COST Circular City (2018-)
Katrin and André represent Great Britain in Europe's longest-standing research network COST Action. The project is fully titled The Circular City: Implementing nature-based solutions for creating a resourceful city and will run over 4 years.

Main aim and objective of the Action is to build an interdisciplinary platform for connecting city planners, architects, system designers, economists, engineers and researchers from social and natural sciences to develop nature-based solutions in the urban landscape that facilitate circular economies based on the 3Rs (Reduce, Reuse and Recover).

Nature-based solutions (NBS), especially Green Infrastructure, are currently introduced into urban landscapes worldwide to better cope with challenges cities are facing. These challenges are, f.e., urban heat islands, flooding, treatment of waste- and runoff waters from different origins and food provision. Whilst NBS offer a range of ecosystem services beneficial for the environment, they are often built without considering the system’s perspective. They thus can only fulfil a single function with little consideration for their recovery potential, f.e., of waste and water or their positive symbiosis with other systems.
Three aspects of the urban metabolism - water, food, resource recovery - will be linked to the built environment. (image: COST Action Circular City)
The main outcome of the project will therefore be a guideline on combined nature-based solutions and circular economy possibilities within the urban environment to enable cities to better cope with future challenges.

In order to achieve this, the participants from all EU countries plus some international guests meet regularly - since the outbreak of Covid-19 online - for workshops and discussions and publish and disseminate their findings in academic as well as social media.
