In this dissertation, I look at Nature as another dimension on which coloniality affects. To this end, I propose two theoretical movements. The first is to deepen the notion of coloniality of Nature, understanding that even in a critical movement such as decolonial thinking, Nature is placed on the margins, making it necessary, therefore, to reposition it and understand how coloniality affects it. The second is to present the Environmental Contract, inspired mainly by Charles Mills s Racial Contract, as a subversive contract that highlights how the subjugation of Nature is relevant to the colonial social, political and epistemological domain. Both movements are related to the discipline of International Relations, positioning this text as a proposal for thinking about the international. For this analysis, the methodologies chosen are intersectionality, precisely because it allows the analysis of the incidence of hierarchies in more than one dimension of human and non-human lives, and cartography, which allows research to be affected by the field and the path also be traced while walking. Finally, I start from the knowledge cultivated about the climate crisis with the intention of proposing a break with the hegemony of the social, political and productive organization centered on the state, capitalism and coloniality-modernity, without, however, believing in a return to the past and without romanticizing non-modern forms of organization, having the peasant movement of struggle for land, especially the Landless Workers Movement (MST), and its international counterpart, La Via Campesina, as decolonial and intersectional practices of social, political and epistemological transformation, as well as transformation of the relations between humans and Nature and between human groups.
