In the absence of a coherent and convincing narrative of hope, new protagonists and their solidly responsible forms of imagining and struggling for livable futures enter the stages of parliaments, social media platforms and public spaces in cities around the world. It is precisely such spirit of collective solidarity, facing multiple crises at once, that links indigenous struggles over land and environment with the young people of the climate strike movement, as Brum has it, the “first generation without hope.” This leads to the overarching question of this theme issue: Who are the protagonists of Latin American futures? Who is imagining, writing, narrating such futures – how, when and where? In this CROLAR theme issue, we map protagonists of Latin American futures, both human and non-human, looking at the ways in which they act, create, and think futures.
