Increases in global energy requirements could lead to a rise in the energy sector's water footprint of up to 66% in the next 20 years, new research suggests. As part of a sustainable future, any energy mix must enable a reduction in greenhouse gas (GHG) emissions. However, some renewable sources, such as biofuels and large-scale hydropower, have large water footprints, a factor which must also be considered in energy policies, the researchers say. ...

Streamflow Generation Processes: Selection, Introduction and Commentary by Keith J. Beven
In this first volume, the selection spans the period from 1933 to 1984, commencing with HortonÃs early papers on infiltration in the hydrological cycle, and on maximum groundwater levels. With the aid of the commentaries, the papers provide a stimulating insight to developments (and disagreements), de ... Read More
The situation of water resources in Iran has passed beyond the critical condition.At present, 96 billion cubic meters of the country's total 120 billion cubic meters of renewable water resources is being consumed annually. If 40-60 percent of renewable water resources is consumed in any country, that country is said to be in a critical condition! During the past decade, precipitations have declined to 242 millimetres from 250 millimetres. The water shortage has reached a critical level in Tabriz, Isfahan, Khuzestan, Qum, Mashhad and Hamadan provinces ... Read More
Nuclear proliferation, religious militancy and income inequality are all major threats to Middle East stability. Sadly, a new one is brewing: water scarcity.
The human causes are clear: rapid population growth, antiquated infrastructure, the over-pumping of aquifers, inefficient crop practices and pollution from fertilizer and pesticides. Then there are the factors that climate change is accel ... Read More
A work of art that doubles as powerful talking points and a visual guide.
Reports released by the Intergovernmental Panel on Climate Change (IPCC) can be daunting, even for science and policy insiders. The full Physical Science Assessment, the first installment of the Fifth Assessment Report (pdf), released in manuscript form earlier this year, is over 2,000 pages long.
And even the Summar ... Read More
Why do cold, rainy summers in Europe follow intense volcanic eruptions in the tropics? A research team may have found the answer: volcanic emissions in the atmosphere block sunlight and can thereby affect the amount of precipitation in other parts of the world.
Historical records provide evidence that strong volcanic eruptions in the tropics are often followed by a cold and rainy summer in Centr ... Read More
- The world's energy systems are inextricably linked with water systems. - With demand rising for both resources, water scarcity can threaten the long-term viability of energy projects and hinder development. - To mitigate the risks of the challenge, the World Bank has launched Thirsty Energy, a global initiative to help countries prepare for an uncertain future now by quantifying tradeoffs and identifying synergies between water and energy resource management. ...

Perhaps you're wondering what the hydrosocial cycle is, although I suspect you can guess. Here's a good definition from the abstract of a paper by Jamie Linton and Jessica Budds, 'The Hydrosocial Cycle: Defining and Mobilizing a Relational-Dialectical Approach to Water':
The hydrosocial cycle is based on the concept of the hydrologic cycle, but modifies it in important ways. While the hydrolog ... Read More
A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously thought. Once the fourth largest inland sea in the world, the Aral Sea has lost 90 percent of its water volume over the last 50 years. Its watershed -- the enormous closed basin around the sea ... Read More
