The Agricultural Production Systems Simulator (APSIM) is a modular modelling framework that has been developed by the Agricultural Production Systems Research Unit in Australia. APSIM was developed to simulate biophysical process in farming systems, in particular where there is interest in the economic and ecological outcomes of management practice in the(More)
Agricultural systems models worldwide are increasingly being used to explore options and solutions for the food security, climate change adaptation and mitigation and carbon trading problem domains. APSIM (Agricultural Production Systems sIMulator) is one such model that continues to be applied and adapted to this challenging research agenda. From its(More)
The applicability of models in addressing resource management issues in agriculture has been widely promoted by the research community, yet examples of real impacts of such modelling efforts on current farming practices are rare. Nevertheless, simulation models can compliment traditional field experimentation in researching alternative management options.(More)
Global food security requires eco-efficient agriculture to produce the required food and fiber products concomitant with ecologically efficient use of resources. This eco-efficiency concept is used to diagnose the state of agricultural production in China (irrigated wheat-maize double-cropping systems), Zimbabwe (rainfed maize systems), and Australia(More)
Biophysical simulation models (e.g. APSIM) using historical rainfall data are increasingly being used to provide yield and other data on crop rotations in various regions of Australia. However, to analyse the economics of these rotations it is desirable to incorporate the other main driver of profitability, price variation. Because the context was that(More)
Recent years have seen a growing interest in agricultural research for development (R4D) initiatives designed to address the need to make more effective use of research investments in the development process. While there remains some ambiguity about the precise nature of R4D, it is nevertheless clear that a shift to this approach is going to require(More)
This paper reports on the design and performance of an irrigation system associated with a rain shelter. The shelter is used in the closed position as a platform for multiple spray lines. This system automatically supplies, at a specified time, water of specified depth and delivery rate, either uniformly or on a specified gradient across the sheltered area.(More)
Cropmodels are common tools for simulating crop yields and crop production in studies on food security and global change. Various uncertainties however exist, not only in themodel design and model parameters, but also andmaybe evenmore important in soil, climate andmanagement input data.We analyze the performance of the point-scale cropmodel APSIM and the(More)
In the era of Operations Research/Management Science that preceded the DSS, models were used by experts primarily to identify optimum actions for manager clients “to substitute formal analysis for intuitive judgments” (Hutton, 1965). In the 1970’s, after thirty years of clients ignoring this normative approach, the DSS was heralded as a way to use models(More)
