The Ecological Footprint of cities and regions: comparing resource availability with resource demand

Cities and regions depend on resources and ecological services from distant ecosystems. The well-being of city and region residents is affected by both the health and availability of these ecosystems, especially in today's ecologically strained world. The management of a city or region's resource metabolism, including the natural capital that supports these flows, is becoming increasingly a central concern to cities and regions that want to succeed. Urban infrastructure is long-lasting and influences resource needs for decades to come: which cities are building future resource traps, and which are opportunities for resource-efficient and more competitive lifestyles? Reliable measures comparing the supply of natural capital to human demand are indispensable for managing resource metabolism, as they help identify challenges, set targets, track progress and drive policies for sustainability. This paper describes one such measurement tool: the Ecological Footprint. After explaining the assumptions behind the Footprint and describing some representative findings, it provides examples of how this resource accounting tool can assist local governments in managing their ecological assets, and support their sustainability efforts.
