In the drylands and mountains where pastoralists live, uncertainty is everywhere. In these settings, negotiating access to resources, navigating volatile markets, making use of varying social relations in times of stress, and responding to conflict and complex political dynamics is essential if livelihoods are to be generated. Pastoralism - the extensive, often mobile use of rangelands - is a vitally important livelihood practice globally. Rangelands cover more than half the world's land surface, supporting many millions of people and livestock, often in harsh and hostile environments. The book's chapters - with case studies from Africa, Asia, and Europe - explore how pastoral mobility is sustained, how resources are managed, how markets are combined, how social protections are provided, and how patterns of accumulation and investment are sustained in a more globalized, interconnected world. Focusing on the attributes of flexibility, adaptation, innovation, and learning for generating reliability, the book offers wider lessons for development in pastoral areas the world over that go beyond the rigid modes of planning, management, and control.
