In recent years, numerous theories about sustainable development and urban living have emerged. New urbanism, landscape urbanism, ecological urbanism, sustainable urbanism, are just a few to mention. Each of these planning and design theories introduces new ideas and principles; some of them even issue manifestos. How different actually are these urbanisms? Does one preclude the other? How do these theories contribute to sustainable development? This course reviews the most current among these movements, their basic tenets and positions. Students will apply observations derived from the comparison of urbanist theories to sample urban and suburban sites, and draw conclusions about sustainable development. Course discussions and assignments are aimed at establishing sound and well-informed professional approaches.
