Historical Perspective of Accelerated Erosion and Effect on World Civilization

  1. H. E. Dregne1

Abstract

Accelerated erosion has made an impact, at one time or another, virtually everywhere in the temperate and tropical zones of the world that have been cultivated or heavily grazed or logged-over. The process has been slowed down or even halted in most of Europe, Canada, the United States, Australia, South Africa, South Korea, the Soviet Union, China, and Chile, and a few other countries. Erosion continues unabated in most of Africa, the Middle East, the Andes Mountains, and the Mediterranean countries. It is worsening rapidly in the hilly and heavily populated regions of southern Asia.
