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

The German government has committed the country to an 'Energiewende', in which at least 80% of electricity production and 60% of primary energy needs are to be supplied by solar , wind , and other renewable energy sources by 2050. A big open question is how the intermittency of renewable energy sources like wind and sunshine can be reconciled with the need to reliably supply energy whenever and wherever it's needed, whether to heat homes, fuel trucks and trains, or power electrical equipment. 'Power-to- gas ' and 'power-to-liquids' could be the answer, according to engineers and researchers who spoke to a packed hall at the third annual conference of the Power to Gas Association in Berlin on Wednesday (2.7.2014), hosted by the German Energy Agency (DENA) . Michael Sterner, a professor at East Bavarian Technical University in Reg

-- 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
