Migration in Latin America and Caribbean is no longer a one-way phenomenon toward the United States, but has become a global, complex, and multiscale experience linked to contemporary crises that reinforce each other: inequalities, climate change, conflicts, pandemics, and technological transformations. This book explores the causes, implications, and tensions of these mobilities, considering the structural, institutional, environmental, and cultural factors that shape them, as well as their gender, ethnic, and class dimensions. Migration is not only the displacement of people, but also of ideas, knowledge, and cultures, transforming both those who migrate and the societies that receive them. With a historical and relational perspective, this books offers the reader a comprehensive understanding of migration as a vital phenomenon in the construction of citizenship, social justice, and possible futures in Latin America and the Caribbean.
