Transdisciplinarity and Action Research Introduction to the Special Issue

Since 2001, the international „Global Change Research Community“ has propagated sustainability science as an interand transdisciplinary approach to the assignment of tasks related to sustainable development (Kates et al., 2001). It has afforded a new perspective on man-environment research and demands the inclusion of various branches of psychology, including environmental, health, community and architectural psychology besides many other applied research disciplines. It furthermore attempts to combine psychological knowledge with other knowledge fields (e.g. natural sciences, humanities, engineering and design research). In addition to the exchange between the disciplines, the cooperation with practitioners is essential to attain real-world social changes towards sustainable development.
