Abstract

Crop production in much of Australia is strongly influenced by the availability of water. Rainfallis highly variable in both amount and distribution and, as a result, so too are supplies of irrigation water fromexisting sources such as overland flow (catchment runoff), rivers and bores. The search for additional sourcesof irrigation water, coupled with the need for urban communities to dispose of large quantities of treatedrecycled water has led to increasing interest from communities in the reticulation of this recycled water toadjacent crop production areas for irrigation purposes. Proposals to use recycled water inevitably lead to acomplex range of production, economic and environmental issues. Computer-based simulation models cancapture many of the key factors and processes influencing such systems, and hence can play a useful role inexploring these issues. In this paper, we describe an approach that couples farming system and economicmodels, in a way that enables analysis of the likely benefits and risks of investing in recycled water. Thepaper includes a case study based on a farm in the Darling Downs, Queensland, which has a mixture of cropand irrigation sources.
