As the demand for freshwater and energy increases in San Diego County and Northern Baja, the fresh water supply continues to shrink while energy generation remains heavily dependent on fossil fuels. Due to these opposing trends in supply and demand, it becomes increasingly imperative to identify solutions that move these communities to their preferred state in which they are largely reliant on renewable energy and use water sustainably. Large-scale energy solutions include wind power, one of the must abundant sources of energy in these regions. ... Read more about Geodesign Session 5 Road Map

There are several different directions that our planet can take to address the ever growing need for water and energy. This will involve integrating technologies of a large and small scale into our grid and into our homes as well. There are two main technologies in which to address large scale water sustainability: desalination and ‘pure water’ recycling. As the California dries out, it is increasingly important to adopt proven strategies to maintain the current standard of living. ...

Peak oil has generated headlines in recent years, but the real threat to our future is peak water. There are substitutes for oil, but not for water. We can produce food without oil, but not without water.

We drink on average four litres of water per day, in one form or another, but the food we eat each day requires 2,000 litres of water to produce, or 500 times as much. Getting enough water to drink is relatively easy, but finding enough to produce the ever-growing quantities of grain the world consumes is another matter. ...

Abstract. There is growing concern in Europe about the possible rise in the severity and frequency of extreme drought events as a manifestation of climate change. In order to plan suitable adaptation strategies it is important for decision makers to know how drought conditions will develop at regional scales. This paper therefore addresses the issue of future developments in streamflow drought characteristics across Europe. ... Read more about Ensemble projections of future streamflow droughts in Europe

Nearly 70 percent of the groundwater stored in parts of the United States' High Plains Aquifer — a vast underground reservoir that stretches through eight states, from South Dakota to Texas, and supplies 30 percent of the nation's irrigated groundwater — could be used up within 50 years, unless current water use is reduced, a new study finds. ...

July 23 (AlertNet) - Disputes over water are common around the world, exacerbated by climate change, growing populations, rapid urbanisation, increased irrigation and a rising demand for alternative energy sources such as hydroelectricity.

Following are a few of the regions where competition for water from major rivers systems is fuelling tension.
