The recent drought saw the lowest inflows on record in the Murray-Darling Basin in 2006. Water use by irrigation in 2007-8 and 2008-9 was about one third that of pre-drought levels. Understanding how irrigation adapted to less water is key both to provide information to help plan for the future and data for model calibration. Complicating this objective was the concurrent international food price crisis of 2008 and an increase in water trading in the basin. This presents a challenge in unpacking the effects of commodity price changes, input substitution, productivity gains and water trading from the effect of reduced water availability. In this paper we seek Our objective is to unpack the various effects. We used publicly available price and production... |

This article is an economic analysis of reallocating River Murray Basin water from agriculture to the environment with and without the possibility of interregional water trade. Acquiring environmental flows as an equal percentage of water allocations from all irrigation regions in the Basin is estimated to reduce returns to irrigation. When the same volume of water is taken from selected low-value regions only, the net revenue reduction is less. In all scenarios considered, net revenue gains from freeing trade are estimated to outweigh the negative revenue effects of reallocating water for environmental flows. The model accounts for how stochastic weather affects market water demand, supply and requirements for environmental flows. Net irrigation revenue... |
