The book "Introduction to Environmental Impact Assessment" is designed to provide a critical overview of the theory and practice of EIA as operated internationally. It is aimed at students taking first degrees in planning, ecology, geography and related subjects with EIA content; and at postgraduate students taking courses in EIA or Environmental Management. It gives the students a good introduction to the history and evolution of EIA in the world and particularly in Ethiopia. It explains about the major concerns of the EIA components, how data on each environmental component are collected, what standards and regulations apply, how impacts are predicted, what mitigation measures can be used to minimize or eliminate impacts and where further information can be obtained. It covers the existing legislation well and provides interesting case studies and examples along the way to keep the reader interested.
