Take pictures or draw three kinds of erosion-control practices. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.
It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries.
