Abstract Context The global drylands cover 41% of the terrestrial surface and support millions of pastoralists and host diverse flora and fauna. Ongoing socioeconomic and environmental transformations in drylands make it imperative to understand how to achieve the twin goals of food security and ecosystem health. Objectives The review focuses on examining the patterns of rangeland vegetation dynamics and livelihood transformations associated with changes in pastoralist mobility. Methods We conducted a comprehensive review of literature on dryland sustainability based on the coupled systems framework and through the lens of mobility, which reflects not only human and livestock

movements but also the unique lifestyles and cultural identities of people in drylands. Results We find that mobility, which is critical for pastoralists to survive and thrive in the drylands, is generally in decline and has significant implications on dryland sustainability. Reduced mobility exacerbates bush encroachment and land degradation, as sedentarized pastoralists use the rangelands more recursively. Associated with declining mobility is livelihood intensification and diversification, but such livelihood transitions may carry both socioeconomic and environmental risks. Conclusions We argue that to advance landscape sustainability science and reconcile concerns over environmental conservation and human well-being across the global drylands, we must better understand the underlying mechanisms of coupled systems transitions through the lens of mobility, and integrate the perspectives of multiple stakeholders with fundamentally different interests and priorities.

Ongoing socioeconomic and environmental transformations in drylands make it imperative to examine the tradeoffs and co-benefits between the twin goals of food security for those dwelling in drylands and the ecosystem health of the rangelands themselves. These two goals, while
