Nomadic herders in Mali's Sahel grasslands, the Fulani cowboys embark on an annual migration across the savanna. It's a cycle that connects the Fulani to their past but puts them increasingly under threat from Islamic militants, climate change, and the urbanization that lures away their young. A chronicler of endangered cultures, Anna Badkhen takes the journey with them, and here she provides a vivid travelogue that is also a reflection on the rich past, transitional present, and uncertain future of these wanderers and hustlers, griots and holy men.
