Like organisms, cities need energy, water, and nutrients, and they need to dispose of wastes and byproducts in ways that are viable and sustainable over the long run. This notion of "urban metabolism" is a model for looking systematically at the resources that flow into cities and the wastes and emissions that flow out from them-to understand the environmental impacts of cities and to highlight opportunities for efficiencies, improvements, and transformation.
Yale University's Journal of Industrial Ecology is pleased to announce a special issue on Sustainable Urban Systems that focuses on the integration of engineered infrastructures, people, and natural systems in the pursuit of environmentally sustainable cities.
This special issue examines topics such as the contribution of cities to global warming, opportunities for better management of waste electronics and storm water, and the use and fate of phosphorus--a resource that is both potentially scarce and polluting. The special issue presents research on 11 cities around the world including New York City, Delhi, Denver, Melbourne and London.
