Agricultural virtual water flows within the USA
… there has been a surge of interest in the water resources embodied in international trade, referred to as `global virtual water trade'. In this paper, we present a comprehensive assessment of virtual water flows within the USA, a country with global importance as a major agricultural …

Frameworks for estimating virtual water flows among U.S. states
<p>The United States is the world's top virtual water exporting nation, but not much is known about the country's internal virtual water flow patterns and the volumes involved. Previous studies have suggested that the import of virtual water, defined as the volume of water required to produce a …

Climate Change and Virtual Water: Implications for UK Food Security
Demand for both food and water are projected to increase substantially in the next four decades. Water scarcity is also projected to increase in scale and complexity. Climate change is projected to increase temperatures, spatio-temporal variability in rainfall, frequency and severity of droughts …

Trends in Virtual Water Export from the High Plains, 1950-2010
<p>Water and land are both essential to humans in order to produce food. Over the last century the human population grew rapidly and with it the demand for food. One consequence is an amplified demand for water, which may cause an increase in water scarcity. A possible solution is to import virtual …

An Examination of the Influence of Landmarks in Human Spatial Navigation Using a Virtual Water Maze
… excelled with the invention of the Morris Water Maze (Morris, 1984). In this task animals are required to find a platform, hidden somewhere in a large circular pool of water (below surface level). As animals cannot see the goal directly, they must use various cues in the environment to …

An Analysis Of Virtual Place Learning/navigation In Children And Young Adults Prenatally Exposed To Alcohol
… exposure impairs performance on the Morris water maze. This task requires the rodent to use distal room cues to locate a hidden platform in a pool of opaque water. Successful performance on this task is dependent upon hippocampal function. Rodents prenatally exposed to alcohol are impaired …

A new class of neural architectures to model episodic memory : computational studies of distal reward learning
… This simulated environment realizes the Morris Water Maze task, a well established biological experimental test of distal reward learning. The embodied neural architecture is treated as a virtual rat and the environment it acts in as a virtual water tank. Performance levels of the neural …

Energyshed to Watershed: Linking Water and Energy Consumers to Their Environmental Impact and Water Resources
Watersheds are fundamental systems for supporting the needs of society, yet the availability of water within natural watersheds often does not align with the growing demands of human activities. This disparity frequently compels cities and agricultural hubs to depend on water sources well beyond …
