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...

Historically, communities living in these arid and semi-arid regions always shared the water of rivers, springs and wadis, although this was more out of necessity than idealism. Water resources were traditionally managed at the local level, with tensions emerging between Bedouins, shepherds, pastoralists and growing urban centres. Water management and irrigation schemes – such as the underground aqueducts or falaj networks found in Bahrain, Oman, Saudi Arabia and Yemen – sustained different communal needs for dozens of centuries, while the marshes of Mesopotamia, the Tigris floodplain and the Jordan River Valley were cultivated and sustained successive civilizations since earliest of times.

-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q02/2014 . Abstract In 2013 faced with a critical shortage of water, the Iranian government called for water conservation and greater water use efficiency nation-wide. Despite imminent shortages , water use in Iran remains inefficient, with domestic use 70 per cent higher than the global average. Iran has a national population of 75 million people, 12 million of whom reside in the capital; demand for water is rapidly increasing, even as major lakes and groundwater resources begin to shrink. Population growth, more frequent droughts and the effects of climate change are creating the ‘perfect storm’ for future water insecurity. We are left with the question, are the proposed changes too little, too late? Paper (abbrev.) Security in the Middle East continues to focus on the political and geostrategic priorities of regional states, but a greater challenge has now presented itself, in the for...

-- a _kt75 | note Download: Quarterly Notes on Sustainable Water Management - Q02/2014 . The most recent issue of the Quarterly Notes on Sustainable Water Management (Q02/2014) is freely available. In continuation of the successful publication of the Quarterly Notes on Sustainable Water Management the current issue concentrates on a broad range of topics including land subsidence, implications of climate change on ground water regimes, technical developments in the small hydro power sector, etc. Geographically, the Notes once more focus on regions exposed to complicated water supply conditions: Middle-East and Asia. A number of publications tackle the named issues in detail and provide cutting-edge insights on present developments. An important, because seldom considered, region represents the Horn of Africa and the water supply issues encountered there. A comprehensive overview is provided by a dedicated report. As always all reprints are completely refere...

-- a _kt75 | note Download: Quarterly Notes on Sustainable Water Management - Q01/2014 . The most recent issue of the Quarterly Notes on Sustainable Water Management (Q01/2014) is freely available. This release of the Notes comes along with a substantial diversification in terms of content. As with this issue the section 'Energy' is inserted immediately after the section 'Technology'. By this, it is intended to emphasise and consider the importance of water as an important energy carrier. Thematically, this issue concentrates on two highly sensitive issues affecting sustainable water management: the extraction of natural gas and crude oil by measn of hydraulic fracking on the one hand and the accounting of virtual water (especially with regarding to trading and agriculture) on the other hand. Both topics pose severe challenges. Whereas the former is often criticised to affect the natural water balance, in particular the mechanisms of the groun...

Jordan is currently one of the world‟s ten water poorest nations, a situation which is being exacerbated by a rapidly growing population. Jordan has a climate ranging from Mediterranean to Arid with approximately 80 per cent of the country receiving less than 100mm of precipitation annually. Evaporation ranges from around 2000mm per year in Zarqa in the north west of the country to over 5000mm per year in Ma‟an in the south. Renewable freshwater resources are of the order of 750-850 million cubic met...
