This article examines the livelihood trajectories of Haitian migrants working in agriculture in Guadeloupe, considering the mechanisms contributing to their resilience/vulnerability. It proposes a conceptual framework that combines the sustainable livelihoods approach and the notion of “circulatory-transformative capacities” inspired by Sen. Through the analysis of capital and resources, individual choices and socio-economic trajectories, this framework allows us to understand the room for maneuver of migrants to achieve their life goals. The qualitative survey reveals how migrants mobilize, accumulate and circulate capital to support their strategies. It also highlights the influence of key resources on their trajectories and their vulnerability/resilience. Finally, it shows the importance of social capital and public policies to secure migrants' incomes, thus offering avenues for public action.
