Environmental management is often complicated and multidisciplinary and the issues that arise can be difficult to solve analytically. Often, decision makers take ad hoc approaches, which may result in the ignoring of important stakeholder opinions or decision criteria. Multi-criteria decision analysis (MCDA) provides a framework by which these types of decisions can be made but, despite being used effectively in many fields, it is not often used in environmental management.
Given the novelty and inherent applicability of this decision making framework to the environmental field, there is a need for more teaching tools for MCDA. In particular, there is a need for a case study based approach to help readers navigate the many MCDA methods and decide how to apply them to a specific case.
Through a collection of case studies, Multi-Criteria Decision Analysis: Environmental Applications and Case Studies gives readers the tools to apply cutting-edge MCDA methods to their own environmental projects. It offers an overview of the types of MCDA available and a conceptual framework of how it is applied, with the focus on its applicability for environmental science.
Taking an in-depth look at the case of sediment management, the book introduces different steps of MCDA processes—from problem formulation and model development to criteria weighing and alternative scoring. The authors then explore the case using various MCDA methods, which allows readers to see clearly how the methodologies differ and gain a better understanding of the mechanistic operation of the analysis.
A series of case studies in nanotechnology collectively demonstrate the application of MCDA in situations of high variability and uncertainty that require the integration of technical information and expert judgment—an area where MCDA clearly shines. The authors describe multiple decisions—from risk classification to value of information analysis to the assessment of potential research and funding investments—that readers may face in dealing with emerging environmental threats.
Demonstrating the broad applicability of MCDA methods for different types of cases, the book presents a series of case studies ranging from oyster restoration to oil spill response. In conjunction with these cases, the book also provides corresponding decision models that are implemented by the DECERNS software and allow users to examine the same case using multiple MCDA tools. The DECERNS software and models are available for download at www.crcpress.com.
Intended both as a research and teaching tool, this book inspires creative thinking when applying MCDA to complicated environmental issues.
Currently, the most important trend in environmental assessment is the increasing emphasis on informing the decision-making process. With this book, Igor Linkov and Emily Moberg provide a useful introduction to the most versatile tool for linking estimates of risks or impacts with the many other considerations that inform environmental management decisions.

Where the U.S. government is in need of effective and reliable environmental tools to guide leadership, Linkov and Moberg’s MCDA is a common sense approach to balance the science, social, behavior, and economic factors associated in making complex decisions—a true systems approach seeking to find an acceptable and sustainable state of equilibrium.

… an excellent resource for researchers, practitioners, teachers and students interested in the use of formal decision analysis methods in environmental policy. The case study format allows the reader to grapple with the different methods and the associated software in context, the explanations are clear but sophisticated, and the discussion questions are crafted to encourage real student engagement …

The book is a valuable complementary addition to textbooks on the topic as it provides a very easy to follow presentation of the main methods. The approach is based on working through case studies using the DECERNS software. I am sure that practitioners will find this book a very helpful first step into the practice of the methodology.

I like how it gives a non-partisan treatment of all the different techniques, how it demonstrates them all on comparable problems so that it is easy for the reader to keep straight what is different and what is similar, and that the case problems themselves are realistic so it is clear how one might use this in practice.

In our society, environment is a ‘common good’. That is why stakeholders and citizens seek for more transparency and accountability within decision processes. The authors have offered us a set of practical experiences and have contributed to popularize multi-criteria decision analysis methods and tools by respecting the difficult equilibrium between conceptual/technical precisions and operational validation. This book will be a precious document for practitioners, regulators, researchers and students.

This book describes methods and applications of multi-criteria decision analysis. But it goes beyond models and theory to provide case studies and discussions of multi-criteria decision analysis applied in specific—and varying—circumstances. The book provides tools. It also inspires creative thought by offering examples that can be a springboard for policy makers and other decision makers to think about its relevance and utility in the many circumstances they face.
