The complexity and urgency of global change challenges requires the collaborative understanding and action of a range of knowledge systems and actors.  Transdisciplinary approaches thread together expertise from across the sciences and unite them with a user community that brings its own knowledge and experiences to co-frame problems and co-create actionable knowledge in response to issues of joint interest.  It provides an even playing field for all scientific endeavors – fundamental, applied, regulatory – and all knowledge systems – academic and non-academic.  This session will highlight the growth and legitimization of transdisciplinary approaches, presenting specific examples of collaborative projects that transformed not only our understanding, but fostered policy and practice changes to address critical global change needs.

This session, which will take place during the 2019 American Geophysical Union Fall meeting (9-13 December 2019) is convened by Erica Key (Belmont Forum), Heide Hackmann (International Science Council), Tobias Buser (Network for Transdisciplinary Research, td-net), and Hilary Bradbury, SDG Transformations Forum Learning Futures Working Group, AR+.

Abstracts for this session are now being accepted.
