The Sustainable Urban Systems section of the ISIE is concerned with applying methods of industrial ecology towards the sustainable development of cities, their supporting hinterlands, and the networked infrastructure that connects them. This is an applied, cross-cutting section in which various IE methods, such as LCA, MFA, EIO, complex systems theory and thermodynamics, are applied at the urban scale. Issues addressed include (but are not limited to): developing urban infrastructure for low carbon cities; urban waste management and material recycling; urban transportation; green buildings; sustainable water and nutrient management; urban energy systems; resilient cities; adapting cities to climate change, and provision of infrastructure for the urban poor. Practical solutions to these issues are informed through study of urban ecology, urban metabolism and the dynamics of city growth. Membership of the section is broad ranging, including: urban planners, architects, geographers, engineers, economists, scientists, and others.
