Dryland Management Economic Case Studies [Hardcover]

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 extensiveagricultural systems dependent on rainfall or irrigation.Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources.Originally published in 19990List of ContributorsForewordPrefaceIntroductionI.
