Deliberately designed to be relevant, the authors focus on the common skills and generic aspects of EIA that underpin all impact assessment work! such as screening and scoping, impact identification, public involvement, prediction and monitoring, evaluation, and quality control. The methodology highlighted in the book can also be applied to several other environmental issues. The book includes report preparations, design measures and relevant mitigation steps that can be taken to reduce or avoid negative effects. Case Studies are presented, providing guidance to better understand, plan and prepare environmental impact assessments. The book is useful to graduate students of engineering and sciences and postgraduate students of engineering, economics, management and of other discipline who are part of project planning, implementation, operation and other related decision-making.
