BiodiverCities project initiated the cooperation of the school and municipality. Together, teachers, the expert and municipality representative co-designed and co-developed the programme and workshop activities. Groups of students participating in Digital Biocitizen workshop independently co-created digital solutions for learning about nature and mapping nature in the city. This was also their first time to deal with the topic in the school as well as the mode of co-creative work in groups. Moreover, this activity as part of BiodiverCities project will inform the policies on biodiversity and citizen engagement and deliberative democracy. Next, we will share this experience with other EU cities that are partners in BiodiverCities project (Leiden, Palma, Valongo, Stavanger, Vilnius, Sofia, Novi Sad, Palermo and Regalbuto). With the project Digital BioCitizen we supported mainstreaming participatory practises in public institutions, greening cities with citizens and in our case sensitising students about biodiversity and active citizenship. With initialising this participatory process we stimulated institutional change. Exchangange of knowledge & co-creation of civil servants, practitioners, citizens and EU officials brings sustainable impact and changes in curriculum and changes in institutional practices. BiodiverCities Maribor increases the awareness of the underpinning role of urban biodiversity by setting up citizen engagement activities. The results of DigitalBioCitizen action will help to understand better how to involve citizens in making cities greener and more biodiverse.
