Dryland Management: Economic Case Studies - Dixon, John A. a James, David E. a Sherman, Paul B.

Drylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. This book surveys a wide range of drylands and their resources.
