Book Review

The present volume contains information for local tropical as welt as world wide agricultural improvement, and may as such be regarded as a contribution to the continuing so-called green revolution. It is the first of an intended series of publications surveying the botany and agriculture of useful cultivated and wild growing plants of Ethiopia. As this country displays a great variety in its physical and biological environment in connection with a great diversity of local inhabitants applying various agricultural methods, it harbours a wealth of food plant species. The first part of the book, up to page 46, deals with general considerations, with a chapter on the physical and biological environments in Ethiopia, covering such topics as geology, topography, climate, soils, and natural vegetation, and including a very interesting description of the types of agriculture practized in Ethiopia.
