How people relate to and see themselves as part of nature relations differs worldwide and often depends on culture and worldviews. Nonetheless, challenging the dominant Euro-Western epistemic domination is needed to attain more equitable and sustainable future visions. This change entails fostering decolonial mediation between different knowledge systems in a context of intersectional difference. The collective struggles of Black, Indigenous, and other Women of Color (BIWOC) for self-determination shed light on pathways of decolonial mediations and how to attain epistemic equity when thinking about the future. Echoing the call of BIWOC to use decoloniality in knowledge co-creation, we co-created a border space together with 20 BIWOC in the Putumayo department of Colombia. In this space, we jointly envisioned three radical visions of the Amazon through scenario-building exercises between 2022 and 2023. Storytelling is a powerful tool to capture the BIWOC’s differentiated experience of the world and to explore their individual and collective emancipation from different forms of oppression. Decolonial mediations support the (co-)design of a “safe enough” space for questioning and rethinking Euro-Western domination. Our research also indicates that incorporating decolonial praxis into sustainability transformation research can allow for a more radical envisioning of the future.
