This publication shows how land tenure laws, decentralization policies, institutional capacity building, common property management, conflict resolution and participatory development can be made more responsive to the needs of those practising transhumance today, or pastoralists, for ecologically and economically sustainable development in arid Africa. The scope of the book is holistic: social, economic, political and environmental issues are discussed in each contribution. The case studies focus on four key constraints to managed mobility: appropriate institutions at the local level; land use; land tenure and appropriate legislation; and conflict resolution. Although the case studies are from Africa, the issues and conclusions are just as relevant to pastoralism and common property management in other continents. Scientists, students, development experts, government officials and bilateral and multi-lateral development organizations will find new rsearch presented in this book of relevance to their work. Published in association with the UN Food and Agriculture Organization (FAO) and the Beijer International Institute of Ecological Economics.
