Murray Darling Basin

IVANHOE, NSW, AUSTRALIA - FEBRUARY 10: Natalie (left) and Samantha Turner drive out to their farm paddocks in the back of their dad's pick-up truck to help clean out watering troughs and check on windmills February 10, 2008 in Ivanhoe, New South Wales, Australia. The Turners, like many farm families in the Murray-Darling Basin have had to move most of their livestock to other regions of Australia because their own land is too dry to produce feed after years of drought. The Murray-Darling Basin of Australia has been plagued with severe drought since the late 1990's. (Photo by Amy Toensing/Getty Images)
