Abstract: | The meaning of sustainability in water resources management has changed through the time. Initially, meeting water demand
was the dominant concern. While later quality issues became more important followed by wider water reuse, today sustainability
must include a whole range of aspects (e.g., energy, pollution, persistent chemicals) on various spatial and time scales.
New approaches to define sustainability metrics are needed that include three essential elements: the sphere of sustainability,
its time horizon and its metric. |
