AScUS (un)Conference 2021

The 2nd Actionable Science for Urban Sustainability (AScUS) unconference continued the success of the previous edition in producing actionable and multidisciplinary knowledge to tackle urban sustainability challenges across the globe. Different participant-driven, interactive and interdisciplinary discussion sessions were held over the four days of (virtual) conference, tackling topics from urban mobility, local reuse activity, urban transformation until risk assessment, teaching and science fiction story writing. We had inspiring discussions, fruitful brainstorming sessions, and also a lot of fun.

Remember that AScUS did not feature any individual presentations; instead, all contributions from participants were submitted online ahead of time. These remain accessible for the participants via the AScUS platform and allow browsing through and eventually reviewing the contributions.


The goal of AScUS 2021 was to produce actionable insights. This included the development of "Path-to-Action" documents that were based on the discussion sessions.
