The contribution of Carl-Friedrich Graumann for the development of environmental psychology and for the study of people-environment relations will be discussed in relation to the social psychological roots of environmental psychology. A paradigmatic example of this roots, which is also representative of Graumann’s contribution to the development of people-environment studies, is offered by the role of peopleenvironment relations in the development and construction of the individual self, and by the place-identity concept. Another issue representative of the social psychological roots of environmental psychological research, which has been in the focus of Graumann’s studies, relates to the process of social construction of the environment, and to the study of environmental discourse. For both these issues, the findings of recent studies by the authors will be briefly presented and discussed.
