Pathways to Urban Sustainability: Lessons from the Atlanta Metropolitan Region: Summary of a Workshop explores the Atlanta region's approach to urban sustainability, with an emphasis on building evidence based foundation upon which policies and programs might be developed. The two day workshop held on September 30 and October 1, 2010 examined how the interaction of various systems (natural and human systems; energy, water and transportations systems) affect the region's social, economic, and environmental conditions. The intent of this workshop summary is to analyze a metropolitan region so that researchers and practitioners can improve their understanding of the spatial and temporal aspects of urban sustainability.
