We focus on social and urban metabolism in terms of material input, stock, and output for sustainability. Material stocks of buildings and infrastructure provide numerous services such as dwelling, transport, and communication. We account and analyze material stock and flow with statistical and geographical information system (GIS) databases, in the aim to improve the efficiency and productivity of raw material consumption from the neighborhood to the global scales.
