, we caution that evaluating too many options before implementation may impede decision-making and lead to a paradox of choice. In her talk, Dr. Cook will discuss solutions and challenges on how to move forward to implement multifunctional BGI in cities.
