Entrepreneurs are turning to Oak Ridge National Lab's supercomputer to make all sorts of things, including maps that are much more accurate in predicting how a neighborhood will fare in a flood. -

Water: Think Again | Kaveh Madani | TEDxKish

Posted By britneyg in Hydrology , Planning and Management , Miscellaneous

The future war could be about water. In this great TEDx talk, Kaveh Madani discusses the possibility of water wars in the future and our opportunities to prevent them. Based on his discussion, the fact that water is linked to many other resources and issues (food, dignity, energy, independence, etc) provides opportunities for trades and cooperation. He discusses how he uses game theory and gaming to study and analyze water conflicts and presents his personal experiences and surprises in Africa where he found that theory does not necessarily support reality. -

California drought: Almond growers fight back over reports they are causing chronic water shortages

Posted By britneyg in Planning and Management

As California descends ever deeper into a potentially devastating drought, with residents facing unprecedented demands to cut water use, everybody is looking for somebody else to blame. But perhaps the most high-profile scapegoat in the parched Golden State is not a somebody but a something: the highly nutritious, increasingly notorious almond.

California grows 80 per cent of the world’s almonds, but it is two other widely reported statistics that have caused controversy: cultivating a single thirsty almond takes more than a gallon of water, and almonds alone account for almost 10 per cent -

A plant-based diet can help save water

Posted By teddyRIO in Planning and Management , Miscellaneous

Animal agribusiness is the most water-intensive of all agriculture. You’d save more water skipping one purchase of a chicken than by skipping six months of showers. Experts agree that plant-based proteins use less water than their animal-based counterparts. -

Central Valley's growing concern: the mix of oil, water and crops - LA Times

Posted By Kaveh in Hydrogeology , Planning and Management , Water Quality

Here in California's thirsty farm belt, where pumpjacks nod amid neat rows of crops, it's a proposition that seems to make sense: using treated oil field wastewater to irrigate crops. -

5 facts you need to know about Lake Mead’s water crisis

Posted By Kaveh in Planning and Management

1- At full volume, Lake Mead and Lake Powell had 50 million acres feet of water in storage at a height of 1220 feet above sea level.

2- Now Lake Mead is at record low levels and getting lower, causing consequences for the entire region.

3- The Southern Nevada Water Authority built an underground tunnel to prepare for this scenario.

4. They took measures to prevent water use in residential areas and made changes to water usage in Las Vegas.

5. Investing in infrastructure can lessen the consequences, but we need to first identify ourselves as citizens of the watershed. -

A system of systems approach to energy sustainability assessment: Are all renewables really green?

Posted By Sina in Planning and Management

• We propose a System of Systems (SOS) approach for energy sustainability evaluation.
• We develop a new SOS-based sustainability indicator, Relative Aggregate Footprint (RAF).
• RAF integrates four resource use efficiency criteria: carbon footprint, water footprint, land footprint and cost.
• RAF values show that not all renewables are resource-use-efficient (e.g., biofuels).
• Geothermal and onshore wind have the lowest; and coal, oil and biofuels have the highest RAF scores.

Renewable energies are emerging across the globe in an attempt to slow down global wa -
