Values about nature are formed at a young age via knowledge and direct experimentation with nature. Early education systems based on standard schools offer formal knowledge about nature but often only a limited connection to it. Therefore, many school systems in Europe have begun to turn schoolyards into natural gardening areas to provide a direct connection with nature (plants, insects, etc.). Vitoria-Gasteiz is the administrative capital of the Basque Country and is the 2012 European Green Capital. The city council is spearheading the transformation of schoolyards in the Basque Country. To strengthen the connection of pupils to urban biodiversity, CEA will codevelop novel, participatory approaches.
