This important new book is an extensive, yet concise overview which critically surveys the application of economic valuation techniques to environmental problems in less developed countries. The authors argue that economic valuation has just as important a role to play in the developing as in the developed world in valuing environmental resources and change. Additionally, the information which such techniques provide is invaluable when helping to devise sound environmental policies. The book demonstrates that economic valuation is of extreme importance in raising the profile of the environmental aspects of development initiatives and policies, and that the application of economic valuation is both widespread and successful in developing countries.This book will be essential reading for professional environmental economists, particularly those working in the developing world, project appraisal analysts, policymakers in development organizations and graduate students of development and environmental economics.
