Demonstrate the applicability of Nature4Cities Urban Challenges and indicators to real case studies
Mis à jour : 26 févr. 2020
Nature4Cities team compiled a database to demonstrate the applicability of the Urban Challenges (UC) and the indicator pool defined earlier in the project to real European case studies.
The aim is to propose tools able to evaluate complex urban challenges and integrated projects of implementing nature-based solutions (NBS) in the Nature4Cities platform.
Define Experts Models and Methods (EMM)
First, yet existing indicators capable to measure the impact of NBS on an UC were identified.
Then the most promising ones were selected, by a specific method, as Key Performance Indicators (KPI).
Based on these KPIs, we defined a range of Expert Models and Methods (EMM). They needed to be user friendly and able to use the KPIs. Models such as GreenPass®, i-Tree, TEB-Hydro or GIS related models were suitable.
The NBS archetypes identified in our typology were analysed regarding their conditions of measurability by a chosen EMM.
To reach this goal the following methodology was used:
1. Streamlining of NBS archetypes
Aim: determine how many groups or types of NBS can be designated in each Urban Challenge.
2. Building Scenarii
Aim: In addition to the parametrization of the utilized KPI, understanding the kind of information or data needed to apply the KPI, as well as what circumstances can influence the results.
3. select real case studies across Europe
Aim: collect examples on the applicability of EMM. It is important to understand both the benefits and the limiting factors of an EMM.
4. A database was compiled from the collected information
A work feeding the Simplified Urban Assessment Tool of the platform
The possible impacts of NBS implementation were studied in relation to 12 urban subchallenges, allowing to focus only at some dimensions of a given UC.
The database and the results of this work will be integrated in the data feeding the Simplified Urban Assessment Tool (SUA Tool), that will help users identify the best possible NBS, according to their requirements and predefined conditions.
Measuring the impacts of NBS in an urban environment is quite complex. Investigation is necessary prior to NBS implementation, in order to discern the most applicable solution. This database provides a general knowledge base of these applicable solutions during the NBS planning phase.
The case studies used to assess the indicators can serve as a guideline for urban planners, municipalities or other related experts on the utilization and benefits of these methods.
