The contributors to this volume have created a rich reference with a wide variety of theoretical and practical perspectives, methods, research ques-

tions, measures, indicators, and empirical findings on environmental conflict resolution (ECR). Despite the wealth of information provided, the contributors agree that more empirical work on ECR is needed. Whereas the contributors use different terms to refer to their work-evaluation, program evaluation, evaluation research, applied research, field research, or just plain research-they nevertheless reach a broad interdisciplinary consensus about the usefulness of this variety of perspectives. This volume covers a wide swath of a diverse ECR landscape and provides much food for thought. l Nevertheless, the current underdeveloped state of theory is a challenge for ECR research and evaluation.
