In recent decades, Cuba has experienced intensifying climate and environmental change alongside a deepening socio-economic crisis, which has contributed to new waves of emigration that reinforce already dense transnational connections and networks. While early research on environmental change and mobility often framed migration as a last-resort response and immobility as the result of being unable to leave, more recent scholarship has shown that moving and staying form a broader spectrum of coping and adaptation. Building on relational and translocal approaches to mobility, this article understands coping and adaptation as processes negotiated across households, places, and networks, where mobility and immobility are mutually constituted. The article examines mobility-linked coping and adaptation strategies from the perspective of origin households with transnational connections living in a highly exposed peri-urban coastal village in Havana Province, Cuba. Based on 2 months of qualitative fieldwork with 21 selected households, it develops a typology of coping and adaptation practices and analyzes how these practices unfold through translocal networks. Findings indicate that among sampled households, mobility and transnational connections function as key adaptive resources: remittances support incremental housing reinforcement, self-directed climate-related residential mobility, and emergency responses, while translocal networks circulate information, advice, and affective support. Households who remain in place are active co-producers of resilience. However, mobility cannot substitute for robust in situ adaptation. Access to mobility-driven adaptation resources is uneven, and their effectiveness is constrained by sanctions, inflation, restrictive monetary policies, and the informalization of transfer channels.
