Decolonial perspectives open up epistemic and practical insights for science communication. Following critiques of a deficit-model framing of the field, science communication has been redefined as an inclusive cultural space of meaning-making around science. From a decolonial lens, however, a cultural perspective necessitates a fundamental reckoning with the historical and contemporary politics of knowledge claims, including the erasure and devaluation of entire knowledge-systems in the process of Westernization. In recognizing and learning from these histories, science communication can learn from parallel developments within the sciences. It can also learn from contributions made by decolonial scholars to the global challenge of navigating sustainable futures. This piece briefly discusses one such example, drawing from scholarship on the ontological cosmovision of Ubuntu and its relevance to climate change dilemmas today.

In this commentary we are concerned with what mainstream science communication has neglected through cultural narrowness and ambient racism: other practitioners, missing audiences, unvalued knowledge, unrecognised practices. We explore examples from First Nations Peoples in the lands now known as Australia, from Griots in West Africa and from People's Science Movements in India to help us reimagine science communication. To develop meaningfully inclusive approaches to science communication, we argue there is an urgent need for the ‘mainstream’ to recognise, value and learn from science communication practices that are all too often seen as at ‘the margins’ of this field.
