This memorial collection of papers authored and co-authored by Ian Langford represents some of the most thoughtful and innovative contributions to the literature regarding the holistic analysis of environmental and health risk issues. It provides important foundations for the development of a mixed methodological approach to addressing such issues. These carefully chosen papers span a number of disciplines, including statistics, environmental risk analysis, human geography and economics and represent the diversity, innovation and analytical rigour of Ian Langford's writing.

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.

Ecosystem services can be broadly defined as the aspects of ecosystems that provide benefits to people. This book provides guidance on the valuation of ecosystem services, using the case of multifunctional wetlands to illustrate and make recommendations regarding the methods and techniques that can be applied to appraise management options. It provides a review of ecosystem service valuation rationale, including its importance from both a policy and project appraisal perspective, and a useful reference when considering policy and appraisal of ecosystem management options. It shows how legal obligations and other high-level management targets should be taken into account in valuation exercises, thus giving important policy context to the management options.

The authors set out what they call an Ecosystem Services Approach to the full appraisal of the role of ecosystem services in the economy and society. Although concentrating on wetlands, the approaches suggested provide an assessment framework that can be applied to other types of ecosystem assets.
