In the book Migrations, Sebastiao Salgado turns his attention to the staggering phenomenon of mass migration. Photographs taken over seven years across more than 35 countries document the epic displacement of the world’s people at the close of the twentieth century. Wars, natural disasters, environmental degradation, explosive population growth and the widening gap between rich and poor have resulted in over one hundred million international migrants, a number that has doubled in a decade. This demographic change, unparalleled in human history, presents profound challenges to the notions of nation, community, and citizenship. The first extensive pictorial survey of the current global flux of humanity, Migrations follows Latin Americans entering the United States, Jews leaving the former Soviet Union, Africans traveling into Europe, Kosovars fleeing into Albania and many others. The images address suffering while revealing the dignity and courage of the subjects. With his unique vision and empathy, Salgado gives us a picture of the enormous social and political transformations now occurring in a world divided between excess and need.
