| We aim to model the impact of variability in and changes to water availability in the Murray-Darling Basin on flows available to the environment and irrigation, and impact on the value of irrigated agricultural production. Our objective is to understand the opportunities for changed management of the basin, how they are constrained by climate change and other factors, and how they might affect the returns to irrigation and flows for the environment, so that we may provide information to help plan for the future. In this paper we describe the model: in other papers in this conference we describe analyses of water availability and use in the basin based on this model. The hydrology component of the model is based on a simple, monthly water balance stocks and... |

| Climate change and the proposed Murray-Darling Basin Plan both result in less water for irrigation. Climate change is projected to take water from all uses including the environment, whereas the likely sustainable diversion limit in the Plan aims (amongst other things) to return water to the environment. We examine the impact on flows and the returns to irrigation of potential reductions in irrigation allocations, and the interaction with projected climate change impacts. Our analysis is based on an integrated hydrology – economics model of the Murray- Darling Basin, described in Kirby et al. (2012a). The model can quickly and easily run new climate or other scenarios, accounting for flows at key environmental assets. It uses a statistically calibrated... |
