Planning Theory has a history of common debates about ideas and practices and is rooted in a critical concern for the ”improvement” of human and environmental well-being, particularly as pursued through interventions which seek to shape environmental conditions and place qualities. The second volume in this series covers in detail critical political economy, the turn to diversity and critical pragmatism. It provides an authoritative collection, in an accessible form, of the most important and influential articles and papers along with a detailed introduction by the editors. It offers a unique reference resource for planning scholars, upper-level undergraduate and post-graduate students.
