| Evaluations of pathogen management options have focussed on assessing relative removal effectiveness as a basis for prioritising alternative management investment decisions. Using a case study of the Myponga catchment, South Australia, this paper presents results of a cost-effectiveness risk analysis of 13 catchment- and treatment-based water quality management alternatives for mitigating Cryptosporidium risk. A range of costs and benefits including set-up and operating costs, farm business costs and benefits, and environmental service benefits are considered in comparing the net cost associated with each management alternative. Considering the broader range of costs and benefits changes the relative cost-effectiveness of water quality management... |

| This study reviewed case studies and research focussed on the issues of managing native vegetation, the problems of salinity and the relationship between the two. It then addressed the economic feasibility of six tree planting configurations to reduce the impacts of salinity. The method used a spreadsheet model showing the benefits and costs of various planting configurations over a 30-year time span. This model can be used to assess the monetary net benefit/costs of reducing recharge of a vegetation management proposal. Inputs can be varied to tailor the model to different catchments. Even when applied to local groundwater systems, the impact on salinity in terms of land salinised, salt loads and dollars was small. These factors can represent major... |
