I would like to ask if some of you know or have applied a participatory planning system with a playful and innovative approach in cities with an intermediate size, approximately 150,000 inhabitants. I appreciate your references in advance?.
I have an example which is not exactly what you are looking for (more public dialogue) but it is a start:
the German governance developed a climate action plan 2050 with a huge participatory effort, including federal government and ca. 500 citizens in whole Germany
It's really valuable information, I'm going to ask for help from a German translator. I am very grateful for your suggestion. Best regards from Ecuador.
