Transforming spaces with artistic installations: children as co-producers of sustainable cities

The violation of children's right to free exploration of the open spaces that shape their residential surroundings is a barrier to achieving the Sustainable Development Goals in Brazil and worldwide. Poor quality open spaces have contributed to the decline in children's independent mobility. This research explores the potential of tactical urbanism practices with children in the creation of open spaces supportive of their independent mobility. To achieve this, various methods were employed for data collection, including participant observations, field notes, systematic observation sessions, videos, and semi-structured interviews. The analysis was conducted using multicriteria analysis and thematic analysis techniques. The study found that tactical urbanism with children is a powerful tool for making urban open spaces safer and more appealing for children free exploration and enjoyment.
