Description

Inappropriate grazing management strategies have caused degradation of the extensive rangelands of northern Australia involving changes in pasture composition, invasion of woody weeds, a reduction in total vegetative cover and increased soil erosion. This degradation has reduced productivity, increased variability In production, and threatened the long-term sustainability of the land resource base. To help address the problem, a prototype micro computer-based decision support system, called Landassess DSS, is under development for the monsoonal tallgrass woodlands of northern Australia. Landassess DSS will use object­oriented design and artificial intelligence techniques to integrate a knowledge-based system, a relational database management system and a geographical information system. Using a theoretical framework based on the State-and-Transition model, Landassess DSS will help the user to assess the current stale of a grazing management unit (e.g., paddock, property) and to evaluate the potential environmental and economic risks of alternative grazing management strategies.
