The implications of spontaneous range enclosure for African livestock development policy
This paper examines a process - the spontaneous enclosure of the range by livestock owners - which may rise new problems but also permit new approaches to the development of the African livestock industry. Drawing on case material from Sudan and Somalia, the opening section of the paper discusses some of the spontaneous range enclosure. It is suggested that the conditions which give rise to enclosure movements - drought, overstocking, water development, the increasing commercial value of livestock production, and the breakdown of collective forms of land - management - are factors which are common to much of dry, pastoral Africa. The final issue posed by range enclosure concerns the long-term planning and policy implications of the process

Fragmentation in semi-arid and arid landscapes: consequences for human and natural systems
Exploring the concept of fragmentation, the ecological processes interrupted by fragmentation, and the social consequences of fragmented landscapes, this book presents a timely synthesis on the effects of fragmentation on arid and semi-arid pastoral systems throughout the world.
The global significance of the world’s rangelands is large, with these arid and semi-arid systems making up almost 25% of the earth’s landscapes – and supporting the livelihoods of more than 20 million people. These ecosystems are also home to several of the planet’s remaining megafauna, as well as other important species. Yet fragmentation across these rangelands has significantly impaired the ability of both people and animals to compensate for temporal heterogeneity in vegetation and water by exploiting its spatial heterogeneity, resulting in limited resource availability.
The case is developed that while fragmentation arises from different natural, social and economic conditions worldwide it creates similar outcomes for human and natural systems. With information from nine sites around the world the authors examine how fragmentation occurs, the patterns that result, and the consequences of fragmentation for ecosystems and the people who depend on them. The book will provide a valuable reference for students and researchers in rangeland ecology, park and natural resource management, environmental and ecological anthropology, economics and agriculture
