This book addresses the economic component of ecologically sustainable development in the Pacific. It is primarily concerned with the role that conventional economic issues plays in the viability of natural resource and environmental projects in the Pacific. Key economic concepts, principles and topics covered in this book reflect issues that project managers are likely to encounter during the life cycle of a project. The book is designed to provide a practical and operational approach to considering economics for resource and environmental management, and to guide individuals involved in designing and implementing resource and environment projects in the Pacific. Although the book is written with project managers in the Pacific in mind, and uses case study examples from the Pacific islands, the economic concepts and principles covered in this book are also likely to be relevant to project managers around the developing world.
