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 …
