The field of urban planning is far-reaching in breadth and depth. This is due to the complex nature of cities, regions, and development processes. The knowledge domain of planning includes social, economic, technological, environmental, and political systems that continue to evolve and expand rapidly. Understanding these systems is an inter-disciplinary endeavor at the scale of several academic fields. The wide range of topics considered by planning educators and practitioners are often based on varying definitions of "planning" and modes of planning practice. This unique book discusses various elements and contributions to urban planning research to show that seemingly disparate topics do in fact intersect and together, contribute to ways of understanding urban planning. The objective is not to discuss how to "do" research, but rather, to explore the context of urban planning scholarship with implications for the planning academy and planning practice. This edited volume includes chapters contributed by a diverse range of planning scholars who consider the corpus of planning scholarship both historically and critically in their area of expertise. It is essential reading for students of planning research and planning theory from around the world.
