This chapter examines how specific phenomena—mining disasters—and the construction of place(s) related to them produces testimonial injustice. Focusing on the collapse of the Vale Company tailing dam in Brumadinho, Brazil in January 2019, we explore the way in which ‘global’ and ‘local’ interact in two forms of place in which time is a key component: ‘corporate place’ and ‘grassroots place’. We argue first, that corporate place can be seen to be used strategically to produce epistemic injustice; second, that this can be further seen as epistemicide; and, third, that place—and specifically grassroots place—is also part of strategies to create epistemic justice and limit epistemicide. In this analysis we draw on empirical work undertaken with the Naô Xohã indigenous village, a group significantly impacted by the Vale tailing dam collapse to show how their experiences, ways of knowing and life have been excluded (and harmed) in responses to, and life after, the dam collapse. We also reflect on the role of researchers in producing knowledge through empirical research on the disaster. As knowledge producers, universities can reproduce epistemic injustices or serve to constitute critical spaces and expand the silenced voices in these processes.
