The overall objective of SUST 501 is to delve into the ways in which people collaborate to address sustainability challenges. SUST 501 delves into what sustainability science and action entails from academic and practitioner perspectives. We begin by establishing the cross-cutting concepts that run throughout sustainability science including different ways of knowing, ethics, collaboration, and interdisciplinarity. The second part of the course builds on this foundational knowledge to explore more deeply the collaborative nature of transdisciplinary efforts, look at how boundary work can bridge gaps between different ways of knowing, explore how to co-produce knowledge, and analyze how to jointly develop sustainability solutions.
