| The soil acidity research and extension program in Western Australia is made up of a number of projects, all of which are working towards the overall aim of helping farmers to manage soil acidity profitably. As a means of achieving this aim scientists are undertaking research to provide information that will enable farmers to better quantify potential yield losses due to subsoil aluminium, and to adopt liming strategies to prevent these losses. In this paper we present estimates of the value to farmers of information provided by this aspect of the research. A bio-economic model is used to calculate the profitability of liming for different conditions and Bayesian Decision analysis is employed to estimate the payoff resulting from incrementally refining a... |

| Land managers in upper catchments are being asked to make expensive changes in land use, such as by planting trees, to attain environmental service targets, including reduced salt loads in rivers, to meet needs of downstream towns, farms and natural habitats. End-of-valley targets for salt loads have sometimes been set without a quantitative model of cause and effect regarding impacts on water yields, economic efficiency or distribution of costs and benefits among stakeholders. This paper presents a method for calculating a ‘menu’ of technically feasible options for changes from current to future mean water yields and salt loads from upstream catchments having local groundwater flow systems, and the land-use changes to attain each of these options at... |

| Meshed with the bio-physical and economic dimensions of rural land-use is a social dimension. Understanding the social and economic dimension of rural communities is critical if agencies are to develop effective policies and programs to improve natural resource outcomes. In this paper, we draw on research of the Boorowa community, located in the south-west slopes of New South Wales, to help understand how social changes in rural communities are impacting natural resource management in the Boorowa district. This included: *Identifying the catalysts for changing land-use in the Boorowa catchment, *Presenting an effective and efficient methodology for assessing the social and economic impacts of changes in land use at the catchment scale, *Identifying... |

| Sustained low prices for wool have resulted in a prolonged decrease in the profitability of wool production. The extent of the decline has led some farmers to question whether wool has a viable future on their farms. In many regions growers have substantially increased their area of crop and reduced their commitment to wool production. Stock numbers have declined appreciably and there is concern amongst some that the wool industry may not recover. This paper uses Western Australia as a case study for investigating the future of wool. In particular the nature and role of R,D&E in the industry is examined. The success of R,D&E is reviewed and the directions and likely impacts of future R,D&E on farm are discussed. |
