Nowadays, where transdisciplinary research approaches have become a demand in most of the call for proposals for research programmes, the different concepts and disciplinary diverse understandings of inter-, multi-, and transdisciplinarity motivate discussions in science and in practice.

Those research approaches are often coupled with the claim of transition research or a transformational science.

Both, international and national, many projects often initiated by science and practice ask the question in how far a broad definition of the term as well as to what extent it is necessary.

Especially in the field of health-promoting urban development the question will be in how farcooperation of sectors and disciplines may benefit of the concepts and findings of the transdisciplinarity-research.
