Pastoralist societies face more threats to their way of life now than
at any previous time. Population growth; loss of herding lands to priv
ate farms, ranches, game parks, and urban areas; increased commoditiza
tion of the livestock economy; out-migration by poor pastoralists; and
periodic dislocations brought about by drought, famine, and civil war
are increasing in pastoralist regions of the world. Mongolia and Chin
a, however, have seen a revitalization of pastoral production with dec
ollectivization. This review examines problems of pastoral governance
and development including the ''tragedy of the commons'' debate, threa
ts to common property rights, the effects of commercial ranching on pa
storal economies, decollectivization in the former socialist countries
. and the current state of development policies of Western donor count
ries. Case examples from the Maasai and Barabaig of East Africa and pa
storalists of Mongolia and China illustrate these changes.
