Much has been said about the importance of pastoralist livelihoods for the effective and sustainable use of drylands around the world. Yet, pastoralist societies are experiencing more pressures to their way of life than ever before. These pressures and changing trends are jeopardising pastoralist livelihoods as well as the sustainability of dryland resources.
In the face of this challenging reality, this paper aims to analyse how land tenure regimes of pastoralist societies living in the Andean altiplano have transformed over the last 50 years. It also discusses the implications of these transformations for the sustainability of resource management in these areas, based on the premise that a better understanding of customary land tenure regimes can help to inform public policy and decision making.
