First published in 1926, this classic survey, which includes nearly 250 photographs, examines the traditional farming methods of the densely populated lands of China, Korea and Japan and shows how fertility can be maintained over many centuries through conserving and utilizing natural resources. In the Introduction, the author notes: `The United States as yet a nation of but few people widely scattered over a broad virgin land with more than twenty acres to the support of every man, woman and child, while the people whose practices are to be considered are toiling in fields tilled more than three thousand years and who have scarcely more than two acres per capita, more than one-half of which is uncultivable land.' Researchers and scholars in the fields of human geography, regional studies and earth sciences, as well as social and economic history will welcome this landmark study being returned to print.
