The last two reports out focusing on monitoring and maintenance and scaling the NBS model
05 November 2026
Maintenance guidance for nature-based solutions brings together the work done in City Blues from the questionnaires and interviews with the partner cities, through the monitoring campaigns in Aarhus, Malmö, Tampere and Berlin, to the development of the BGI (blue and green infrastructure) Inspector. Based on this, the report provides guidance on monitoring and maintaining NBS, linked to the City Blues NBS model.
Analysis on collaborative mission potential of the NBS model focuses on how far the NBS model can be used jointly and scaled up. The NBS model is a web-based tool that guides cities through nature-based stormwater management, from financing and planning to maintenance and monitoring, using a catchment-based approach. The analysis draws on two workshops and bilateral discussions with partner cities.
Happy reading!
