We have always had land in which the agricultural productivity is
limited because there is not enough moisture. Systems of farming
and burning often degrade dryland further until it is desert.
Today, however, the problem is becoming much more serious. Over 20
per cent of the world's population lives in dryland areas, and
unless action is taken drylands will increase dramatically. This
book focuses on the people who live and .farm in the drylands,
their use of land resources and the economic returns from their
decisions. In a clear and thorough economic appraisal, the authors
show how it is still possible to arrest the problem. Originally
published in 1989
