It is vital that we adopt interdisciplinary approaches such as ecological economics to gain an understanding of the values that determine human interaction with, and use and abuse of, the environment. This book is a model of applied ecological economics. It presents an accessible introduction to the subject while at the same time broadening its theoretical basis by introducing a post-positivist, participatory method. The theoretical framework is applied to case studies in biodiversity conservation, drawn from around the world and a range of different ecosystems. The book is a suitable textbook for students of ecological economics and an ideal introduction for scientists and environmentalists needing to understand the role of economics in ecology and conservation.
