This landmark volume presents the results of a comprehensive and coherent in-depth assessment of Ethiopian agriculture and draws lessons from it to generate actionable recommendations that will inform policy decisions and priority setting for agricultural transformation across Africa.

This unchecked expansion of land use puts the sustainability of the natural resource base under severe pressure. This book draws on a unique set of case studies from Ethiopia described and told from a truly African perspective.
