Australia reduced urban water use by investing billions in conservation, education, and efficiency
improvements. Began to reform the old water allocation system. instituted a system that guaranteed a minimum
supply of water for the environment, then divided the remainder into shares that could be quickly sold and
traded—or stored for the next season. Farmers fought the changes – but financial incentive to use less water –
became creative and more efficient. Overall, water usage dropped in both cities and towns.
