2020-Jun-30 : First virtual meeting of Europe-wide COST Action Circular Cities
On Monday 29th June, COST Action “Circular Cities” held its first virtual workshop with 60 people from 29 countries participating. The day-long meeting was dedicated to starting the joint development of a Catalogue of Technologies for providing/recovering resources through nature-based solutions (NBS). Aim of the catalogue is to support efforts by municipalities and initiatives to achieve circularity in cities by employing nature-based solutions. Circularity, according to our definition, means less resources used and less waste.

Katrin is the UK representative at this Cost Action – fully titled: COST Action 17133 Implementing nature-based solutions for creating a resourceful city – which started in October 2018 and will run for a further two years.
Four aspects of the urban metabolism will be linked in COST "Circular Cities": water, food, resource recovery and the built environment. (image: COST Action "Circular Cities" 2019)
In preparation of the workshop, colleagues from the University of Ljubljana (Slovenia) and the research institute ICRA (Spain) had prepared a selection of potentially suitable NBS by screening 250 NBS from four Horizon2020 projects – UrbanGreenUp, UnaLab, Nature4Cities and ThinkNature – as to their contribution to ressource circularity.

In breakout sessions, organised by one of the Action’s co-leads, BOKU Vienna, the participants had a first go at evaluating the selected 32 NBS as well as about 40 further NBS that had been identified before through a survey amongst all COST Action partners (more than 200). Evaluated examples ranged from water-focused NBS, such as raingarden and constructed wetlands, to energy-focused NBS, such as bio-solar green roof, to waste-focused NBS, such as anaerobic treatment plants, to food-focused NBS, such as food forests, market gardens and hydroponics.
