Energy and Water Interdependence, and Their Implications for Urban Areas
There are many definitions for sustainability. Mathis Wackernagel, creator of the ecological footprint concept, defined sustainability as “securing people’s quality of life within the means of nature”. The United Nations’ World Commission on Environment and Development (the Brundtland Commission) defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” . Throughout this report, sustainability will be defined as the development of the anthroposphere within the means of nature.
