Its plenty and safe availability depends upon natural conditions, such as geology, precipitation, vegetation, etc., but also upon volume withdrawn for artificial purposes as well as on the characteristics used water (typically called ‘waste water’) is fed back to the hydrological cycle.  Most recent investigations and analyses reveal once more that the availability of ground water is critical in regions characterised by unstable social and economic conditions (Middle-East, Africa, etc.). Tensions among countries situated in such regions can substantially inhibit the sustainable supply with drinking water from ground water resources. From a technological point of view GIS-applications for the management of ground water resources become increasingly impor...

► LATEST NEWS: _sust invent 0.1 RC 2 is onlin e. go here... -- a note from _kt75 As of today the fourth issue of the Notes is available via: server1 | server2 .    ► As announced previousl y, t his last issue of the Notes is edited as special issue and concentrat es exclu sively on hydro power as an alternative energy source. This in particular in order to encourage critical (re-) consideration of this type of alternative energy. A key region is Africa. The Notes intend to highlight recent political deve lopments , technica l and s cientifi c trends and provide access to relevant information .  Aside this the Notes inform about: _sust invent 0.1 RC1 ( visit: http://kt75-mirror.blogspot.ch/p/kt75-interactive.html ) . _sust invent is a web-based cross-browser service that comprises technical, economic, environmental and geo-political information.

-- a note from _kt75   As of today _sust invent 0.1 release candidate 1 is available online: http://kt75-mirror.blogspot.ch/p/kt75-interactive.html .  _sust invent is a web-based cross-browser service that comprises technical, economic, environmental and geo-political information. It is aimed to provide qualitative and quantitative information about   ► renewable and non -renew able energy (current focus : hydro power)     ► transport (mobility infrastructure)   ► building and construction     ► education , e mployment and further social issues   The service provides both, foreground data as well as b ackground (i.e. meta ) data. The latter provides access to rather rare docu ments.   _sust invent is intended to assist researchers , engineers and consultants in their work. Th ere e x ist two versions of _sust invent 0.1 RC1 : _sust invent and _sust invent + . _sust invent is available free of charge . It provides access to the pr...

-- a note from kt75 In the past a number of articles addressed the issue of water shortages especially in Mid-East [ 1 ]- [ 4 ]. Focus in this region is on the Jordan valley and in particular on the so-called Disi-Aquifer [ 5 ], [ 6 ]. Accordingly, and despite the fact that the Disi-Aquifer constitutes an almost non-renewable water resource (fossil water) the exploitation seems to have started seriously [ 5 ], [ 7 ]. This obviously also due to social pressure (refugees from Syria) [ 8 ], [ 9 ]. All this affects the water supply conditions in the Mid-East region adversely [ 10 ]-[ 12 ] and represents a huge challenge in terms of political and economic decision making [ 13 ], [ 14 ]. Most importantly is certainly the insight that fossil water resources represent non-renewable water sources. They may help facilitate safe water supply for a short time but (due to almost nonexistent replenishment) may not be considered as durable long-term water supply alternative.
