There have been a number of excellent books on our own problem of soil erosion and ""deserts on the march"" -- but here is a book which opens one's eyes to the fact of its being a world problem. Africa, Australia and New Zealand, China, India and Japan -- all are faced with the problem in different degrees, and in all some measure of relief is being sought. Vanishing Lands approaches the subject scientifically, and is an exhaustive study on the causes, the forms it takes, the results economically, physically and socially -- and the probable futures. Various types of conservation are discussed, pros and cons presented. A book for a sharply defined market, but within those limitations, a book that meets every need.
