This research project, funded by the Dr. Gustav Bauckloh-Stiftung, Dortmund, is intended to provide a basis for the historical development of nature conservation, the legally defined goals and tasks of nature conservation (and landscape management), the realization that despite the introduction of a large number of instruments under nature conservation law and comparatively far-reaching efforts by official and voluntary nature conservation, it has not been possible to halt the decline in biological diversity, particularly in Germany, as well as first empirically secured knowledge about the experience and learning process of children and adolescents in dealing with nature, which not only proves positive effects for the cognitive development of children and adolescents, but also determines longer-term differences in behavior towards nature and the environment, an innovative concept will be developed using the example and with the support of the city of Dortmund, with which the framework and implementation conditions for nature conservation in the city can be sustainably improved. Project partners are the WWU Münster, Department of Educational Sciences, focus on school theory and research, and the Environmental Agency of the City of Dortmund.
