In her lecture at the University of Barcelona titled “Just Transition in the Polycrisis: Latin American Alternatives to Green Colonialism,” Sabrina Fernandes talks about eco-social transitions, underscoring the pressing need to address climate change’s impacts, highlighting Brazil’s severe flooding crisis, and challenging mainstream green transition narratives that often ignore the persistent inequalities and dispossessions in the Global South. Sabrina advocates for a nuanced approach to solutions, stressing that they should not worsen issues in other regions, and calling to action emphasizes the importance of internationalist and interconnected strategies to effectively address both ecological and social crises.
