The Murray-Darling Basin is characterised by low but highly variable rainfall and surface runoff and a high level of surface water use. Regulation has altered the stream flow pattern dramatically, affecting river dependent ecosystems. Responsibility for land and water management is fragmented, producing varying (and sometimes disparate) policies, management, and modelling approaches. The Murray...

In this paper we present the architecture of an integrated management and decision support system which contains expert components dedicated to carry out specific tasks of the daily management in a pig breeding farm. Although these components form a mosaic of various task performing tools, their tight coupling and interaction enables the system to pre-estimate and evaluate the overall farm perf...

The maintenance of low-intensity farming is important for the conservation of habitats and species and is a particular issue in Europe as areas under extensive farming regimes continue to diminish. Current proposals for agricultural reform in Europe are seeking to retain and encourage extensive farming partly by seeking to redirect farm workers into non-farm activities such as leisure activitie...
