To keep up with global food demand, the UN estimates, six million ha of new farmland will be needed every year. Instead, 12 million ha are lost every year through soil degradation. Australia lost 36 million ha of agricultural land in just the four years from 2005 till 2009. Some of this lost land has occurred because of urban sprawl which is swallowing up some of our best soils close to cities that used to supply the fresh fruit and vegetables. A scathing report by the Royal Commission has gone as far to accuse the Murray-Darling Basin Authority (MDBA) of negligence and being "incapable of acting lawfully," apparently because they overestimated the amount of water returned to the river by a factor of ten.
