While determinants such as race, ethnic background and migration status are increasingly considered to be key factors in vulnerability to climate health risk, explicit consideration of immigrants’ climate health vulnerability in the European context is largely missing. In her contribution here, Panagiota Kotsila addresses this knowledge gap in the literature on climate change and migration studies by proposing a critical reconceptualization and planning for healthy and just cities. Building on critical studies of climate change adaptation and mobilizing postcolonial climate urbanism as an analytical lens, Kotsila argues for the importance of situated knowledges, feminist methodologies and migrant-centric epistemologies.
