_NEW: follow the development of the new web-presence wolframscharnhorst.blogspot.com print download: http://bit.ly/185cRt9 Sustainable urban water supply represents a key issue today as well as in the near future. Often networks are out of date, leakage or plugging is a common issue and investments need to be considered very careful. In addition, the behaviour, i.e. the demand of the consumers varies strongly. The present issue of the Quarterly Notes on Sustainable Water Management (Q04/2014) – Managing the Urban Water Supply - tries to provide an overview of innovative articles addressing the above issues in-depth. As always, a summary of news about the development of the web-portal is given. In the fifth year of its operation the platform is subject to a thorough re-design. This implies that the former _kt75 | mirror ( http://kt75-mirror.blogspot.com/ ) is now integrated into the large information portal http://wolframscharnhorst.blogspot.com . Via th...

Conventional sewage treatment plants are designed to clean this water to a degree that can be discharged to rivers or the ocean without major environmental or public health impacts. In many parts of the world, sufficient fresh water supplies are increasingly difficult to source. Water stressed cities now import water, pumped over large distances at a considerable energy cost. Los Angeles, for example, imports 8.9bn litres of water a day to meet the city’s needs. Other cities, such as Ashkelon in Israel, are investing in seawater desalination to produce drinkable water. But this process is also highly energy intensive and its application limited to coastal locations. An al...

However, environmental impacts associated with water consumption are largely neglected in these analyses. Incorporating water scarcity into water consumption allows better understanding of what is causing water scarcity and which regions are suffering from it. _progress | M replaces _kt75 | mirror. visit: http://progress-m.blogspot.com . ready: 01.07.2015. close ✕ In this study, we incorporate water scarcity and ecosystem impacts into multiregional input-output analysis to assess virtual water flows and associated impacts among 30 provinces in China. China, in particular its water-scarce regions , are facing a serious water crisis driven by rapid economic growth. Our findings show that inter-regional flows of virtual water rev...

Water is scarce but it continues to be wasted excessively in many industrial states, warns a new study by the World Wide Fund for Nature (WWF), predicting that a global conflict over water resources could bring billions in losses for the German market. EurActiv Germany reports.  Tomatoes from Spain, textiles from India, metals from South Africa, roses from Kenya; every year, Germany imports massive amounts of goods from around the world that would not be available without considerable water resources. But water is becoming an increasingly scarce global resource . In many countries, it has become more and more difficult to supply the population with adequate drinking water and irrigation for crops. Besides export-reliant countries with critical water resources, the effects of the shortage can be devastating for others as well. According to the World Wide Fund for Nature ...

-- a _kt75 | double reprint: EN/DE Download: Quarterly Notes on Sustainable Water Management - Q02/2014 . The environmental resources situation is shaped by changes in climatic conditions, coupled with pressures exerted by a rapidly growing global population, its increasing demands and the subsequent impacts on the environment. Current practices across the economy sectors are still not sufficiently ambitious in terms of sustainability ; they fail to ameliorate the stress conditions of vital resources like water. In recent years, the need has been highlighted for governance and management schemes that allocate resources appropriately among users (including the environment) and that promote the efficient use of such resources. The very nature of these needs calls for adequate policy responses. One of these policy responses — applied either separately or in combination with other economic or regulatory instruments — is water pricing . The use of such instruments brings a...
