Transdisciplinarity connotes a research strategy that crosses many disciplinary boundaries to create a holistic approach. It applies to research efforts focused on problems that cross the boundaries of two or more disciplines, such as research on effective information systems for biomedical research (see bioinformatics), and can refer to concepts or methods that were originally developed by one discipline, but are now used by several others, such as ethnography, a field research method originally developed in anthropology but now widely used by other disciplines. The Belmont Forum elaborated that a transdisciplinary approach is enabling inputs and scoping across scientific and non-scientific stakeholder communities and facilitating a systemic way of addressing a challenge. This includes initiatives that support the capacity building required for the successful transdisciplinary formulation and implementation of research actions.
Transdisciplinarity has two common meanings:
In German-speaking countries, Transdisziplinarität refers to the integration of diverse forms of research, and includes specific methods for relating knowledge in problem-solving. A 2003 conference held in Göttingen showcased the diverse meanings of multi-, inter- and transdisciplinarity and made suggestions for converging them without eliminating present usages.
When the very nature of a problem is under dispute, transdisciplinarity can help determine the most relevant problems and research questions involved. A first type of question concerns the cause of the present problems and their future development (system knowledge). Another concerns which values and norms can be used to form goals of the problem-solving process (target knowledge). A third relates to how a problematic situation can be transformed and improved (transformation knowledge). Transdisciplinarity requires adequate addressing of the complexity of problems and the diversity of perceptions of them, that abstract and case-specific knowledge are linked, and that practices promote the common good.
Transdisciplinarity arises when participating experts interact in an open discussion and dialogue, giving equal weight to each perspective and relating them to each other. This is difficult because of the overwhelming amount of information involved, and because of incommensurability of specialized languages in each field of expertise. To excel under these conditions, researchers need not only in-depth knowledge and know-how of the disciplines involved, but skills in moderation, mediation, association and transfer.
