2nd Actionable Science for Urban Sustainability Unconference (AScUS 2021) - Call for Contributions

Sustainable Urban Systems

2nd Actionable Science for Urban Sustainability (AScUS 2021)
An Unconference on Urban Sustainability to Generate Actionable Solutions
June 1-4, online

The 2nd Actionable Science for Urban Sustainability (AScUS) unconference continues the success of the previous edition in producing actionable and multidisciplinary knowledge to tackle urban sustainability challenges across the globe. It is conceived as a convergence platform for researchers and practitioners of all backgrounds, from political science and psychology to architecture and engineering, from basic research to policymakers, NGOs and entrepreneurs, focused on the development of actionable and scalable solutions and their transfer into action.

Unlike conventional conferences, AScUS 2021 is a participants-driven unconference with the mission to engage attendees with stimulating in-depth discussions and participatory sessions. The unconference is organized around a diverse selection of interdisciplinary discussion topics submitted by the participants, more similar to a workshop in format.

The unconference will spread over several weeks and culminate in a virtual event on June 1-4. Every registered participant is allowed to submit one contribution (e.g., recorded presentation) before the unconference (abstracts are optional but encouraged). All contributions will be uploaded by individual participants before the unconference and serve as a basis for discussion and knowledge exchange during the pre-unconference activities. The unconference will then culminate in a virtual event with interactive discussions oriented towards generating tangible outcomes in the form of a path-to-action contribution.

Interested participants are invited to submit:

  • Abstracts (300 words). Abstracts can have any format (e.g., text, audio, video,.. ). Information on how to submit your abstract will be posted in early February. Abstracts are optional but encouraged for fostering exchange during the open feedback period. Whether an abstract has been submitted or not, every registered participant will be allowed to submit one contribution (e.g., recorded presentation or poster) before the unconference. Acceptance letters are available upon request.
  • Discussion topic proposals (200–500 words). Everyone can submit a discussion topic proposal even if they have not submitted an abstract. Proposals should include a brief synopsis of the discussion topic, a list of activities that are planned, and a general idea of the type of the path-to-action contribution that is expected (e.g., white paper, podcast, website, performance). We encourage participants to actively suggest discussion topics, being the interdisciplinary exchange of ideas and knowledge one of the key objectives of AScUS.

Note that we require all participants to register by April 15 since the event officially starts with pre-unconference activities.
