Latin America is the most urbanized and unequal region in the world. It is also the second most disaster-prone region globally. Its vulnerability to floods, landslides, droughts, storms, sea level rise, and infectious diseases is rapidly increasing due to the climate crisis. “Social Learning for Urban Climate Justice in Latin America” (LEARN-UCJ 101150094) project aimed to unpack the potential of social learning for Urban Climate Justice in two representative Latin American cities, Bogota (Colombia) and Mexico City. (Mexico). The project was implemented between 01 September 2024 and 30 April 2025. To achieve its general objective, the project aimed—through a decolonial perspective—to identify Urban Climate Justice (UCJ) claims and collective actions, explore collaborations between political institutions and stakeholders, analyse the integration of climate justice into urban planning, and assess the role of social learning in advancing UCJ.
