Urban ecologies are fraught with inequities, often resulting in humanitarian or charity solutions that emphasize lack rather than communities’ self-determination. While these inequities have been widely documented, the COVID-19 pandemic further reveals how these crises are not the sum result of individual failures. Rather, they are systemically produced through policies that harm people. How do Black urban residents contend with the sociohistorical antagonisms between feelings of scarcity (e.g., food and housing insecurity, underemployment, and financial strain) and aspirations for abundance? Using ethnographic encounters in Chicago and Austin we consider how practices of mutual aid are meaningful both spatially and affectively. First, we explore how mutual aid transforms “decaying” urban spaces to meet residents’ needs. Second, we explore felt experiences of mutuality in social relationships as distinct from authoritarian, charity-based relationality. Thinking these spatial and affective dimensions collectively, we work toward a framework of Black ecologies of care and mutual aid.
