South Africa’s escalating environmental challenges, exacerbated by the Anthropocene, demand a radical rethinking of design education. While science and engineering have developed mechanisms to address ecological degradation, design education remains rooted in Human-Centred Design, which prioritises human needs while neglecting planetary systems. This paper argues for a paradigm shift toward Planet-Centred Design, supported by interdisciplinary collaboration through STEAM(D) (Science, Technology, Engineering, Arts, Mathematics + Design) and biodesign as transformative approaches for South African tertiary arts, design, and engineering education.
