This Oxford Encyclopedia of Environmental Economics focuses on the most important research topics in environmental and natural resource economics, with a treatment of close to 100 different research areas. Each chapter offers a critical analysis of key contributions to the field. The contributions, authored by experts from institutions around the world, are useful for informing policy as well as future research. The chapters will prove a vital point of demarcation for researchers and practitioners. It will be a good foundation for researchers who want to extend the frontiers of the state of the art in a given area of research, as well as those who want to base their empirical work on the best possible theoretical pillars. Practitioners can more effectively develop policy, as they see the documentation of cause and effect relationships in the appropriate chapters. The chapters are an ideal starting point for Ph.D. students developing thesis topics. Professors will want to assign chapters in the encyclopedia to undergraduate and graduates students in classes in environmental economics, natural resource economics, fishery economics, forest economics, economic development, health economics and sustainability. Students will find the chapters useful as a starting point for writing research papers in these classes.
