GRAZPLAN: Decision support systems for Australian grazing enterprises—I. Overview of the GRAZPLAN project, and a description of the MetAccess and LambAlive DSS

Abstract Effective transfer of new information and technology to farming practice is the major goal of the GRAZPLAN project. GRAZPLAN contains a suite of complementary decision support systems (DSS) that incorporate results from research on grazing systems and are now being released through a commercial partner as aids to extension. These computer packages are designed to be used in conjunction with local weather and farm data to test the relevance of different management procedures for individual farms. The main DSS, GrazPlan, can be used to evaluate and optimize long-term management decisions in relation to profitability and sustainability. It is quite general in its application and modular in structure. The Australia-wide database of daily weather records, which drives this program, is the basis for two smaller DSS, MetAccess and LambAlive, which are described in this paper. MetAccess is designed to display and analyse daily weather records and provide users with estimates of the probability of specified weather patterns within the range of data from a specified locality. LambAlive is designed to predict the risk of lamb deaths from bad weather for specified localities and flocks and enables the user to test different procedures that may reduce these losses.
