An interdisciplinary text on the world's savannas, covering the geography, ecology, economics and politics of savanna regions. Savannas are a distinct vegetation type, covering a third of the world's land surface area and supporting a fifth of the world's population. There has been a wide range of literature on the subject, but the majority of work has focused on the ecology or development of savanna areas, ignoring the wider interdisciplinary issues affecting contemporary savannas.
