Pastoral livestock production is crucial to the livelihoods and the economy of Africa’s semiarid regions. It developed 7,000 years ago in response to long-tern climate change. It spread throughout Northern Africa as an adaptation to the rapidly changing and increasingly unpredictable arid climate. It is practiced in an area representing 43% of Africa’s land mass in the different regions of Africa, and in some regions it represents the dominant livelihoods system.

In many countries, pastoralism has historically been practiced in areas that are now partitioned by international boundaries. This is a major barrier to sustainable resource management and to pastoral development. However, there are examples from around the world of efforts to facilitate transboundary movements and transboundary ecosystem management by pastoralists. This report examines how pastoral mobility has been impacted by the creation of unnatural boundaries within their landscapes and how societies cope with these constraints through legal or informal arrangements.

Crown diameter and tree density were measured in 52 communities in the Sudan-Sahel using satellite imagery to determine the relationships between rainfall and distance from community center to crown size diameter and tree density. As distance from the community center increased, tree density and crown diameter decreased. As rainfall increased, tree density decreased while crown diameter increased. Distance from the community center is a proxy for age since urbanization and our results indicate that older parts of communities show longer and more consistent tree management.
