The open public space within one neighborhood represents a critical space for socialization. However, local governance participatory mechanisms need to be more sophisticated and developed in the context of a post-socialist society in transition, such as Serbia or other Eastern European countries, to achieve this quality. In such systems, children and youth usually do not participate in decision-making processes regarding the enhancement of these spaces, so their needs are neither included nor considered. The usual practice is that the open public space maintenance or renewal projects are top-down decided, and with limited funds, so often design solutions are replicated, not fitting the contemporary real needs of the end users, without relation to the climate change policies and measures. Therefore, this method focuses on including marginalized groups and promoting the Nature-Based Solutions co-creation on a community level.
