Sustainable irrigation: How did irrigated agriculture in Australia's Murray-Darling Basin adapt in the Millennium Drought?

The aggregate responses that we report are consistent with reported data on strategies used by irrigators to adapt to less water, including water trading, input substitution, changes to crop mix, and improvements to technology leading to reduced water application rates and yield increases. These responses likely also provide some insight on how irrigators will adapt to future more permanent reductions in irrigation water and assist in the identification of constraints to adaption.
