In drylands, scientific research shows that mobile livestock systems derive the maximum social, environmental and economic benefits from these areas. These systems ensure both short-term security in case of shocks and, in the right conditions, investment capacity. However, it is difficult to develop indicators to understand and assess their contribution to territorial development, as they sit at the intersection between several scales of space and time, as well as of social and institutional organisation. The operational framework proposed here is aimed at rethinking the role livestock systems play in the sustainability of resources and societies in drylands. Six types of development indicators compare these three dimensions: characteristics of herds and of goods and services provided by the species bred, herd size, herd management system, management of land and resource use, access to state support, and dependence on markets. This framework invites policymakers to integrate these different scales in order to understand the adaptation mechanisms and the risks associated with intervention.
