With detailed data from nine sites around the world, the authors examine how the so-called 'fragmentation' of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. 'Rangelands' make up a quarter of the world's landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.
