This paper asks how can we as geographers, occupying positions of relative privilege but also beholden to institutions entangled with legacies of colonialism and ongoing colonization, find and embody our responsibilities to Indigenous people and nations and contribute to decolonization within and beyond the academy? We begin by reflecting on Doreen Massey's (2004) theorization of geographies of responsibility and critiques of it in the intervening years. We then engage with important considerations including the politics of recognition, relational grammars of settler colonialism and Indigenous notions of relationality. To avoid the traps of recognition politics, which often foreclose the more transformative possibilities of responsibility, we propose ways of taking of decolonial responsibility in our teaching, research and professional service. While we cannot provide simple solutions to the difficult challenge of pursuing decolonization in the academy, we believe that centralizing and prioritizing relationships of responsibility to and through place in support of resurgent Indigenous nationhood is required to avoid the denuding, individualizing process of colonial recognition and superficial performative decolonisation.
