The Planner’s Guide to Natural Resource Conservation: (eBook)

Adrian X. Esparza is Associate Professor in the School of Natural Resources at the University of Arizona (Ph.D. 1987, University of Illinois-Urbana). He taught previously in the School of Planning, College of Architecture at the University of Arizona. His research focuses on exurban land development in the southwest United States and urbanization in the United States-Mexico border region. He has published dozens of articles in the fields of urban and regional planning and regional science. Guy McPherson is a Professor in the School of Natural Resources at the University of Arizona (Ph.D. 1987, Texas Tech University). He also worked for the University of Georgia, Texas A & M University, University of California-Berkeley, and The Nature Conservancy. His research focuses on development and application of ecological knowledge. His scholarly efforts have produced dozens of journal articles and eight books.
