In a number of European countries a particular understanding of transdisciplinarity has evolved over the last decades, initiated by research on environmental problems. The focus of this type of transdisciplinary research is on helping society solve wicked problems. A specific feature is that, in addition to researchers of different disciplines, representatives of civil society and the private and public sectors are involved in the research process. “Addressing Wicked Problems through Transdisciplinary Research” describes this type of transdisciplinary research, its roots, and the challenges to be dealt with when addressing wicked societal problems.
