Abstract

Since the beginnings of human settlements, a reliable water supply has been a prerequisite for economic development and sustainable urban formations. It has also long been obvious that cities require water resources from far beyond their physical borders. In quantitative terms, this impact is evident in an alteration of the hydrological cycle caused by excessive water withdrawals and modifications to the natural discharge, retention and evaporation behavior as well as increased surface sealing and water-body regulation. Additional qualitative impacts on water resources are caused by household and industrial emissions of material and immaterial. This leads to an increased scarcity of water resources in city surroundings as a resource pool and, simultaneously, as a sink for contaminants and waste products. In this context, increasing population growth in urban areas and necessary economic development in developing countries will lead to enormous challenges in the integrated management of water resources. Whether or not conventional solutions can solve these problems remains highly questioned.
