This section explains what coloniality is, and how it is relevant to researchers. It gives examples of colonial histories of academia and how they continue to be relevant today, and invites researchers to reflect on the coloniality of their own disciplines and research practice. As Grantham scholars, all of our work revolves around the concept of 'sustainability', as such, we also reflect on the coloniality of sustainability and how colonialism is linked to the present climate crisis.
